Li Feng turned around and saw several sword marks on the wall over there. There were traces of sword intent left in these sword marks. Those sword intents were very clear, as if they had been left not long ago.

But based on these alone, it was impossible for Li Feng to judge whether Li Xinyu left it behind.

At that moment, Li Feng turned to look at Mr. Luo.

"Someone came here more than half a month ago, but the environment here is special and the atmosphere is very weak, so it is difficult to judge who has been here." Veteran Luo said after flipping through the tracking disk in his hand.

"More than half a month ago?"

Li Feng, Nangong Xin, and Xu Qing looked at each other.

Li Xinyu and Xiaobai disappeared a month ago. During this month, the Blood Eagle Guards were stationed in Starfall Valley, so no one else entered Starfall Valley during this month. If what He Xuanyan said is true,

If the Fallen Star Valley is the only way to enter the core of the Lich Mountains, then basically Li Xinyu and Xiaobai who passed here half a month ago are the same.

"Let's move on." Li Feng made a quick decision.

The palace was very large and deep, but there was no danger. Li Feng and the others passed through the palace easily.

After walking for half an hour, Li Feng and others arrived at the fork.

"Master Feng, this way." Mr. Luo looked at the tracking disk in his hand, then pointed to the left and said to Li Feng.

Li Feng nodded and walked to the left.

Xu Qing, Nangong Xin and others followed closely behind.

An hour later, under the guidance of Mr. Luo, Li Feng and others arrived at a cave.

"Li Feng, look..."

As soon as he arrived in the cave, Nangong Xin pointed in front and screamed in horror.

Li Feng followed Nangong Xin's finger and saw a huge black hole in front of him. From the black hole, monstrous demonic energy spewed out. Waves of terrifying demonic roars that made people numb their scalp came from the black hole.

When you come out, it's like there are thousands of demons roaring in the black hole.

Hearing the sound of the magic flute, Li Feng and others felt a fear coming from the depths of their souls.

"Young Master Feng, the person you are looking for is inside." Mr. Luo pointed at the black hole in front of him and said.

"What?" Li Feng's expression changed several times.

Li Xinyu and Xiaobai are not demon cultivators, how could they enter this black hole? Entering this black hole filled with demonic energy, do Li Xinyu and the others still have a chance to survive?

"Li Feng, there is an aura in this black hole that even scares me. If your sisters and others enter it, they will be in trouble, so you'd better not go in." He Xuanyan said.

Li Feng shook his head. It would be fine if he didn't know the whereabouts of Li Xinyu and the others, but knowing their whereabouts, he couldn't ignore them.

After thinking for a while, Li Feng said: "You guys wait here, I will go in and take a look alone."

"Li Feng, this is too dangerous." He Xuanyan said.

"The person inside may be my sister, so I have to go in no matter what." Li Feng's tone was unquestionable.

"Li Feng, then be careful." Nangong Xin knew that Li Feng had made up his mind, so he didn't stop him.

Li Feng nodded, and then said to He Xuanyan: "He Xuanyan, you stay here and help me protect Nangong Xin and the others."

"No, Li Feng, I want to go in with you." He Xuanyan shook his head and said.

"What?" Li Feng was surprised, obviously he didn't expect He Xuanyan to say such a thing. But after thinking about it, Li Feng shook his head: "No, He Xuanyan, it's too dangerous here, you can't go in.

"

"Li Feng, let He Xuanyan go with you." Nangong Xin said at this time.

"Yes, Li Feng, you will help me deal with Wang Biao in the future, and I will help you find your sister now." He Xuanyan also said.

"This... okay." Li Feng thought for a while, nodded, and then said: "He Xuanyan, you wait here for a while, I will send Nangong Xin and the others out."

"Okay." He Xuanyan nodded.

Li Feng made a look at Nangong Xin and the others, and then returned the same way.

After walking for five minutes, Nangong Xin said: "Li Feng, it's almost done..."

"Then I will send you to the Xuanling Realm right now." Li Feng said solemnly. Without He Xuanyan by his side, Li Feng would not worry about Nangong Xin and the others wandering around alone in the core of the Lich Mountains. After all, even Xu Qing, who has the highest combat power, is only the King of Martial Arts.

Not to mention the sixth-level combat power compared to the fifth-level monsters, but also compared to other warriors, Xu Qing's strength is in the middle and lower reaches.

