Wu Laogou followed Hatoyama Yoshi to a remote place. Along the way, he found many Japanese mining and even saw the 401st unit, but the other party seemed to have no soul and was advancing in an array mechanically.Finally stopping in a cave, Hatoyama Yoshi told him to tame a creature. Wu Laogou only saw a ox released from the iron shed and didn't understand what was special. Then he saw a huge four-legged monster crawling out of the depths, biting the ox's neck, and eating only the bones in a few minutes.

Wu Laogou was so frightened that Hatoyama Yoshi explained that he had sacrificed more than a hundred lives to catch this thing, which showed how powerful it was. As long as Wu Laogou could tame it, he would tell him the secret of the Separation Building and let Wu Laogou go back.If he couldn't be tamed, Wu Laogou would probably die and leave alive.Zhang Qishan pushed Half Li up the mountain. After walking for a long time, he still didn't reach his destination. Zhang Qishan suspected that Half Li had lied to him. Half Li explained that he had also been a follower of the Ancestor of the Second World and had been to the Second Tower. At that time, he saw that there was a trap, so he quit early.The two continued to move forward and reached a place with heavy dew. Half Li lit dry grass to test the wind direction and found the entrance to the underground river.

Zhang Qishan looked down from the top and saw that the entrance was very narrow and the river was very fast. Based on the mountain topography, Ban Li speculated that there were stone gorges in the waterway, making it impossible to walk through. In order to know whether Hatoyama Mizhi had passed by, Ban Jie Li took out a magnet and let Zhang Qishan explore it slowly.Zhang Qishan was not proficient and relied on brute force to work. Half Li told the key points. Zhang Qishan indeed hung up a medal, which was something left by the Japanese. It was confirmed that Hatoyama Yoshi passed through the underground river. Half Li said that he would ask his subordinates to help find the exit.

Huo Xiangu went to Baihua Church to meet Ding Qiansui. Ding Qiansui received the porcelain vase and handed over all the Huo family's IOUs. The Huo family's debts were cleared, but Huo Xiangu was charged with Tongri. Huo Xiangu was curious about the function of the porcelain vase, and Ding Qiansui told him that it was used to make people experience various illusions.Someone reported that Qi Tiezui was about to be attacked, but Ding Qiansui did not avoid Huo Xiangu.

Zhang Xiaodi investigated Ding Qiansui, who entered the palace as a eunuch at a young age and befriended a Belgian missionary. Later, he acquired American citizenship through familiar relationships. A few years later, he returned to the palace and became popular. After the Qing Dynasty was overthrown, Ding Qiansui brought a large amount of gold to Changsha and settled in Changsha. In addition to dealing with the Japanese, he also helped the Americans to launder money. When he learned that someone was investigating, he immediately moved to the Baihua Church. If he wanted to touch Ding Qiansui, it might involve the diplomacy of the two countries.

Zhang Qishan asked Jie Jiu for help. Jie Jiu first asked if his views on Wu Laogou had changed. Zhang Qishan and Wu Laogou went to the underground palace and found that although Wu Laogou was uneducated, he had an innocent heart and knew right from wrong.Jie Jiu was very satisfied, explaining that Baihua Church was under the jurisdiction of the Americans, but if Ding Qiansui was infected with smallpox, the United States would definitely send him out. The corresponding Puji Hospital belonged to the Chinese Consulate, and they could take the opportunity to capture him then.

Everything went smoothly. Zhang Xiaodi found a child and put ointment on Ding Qiansui's neck. The effects of the medicine caused it to be extremely itchy and unbearable. Zhang Xiaodi took the opportunity to spread rumors that everyone was afraid of smallpox. Ding Qiansui was taken to the Changsha Police Station and imprisoned.Ding Qiansui still flaunted himself as an American citizen and refused to say anything. Zhang Qishan explained that his hometown had a secret technique that could crush the skull bit by bit and endure the excruciating pain. As he spoke, he started to attack. Ding Qiansui was really scared, so he began to tell the truth.

Hatoyama Yoshi's boss Tottori found Ding Chitose and promised generous benefits. Ding Chitose was fed up with the life of a slave and wanted to completely turn over and live the life of a master. He couldn't resist the temptation of profit. With the help of the Japanese, he bought the Taihe Building, secretly delivered supplies to Hatoyama Yoshi, and even studied the magic in the Gosei Building. Ding Chitose did not hide it, indicating that the Japanese's ultimate goal was not the Gseok Building at all, but the end of the waterway in Xiangxi.Zhang Qishan was very curious, but Ding Qiansui refused to say more. He took out a porcelain bottle and took a few pills, and then disappeared like a mutation.

Qi Tiezui sneaked into a caravan and came to Xishan Taoist Temple. While rummaging for things, he was attacked by bandits. The bandits killed the caravan. Just when Qi Tiezui was about to attack, Zhang Qishan arrived in time and subdued the bandits with a few simple moves. Zhang Xiaodi found a letter from Ding Qiansui who ordered Qi Tiezui to be killed.
