Chatting and chatting, the two finally walked to the bottom of the black tower, there are four arched doors on the first floor are located in the southeast and northwest directions of the tower, the door here is not guarded, the two walked directly in, there is a huge column in the middle of the huge tower, it takes about twenty people to hold it hand in hand, this column also has four doors, but it is square, there are queues outside the four doors, there are not many people, as if waiting for something, the man took Zhu Xuanchen to stand in a team of relatively few people, and there are many tables and chairs on the wall of this hall for people to talk and rest。

It didn't take long for the door in front of Zhu Xuanchen to open automatically, the door opened from the bottom to the top, and there were eight people standing in the door, these eight people quickly walked out when they saw that the door was completely open, and then the people outside the door walked in in an orderly manner...... Every time one person enters, one is added, "Daoyou, this is...... Eh~" He pointed to the door and just wanted to ask what this number was for, Zhu Xuanchen was pulled in by the captain, and said as the captain walked, "Let's talk about it first." ”

After Zhu Xuanchen went in, he turned around and saw that the people behind him were all looking at him with dissatisfaction, it seemed that he was blocking the people behind him when he was in a daze just now, and the people looked at him indignantly, and Zhu Xuanchen looked embarrassed under the black curtain hat, thinking that it seemed that he was making a fool of himself again.

However, following the old naughty boy Xuanhuang for a long time, his face is naturally a lot thicker, not to mention that there is a black curtain hat covering others who can't see his face, so he was embarrassed for a while, and then he began to observe the surroundings curiously, only to see that there was a large black swarthy swarthy slate on the top of his head and under his feet, and the middle of the two slate was a white hard metal connected together, they were like a hollow part of the bamboo, but a gate was opened in front, he stretched out his hand and touched the wall, feeling that there was a certain formation fluctuation on it.

At this time, the captain said to him with his divine sense: " This thing we are standing on now is called the magnetic ladder, as the name suggests, it is to use the power of the magnets between each other so that we can easily and quickly reach any tower floor, the number you see outside is the number of people who can be counted by the magnetic ladder, the magnetic ladder can only transport up to ten people at a time, and the magnetic ladder will automatically close the door when it reaches ten people, and the two stone slabs under our feet and above our heads are big magnets, and the bottom and top of the magnetic ladder each have a magnet that is larger than this, and the power of the magnet can be artificially controlled through the control of the spiritual power of the formation. ”

After hearing this, Zhu Xuanchen nodded in surprise and said with his divine sense: "It's really ingenious! I don't know who actually came up with such a magical and convenient thing, but how to make the magnetic ladder stop on the tower floor where you want to stop?"

When Zhu Xuanchen finished saying this, the magnetic ladder really closed the door after ten people entered, and began to rise straight and fast.

The captain said with a slightly proud expression on his face: " You look up at the nine-square grid number on the door, the nine numbers are used to enter the number of tower floors you want to go to, touch it lightly with your divine sense, and the number that keeps adding up next to it represents the tower layer we are in, for example, we are going to the ninety-fifth floor now, and directly use the divine sense to convey the tower layer you want to go to, each tower layer has a different numbered induction array at the entrance of the magnetic ladder, when the magnetic ladder comes to the tower floor that someone wants to go to in the magnetic ladder, this formation can make the magnetic force up and down the magnetic ladder to achieve balance, and it can stop smoothly at the entrance of the tower floor, I only know these, and I am not very clear about the other specificsThere are a total of ninety-nine floors in this black tower, and if there is no magnetic ladder, I don't know how long it will take to go up from the first floor to ninety-nine. ”

Zhu Xuanchen nodded and said: "Well, indeed, no wonder they are not afraid of trouble to build such a tall giant tower, it turns out to be a convenient tool, by the way, I also want to ask a question, that is, why there are no buildings in the city except for these three giant towers, where should that person live?

"That's right, in addition to the first floor in the tower, there are one hundred and eight houses on each floor of the other towers for people to live in, how many houses are enough, and the top ten floors are inhabited by some core personnel belonging to the Chaos City, and the following are ordinary cultivators who live, so non-core personnel can't go above the eighty-ninth floor casually, otherwise they will be severely punished, and the place responsible for receiving new cultivators is on the ninety-fifth floor, otherwise even I can't go there casually." The captain said slowly.

Gradually, the people in the magnetic ladder were gone, only the two of them were left, after all, there were very few people who wanted to go to the ninety-fifth floor, and it didn't take long for them to reach the ninety-fifth floor, the door of the magnetic ladder slowly opened, different from the entrances of other tower floors, there were two more guards at the entrance of this floor, the man next to Zhu Xuanchen walked out, and after explaining the situation to them, the man turned around and beckoned to him, signaling that he could come out.

But just when Zhu Xuanchen had just taken a few steps out, one of the guards suddenly said, "The newcomer, take off your hat, otherwise please go back and forth from there." ”

Hearing this, Zhu Xuanchen was shocked in his heart, and sighed in his heart that he really escaped from the first fifteenth year, and when he was hesitating whether to reveal his true face or go back to find a way, the guard saw that he was grinding and became even more suspicious, and shouted: "Who the hell are you? Take off the hat, or go out quickly! If we try to do it again, we will do it!" As he spoke, he took out a short stick and looked at Zhu Xuanchen vigilantly.

Seeing this situation, Zhu Xuanchen could only turn around and walk back helplessly, but as soon as he took a step, he heard a person's voice behind him, "Why are you so alarmed?", the voice was very peaceful, and it sounded like an old man's voice.

Hearing this voice, the four of them all looked in the direction of the voice, and an old man in a gold-rimmed black robe was standing there with a kind smile on his face, and the guard and the captain immediately bowed and shouted respectfully, "Elder Ouyang." ”

"Get up and tell me what's going on?" Elder Ouyang asked softly.

So the guard told the old man what happened, and the old man looked deeply at Zhu Xuanchen for a few seconds after listening, and then showed an inscrutable smile to Zhu Xuanchen, and then said to the guards: "Well, I understand, leave this person to me, don't drive away the newcomer privately when you encounter this kind of thing in the future, do you want to report it to your captain?"

"Well, I know Elder Ouyang. The guard nodded hurriedly.

Then Elder Ouyang beckoned to Zhu Xuanchen and said softly with a smile, "Come with me, young man." ”

Originally, Zhu Xuanchen planned to turn around and leave immediately, but Elder Ouyang's voice seemed to have magical power, dispelling his desire to go back, so he slowly walked towards the old man.
