When Zhang Yan and his party arrived in Guiyang, it was already the morning of the third day. Here, as they expected, it has not yet been controlled by that unknown force, and everything is normal. At this time, they were standing at the gate of Zhang Yan's house, Zhang Yan stretched out his right hand and rang the doorbell.

"Tell me...... Tell ......"

About half a minute later, the door opened, and a person met Zhang Yan's eyes. He stood and rubbed his eyes, and said in disbelief: "Dad? ”

It was Zhang Zhen who opened the door, he looked at the four people outside the door, he was also a little surprised, and blurted out: "Yan'er! You're back! Let's talk about what comes in! ”

Zhang Yan couldn't hide his joy, his eyes were filled with tears, he nodded, and then the four of them walked in. Zhang Zhen closed the door casually, there was no one else in the living room, Zhang Yan and they sat on the sofa. Zhang Zhen walked over, looked at Zhang Yan and said, "Yan'er! You don't introduce your friends either! ”

After Zhang Yan pointed to them and introduced them, Zhang Zhen also sat down and said, "Yan'er! Where did you go before? How did you come to Guiyang? ”

Zhang Yan looked at Zhang Zhen and told Zhang Zhen how they entered the prosperous era of the Tang Dynasty and how they came out of it. Then he also said his analysis, and after listening to it, Zhang Zhen said: "I see! Now I don't know how long Guiyang can stay! ”

Su Xiao suddenly asked, "Uncle! Have you ever been to Hangzhou? Did the people of the Su family also disappear? ”

Zhang Xin turned his head to look at her and said, "It's not gone!" They are also in Guiyang! ”

Su Xiao was overjoyed and continued to ask, "Are they also there, uncle?" And is Uncle Xu also there? ”

Zhang Zhen nodded and said, "It's all here, the people in the Su family's compound have moved here!" ”

Zhang Yan's mind appeared with the figures of Zhang Ju, Su Ce and Xu Yuling, and he opened his mouth to ask, "Dad!" Brother Ju, they are also in Guiyang? ”

Zhang Xin shook his head and said, "No, they are in Kangding now!" ”

Zhang Yan and Zhang Jue both had puzzled expressions, and said in unison: "Kangding? ”

Zhang Zhen nodded: "Yes!" I don't know how they are in Kangding? ”

In the belly of the mountain north of Muya, Zhang Ju and the three of them were disrupted by this sudden change. When they couldn't get back to their original starting point, they simply walked along the graveyard in front of them. They walked like this for seven or eight hours, not finding the exit, and not finding the burial chamber.

At this time, the three of them were sitting in front of an intersection, Zhang Ju's brows were tightly locked, Xu Yuling had a sad face, Su Ce had a sad face, his eyes stared at Zhang Ju and said, "Brother Ju!" Why don't we split up? Three people can choose at least three directions! ”

Zhang Ju immediately retorted: "No! It's so weird here, we can't be separated, and if someone gets lost, they can't find it. ”

Xu Yuling opened her mouth and said: "Zhang Ju is right, we have spent a lot of time, and it is estimated that it is dawn outside at this time!" ”

"Time is really waiting for no one, we are currently trapped in the belly of the mountain, I really don't know what to do?" Su Ce was a little discouraged.

Zhang Ju's head was running rapidly, and suddenly a solution appeared in his mind. He said: "Let's make a mark, we can't act recklessly, every time we come to an intersection, mark a number, and keep increasing it." We'll be able to figure out how this works if we speed it up. ”

After thinking for a few seconds, Su Ce nodded and said: "This method is feasible, the tomb path here cannot be infinite, even if Li Zhongge establishes a country here, it is impossible to dig a large area of the cemetery in three or five years, not to mention that it is still in the rock." ”

Zhang Ju nodded, and then said, "Let's start at this crossroads!" We have engraved numbers on both sides of each graveyard! ”

As soon as the words fell, the three of them began to act, and in less than a minute, a palm-sized number "1" was engraved on all eight walls. Xu Yuling asked, "Then which direction are we going?" ”

Zhang Ju replied without thinking: "Just keep moving forward!" ”

Then the three of them began to run forward, carving a number into the eight walls of each of the four intersections they encountered. They went on like this for more than an hour, when another intersection appeared before them, and they went to the wall to carve the words as before.

