Episode 4 recap: He Lan Xin Yue drives Tai Chu away.

Before, Zhao Guangye had given He Lan Xin Yue the time of one incense stick to bring Tai Chu out. When the time was up, Tai Chu came out with He Lan Xin Yue, but he held an arrow against He Lan Xin Yue's neck. He Lan Xin Yue pleaded with Zhao Guangye not to harm him.Zhao Guangye didn't expect this person to truly look identical to him. Tai Chu asked if Zhao Guangye really intended to kill him. Upon hearing these words, Zhao Guangye remembered the way the fake Xin Yue had stood in front of him before, feeling that Tai Chu's tone was exactly the same as that of the fake Xin Yue. He Lan Xin Yue explained that she prophesied that this person, who looks just like Zhao Guangye, could ward off disasters for him. So Zhao Guangye took Tai Chu back.

He Lan Xin Yue was extremely anxious, believing that Tai Chu couldn't stay here. She felt that now Zhao Guangye needed Tai Chu, but if he didn't need him anymore in the future, he would surely kill him. Tai Chu insisted on staying, saying that wherever He Lan Xin Yue stayed, he would stay as well.

The princesses from the county came over to see Zhao Guangye. On the surface, they showed concern for him, but their real intention was to see if Zhao Guangye was truly injured and the extent of his injuries. The Zhao Guangye present here was actually Tai Chu, who had created two wounds on himself. Chen Yang also arrived and stated that Zhao Guangye needed rest, urging the princesses to leave quickly.

The princess of Nan Chu Kingdom wrote a letter to the princess, stating that Zhao Guangye was seriously injured and advising her to seize this opportunity to leave. Zhao Guangye remarked that he had waited for so long and finally caught the attention of the assassins. He had come here to lie in wait and had indeed captured the princess of Nan Chu Kingdom.

Zhao Guangye asked the princess of Nan Chu Kingdom to agree to open mutual trade at Hanma Port. Initially, the princess was reluctant because the location was crucial for her kingdom. However, since she was captured by Zhao Guangye, she had no choice but to agree.

The King of Bei Rong also learned about the news of the two countries opening trade. He didn't expect Zhao Guangye to take such actions right under his nose, indicating that he was ready to confront him. He instructed his subordinates not to worry about these matters for now. Currently, Zhao Guangye and Chen Yang often go out, leaving Tai Chu in the palace. He Lan Xin Yue believed that Chen Yang wanted to use Tai Chu as his shield and was worried about his safety. She urged Tai Chu to return home immediately, but Tai Chu refused and insisted on staying to accompany He Lan Xin Yue.

Zhao Guangye investigated and found some information about wooden dolls that could be similar to Tai Chu. He had someone invite Yan Shi to the palace to take a look. Tai Chu came to find Zhao Guangye and warned him that those people who seemed concerned about him were only interested in assessing the extent of his injuries. Tai Chu advised Zhao Guangye not to trust them.

He Lan Xin Yue was furious that Tai Chu had once again revealed these matters to Zhao Guangye. She believed that Tai Chu was just a wooden puppet, unaware of her thoughts and how much she worried about him. She feared that one day Zhao Guangye would kill Tai Chu. However, Tai Chu believed that Zhao Guangye would never do such a thing. He Lan Xin Yue drove Tai Chu away, considering him a burden.

In reality, He Lan Xin Yue only wanted Tai Chu to leave for his own safety, feeling guilty for causing harm to him. Meng Ji entered the palace and saw Tai Chu, and Zhao Guangye confirmed that he was his puppet. Meng Ji was surprised by how exquisitely the puppet was made, unable to tell the difference.

Tai Chu wanted to have a heart so that he could understand He Lan Xin Yue. Meng Ji used the Thousand Emotions technique to control Tai Chu, and Zhao Guangye instructed Meng Ji to give Tai Chu a heart that he could control.
