Hu Xin took the thirty-two heroines to board the drilling turbine together, bid farewell to Tan Xiongfeng, and drilled deep underground.

The cave is under the entire battlefield, but after going deeper, a super strong stone will appear, and the current technology of the genetic world cannot destroy that kind of stone at all.

Because Lu Yun's spaceship helped Chen Yuanyuan, the estrangement caused by Lu Yun almost killing Murong Fei'er was finally resolved.

The ground was dark, and the soil was getting darker and darker.

"Are these all blackened by endless blood?" Huang Xingyue couldn't help but ask.

Tan Ru said in his heart, "The battlefield has existed for more than 10 million years, and the attacks of the alien alliance have never stopped, so it is normal for the soil to be dyed black. ”

Agnes said, "Wouldn't so much genetic blood soaking the ground nourish evil creatures?" ”

Tan Ruxin smiled bitterly, "I used to have such thoughts, but the truth is that the soil under the battlefield is extremely dark, and no creatures have been found. ”

"However, this black soil is extremely aggressive, and creatures don't dare to touch it directly, except for the natural caves that can go underground in the past, we only explore other places through technology, so whether there are creatures or not, I don't know."

Hu Xin looked at the black soil outside, and he was also curious, "Lu Yun, stop, I'll go get some black soil and have a look." ”

With the system, Hu Xin firmly believes that he can see through the secrets.

Lu Yun obediently stopped the drilling turbine and opened a small gap.

The black soil is also hard and does not penetrate directly.

Hu Xin walked over, touched the black soil, and suddenly felt a bloodthirsty breath surging into his mind, and his eyes were blood-red, almost losing his mind.

Quickly put it away, looking at the black soil, shocked to the extreme.

Other people were also curious and wanted to touch the black soil, but when they saw Hu Xin's changes, they immediately gave up this idea.

"Why is the black soil of the system so weird?"

[Ding, the black soil is suppressed by the super god-level formation, and the resentful spirits of all creatures are sealed in it, and the anger is soaring, and the anger can be refined to increase the fighting intent for killing intent, and the refining consumes 100 million strengthening points per second, is it refining? ] 】

"Refining."

[Ding, the host needs to contact the black soil to refine, note, the more you contact, the stronger the refining effect.] 】

Hu Xin smiled bitterly, this is to let him enter the black soil.

However, as long as he could improve his cultivation, he couldn't care about so much.

After all, now that the family has a big business, more than 30 wives, if you don't have enough strength, how can you protect them?

"Lu Yun, open the warehouse door, I want to enter the black soil to cultivate."

"Huh?"

was stunned by Hu Xin's words, and looked at him with incredible eyes.

It's black soil.

Lu Yun frowned and said, "Husband, I feel a powerful aura from the breath of black soil, the black soil itself, you have also been exposed to it, if this is completely wrapped in black soil, I am worried about ......."

"Don't be afraid, I'm sure, after this cultivation, my combat power is bound to skyrocket, so there will be one more chance to avenge you."

When it came to revenge, Lu Yun was immediately moved, and controlled the drilling machine to open the warehouse door.

The black soil is extremely hard and diamond-like, so you don't have to worry about flooding into the driller.

"Husband, stay safe." Everyone said in unison, the worry in their eyes undisguised.

"Rest assured, my husband won't do things that I'm not sure of."

After finishing speaking, he turned into a humanoid weapon and rushed fiercely.

Boom.

With a loud bang, Hu Xin's whole person smashed into the black soil.

Suddenly, the majestic and irrepressible anger entered the body and poured into the mind.

These angry spirits seemed to be interesting, frantically attacking Hu Xin's brain, wanting to control and enslave him.

"Systematic refining of aura."

[Ding, the host refining is refining the qi, consuming 100 million enhancement points per second. 】

[Ding, the host refines the aura and obtains 100,000 killing qi points. 】

【Ding, host refining ......]

The murderous value has skyrocketed, and what Hu Xin has to do is to stick to his heart wholeheartedly, and not be attacked by the terrifying anger to break his mind and will.

An hour later, the murderous value had already exceeded 100 million.

[Ding, congratulations to the host, willpower has been strengthened, and combat power has increased by 500%.] 】

Hu Xin, who was struggling for a long time, was overjoyed when he heard this prompt.

I thought that obtaining murderous energy was the biggest gain, but I didn't expect that the painful resistance to the invasion of terrifying anger actually tempered the willpower, and the system was directly converted into a combat power increase, cool.

The third hour has passed, and the murderous value has already exceeded one billion.

[Ding, willpower is strengthened, and the combat power increase is increased by 500%.] 】

Another 500 percent was added, for a total of 1,000 percent.

Hu Xin was extremely happy, although there were more and more anger, more and more terrifying, as if the anger in the black soil under the entire battlefield was consciously surging towards him.

The pressure is getting bigger and bigger, but seeing the increase in combat power, Hu Xin insists more firmly.

Crisis and chance coexist.

Hu Xin understands that there is no free lunch in the world, and he can't resist death if he carries the past and becomes stronger.

For a better future, in order to protect the people around him, Hu Xin gritted his teeth and insisted.

When the tenth hour came, the killing value exceeded 10 billion, and the increase in combat power reached 1,500 percent.

[Ding, congratulations to the host, refining the power of the resentful spirits in the anger, the soul is strengthened by one hundred, and the combat power is converted by one thousand. 】

Hu Xin clearly felt the ethereal soul, which seemed to suddenly become heavier, and seemed to be able to feel what a soul was.

This feeling is very subtle, and the strengthening of 1,000 percent combat power is even more intense.

Now Hu Xin, even if he is in pain, he is also happy.

Airplanes.

In the black earth, there was a strange noise, as if something was roaring.

It's the kind of sound that they can't hear in Valia in the driller.

Only Hu Xin, whose soul has become stronger, heard it.

I was very surprised, as if some giant beast was provoked.

Hu Xin also guessed something, and felt that it should be a resentful spirit, and it was a very powerful resentful spirit.

[Ding, a transcendent gene-level resentful creature is approaching, refining can strengthen the soul by two hundred percent, refining needs to consume one hundred trillion evolution gene points, whether to refine or not. 】

"Refining."

Hu Xin was very excited.

Although one hundred trillion evolution gene points have been consumed, two hundred percent of the soul has become stronger, and the combat power of the transformation is two thousand, which is terrifying when you think about it.

More importantly, Hu Xin realized that the strengthening of soul power seemed to be the most difficult.

If he hadn't entered the black soil this time, he wouldn't have had such a chance.

[Ding, it is refining the transcendent gene-level resentful spirit creatures, which is expected to take three minutes and consume 100 trillion evolution gene points. 】

Three minutes passed quickly.

[Ding, congratulations to the host, refining the transcendent gene-level resentful spirit creatures, gaining 200% soul strength and converting 2,000% combat power. 】

After the two hundred percent soul strength was strengthened, Hu Xin felt that the soul was becoming more and more substantial, but it was only a feeling, in fact, the soul was still void and could not be perceived.
