"Senior, who is Luo Yan, who seems to have had a holiday with the senior?" asked Xiao Bai and Lang Yao after leaving the safe area.

"That Luo Yan is a Terran monk in the middle of the Jindan period, I fought with him a lot when the rules were not established before, and it was natural to see the other party unpleasantly when I fought more, but that person's one-handed fire control technique was superb, and it was very difficult to deal with. Lang Yao said.

The two of them left the safe area and ran all the way, Lang Yao had been extremely familiar with this fourth layer in the past twenty years, and he had not encountered any major trouble along the way.

"In about an hour it will be dawn, and then you will be able to rest. Lang Yao said and dodged a thick branch, who knew that this branch was much faster than the other branches, and after Lang Yao dodged it, it quickly came to him, and immediately entangled Lang Yao, who was caught off guard.

"Oh no! There's a tree here that's morphed into a giant tree. After Lang Yao was entangled, he kept attacking this thick branch, but it was to no avail, the tenacity of this branch was often entangled, and he couldn't get out, and he couldn't break it off.

"Senior!" Xiao Bai saw that Lang Yao was entangled by the branches, and immediately rushed forward, the wind blades slashed on the branches one after another, and the branches that hit trembled for a while, but refused to let Lang Yao go.

Looking at Lang Yao who was dragged towards the giant tree little by little, Xiao Bai was a little anxious in his heart, he watched Lang Qing die beside him before, but now he wants to watch Lang Yao die? Xiao Bai thought of Lang Qing's appearance when he was dying, and his spirit was in a trance, and he was actually entangled by that branch.

"Xiaobai!" Lang Yao shouted as he looked at Xiao Bai, who was standing still, as he struggled.

Xiao Bai was shocked by Lang Yao's roar, and when he looked down, he saw the branches wrapped around his body, and the natural supernatural power in his body was unconsciously released, who knew that this natural supernatural power had an unexpected effect, and the branches that were originally wrapped around Xiaobai's body turned into ashes and disappeared in an instant. Xiao Bai was surprised for a while, why could this branch be dispelled by the innate supernatural power? Xiao Bai glanced up at Lang Yao, his body rushed towards Lang Yao, and the innate supernatural power continued to activate, and grabbed the branch that entwined Lang Yao, this branch turned into ashes as soon as it was touched by Xiao Bai, and the branch wrapped around Lang Yao's body could no longer exist after being separated from the body, and also turned into ashes.

The two didn't dare to delay, as soon as Fang got out, he immediately left the attack range of the giant tree, Lang Yao looked at Xiao Bai in disbelief and didn't know what to say. In the past twenty years, he has been cautious, he has never been attacked by tree branches, and he has never encountered a tree that suddenly evolved before.

"Xiaobai, what was it just now?" Lang Yao asked as he looked at Xiaobai.

"Wait a minute, I have some ideas, but I still need to confirm them. Xiao Bai put away his natural powers, walked to an ordinary tree and wrapped himself around the branches of this tree, Xiao Bai observed carefully, his body was full of dispersal power all the time, but this branch only wound itself and did not inject any power into the body, so this branch did not touch the power of dispersal in the body, and when the branch pulled itself to the trunk, Xiao Bai felt a suction to suck the vitality in his body, and a liquid was secreted from the trunk, which dissolved the contact place as soon as it touched Xiaobai's clothes。 Xiao Bai pressed the trunk with both hands, and the dispersal power in his body was frantically injected into the trunk, only to see that the tree trembled, and the branches that were originally wrapped around Xiao Bai threw Xiao Bai out at once.

"Xiaobai, what's going on?" asked Lang Yao as he ran to Xiaobai's side, looking at the trembling trees.

Before Xiaobai could answer, the tree shattered piece by piece in a trembling manner, and the fragments were scattered into the air and were disintegrated, and after a while, the entire tree disappeared completely.

"This..."Lang Yao had never seen such a scene in twenty years, and it was also the first time he had seen someone alive after being entangled in a branch.

"I know what it is, it's not a tree, it's a spirit. Xiaobai said.

"Spirit, the spirit formed by the condensation of the vitality of heaven and earth gives birth to spiritual wisdom?" asked Lang Yao rhetorically.

Heaven and earth vitality is divided into different attributes, such as fire, water, thunder, etc., spirit, is born from the heaven and earth vitality, the birth of the beginning of the spiritual wisdom, but most of the spiritual wisdom is not high, with the continuous cultivation of strength is getting stronger and stronger, the spiritual wisdom is also getting higher and higher, the advanced spirit is no different from people, but the spirit is extremely difficult to be born, I did not expect that this fourth layer of the forest world turned out to be a world of wood spirits.

