"Then what are you waiting for, we'll go down now." The fat man said.

"Wait, don't rush yet." Lai Zi interrupted the fat man, and after arranging for everyone to get ready, he signaled: "Let's prepare first, after all, this is inside the Yongdao, unlike playing the Rubik's Cube, you can see the difference from the different colors outside." ”

"Yes." Several people nodded at the same time, and now they were in admiration for Lai Zi's keen observation.

"In this case, untie the rope first." Lai Zi first motioned for everyone to untie the rope, and then said: "There must be one or two people left in this main tomb, and they can't all go down, otherwise we won't know if we are passive." ”

"Damn! I don't want to stay, fat man. The fat man shook his head repeatedly.

Several people seemed to have guessed that the fat man would say this, and couldn't help but look at Zhao San.

"Third uncle, my legs and feet are not good, I will stay." Zhao San also nodded clearly in his heart: "In terms of the kung fu in my hands, except for the military brother Ye Jiu, only the third uncle and I can fight with these mausoleum guards!" Others, third uncle, I am not at ease. ”

In fact, Zhao San knows that for everyone, on the one hand, Lai Zi and Lady Na are needed to crack the Yongdao here, and on the other hand, someone needs to follow the two of them for a long time, after all, Lady Na and Lai Zi are hiding a lot of things from everyone, and Zhang Meng is weak alone, so he must take care of each other with the fat man. Qingzhi and Xiaolou disappeared, so naturally there was only himself among the remaining people.

Lai Zi seemed to have noticed it, but he didn't care, just continued: "In this way, I am in front, Fat Man and Zhang Meng are behind, and Lady Na is behind, and the four ropes of our will be buckled first, and then connected to the rope of the third uncle." ”

The four of them nodded and complied.

Then he said hello to Zhao San, and jumped over the flap.

When the light of the flashlight illuminated the corridor below, the four of them realized that the corridor behind the flap was really exactly the same as the one above, not only was it just as narrow and crowded, but even the murals on the wall were the same. This is somewhat exciting, because the closer the truth is, the more likely it is that Raiko and Lady Na have thought of the solution before.

Zhang Meng and Fat Man don't have a good solution to this kind of Rubik's Cube-like tomb network, so they can only listen to Laizi and Lady's instructions.

"The theory of the Rubik's Cube is that no matter how the road is interspersed with changes, the four points as the central axis will not move." Lai Zi explained: "The Yongdao we just came down is also the Yongdao guarded by the third uncle is one of the Yongdao, as long as we can find the central axis Yongdao that crosses with the third uncle, we can determine the two base points of the central axis, with these two Yongdao, we will restore it step by step, as long as we return to the original state, we can find Xiaolou and the pheasant......

"Isn't the tomb where we are now another central axis?" Zhang Meng asked.

"It's not." Laizi shook her head and said.

Zhang Meng and the fat man listened to a rough idea, although they were still not very clear, but they also understood that what the four of them were looking for now was a corridor that crossed the road where the third uncle was.

"How do you find that?" Zhang Meng asked.

Lai Zi looked at the fat man: "Just follow the fat man's method just now, and see where the dust fluctuates greatly." As long as there is dust fluctuation, there must be other corridors that have been moved, as long as we get to all the flips, and then look down along the corridors, we can find another central axis corridor we are looking for. ”

Zhang Meng thought for a while and said, "But in this way, we can only find other corridors, but we still can't confirm which one is the central axis corridor that can't move, right?" ”

"The greater the fluctuation of the dust, the greater the possibility of change, we just need to find all the flaps here, and then go in to see, as long as which dust fluctuates smaller, which one is what we are looking for."

Listening to Lai Zi's answer, Zhang Meng felt a little difficult: "It seems that I can only do this." ”

The fat man was a little confused when he heard it, shook his head and said: "Fat man, I'm most annoyed to play the Rubik's Cube, I am dizzy when I listen to it, don't tell us about this principle, you can understand it with the big, what do you say, I will do it with Zhang Quede." ”

"Huh." Listening to the fat man's response, Lai Zi smiled slightly: "By the way, fat man, where did you see the new Yongdao when you came down before?" ”

The fat man identified the direction, and then pointed to the back: "The position of the flap I saw just now should be in the back, what, do you want to go over and have a look?" ”

"Don't rush yet." Laizi said very steadily: "Find the other flaps first." ”

"Okay."

The four of them slowly loosened the rope around their waists, and then followed Laizi's instructions to observe the fluctuations of dust in the corridor. After a carpet search, the four of them really found a lot of traces that had been passive, and then marked them with marks, until there were no other discoveries, Lai Zi decided to let Zhang Meng and the fat man answer on it, and he went down with Lady Na.

After the division of labor was completed, they began to touch the corridors behind the flap one by one.

