101.yooooooooo——

"Are you the girl from before? So you were all in disguise......

The man took a posture of wariness, but only he could understand the incongruity - judging from the other party's behavior alone, whether the other party was proficient in martial arts or magic, he did not have any intention of making a move, but this defenseless relaxed posture made him feel like he was on pins and needles.

It seems that every step that the other party takes is just stepping on the rhythm of the heartbeat. As the other party got closer and closer to him, the man felt that his heart was about to jump out of his throat......

But his body kept emphasizing to his master, whether he attacked or retreated, it was now meaningless - the man didn't want to leave, the warning signals in his brain came and went, but no matter how hard he tossed here, Xiao Yujun refused to carry out the order, and he didn't have any way.

Where the hell did such a dangerous person come from?

The only thing that made the man feel fortunate was that the mysterious girl had stunned the girl before she appeared, and it didn't look like she was going to kill them all. But this thought was immediately suppressed by the man - there was no hostility towards those two young people, it didn't mean that she was willing to let herself go!

Aisha walked over to the fainted girl, picked up the medicine bottle that had fallen on the ground, picked it up and looked at it carefully, and then looked at the man with a strange expression.

"Phoenix blood, what a luxury guy...... However, this medicine is too sloppy, and it is simply based on the nature of the phoenix blood itself, right? It's like diluting the phoenix blood with water - but anyone who understands some pharmacology and alchemy can't waste materials like you. I say. You can't be a phoenix, right?"

Otherwise, no matter how extravagant and wasteful it is, there is no reason to squander such a rare and rare phoenix blood......

The man secretly said that it was not good, and he couldn't help but complain in his heart why he was nosy before. So that the identity that is now hidden is detected...... Thinking of this, the man's eyes couldn't help but become fierce. Seeing this scene and reaction, Aisha also understood that she should have poked at the man's secret.

"Eat it, remember to eat cleanly. Although Aisha's identity surprised Aisha a little, it was only to the extent of "that's all" - on the contrary, because of the man's hidden identity as a phoenix. Aisha was going to be ruthless. After all, the other party is disguised as a human being, obviously not wanting his identity to be revealed. Conflict is inevitable.

Aisha gave a command into the empty air, and the man, realizing that something was wrong, was about to flee, but was shocked to find a sharp pain in his hands and feet. And at the same time, I couldn't move! That feeling...... Perhaps a very foreign experience to most humans. But as a phoenix, before he took on a human form, he often tasted this pain in battle.

It's the pain of being bitten by a creature with sharp teeth!

Although he couldn't see anything gnawing at his hands and feet, there was no doubt that the small "rattle" sound that reached his ears was a sign that the bones were being crushed by a creature with a huge bite!

With a scream of pain, the man's hands and feet were torn off by the invisible beast...... However. In this cruel picture, there is no red in it. Let the long-prepared Mosaic Jun also be stunned.

The section of the torn body did not show any human anatomy at all, and there were no muscles, no blood vessels, and no bones—almost at the moment when the man was torn apart, the limbs that left the torso turned neatly into a ball of fire. And the torso part was also ignited with flames, and in the blink of an eye, the body part that had become a human body was engulfed by the ferocious flames.

This was not unexpected.

The phoenix is best known for its almost eerie vitality. They have a rather magnificent and glamorous appearance, but many people are puzzled about whether the phoenix should be planned into the concept of "life" - it is hard to say whether there is any life that is more "scattered" than the phoenix.

Death is the meaning of the end for most lives, but for these phoenixes, it has lost its binding force. Aisha said that she still needs thousands of years to wait for the CD, and this group of undisciplined creatures can directly reverse Brother Chun on the spot, this unmagical vitality, even if Aisha knows it, but thinking about it is still a mouthful of blood.

Of course, even the shorter methods can cure these guys, but it is undeniable that there is only one race that can treat life and death as ordinary as eating jelly beans (note that it is a race, not an individual).

Anyway, for Phoenix, "die first" is often used as a preparatory action for a counteroffensive......

Aisha quickly defended herself, protecting herself and the man and woman behind her—and then a violent explosion swept away, faintly mixed with a few whimpering sounds of pain amid the explosion. The wind elemental creatures that were called out by Aisha also ate this one firmly because they didn't have time to react. Although they are strong enough in their own right, the flames of the phoenix's self-explosion are not something that ordinary people can catch.

