Episode 10 recap: Chang Dong and others enter within the pass.

Ye Liu Xi asked Chang Dong what the "Si Ma Dao" is. Chang Dong explained that it is the burial place for the emperor and empress, and there is a Si Ma Dao as soon as you enter. Ye Liu Xi wondered if, in that case, Yumen Pass might be a huge tomb. Chang Dong also found it strange and didn't know when they had entered another world.

Once they arrived at the location, Chang Dong and the others stopped to rest. Ding Liu asked them what their plan was, and Chang Dong replied that they would first find the previous coffin and retrieve Hui Ba's body. Ding Liu sat in the desert, and Gao Shen brought food and drinks for him, standing nearby to shield him from the sun.

Ye Liu Xi watched Chang Dong carving shadow puppets and asked why the string on his hand was worn across the chest, while her own string was worn around the neck. Chang Dong explained that the one on his hand represents the female role, and it looks better when the character stands upright with the chest out. The one on Ye Liu Xi's hand represents the male role, and it looks better when the character looks up. Ye Liu Xi jokingly said that they were perverts who wanted to see women's chests.

Ye Liu Xi glanced over at Ding Liu and remarked that even in this situation, Ding Liu didn't dare to come over to their side. Ye Liu Xi offered to move and make space for her. As soon as Ye Liu Xi left, Ding Liu approached and expressed her thirst. However, Chang Dong completely ignored her and just pointed to the location of the water jug. Ding Liu had to go and pour it herself.

Chang Dong wanted Ye Liu Xi's help to bring down Ding Liu and the others. Ding Liu was concerned about explaining the situation to Liu Qi, as he had given them money and they would collapse as soon as they entered. Ye Liu Xi believed that Ding Liu and the others should handle their own departure. If they were scared away, that would be even better. If they were capable and not easily scared, then they would have gained two more helpers.

Chang Dong, accompanied by Ding Liu, found Hui Ba's body. Ding Liu made a phone call to Liu Qi's side and called for people to come and transport the three bodies back. Ding Liu also wanted to follow Chang Dong and his team. Chang Dong suggested driving his own car in and having Ding Liu and the others bring everything over. Ding Liu agreed.

Chang Dong found the location and drove the car to crash into it, knocking the coffin out. Fei Tang took a look at the painting on the coffin and said that it depicted a general who was melancholic after his wife's death. So, they had a sorcerer perform a ritual in an attempt to see the deceased wife. Legend has it that in ancient times, there were demonic and evil beasts in the wilderness, and there was a peculiar space where a sorcerer learned how to control these beasts. After the general's failed attempt to summon his deceased wife, he blamed the sorcerer and imprisoned him along with the beasts in that peculiar space, sealing off the entrance. Fei Tang saw a few more words on the coffin, but didn't recognize some of them.

Ye Liu Xi and the others opened the coffin, and inside was a shadow puppet dressed in Ming Dynasty attire. Chang Dong believed that such puppets existed in various dynasties, and there was a road within the borders that belonged to the inner region. Nowadays, technology has advanced outside, but the inner region still uses cameras from the previous century, indicating a possible scarcity of resources within the inner region.

Ye Liu Xi and Chang Dong saw a ray of light, similar to what they had seen on the tent before. They chased after it and discovered that the light had entered a yardang. Ye Liu Xi and Chang Dong felt that this place was likely the entrance and left a mark there. Ye Liu Xi asked Chang Dong if they should go in. Ye Liu Xi was definitely an insider, but Chang Dong hesitated. Chang Dong said that he would go in if he had promised to do so.

Fei Tang asked someone for clarification and learned the meaning of the previous words: "Flowing westward, bones yearning eastward." He thought that Ye Liu Xi and Chang Dong might correspond to west and east, respectively. Ye Liu Xi asked if Ding Liu and the others should come along, and Chang Dong thought it would be better to bring them in.

Chang Dong led the group to the exterior of the yardang, where a strong sandstorm was gathering. Normally, the yardang would block the wind, but the wind was still blowing through without hindrance. Ye Liu Xi drove the car and directly rammed into the yardang, scaring Ding Liu and the others. However, instead of being thrown out, Ye Liu Xi and the group entered a peculiar space. It turned out to be the entrance to the inner region, just as they suspected.
