The brutal training made Vena mature quickly, and she saw all the hardships that Yun Feng had suffered in order to improve his strength, and she also knew what he was training for, so she didn't want Yun Feng to take such a risk.

It's a pity that although Yun Feng's choice disappointed Vina, there was nothing she could do to stop it. With her understanding of Yun Feng, as long as she is determined to do something, she will definitely not give up halfway.

Gritting her teeth, Vina's sad little face pulled together.

The military department will inevitably contact each candidate who meets the conditions to determine the final candidate. If Vena wanted to make trouble, at most she would report that Yun Feng had rejected the test, but when the military department inquired about it, it would inevitably be exposed, and it would have no effect.

After venting fiercely, Vina cleaned up her mood.

More intelligence must be gathered in order to deduce the feasibility of the trial.

Walking into the huge laboratory, Yun Feng met for the first time the genius scientist Dr Beka Bunk of the Navy Headquarters, who is said to have studied more than 500 years of technology in the world. Although uncertain, when it comes to Devil Fruit research, Beka Bunk is definitely second to none in the entire world.

I casually looked around, and it was full of inexplicable machines, and there were people participating in the experiment.

Seventeen, which is the final number of people willing to participate in this experiment. Among them, thirteen brigadier generals and four major generals, * the above basically would not consider taking such a big risk.

Those who can get to the rank of brigadier general and above are all determined guys, and they are extremely calm about the upcoming experiment.

Yun Feng was also very calm.

Yun Feng's calmness is not because he is determined, but because he can inexplicably shuttle through various worlds, and there must be reasons why he doesn't understand. In that case, why not give it a go.

"This experiment was simple. I've been researching Devil Fruits for a long time, and from what I've found so far, they're basically at the bottom of the sea. Combining each ability with only one at the same time, I'm guessing that the plant that grows the Devil Fruit is likely to be one. To put it simply, it is a plant that grows in the sea and is large enough to spread throughout the ocean. Of course, you don't need to go into such detail. ”

DR Beka Bunker's voice is shrill, his hair seems to have been untaken for a long time, and he is tall and thin, which is very much in line with the image of a scientist in Yun Feng's impression.

"I found the plant that grew the Devil Fruit by chance, and although it was only a small part, through various means, the plant was eventually able to survive. It's a pity I found a problem. ”

Becca Bunk was quick to explain, "Cultivated plants can't grow Devil Fruits, and there's no solution to this yet. However, through a lot of experiments, this plant grows in a very wide range of environments, and can even grow with the help of animal bodies, so I tried to grow on animals, and finally decided on this experimental project. ”

The corners of Yun Feng's mouth began to twitch uncontrollably, this thing didn't plan to plant grass on them. Imagining the appearance of a grass on his head or being wrapped around his whole body by vines, Yun Feng shuddered, it was simply too spoofed.

"Quack, rest assured. This plant can grow in the body of a person or an animal and will not show anything on the outside. Based on the best experimental results so far, it is likely that this plant, which grows dependent on humans or animals, will grow devil fruits in its body. Moreover, from the results of observation, the speed and type of Devil Fruit growth are related to the surrounding environment and personal thoughts, and it is not limited by the fact that there is only one fruit in the world. Other than that, there are no more results from this study for the time being.

I would like to warn you that this experiment is very dangerous, and so far, no one has completed this research, and it has been sucked into dry corpses by crazy plants. You can make the final decision whether you want to participate in this experiment or not. ”

After listening to Beka Bunker's words, Yun Feng was stunned.

Not because the study was bizarre, but because it had been a fantasy of his.

When he was sick and bored of studying the abilities of the Devil Fruit, Yun Feng had been guessing by himself how the Devil Fruit was grown.

Since it was a fruit, Yun Feng took it for granted that it was the fruit of a certain plant. Because it is rejected by the sea, it is likely that the growing environment and conditions are related to the sea. As for having only one plant and spreading the entire planet, that's pure YY.

Yun Feng became more and more sure that the world here was related to his inexplicable experience, and related to some dreams in his dreams, so he became more and more determined to participate in this experiment.

"Very good, no one has withdrawn, since everyone has decided to participate in this research experiment, according to the document issued by the military department, all the participants will be upgraded by one rank, of course, provided that you can survive."

Seeing that no one had withdrawn, Becca Bunk spoke as he motioned for his assistant to take out a petri dish at a constant temperature, and in the transparent liquid floated green shoots the size of a grain of rice.