At the very least, there must be some pain.

Aisha had set up an enchantment around her before, and there was a lot of noise in this small alley, but it didn't make people outside feel a little strange.

"The action is a lot quicker than expected, but the self-detonation attack just now is a little weak, is it my illusion?" After waiting for the smoke and dust to clear, Aisha was surprised to see a small phoenix lying on the ground in front of her - the phoenix would lose consciousness after the self-explosion?

Wait a minute...... Noumenon?

Aisha turned sharply to look behind her, and with her powerful vision, she still caught a gray in the distance, turned around the corner and disappeared.

“...... Fooled?"

Aisha rubbed her forehead helplessly. She didn't want to make the relationship too stiff at the beginning, so she still left room when she started (although this is already a ruthless level for normal people, but after all, the other party is a phoenix). But I didn't expect that I had a misunderstanding at the beginning. As a result, it left him with a chance to escape.

I always feel a little out of shape - just now I was played by a ghost. This made Aisha's heart even deeper, as if it was reminding her that the omission she had a premonition was a sure thing.

That's right, the one who confronted Aisha just now was a ghost.

"This little phoenix is not dead...... Hmm? When the soul of the original body still exists, can the dove occupy the magpie's nest? I really should have left him to ask him just now. ”

Aisha took a closer look. It was found that the little phoenix that looked like it had "fainted" was really just a "coma" and not a soulless corpse! This little guy is not yet an adult, and it is no wonder that after the mysterious ghost escapes, it will be resurrected in the form of its main body - this little phoenix obviously does not have the ability to transform into a human form.

"This touch of porcelain is really speechless......"

Originally, Aisha just wanted to take advantage of the opportunity. Dig into the other person's mouth what he wants to know. By the way, save the two traversers who gave her a good impression. But now, what she wanted to know most about the strange girl was that she didn't get any information about the strange girl, but she had to piggyback on a small trouble—if it was a person, then Aisha would have thrown it everywhere, but this is a phoenix! Even if it is still relatively small, it is still a phoenix, and it is impossible for people to see it without causing a big trouble and a big sensation.

In desperation. Aisha could only sigh and let the magic array envelop the little phoenix's body as well.

===================

It's horrible.

After escaping from the imperial capital in a hurry. The unknown ghost stopped his tracks, made sure that the palpitating woman was not chasing after him, and finally relaxed.

With the help of the self-explosion caused by the phoenix bloodline, it obscured Aisha's senses in an instant, and at the same time shook off and repelled the four elemental beings that had bitten his body—although it didn't react when it was attacked at first, but under the light and heat impact of the self-explosion, the originally transparent and invisible wind elemental creatures also exposed their traces. And the ghost's eyes are also very poisonous, and they almost immediately distinguish the identity of the other party!

It was a high-level mage who communicated with the elemental plane before he could summon elemental life to the present world.

But that's not the point – the point is that under the suicidal attack of a phoenix, they actually only felt a little pain and barely suffered substantial damage!

You must know that the phoenix is certainly very famous in the aspect of rebirth from the fire, but its flame has a very strong demon-breaking attribute, which is also known to the world. Elemental creatures are not inhabitants of this worldly realm, and they are more afraid of the power of the phoenix flame, which has the effect of dispelling and purifying, as they have been able to appear in the world with the help of magic contracts. And if it was a phoenix's suicide attack, the amount of power that bloomed in an instant was enough to wash away the traces of elemental life in the present world.

However, the other party was not affected at all, and this intensity frightened the ghost.

It may not have reached the level of the legendary elemental lord, but those four wind elemental lifeforms are definitely the best of their kind, and I believe that even in the plane of the wind element, there is a place for them!

And the mysterious woman who was able to freely drive four such powerful elemental creatures at the same time, no matter what she thought, the amount of power she hid made the ghost spirit deeply afraid. Although it was very sorry for the loss of that incomparably excellent body, it was fortunate to be able to survive in front of that kind of monster when it thought about it.

