Chapter 787: Heavenly Absolute Wood, Won the Bet
The two finally decided that they still had to take the initiative.
According to what Jing Chiyang said, in this Thunder World, except for the two of them who accidentally fell in, there is no one else, and according to what they have discovered so far, in addition to countless thunderstorms in the Thunder World, it is those three big things.
Well, at least for now, there are three in front of them.
That is, the brute dragon, the golden eagle, and the red pupil Tianlin that Jing Chiyang encountered for the first time, as for why he knew that it was the red pupil Tianlin, it was also very simple, Jing Chiyang used its spiritual power to probably conjure it up after Li Dai recognized it, but after seeing the behemoth, Li Dai did not feel relaxed at all, she felt that the red pupil Tianlin would only be more dangerous than the golden eagle dragon.
It stands to reason that with the strength of the Red Pupil Tianlin, it is impossible for Jing Chiyang to escape under its eyes, but thinking that the brute dragon and the golden eagle are equally powerful, and even the divine soul breath is not weaker than hers, but the speed has not changed beyond the threshold of the Mahayana period, so Li Dai combined to guess that their own strength is indeed very strong, and even they have no power to resist at all, but they are in this thunderous and barren world, whether it is strength or cultivation, it is as if they have been suppressed to death, this situation, this situation is like the upper realm immortals coming down, except for their own physical strength and divine soul strength have not changed, the strength that can be exerted is greatly limited, and they cannot use the strength beyond this realm, suppressed by the Heavenly Dao.
And this barren world of thunder, the feeling given to those few big things, is the same.
What exactly is the reason for that?
Could it be that this Thunder World also has a Heavenly Dao, which specializes in suppressing those desolate beasts that seem to be left over from ancient times?
That's right, whether it was the brute dragon, the golden eagle or the red-pupiled Tianlin she hadn't seen, Li Dai was very sure that it wasn't something that could appear in the cultivation realm today, maybe they were by mistake, through the Thunder Sea of Sky Island City, when they entered the Thunder Center, they were pulled into the other space by something.
This is the world of thunder, but it is likely that it is no longer within the scope of the sea of thunder.
Li Dai guessed herself, and Jing Chiyang was stunned.
"This, how is this possible?" but calming down, he added: Your analysis is not unreasonable, speaking of which, it took me a lot of effort to discover the secret of entering the center of the Thunder Sea, if you didn't enter the channel whirlpool after the Purple Thunder Cloud Mushroom Waterfall with your companions, which led to the dispersion of others, it was a matter of time, then I was different, I was originally entered with everyone, there was no time difference, but after entering, I also felt it for the first time, behind the Thunder Waterfall of the Purple Thunder Cloud Mushroom is a rich thunder whirlpool, those thunder whirlpools, should be the entrance to the thunder pool, so everyone is sucking in along the whirlpool, but I was pulled by a force in the middle, pulled away from the whirlpool, and was separated from everyoneγ β
"Now Li Daoyou, you said that you were also pulled over by a force, so the question is, what kind of force, or what is it, that pulls us into the thunder world of this different space. β
"And Li Daoyou, have you noticed that the thunder here is a hundred times more terrifying than the thunder world, it stands to reason that with our strength and physical strength, there is no way to survive when we come in, and it can be split into ashes and annihilated in just a moment, but why, those thunders hurt on me, and those fires fell on me, but they didn't kill me, I never understood this. β
Li Dai was also shocked when she heard this.
She had discovered before that the thunder and fire in this barren thunder world were indeed comparable to the thunder of the destruction of the world that she had experienced, but the thunder of the destruction of the world was so powerful, she had deeply experienced it, if it wasn't for the fact that she had comprehended a little bit of the destruction of the world by mistake, and forcibly urged a sword with her own life, she might have been split into powder in an instant, and now in this world of thunder, if the Tao is as fierce as the thunder of the destruction of the world, then even if she runs the "Half-Demon God Decision" refining body no matter what, it will be useless.
At first, she thought that she was powerful in refining her body, and the thunder in this thunderous barren world looked fierce and paper tigers inside, but now it looks like that is not the case at all.
Can there be an ancient thing like the barbarian dragon red pupil Tianlin, and Lei will be a paper tiger?
Impossible, absolutely impossible!
