"Play... Tool?..... ”

Yeyun lined up the corners of his mouth, and a trace of black line crossed his forehead

"Wow! The teacher is amazing! ”

Little Ziggy on the side blushed with excitement and wanted to jump up with excitement, of course, provided that his teacher was not by his side.

"Yes, it's a toy。。。。。"

The old man said lightly, casually fiddling with some unknown parts and fragments scattered on the ground around him, some of which could be reused, and some of which could only be discarded.

"Senpai!"

I don't know the name of this old man, Yeyun had to call him senior, pointed to Xiao Zige on the side, Yeyun said neither humbly nor arrogantly: "About that owl, it was me and a friend who killed it, so it has nothing to do with Xiao Qige, and I used the magic core of the red fire lizard as an exchange for the corpse of that owl, I don't know if the predecessor is satisfied?" ”

"Isn't the core already used? What, boy, do you still have it? ”

It didn't seem to care about the owl at all, but when he heard Yeyun's words, the old man asked Yeyun about the demon core.

"Yes"

Yeyun nodded honestly, but he didn't know what the old man was going to do, so he touched Xiao Zige's head and said to him: "There's nothing for you here, go and complete today's training。。。。。 ”

"But teacher, it's past midnight now!"

Little Ziegy replied very seriously, making the old man stunned, and looked back at the magic clock on the wall, and couldn't help but smile dryly, obviously he was so absorbed in experiments that he forgot the time.

"Okay, then you go and rest, I'm going to 。。。。。。 with this"

At first, Yeyun thought that the old man had forgotten his name, and was about to remind him, but found that Xiao Zige hurriedly greeted him, suggesting that he should not disturb his teacher.

"What's wrong with your teacher?"

Walking to the side of Xiao Zige, Yeyun asked suspiciously, Xiao Zige seemed to be used to seeing the old man like this, and said with a frown: "The teacher probably suddenly thought of something related to the experiment, often like this, it was a long time to think about it, and there were several times when the teacher pondered for too long, and fainted directly from hunger。。。。。 ”

As he spoke, little Zigger's nose was sour, and his eyes were misty, and at this moment Yeyun knew that little Zieg was not afraid of his teacher, but that he cared too much about his teacher, and he wanted to do his best in every word and deed, and he didn't want to disappoint the teacher.

As time passed, the two stayed by the old man's side until dawn the next day.

Yeyun is okay, but the little Zige next to him is already angry, looking at his sleepy look, it seems that he can fall asleep at any time, Yeyun let him sleep first, and he is here to watch, but the little guy refuses to live or die, his red eyes widen, and he cheers up his spirits and does not let himself fall asleep.

"This kid 。。。。。。"

Yeyun smiled faintly, and was thinking about how to make this kid go back to sleep honestly, but the old man who was deep in thought suddenly moved his body!

He's waking up?!

Xiao Zieg reacted the fastest, and out of nowhere he brought some test tubes, which were filled with light green unknown liquid, the old man slowly opened his eyes, looking a little tired, Xiao Zige hurriedly handed the test tube forward, obviously this is not the first time.

After drinking the unknown liquid, the old man's somewhat tired face weakened a little, and his pale face gradually regained his flesh color, the old man exhaled, smiled faintly, and felt a lot more relaxed all over his body, it seems that he has gained a good result from this contemplation, probably solving some problems or something.

Turning his head to look at Xiao Zige, he found that his eyes were red and bloodshot, which made the old man have a headache, and hurriedly sent Xiao Zig back to sleep, and then looked at Yeyun with a smile.

Yeyun felt a little weird to be stared at by the old man, but he still looked at his nose, nose and mouth, and mouth, and stood straight aside, the old man saw that Yeyun didn't react at all, but he didn't care, and slowly fiddled with the scattered small things on the ground next to him and said: "Boy, your magic core made me think of something, and I'm glad that I solved the problem of those things by the way, so in return, you, what do you want?" If I can get it, old man, I will give it to you。。。。。 ”

"The Thing of the Owl"

Yeyun knew that the old man didn't seem to care about the matter, but with Yeyun's character, he felt that it was better to figure it out.

"What do you want to know?"

The old man raised his head and looked at Yeyun, who replied expressionlessly, "What is a owl?" ”

"Owls are not things!"

Speaking of the owl, the old man's brows couldn't help frowning, it seemed that he was also a little disgusted with the owl, still fiddling with those things in his hands, but his mouth was unhurried to Yeyun explained: "The owl is a certain old immortal guy in the tower research, at first his idea is that the human brain, that is, the intelligence and the strength and attack of the monster body, create a new human being, but the old immortal seems to have created something wrong, either the person is crazy, or the two are not matched at all and die directly, uh, owl, It is the old immortal who made the test product with the corpse and the demon beast according to the ratio he designed himself, according to what the old immortal said, if it succeeds, then he can successfully transplant the powerful limbs of the demon beast under the complete control of man! ”

Looking at Yeyun's slightly disgusted expression, the old man added lightly: "In the eyes of the world, this kind of experiment is very disgusting, but in another aspect, this experiment can be said to be brilliant!" ”

"Brilliant?"

