One night during a thunderstorm, Xu Yuan, a nurse at the Changsha Military Hospital, made a night check and found that many soldiers were arrayed in the central hall. Xu Yuan didn't know what to do and reported to the head nurse. The two saw that the soldiers' clothes were marked with the 401st unit. The head nurse explained that they were under Changsha Defense Officer Zhang Qishan and that normal treatment would be enough. When bandaging the wound, Xu Yuan only felt the cold eyes of the soldiers, which made her confused. She went to the bathroom to wash her face, and when she came out, she found that the middle hall was empty.

A few minutes later, Zhang Qishan led the troops to the hospital. Adjutant Zhang Xiaoyu informed that the officers and soldiers of the 401 unit who were ordered to repair the moat had just disappeared en masse. Zhang Qishan found that the clock on the wall had stopped for ten minutes, indicating that the incident had just happened. There were no footprints outside the hospital. The officers and soldiers could not enter from the front door. They could only have come from underground. When they asked the frightened nurse Xu Yuan, the other party could not say anything.

Zhang Qishan took Zhang Xiaoyu to find a secret passage in the hospital. When they walked into a ward, they found a hollow drum sound on the ground. Zhang Xiaoyu stepped forward and pried open the wooden board. There was a bottomless hole underneath.Zhang Qishan believed that the officers and soldiers came from here, so he ordered to throw down smoke bombs to test, and then dived into the deep space himself. He found some medicines and bandages, which were exactly the same as those seen in the atrium of the hospital. There was a wall nearby. According to common sense, the officers and soldiers were hiding behind the wall. Zhang Qishan realized that someone was deliberately guiding him to dig out the story behind it.

Several people searched near the wall and found a two-inch-square hole. Zhang Qishan threw a stone in and speculated that the wall was 400 meters deep. However, the hole was too small and could not be entered normally. Zhang Xiaoyu remembered that ancient books recorded a cave specially designed with a small diameter that could only allow children to enter and find the mechanism. Zhang Qishan immediately checked the hospital list and found that there was indeed a 5-year-old child.

The wall was indestructible. Zhang Qishan asked his adjutant to ask Master Ba to help. The two had just had an argument and were still in a cold war. Zhang Qishan reminded his adjutant to go out and look for him.The Mystic Nine 2 The Qi Family Qi Tiezui had already expected Zhang Qishan to come to the door through divination, so he hid in a coffin and prepared to sneak out of the city. Zhang Xiaoyu saw the clue when he passed by the city gate and pulled the coffin directly in front of Zhang Qishan.

Qi Tiezui still wanted to find a reason, but Zhang Qishan directly informed him of the discovery and asked Qi Tiezui to help find out the mechanism. Qi Tiezui found that the walls were covered with star patterns, the entire house belonged to Yang, and there were people living inside. If a piece of brick was removed at will, the entire wall would be destroyed.Qi Tiezui observed the entrance of the cave, but it was beyond his ability, so he suggested asking Wu Laogou, the fifth master of The Mystic Nine 2. The search and rescue dog in Wu Laogou's family was beyond ordinary people's imagination, but Zhang Qishan might not be able to ask Wu Laogou for help.Zhang Qishan remembered that the two had a deep hatred because of the shooting of Wu Laogou's housekeeper.But Qi Tiezui was afraid that Zhang Qishan would not let him go, so he took the initiative to become Zhang Qishan's lobbyist.

Zhang Qishan refused to let Qi Tiezui leave on his own, so he stuffed it into a coffin and carried it outside Wu Laogou's door. Wu Laogou learned that Qi Tiezui had come out for Zhang Qishan, and pulled out a search and rescue dog to scare him. Qi Tiezui knew that the grudge between the two people was difficult to resolve, so he explained that hundreds of lives were involved. Moreover, since Zhang Qishan became the Changsha garrison officer, he had made a lot of contributions, and it was a last resort. Wu Laogou thought for a moment and asked Qi Tiezui to tell Zhang Qishan to ask for his help personally.

Zhang Qishan researched the use of bricks and tiles for walls, and asked Zhang Xiaoyu to visit several nearby brick and tile factories. He thought that it was not possible in a noisy market and was too remote to facilitate transportation, so he finally settled on the Liuyang Brick and Tile Factory.Several people came to Liuyang Brick and Tile Factory. The factory building had long been abandoned, and there were a few golden basalt bricks scattered on the ground, which were consistent with what they saw in the secret passage.There was a wall at the end of the passage in the brick and tile factory. Zhang Xiaoyu used a tool to break it open, and saw a Tai Chi array made of corpses in front of him. Zhang Qishan looked carefully and found that the corpse was in a state of suicide.Wu Laogou took his two disciples with the rolling curtain canopy to watch a play in the opera garden. Every time they saw Sun Wukong causing trouble in Heaven, he would throw away someone.