The ghost has no intention of finding a place - he was able to escape this time, largely because the other party was afraid of his identity and did not act too ruthlessly, but now he knows that he is a dangerous existence that occupies other people's bodies...... The ghost remembered the other party's performance at the time, although he was not full of justice and was a little vague, but he was definitely not a person who followed crooked paths. What will happen to himself, who has almost been labeled as "evil", if he is touched again, the ghost feels that there is no need to delve too deeply.

"It's just...... It's still a pity, after all, it's a phoenix......."

For such a change, the ghost is also helpless.

So. His own plan is completely in vain. To make matters worse, today's situation is almost equivalent to the loss of all three "keys" - those two have been controlled by themselves. Now it should be in the care of that terrible woman, and the cunning little girl who was tracking down herself is completely gone.

Thinking of this, the ghost suddenly felt a depression in his heart.

"But...... Even if that 'adult' escapes from the predicament, will I really be free?" However, its actions were originally spontaneous. It's just a whim to earn more "credit", because there is no explicit order, and there is no need to worry about being punished.

Otherwise, where does it have the leisure to be "sentimental"?

"The only thing to be thankful for. At least all three of them are already here. My actions didn't add to the overall situation. For the sake of that 'lord', I can only wronged you to make some sacrifices...... Hmph, anyway, most people are just that kind of virtue, and it's not a pity at all. ”

As for the few exceptions to the "quality" that may not be up to standard...... Thinking of the cunning girl he was chasing, and the girl who looked like his sister in the past, the ghost couldn't help but wonder - wasn't it a group of young men with not very good personalities, how did they get into two girls, and besides, not to mention a very weak and kind fool, even the girl who had run away. When I first saw him, he was also dressed as a papal ascetic and helping two old men...... In terms of personality, it seems to be a lot worse than the standard.

If it weren't for the fact that they were not the inhabitants of this world, it was confirmed. The ghost really just looked away.

"But what do I want to do now? Just my powerless appearance...... Forget it, let's find a body first, at least we have to restore the mobility of normal people first. ”

Although he also has combat power in the ghost state, he still knows very well that there are many things that he can't do as a ghost who seems to be full of evil spirits.

=================

After returning to her residence, Aisha also looked at the room that had been "enriched" a lot at once, and couldn't help but feel a little embarrassed - now, do you have to rearrange the room?

Although it is a "little phoenix", when it is really put in the two-person dormitory, which is not very spacious, the little phoenix that sleeps really well takes up a lot of space. Aisha thought about it, and could only put away the desk, dinner table, etc. first, and sorted out an empty area, which was temporarily left for the little phoenix to nap.

Then the young man was thrown directly into the utility room by Aisha. In the previous chance encounters, he did perform quite well, at least not ugly, but based on the "selection criteria" revealed by the fragrance, Aisha still doesn't trust some aspects of the character of these male traversers - maybe because this kid met the girl he liked, and the life of stepping into the other world was quite difficult, which led to a slight change in personality, but Aisha believes that this transformation will still take some time to complete.

Before that, I can only grieve this kid...... Of course, even if he becomes a good young man, he will still be the fate of being thrown into the utility room by Aisha, but at least the methods will not be so rough and casual, right?

The young man's head seemed to hit the wall, and there was a dull knocking sound, which caused the young man, who was already unconscious because of the beating on his head, to be hurt a second time in the coma - well, if he woke up and had doubts, he would have pushed it on the ghost.

As for the girl...... Aisha thought about it, but was ready to leave a bed for her.

After all, it's a girl, and it's pitiful to suffer so much. (Young man: Am I not pitiful!?

Aisha picked up the girl, intending to change her clothes and clean her body. Looking at the girl's flat chest, Aisha couldn't help but feel a little proud - oops, oops~ It's really an unforgettable youth~

Aisha couldn't help but think of her "childhood", and she often mocked ♀ her three sisters with delicate curves about her tablet-like chest. Now she can also "despise" the poor people's bourgeoisie ♂ ♂ ♂!

Especially after Sister Wei became Xiao Wei, not only was she teased, but even her assets ♀ were gone. Thinking about it is a burst of revenge-like pleasure! Thirty years in Hedong and thirty years in Hexi - eldest sister, you also have today!