Thinking of the brute dragon chasing her, although the speed is not fast, it is a sturdy and fierce ancient beast, even if it is a hundred, she can't break it now, so she didn't think about fighting directly, and fled.
Taken together, she and Jing Chi Yang were both pulled into the thunder world of another space by inexplicable power, and although the big thing chasing them was fierce, their speed couldn't keep up as if they were suppressed by something, and whether it was the golden eagle or the brute dragon, they all lost their minds, and their strength and speed were suppressed.
Because Li Dai herself has the space of the New Realm, which can also be said to be a small realm where living creatures can survive, so Li Dai understands very well that in order to suppress any living creature in the small realm, it must be her master, or the new spirit, they are equivalent to the Heavenly Dao in the small world.
It's just that the small realm belongs to the master, not an independent world, so they can be said to be the Heavenly Dao of the small realm, but they are not the real Heavenly Dao.
No matter what the world, the true Heavenly Dao will not be a certain person or a certain spirit, it must be the Dao rules derived by the small world after it is out of the control of humans or spirits, in order to be regarded as the true Heavenly Dao.
In the cultivation realm, the more complete the rules of the Heavenly Dao, the stronger the Heavenly Dao, and the higher the world level.
And the simpler the rules of the Heavenly Dao, the lower the world level, and the more restrictions there are on the monks.
This is also the reason why it is easier for monks in the higher worlds to comprehend the rules of the Great Dao.
Because the avenues of the higher worlds themselves are numerous, much more, and more complete than those of the lower worlds.
From this point of view, the more Dao is a complete world, the higher the level, and the stronger the cycle of world power is relatively speaking, so that the world's spiritual energy is sufficient, there are many spiritual objects, and there are many Great Dao rules, and it is easier to touch some Great Dao rules, which is also the reason why high-level world monks cultivate much faster than low-level world monks.
Not to mention those, but one thing Li Dai knows is that if a world wants to derive the Dao of Heaven, it must have at least nine elements such as gold, wood, water, fire, earth, light, darkness, time and space, which are also the nine basic elements of the world.
With gold, wood, water, fire and earth, you can derive wind, thunder and ice.
With light and darkness, there is aura, demonic energy, and evil energy.
That is to say, heaven and earth form aura, purple qi, haoran righteous qi, etc., and any positive energy gas is inseparable from the light element.
And any dark aura, such as underworld, yin, ghost, demonic, and evil aura, leaves the participation of the non-dark element.
Any world is not black and white, the light element can bring a lot of positive things to the world, and the dark element is also indispensable.
As for time and space, that's not to mention.
The time of any world cannot be fixed, without time, everything is like being frozen, and there will be no growth and change, which shows how terrifying the world without time will be.
If there is no space, the world will be nothing, just like at the beginning of the formation of the world, everything is chaotic, and nothing can be there.
Speaking of which, Li Dai's New Realm space has nine basic elements, which is the reason why the Holy Weapon Space is more advanced than any other space.
The advanced is here.
The holy space has left its master, and without its master, then after countless long years, it has nine basic elements, and it can completely derive the Heavenly Dao by itself, and can form a complete world.
With the nine basic elements, it can only be said that there are the necessary conditions for the formation of the debut rule of the world, but it may not be absolutely formed, maybe the nine elements, one aspect can not be balanced, or the balance is lost, then there will be no way.
If you want to compare the world to a human being, then the nine elements are the formation of human basic cells, through which they continue to grow and evolve, and more cells are transformed into human beings to grow.
As for how far to grow and what to grow into, it depends on time and environment.
In this way, the lower world can also be said to be the early childhood of man, the middle world is the childhood of man, and the higher world is the maturity of man.
Adults are stronger than young children, and the higher world is naturally stronger than people.
It's just that people are born, old, sick and die, in fact, on the whole, the world also exists.
When a monk destroys the environment of a certain world to the extreme, it will cause the world to enter the aging period early.
It is also the cycle that the world will go through from the beginning to the growth to the strength to the destruction.
So, strictly speaking, any world is destroyed, and it may be destroyed by external causes, or by its own causes.
It's just that from the formation to the destruction of a world, if there is no external reason, it only has to go around by itself, which is at least hundreds of billions of years as the base, and it has been proved that even a monk can hardly see the whole process of a world from formation to destruction.
