After exiting the secret passage, head to Dongyu Village in the east! Enter Dongyu Village, make preparations, and then get news from a young man on the second floor of the hotel (select "I don't know" in the dialogue selection). People from Tianmen seem to often go to sea from here. After that, I went to the boatman on the right side of the village and asked him about the situation. I learned that the people from Tianmen did go to sea from here to the Baigui Cave in the east. Qianyun asked the boatman to go out to sea, but was told that the boat had been chartered by a guest, who might be drinking in the tavern. Later, when I came to the tavern, I saw a panicked man. After asking, I learned that he was the person who chartered the boat. I then made a deal with him and helped him find his heirloom in exchange for the right to use the boat. After leaving the hotel, behind the house at the bottom of the village (walking down between the two houses), you will see a sneaky little thief. Defeat him and get the heirloom. Then give it to the charterer. The transaction is successful! Finally, he went to find the boatman and immediately set out to sea. 
After coming out from the shore, go east and enter the Hundred Ghost Cave, which is another maze. When you reach the end, you find that it is your younger brother Long Yue and Uncle who were caught by Tianmen. After defeating everyone in Tianmen, a mysterious person appears. It turns out that He is Fang Guhong, the hero who was as famous as Yin Yannan in the world twenty years ago. He learned from him the true purpose of Tianmen. He needed to use "Tongtian Jade" to complete the experiment of "human and devil communion". He needed to defeat him and obtain all the artifacts. These five artifacts were hidden by him and Yin Yannan in five places twenty years ago. 
rescued the uncle and his younger brother Long Yue. After parting ways in Dongyu Village, the three began to search for the last two artifacts. One of them, the "Pangu Ax", was hidden in the Purgatory by Fang Guhong. Walk north from Dongyu Village to the Purgatory, go to the end, defeat the nine-tailed fox demon, and obtain the Pangu Ax. After coming out, at the request of Jiuzhi, he came to the village where she was born, Guiyan Village. Zhizhi revealed that when she was a child, she heard rumors about "Baby" from her elders. When I came to the village chief's house on the left side of the village, I learned after talking that the village did have the "East Emperor Bell", one of the artifacts, but to get the East Emperor Bell, I also needed to get the "Tongtian Jade" and the "Night Pearl". Now that I already have the "Tongtian Jade", I just need to get the "Night Pearl". After leaving the village, walk up to the ancient imperial mausoleum. Defeat the minions of Tianmen in the deepest part (note that you have to fight the BOSS twice here) and obtain the Luminous Pearl. After that, go directly to the back mountain above Guiyan Village and investigate the stone tablet in the upper right corner. When the dialogue option appears, select: "Return of Nanyan" and enter the dark secret realm. This map has many teleport points, but it is not very difficult. Go to the deepest part and defeat Zhong Ling to obtain the last artifact "East Emperor Bell". Afterwards, he returns to Yan Village, bids farewell to the village chief and leaves the village. Knowing that something happened at Nanjian Gate, Qianyun decided to go back and have a look.
Returning to the Nanjian Gate, I found that it was covered in blood and seemed to have been massacred. When I came to the Jueqing Cliff on the left side of the Nanjian Gate, I found the dying master. After a conversation, I continued walking to the left. Finally I saw the culprit, senior brother Aoshuang, old and new grudges, let's settle them here. After being defeated, Aoshuang repented resolutely, and then brought Qianyun and the others to Tianmen. There was nothing to say. It was the last battle, so try your best! (over)