"Well, the skin is a good place to be raised, right...... Not to mention, seduce that kid's soul. Not surprising. ”

The girl is not the kind of beauty who sinks into the fish and geese, and in all fairness, the girl's face is still a cut away from that level. However, the feeling of softness and weakness on her body is believed to easily arouse men's desire to protect, right? In addition, the girl does not wear makeup on her face, but looks very pure without makeup, for male compatriots who are in the second stage of secondary school and instinctively dislike "vulgar powder". The attraction is really not small.

But how did such a good girl get here? Aisha couldn't help but wonder a little according to the selection criteria. Whether it's gender or personality, it's more than 108,000 miles worse?

"Well, let's wait for her to wake up and ask about the situation, now ...... Huh?"

Aisha's body froze.

Because I was going to wash the girl's body. Aisha is undressing the girl. When she took off the girl's simple dress, which was a little harsh. Suddenly, the hand touched a place that it shouldn't have touched.

As a woman, and at the same time a self-proclaimed "elder", Aisha doesn't think there's anything wrong with undressing a girl without evil thoughts - but the problem is that it's something she shouldn't touch......

It's not an ethical question, it's absurdity on a scientific level......

"I'm rubbing, why does this kid have Ou Jinjin on him!?"

Aisha immediately took a few steps back in fright, and slammed her head on the sink.

After receiving a blow to the head, Aisha, who was already injured on her body, immediately felt a chaotic feeling in her head...... But that's not the point!, she shook her head immediately. Drove the cluttered thoughts out of the brain and focused the mind. He once again turned his gaze to the smooth skin of the "girl's" abdomen, and then, his gaze moved a few centimeters to the bottom......

"Isn't this the Armstrong Armstrong Boom Boom Boom Boom?

Aisha's brain is in a state of chaos!

Facts speak louder than words - Aisha clearly saw that below the "girl's" lower abdomen, there was clearly a mysterious bulge ♂ on the fat body!

"I ...... I even touched it just now—even though it was a fat time, but I still touched it!

It seems that the management ability of the organization where Fang Xiang used to stay is not too bad, at least the gender of this child is not wrong...... It's better to get both wrong!

Aisha, who was greatly affected by her spirit, powerlessly summoned a simple water element and gave it to the female ...... After the boy gave it the task of bathing, he stroking his headache forehead and staggering out of the bathroom. As soon as she walked a few steps, she saw the young man who had been thrown into the utility room by herself, struggling to get up from it in a daze.

Are you awake? But I still don't seem to be clear......

Seeing this, Aisha did not hesitate to stop the young man's intention to "get up", and "kindly" made the young man fall into "sleep" again with an elbow.

"I can't be the only one who has a lower SAN value!I remember that this kid has some thoughts about that child......" After thinking of the previous performance of the two, the corners of Aisha's mouth couldn't help but rise - her own happiness, although it does not have to be based on the pain of others, but looking at the appearance of this young man who is entangled in pain because of this kind of problem, I believe it must be a very pleasant experience~

"Hehehehehehe......"

Aisha, Aisha, you're smiling like a ghost......

====================

My name is Extreme Wind...... Hah? Ask me why I have such a strange name as a man of the Celestial Empire? Stupid! Since they have all crossed over, in this Western-style fantasy world, do you still use the name that sounded earthy in the past? Even if you change your name, you can pronounce the first and last name of the Chinese name in reverse, and it sounds strange no matter how you hear it—then it is better to simply give it a name that is more like a code name without a surname! It sounds like a chivalrous man who has wandered the world! Really, this has to be asked...... Laughed.

Understand?

But it seems that my character is not very good.

Isn't it true that after crossing over, you are usually in the deep mountains and old forests, and there are harmless little wolves (aborigines collectively vomiting blood) around you to practice your novice skill proficiency? There's also a peaceful newbie village, right?

And the most important thing is - as a traverser, shouldn't it be a simple, beautiful, kind and lovely girl who wakes up her comatose self? The scene is either sunny and fresh green grass and blue sky, or a dim candlelight but kind and warm medicine shed...... As soon as I opened my eyes, there was a fierce middle-aged man in front of me!

And what's going on with the dungeon!?

