The shooting progress had exceeded one-fifth, and nothing had gone wrong so far. The film had been progressing in a steady and orderly manner.

According to the script, the part in the police dog training base had come to an end, and Lightning, played by Famous, had officially become a member of the police dog team. Led by the protagonist Lin Feng, they came to the Northwest border area to replace a group of armed border police officers, carrying out the tasks of cracking down transnational crimes. As important supporting roles, several other dogs would accompany their owners and come along.