Su Ce suddenly spoke: "Brother Ju! The walls are notched with a 1! ”

After Zhang Ju heard this, he immediately looked at the wall in front of him, and a "1" was faintly visible on it, he thought he was dazzled, and immediately touched it with his hands a few times, and it was determined that it was "1". He asked, "We came back in a circle, how much did we carve at the last crossing?" ”

Xu Yuling immediately replied: "81! ”

Su Ce sighed and said uneasily: "Before you know it, we have passed through eighty-one intersections. ”

Zhang Ju touched the nick on the wall with his right hand, and his lips moved slightly: "We have been walking in one direction, and there is no turning in the middle, how can it be possible to turn around?" ”

Su Ce opened his mouth and said, "Yes! But there is one case where we can go back to where we are! ”

Xu Yuling blurted out, "What's the situation?" ”

Su Ce replied, "If this tomb is in motion, it is possible!" ”

Zhang Ju heard his words, thought in his mind for a few seconds and said, "What do you mean, the tomb in here has been moving?" ”

Su Ce continued: "Not bad! If the graveyard has been immobile, we will not be able to go back to where we were. Unless there is some force in it that can make us hallucinate, or subconsciously make us change direction without knowing it! ”

Zhang Ju looked puzzled and said, "But how do we have to exercise to get back to the same place?" In our minds, we keep moving forward! ”

Su Ce analyzed: "What if the tomb itself moves along some kind of circular trajectory? ”

Xu Yuling said: "Aren't we in a state of virtualization? If the tomb was turning, the walls would have passed through our bodies. ”

Su Ce shook his head and said, "No, we are a whole with the tomb, it is rotating, and the force between us and it belongs to the internal force." We will also have the same rotational speed, just like we would in a car. If you don't look out the window, you feel like you're not moving. ”

Xu Yuling was still a little puzzled: "But we walked for a few hours, to say the least, there are nearly dozens of kilometers, so long, I really can't think of how to turn to complete such a situation." ”

Su Ce continued: "I think so, if each intersection is a separate part, they turn in different directions on their own. ”

Zhang Ju seemed to have something in his mind, but he was not sure, and said, "Then what?" ”

Su Ce said: "We might as well assume that the direction in front of us is north, left west and right east, and the rear is south. Let's say we're heading north now, and the next intersection is turning clockwise. At this point, the north side of this intersection is bordered by the south side of the next crossing. By the time we get to the intersection where the two intersections meet, it may be bordered by the north and the west. ”

Su Ce swallowed his saliva and continued: "Then when we came to the next crossroads, we did not enter from the south, but from the west, and when we went out, it became the east, and we turned around invisibly. ”

After hearing this, Zhang Ju exclaimed: "This makes sense, if we are fast enough, will we encounter a situation where the two channels do not coincide?" ”

Su Ce nodded and said, "It's possible, if this situation occurs, then it proves that my analysis is correct." ”

Zhang Ju made a decision in his heart, turned to the two of them and said, "Then let's increase our speed, and stop wherever we encounter a wall." ”

Su Ce and Xu Yuling said at the same time: "Okay! ”

Zhang Ju pointed to the direction he was in and said, "Then let's start from this direction!" ”

As soon as the words fell, the three of them started running, five or six times faster than before, and disappeared in place at once. At such a speed, after passing through seven or eight intersections, they encountered a wall in the middle of the two intersections, which confirmed Su Ce's analysis, only to see that the wall at the entrance of the tomb was slowly moving to the right, and if they didn't look carefully, they couldn't see it at all.

Zhang Ju looked at the wall in front of him and blurted out: "If this is the case, this design is too clever, it can really confuse many tomb robbers, and the tomb road seems to be moving counterclockwise." ”

Su Ce opened his mouth and said, "Yes! It seems that the tombs after the Sui and Tang dynasties put a lot of effort into the design of the organs outside the tombs. ”

Xu Yuling looked puzzled and said, "Although we know how the mechanism works, how do we go down?" ”

Zhang Ju turned his head to look at Xu Yuling and said, "Don't worry, wait for it to stop." ”

The surroundings fell silent for a while, the stone wall was still moving, and Zhang Ju suddenly said, "Have you noticed it?" It was moving, but it didn't make a sound, and it didn't seem to be moving on our side. ”

Su Ce spoke: "Maybe it's also moving, but we can't tell it." ”

The wall moved for nearly a minute, and finally stopped, as if the wall had suddenly disappeared, and the whole passage suddenly opened up. Su Ce took a step forward, and Zhang Ju grabbed him and said, "Don't worry! We're looking to see what the next exercise is. ”

After hearing this, Su Ce took back his right foot that had stepped out. The three of them stared at the passage in front of them, and after a while, the tomb began to move again, only to see that the hole in front of them was gradually blocked. Zhang Ju blurted out: "I roughly counted it, plus the time we talked before, it was about a minute." ”

Su Ce asked, "Are we going to wait?" ”

Zhang Ju immediately said: "Wait! I'm going to wait for all four exits to go through it and see what the pattern is! ”

They stood in place and continued to wait, and after a while, the stone wall blocking the entrance to the cave disappeared again, and Zhang Ju opened his mouth and said, "It took about three minutes this time, let's see when it moves again." ”

Xu Yuling and Su Ce nodded one after another, time passed minute by minute, and in a blink of an eye, the tomb began to move again, Su Ce looked at the moving stone wall and said, "It's also three minutes!" ”

