In that portal, there used to be majestic demonic energy pouring out, but now, there is endless death energy emerging from it. At the same time, with the emergence of these death energy, the amount of demonic energy pouring out from the portal has decreased.

Quite a few.

However, Li Feng was stunned by this change.

Yaozhu just said that the demonic energy emerging from the mausoleum may be related to the monsters under the sky cliff, but what is the death energy? The monster is not a dead thing, and it is impossible for it to produce such a strong death energy.

.

Could it be that in addition to monsters, there are also dead things in this tomb?

With doubts in his heart, Li Feng looked at Yaozhu.

"Master, I don't know about this anymore." Yongzhu shook his head. He didn't know what was going on in this situation.

Li Feng was a little disappointed, but he also knew that Yaozhu was not omnipotent, so he didn't say much, and immediately looked at Tianxuan: "Tianxuan."

"Whoosh!"

Tianxuan's figure flashed, came to the door, opened his mouth and took a breath.

Rumble…

The death energy that emerged from the portal was like a torrent and was inhaled by Tianxuan. As the endless death energy was inhaled, the aura on Tianxuan's body also slowly strengthened at this moment.

Seeing this, Li Feng breathed a sigh of relief.

Now that Qingyou New Banner is gone, he can only rely on Tianxuan to solve these dead energy. If Yongzhu cannot solve it, he can only find a way to leave the ancestral land of Tianmo Palace.

But for him, these death auras are an opportunity to practice the Tianyuan Corpse Refining Technique?

Although he practices Tianyuan Corpse Refining Technique and cannot absorb as much death energy as Tianxuan, as long as there is a little death energy, it will have a very big effect on his Tianyuan Corpse Refining Technique.

At that moment, Li Feng sat down cross-legged and began to practice.

Tianyuan Corpse Refining Technique, Li Feng has now reached the fourth level. Based on the situation at the fourth level, it is no problem to control Tianxuan, but this does not mean that Tianyuan Corpse Refining Technique does not need to be practiced. With Tianxuan

As his strength improves, he must also improve Tianyuan Corpse Refining Technique.

What's more, Li Feng learned from the introduction of Tianyuan Corpse Refining Technique that Tianyuan Corpse Refining Technique was not as simple as he thought. If Tianyuan Corpse Refining Technique could be improved, it might be of unexpected help to him.

.

More importantly, practicing Tianyuan Corpse Refining Technique can improve his Yin attribute true energy.

Among the nine basic attributes, yin, yang, time, and space are the most difficult to cultivate and are also very rare. The two attributes of time and space are okay. You can use the five elements of true energy to rotate and reverse to practice, but the yin attribute

Different from the Yin attribute. So far, Li Feng has not found a good way to improve them.

All along, Li Feng only converted into these two attributes through the Main True Essence Lake when he was practicing. However, this method was too slow.

However, it was because he practiced Tianyuan Corpse Refining Technique that he had the Yin attribute. Therefore, practicing Tianyuan Corpse Refining Technique also increased his Yin attribute true energy. So now, when Li Feng practices Tianyuan Corpse Refining Technique, he also has

The idea of ​​increasing the Yin attribute essence.

With the operation of Tianyuan Corpse Refining Technique, traces of death energy were absorbed by him and entered his body.

Half an hour later, with the practice of Tianyuan Corpse Refining Technique, an extremely cold flame appeared in his body. This was the yin fire that gave him the yin attribute in the first place. As soon as these yin fires appeared, they entered his body.

Dantian, converted into his Yin attribute true energy.

An hour later, Li Feng opened his eyes.

After an hour of practicing absorbing dead energy, Li Feng had reached the limit and stopped practicing. However, although there was no breakthrough in the Tianyuan Corpse Refining Technique, Li Feng felt that he was not far from a breakthrough. What he lacked now was an opportunity.

And his Yin attribute True Essence Lake was replenished by Yin Fire, and became full, which made Li Feng ecstatic. There were multiple True Essence Lakes in his Dantian, and he could only absorb these True Essence Lakes one by one.

Only when it is filled can one break through. This is one of the reasons why his cultivation level is dozens of times that of others. Now that the Yin attribute true energy is filled, relatively speaking, the most important true essence lake has been solved.

Li Feng looked up at Tianxuan and saw that Tianxuan was still at the door absorbing death energy and practicing, so Li Feng walked towards Hu Yuanyuan and the others.

"Li Feng, are you okay?"

As soon as Li Feng entered the formation, Hu Yuanyuan, Li Xinyu and others came up to him. The corpse puppets had been solved just now, and Li Feng was practicing in front of the mausoleum. They thought something had happened to Li Feng.

"Fortunately, I got some unexpected gains this time." Li Feng replied.

