Luo Zheng was not afraid of encountering any powerful enemy on the battlefield, but this kind of invisible and intangible enemy is even more difficult to deal with. There is no way to deal with it. He could only place his hope on Cao Xi. He couldn't help but ask in a deep voice: "If this is true, then this trapping formation is too terrible. If you don't use a single shot and a knife, how many of them are trapped in it and cannot get out. It seems simple, but it is extremely powerful. The wisdom of the ancients should not be underestimated. Is there a way to crack it?"

"Yes, but it takes time, it's easy to find the rules." Cao Xi said in contemplation.

"Okay, we all follow your arrangements. Take your time, don't be anxious." Luo Zheng said in surprise.

"Yes." Cao Xi agreed and hurriedly walked towards the edge of the passage. Luo Zheng followed closely to ensure Cao Xi's safety. Shi Qian was worried and followed.

The three of them entered the passage and soon came to a soldier. They saw the fork at the right side of the fork, and the deep in front of them, and the strong light was not far away. There was no end. Cao Xi marked the paper and quickly returned on the same road, drilled into the next passage, walked to the warrior, looked at the passage, calculated the distance, and made another mark on the paper.

After repeating this, leaving a passage for all, Cao Xi made many marks on his paper and immediately said in a deep voice through the headset: "Enter the passage, remember, don't untie the rope, so as not to come back. Please pay attention, from left to right, number one to six, after discovering the fork, immediately calculate the distance of walking and the direction of the fork, and quickly tell me that after the rope is used up, stop moving forward regardless of whether there is a fork. Be careful and safe, understand?"

"I understand!" The six soldiers in the passage replied immediately, walking forward, with the gun forward, and the rope tied around their waists, walking very carefully.

After waiting for a few minutes, someone shouted: "Report, I am No. 2. I came in from the previous location and found the fork for fifteen meters. Go left. Please indicate to find the danger."

"Stay on time." Cao Xi immediately found the second line and drew a horizontal line at the fork mark, indicating the distance and direction of the new fork.

Soon, the other five people also sent messages, and found the forks at different distances, and the direction of the forks was different. Cao Xi noted in detail that considering that there were not enough ropes, the people outside walked into the passage for a distance, stopped at the first fork, and then asked the people inside to continue walking forward, not to go to the forks, and immediately repay them again after discovering a new fork.

Time was slowly lost, and the signs on the paper became more and more. About ten minutes later, Cao Xi asked everyone to return, walk the second fork, and then continue to report the distance and direction found at the new fork. After finding the new fork, he immediately retreated and walked to the third fork to continue exploring the way. This was repeated.

Before time knew it, half an hour passed. Cao Xi immediately asked everyone to stop moving forward, alert him, took out a piece of paper again, and used a pen to draw the proven drawings in proportion. With the scale, the drawings looked different. Luo Zheng looked at the drawings seriously and found that they were very irregular and could not understand them at all.

After a while, Cao Xi drew all the drawings and observed them carefully. His face was extremely solemn. After a while, Cao Xi said in a deep voice: "This is not only a trapping array, but also a unique tomb Feng Shui Bureau. The jargon is called the Sun Bureau and the scientists call the Sun Tomb. What we have discovered is only the tip of the iceberg. Judging from the channel layout, the very gentle and proven rules of the Sun Tomb."

"We can understand what we say." The ghost hand leaned over and said curiously.

"The sun tombs that have been discovered have thirty-three straight passages in the northwest desert area, converging to the center, the center is round, just like the sun, and the thirty-three channels are like thirty-three golden lights dispersed. The thirty-three meanings are thirty-three heavens, all covered by the sun, and there are nine ring channels, nine are extreme numbers, which means many meanings and are also yang numbers, so they are called the Sun Bureau. Of course, this is just the definition of later generations, and only the ancients know what it is." Cao Xi explained with a solemn expression.

"There are thousands of golden lights emitted by the sun? Then we can find the location of the sun along one road? This so-called location of the sun should be the core area." Luo Zheng asked curiously.

"It is the case in theory, but the channel is tilted and has forked entries. It is impossible to tell which line is a straight line or which line is a fork. Moreover, the more you go inside, it is probably weird. Lack of oxygen can make people lose their normal calmness and rationality. If there are psychedelic things, they can make people lose their judgment and don't know if they go astray. This is terrible." Cao Xi reminded.

"You can only use ropes, connect them all." Luo Zheng suggested.

"This is a solution. Maybe they have discovered this secret and walked in with this method. No wonder they only chose one channel to enter. They saw through this dilemma without testing. There are experts among them. I suggest following the passage they walked through." Cao Xi suggested.

Luo Zheng thought about it and found that the local agencies that the tomb robbers had walked through would definitely be gone, and they would be cracked. As long as they were careful of their redeployment and trapped in, it would be the same as they walked. Then he nodded and agreed: "Brothers, go back the same way, move quickly."

"Yes!" the person who entered responded in a deep voice.

Luo Zheng keenly discovered that only six people answered, and the other six people had no voices and were not shocked. He asked, "Hurry up, drag the person inside out, what happened?"

"Ah? I understand." The six people behind agreed in a deep voice, dragging the ropes one after another.

Soon, someone shouted through the headset: "Report, dragged out, but was unconscious."

Soon, more people reported through the headset. The people were fine, but they were all in a coma. Luo Zheng was shocked and asked everyone to bring the people out. While looking at Cao Xi, he asked, "What's going on?"

"The air becomes worse the more you go inside, and there may be poisonous gas that causes people to fall into a coma." Cao Xi said in a deep voice.

Soon, the people in the passage rushed out with their unconscious brothers in their arms. Each of them looked unhappy. Cao Xi and Luo Zheng quickly signaled everyone to put the person flat in the open area and checked carefully. Cao Xi said in a deep voice: "It turns out that he was poisoned, but fortunately he was not deeply poisoned, Shi Qian?" He said, and got up and moved away from his position.

"Let me see." Shi Qian squeezed forward and checked. Seeing Luo Zheng looking at him with a serious face, he quickly said, "Fortunately, the rescue was timely. I breathed some unclean air and caused the brain to hibernate. It was not a big problem. It would be troublesome if I could take it longer. I have an antidote here, one pill for each person, and I will take it with water. I will be fine after a few minutes of rest."

"That's good, it's really dangerous here." Luo Zheng secretly breathed a sigh of relief, looked at the passage and pondered. The majestic and fierce iron-blooded warriors on the battlefield were hit, but they were hit without any strength. And they didn't know if they were hit. It was so terrible, what should I do? r1148