"The experiment was very simple. I will plant a sprout like this in your heart, and it will absorb your flesh and grow in your body. Judging from previous test subjects, the stronger the person, the longer it lasts, so it can be inferred that the growth of Devil Fruit requires not only nutrition, but even energy. Of course, there is no clear answer because there are no successful cases yet. Okay, let's walk into the lab one by one. ”

It was indeed a simple operation, so simple that it only took about five minutes for each person, and Yun Feng didn't even feel any discomfort.

However, Yun Feng soon regretted it.

Half a month after the experiment, Yun Feng felt that this thing did exist in his body, and it was frantically absorbing his blood, muscles and even bones. That's not all, the feeling of pain and pain intertwined with sour hemp when the plant grows is almost to the limit of human tolerance. It's like a needle stuck in the flesh, and it's getting longer and longer, piercing into all parts of the body.

Yun Feng had no choice but to give up the training he had been insisting on, and in addition to eating and drinking every day, he meditated and cultivated his internal strength, which was the only way he found that he could reduce his pain.

For two years, Yun Feng lived every day in life rather than death. In the end, he couldn't even tell whether it was pain, soreness, or other sensations, and the whole person was skinny and insensitive.

As the only surviving test subjects, the other sixteen died within a year, and each of them died in exactly the same state, the flesh and marrow of their bodies were sucked dry, and only a skeleton was left when they died. Becca Bunk carefully examined Yun Feng thoroughly, and finally did not draw any conclusions. According to the success rate of the current experiment, I had no choice but to give up this research.

When Yun Feng finally didn't feel any pain, he couldn't help crying.

In the past two years, he has hardly had a good rest, and even if he occasionally naps, he still maintains a state of cultivation. But look at the current physical condition, he is as thin as a dry corpse, and his original deep internal strength is not left, and his strength is even less than that of Yicheng when he was the strongest.

"Hahahaha! I finally succeeded. ”

It wasn't Yunfeng who laughed, it was Beka Bunker.

Although this research has been decided to be terminated by both the Navy Headquarters and himself, the fact that there are successful cases proves that his research during this period has not been without results.

"This is what you call the Final Combat Power Plan? What do you think of a different name, the Worst Death Project? ”

Yun Feng, who was lying on the test bench, was in a very unhappy mood. Whoever is changed, who has endured two years of pain, but only in exchange for such a result, has to be mad.

"You're wrong. My experiment has indeed succeeded in you. Do you see this green line running through your body? ”

Becca Bunk pointed to the perspective projection of Yunfeng on the big screen.

Yun Feng almost stared out of his eyes, and he didn't see anything different. This thing is like watching X-rays or something, and anyone who is not a professional has to be blinded.

Didn't expect Yun Feng to understand it, Becca Bunk explained, "This line is the mature body of this plant in your body. These two years are the process of its growth from young shoots. Because it grows in your body, even in the blood vessels, muscles, intestines, etc., you will feel soreness, numbness, swelling and pain every time you grow. ”

Yun Feng gritted his teeth with hatred, but he could only stare dryly, after all, he was the one who agreed to participate in the experiment at the beginning, and he couldn't complain about others.

"And what's the use of these what you call silk?"

"Don't worry, listen to me explain to you." Becca Bunk was upset when he was interrupted by Yun Feng, and he was basking in the joy of successful research.

"There will not be two identical Devil Fruits in the world, but for each person, it belongs to a separate world of small cycles, that is, it can grow all kinds of Devil Fruits in your body. In my current judgment, because the human body is too insignificant compared to the whole world, it is likely to be affected by your surroundings during the growth stage of the Devil Fruit, simply put, if you are in an environment with glaciers everywhere, the first Devil Fruit to bear is likely to be the Frozen Fruit. You get the idea! ”

Yun Feng was confused for a while, and then summed it up, "In other words, all kinds of devil fruits will grow in my body in the future, right?" ”

"In a sense, yes!"

"Your sister! I've got a belly of devil fruits in my stomach and it's a fart, so they won't dissect me and take the fruit out and eat it, I might as well kill the! ”

Yun Feng shuddered when he thought that his body was full of countless Devil Fruits, and then one day, after being dissected, he took out all the Devil Fruits. Such a result is really not as fast and comfortable as suicide.

Becca Bunk rubbed his chin and thought for a while, "It's hard to deduce this because it didn't work out." However, my guess is that if you can successfully grow fruit, you should be able to use it directly. And there is another benefit, the existence of these silk threads can greatly strengthen your body, and you will be able to know about it when you cultivate in the future. As for what you're worried about, there's no need at all. It will take at least more than a year for a Devil Fruit to fully mature, and it is estimated that it will take at least ten times longer to be in your body, that is, if you live for a hundred years, you can only produce ten. ”

Yun Feng slammed down on the test bench, "Your sister! ”
