But now because they saw Yuan Yi and Lu Changan go to the altar, most of the demons rushed to Lu Changan's side, so Yuan Yi was a little unbearable alone.

"Master, have you found it? I can't hold on anymore, there are too many of them, they have surrounded us inside, and the rescue from outside can't come in at all. Yuan Yi looked at the more and more demons around him, swung his sword over and cut off a sword stabbed by the demons, and said anxiously to Lu Changan.

"Yuan Yi, be careful!" Lu Changan heard Yuan Yi's voice, took the time to look in the direction of Yuan Yi, and just saw a demon clan sneak attack from Yuan Yi's side while Yuan Yi was unprepared, Lu Changan was shocked, and subconsciously shouted.

At the same time as he shouted, Lu Changan had already flown out, and the Tianji Sword suddenly appeared in his hand, and he flew towards Yuan Yi's direction, and in the blink of an eye, he picked up his sword before the demon's long sword stabbed Yuan Yi.

Lu Changan pulled Yuan Yi and retreated towards the center of the altar, and the two of them looked back to back at the demon soldiers who came from all around, and their eyes couldn't help but become a little solemn.

"Master, have you found the mechanism?" Yuan Yi swallowed, and then turned his head sideways to Lu Changan behind him and asked.

Lu Changan was silent for two seconds, and then said, "No." ”

"Then what should we do now? Although most of these demon soldiers only have the cultivation of the Red Dust Fairy, they are also afraid of biting when there are many lice, so many of them come at once, it should be a little difficult for the two of us to deal with them alone. Yuan Yi had actually guessed the result, after all, if he had found it, then the two of them would not have been besieged by the demons on the altar now.

"Hold on, wait for the Dao Leader to put pressure on them from the outside, and we'll look for it on the altar. Lu Changan's eyebrows seemed to be twisted together, he didn't know what he was thinking, and even his reply to Yuan Yi's words seemed a little absent-minded.

"It seems that this is the only way to do it now...... Yuan Yi stared around nervously, and responded a little helplessly, saying that the atmosphere seemed to be a little wrong when he saw Lu Changan, and he couldn't help but turn his head and glance at Lu Changan. "Master, what are you thinking? But have you found anything?"

Lu Changan's eyes were staring at the altar under his feet at this time, and he didn't react to Yuan Yi's words at all. Yuan Yi saw that Lu Changan didn't speak for a long time, so he couldn't help but look at Lu Changan again. happened to see a demonic qi shooting from his direction, so he hurriedly dragged Lu Changan to dodge.

After dodging this demonic aura, Lu Changan also came back to his senses from his thoughts, and looked at Yuan Yi, who was scared, and hurriedly cast a grateful look.

Yuan Yi wanted to say something, but Lu Changan broke away from Yuan Yi's hand and went straight back to where he was standing just now. Seeing the demons constantly rushing around, Yuan Yi shrugged his shoulders, and then continued to be a bodyguard with some helplessness.

There was no way, Lu Changan seemed to be stunned, and he didn't know whether he trusted Yuan Yi or was really attracted by something, as if he didn't see the demons attacking around him, he walked straight towards the place where he was just standing.

Therefore, Yuan Yi had no choice but to continue to help Lu Changan open the way, and stop all the demons who attacked Lu Changan, so that they could not get close to Lu Changan.

Lu Changan came to the place where he was standing before, then squatted down and touched the ground on the altar with his hand. Because most of the altar is made of bones, although the floor of the altar is not patterned, the arrangement and combination of those bones form a different pattern.

Yuan Yi came to Lu Changan's side, pinched a few spells in his hands, and then slowly raised his palms from the dantian to the position of his chest, and then flipped upwards suddenly, and his hands turned into palms facing the sky.

A stream of true qi also centered on Yuan Yi, slowly spreading from the mid-air facing Yuan Yi's palm, and then there was a ripple-like enchantment covering Yuan Yi and Lu Chang'an within a radius of about five meters.

Because there are too many demon soldiers, Yuan Yi will inevitably take care of this but not that, so in order to avoid being unable to stop the attack of individual demon soldiers, Yuan Yi simply gave up the attack and turned to defense.

He stood in place and kept this posture unchanged, but his head looked at Lu Changan, and asked a little anxiously, "Master, what did you find?"

Lu Changan touched the bones embedded in the ground, his eyes narrowed slightly, and if the bones on the ground were connected, they would look like gossip patterns. The teleportation arrays on the first two layers are all related to Taiji, so Lu Changan has been looking for Taiji Diagram just now, but he ignores that the pattern of this bone arrangement is actually a pattern of Bagua.

Lu Changan stretched out his left hand, his true qi condensed, and then slapped his palm on the skull in the middle of the gossip pattern on the ground. True Qi flowed from the skull as if water was flowing down a pipe, instantly flowing over the entire altar, passing over every bone in the blink of an eye.

When True Qi traveled around the altar for a week, the top of the altar suddenly changed, and the feet of Lu Changan and Yuan Yi seemed to have turned into a huge whirlpool. The two of them were weightless, and before they could react, they both fell into the whirlpool.

When they opened their eyes again, Lu Changan and the others had already arrived in another place. And on the altar just now, Lu Changan and Yuan Yi have long since disappeared. Those demon clans who just wanted to attack looked at each other one by one, then frowned, and changed their direction one after another, turning to attack the other Tianyan Sect disciples and demon clan people outside the altar.

The fourth level is not something they can pass, although this Nine Turns Heavenly Demon Tower has been transformed by the ancestors of the demon clan, but there are still some forces that are harmful to the demon body's body and demon qi, so they can only stay in different tower layers according to their strength, and no matter how high they are, they can't go up.

Now that Lu Changan and the others have gone to the fourth layer, it is not for them to organize, and they have the difficulties of the fourth layer to stop them.

At this time, Lu Changan and Yuan Yi, who had reached the fourth floor, were staring blankly at everything they saw in front of them. If it weren't for what they saw and experienced with their own eyes, it is estimated that they would not believe that they were staying in the tower, and they might all directly think that they had gone to hell.

The place they were in now looked like a large cave, and the place where they were was was a cliff, and the cliff side of the cliff was Lu Changan, and behind them was a teleportation array shaped like a cave, and it was from there that they had just passed to get here.

And in front of them is an abyss, and beneath the abyss is hot magma. Above the abyss, where they were connected to the cliff, there was a chain bridge, and the long chains of handrails on both sides of the bridge were full of bells.
