........................

Nie Yun held the Wind Shadow Sword and Hei Yan together, hunting among the foxes wantonly. At this moment, in front of them, the huge Shuangyue Lake had been dyed in blood.

Before long, more than 2,000 foxes died at the hands of Nie and Yun.

"The spiritual power reserve in Dantian is less than 20%, so we have to withdraw from the battle."

Nie Yun thought to himself, and then swung his sword fiercely, splitting the last black water fox in front of him in half.

With a wave of his hand, he took the black flame into the space inside his body, and immediately used two escape techniques, water escape and earth escape, to quickly evacuate downwards and return to the underground blood palace. Only a bunch of foxes were left roaring up to the sky, roaring angrily.

Blood Palace.

Nie Yun took out several rejuvenation pills and drank them. He sat cross-legged on the ground and started to use the nine-turn mental technique to continuously restore his spiritual power.

As for Hei Yan, he doesn't have so many worries. He is currently lying quietly on the ground beside him, concentrating on digesting the black water fox and crystal core that he swallowed into his body.

Without the Fox King, it would be difficult for these fox groups to harm Black Flame. Because of this, when Nie Yun returned to the Blood Palace, he threw hundreds of crystal nuclei into his mouth at once, then closed his eyes and ignored him.

The corpses of these black water foxes, especially the corpses of the three-headed fox kings killed by Nie Yun earlier, were a rare and great source of nourishment for him. As long as Black Flame can digest all these things, his strength will definitely be able to go further!

But speaking of it, the cultivation of monster beasts is also simple. Monsters are creatures raised by the earth. They are born with strong physical bodies. They are favored by heaven and earth and become closer to spiritual energy. You only need to continuously swallow various essences to become stronger, and your physical body and innate secret skills do not require special training to be far superior to human monks of the same realm.

However, this kind of cultivation also has limitations. Firstly, the cultivation time is extremely long, which can often take hundreds or even thousands of years. Secondly, he is not like a human monk. He has many methods such as elixirs and formations.

If one of the strong men in the same realm is a human monk and the other is a monster. So it's not surprising that the monster beast is several times older than the human monk.

After a short rest.

Nie Yun began to focus on two things. On the one hand, he activated the Nine Turns Heart Technique to restore his spiritual power. On the other hand, his spiritual consciousness passed through the Blood Palace Formation and began to explore the situation of Shuangyue Lake again.

"There are still about three thousand Black Water Yin Foxes left, but because of the massacre just now, these remaining Black Water Yin Foxes are not very powerful and are distributed in extremely peripheral corners."

"If I want to kill them all, I'm afraid it will take a lot of effort. Should I kill them or not..."

Nie Yun's eyes narrowed slightly, thinking about the pros and cons.

After a long time, Nie Yun took back his consciousness.

He raised his eyes and looked at Hei Yan aside. At this moment, Hei Yan had already digested all the body and crystal core of the Black Water Yin Fox in his body. His aura became stronger and stronger, as if the realm he had broken through not long ago had been strengthened again.

Seeing this, Nie Yun suddenly smiled and said half-jokingly:

"Eating crystal nuclei as food. Have you ever experienced this kind of life when you were living in the Monster Mountain Range?"

Hei Yan tilted his huge python head and looked at Nie Yun, as if it was difficult for him to understand Nie Yun's words.

After a while, Hei Yan recalled a sentence in Nie Yun's mind through the system: "It's great!"

Nie Yun:…………

The ensuing massacre seemed to be extremely smooth, because the fox group was low in strength and encountered almost no obstacles.

Nie Yun never misses any opportunity to improve his strength. No matter whether he has experience or not, he will kill him whenever he encounters him!

What do you mean by killing innocent people indiscriminately?

Haha, what kind of Virgin White Lotus is this?

The jungle is the law of the jungle!

If Nie Yun doesn't kill others, then there is only one word waiting for him, death!

It didn't take long for Nie Yun to kill almost all the remaining foxes except for a few that escaped. After looking around and making sure that all the foxes around him were killed, Nie Yun activated his water escape technique and escaped towards the bottom of the lake.

"The reason why the Black Water Yin Foxes live here is because the energy of the crystal core dissipates after the death of the Blue Water Yin Python, making this place rich in Yin energy suitable for survival."