Yeyun lightly spit out these two words, using people as a test, he really couldn't think of any aspects that could be said to be brilliant.

"War!"

The words are not shocking, and the death is endless! Although Yeyun is young, he doesn't understand anything, war, yes, if this kind of experiment is successful, it is almost impeccable when applied to war! Think about it, in the army, if nine-tenths of the soldiers are junior swordsmen, then only one-tenth of the soldiers are only at the level of intermediate swordsmen, and a great swordsman is generally at the level of generals, but if this test is used on the nine-tenths of the soldiers, then the nine-tenths of the soldiers will instantly increase the combat effectiveness of the entire legion to an unknown number of times!

And Ye Yun, who had personally fought with the owl, knew that the owl could only be solved by a person of the level of the Great Sword Master!

Suppose that a legion has 100,000 junior swordsmen, and after using this experiment, the 100,000 junior swordsmen will all become 100,000 great swordsmen overnight。。。。。。

An army of 100,000 great sword masters! Only those who have personally commanded a war will truly understand what kind of concept this is?!

Even if it was Yeyun, his face showed a hint of shock at this moment, how could he, who had commanded the war, not understand what this number represented?!

Seeing Yeyun's slightly shocked expression, the old man showed a faint smile, it seems that this kid is not stupid, not only that, but he still didn't show much shock when he knew this kind of thing, the old man couldn't help but show a hint of appreciation, this is the second time he has shown this expression of appreciation after seeing this young man.

But Yeyun's attention at the moment was not on the old man's body at all, and he was not thinking about the shocking experiment, but the Six Spiral Towers of the Underworld!

What the hell is that place, and there are such geeks in it!?

Glancing at the old man blankly, although the appearance of smiling but not smiling was not a joke, there was a hint of playfulness, Yeyun frowned, and then thought of some important points!

No matter how huge the Six Spiral Towers of the Underworld is, it is just an organization, it is impossible to compare with an empire, and if the experiment I just thought about is really tried on 100,000 people, it is simply impossible, there is still time required for human and financial resources, people's thoughts, and a series of uncertain factors, 100,000 people are absolutely impossible, but three or four hundred people should not be a problem!

The old man may not have thought that in just a short moment, Yeyun would think of so many things, although hundreds of people still have a terrifying impression of the increase in the strength of the army, but compared to the 100,000 people that Yeyun just thought, he didn't know how much it was reduced.

Looking at Yeyun's frowning brows gradually relaxed, the old man's eyes showed a trace of cunning, and after a pause, the old man suddenly stood up, patted the dust on his body, and said to Yeyun: "Okay, boy, do you still have something to ask?" The old man still has a lot of experiments to do... ”

"Gone"

Yeyun replied very simply, but he kept thinking about this magical castle in his heart, and the skillful skills of exercising his mental power perception ability made Yeyun curious, and these are only a small part of the castle, so what about the rest?

Just thinking about it, the old man suddenly turned around and said to Yeyun, "Are you okay?" ”

"No, it's gone..."

Yeyun replied honestly, Yeyun thought that he was probably disturbing people here, and was about to say goodbye, but he didn't expect the old man's next sentence to swallow his farewell back into his stomach.

"So you have nothing to do? Okay, come and give me a hand and help the old man! ”

The old man looked at Yeyun with a smile, but Yeyun could only see a trace of trance, this old man 。。。。。。

Yeyun suddenly felt that he seemed to have suffered a loss, but he really wanted to stay in this ancient castle, and the old man's words easily left him as a coolie, and he didn't have any thoughts of rebellion!

"Even if it is, let's make it a condition to stay。。。。。。

Yeyun muttered a few words lightly, and didn't know if he was comforting himself, and glanced at the thin old man who looked like a skeleton, Yeyun suddenly realized that this old man had a trace of thinness? He's just a human being! Cannibalism doesn't spit out bones!

"Hey! I said, boy, don't eat rice with me anymore! Get to work! ”

When he turned around and saw that Yeyun was in a daze, the old man hurriedly shouted, listening to his extremely high voice, where was there a trace of weakness? Stunned, Yeyun hurriedly sobered up, and hurriedly began to clean up the messy things underground according to the old man's instructions, listening to the old man's tasks to himself, Yeyun suddenly had an illusion, could he sell it to him?