"Okay." Nangong Xin nodded, suddenly remembered something, and said to Li Feng: "Li Feng, He Xuanyan is not simple, you have to be careful."

Li Feng raised his eyebrows, what did Nangong Xin mean?

Could it be that He Xuanyan is also a very scheming person and his cynicism is just a superficial phenomenon?

However, Li Feng didn't ask any more questions at this time. In order to prevent He Xuanyan from discovering anything, he took Nangong Xin and the others into the Xuanling Realm and immediately returned the way they came.

"He Xuanyan, let's go in."

Arriving in front of the black hole, Li Feng said to He Xuanyan.

"Um."

He Xuanyan nodded and followed Li Feng into the black hole.

In the black hole, the demonic energy was vast. As soon as he entered it, Li Feng felt like he had entered the Heavenly Demon Cliff in the Milky Way Realm last time. Endless demonic energy swept in, even if Li Feng circulated the devouring power and the demonic true essence lake,

There are also some people who find it difficult to resist this terrifying evil spirit.

Li Feng glanced at He Xuanyan, but there was nothing unusual about He Xuanyan at this time.

After going deep into the black hole for several minutes, Li Feng felt that the demonic energy carried an evil aura.

This was an evil aura that was difficult to express, which frightened Li Feng.

"Boom! Boom! Boom..."

A quarter of an hour after Li Feng and the others entered the black hole, a drum beat came from the depths of the black hole. The drum beat was deafening and soul-shaking.

At this moment, Li Feng felt like his blood was boiling and his head was spinning.

"Li Feng, are you okay?" He Xuanyan's voice came.

"It's okay." Li Feng felt uncomfortable, but since he was here, he would insist on whatever he said.

"Touch!", "Touch!", "Touch!"...

At this time, a breath so powerful that it made everyone tremble surged from the front, and then, a burst of heavy footsteps reached the ears of Li Feng and the two of them.

Every time the footsteps sounded, the ground shook. Both Li Feng and Li Feng were shocked. Could there be any fear in this?

"Li Feng, be careful, this aura scares even me..." He Xuanyan hurriedly said to Li Feng after feeling the aura.

Li Feng nodded, the Aurora Shield and the Blood-Transforming Knife appeared in his hands, and he was on high alert.

Soon, a huge black shadow appeared in Li Feng's consciousness.

As the black shadow stepped out step by step, the entire ground shook.

Whoosh!

The next moment, this black shadow waved its palm towards Li Feng and the others.

"Rumble..."

A big hand, carrying terrifying energy, flew down towards Li Feng and the others. In the black hole, the endless demonic energy was dispersed.

Li Feng's expression changed slightly, and the Aurora Shield moved forward to block it.

boom……

There was a loud noise like the earth was shattering, and Li Feng was blown away by the terrifying energy.

"Whoosh!"

He Xuanyan's figure flashed and caught Li Feng: "Li Feng, are you okay?"

Li Feng shook his head and then looked forward.

"This is another corpse infected by demonic energy, but there are still residual soul fluctuations on this corpse." He Xuanyan said.

"Is there any residual soul fluctuation in the demon corpse?" Li Feng was shocked and a little unbelievable.

As a corpse cultivator, Li Feng understands very well how difficult it is to leave soul fluctuations on a corpse. Since ancient times, except for the Juesha Yin Corpse, only those who practice the corpse refining technique

Only corpse cultivators who have reached the highest level can use special techniques to collect the remaining souls between heaven and earth, and then attach them to the corpse.

And these demon corpses were obviously not made by corpse cultivation, but they could also have soul fluctuations. How could this not shock him?

"Yes. These soul fluctuations can easily determine the existence of a person. Wang Biao once said that when the evil demon was suppressed here, many people went deep into the place of suppression to rescue the evil demon. And these corpses

, are what those people left behind. The reason why they became like this is because the evil energy released by the evil demon infected them over the endless years." He Xuanyan said.

Li Feng remained silent.

Can infection with demonic energy turn a corpse into a demonic corpse?

If Li Feng was not a corpse cultivator, he would definitely believe this explanation, but as a practitioner of Tianyuan Corpse Refining Technique, he knew very well that for this reason alone, there would never be such a terrifying demon corpse.

"roar……"

Just as Li Feng and He Xuanyan were talking, the demon corpse in front roared, and the sound shook the sky, causing the entire space to shake.
