What does the ending of the Hong Kong drama The Apostles 2 mean?

Let's look at the ending story first. The dust settled and Qin Huanxi came to the door of the police station. He remembered that he had promised Zhuo Kai that once Wei Dexin was killed, he would surrender himself to the police station, but at the moment he opened the door, he hesitated. He drew back his hand and asked Guess Finger to go to Thailand with him.

Zheng and Xu admitted their mistakes to Zhuo Kai, who severely criticized them, but Zhuo Kai was glad to see them safe and sound. Soon Xiao Pi, Entertainment City and Bird Shit went to the police station to find Zhuo Kai, and they said they hoped to apply for being a policeman again. Zhuo Kai accepted them cheerfully.

At this time, a gloomy man was loading ammunition into a heavy machine gun. He swore in his heart that he must avenge his good brother Wei Dexin. At this time in Thailand, Le Shao Feng thanked Qin Huanxi for saving his life, and he will be dead set on Qin Huanxi in the future. Qin Huanxi patted Le Shao Feng on the shoulder and said confidently that they would start again in the future, doing all the drug business shipped to Hong Kong in Thailand, and then calling back to Hong Kong from Thailand. Think of the bright future and give a domineering long smile with joy. .......
