Chu Feng followed the sound, looking at the pale leaves left in the mud block that Lu Chenxi was holding in his hand, and couldn't help but show a look of surprise.

This was the first time he had seen a fragment of a plant since he came to the Underworld, and thanks to the thoroughly hardened soil that wrapped the leaf, he was afraid that it would have disappeared long ago.

That fragment is very small, but the size of a finger, if you are not careful, it is easy to ignore the past, if it is not for Lu Chenxi to examine it carefully, I am afraid that it has already been overlooked.

Chu Feng took the mud block, silently looked at the fragments that had been cut off from the leaves of some unknown plant, and carefully recalled that the leaves of any plant also looked exactly the same as this plant.

The pattern of the leaves on the fragment is very peculiar, showing an unconventional grid, as if it has been artificially defined, and each stripe is very fine and neat, without the slightest deformation.

Chu Feng was silent and frowned.

He remembered a plant with which he had a deep connection.

"Do you recognize it?" Shen asked Si.

Chu Feng pursed his lips and said, "I have seen a plant with such lines on its leaves, but it doesn't have complete leaves and plants, and I'm a little unconvinced." ”

The leaves of that plant will also exhibit such characteristics, but ...... It is not necessarily the only plant that has such characteristics.

Maybe there are other plant leaves that will have such characteristics, even if Chu Feng already has a result in his heart, but if there is no complete leaf, Chu Feng does not dare to easily conclude that the leaf fragment in his hand comes from that plant.

It's just that there is a strong intuition that tells Chu Feng that the fragments in his hand do come from that one plant.

"Tell me what kind of plant it is. Cooker Yan pursed his lips and asked.

"Senior brother, let's talk about it first, whether it is or not, maybe it will help. Lu Qi also replied.

Chu Feng smiled, but his smile was obviously a little reluctant, and the look of shock in his eyes was undoubtedly exposed if he couldn't hide it at all.

"You should have heard of Nalingen. Chu Feng said.

"Of course I know, Nalinggen will absorb all the spiritual energy within a radius of tens of miles, destroying the leylines. She paused, then her eyes widened and she said, "You mean it'...... Nalingen?"

Chu Feng nodded and said, "I think...... It is the Nengen. ”

The Nalinggen is a plant that needs the support of strong leylines to grow, and where it is born means that the leylines are strong - otherwise, the nearby aura will be sucked away and the leylines will not be able to recover for a short time.

But where the Na Linggen grows, within a radius of tens or even hundreds of miles, it will become a barren, and the more plants that need the nourishment of the aura, the more difficult it is to survive, because on top of the competition for the aura, they will not be the opponent of the Na Linggen at all, and it is precisely for this reason that the Na Linggen is called the abyss of the aura.

Because of its medicinal properties, it is difficult to enter the medicine, and ordinary monks do not dare to touch the Naling root at all, after all, it is a force that cannot be mastered at all.

And during the time when Chu Feng's sea of qi was melting, Chu Feng struggled to survive with the medicinal power of Naling Root.

During that period of time, Chu Feng's cognition of Nalinggen had almost reached a considerable height, which was not at all something that ordinary people could understand.

It was precisely because of this that Chu Feng remembered every detail of Nalingen, the moment he put the fragment into his hand and saw it clearly, he had already recognized it, this fragment was very consistent with the blade of Nalinggen.

Chu Feng frowned, looked at Lu Chenxi and asked, "Where did you find this?"

"Chenxi was very careful to find it in its mouth. Shen Fangsi pointed to the skeleton at Lu Chenxi's feet.

Chu Feng was slightly stunned, squatted down, and briefly examined the corpse before shaking his head and said: "This is the most common racial bone in the underworld, judging from the old color of the bones, I am afraid that it has been dead for hundreds of years, and there are still some large soil particles between the bones, and the land here is compacted and windless, and it can't blow such large soil particles at all, so I think this corpse should have climbed up from the ground and came here." ”

"Does that help the current situation?" asked Cooker.

Chu Feng shook his head and said, "Keep looking, pay attention to the mouths of these corpses, I want to see how many more such clods of soil can be found." If you can, you can even dig up the earth, which I think is likely to come into its mouth after it died. ”

Several people did not veto Chu Feng's opinion, after all, on this matter, Chu Feng was still more credible than them.

The rest of the night was spent scrutinizing the bones and digging up the ground, and although the results were not much, they did gradually unearth some fragments of plants that had been wrapped in clods of earth and remained.

With a considerable amount of plant fragments and branches, Chu Feng was naturally able to further verify his speculation - his previous speculation was not wrong, these plants did come from Nalinggen.

