Du Xinrong ignored Lei Mingfei's dissuasion, and insisted on coughing up blood while finishing his words.

In fact, Du Xinrong's original intention of researching the Dark Blood Pill was indeed for Lei Mingfei, in order to help Lei Mingfei stimulate the potential in his body.

And all the drugs that stimulate potential on the market have more or less side effects, which will lead to an unstable foundation and affect the cultivation of the late stage, which is definitely not what Du Xinrong wants to see.

Although, during this research, Du Xinrong also germinated the idea of making himself stronger, but this idea is normal, and anyone wants to become stronger, whether it is to protect themselves or protect what they want to protect.

As for the sale of the Dark Blood Pill, this was actually Wu Weiteng's idea.

Soon after Du Xinrong recruited Wu Weiteng, after several tests, Du Xinrong concluded that Wu Weiteng, this kid, except for being too unruly and a little conceited, there is nothing wrong with it, at least, there is no problem in terms of integrity.

So Du Xinrong took him as an assistant and took him to his secret underground base to help Du Xinrong, and in the process of research, Du Xinrong's funds gradually ran out, and after a simple discussion, the two decided to take out the half-finished blood pill and sell it.

At that time, the Stygian Blood Pill had not been tested on humans, and only used some beasts in the forest as test subjects, and the beasts performed well.

And they also forgot that beasts and human bodies, whether in physical fitness or anything else, have big and small differences, and they cannot be compared.

It was only after they sold the first batch that they found out that this batch of semi-finished products had the side effects of consuming human essence and blood, and then they remembered that the physical fitness of the beast and the essence and blood in the body were stronger than that of humans, so they withstood the consumption of essence and blood by the Dark Blood Pill, and the human being, who was not very rich in essence and blood, suddenly couldn't bear it after such a consumption, and his body was almost even directly exhausted of essence and blood and died.

Fortunately, for the sake of secrecy, they started out anonymously, and no one knew that they were selling it.

But soon there was bad news, someone was copying his Dark Blood Pill, both in appearance and efficacy, it was almost the same, Du Xinrong felt bad in his heart, so he wanted to speed up the research progress, in order to research a complete Dark Blood Pill, to save everyone, and at the same time let Wu Weiteng destroy all the semi-finished products.

And the profits brought by the first batch of semi-finished products made Wu Weiteng taste the sweetness, how could he be willing to destroy these sweetness?

Wu Weiteng did not destroy it as Du Xinrong said, but hid it, borrowed it anonymously on the Internet and quietly continued to sell it, and Hong Yuan fished a lot of it.

However, Du Xinrong was not stupid, and soon found out that Wu Weiteng was wrong, and later found out that Wu Weiteng actually resold the half-finished blood pills that had been officially designated as banned drugs, and couldn't help but be furious and reprimanded him fiercely.

And it was from that time that the relationship between the two of them began to gradually crack, that is, people saw Wu Weiteng making trouble all the time, but Du Xinrong had to clean up the mess left by Wu Weiteng behind him as if he had no temper.

It's not that Du Xinrong has no temper, he's just afraid that he will lose his temper, Wu Weiteng will announce all the truth about this matter, and then his professor's top hat will fall off.

So Du Xinrong had to endure it like this, and when he was in the Phantom Forest, Du Xinrong became more and more unbearable, and finally broke out, but it also made Wu Wei kill because of the profit brought by the Dark Blood Pill.

This is also the reason why in the last time in the Devil's Forest, Wu Weiteng suddenly went berserk and wanted to attack and kill Du Xinrong.

Before that, Du Xinrong found that it would cause so many side effects to the human body, and he also understood that he could not use wild beasts as experimental subjects, but he could not use living people for experiments.

In this era, people's bodies have undergone subtle changes, and the mice that were used as experimental subjects by human scientists 500 years ago because of their close anatomy to the human body are no longer usable.

Therefore, Du Xinrong tried the law, of course, since there was a conflict with Wu Weiteng, Wu Weiteng was naturally indispensable to test the law.

The two often test the medicine in person, and the tester will lock themselves in a cage that is impregnable for them, preventing them from escaping out of control and harming others.

And the reason why he made that villain look before was because he didn't want Lei Mingfei to know, and he wanted to wait for his research to succeed and surprise him when the time came.

However, Du Xinrong couldn't give him this surprise anymore, although the corrosive energy of the missile was only passing by the super crazy Du Xinrong, but that energy quickly burrowed into his body like a maggot on the tarsal bone, wantonly destroying Du Xinrong's spleen.

And Du Xinrong finally couldn't hold back in the end, and told Lei Mingfei the truth, on the one hand, out of selfishness, he didn't want to be wronged by Lei Mingfei after his death, on the other hand, the Dark Blood Pill was only one step away from the full version, and what he had just taken was the latest version, which did not harm the body, but the body would have abnormal changes.

At the same time, Du Xinrong authorized his electronic chip system to Lei Mingfei, which contained the formula of the Dark Blood Pill and how to make the full version.

In fact, if Du Xinrong was given some more time, he would be able to research the complete version of the Dark Blood Pill, but, unfortunately, even with the rapid development of science and technology, there is still no if.

