"This sex change refers to the change of gender, a medicine they researched, which can turn a strong man into a weak woman, and a woman into a man, and Shou Yuan refers to the change of age, which can make young people grow old in an instant, and can also make the old people younger, and even become children." Xiaofeng said.

"So powerful, did they succeed?" Feng Ge asked, isn't this sex transfer a modern sex reassignment surgery? It's just that modern times require all kinds of surgeries, and here one medicine can solve the problem?

Shou Yuan, it's even more exaggerated.

Instantly aged, rejuvenated? This looks like something from a legend no matter how you look at it.

But this bizarre fantasy world is full of all kinds of impossibilities, isn't it?

"I don't know if they have succeeded, but for this kind of thing, they have been experimenting for hundreds of years, persecuting many innocent people, and because they have the support of the high-level leaders of the Four Realms behind them, they have become more fearless and have committed frequent crimes in recent years." Xiaofeng said.

"The support of the top of the Four Realms?" Feng Ge's eyes narrowed slightly.

"That's right, I heard that the high-level of the Four Realms want to use this medicine on the battlefield, think about it, if the two sides are fighting, the warriors of one side instantly become an old man with no combat effectiveness, or a woman, what will be the result? They can even use drugs to turn weak women into strong men and send them to battle. Xiaofeng said.

"That woman is not necessarily weak, and a man is not necessarily strong!" Feng Ge said.

"This is the power of this drug, if a woman uses it, the strength will increase exponentially in a multiplier, on the contrary, if a man is drugged, the strength will be greatly weakened, and the stronger the man, the weaker he will become.

In the same way, the strength of young people will become children, or the strength of old people will weaken, but if it is the other way around, it will increase dramatically. Xiaofeng said.

Feng Ge's eyes narrowed, and when he thought about it carefully, he was really scary.

Those who are high in power, for the sake of profit, do not hesitate to use means to such a point?

"Then you Boundary Keepers are against them, aren't you afraid of offending the superior behind them?" Feng Ge asked.

Hearing this, Xiao Feng raised his head with pride, "If our Boundary Keeper clan is afraid of this, it will not be the Boundary Keeper clan, eliminate treachery and evil, and destroy no way, this is the ancestral training of our Boundary Keeper Clan, besides, with the ability of that group of people, it is impossible to find our Boundary Keeper Clan." "They can move in the city.

"Amazing, what I admire most is people like you who uphold justice." Feng Ge said with a look of adoration.

"Don't talk about this yet, I'm done, so do you have any good ideas?" Looking at Feng Ge, Xiao Feng asked.

"What are you going to do?" Looking at Xiao Feng, Feng Ge asked.

"What else can I do, the civet cat has already tracked down to the lair of the Heavenly Grant Palace, of course, it is a strong attack by artillery fire." Xiaofeng said.

Feng Ge shook his head, "No, since it is an experiment, there should be many innocent people in the Heavenly Grant Palace now, if you attack like this, you will not force that group of people to be in a hurry, and directly use that group of people as cannon fodder, and then they will escape, and in a worse situation, if you are poisoned by them, you will not be wiped out all at once." Feng Ge said.

"So what do you say?" Looking at Feng Ge, Xiao Feng asked.