Zhang Ju nodded slightly and said, "It's really three minutes, it seems that the time of movement is the same as the time of staying." ”

They continued to read the seconds silently in their minds, and the time continued to pass, waiting for the most painful, but no matter how painful it was, it would pass. After a while, the two tombs were linked again, and before Zhang Ju and Su Ce could speak, Xu Yuling opened her mouth and said, "This time it took a long time, it took nine minutes, three times as long as before." ”

Zhang Ju thought for a while and said, "Could it be that the latter time is three times as many as the previous one?" Next time it's estimated to be twenty-seven minutes! ”

Su Ce said: "It's very likely, just wait and see!" ”

Nine minutes later, the tomb did move, and as they had judged, the time spent on it was the same as the time it was moving. In the blink of an eye, the tomb stopped moving again, and the three of them said in unison: "Seven minutes!" ”

Zhang Ju continued: "It's not twenty-seven minutes, which is a bit puzzling! ”

Su Ce said: "From this, we can at least determine some rules, the four directions used different times, respectively one minute, three minutes, nine minutes, and seven minutes, what does this mean?" ”

Xu Yuling said, "Why don't we wait a little longer?" See if it's the same every time! ”

Zhang Ju said: "Yuling is right, let's confirm it again, and then study what these times represent." ”

They continued what they had done before, until after the tomb road had turned around again, Su Ce said, "It seems that every cycle is the same, that is, these few times. ”

Zhang Ju frowned, touched his chin with his right hand, and said, "These few times may not be meaningful, but the numbers in them are meaningful." ”

Su Ce asked, "What do you mean by the four numbers one, three, nine, and seven?" ”

Zhang Ju nodded and said: "Think about it, this is a crossroads, just four directions, do these four numbers represent the four directions?" ”

Zhang Ju woke up the dreamer with a word, and Su Ce immediately said: "Very likely!" If we can figure out what direction each number represents, we might be able to move in a certain direction. ”

Zhang Ju kept repeating the numbers one, three, nine, and seven in his mind, and at the same time thought about Li Zhongge's deeds, but after a while, he still had no clue. Suddenly, a flash of inspiration occurred in his mind, and he said: "Actually, we don't need to care what these numbers represent, we just need to enter from the same number, and we can ensure that we move in one direction, even if the first one is wrong, we only need to try a few more times." ”

Su Ce turned his head to look at Zhang Ju and said with praise: "Brother Ju! That's a good idea, so which number do we start with? ”

Xu Yuling spoke: "From the perspective of Feng Shui, seven and nine are often mentioned, and I think we should give priority to these two numbers. ”

Zhang Ju hesitated for a few seconds and then said, "We will return to the same place after we mark eighty-one, ninety-nine eighty-one, let's start from nine!" ”

After hearing this, Xu Yuling and Su Ce also felt that there was a certain amount of truth, and the three of them stood in place and continued to wait. Time flew by, and the direction in which they had stayed for nine minutes finally arrived, and the three of them walked through. Zhang Ju suddenly spoke: "Where do we stop appropriately?" ”

Su Ce replied: "More than a hundred meters, I have calculated, the distance between the two intersections is no more than two hundred and thirty meters, but it will not be less than two hundred and twenty meters. ”

Zhang Ju's lips moved slightly: "In this way, it is estimated that at two hundred and twenty-five meters, a normal person walks about one meter and twenty-five meters per second, which is just three minutes." It takes 40 minutes to make a second turn. Basically, people who come in rarely stay in the cemetery, and in this way, they can keep the cemetery open all the time. ”

Su Ce said: "Then let's go to a place of about one hundred and twelve meters!" ”

Time continued to pass, and they came to the middle of the two crossroads and waited. It wasn't until the intersection came in the nine minutes that they crossed the graveyard. In this way, they walked all the way forward, and after passing through more than thirty intersections, a stone gate appeared in front of them.

The stone door was closed, more than two meters wide and two people high. On both sides of the stone gate, there is a statue that looks like a human being. The statue was almost two people tall, and the three of them could roughly see the faces of the two statues through their red pupils. The statue had an oval face, a prominent forehead, standing eyebrows, triangular eyes, a straight nose, large nostrils, an open mouth and teeth, a somewhat short upper lip, and earlobes in both ears that were much longer than normal.

Zhang Ju opened his mouth and said: "This portrait is so strange, I have never seen it before!" ”

Su Ce said: "Yes! See you for the first time! Has Yuling seen it? ”

Xu Yuling shook her head and said, "I've never seen it before!" ”

Zhang Ju said: "Ignore them for now!" ”

After speaking, he walked to the stone door, stretched out his hands and pushed, but the stone door did not move at all. Zhang Ju opened his mouth and said: "This should be the door of the tomb, but I don't know how to open it!" ”
