After Guo Yancheng observed for more than ten days, some of these animals were dead, while others were barely alive but seemed to die at any time.

So he lost patience and began to experiment on people.

The result once again disappointed him. Anyone who took the girl's blood would explode and die.

If it is diluted blood, people who take it will be as dying as those animals.

Just when Guo Yancheng was disappointed, a disciple unexpectedly persisted and his martial arts skyrocketed!

He was overjoyed and hurriedly investigated and found out that this disciple was actually the one with the strongest internal energy among all the people who experimented. After taking the girl's blood, he immediately meditated for three days to exercise his internal energy. As a result, he suffered three days of hard work.

The practice was comparable to his ten years of meditation, which made his inner strength soar.

Guo Yancheng was inexplicably excited, thinking he had found the right path, but reality gave him a blow again.

On the afternoon of the fourth day, when this disciple was meditating, his meridians and blood vessels all over his body burst and he died. He died very miserably.

Guo Yancheng was very unwilling. He learned from the pain, summed up his failure experience, and finally came to two conclusions:

First, this disciple's internal strength is still not high enough and his potential is too low, so he cannot withstand the girl's blood; second, the girl's blood needs to be diluted again.

After reaching these two conclusions, Guo Yancheng set the target of the experiment on his eldest disciple Feng Biao.

Feng Biao has the highest talent potential among all the disciples, and also has the strongest internal strength, almost catching up with his master.

But the problem is that Feng Biao participated in all the experiments, and he knew the power of the girl's blood.

This was not a problem for Guo Yancheng. He mixed the diluted blood into wine and tricked Feng Biao into drinking it. Only when Feng Biao felt something was wrong did he tell Feng Biao the truth.

Before Feng Biao could take action, he threatened Feng Biao's wife and children to force Feng Biao to cooperate with his experiment.

Feng Biao surrendered as expected, but he resented Guo Yancheng very much in his heart. Although his daily martial arts progress was rapid, he could clearly feel a violent force entrenched in his body, becoming more and more unstable and becoming more and more unstable.

The trend of explosion.

He had no confidence that he could control this increasingly violent energy, and he had no idea how to resolve it.
