"Gu Tian, can you tell us about the old master's theory of restraint?" Ning Xiu said with a smile in the blink of his eyes.

"I don't know much about the master's theory of mutual restraint, but I have talked to me about some ideas of the theory of mutual restraint, mutual restraint is the surface, and mutual restraint is the inside. Gu Tian smiled and told the three of them about the old master's theory of mutuality, which was mixed with some of his own understanding of mutuality.

"There is no absolute reciprocity, there is no absolute reciprocity, and there is a measure, or a boundary, here. My master once told me that water overcomes fire, but a drop of water can't extinguish fire. In the same way, fire can boil water dry, but water turns into vapor and continues to exist, which is no absolute restraint; wood fire means that wood can help combustion, a piece of wood will not burn itself even if you put it for a hundred years, and a wet wood will not support combustion, this is no absolute mutuality. Gu Tian looked at the three of them with a pensive look on their faces and continued, "Take the battle between me and my senior sister just now, the wind system and the earth system are nothing more than the wind type phantom beasts that can't attack the air type phantom beasts, so I will find a way to make the wind system phantom beasts fall to the ground." ”

"The old master is really a person who asks the Great Wisdom University, and his theoretical conception of mutual cultivation and restraint of attributes is absolutely shocking to the world, but it is a pity that the world is too narrow-minded to recognize the true meaning contained in it, which was originally a creation that can benefit mankind, but was actually excluded from the Taixue Academy, but it is a pity. Ning Xiu suddenly realized.

"Don't worry, sooner or later, one day I will let my master's name resound throughout the entire Gujie Continent. Gu Tian said confidently.

"It seems that one of the phantom beasts I sealed by accident could come in handy now. Ning Xiu said with a smile, "It took a lot of time to seal it. After speaking, Ning Xiu released his third phantom beast.

A body like a green extra-large nut, covered with black spikes with a metallic luster, Gu Tianna aimed the fighter at the target to query information, "Iron Thorn Nut, Seed Science Fiction Beast, Golden Wood Attribute, because it often absorbs nutrients from minerals, its body becomes as hard as metal, and it grows metal-like hard thorns to protect itself, and it can sense a magnetic field to make itself float, but it won't be very long." ”

"Phantom beast of the golden wood attribute, classmate Ning Xiu, your luck is too good. Gu Tian said enviously.

"Originally, it was out of curiosity, but after the seal was successful, I felt that the attribute energy fluctuations in my body were a little abnormal, and after listening to what you just said, I understood what was going on. Ning Xiu withdrew the Iron Thorn Nut and said with a smile, "My fourth phantom beast decided to be a fire or earth type, preferably a dual attribute of fire and earth, hehe." ”

"Are you also planning to take the Xiangsheng route?" Gu Tian asked as he looked at Ning Xiu.

"Of course, how can such an interesting, magical and novel faction have so little of me, the cycle is endless, the cycle is endless, and the true meaning of each other is endless. Right, Gu Tian, classmate?" Ning Xiu said with a smile.

"It seems that you understand it very thoroughly, and I am not alone. But you have to be prepared, this road is not so easy to walk, the road is long and difficult, and the line is coming, we will encourage it together. Gu Tian said with a smile.

Next, the two discussed the application of the theory of mutual restraint and symbiosis in the battle of phantom beasts, and Feng Jiu and Yuan Wei listened attentively and benefited a lot.

"Little junior brother, what's the matter with the attribute energy in your body?" Feng Jiu suddenly asked, "Just now I calmed down and felt it, and there was no fluctuation of attribute energy, this is not normal." ”

Gu Tian smiled and removed the wrench on the thumb of his left hand, and Feng Jiu and the three of them immediately felt that there were three powerful and thick attribute energy fluctuations on Gu Tian's body.

"You...... You have awakened three attribute energies!" Feng Jiu said in surprise.

"Milky white spirit, earthy yellow, orange-red fire. Yuan Wei said enviously, "I only awakened the fire system, but you have awakened three kinds, there is no heavenly reason!"

Ning Xiu looked at Gu Tian's wrench on the table with a curious expression, "It's not that there are no props and equipment that hide attribute energy, but that kind of thing is also a bit useful at the same level and level, once you encounter a high level, no matter how you hide it, you can't hide it, your wrench is not only hidden but hidden, and you hide your attribute energy in the slightest, even the phantom beast master who is higher than your level will not be able to detect it." ”

"Not only the Phantom Beast Master, but even the fighter plane can't check my Phantom Beast information when I'm wearing a wrench. Gu Tian said with a smile as he played with his wrench.

