In the valley with no end in sight, Lu Feng and Su Yumo walked slowly on a gravel road, their eyes full of caution.

Although the Fire Demon Ape King has been killed, no one can say whether there are other demon beasts in this valley, and everything must be cautious in such a place full of unknown dangers.

As the two of them deepened, the surging light on the Fire Demon Ape King's inner pill in Lu Feng's hand became brighter and brighter.

Although Lu Feng didn't know what the reason was, he guessed that there must be something in the depths of this valley, which caused the reaction of the Fire Demon Ape King Neidan.

The eyes of the two kept scanning the surroundings, and gradually, their brows furrowed, as they found that as they went deeper and deeper, the environment in the valley became darker and darker.

At this moment, Lu Feng heard a creaking sound around him, and the sound seemed to be chattering his teeth, and then he felt that his clothes seemed to be ripped apart.

Lu Feng leaned slightly, and said jokingly: "I didn't expect that the daughter of the city lord, who is not afraid of the sky and the earth, would be afraid of the dark!" ”

"Who is afraid, I am not afraid!" In the dark, Su Yumo's stubborn voice came.

Lu Feng shook his head slightly, then took out a fire fold from the Qiankun ring, and blew it gently, and a faint ray of fire illuminated the surroundings of the two.

Lu Feng glanced at Su Yumo on the side, Su Yumo also looked at Lu Feng, the two looked at each other, Su Yumo's pretty face couldn't help but turn red, and the jade hand that grabbed Lu Feng's shirt was immediately released.

Lu Feng smiled slightly and continued to walk forward, and Su Yumo hurriedly followed.

With the help of the firelight, Lu Feng saw that the road ahead was gradually narrowing, there were rocks piled up along the way, there were still a few white bones on the ground, and there was silence around him, such a scene made people feel a little creepy.

Su Yumo couldn't help but shudder and said, "This place is too gloomy."

"It seems that there were once demon beasts here who also wanted to snatch the Xuanyuan Milk from the center of the earth."

Lu Feng's eyes looked at several huge bones on the ground, and sighed secretly, such bones are obviously not something that humans can have, which also further confirms the guess in his heart, there must be something in front.

Su Yumo frowned and said: "I once saw an introduction to the Xuanyuan Milk in the center of the earth in a book, if the demon beast can get this thing, it will be able to transform into a human form in the realm of the demon emperor, therefore, the vast majority of demon beasts are eager for this thing." ”

"It's no wonder!" When Lu Feng heard this, a hint of enlightenment welled up on his face.

According to common sense, a demon beast can only transform into a human form when it transforms into a realm, but if it has the Xuanyuan Milk in the center of the earth, when the demon beast steps into the realm of the Demon Emperor, it can achieve this goal.

Lu Feng knew that whether it was a martial cultivator or a demon beast, the higher the realm, the more difficult it would be to improve, and in the later stage of cultivation, even if he wanted to improve a small realm, he would have to spend a long time and great efforts, but the Geocentric Xuanyuan Milk could raise the ability of the demonic beast to transform by a big level, which showed how difficult it was for the demon beast to get out of the beast body, and it also showed how rare the Geocentric Xuanyuan Milk was.

The two continued to walk forward, and after a while, Lu Feng stopped, and Su Yumo also stopped.

"It's here!"

It seemed that he had reached the end of the valley, and with the help of the firelight, Lu Feng saw that there was a cave in front of him that was covered by weeds.

Lu Feng stepped forward slowly, brushed aside the weeds, and looked into the cave, it was still pitch black, but there was a faint smell wafting out of the cave, and that smell was very similar to the Xuanyuan Milk in the center of the earth.

At this moment, the Inner Dan of the Fire Demon Ape in Lu Feng's hand was also radiant.

"It's weird!"

A hint of excitement welled up on Lu Feng's face, and then without the slightest hesitation, he stepped into the cave, although Su Yumo was extremely reluctant, but he immediately followed.

The firelight illuminated the cave, Lu Feng's eyes looked around the cave, and found that the area of this cave was really not small, in the cave, rocks and weeds could be seen everywhere, and there were some red hairs left on the weeds.

Su Yumo looked at those hairs, frowned lightly, and said, "This should be the residence of the Fire Demon Ape King." ”

Lu Feng nodded in agreement, but apart from these, there were bare mountain walls around, and there was nothing else.

His eyes looked at Su Yumo, signaling if he had found anything, Su Yumo also shook his head in frustration after walking around the cave, obviously he didn't find anything, which made Lu Feng's brows furrow.

He believed that the Fire Demon Ape King's Neidan would definitely not guide him here for no reason, and the smell outside the cave just now was clearly the Xuanyuan Milk in the center of the earth, but it was very ordinary to enter the cave at this moment, what was going on?

Lu Feng's gaze scanned back and forth in the cave, and at this moment, his gaze stayed on a corner under the mountain wall, where the ground seemed to be a little uneven, and the ground was covered with the branches and leaves of the trees and the hair of the Fire Demon Ape King.

With a suspicious gaze, Lu Feng walked over, and then the palm wind howled, blowing away all the debris on the ground.

Without the cover of these debris, this piece of ground was completely exposed in front of Lu Feng's eyes, and he saw that there was a mud pit four or five zhang large, and the pit was obviously made recently, as if it was hiding something.

After a moment of silence, the energy in Lu Feng's body gushed out, and then an energy beam slammed into the pit ground.

"Boom!"

With a dull sound, a huge hole appeared in front of Lu Feng's eyes, and when Lu Feng saw this, a smile appeared on his face.

"Wow, there is really a mystery here, I didn't expect you to have the talent of treasure hunting!" Su Yumo exclaimed.

Lu Feng didn't talk, just smiled and asked, "I'm going down to have a look, do you want to stay here?" ”

Su Yumo immediately grabbed Lu Feng's shirt and said, "Of course I have to go down with you, in case something happens, I can still protect you!" ”

When Lu Feng heard this, he sighed secretly, this protection, I don't know who is protecting whom?

"Follow me!"

When the words fell, Lu Feng jumped down, and Su Yumo also jumped down.

When the two jumped under the pit, they found that there was a long passage below, because they were worried that there was still a hidden crisis in the passage, so Lu Feng and Su Yumo were still very cautious, which also caused the speed of the two to not travel too fast.

After walking through the zigzag passage and walking for about half a pillar of incense, Lu Feng suddenly found that at the end of the passage, there seemed to be a white light flickering, and the pace of the two of them also accelerated a lot.

After a while, the two finally walked to the end of the passage, and the flickering white light was also completely appeared in front of the two.

When they saw the source of the cluster of white light, the expressions of the two of them were instantly stunned.
