At Pingwan Business School, Cui Tiejun, Xu Guozhu and Pan Jianghai met their former colleague and comrade-in-arms Lao Jin.Lao Jin helped them in an explosion they encountered, eliminating the dangers.Zhou Mao suggested that everyone have a meal in the school cafeteria together, but Trident initially refused due to discipline reasons.However, after learning that it was just a simple meal, Cui Tiejun proposed to walk there and visit the campus by the way.However, Zhou Mao left halfway due to emergencies.

The trident was led to the canteen's private room, but found that it was full of their students.The three of them felt that the atmosphere was not right, so they hurried to the hall to make their own meals.Lao Jin wanted to dissuade them to avoid embarrassment from Zhou Mao coming back, but Cui Tiejun thought it would be better to have less than more things.After Zhou Mao came back, he showed disdain for their simple dining style, especially Mr. Kang sneered at their meals and claimed that he knew their superior, Director Guo.Mr. Kang then drove away other guests, booked the venue and ordered high-end dishes, and invited several bosses to have a meal together.Trident insists on eating simple meals and refuses to drink alcohol.Zhou Mao and President Kang were very dissatisfied with this. Lao Jin tried to help them, but President Kang was still not satisfied after drinking four pots of wine.Xu Guozhu couldn't bear it anymore, so he poured out the wine from the wine glass and left with Lao Jin who was already drunk.Lao Jin revealed that Mr. Kang’s backstage was tough and he couldn’t afford to offend him.

Lao Jin originally wanted to send the Trident home, but he gave up because the time for renting a car was up.The three of them didn't say much and took Lao Jin into the van.When Pan Jianghai went home to look for Xu Man, he found that she was with the boss just now, and the two got into the car together.Xu Man called and explained that he was close to his home, so he went back first.

Trident felt uneasy when he saw Lao Jin whispering at the wine table.Lao Jin also felt frustrated. Since resigning and going into business, he had failed repeatedly in investment. He was full of envy when he saw them.When he arrived at Lao Jin's house, he got off the car and saluted. The three of them felt mixed feelings.They understood that this dinner was obviously for them.Pan Jianghai talked about Xu Man, and the next day they found Chu Dongyang and wanted to check her information, but Chu Dongyang refused on the grounds that it was not conducive to unity.

Xu Man proposed to formally take Trident as his teacher and was willing to undergo the test, but was rejected.She said she had nothing to hide. She walked with Li Xizheng yesterday because he was his mother's friend, but Trident obviously didn't believe it, which made Xu Man very sad.

Lao Tian came to ask Trident for help, and they dug out a man named Du Chao based on the clues.But after the arrest, his villa was evacuated, and Du Chao himself was unaware of it.The property said that Du Chao called to confirm it himself, but he was in the interrogation room at the time.Lao Tian had to ask for help from the Trident again.They walked around the scene and found the key evidence, and the surveillance was found, which made Lao Tian very happy.

Xu Guozhu found out that Lao Jin had gone to Sister Hua's store and asked the technical director to install the camera.Xu Guozhu was very dissatisfied with this because Lao Jin had pursued Sister Hua.He satirized Lao Jin's drinking behavior that day, and Lao Jin hurriedly begged for mercy, not wanting to lose his dignity in front of Sister Hua.
