Zhang Ju and the three of them stood in place, motionless, their eyes were firmly fixed on the stones on the ground, and the surroundings suddenly fell into a quiet, after a while, Su Ce was a little impatient and said: "Brother Ju, do you have any clue?" If I continue like this, I'll go crazy! ”

Zhang Ju looked thoughtful and didn't pay attention to Su Ce, and Xu Yuling next to him was also a little anxious, and then said, "Zhang Ju! Why don't you speak? ”

When Zhang Ju heard her words, he came back to his senses and said, "Were you talking just now?" ”

Su Ce and Xu Yuling nodded almost at the same time, and Xu Yuling immediately spoke: "You were so serious just now, you ignored us!" ”

Zhang Ju was a little embarrassed and said: "I thought of some possibilities just now, but when you said this, my train of thought was interrupted." ”

Su Ce listened to his words and blurted out, "Brother Ju! What's the idea? Say it and analyze it! ”

"That's right, I was thinking just now, if the eighty-one floors on this ground are divided into nine parts, then each part is nine pieces, which happens to be a nine-square grid." Zhang Ju nodded slightly, opened his mouth and spoke.

Su Ce then asked, "And then?" ”

"Then I remembered the strange intervals of time I had in the labyrinth." Zhang Ju recalled.

"One, three, seven, nine?" Su Ce blurted out.

Zhang Ju nodded and continued, "That's right! I always felt that the mechanism here should be connected to the labyrinth, and we kept following the direction of Nine at that time, and finally got out of that labyrinth. It's just that here we can't determine the number of the nine-square grid, which is a troublesome thing. ”

Su Ce lowered his head and continued to look at the floor under his feet, carefully looked at the Jiugong grid where his feet were, still had no clue, turned his head to Zhang Ju and said, "I really can't see it, this floor is bare." ”

Xu Yuling, who was on the side, suddenly spoke: "At that time, those four numbers pointed in four directions, if you find an intersection in the nine-square grid, can you determine these numbers?" ”

"Yuling said very reasonably, how did I forget this, there can only be one cross in a nine-square grid." Zhang Ju blurted out as if he had been empowered.

Su Ce was a little puzzled: "It is true that there can only be one cross, but how to correspond the four numbers to the four directions?" ”

Zhang Ju shook his head and said: "This really can't be corresponded, but I think these numbers don't matter anymore, the direction of the maze represents both the entrance and the exit, maybe the cross in the nine-square grid here is used to guide the direction, in each nine-square grid, the floor at the four corners of the cross may be the direction." ”

As soon as he finished speaking, he took a step forward and stepped on the floor on the periphery of the nine-square grid under his feet, and after waiting for three seconds, the mechanism was not triggered, and he immediately spoke: "Sure enough, as long as you step on the four corners of that cross, you will not trigger the mechanism." ”

After Xu Yuling and Su Ce heard this, according to Zhang Ju's words, they began to try, and after a while, the three of them walked to the opposite side and saw the stone wall appear in front of them.

On the stone wall, there was no trace of the door, Su Ce said strangely: "No door, why don't you go to the left and right sides to take a look?" ”

Zhang Ju shook his head and said, "When I came here just now, I had already carefully looked at the stone walls on both sides, and there were no traces of doors on the stone walls. ”

Xu Yuling looked at the two of them and said, "Could it be that we are on the wrong path, and this is the end of this road?" ”

Zhang Ju looked at her and opened his mouth slightly: "Probably not, there is no need to go to great lengths to set up this kind of mechanism in such a place, right?" This is the way to the main burial chamber. ”

Su Ce was puzzled: "But there is no way out!" ”

Zhang Ju stared at the stone wall with his eyes and said, "Let's go over and take a look, I won't believe it!" ”

As soon as the words fell, he took the lead in penetrating, Xu Yuling and Su Ce were just about to go in, when they saw Zhang Ju retreating, the expression on his face was a little strange, he looked at the two of them, and blurted out: "It's all intact rock formations, there are no stone gates, and there are no roads, it's really strange!" ”

After hearing this, Su Ce said a little anxiously: "How is this good?" Why don't we go back the way we came, on the left and right! ”

Zhang Ju looked at Su Ce, his eyes were resolute, not like he wanted to return the same way, and then said: "There is no need to be like this, there should be an entrance in this tomb, it seems that we still need to study the nine-square grid, maybe the mechanism that opens the unknown entrance is in those nine-square grids." ”

Xu Yuling blurted out: "At that time, people can put the mechanism and entrance that hurt people together and control them with the same thing?" ”

"Don't underestimate the wisdom of the ancients, it's easy to suffer!" Zhang Ju replied.

Zhang Ju turned around, looked down at the eighty-one stones, and fell into deep thought, Su Ce and Xu Yuling saw this, stopped talking, and the surroundings suddenly fell into a quiet again.

At this time, the Ninth Master and his party came to the crossroads, and one of them looked at the situation in front of him and said, "Ninth Master, where are we going?" ”

After the Ninth Master looked around, his heart froze for a moment, and he said, "Go to the right hand, I've walked for so long, and the journey has been strangely smooth." ”

The man named Xiao Ding spoke: "Yes, but the Ninth Master, why do we have to go to the right?" ”

After thinking for two seconds, the Ninth Master spoke: "With my experience of fighting backwards for so many years, when I don't know where to go, I will go to the right. ”

The three of them nodded one after another, and the four of them turned around and walked to the right, the tomb on the right was in the shape of an arc, the stone walls on both sides were extremely smooth, and on the ground, there were square stone slabs carved into them.

After they walked for nearly two hundred meters like this, suddenly a gust of wind blew from the front, causing the four of them to tremble, Xiao Ding's face changed slightly, and blurted out: "Ninth Master, this wind is very strange, everyone be careful." ”

The Ninth Master also noticed something unusual, and immediately leaned against the stone wall, and whispered, "Take out the black donkey's hooves and black dog blood." ”

The person next to Xiao Ding put down the bag on his back, put the bag on the ground, and took out four black donkey hooves and a bag of black dog blood from the bag.

"Ah...... Yes...... Ah......h

Where the black dog's blood went, there were bursts of white smoke, and bursts of screams came out of the white smoke, and when the ninth master saw this, he shouted loudly: "Everyone run back, there are unclean things here, ...... quickly"

Before the words were finished, the four of them pulled their legs and ran back.

At the same time, the strange eyes stopped at the crossroads, seemingly hesitant, not knowing which way to go.

In less than half a minute, the eyes no longer hesitated, and continued to walk forward, only two steps later, and a scattered flashlight light shot from the tomb on the right.

The eyes immediately stopped moving forward, and stood in place, as if a little happy, a little excited, only to see the four flashlights getting closer and closer, and in a blink of an eye they came to the crossroads, and before the person with the flashlight stopped, the eyes pounced.