Lei Mingfei's eyes were full of tears, holding Du Xinrong's body that had been corroded inside, and after a few minutes, he gently put down Du Xinrong's already empty body and looked at Wu Weiteng angrily.

Wu Weiteng is not stupid, seeing that Du Xinrong and Lei Mingfei have said so much, and Lei Mingfei's expression is full of anger and sadness, Du Xinrong told Lei Mingfei something, and he also guessed a rough idea.

At this moment, Lei Mingfei was even more angry at himself, naturally knowing that Du Xinrong had told Lei Mingfei everything.

Wu Weiteng is also a ruthless character, he knows what he has done, and he also knows the consequences he will bear, so he took out the only bottle of dark blood pill left in the pocket of his clothes and drank it decisively.

After all, even if he pleads guilty now, it is a capital crime that can be avoided from living crimes, but Wu Weiteng does not want to suffer a living crime.

The previous version of the Dark Blood Pill has also been greatly improved in terms of the consumption of essence qi and blood, and it is controllable, and the enhanced state can be terminated at any time to stop the consumption of essence qi and blood.

The initial Dark Blood Pill will not stop until the essence and blood are burned clean, unless there is a strong person who is more than twice as strong as the user and forcibly terminates it with Nian Qi, and forcibly terminating it can only save one life, and his cultivation path can basically be said to be over.

Wu Weiteng, who took the improved version of the Stygian Blood Pill, didn't want to fight against Lei Mingfei, he took the Stygian Blood Pill to improve himself just to escape for his life.

However, he still made a desperate stance.

And when Wu Weiteng, who had obtained the Dark Blood Pill to improve his strength, put on a desperate fight, the momentum on his body was also burning, and he looked no less than Lei Mingfei.

Lei Mingfei saw that Wu Weiteng was about to fight to the death, and immediately became furious, "Son, Lao Du is so good to you, you actually betrayed him for the sake of profit, look how I teach you a lesson for him!"

Lei Mingfei's speech did not delay his action at all.

I saw that Lei Mingfei controlled the surrounding soil with a powerful mind qi and condensed it into a sharp arrow, but he didn't launch it, just hung quietly in the air, and at the same time, his body was shooting towards Wu Weiteng like an arrow.

Wu Weiteng, who has improved his strength, is actually comparable to Lei Mingfei's strength, and he is actually learning and selling now, imitating Lei Mingfei to control the soil with his thoughts and condense it into an earth shield.

However, because the mind qi was not solid enough, this earth shield was not very solid, and in the face of Lei Mingfei who was rushing, it was only resisted for a moment.

Lei Mingfei instantly broke through the earth shield, and his hand grabbed Wu Weiteng's neck in the shape of a claw.

Wu Weiteng also knew that he couldn't rely on that earth shield to resist Lei Mingfei, so he didn't hesitate to spend a lot of mental energy to condense one earth shield after another.

And after Lei Mingfei broke through all the earth shields, he found that Wu Weiteng, the kid, had slipped out of a hundred meters away, and was about to climb the pit wall to escape from this deep pit.

Seeing Wu Weiteng who was about to flee, although she knew that it was certain that Lei Mingfei would catch up with Wu Weiteng and successfully capture her, but at this time, Xiyuhua was in a bad mood, she didn't want to wait, so she wanted to take Wu Weiteng back directly.

However, at the moment when she was about to make a move, she suddenly felt that several not weak forces were approaching here at a high speed, so Xiao Yuhua withdrew her hand and quietly watched Lei Mingfei chase after Wu Weiteng.

When Lei Mingfei caught up with Wu Weiteng and was still some distance, several floating people suddenly appeared above the deep pit.

These people all stepped on the void, standing steadily in mid-air and looking at Wu Weiteng who was struggling to climb up.

Wu Weiteng's heart suddenly cooled most of the time when he saw them, and he knew that he was afraid that he would be planted here today, but he still refused to accept his fate, he wanted to fight!

Wu Weiteng completely activated the medicinal power of the Dark Blood Pill in his body, and immediately after, his body underwent drastic changes.

I saw that the skin on Wu Weiteng's body was centered on his chest, and the black color quickly spread to his whole body, and his eyes became blood-red, and then there was a "crackling" sound from his body, and his body swelled a little, but it was not much bigger, not much about the same height as Lei Mingfei, but a few points stronger than him.

The few people floating in the air were all old men who were over seventy years old, looking coldly at Wu Weiteng's changed body, and one of the old men opened his mouth and made a hoarse voice, "You ignorant child, do you know how much sin you have committed?"

"Hehe, you guys, you don't understand anything, come, fight with me, if you can defeat me, let you slaughter!" Wu Weiteng was extremely arrogant, his blackened face could still see the hideous color, and his blood-red eyes were full of crazy battle intent.

As soon as Wu Weiteng's voice fell, he took the lead in attacking!

What was surprising was that a pair of wide black-purple wings were born behind Wu Weiteng's soaring body, and the black-purple wings were vigorously fanned, sending Wu Weiteng's body into the air.

However, because he was not familiar with wings, this fan used too much force and sent himself nearly a thousand meters into the air.

The old man looked at Wu Weiteng's changes, still calm, and even sneered, "Useless work!" After saying that, his figure disappeared from everyone's field of vision in a flash.

And Lei Mingfei at the bottom was relieved, but he was also a little nervous......