Time flies, a few days have passed in a blink of an eye, these days, Yeyun has been helping the old man to experiment almost day and night, from trivial sundries, to the puppet directly attacked by the old man, and after a few days, Yeyun is tired and exhausted, but on the contrary, Yeyun's attitude towards the old man is a strong change, if Yeyun is just an old man who is quite successful in the experiment at first, then through a few days of assistance, Yeyun from surprise to surprise, and then from surprise to shock! This old man's experiment, no matter which one of them is taken out casually, is enough to shock the entire Magic Continent! The old man is involved in a wide range of knowledge, ancient formations, new magic innovations, magic amplification defense props, fighting technique theory, energy conversion, space fission, element arrangement, etc., etc., each of which makes Yeyun admire from the bottom of his heart, and through Xiao Zig Yeyun, he learned that this ancient castle was designed by his teacher!

Absolute master, Yeyun has seen a lot of characters over the years, but there are not many of them that can make him admire, and for this old man, Yeyun's heart is not only admiration but admiration.

After many days of sleeplessness, the old man completely relied on the nutrient solution he made to maintain his body functions, and on the fourth day, the old man finally collapsed to the ground after he completed a satisfactory set of energy fusion theory.

Looking at the little Zig with red eyes, Yeyun touched his little head and comforted: "I have checked your teacher's body, he is fine, he just needs to rest for two days." ”

Hearing Yeyun's words, Xiao Zige didn't mean to be happy, held his mouth, held back his crying, and said to Yeyun: "The teacher's health has become worse and worse in recent years, and the teacher told me that the nutrient solution is not a panacea, and long-term use has a great hindrance to the function of the human body。。。。。 Now the teacher is like this。。。。。。 I..... Speaking of the back, little Zieg could no longer speak, his nose was sore, and tears flowed down his face.

Yeyun's expression was a little silent, he didn't speak anymore, touched Xiao Zige's head, slowly walked to the old man on the bed, stretched out his hand to reach out to the old man, and a soft spiritual force slowly output.

In a moment, Yeyun's brows couldn't help frowning, the old man's physical condition was even worse than he imagined! Most of the functions have almost ceased to function, according to common sense, the old man should have been lying in bed all day and unable to move, but he insisted on relying on the support of the artifact's nutrient solution, doing all kinds of research day and night!

With a calm face, Yeyun didn't say anything, but silently reluctantly repaired the old man's "broken" body, which was already Yeyun's greatest ability.

Looking at the teacher's face suddenly appeared a trace of flesh, Xiao Zige almost jumped up excitedly, although he didn't know how Yeyun did it, but he clearly understood that the teacher's body was gradually improving!

Withdrawing his hand, Yeyun sighed secretly in his heart, making the safest estimate, the old man may not live for three years!

He's close to running out of oil!

Glancing back at Xiao Zige, Yeyun didn't intend to tell him about the old man's physical condition, but just touched his head and said lightly: "You have to work hard and increase your strength, so that you can help your teacher and share the burden for him。。。。。。 ”

Halfway through speaking, Yeyun suddenly paused, isn't this what he said to himself? I have to become stronger, so that I can have the strength to help the teacher at night.

Nodding as if he didn't understand, Xiao Zige stayed by the old man's side to take care of him worriedly, while Yeyun walked out of the room silently.

Although he didn't understand the arrangement of the magic elements, Yeyun had a perception crystal similar to half of the pass given to him by the old man, and with this crystal, Yeyun no longer had to practice opening a door, and needed the help of Xiao Zige.

The castle is very large, this is the only feeling for Yeyun, the surrounding walls are quite old, but there is a different taste, Yeyun blindly wandered back and forth between the castles, saying that it was blind, but in fact it was not at all, stunned, Yeyun unconsciously came to the door of a seemingly quaint room.

This room is the only room that the old man is not allowed to approach, and there is no reason for it, but it is not allowed.

Yeyun poked out the slightest sense of perception, but was surprised to find that there seemed to be an energy vortex in the room, absorbing all the energy perception he released!

"Huh?"

Yeyun retracted his senses and was about to leave, but suddenly heard the voice that had been silent for a long time.

Purple Thunder!?

"What's wrong?"

Yeyun asked, for several days, Yeyun didn't hear any of the two swords speak.

"There's a wacky 。。。。。。 in there"

Zi Lei's voice was slightly low, as if he was worried and thoughtful.

"Questions?" Yeyun asked lightly, since it can make Zi Lei feel curious, there must be something wrong over there.

"I don't know, let's go in and have a look。。。。。。"

Nodding, Yeyun stretched out the perceptual crystal, slowly leaned towards the door, and with a "squeak", the door was slowly opened.

Yeyun cautiously walked in, but was surprised to find that the whole room was empty, and there was nothing!

"Over here!"

When Yeyun heard the voice, his calm face suddenly burst for a while, and on the back of the gate, it turned out to be a vortex of energy, and the silver-white light was faintly volatilizing, neither bright nor dim.

"What is this?" Yeyun had never seen this strange thing, and asked Zi Lei suspiciously.

"Magic Array, and it's also a Spatial Transmission Magic Array。。。。。。"

Qiu Longjian, who hadn't spoken for a long time, finally spoke, smiled gloomily, and said with a little disdain: "Why don't you kid even know this kind of thing?" ”