Did I cross over to the continent of Tamarel?Ah, it suddenly occurred to me that this was not bad - I didn't wake up, surrounded by snow, and I was in a carriage, surrounded by prisoners tied hand and foot, one of whom was still blindfolded...... It's great! As long as you don't have to face the double death test of beheading and dragon roar!

But soon I regretted it.

Whether it is dropped by a knife or casually lit a torch by Mr. Ao, I believe it is just a fleeting pain - people are inherently dead. Or heavier than Mount Tai, or lighter than a feather...... But even if it is lighter than a feather, it is better than grinding and being tortured and not being able to die!

The initial level is too low, no level, no skills, no equipment. As soon as I came up, I wanted to fight the boss battle, this ghost can win! I didn't even give a good time! I grew up in a harmonious society in the 21st century, and I hated slave-like life and treatment -- as a time-traveler, I didn't fight the slave hunting team of the auction textbook, but I was called as a slave!

Of course. It's not that I didn't want to resist – but it turned out. My backbone is as soft as my little friend. Not only did the status of a time-traveler not give me +21 Terra Stone Stick ♂, but it also didn't make me a man who stood up to the sky...... The consciousness that life is worse than death, when you really face the threat of death, it is simply a piece of tissue paper, and you will throw it away after wiping it!

At the end of the day, I'm just a waste wood who likes to surf the Internet and like to daydream.

Do you want to do this? Let me blow the soap bubble bigger and then you pop it...... Before I could even start dreaming, I was woken up by a stick.

Forget it, since the dream is shattered. I'm a wasted person, even if I'm a dog, I can live with a cheeky skin, right? Actually, there's nothing wrong with being a dog. Wagging my tail at least has a meal to eat, maybe one day I will provoke someone I shouldn't mess with, and the owner may not be able to protect me because he is not in the mood to protect me, but that doesn't matter, right?

Anyway, my parents who often nag me are not here, I have no relatives or friends, and I have never been a strong person.

But......

Dogs also have a minimum principle......

Do you want me to help you put pressure on a girl, so that she can't help but sell her life to you, until she is squeezed to the bottom and there is no life left?

I'm just shameless, my conscience hasn't been lost, you soulless!

Just take advantage of the fact that you're still much stronger than me, and give you a good bite - I'll bite you to death before she can't hold it anymore! If I can have the strength to bite your throat as soon as possible...... Damn, even if it's Xiang, I'll eat it!

You wait...... I'll kill you......

You wait...... I'll get you out......

......

"Drink!"

Youth...... Probably calling him the Extreme Wind, he sat up from his bed sweating profusely. He subconsciously looked around - hoping he hadn't been talking in his dreams just now, and wouldn't let that nasty guy hear......

"Eh, good normal room. Extreme Wind looked around, and found a long-lost sunny feeling in this strange room. You must know that since this inexplicable thing, the extreme wind has felt that even on a sunny day, there are clouds on the head. The hateful man, who was full of low pressure and oppression, felt his chest tightness and gasp whenever he was nearby.

But obviously, there was no trace of the man in this room.

"What the hell is going on?" Extreme Wind looked at the room in bewilderment, and saw a large piece of bright red in front of the bed, and when he looked at it, he found that the red was a big bird sleeping soundly...... Then Jifeng clutched the back of his head in pain, and a cold sweat broke out.

It hurts!

Extreme Wind clearly felt a bulging lump on the back of his head. He immediately thought of what had happened to him! The reason why he had fainted was because of that hateful man!

"Damn! that guy ...... Hiss - it hurts......"

Actually, you hurt so much. At least half of the reason is on Aisha - the unknown ghost San only hit you once, but Aisha hit you twice, and the damage output is undoubtedly Aisha's advantage.

"But. Why is that person gone, and why am I here? What is the big bird...... Return...... ...... thing"

The depressed Extreme Wind moved his gaze to his left, and the words in his mouth were like a cassette radio, and after he finished the last two words one by one, he could no longer make a sound.

"Little ...... Xiao Di ......!?Hey!What's going on!?"

Jifeng looked at the figure to his left in disbelief, it was a psychedelic scene that had appeared in his dreams several times - a petite girl (...... He lay on his side beside him. There was a cute and unguarded expression on his face, and he could even feel it from the other party's slightly open cherry mouth. A moist breath that is exhaled rhythmically.