After all the flaps were uncovered, Zhang Meng and the fat man glanced at each other, and cautiously leaned towards the place where they could settle down.

I don't know how long it took, Zhang Meng seemed to hear the fat man's hungry stomach start to scream, so he rushed down and asked, "I said Brother Laizi, are you okay?" ”

"Flutter!"

Listening to Zhang Meng's words, the fat man almost didn't laugh out loud, and secretly said in his heart, if outsiders heard this, they would still think that Laizi had done something to Lady? Then he said, "Do you think this is really playing with the Rubik's Cube?" If you understand the principle, you can restore the original appearance. ”

"It won't take that long, will it?" Zhang Meng said in surprise.

"This is a three-dimensional intersecting corridor, and even if we find the central axis, it will take a lot of time to restore the original appearance." The fat man knocked on the flap with his hand and said, "Fortunately, these flaps are not sinking, and it doesn't take too much effort." Hey...... I don't know if these things are some kind of treasure. ”

"Just think about your baby!" Zhang Meng glanced at the fat man with contempt, but he was worried about Xiaolou's safety. Although Lai Zi knows how to restore the tomb here, it is too complicated after all, and if there is a mistake, it is likely to take a lot of time to start again, and I don't know if Xiaolou and Qingzhi can hold on to it at that time.

Just when Zhang Meng's heart was going up and down, Zhao San's voice came from above.

"Cute boy, fat man! Cute boy, fat man! ”

The voice was low and heavy, as if it was Zhao San's deliberately suppressed voice. Although Zhang Meng didn't understand, he didn't make any mistakes, but also lowered his voice and responded: "Third uncle!" ”

"Moe boy, I think there's movement up there."

"There's movement? What's moving? Zhang Meng suddenly thought of those mysterious mausoleum guards, and hurriedly asked: "Could it be that those mausoleum guards came in?" ”

"I don't know."

"Third uncle, turn off the flashlight first." Zhang Meng reminded Zhao San.

Hearing Zhang Meng's reminder, Zhao San hurriedly turned off the flashlight, and only relied on his visual eyes and hearing to distinguish the slowly approaching sound, and only said after a while: "It's not like those elusive mausoleum guards." ”

"Not a mausoleum keeper?" Zhang Meng was slightly startled and muttered in a low voice: "Could it be the two of them, Brother Jiu and Brother Jun?" ”

"It's even more impossible!" The fat man hurriedly interjected: "What strength do little ladies and military brothers have, how can they make a sound when they walk?" If they really want us to find out, they don't have to be like this, they definitely aren't our people. ”

"That ......"

Before Zhang Meng could figure out what was going on, he heard two gunshots, "bang, bang". The sudden two gunshots frightened Zhang Meng's heart, and the third uncle was in trouble now.

"Third uncle, wait for me to go up." After speaking, Zhang Meng gave the fat man a look, and hurriedly grabbed the rope that was holding Zhao San.

Hearing Zhang Meng's words, Zhao San hurriedly stopped: "Don't, don't come up!" ”

Although Zhang Meng was anxious, he heard Zhao San's tone seem to be very calm, so he lowered his voice and asked, "Third uncle, you fired the gun just now?" ”

"It's not." Zhao San replied calmly: "It's those mercenaries from Bogut, they also came in." ”

"What?" Zhang Meng was taken aback.

Along the way, everyone has seen a lot of people from Bogut Company, but most of them are cannon fodder, and there is no real living person who has gone deep into the tomb, Zhang Meng thought that they had been wiped out, but he didn't expect that some of them would come here alive.

"Yes, someone fell down just now, and they thought it was the enemy, so they fired the shot." Zhao San said and instructed: "By the way, you should be careful when looking for the tomb below, don't be hit by their black guns." ”

"Okay."

"They're coming, I can't say much, expose my location." Zhao San said.

"Okay, third uncle, take care of yourself above."

After talking to Zhao San, Zhang Meng learned about the situation of Bogut Company, and then walked a few steps quickly, lying on the Yongdao where Lai Zi and Lady Na went down, and reminded the two people below: "The people from Bogut Company have come in, and some of them have fallen into this Yongdao network." You and Lady Na are down there and watch out there, don't get caught in their guns. ”

After Zhang Meng finished speaking, he didn't hear Lai Zi and Lady's response, but Zhang Meng felt the rope on his waist tighten, and knew that Lady Na and Lai Zi had heard his words, so he didn't continue to speak.

"it!" After listening to the conversation just now, the fat man hurriedly took the M4 carbine he got from Qingzhi, carefully observed the surrounding anomalies, but muttered to Zhang Meng: "It's enough to fucking trouble to crack the Yongdao network here, now it's good!" These Bogut mercenaries have also been involved, what a fucking fuel to the fire, if this is a black shot, will we ****** still live? ”

Listening to the fat man's chatter and abuse, Zhang Meng didn't speak.