"You can't even look at the fighters. Ning Xiu frowned and said, "Then this wrench can be regarded as a strange treasure, which is quite suitable for you to pretend to be a pig and eat a tiger." ”

"By the way, I almost forgot to successfully challenge the hall master, in addition to the badge and skill scroll. After speaking, Feng Jiu took out two skill scrolls that emitted wind attribute energy from the drawer, "The wind physical attack skill 'Feather Arrow' recorded in the scroll is mediocre, but it is a group attack skill. ”

"Thank you, senior sister. Gu Tian happily took the skill scroll and said, "It just so happens that the Flame Eagle lacks a group attack skill, which is really timely." ”

"Sister Nine, I don't want mine. Ning Xiu said with a smile, "This kind of skill scroll is unlimited, and when I seal the wind phantom beast in the future, I can borrow it directly from Gu Tian, and you should take my one and sell it to make up for it, after all, Gu Tian won a lot of money." ”

"Sister Xiu is still sensible, then I'm welcome. After Feng Jiu finished speaking, he put the skill scroll back in the drawer.

Gu Tian scratched his head a little embarrassed, "I'm poor, I can't help it." By the way, Senior Sister, you want soul beads, I have quite a few here. After speaking, Gu Tian took out the heavy bag from his backpack and put it on the table.

"It's all soul beads here?" Feng Jiu opened the bag suspiciously, and a look of surprise instantly appeared on his face, "There are so many soul beads, although they are all common attributes, but how many phantom beasts do you have to kill to have so many soul beads?"

"Most of these are obtained in the Shuangzhan Canyon, and there should be a hundred or so left after the general department is sold, and I don't know what the value is, and I can't use it now, and besides, the most adventure path is the phantom beast, and I'll collect it again." Gu Tian said nonchalantly.

Feng Jiu naturally didn't say anything polite to Gu Tian, he put away the soul beads with a smile, and in the evening Feng Jiu personally cooked a table of delicious meals, and after eating, Gu Tian and the three of them lived in the Yanfeng Dao Pavilion.

The next day, just after breakfast, there were already phantom beast masters who began to challenge the gym, Gu Tian and the three of them said goodbye to Feng Jiu and continued to embark on an adventure, Gu Tian did not rush out of the city but led Ning Xiu and Yuan Wei back to the Phantom Beast Inn.

"Gu Tian, why are you leading us back to the Phantom Beast Inn, haven't you eaten enough?" asked Yuan Wei puzzled.

"Of course it's for interest!" After speaking, Gu Tian hurriedly pulled Ning Xiu and Yuan Wei aside, and the four of Huowang just got out of the elevator and left the inn after completing the formalities.

"Keep up with them, not only will I get the interest back, but this time I'll be a robber. After speaking, Gu Tianyi waved his hand and motioned for the two to hurry up.

Huowang and the four of them didn't know that they had been targeted, and they went out from the west gate of Yanfeng Town with a joke, and walked for nearly an hour Huowang and the four of them came to a very hidden valley, Huowang took out a worn-out remnant map and compared it carefully.

"Gu Tian, are you going to beat the stuffy sticks? They have stopped, and they want to fight quickly. Yuan Wei said in a low voice.

"What do you know?" Gu Tian glanced at Yuan Wei and said with a sly expression, "I saw that the remnant picture in the grandson's hand is not, there is information about a ruin recorded on it, and when we get to the place, let's cut off the beard, which is the interest of ten antidotes." ”

"Ruins!" Ning Xiu's big eyes showed a light of surprise, and he whispered, "There are good things in there." ”

"Does Ning Xiu know about the ruins?" Gu Tian asked, looking at Ning Xiu.

"Knew a few, but didn't go in. Ning Xiu glanced at the remnant map in Huo Wang's hand and said, "The ruins are a kind of mysterious secret realm left over from ancient times, which is full of unknowns, as long as you can pass the assessment, you will get a reward, and the higher the score, the better the reward." Ruins are roughly divided into three types, one is an exploratory ruins, such ruins are like a maze, you need to grope your way forward, once trapped in a trap or seriously injured, you will be teleported out immediately, which means that you will fail and cannot get rewards; the second is the assistance type, this kind of ruins are the people or phantom beasts in need of help, as long as they help them complete their wishes, they can get rewards; the last is the battle type, this kind of ruins is the most dangerous and the best reward, the battle may be a single battle, or it may be a multiplayer melee, and it may be a large-scale war, it depends on their luck。 Death in the ruins is not real death, but death also means failure, so you must be careful when you get to the ruins! There is also a limit to the number of people in the ruins, some can only enter by one person, and they will disappear immediately after entering, and some are multiple people. This kind of ruins whose location, type, and number of people are not clear are called random ruins, and there is also a kind of fixed ruins, which are very dangerous for large ruins, and if they die inside, they will really die, and each of the eight major cities controls a large fixed ruins guarded by the most elite troops, and some ancient families control small fixed ruins, which is the foundation of their inheritance to this day. ”