Not to mention those, since the formation of the World Dao Rule, the formation of the Heavenly Dao requires the nine basic elements, then in this thunder world, only a rough induction, it is impossible to have all the nine elements, at least the water element, the wood element, and the earth element.
Therefore, this Thunder World cannot be regarded as a real world, and it cannot have such a thing as Heavenly Dao.
There is no Heavenly Dao, so what is it that suppresses the strength and cultivation of the Barbarian Dragon Golden Eagle?
This reminded Li Dai of the force that had pulled them into here.
If it pulls them in, or it can be seen as some powerful being, then it must have a purpose in pulling people in, so their lives should be safe and not dangerous until it achieves its purpose.
Otherwise, don't talk about the brute dragon and the golden eagle, even the thunder comparable to the destruction of the world made them annihilate in an instant.
That being the case, among so many people, why did that powerful existence choose her and Jing Chiyang?
Does she have anything in common with Keike-yang?
Li Dai frowned, and told him his analysis and imagination again, and Jing Chiyang was shocked.
He can't be blamed.
It's really Li Dai's reasoning and analysis ability that is too strong.
What Heavenly Dao does not exist, what powerful existence, what they may have in common, what their lives will not be in danger for the time being, how did she come to these conclusions?
But after listening to her words, he actually felt that it was very reasonable, too reasonable.
Although he couldn't think of going to the World Heavenly Dao at all, Li Dai not only thought of it, but also ruled it out.
It can be said that in the Jingxing Chamber of Commerce, everyone praised him for his intelligence and knowledge, but now compared with Li Dai, he feels that there is no comparison at all.
"What do we have in common?" Although he believed Li Dai's analysis, he really didn't know what he and Li Dai had in common.
"What spiritual root are you?" Li Dai asked suddenly.
"Jin Linggen!" He is also a single Jin Linggen genius with high purity, otherwise he would not be so valued, in the Jingxing Chamber of Commerce, his favored background is one reason, and his excellent talent is another.
"Jin Linggen, I also have it, isn't it because we all have Jin Linggen?" Li Dai guessed.
However, this was quickly denied by herself, "No, if you only need to meet the condition of Jin Linggen, then whether it is with me or those who come in with you, it is impossible for them to be without Jin Linggen." β
"Yes, I also want to say this, there are not a few who follow me all the way, and there are not a few who contain Jin Linggen. Jing Chiyang also echoed.
"So it's not Jin Linggen's problem, what's the reason?" Li Dai frowned suspiciously, looked at Jing Chi Yang of the large version of the doll, and said tentatively: "Can I check your body and check your spiritual root?" No matter what, Li Dai always believed that the problem was still with the spiritual root, but Jing Chi Yang insisted that he was the golden spiritual root, and Li Dai couldn't help but think of his hidden spirit root, the dark spirit root, no matter how many times it was tested, no one found it.
Although Jing Chiyang was puzzled, he still nodded.
He didn't want to stay in this place anymore.
Li Dai clasped his hand, and a spiritual power entered his body, sensing it carefully.
Suddenly, her eyes lit up.
The spiritual power with a hint of her divine sense actually discovered his difference.
It turned out that in his dantian, in addition to the dazzling golden spiritual root, there was also a transparent spiritual root that could be penetrated by divine consciousness.
"That's ......," Li Dai opened her mouth in shock.
Because she didn't know what kind of spiritual root it was, she hadn't seen it.
But her doubts, the well-informed new spirit spoke immediately.
"Dai, that's the Spatial Spirit Root!"
This person actually has a spatial spiritual root!
It's rare to see a million years of good things?
But the problem is that Jing Chiyang has a space spiritual root, and she doesn't have it!
That's not what she has in common with him!
"Dai, you have forgotten that there are laws of space and time in you, which is also the reason why you have mistakenly entered other 'worlds' several times, those 'worlds' have passed through the timeline, like the pair of gods and women you saw at the beginning, like the former Buddha and Shi Yuan, all because you had a first glimpse of time and accepted the rules of time and space. "These memory new spirits know, or because of the memories of the heart demon and the cross-industry sword spirit, maybe others don't know what the little tree in Li Dai's dantian is, but it knows, but the time is not right, it won't tell Li Dai too much.
Li Dai was a little dazed.
She had inexplicably seen the pair of heavenly gods and men millions of years ago, but when had she ever been to the Buddhist Sect and seen Shi Yuan in the past?
