While everyone is busy, Fan Mang has left this world again.

In the world of Black, Mib headquarters, Vivier is doing experiments. There is a place she can't figure out, which leads to the genetic medicines she made, which always undergo unknown mutations.

Several people who helped test the medicine have indeed strengthened it, but some have a hand and some have a tail, and no one is willing to use the genetic medicine she developed.

She always felt that she was missing something, but she didn't know what it was. She had obviously used many alien genes, and they were all very similar to those on Earth, but she always failed.

"Vivier, Agent F is back and said he brought back good things."

Have you brought back good things? Vivier's eyes shining.

"f, you are back, what did you bring?"

"A little bit of alien genes and their technical research data will give you a reference. How is your research progress? Can you produce stable genetic agents?"

"It's still one step away. If it goes well, it may be completed in a few months."

Fan Mang curled his lips and said, I will buy the lottery ticket, and if it goes well, I will win the jackpot.

Wei Weier opened the information brought back by Fan Mang, and after reading it for a while, she suddenly stood up: "f, I have a new idea. If I change this gene chain here, I can avoid unknown mutations."

"I'll try it, you wait."

Fan Mang shook his head, it seemed that Vivier had not changed yet.

Just a week later, Vivier recruited some volunteers from Mib.

"Everyone, have you seen these serums in front of you? This is a new genetic agent I developed. It has stronger stability and can theoretically greatly strengthen physical fitness and delay cell aging."

"Although I can't achieve eternal life, it can still be done to increase some lifespan and maintain a longer period of prime. Perhaps before you grow old, I can develop a new generation of serum and continue to extend your lifespan."

"I know you are a little nervous now. What I want to tell you is that I have used this serum for myself. Look, I have not grown anything that shouldn't have grown in my body now, and I haven't slept all day and night, and I don't feel tired at all."

Vivier actually used her own experiments to prove how confident she has in the genetic agent developed this time.

"Vivier, I, I'll do it first." A female agent raised her hand.

The other male agents were watching each other. They still remember that once before, Vivier also said that the research and development was successful, but after a certain male agent was used, he could no longer hold the ball.

Compared to strengthening the body, they care more about that aspect. If they can strengthen that aspect, they will be willing to live a few years later.

"Agent f, don't you try it? I know your body has mutated, but maybe this can help you continue to strengthen." Vivier looked at Fan Mang, her eyes shining. This is the experimental subject she wanted most.

Fan Mang waved his hand quickly: "I don't think I need this thing, but j should try it."

j took two steps back: "f, don't talk nonsense, I'm in good health. Besides, as an ace agent, how can I compete with young people for such opportunities?"

What a joke, he would never try it until it was completely proven to be safe.

Fan Mang is not sure. After all, after Vivier developed it, she did too few experiments and lacked data support. Now this data does not conform to statistics at all, and there are too few samples.

Moreover, many mutations are discovered later, and many mutations have a certain incubation period.

Fan Mang wants this kind of potion not only for Batman, but also for Lin Yue, so there must be no problems.

"j, don't you believe in my research? Don't forget that I cured you several times when you were injured." Vivier was a little unhappy, "Since that's the case, then after success, you will be the last one to use it!"

A serum was drawn into the syringe and pointed at the female agent's arm, and the serum was quickly injected.

"Okay, wait next to you. If you feel hungry, eat, drink water when you feel thirsty, and tell all your feelings."

Not only Fan Mang and J were watching here, but several ace agents were very concerned about this research and development, after all, it was related to all of them.

Who doesn’t want their bodies to become stronger? Who doesn’t want to be young and last?

When dealing with alien creatures, sometimes you have weapons that can kill the opponent, but if you don’t react enough, you will be defeated or even die.

Every year, Mib recruits some new agents, not only because some agents retire, but also because many are under-numbered due to the sacrifice of agents.

Look at Agent F, bare hands and empty fists are also the best in the entire Mib combat power, and this is the goal everyone strives for.

“Ah~~~”

A person who was injected with serum suddenly let out a painful scream, and everyone was startled, but they found that the other party's scream seemed to be too long. Is the lung capacity so big?

I kept shouting for three minutes before I stopped. Everyone leaned over and saw that the other party was fine, so they felt a little sweaty.

"How are you? Something is wrong? Can you answer now?" Vivier asked hurriedly.

"It's nothing, I feel like my muscles are torn, it hurts and itchy. I'm still very hungry and thirsty. Can I give me a glass of juice?"

After all ten volunteers were injected, each person's physical changes were recorded in detail, and they could not leave. They had to observe for a period of time, and they were given blood tests and then had some physical tests.

But from the preliminary perspective, no one's body has undergone significant mutations at present, which is also good news.

Fan Mang has been at the headquarters these days and hasn't gone anywhere. A week has passed quickly. The results of blood tests and physical examinations have all come out. It is preliminary to judge that the serum has been successfully studied.

The physical fitness of all experimental personnel has been significantly enhanced, running faster, jumping higher, and even their reaction speed has increased significantly.

The ability to resist strikes and recovery speed has also been significantly improved. An agent with average endurance can now run a marathon.

As for delaying aging, this has also been confirmed in cell sampling observations. Everyone's metabolism has accelerated. The disadvantage is that they need to replenish energy at any time, that is, they need to eat more.

There are many other detailed tests, all of which prove that this super serum has been successfully developed.

"Everyone, I am very happy to announce to everyone that the super serum we have always wanted to develop has been truly successful. Among the yellow, white and black people on the earth, we have done experiments, including men and women, as well as some mixed-race races, none of them have adverse reactions."
