"This is, the recipe for the Super Soldier Enhancement Serum?" Nick Fury looked at what Ye Kai gave him, couldn't help but pick the corners of his eyes, and looked at Ye Kai with some surprise.

In Nick Fury's opinion, the Super Soldier Booster Serum started to be a very good, very good thing. It is very precious, and the famous Captain America is a super soldier enhancement serum that has long been made, which can turn a person from an ordinary person into a super soldier.

Not only S.H.I.E.L.D., but also the military and so on, have been peeping at such things as super soldier enhancement serum for a long time. S.H.I.E.L.D. won't talk about it for now, let's just say that on the military side, especially General Ross, isn't the reason why the Hulk was born because he originally wanted Banner to help him research the Super Soldier Enhancement Serum, and then there was only an accident with the Hulk?

So the Super Soldier Booster Serum is really a good thing, a very important good thing.

"What kind of side effects does it have?" Nick Fury looked at the information of the Super Soldier Enhancement Serum in his hand and asked Ye Kai.

As the director of S.H.I.E.L.D., Nick Fury naturally knows that there are side effects of super soldier enhancement serum, in fact, since the birth of Captain America, there have been many people and many forces studying super soldier enhancement serum, but so far, no one has been able to research a perfect super soldier enhancement serum, even if it is weakened in the weakened version, it will still make people's personalities become extremely irritable and easy to go to extremes.

It's like when General Rose was chasing the Hulk, one of his subordinates, that is, the one who had transformed into an abomination, before he became an abomination, he had been injected with a weakened version of the Super Soldier Enhancement Serum, and the effect, he did become stronger, but it was only stronger, the intensity was not great, but his personality became extremely irritable and aggressive. It is precisely because of this that after the failure of the pursuit of the Hulk, that guy didn't care about his own safety at all, directly injected the Hulk's blood, and then transformed into an abomination.

The weakened version, and even the effect is actually only one-tenth of the original enhanced serum, which has this side effect. So Nick Fury didn't believe that Ye Kai's Super Soldier Enhancement Serum would have no side effects.

Of course, Nick Fury also knew that Ye Kai and Mindy should have been injected with the Super Soldier Enhancement Serum researched by Ye Kai himself, at present, Ye Kai and Mingdi do not seem to have other serious tendencies and consequences, so the Super Soldier Enhancement Serum researched by Ye Kai should be safe, at least the side effects will be relatively small. Therefore, Nick Fury also attaches more importance to it.

"Side effects, well, indeed. There will be some side effects, after using it, the user's personality will inevitably become a little irritable, and a person who is usually quieter may also become a child with ADHD after using it. At the same time, he will cause some damage to the human body, and at the same time, after using this, the user will also reach a limit, no matter what he does, he will not break through this limit, and he will not become stronger, well, but no one will care about this. Because without it, the average person can't get stronger. Ye Kai said with a smile.

"Is it just these side effects?" Nick Fury was a little surprised, the few side effects Ye Kai said really had no effect at all, and even he felt that it was almost no side effects. Of course, it's not a good idea for people to become irritable, especially with their S.H.I.E.L.D. agents, who need a cool head a lot of the time. But it's not a big problem.

"Well, so, it's actually quite perfect, but there's a certain success rate in using it. According to estimates, the success rate of users is not too large, and only three or four out of ten people can succeed. Ye Kai shook his head, in fact, what he said was also true, according to this information, the effect of super soldier enhancement serum can only be like this. This is the result of Ye Kai's new research on this super soldier enhancement serum after using the Perfect Evolution Elixir, his body has evolved, and his brain has become more developed and intelligent, which is already the best that Ye Kai has been able to do so far.

"Less than 50 percent success?" Nick Fury frowned.

"That's right. So I've been hesitant about it, but you S.H.I.E.L.D. probably don't care too much about the low success rate. So it should be okay? Ye Kai looked at Nick Fury with a bit of mockery.

"No, Ye Kai, it should be said that it is our S.H.I.E.L.D. now. In fact, S.H.I.E.L.D. will not appear in the kind of situation you mentioned, because the people who can join S.H.I.E.L.D. are the elites of the elite, and it is very difficult to cultivate, so it is even more precious. Nick Fury looked at Ye Kai with a serious face and said very seriously.

"Hmm." Ye Kai looked at Nick Fury's appearance, and he didn't know if what he said was true, but it was actually reasonable for Nick Fury to say this, after all, the agents of S.H.I.E.L.D. can be regarded as the elite of the elite, and it is indeed not easy to cultivate.

"Well, actually, there's a modified version of the Enhanced Serum. It's just that, well, although the success rate has increased, there is a little, a little bit special, well, side effects. Actually, I don't know if it's a side effect. After all, some people's hobbies are more special, perhaps, they are also the type they like. Ye Kai said, his expression a little stranger.

"Oh? And a modified enhanced serum? What are the side effects you are talking about? "Nick Fury was particularly pleasantly surprised.

"Actually, my Super Soldier Enhancement Serum, at the beginning, I started to modify it with the genes of electric eels, and then I made some genes of other animals, and finally formed this version of the relatively safe Enhanced Serum, after the user uses it, well, there will be some changes in appearance." Ye Kai said with a strange expression.

"Change?" Nick Fury frowned, he was a little worried.

"That is, there will be some animal characteristics, such as a man with a pair of dog ears, a pig's nose, and maybe even a pair of wings?" Ye Kai's expression was strange.

It can be regarded as a disguise for Mindy's physical condition, Ye Kai studied the use of animal genes to synthesize enhanced serum, but its production method is relatively special, after all, there is a racial barrier between humans and animals, and the reason why Mindy will succeed is also because of the particularity of Thor Dog itself, as well as the effect of the blood of the little evil god in it.

Later, Ye Kai used all kinds of means to really study a formula, which can reluctantly reconcile the genes of animals and human genes, but although it is successful, however, the user will have some external performance. Of course, this situation is more in line with the situation of honking.

"What?" Nick Fury looked at Ye Kai in astonishment.

"Director Fury, I can help you if you want. For example, give your head an extra pair of cat ears or a cat tail. ”