Li Dai, who was touched by Shi Yuan, had a little pain in her brain, and couldn't help but hold her head and snort.
"Li Daoyou, are you okay?" Seeing her sudden pale face and extremely painful appearance, Jing Chiyang couldn't help but be shocked.
"Dai, don't think about it, you know there's such a thing!"
Li Dai pounded her head, feeling that she had forgotten something important, but she really couldn't remember, she didn't remember what Buddha sect Xin Ling mentioned, and where Shi Yuan had any past, he had already become a Buddha, and the parting stone he gave himself continued to be completely shattered and lost his Buddha light because of the erosion of countless demonic qi and yin qi.
The place where the Netherworld City is connected dissolves the anger in the Yellow Spring Water.
It was the talisman stone that Shi Yuan parted to her, and he said the same, so if it was broken, the Buddha light inside was used up, and Li Dai didn't think much about it.
She is grateful to Shi Yuan and treats him as a friend, but he has become a Buddha, and there is a difference between him and herself, and friends can't do it, fate is like this, and it can't be forced.
When he is strong, maybe he will be able to help him one day.
Anyway, she wrote down the favor.
Listening to Xinling's words now, it seems that the truth is not as simple as she seems.
"Li Daoyou, Li Daoyou!"
Lian Li Dai kept beating her head, Jing Chiyang was a little worried, why did a good person suddenly do this.
Li Dai took a few deep breaths, no longer entangled in the doubts in her heart, and didn't think about anything, her brain really didn't hurt.
Forget it, sooner or later she will figure everything out, and it still matters at hand.
Speaking of the rules of time and space, Xinling said that she did, and now Li Dai also remembered it.
Speaking of the suction tract, there are indeed so many times, and the impression is clearer that one time she encountered a danger to her life, countless silk of the avenue poured into her body, and her brain seemed to explode and could not be digested at all, that is, at the critical moment, the small tree in the dantian moved, and sucked the excess tens of millions of avenue threads into the small tree.
Therefore, the meaning of the new spirit, the silk of the Tao that was sucked at that time, also has the Tao of space and time?
"That's right, Dai, although you don't have space and time spiritual roots on your body, you can comprehend them, and they are inseparable from Xiao Miao, and although the Tao in Xiao Miao exists and you can't comprehend it now, it can affect it, so you have your own rules of time and space, and it is easier to return to the past and the future or another space. β
Li Dai: "......"
It's not worth rejoicing at all, okay!
"Dai, the little tree is yours, and you also have the laws of the Tao that it contains, so even if you don't have the spiritual root of time and space, you can comprehend the laws of time and space, and if you comprehend them to the Great Perfection, then it is not a problem to go wherever you want. β
Li Dai: "......"
"But the time is better, through efforts from the primeval to the ancient, there are also some people who have comprehended it to the Great Perfection, but the space is different, most of the people who have the spiritual root of the space have no achievements, because to comprehend the laws of space, you must always shuttle in different spaces, and comprehend in the experience! Even if there is a magic weapon that shuttles through space, it is also quite a dangerous practice, who knows what you will encounter when you shuttle through a certain space, and whether your life is in danger?"
"Now the place where you are is a closed thunder space, but there is a little connection with the Thunder Sea, which pulls you with the spatial path rules and the person with the spatial spiritual root in with the help of external forces. β
"If there is no space path rule or space spirit root to add body, then it is very likely that he will be strangled when he shuttles through the space channel, which is also the reason why the monk fights and cannot survive if he is sucked into the space black hole. β
Li Dai: "......"
So thrilling?
From the words of the new spirit, something was also confirmed and a clear conclusion was reached.
One, they were really pulled in by something.
Second, they were pulled in because they had spatial elements and were not easy to die halfway through.
Third, they were pulled in, and the powerful existence asked for them, and they did not show up, but secretly weakened the power of thunder and the attack of the desolate beast on them, so as not to lose their lives.
Fourth, the powerful being may be watching them, and it will come out sooner or later.
The above points Li Dai summed up.
The new spirit also stopped at the point, and said no more.
About this thunder world, about that powerful existence, the new spirit may know something, but it doesn't reveal it at all.
But that's enough.