As for why the branches of this tree cannot be cut off, it is because the entire fourth layer is filled with a large amount of wood attribute heaven and earth vitality, and everyone is not unable to cut off this branch, but the connection between this branch and the body is cut off, and after the cut, the branch instantly returns to its original state, and the recovery speed is so fast that no one can detect it, so naturally they think that it cannot be cut off.

"I have never seen a spirit before, but I have heard people say that this spirit is the vitality of heaven and earth, because it is constantly changing between the virtual and the real, and it is extremely difficult to kill. Could it be that this fourth layer is actually a world of wood spirits?" Although Lang Yao listened to Xiao Bai's explanation, he still felt a little incredible.

"I think so, I've never seen it, but I think so. Although I don't know why this fourth layer is like this, it should have a great relationship with this heavenly tower, when I was entangled by the branches, I felt that the vitality in my body was absorbed, and when I was close to the trunk, a liquid was secreted from the trunk to corrode the clothes, thinking that this tree is not sucking the flesh and blood of others, but absorbing the vitality in the body of others to strengthen itself, and the body of the entangled person turned into blood and disappeared should be corroded by the liquid. Xiaobai continued to explain.

Xiao Bai told Lang Yao what he guessed, as for why he was able to destroy this wood spirit, he didn't tell Lang Yao, Lang Yao didn't ask again when he saw that Xiao Bai didn't say anything, knowing that this was a secret in Xiao Bai's cultivation, he was naturally not easy to explore.

"It should be so, this Heavenly Tower was built by the big people in the Heavenly Palace, and it is not surprising that there is anything strange about it. Such a tactic is indeed unheard of. Lang Yao believed Xiaobai's statement and sighed.

"Senior, I said that there is a tree king in the area at the back of this fourth layer, I want to go and see, can I help lead the way?" Xiaobai said.

"What? That Tree King is a cultivator in the late stage of transformation, and the whole is even more obscured, although I don't know what method you use, but kill the wood spirit, but it's better not to go and send it to death. Lang Yao couldn't see Xiao Bai's cultivation realm, thinking that since Xiao Bai was imprisoned in the fourth layer, he was naturally a cultivator in the middle stage of transformation, although he knew that Xiao Bai had a way to kill Mu Ling, but he still didn't think that Xiao Bai was the opponent of the Tree King.

"I know the concerns of my predecessors, but seniors, I am not a mid-transfiguration monk, and the appearance of me that my predecessors see now is not something that I changed by the method of change. Xiaobai looked at Lang Yao and said.

"You mean, you are the pinnacle of transformation?" Lang Yao looked at Xiao Bai in shock.

"Yes, senior!" Xiaobai nodded in praise.

"Then since you are the peak of transformation, why are you imprisoned in this fourth layer?" asked Lang Yao.

"Senior! I wasn't imprisoned in this fourth layer, Ah Qing and I were injured by the Angel Patrol and then taken back to the Heavenly Tower, it was the Angel Patrol who locked us in the Heavenly Tower, and the prisoners were naturally done by the subordinates of the Angel Patroller, if nothing big happened, the Angel Patrol should not have paid attention to this matter, plus no one could go out if they were locked in the Heavenly Tower, the Angel Patrol should have opened the Heavenly Sealing Tower and locked me and Ah Qing into the first floor, and I came to this fourth layer from one floor to another。 Xiao Bai told Lang Yao how he came to the fourth layer.

"How did you get down layer by layer?" Lang Yao had been on this fourth floor for nearly twenty years, and he had never seen anyone enter like this, and knowing how to go to other layers meant that he could escape from this Heavenly Tower.

"There was a kind of light curtain passage in the previous floors, and when you entered the light curtain passage, you could go to the next floor, but you could only go down, not up. Xiaobai replied.

"I've been on the fourth layer for nearly twenty years, and I've never seen your Shuo's light curtain passage, if it really exists, then it must be in that tree king's place, and no one dares to go to that place for so many years. If there is any secret that no one knows about this fourth layer, it must be there. Lang Yao looked at Xiaobai with an inexplicable look of excitement.

"Okay, let's go to the tree king's place, let's go!" Lang Yao said and rushed to the center of the fourth floor with Xiaobai.