Nie Yun thought in his mind: "But the energy contained in the crystal core of a Martial Emperor-level monster is not generally huge. Even if it is sucked by the Black Water Yin Fox Group for many years and breeds a Yin Dragon Lotus, there will definitely still be some left! "

Thinking like this, Nie Yun turned his eyes to the bottom of Shuangyue Lake again.

In the bottom of the lake, there are many black stones scattered all over, which are Yin crystal stones!

Nie Yun dug out a fist-sized yin crystal stone with his hands, put it in his hand and looked at it carefully, feeling the strong yin evil spirit in it, and thought to himself: "These yin crystal stones are the real food source for the black water yin fox group. , these things are worth a lot of spiritual stones."

After thinking about it, Nie Yun activated his Water Escape Technique and wandered around at the bottom of the lake, collecting all the Yin Crystals he could collect into his body. He also carefully checked several times to make sure they were all collected. Omission!

As the saying goes, why don’t you get something for free?

"In the beginning, these yin crystals should have been scattered all over the bottom of the lake. However, due to years of consumption and lack of replenishment, the number now is not much."

Nie Yun looked at the bottom of the lake that had been cleaned by him and chuckled:

"However, even if I don't take it away, it will be completely consumed in a few hundred years. If the heaven and earth spiritual treasures are destined to be obtained by those who are destined to get them, it is better to take advantage of me!"

Due to Nie Yun's improvement in strength, the diameter of the space in his body has now expanded from ten meters to fifty meters now. There is no problem in containing all the Yin Crystal Stones!

Although Nie Yun's move was beneficial to him, it directly eliminated the possibility of the Black Water Yin Fox to thrive here.

But does Nie Yun feel guilty?

not at all.

Those so-called righteous people all shout that all the treasures of heaven, materials and earth are unavailable, but how many of them can actually do it?

If your interests come first, you should do everything you can to rob them by force!

If you really believe those righteous lies and don’t think about it, you deserve to be reduced to a weakling and be trampled on!

This is the world of cultivating immortals. If you are not ruthless, you will not be able to stand firm!

The competition here is who has the lower limit. Your character is noble. Sorry, you will die the worst!

Can Nie Yun fulfill the requirement of "taking all the treasures from heaven, materials and earth"?

Sorry, Nie Yun can't either, he is not a saint.

In Nie Yun's eyes, good is good and evil is evil. He never hides his evil.

So he chose to take them all away and let all these resources be used as nourishment for his own cultivation. This was the best destination!

After collecting all the yin crystals into the body space, Nie Yun returned to the Blood Palace again. He sat on the black throne and penetrated it with his spiritual consciousness.

"If what I expected is correct..."

Nie Yun kept moving his hands as he spoke.

Then, under Nie Yun's gaze, this bloody palace, which was hundreds of meters high and more than a thousand meters wide, actually began to slowly shrink until it shrank to the size of a palm and was held in the palm of Nie Yun's hand.

His spiritual consciousness penetrated into it, and the corpse of a hundreds of meters long green water Yin python was among them.

"Sure enough."

Nie Yun breathed a sigh of relief.

Originally, he was still worried about how to take away the body of the Green Water Yin Python, because the space in his body was not enough to hold this huge corpse.

Now it's better, just put it directly into the blood palace, and then put the blood palace into the body space, eliminating this trouble.

As his level of strength increases, Nie Yun will have greater and greater control over the Blood Palace.

However, this Blood Palace is already in ruins, and there is still a long way to go before it can be completely controlled and used by Nie Yun.

The underground space at this moment seemed empty because the originally huge Blood Palace was taken into the body space by Nie Yun.

"escape!"

Nie Yun did not stay where he was, but held the Earth Escape Technique and escaped directly in one direction.

In the inheritance of the ghost saint, there are not many exercises or secret techniques that Nie Yun can practice at present. Only a few secret techniques can be practiced directly, such as swallowing souls or searching for souls, as well as the preparation of some side poisons.

However, most of the techniques or secret techniques require the assistance of specific soul resources to practice. What Nie Yun lacks now is these soul resources!

Nie Yun did not have soul resources in his hands, but he could take a curved path to save the country.

If he has a large number of spirit stones in his hands, then he can purchase soul resources in large quantities from the trading houses. By then, Nie Yun's realm strength will begin to soar at an incredible speed!

Not long after Nie Yun left.

Suddenly, a terrifying scream shook the area for dozens of miles.

【Ding! 】

[Because the host acted too cruelly and slaughtered the fox group, the Fox Emperor became angry, and he will pursue the host endlessly. 】

【Please get ready. 】