"That's good, Tianxuan?" Hu Yuanyuan glanced at Tianxuan in the distance.

"Tianxuan is fine. We will go in after he solves these dead energy problems." Li Feng replied.

"Okay." Hu Yuanyuan nodded and let go of her worries.

"boom!"

At this moment, a powerful aura wave came.

Li Feng turned around and saw a powerful wave of aura erupting from Xi Qiupeng's body. He was delighted: "Xi Qiupeng actually broke through?"

To demon cultivators, demonic energy is like spiritual energy. As long as it can be absorbed and refined, it can improve one's cultivation. Among the many demonic cultivators under Li Feng, only Xi Qiupeng's cultivation is the highest.

Being controlled by the divine control technique, Li Feng naturally hopes that Xi Qiupeng can improve his cultivation. After all, he doesn't want his divine control quota to control a useless person.

When I was in the Houtian realm, in order to develop myself, without knowing that there was a quota for divine control in the divine control technique, I controlled a large number of Houtian realm warriors. But now most of these people are useless, and even because of their death,

It will affect his consciousness.

In the Yuanwu Mountains, he had no choice but to control Ye Su, Zhao Shi, and Xi Qiupeng, but he did not need the three of Ye Su to be like the Blood Killing Double Eagle one day. Therefore, at this time, Xi Qiupeng improved his cultivation.

Li Feng was very happy, even improving his cultivation level to a higher level.

"Young Master Feng." After Xi Qiupeng consolidated his cultivation, he came to Li Feng's side excitedly.

If it weren't for Li Feng, even if there was no internal strife in the Heavenly Demon Castle, he might have died in the hands of the Blood Demon Sect. Unlike now, he would still be able to break through in cultivation.

"Well, keep working hard." Li Feng nodded.

An hour later, the death energy pouring out of the mausoleum was almost absorbed by Tianxuan, and the demonic energy in the air became thinner. Li Feng said to Hu Yuanyuan and others: "Let's get ready to go in."

"good."

Immediately, everyone left the formation and came to the tomb.

"This is……"

The entrance to the mausoleum is a stone door. Standing at the door and looking at it, you can see a faint green light inside, like a will-o'-the-wisp.

"Tianxuan."

Li Feng directed Tianxuan to go in first.

A minute after Tianxuan entered, Li Feng led Hu Yuanyuan and others in.

"Everyone, be careful, Li Qingyuan, Zhang Peilei, you are behind, You Quanming is on the left, Xi Qiupeng is on the right, to protect everyone's safety." Li Feng said solemnly.

"yes."

Behind the tomb door is a long passage, walking in it gave Li Feng and others an eerie feeling.

"Brother, Xiao Jin said, there is a scary guy ahead."

At this time, Li Xinyu suddenly said.

"A scary guy?" Li Feng was stunned and became even more wary.

Whoosh!

At this moment, there was a sound of breaking through the air from ahead.

Li Feng looked up and saw a black shadow attacking Tianxuan from a distance, and they were instantly fighting with Tianxuan.

"Master, he is a puppet." Yaozhu said.

"Puppet? Yao Zhu, go and help Tianxuan solve it." Li Feng said solemnly.

"Okay." Yaozhu responded and flew over Li Feng's head.

Boom boom boom...

In an instant, Yongzhu, Tianxuan and the puppet were fighting together, and fierce attacks burst out from his body. The powerful moves could be said to be earth-shattering, shaking the entire mausoleum.

Li Feng took one look, then used his spiritual consciousness to extend towards the tomb.

There are demonic auras, corpse puppets, dead auras, and now puppets appear again. It is obvious that the defense of this mausoleum is more serious than he imagined. What Li Feng is most worried about is the restrictions in the mausoleum.

"It actually has the effect of blocking spiritual consciousness?"

After his spiritual consciousness extended several hundred meters inward, Li Feng felt that his spiritual consciousness was being blocked, and a flash of surprise suddenly flashed in his eyes. He obviously did not expect that something to block his spiritual consciousness was set up in the mausoleum.

In desperation, Li Feng had no choice but to withdraw his consciousness.

Li Feng frowned after taking a look at the fighting situation between Yongzhao and the others.

He never expected that the combination of Yongzhu and Tianxuan could not destroy this puppet until now. Is this puppet so strong and difficult to deal with? Judging from the combat power of this puppet, it should not be very strong.

yes.

"Master Feng, do you want me to take action?" You Quanming asked.

"Wait a moment." Li Feng shook his head. Although Yongzhu and Tianxuan could not defeat the puppets, they were not defeated, and he was not in a hurry.

boom!

In the sky, a huge roar came, and the puppets that were fighting against Yongzhu and the others exploded.
