After confirming the identities of the ten people, the Mohist disciples opened the door of the Tianji Tower. Everyone saw only a dark passage for two people to walk side by side, but nothing could be seen inside. The peeps were not satisfied, and everyone couldn't help feeling a little jealous.

Sigh, but some people have started new speculations, wondering how dangerous it is inside this secret building. And people from their own sect who have entered are even more relieved and worried at the same time.

Yan Luo looked deeply at Tang Luo, who smiled sweetly in return. With his mind right, Yan Luo turned around and followed the people in front of him, striding into the door of Tianji Tower.

Su Wen, who was behind Yan Luo, also turned her head and looked back, but not at Tang Luo, nor at the phantom who was looking eagerly at them. What she saw in her eyes was Xia Qingcang's figure dressed in black and standing with his hands behind his back.

Of course, this was just what she was thinking. At the moment, he was fighting against the ghost clan, and he didn't know how difficult it was!

Raising her head, Su Wen took a deep breath, turned around and strode back to Tianji Tower. Just missing him was of no help. Now she could only find the four guardians as soon as possible before she could find him.

Ten people walked into the copper-made passage. As soon as the door of the Tianji Building closed behind them, candles were automatically lit in the passage. Feng Jiuge took the lead and walked at the front. He strode forward without worrying about any traps in the passage.

He was so confident that the others were happy to let him be the vanguard. They carefully followed him one by one and walked slowly into the passage. The passage that was enough for the two of them to walk side by side was only less than two feet away. Soon, they were in front of them.

It opened up, and they officially arrived at the first floor of the Tianji Building.

Feng Jiuge's body stopped at the exit of the passage, he put his hands behind his hands and glanced at the ground in front of him, then stepped out without even a moment's hesitation.

"Don't move!" Mo Xuan stopped the person who was following Feng Jiuge and was about to go up. But his eyes were looking in the direction of Feng Jiuge. In the meantime, Feng Jiuge had already stepped into the Nine Palaces Formation. He did not hesitate to take a step.

A square stone brick, after thirty-three steps, came out of the nine-square grid formation and stood on the opposite side. "Only one person can pass, one person at a time. After he passes, the nine-square grid position changes, and the next person must untie it by himself before he can pass."

With that said, Mo Xuan turned around and looked at Su Wen and others.

"why is it like this?"

"I can't do this!"

The remaining four people looked at each other and stood in front of the nine-square grid. Those who knew how to do it looked at the direction carefully and thought about the path. Those who didn't know how to do it, scratched their heads and looked at the others.

Mo Xuan approached, Su Wen and others gathered around, Mo Xuan looked at everyone with questioning eyes.

Yama shook his head.

Li Zhu said coldly, "No."

Lan Ziqian nodded slightly, he could still do this simplest nine-square grid.

Su Wen nodded. She had learned some five-element formations but was not proficient in them, but she could still get through the nine-square grid.

"Okay!" Mo Xuan nodded, turned around and stepped forward. Su Wen and others followed him. He took a look at the current position of the Jiugongge, turned around and whispered to Yan Luo, who nodded and stepped onto the square brick together. The same thing happened.

Thirty-three steps later, the order of steps was completely different. Yama successfully reached the opposite side and stood at the exit waiting for them.

As soon as Yama walked by, the nine square tiles on the ground changed rapidly and formed another wave. Mo Xuan smiled slightly and whispered a few words to Li Zhu. Li Zhu had a cold face and did as Mo Xuan said, after thirty-three steps

, also go to the opposite side.

The two of them passed by, Su Wen, Lan Ziqian also passed by, and Mo Xuan was the last one to pass with a smile. The four people were left behind, looking at them with unwillingness.

After Su Wen and the other five people passed through the Nine Palaces, they walked into another room together, only to see an old man in Mohist attire sitting in front of a large square table in the middle of the room, his face as expressionless as a sculpture. Feng Jiu was the first to go in.

Ge was standing on this side of the square table, looking down at the imitation surface, thinking deeply.

When Su Wen and others approached, they saw that there was a very complicated arithmetic problem on Dafang's table. Su Wen and the other four could hardly understand it. Only Mo Xuan took a look at it and smiled.

When Su Wen saw him smiling, he knew that this question would not trouble him, but there was only this big square table here, and the old man who looked like a sculpture must be the gatekeeper of this floor. Their arithmetic question was the first

I don't know if I can pass the level by solving this problem, or if everyone needs to solve one problem.

"Only this question." Mo Xuan smiled lightly, took out the folding fan from his arms, and asked Su softly: "The square table has no mechanism and cannot be changed. This question is the king of arithmetic."

"Can you solve it?" Lan Ziqian looked at the dense arithmetic problems. To be honest, his head started to feel dizzy.

"No need, Feng Jiuge will definitely be able to solve it after just one stick of incense. Let's just follow him." Lan Ziqian could clearly see the numbers written by Feng Jiuge and knew that he was very knowledgeable about arithmetic.

, he can definitely solve this problem.

"That's good." Lan Ziqian nodded and stopped looking at the numbers to avoid getting dizzy.

Yan Luo stood behind Su Wen on the right side, fully on guard, without uttering a single glance, waiting for what Su Wen would say or what he would do.

Li Zhu folded his arms and stood behind Su Wen to the left with a cold expression. He had not read the question at all.

"This Feng Jiuge..." Su Wen frowned and looked at Feng Jiuge, who was writing and drawing with his head down at the square table. For some reason, he just felt that this person was not simple. His martial arts and abilities, after two rounds of competition, and

The Jiugongge and the current arithmetic problems have shown that he is definitely not a simple person. Everyone can see this.

What she cares about is his purpose. Everyone who comes to Mo's house is for Tianjijuan, but this Feng Jiuge, for some reason, she just has a feeling that he doesn't seem to be here for Tianjijuan, at least, not just for Tianjijuan.

He came here for the secret scroll. He must have other purposes!

In the competition the day before, he kept his appearance, sitting in his position, condensing all his aura, and hiding all his presence. If it was because Tianji Juan had too many powerful enemies and hid his strength, that would be true. But the second

On the second day, he defeated the eldest disciple of the Nangong family in ten moves. Such publicity was in huge contrast with the efforts to hide it on the first day. Why was this?

After entering the Tianji Tower, he has been walking at the front, and his eagerness is not hidden, and it is quite obvious. And in the passage, he does not worry at all about the traps, which shows that he has a certain understanding of the Tianji Tower and the Nine Palaces Grid.

, the arithmetic problems seemed to be within his expectations. He had already shaken his head and was fully prepared, and calmly responded to and answered the questions. These further showed that he had some prior understanding of the Tianji Tower.

This person is not simple, his ability is not simple, his person is not simple, and the purpose of entering Tianji Tower is not simple!

Mo Xuan stood beside Su Wen all the time and did not miss the expression on Su Wen's face when he looked at Feng Jiuge. He also understood what she was thinking, because that was what he was thinking too. He slowly shook the folding fan twice, with a slight smile on his face, thinking

Su Wen shook his head and nodded again.