Root fragments, stem and leaf fragments, all the fragments are perfectly in line with Chu Feng's perception of Naling Root, except for Naling Root, Chu Feng really can't think of any other plants.

Although the underworld could naturally grow a spirit root like the Six Realms, for some reason, Chu Feng remembered in his heart that on the island of the Shark Clan, the person who needed the cooperation of the Tree God and Yan Qingyu to stop it might not be able to stop it.

Does he have anything to do with the Underworld?

How can we solve these entangled mysteries?

Chu Feng didn't know, and the young people present naturally wouldn't know, but Chu Feng had a hunch that the more mysteries, the more complicated they became, and the originally unrelated mysteries might be implicated in each other, maybe solving a certain mystery could solve the entire network of mysteries.

Although he couldn't see where the hope was yet, Chu Feng believed that this mystery would not be hidden for too long, and the day of uncovering it was getting closer and closer.

Although several people have this gain, but other than that, there is no other gain.

Several people fell into silence, now this side of the world, in addition to the place of the living and dead, and the seal of the sea of flowers is the focus of attention, if there is no progress in the place of the living and dead, they can only choose to return to the location of the seal.

But even if they return to the location of the sea of flowers, their ability is only to watch, and if they want to get close to the seal and meddle in it, it is simply a matter of eating people and talking about dreams.

It is undoubtedly ironic for both sides that they are destined not to achieve greater results, but they still have to make some meaningless choices.

Therefore, several people were a little silent, and they all fell into thought, thinking about what to do next.

Chu Feng also felt a deep sense of powerlessness at this time, and he suddenly felt that Li Changchuan and the others might not have been wrong in their judgment at that time, they were no longer able to meddle in this matter, and all they might be able to do was to wait for a result.

Chu Feng let out a long sigh.

Lu Qi said, "I think...... We can go to the other side and have a look. ”

"On the other side?" Chu Feng frowned, on the other side, in addition to the nine ancient wells, there was also the high platform.

There is a strange river on the high platform, and a wooden bridge...... There was also an ancient large formation that he didn't know what kind of formation it was

Chu Feng was suddenly stunned, because a red river and a wooden bridge seemed to be too many times in the underworld.

The depths of the seal and the entrance were red rivers with a wooden bridge that reminded him of the Seven Passes.

There was a red river on the high platform of the opposite world, and above the river there was also a wooden bridge that reminded him of the seven levels.

Is all this really just a coincidence?

Chu Feng frowned, his eyes revealing some doubt.

"The rift leading to that side is entrenched by dragons, and it is impossible to get through. Cooker Smoke emphasized.

"At the very least, you can give it a try. Chu Feng suddenly spoke, his expression was very firm. He thought it necessary to go to the other side, especially on the high platform, because that was the last key, the last point they knew.

"What do you think of Chenxi?" Guli asked as he looked at Lu Chenxi.

Hearing this, Lu Chenxi raised his head, glanced at Chu Feng, and then nodded, "Yes." ”

Shen Fangsi also narrowed his eyes and laughed: "Even if it is a dying struggle, it is better than waiting to die!"

Yi Yan snorted coldly, pouted and said, "Anyway, you people listen to you more." ”

Gu Li pondered for a moment before he said, "Although it is worth a try, I am afraid that the danger in it will not be much less than breaking into the seal." ”

"Do you want to do it separately?" Shen Fang pondered for a moment.

Although Guri was a little embarrassed, he still nodded and said, "But it's not completely separated, but the whole team is divided into two halves, and the back team follows the front team." ”

"Stone-throwing. Lu Chenxi said.

"Ask for directions. Chu Feng nodded in agreement with Gu Li's proposal, and by the way, he supplemented Lu Chenxi's words completely.

"Just the one who opens the way ahead......" groaned Guriri.

"I'll go with Chu Feng. Shen Fangsi opened his mouth and said, "I have a ghost and god suit, and I should be stronger than all of you in terms of defense." ”

Chu Feng also nodded.

"I mean, he just doesn't start. Guri laughed, "After all, sir's ...... Profound knowledge is extremely important to us at this time. ”

Chu Feng couldn't help but smile, he knew that Gu Li actually wanted to say that his cultivation had not yet reached the peak of the ninth order, and it would be a little dangerous if he rushed to the forefront.

"He's the fastest, no slower than the wind of the flawed side. Lu Qi said, and then looked at Chu Feng and laughed.

Chu Feng also smiled, once the extreme speed of the Wind Riding Technique was unfolded, he had enough confidence to ensure his safety.

"That'...... So be it. Gu Li glanced at Lu Chenxi, and got the confirmation information from Lu Chenxi's gaze, so he no longer insisted;
