"Old man, what are you talking about, your organization has studied, tired blood." To be honest, Chang Yuan didn't have much hope for asking the old man, because he didn't know what it was when he invested in his liquid chip, but he knew that it was very valuable. But what Chang Yuan didn't expect was that the old man still knew about the blue liquid that he was most concerned about.

"Well, although I am not in charge of this project, Athena, the fifth person in charge of this project, has a good relationship with me, and I learned about it occasionally when I went to her for dinner." Speaking of this, the old man's old face turned red, "The people in the organization are all independent and have their own tasks, so I don't know much. ”

"Let me tell you what I know, we have arrested a few people in our organization to do ** experiments, let the people who were arrested for the test take strong stimulants, and then keep running until they are exhausted. Then quickly draw their blood, extract, filter hundreds of steps, and finally only get a test tube of light blue liquid, this liquid can penetrate almost any object except glass ceramics, etc., and can be quickly absorbed when it falls on people or other animals, so that it is incapacitated and unable to speak, this non-lethal liquid is very useful in assassination and other tasks, but the experiment was terminated because of the great cost, and the fifth child has complained to me many times because of this. The old man told all he knew in one breath.

"Huh? And this effect? Chang Yuan was surprised that other people's treasures that had to go through so many processes to extract could be secreted by themselves, which was great.

"Boy, but in my opinion you didn't secrete it yourself, have you been feeling tired lately? Think about what changes have taken place in your body and don't leave the details behind. The old man asked with a smile and mysteriousness.

"Huh?" Hearing the old man say this, Chang Yuan was also stunned, he carefully recalled the changes that had occurred in his body since he had a relationship with Chen Mengjie, "Yes, not at all." ”

Since Chang Yuan and Chen Mengjie had a relationship, he didn't feel tired at all, because Chang Yuan's body has been exercising, so he didn't take it seriously, thinking that it was the result of his strong body, but it doesn't make sense that he hasn't felt tired for so long, people are not machines, how can they not be tired all the time.

In addition to this change, Chang Yuan looked at the little thumb of his right hand again, and the traces of being cut by Zhang Mingyu with a dagger were gone. Chang Yuan complained a few days ago that his little finger was bitten by something, and the swelling did not go away for a few days, but now Chang Yuan, the little finger that has recovered as before, suddenly realized that he was using his little finger to store those liquids.

Chang Yuan told the old man about these new discoveries, and the old man's eyes lit up at the moment, and he hugged Chang Yuan and said, "Boy, you have picked up a big bargain." ”

Chang Yuan was hugged by the old man, almost out of breath, "Ahem, old man, stay away from me, you want to kill me, why don't I do it." Chang Yuan glared at the old man resentfully, thinking that this old man was too strong, and it seemed that he had to learn martial arts from him.

The old man also realized that he was a little out of shape, but he was also too happy. "Boy, if my guess is correct, the fatigue blood is not deliberately produced by humans, but is a kind of sweat-like garbage that exists in the human body, which can only be broken down by the dormancy of human cells, which is the culprit of fatigue in living beings. Yours is different, your genes are changed so that the cells in your body don't absorb these things, and instead they become storage, which will make you never tired, and you can use these liquids as weapons. At this time, the old man's eyes were also shining, and he seemed to be envious of Chang Yuan's good experience.

"So good?" After listening to the old man's analysis, Chang Yuan was naturally overjoyed.

"But don't be happy too early, you still have a lot of shortcomings, you still have to work hard, don't think you're awesome, I've already told you, this kind of thing organization also has." At this time, the old man looked very serious.

"You have to cut your hands with this liquid, which is not good, the utilization rate is low and dangerous, what should I do?" At this time, the old man lowered his head and muttered in a low voice, not knowing whether to talk to Chang Yuan or to himself.

Chang Yuan didn't care about the old man, and after learning about his ability not to get tired, Chang Yuan's first thought was that he could quickly quench his body.

