Episode 12 recap: Song Shi Jie took on a new case again.

Song Shi Jie was curious why Xue Li, who was so beautiful, was selling goods at a roadside stall. Xue Li sadly told Song Shi Jie that it was because of the Wang family. Without hesitation, Song Shi Jie thought it had something to do with that jerk, Wang Hao Xin. Ling Long saw Xue Li slap Song Shi Jie and felt a sense of satisfaction.

To save face, Song Shi Jie approached an older lady on the street to inquire about the situation. The lady believed that Wang Hao Xin was stingy and mean, and even a murderer. Ling Long felt that the matter was complicated and didn't want Song Shi Jie to get involved. However, Song Shi Jie ignored Ling Long's wishes and decided to continue investigating the case.

Both Song Shi Jie and Song A Jiu were furious that Wang Hao Xin turned out to be such a ruthless person. While searching for clues in the surroundings, Song A Jiu accidentally stepped on bird droppings. Angered, Song A Jiu struck the bird down, and to their surprise, Song Shi Jie discovered a letter on the bird.

From the documents at the department, Song Shi Jie found a connection between Wang Hao Xin and Tan Zheng Tang. Song Shi Jie analyzed the findings to Ling Long and explained that Tan Zheng Tang and Wang Hao Xin had never met in person, only communicating through letters. Furthermore, if they were discovered, the letters would have been burned, leaving no evidence. Therefore, it would be difficult to solve the case.

Ling Long thought this was just right and a good opportunity to put an end to Song Shi Jie's investigation. Xue Li came to see Song Shi Jie and gave him a doll as a gift. Ling Long acted as a messenger between the two. Xue Li wanted Song Shi Jie to help her in a lawsuit so she wouldn't have to continue selling goods to make a living.

Song Shi Jie believed that he had to show off his abilities in the face of beauty and immediately agreed to take on Xue Li's case, which made Ling Long very angry. The next morning, after Ling Long left, Song Shi Jie let Xue Li into his home. Ling Long had mixed up the breakfast order, so she sent Xiao Feng back to clarify.

When Xiao Feng returned, he saw the ambiguous situation between Song Shi Jie and Xue Li and immediately went to find Miss Ling. At first, Ling Long didn't believe it, but when she ran back home, she saw Song Shi Jie holding a woman's head and thought he was about to be hit. However, upon closer inspection, she realized it was Song A Jiu.

Song Shi Jie wanted to fully immerse the four of them in their roles before tricking Wang Hao Xin and his group. With his disguise attracting a crowd, no one paid attention to Song Shi Jie, so he went to Xue Li's shop, pretending and acting in order to deceive Wang Hao Xin and his associates.

Wang Hao Xin observed everything from above and had his men follow Song Shi Jie to find out the truth. Song Shi Jie pretended to discover something rare and wanted the person tailing him to see it. Wang Hao Xin saw that it was a gold dust mine and saw it as an opportunity to make a huge profit.

The two of them personally visited Song Shi Jie's house. At that moment, Song Shi Jie had just returned home, feeling exhausted, but his efforts were not in vain. When he heard someone knocking on the door, thinking it was Xie Jie, he was captured by Wang Hao Xin's men. Song Shi Jie pretended to be acquainted with Tan Zheng Tang to deceive Wang Hao Xin.

Wang Hao Xin arranged for many beautiful women to bathe Song Shi Jie. Song Shi Jie was overjoyed and felt like he was in Turkey. Suddenly, something felt off. He turned his head and discovered that Ling Long had knocked out the two beautiful women and was massaging him.

In this way, Song Shi Jie successfully gained Wang Hao Xin's trust. Wang Hao Xin even brought a lot of gold as a bribe for Song Shi Jie. After considering it, Song Shi Jie pretended to hesitate but ultimately accepted the bribe.

As soon as he arrived home, Song Shi Jie quickly sent a message using a carrier pigeon. Unexpectedly, Wang Hao Xin intercepted the pigeon. At first, Song Shi Jie was confused, but when he realized that Wang Hao Xin and his group thought they were being tested, he decided to play along.

Wang Hao Xin gave Song Shi Jie a lot of silver coins to try to make him lean towards his side. Meanwhile, Ling Long rushed to Tan Zheng Tang with the first letter, intending to sow discord between Wang Hao Xin and Tan Zheng Tang, causing internal conflicts. After receiving the letter, Tan Zheng Tang became sensitive and worried, considering the possibility of Wang Hao Xin betraying him.