Li Dai adjusted her emotions, looked at Jing Chiyang's worried eyes, and shook her head: "I'm fine, I suddenly had a headache just now." β
Li Dai knew that with the relationship between the two of them who had only known each other for a long time, he was not really worried about her body, but worried about losing a partner in this dangerous place, someone who could find a way to leave together.
After listening to Li Dai's words, Jing Chiyang nodded and asked again: "But what did you find? What do we have in common?" He really hoped that Li Dai could find any clues in him to more accurately verify all the speculations she said before.
Li Dai did not hide it, and said:
"We all have a spatial spirit root!"
She doesn't have it, but she can only say so, she can't take out the little tree path or something, anyway, the new spirit said that she doesn't have a space spirit root, but the little tree sucks the time and space rules, she can still comprehend them, and if she doesn't have it, it's equivalent to having it.
However, Li Dai is calm, but Jing Chiyang is not calm at all.
Space Spiritual Root?
Even he hadn't heard of it.
Is there such a spiritual root in the world?
What family tested the ancestor when he didn't find it and didn't try it out?
How could Li Dai see it?
If so, has he changed from a single spirit root genius to a double spirit root?
For a while, Jing Chiyang's mind was wild, and countless thoughts flashed through him.
In the end, I thought that because Li Dai also had Xu Zheng, because he had a spatial spiritual root, he could find out the spatial spiritual root on his body.
So I don't have to worry about it.
"But we have a spatial spirit root, what does it have to do with it pulling us in, what does it want us to do?" Jing Chiyang wondered again.
Li Dai frowned, always feeling that she had touched the key, but she didn't.
"What should we do now?" Knowing that he had a spatial spirit root, he had no clue at all, and he didn't even know how to cultivate it.
"Lead the snake out of the hole!"
Li Dai froze, "Since it doesn't let us die and drags us in, then find a way to let it appear, we can only know its purpose before we can leave here!"
Jing Chiyang agrees, but how to lead?
Li Dai already had a plan, looked at Jing Chiyang and said: "Although this is the case, everything is my guess, to lure the snake out of the hole, then we must be in danger, if that powerful thing really does not let us die, it will definitely make a move, it will appear." β
"So we get out of here and take the initiative to find the Brute Dragon Golden Eagle and let them kill us!"
"This ......"
Jing Chiyang was stunned, this practice was crazy.
It would have lured the snake out of the hole, but if her guess was wrong, they might have died.
Li Dai pursed her lips and looked at Jing Chiyang, "This is a big gamble, I guess it's right, the probability of success is ninety, but there is also ten percent that will kill us, after all, speculation is just speculation, maybe the starting point is wrong, this is also possible!"
"Do you dare to participate?"
"It has led to that secret thing, we can leave, or we may be trapped for the rest of our lives. She had a feeling that if they didn't do anything, the powerful beings in the shadows would think that they were useless and couldn't help it, and then it was possible to leave them to fend for themselves.
So even if it's speculation, her intuition tells her that she can't sit still.
"Together, bet!" Jing Chiyang was silent for only a moment, clenched his fists, and made a decision.
In this way, Li Dai also laughed.
If he really didn't try, Li Dai wouldn't be reluctant, but he wouldn't care about him anymore, even if she was an important person in his mission.
After packing up everything, the two of them came out of the cliff cave, and noticed the different environments near the cliff mouth, dry wood, and the smell of nothing, Li Dai was even more sure of her guess.
Maybe she and Jing Chiyang were forced to come to this place, and they were both compared to the hands of that powerful existence.
Those things that were as dry as wood and black were inconspicuous in the purple and thunderous stones, but when you looked closely, they were things that kept out all smells.
That's why those wild beasts didn't find it?
Under Jing Chiyang's puzzled gaze, Li Dai picked up some wood and threw it into the space.
"This is?" watched Li Dai pick up those things, and Jing Chiyang, who didn't recognize them, didn't know why.
"Heavenly Absolute Wood, you know, right?"
Jing Chiyang's eyes widened.
How did he not know!
Legend has it that it can isolate its own smell from leaking, and it can also isolate the outside breath from disturbing its own treasure.
It's just that the Heavenly Absolute Tree was extinct in ancient times, and the monk has never seen the Heavenly Absolute Wood again, and now Li Dai told him that these inconspicuous, long strips of brown and black wood are Heavenly Absolute Trees, how can it not be shocking.