"I didn't expect there to be so many types of ruins, I hope we don't have too bad luck and don't encounter a single ruin. Gu Tian said with a smile, "They acted, continue to follow." ”

The four of them circled the valley for more than half an hour, and finally stopped in front of a boulder.

"That's all there is to it, let's look around to see if there's anything special. Huo Wang looked at the remnant picture and looked around again and said.

"Alright, now that we're here, it's time for me to play. Gu Tian smiled and said, "You guys hide and don't move, I'll do this kind of thing myself." After speaking, Gu Tian swaggered out.

"Yo, isn't this the fire of Smoke Town. Gu Tian pretended to have just met him, and said with a look of surprise, "Brother Huo, I just ran out of antidotes, do you still have it?"

"Huowang, do you know?" asked a hoarse voice.

"Yes, it's the stupid hat in Blaze Town who was tricked out of ten antidotes by me. Huo Wang looked at Gu Tian and said disdainfully.

"Why is he here?" asked a muffled voice.

"Don't worry about that, the ruins can't be exposed, drive him away. Said in a thin voice.

"Brother, I'm sorry, I don't have an antidote here, you hurry back to the town, it's not safe in this valley. Huo Wang walked to the opposite side of Gu Tian and said.

"Oh, that's unfortunate. Gu Tian said with a look of bad luck, "What about these three brothers, do you have an antidote, give me a few, one is not too little, ten is not too much, anyway, Brother Fire will pay it back for me, right, Brother Huo." ”

"Why are you so polite to him, get out of here, or I'll let you crawl out!" said in a muffled voice.

"Ahh

"Don't talk nonsense with him, you can't expose it here, grab this kid and tie him up first, and don't let him interfere with us. A thin voice shouted.

"Are you looking for something, I can help you find it!" Gu Tian said with a smile.

"Boy, it's a good thing that you didn't open your eyes and just bumped into us, then don't blame me. After Huo Wang finished speaking, his face turned ruthless, and he punched Gu Tian is fist.

Gu Tian didn't dodge, and he also punched Huowang. Fists collided, Huo Wang screamed, covered his fists and took a few steps back, his forehead was full of cold sweat, and he looked at Gu Tian with a frightened face.

"You stupid, let go of the phantom beast!" a muffled voice shouted.

Huo Wang bared his teeth, stared at Gu Tian viciously, and released a firethorn dog with a wave of his hand.

"One is not enough to see, you all summon phantom beasts, don't bully you when I say it, let's go together." Gu Tian crossed his hands on his chest and looked at them and said coldly.

"He did it on purpose, brothers. Huo Wang looked at Gu Tian's face and changed suddenly, and he instantly understood with a fearless look.

The other three also summoned their own phantom beasts, all Firethorns.

"Pretty girl, come out. As soon as Gu Tian finished speaking, Qiao Limei immediately lifted her stealth and appeared in front of Gu Tian, and Qiao Limei has been in a state of stealth since she came out of the gym and followed Gu Tian, and then Gu Tian also released the sand storm boy.

The four of Huowang were stunned when they saw Gu Tian's two phantom beasts, the four fire thorn dogs were not well cultivated at a glance, and they looked malnourished and listless, while Gu Tian's phantom beasts were a lot stronger in momentum, and after the sand storm boy came out, he just glanced at it fiercely, and the four fire thorn dogs immediately trembled with fright.

"This ...... What kind of phantom beast is this, it can actually float in the air? It looks so beautiful!" The muffled voice asked after aiming the fighter at the pretty girl, there is no way that the sand storm boy is a little similar in appearance to the earth plucking bear cub, where can it be compared to the pretty girl to attract people's attention.

"Didi, sting. "A noisy electronic sound to the fighter plane.

Others also raised their fighters, but the result was the same, "He has something strange about him, when I was in the rookie forest, my fighter had the same situation, and he lied to me that the signal was not good." Huo Wang pointed at Gu Tian and shouted.

"Do you only have Firethorn, release all the phantom beasts, don't say I didn't give you a chance. Gu Tian said coldly.