Teenage Girl (...... He was wearing a lovely white shirt with a few buttons at the neckline, and it seemed that the shirt on the left shoulder had slipped off because of the flipping while he was asleep. A section of white fragrant shoulders and delicate collarbones are exposed.

Although the open mouth of the clothes does not allow you to see the next position. However, Jifeng also knows that Xiao Di is a flat-chested (...... ), the charm is not in the career line, but I don't care much about it.

[Oh no! This is the ...... Isn't that tempting me to sin!?]

Jifeng never expected that one day, compared to the more tangled problem of "mother-in-law and girlfriend falling into the water at the same time", he would also encounter - to be a beast?

Jifeng was distressed to find that his little friend seemed to be a little excited...... Yes, even my friends are so enthusiastic, and sure enough, at this time, I should-

"Hmm~-"

Just when the extreme wind is tangled. Xiao Di suddenly let out a lazy snort, and the waist of the extreme wind with a ghost in his heart straightened suddenly. The muscles of the whole body tensed. Of course, the little friend who was excited just now was also poured with a basin of cold water at the moment, and he couldn't get up again.

The wind looked at Xiao Di tremblingly, and found that the other party's eyes were still closed, and although his eyelashes were trembling slightly, he didn't seem to have woken up yet—he just moved his body normally!

Perhaps, it is because she (...... Isn't it because of the mental exertion that you usually have too much? So I slept very hard at this time?

Thinking of this, the last little restlessness in Jifeng's heart was also extinguished - even if the little friend was enthusiastic, it was impossible for Jifeng to do some inappropriate behavior at such a time. If you really do that, I'm afraid that even in another world, your parents will step over the dimensional wall and beat yourself to the point where you can go to Hebei Province to see orthopedics, right?

"Alas...... I can't help it......"

Extreme Wind was a little reluctant to cast another glance at Xiao Huang's face, but as a result, he was once again red by Xiao Huang's defenseless cute sleeping face.

Just hug it, it should be fine, right?

After the last day, Jifeng still chose to give up resistance, pretending to unintentionally hug Xiaodi's arms - two completely different but coordinated smells from his hair and body immediately made Jifeng a little uncomfortable.

[Hey, hey, it's just a hug...... You kid give me a calm!]

After the extreme wind suppressed a burst of evil fire in his heart, he looked at Xiao Di's sleeping face close at hand, and his eyes unconsciously fell on the other party's lovely lips - can you kiss it secretly?

[What should I do?] Is this kind of behavior what it is...... Well, it's just a light touch anyway, and it should be ...... It should be fine, right? yes, just touch it lightly......]

Therefore, men sometimes just like to inch in.

Ah, you are still endless! Is there a follow-up that can be forgiven in this way!? Alas, some men always put the word "cheap woman" on their lips, but in fact, they themselves are not the same virtues......

Just as Jifeng closed his eyes and slowly nervously brought his lips closer, a soft touch pressed against his lips - however, it was not the touch of his lips.

"Oh, no! Anything from then is not allowed!"

"Huh, hey!, Xiaodi, you're not asleep?"

“...... If I'm still asleep, you'll take off my shirt after you put your lips up?"

"Aha, how could it be......" Jifeng sneered and turned her head away, but suddenly thought, since Xiaodian was still awake, wasn't she hugging just now, and she also knew that she was not against that, right?

After having such a thought in his heart, Jifeng's face became obscene.

How could Xiao Di not see what Jifeng was thinking? He had been living with this face for all these years, and he was actually very clear about Jifeng's psychology.

"We can't do that kind of thing......"

"Well, feelings can be cultivated slowly~"

Xiao Di sighed lightly - it seems that it is not possible not to find out, the reason why he tolerated the somewhat obscene behavior of Jifeng just now was only because he had indeed been protected by him a few days ago, and he was grateful that he did not stop it, but further ...... Ahem.

So, Xiao Di opened the box of Pandora, who was the most reluctant.

"Because I'm a boy......"

Xiao Di said, pulling open the sheet.

......

......

"YOOOO......——!!!!!!!OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