Shouldn't she take all the extinct treasures of heaven and earth by herself and make a fortune in a muffled voice?
"There are so many here, what's wrong with how many pieces do you get, I'm like that kind of selfish person?" Although the Heavenly Absolute Wood is rare and a rare treasure, the monk has one piece that is enough, thinking about taking it out to sell or giving it away, she also picked up hundreds of pieces, although she doesn't know the price of it, she still has the feeling of getting rich overnight.
She didn't plan to be too greedy to pick up the thousands of Heavenly Absolute Trees around this cliff mouth, if she did, the powerful existence that put these things here might tear her apart.
She has cultivated "Soul Refining", and some of the senses of danger in the dark are still quite keen, so after picking up a hundred yuan, she stopped, and at the same time did not forget to remind Jing Chiyang: "A hundred is enough, don't be greedy!"
Jing Chiyang, who was about to slowly pick up all the light: "......"
Li Dai looked at his painful and twitching expression, and the corners of her mouth hooked and couldn't help but be happy.
Boy, can she really tell him that this is the Heavenly Wood after picking it up?
No matter how stupid she is, she doesn't have the luxury of throwing treasure indiscriminately, okay, it's not that she can't finish it anyway, so why not tell him, one more person to take it and let him remember his favors.
If you don't listen to yourself, you deserve to be killed when you are killed.
Although Jing Chiyang was extremely heartbroken, the spirit stones all over the ground flew like that, but Li Dai's smart brain and judgment ability, she would never be untargeted, so after picking up a hundred, he couldn't stop it, and the two climbed up the steep cliff.
Yes, the place where the cliff cave is located is a cliff, but the slope of this cliff is about sixty or seventy, not ninety vertical.
Otherwise, it would be impossible for the cliff mouth to scatter so many heavenly trees.
On the cliff, Jing Chiyang learned from Li Dai, took a piece in his hand, and then continued to move forward.
Don't say it, because of this piece of wood, I haven't met that barbarian dragon golden eagle or anything for a long time.
This also made Jing Chiyang more sure of Li Dai's insight, which was really a heavenly masterpiece.
After some temptation, Li Dai put away the wood, and Jing Chiyang did the same, and it didn't take long for the behemoth that had failed to track them to appear again.
It's still so big and so terrifying.
Jing Chiyang just watched, his legs were weak, and he couldn't help the urge to run if he wanted to.
Li Dai immediately grabbed him, "Don't move!" Didn't she say that she was right to appear in the experiment, and her guess was correct?
The barbarian dragon golden eagle or the red-pupiled Tianlin felt their breath, and they all rushed over frantically, Jing Chiyang was caught by Li Dai and couldn't move, looking at the claws of the barbarian dragon big-mouthed golden eagle that was close at hand, and the falling unicorn flames fiercely closed their eyes and waited for death.
Li Dai was also pale.
She's betting!
If the thing hadn't appeared when they attacked them, she would have immediately knocked Keike into the space.
Well, she's mainly responsible for getting stunned, and Xinling is responsible for pulling.
So Li Dai grabbed Jing Chiyang and didn't catch him, it wasn't his hand that he was grabbing, but the back of his neck.
With her fingers clasped to the sleeping hole, it is not uncommon for people to lose consciousness in an instant with her strength.
She didn't say it at the time, but Jing Chiyang chose to believe her, she also has a backhand, and they won't really die if they lose the bet.
But of course, I won't talk about that.
"Boom-"
"Bang-"
At the last moment, the fireball that was close at hand and the barbarian dragon golden eagle that rushed over suddenly seemed to be frozen by something, and they were thrown out at once.
The huge body touched the ground, and the ground shook and made an earth-shattering sound.
Jing Chiyang, who was so nervous that his heart was beating wildly, quietly opened his eyes and saw all this, as if he was still in a dream.
It's true!
It's true!
They won the bet!
Li Dai's guess is right!
It was the first time to do such a crazy thing, risking my life to get out, but I didn't expect it to really succeed.
Jing Chiyang couldn't help but laugh, laughing so much that tears came out.
"Great, great!" he grabbed Li Dai's shoulder, his face flushed and shook with excitement, and he kept saying "Great".
Li Dai also breathed a sigh of relief and laughed.
"Senior, since you're here, please come out and see you!" Li Dai said to the thunderous air.
