Zanghai and his senior brother Guanfeng recognized each other. After reminiscing about the past, they remembered the person who wrote the intimidation letter. Zanghai suspected that the person brought back from Dongxia by his father Kuai Duo. Guanfeng remembered that Kuai Duo came back from the southwest. Zanghai analyzed that his father hid the treasure in Liu Xian's tomb.
Watching the wind, Shu Lei and Zanghai rushed to Liu Xian's tomb overnight. Zanghai remembered that Kuai Duo had taken him into the thief cave when he was a child. Kuai Duo was worried that the tomb robbers would go in to steal the burial objects, so he sent someone to seal the thief cave before leaving.Hunting the sea, watching the wind and picking thunder separately, Hunting the sea quickly found the thief hole blocked by fallen leaves, and the three of them went down into the hole together.Zanghai remembers that it was a cemetery where a couple was buried together. The coffin was extremely exquisitely made, but there was no inscription. Zanghai speculated that the inscription was hidden under the turtle next to the coffin. He opened the turtle shell and saw that it was engraved inside. Through the inscription, he realized that it was Liu Xian’s tomb.
Zanghai, Guanfeng and Shilei walked around the tomb and found that all the burial objects were stolen by tomb robbers. They either died in the mechanism or died in internal strife. The three of them searched separately, but they did not find anything valuable. Zanghai was about to leave, but suddenly found a pattern in the coffin was reversed. He gently pressed the back stone, and the wall suddenly fell off large areas, revealing a large stone inscription inside, telling the story of Shan Yizi, the honest official who cares about the people. Shan Yizi is Liu Xian's master. Zanghai picked up a carving knife on the ground, and recognized it at a glance that it was used by his father Kuai Duo during his lifetime. Guanfeng also confirmed that it was his master, but he didn't understand that the inscription was missing at the end.
Zanghai found the word “heng ” from the words scattered all over the ground. He put it in the last vacancy and activated the underground mechanism. There was a stone box hidden inside. Zanghai opened the box with his hands and feet. It contained the bronze box made by his father Kuai Duo during his lifetime. This box was a very powerful weapon. Kuai Duo was worried that someone would use this to harm the people, so he hid the bronze box in Liu Xian's tomb. Zanghai believed that his father Kuai Duo did not hide the treasures that Dongxia had brought back in Liu Xian's tomb. He put the bronze box in his arms, and then came out from the thief hole with Guanfeng and picking thunder.
Guanfeng wanted to help Zanghai kill Zhuang Luyin to avenge Kuai Duo, but Zanghai did not want to implicate him, so he asked him and thunder to seal the thief hole.Zanghai returned to Pingjin Hou Mansion alone and sent a letter to Gao Ming along the way.When Zanghai returned to the mansion, he saw Zhuang Shan directing the maid and servants to prepare for the rituals. Zanghai returned to the room and put the bronze box in the mechanism. He wanted to kill Zhuang Luyin during the rituals.
Zhuang Luyin took his family to the ancestral hall to burn incense for his dead father, but Zhuang Zhishi did not want to wait any longer. Zhuang Luyin wanted to continue the sacrificial ceremony. Zanghai hurriedly stopped him and asked him to wait for Zhuang Zhishi to come back before he talked about it. Zhuang Luyin immediately became suspicious. Zhuang Shan stood up and explained that Zanghai specially prepared the incense with golden silk. He changed it in advance. Zanghai explained that the addition of golden silk was to represent Zhuang Luyin's golden swords and iron horses for half his life, hoping that his ancestors would eliminate disasters for him and stay in the gate. Zhuang Luyin didn't believe it at all, so he asked Zhuang Shan to carefully inspect the incense burner. Zang Hai was so nervous that he sweated on his head. Zhuang Shan did not find any abnormalities in the incense burner. Zhuang Luyin refused to pursue it, and also accused Zhuang Shan of misunderstanding Zang Hai's kindness.
Zanghai was puzzled. He clearly put the machine box into the incense burner, but it disappeared in an hour. Zanghai learned from the maid that the incense ash in the ancestral hall had been taken away. He immediately went to chase the garbage truck. The masked man stopped him, and the machine box buried in the incense burner was still in his hand. The masked man complained that Zanghai was too reckless in doing things. Zhuang Luyin deliberately asked Zanghai to prepare for sacrifices, just to test him, and Zanghai suddenly realized.
Zanghai went to Zanghai overnight to admit his mistake, admitting that someone had sent poison to poison Zhuang Luyin to death within three days. Zanghai wanted to investigate the details of this person in private, but found nothing. Zhuang Luyin not only did not pursue the matter, but also comforted Zanghai. He claimed that he had too many enemies and wanted him to die. Zhuang Luyin asked Zanghai to go back and rest, and he would investigate this person by himself.
The masked man revealed that there were three enemies in the sea. In addition to Zhuang Luyin, there was also the eunuch Cao Jingxian and another person. The man was too hidden and had never been found. The three of them wanted to snatch the treasure that Kuai Duo brought back from Dongxia.Zanghai remembered that there was a copper fish in the secret room of the Hou Mansion. He guessed that the two copper fish were taken away by Cao Jingxian and another enemy. The masked man reminded Zanghai to lie down and wait until the time is right to catch all the three enemies.Zanghai originally wanted to kill Zhuang Luyin to avenge his parents and sister, but he didn't expect that there were two more enemies. He weighed the pros and cons, so he could only temporarily endure it. He hid the machine box behind the plaque in the room.
