Episode 4 recap: Shui Yao Er saved Huo Xiao Xie and obtained the Jade Embryo Pearl for the Mu family.

Huo Xiao Xie couldn't withstand the relentless attacks of the Wind Divine Hunter for long. Just as he was about to reach his limit, San Zhi Liu stepped forward to assess the situation. However, he was secretly struck by an arrow from Butler Zhou. Zheng Ze Dao and his team rushed to the mountains with an arrest warrant signed by the sheriff, charging Butler Zhou with abuse of power. Butler Zhou quickly retreated while Huo Xiao Xie took San Zhi Liu and left. Bie Hou and Lang De Ben were sent to the hospital for treatment.

San Zhi Liu was barely hanging on, and Shui Yao Er gave him a pill to take, which slightly restored his strength. He asked Huo Xiao Xie to find water while he had a private conversation with Shui Yao Er, inquiring whether the pill he took was the Shui Ning Dan (Water Condensing Pill). Shui Yao Er admitted it, indirectly confirming his identity. San Zhi Liu told Shui Yao Er that Huo Xiao Xie possessed a unique fire bloodline, and every twenty years, the Wu Xing family would recruit new members. It was imperative for Huo Xiao Xie to participate when the time came. After entrusting this information, San Zhi Liu breathed his last.

Zhang Si Ye ordered the complete eradication of the Wu Xing family. Zheng Ze Dao found Huo Xiao Xie and urged him to hide as soon as possible. Shui Yao Er accompanied him, and during their conversation, Zheng Ze Dao learned that Shui Yao Er was the daughter of the Water family, whom his father had instructed him to visit.

Huo Xiao Xie decided to bury San Zhi Liu first and then leave Feng Tian. However, on the way, he suddenly felt an extreme coldness within his body. Shui Yao Er used rope to tie off Huo Xiao Xie's blood vessels to prevent the spread of the poison gas. She then found the Yan brothers and asked for their help in hiding Huo Xiao Xie, promising to assist in finding the Jade Embryo Pearl.

Huo Xiao Xie inadvertently mentioned that Shui Yao Er's portrait was in the Linglong Mirror. Shui Yao Er had heard from a fortune teller that everyone sees their destined person in the mirror. She asked the Yan brothers to treat Huo Xiao Xie kindly, and the group continued their journey. However, Huo Xiao Xie's poison gas surged, and he fainted on the road.

Shui Yao Er asked the Yan brothers to divert Zhang Si Ye's attention while she took Huo Xiao Xie to seek help from the Mu family.

Yan Jing Tian instructed the two brothers to ride a horse together along the riverside path, occasionally switching positions to create the impression of a man and a woman riding the horse. The Wind Divine Hunter fell for the trap, chasing along the river for a long time without any success. When Gou Jian discovered the trick, he reported it to Zhang Si Ye, and the search teams disbanded.

Shui Yao Er, accompanied by Huo Xiao Xie, arrived at the post station. Lin Wan, a daughter of the Mu family, used her exceptional medical skills to extract the Jade Embryo Pearl from Huo Xiao Xie and kept it for herself, rejecting his debt of gratitude. Shui Yao Er didn't mind the Jade Embryo Pearl, expressing that saving Huo Xiao Xie was the most important. Lin Wan noticed Shui Yao Er's feelings for Huo Xiao Xie and mentioned that while extracting the Jade Embryo Pearl, she sensed a strange and malicious fire within him. This indicated that his future might be full of hardships, advising Shui Yao Er to consider it carefully.

Shui Yao Er also explained that the Jade Embryo Pearl was obtained from the Zhang family, who were currently conducting an intensive search. Carrying it with them could bring them great danger. Lin Wan quickly hid the Jade Embryo Pearl and asked Shui Yao Er to help pack their belongings. They hastily departed from the post station overnight in a carriage. After Huo Xiao Xie regained consciousness, Shui Yao Er followed Lin Wan's instructions by exposing him to the sun to resist the cold and prepared a variety of meat and vegetables to nourish his body. Shui Yao Er was skilled in cooking and was well known among the Wu Xing family.

When Yan Jing Tian arrived at the post station, Shui Yao Er was teaching Huo Xiao Xie martial arts. They didn't dare to mention that the Jade Embryo Pearl had already been taken by Lin Wan. Huo Xiao Xie insisted that in order to retrieve the Jade Embryo Pearl, he must be taught the Huo Mian Palm technique. Unable to resist their earnest pleas, Yan Jing Tian reluctantly agreed.

Just as they were about to begin their training, the two brothers from the Huo family informed Yan Jing Tian that Zhang Si Ye had arrived at the foot of the mountain and would soon surround the post station. Shui Yao Er suggested that they should take the opportunity to capture Zhang Si Ye and his men in one fell swoop.