So for the next 20 days, Chang Yuan ran and did push-ups in the morning, boxed and punched sandbags in the afternoon, and took a medicinal bath in the evening. Because Chang Yuan doesn't feel tired, he always performs these exercises at a sprint speed. And people who have seen Chang Yuan's training thought that Chang Yuan was crazy at first, but in the end, they were all admired, and they insisted on training so desperately, what about those professional athletes.

In such high-intensity training, Chang Yuan's body has become extremely tough, and the eight-pack abdominal muscles on his chest are sharp and angular, and they are very toned.

The quenching foundation that others must spend several years to complete, Chang Yuan miraculously completed it in 20 days, which also surprised the old man, thinking that this was still the foundation that he had worked hard to build the foundation back then? Is this kid pirated, but it can be seen from Chang Yuan's dark skin and angular muscles that Chang Yuan has obviously completed the quenching, and he is stronger than he was back then.

"Well, the kid is good, you can see from the tired blood of this jar that your kid has not put in much effort." The old man took a porcelain jar about 30 centimeters in size and said to Chang Yuan with a smile.

Because Chang Yuan was training and quenching his body almost never dead or alive, he would feel his little thumb swell badly in almost two or three days, and too much blood from fatigue would be produced. Because the blood of fatigue does not corrode porcelain, he prepared a porcelain jar to hold these things, after all, this is also a good thing that is difficult to buy.

"Don't talk nonsense, old man, see if you can practice martial arts now, will you build a solid foundation this time?" The rapid completion of the foundation building made Chang Yuan also more confident, he used to think that no matter how hard he tried, he would not help the old man, although he also worked hard, but the level was too bad after all, and the rapid completion of the foundation made him full of energy again.

"Well, it's okay, which one are you going to practice first?" The old man asked.

"Let's practice it all, and finish it in ten days." Chang Yuan said at this time that in his opinion, building a foundation and quenching the body is step by step, but technical things can be understood, and he has the ability to never forget, so there should be no problem.

"The kid is arrogant." Hearing Chang Yuan's words, the old man was obviously very angry, he had never been so angry with Chang Yuan, today when he heard Chang Yuan's words, he suddenly felt that Chang Yuan was too crazy, he suddenly realized that he had misunderstood Chang Yuan, Chang Yuan was just a calm person on the surface and impetuous in his heart.

Of course, Chang Yuan said that ten days has its basis, and his ability to never forget can allow him to simulate the scene over and over again in his mind, and the analysis and explanation of brain images can make him understand more thoroughly. When he found out that he had this ability, Chang Yuan had already realized that what it lacked was a pair of easy-to-use bodies, it was precisely because he didn't know when he could complete the quenching so he had no confidence, and now, Chang Yuan had completed the quenching, and the things in the disc were the feeling of entering the computer for him, and the learning of martial arts could be completed in a dream, which was naturally not difficult.

"Master, please calm your anger, old man." Chang Yuan didn't call the old man at this time, and said to the old man seriously: "I am not a frivolous person, you know, I am willing to accept your old man's exam in ten days, but the exam is not enough, let it be disposed of." ”

The old man's anger was also a little less at this time, thinking that through such a long time of observation of Chang Yuan, he was not such a scoreless person, this time since he said so, maybe he had his own reason, after all, Chang Yuan could not look at him with the eyes of ordinary people.

The old man exhaled a breath of turbidity, "Okay, there is a task to do in fifteen days, and it will be handed over to you directly at that time, the task is not difficult, and the time has been extended for you, so it will be regarded as a practice of martial arts, and it will be impossible to say if it is completed or not at that time, okay?" ”

"Well, okay, I'll go." Chang Yuan said firmly.

The old man also smiled at this time, this person must let Chang Yuan see it, if he goes by himself, the goal is too big, and it will be easier to have problems if he brings him back to see Chang Yuan, so let Chang Yuan go to see him directly, killing two birds with one stone. The old man secretly thinks he's smart, hehe.
