"I really didn't expect it to be him, it looks like he has collected some information." Xu You pondered for a moment.

Everyone went to the inside of the institute together, and each of them was in a strict and careful mood, but no one felt nervous, except for Xu You, whose palms were a little sweaty.

Everyone else is a veteran in this area, and such feelings have long since disappeared in their hearts.

"Young master, we can't go far and we can see what you need." The muscular man said cautiously.

Cheng An nodded, and the five of them continued to move forward, and suddenly two beautiful female researchers came over, and the disguise of the people was very good, they didn't notice it, and because of this, many people were blinded.

"Wait, what's your name, I think I've seen you somewhere." One of the beautiful researchers stopped, and he felt that Xu You's figure seemed to be seen somewhere.

"It's impossible, you see that they are all hanging special identification cards for the boss's relatives, do you know the relatives of the big boss." The muscular man immediately took off his helmet and walked over to play the round.

"You're not..., I'm sorry, I read it wrong." The beauty was startled, and the two left in a hurry.

Cheng An suddenly became alert, and he felt that this agent was not as simple as an ordinary agent.

"Really, is my face so horrible, I used to talk like a good friend, and suddenly it became like this, it's strange." The muscular man doesn't know why.

The reaction of the beautiful researcher was greatly unexpected by the muscular man, and he looked at his staff card and did not feel like a bad person.

After a commotion, he led everyone to a place that said "Youth Conversion Room" and opened the door with an access card.

The five of them went inside, it was very dark, the muscular man turned on the light, and the room was filled with a lot of test tubes with labels written on them, most of which were written with the former owners of youth and their ages.

Cheng An couldn't wait to bend down and look at them one by one, Xu You looked at the vast dark blue machine in the innermost, he was guessing that these transformations of youth were most likely from the hands of this machine.

"You seem to notice something?" The muscular man closed the door and said with great interest in the aisle.

"This machine must be an important machine if I guessed correctly." Xu You looked left and right, but he didn't dare to touch the button on it, he was afraid that it would trigger an alarm or something.

The muscular man touched the machine, and his eyes looked as cherished as if he were touching his own son's head.

Such a look immediately made Xu You more vigilant, if he didn't work here, how could he cherish the machines here.

Perhaps Xu You's suspicion made the muscular man aware of it, so he coughed kissed and walked over to help Cheng An find his original youth.

Cheng Muzhen and Lin Yuan also went over to help, Xu You looked at the machine and began to study, the buttons on it are all expressed in pattern and Chinese, and even the advanced functions that can simulate the corresponding results if the corresponding button is pressed.

This high-tech has many rare features, but in general it is a valuable machine, and it can even be said that it is the only one in the world.

"Don't even think about moving, raise your hands." Four guards shouted with machine guns.

"What's going on, how did we get discovered?" Lin Yuan was very strange, he looked at the muscular man suspiciously.

At this time, the muscular man was very nervous, he raised his hand to surrender, and everyone did the same surrender action, but everything was pretended, these were simple scenes for Lin Yuan, Cheng Muzhen and Cheng An.

The guard cautiously walked up to their side, and just as they were about to pick up the handcuffs and cuff them for questioning, Cheng An twisted the other party's hand with one hand, and the guard's pistol was immediately aimed at his head, as long as he wanted, the guard's life was immediately explained here.

But he didn't do it, because he was going to use the guards to hold the guards hostage to keep the others safe, originally thinking that he was the fastest one, Lin Yuan and Cheng Muzhen didn't know when, they had already put down all the guards who came over.

But they used kung fu and skills, not guns.

"Everyone's okay." The muscular man glanced at everyone and said nervously.

"It's okay, Cheng An hurry up and find what you need, we don't have much time to evacuate." Cheng Muzhen glanced outside the room, and she said lightly.

Cheng An didn't care so much, Lin Yuan and the muscular man followed to check, the situation was urgent, Xu You also followed to check, I don't know if his luck befell him, he bent his head down, and immediately found Cheng An's youth test tube.

"It's here." Xu You felt that this was simply a coincidence, as if someone had specially arranged it.

Everyone immediately walked over, the muscular man took a look, and then put the test tube in the machine, he clicked a few times, and the machine screen showed what Cheng Anjin looked like before the game.

"That's right, young master, now you can go back to your previous age as long as you stand on the other side of the machine and wait for a while." The muscular man said happily.

"Hurry up and help me switch back." Cheng An couldn't wait.

The muscular man quickly pressed the button on the machine, the machine turned on, Cheng Muzhen immediately closed the door of the room, and the other guards also ran to the "youth conversion room".

The muscular man pressed the button, Cheng An originally wanted to go up, but he glanced at Xu You and nodded at him, Xu You turned around and used the glass of the room door to see the situation outside.

Cheng An lowered his head in disappointment, and then entered the machine.

The door of the machine has been closed, and the muscular man is as fierce as a tiger, and the unknown gas is suddenly released in the machine, Cheng An looked at the muscular man with some fear.

Seeing him make an "ok" gesture, Cheng An relieved himself,

The guard had already rushed to the door of the room, and the muscular man had done a bit of manipulation, and the machine screen began to count down, while he picked up the machine gun on his backpack and prepared to fight the guard to the death.

"Don't do useless struggles, we have at least 30 people here, all of them are elites, you can't beat them, you're still a hero, come out and surrender." A guard was kind enough to persuade him to surrender inside and outside.

"Hmph, but when we go out, people outside will say we're bears." Cheng Muzhen snorted coldly, as the elite of the Flying Troupe, he couldn't even solve such a situation, and his peers would laugh until their stomachs hurt when they heard it.

"Okay, don't talk about it, we won't surrender, as for Cheng An's side... Ten seconds, once he succeeds, we will find a way to break through. Lin Yuan said firmly.

"Since you don't come out, then don't blame me for being rude." After the guard finished speaking, the others opened it with the key.

Lin Yuan and Cheng Muzhen knew that things were not good, and after a while, more than a dozen people rushed in, and the three of them each took out their guns in their backpacks, and the muscular man pointed the pistol at their hard work, youth test tube.

"What do you want to do, just say it if you can, as long as you don't touch our test tubes." Seeing this, a man who looked like a captain of the guard suddenly became anxious.

It took 30 years for the Youth Research Institute to get the hard work inside, and the maintenance had to be very careful, and the researchers were carefully selected and spotless and attentive people to work in this room, and they would not allow any problems with any of the precious test tubes.

"As long as you let us go, the conditions are as simple as that." Xu You said loudly.

"Okay, I promise you." The captain of the guard thought for a moment and said helplessly.
