In order to find his granddaughter, the old man risked his life.
The arrival of the old man alerted the leaders of Cheli City. The leaders of Cheli City's Narcotics Brigade and the Criminal Investigation Unit were summoned to the city for a meeting on the same day. They returned to their respective bureaus with the orders from the higher-ups.
Lina's appearance became the key to whether they could find the old man's granddaughter. The two groups of people from the Narcotics Brigade and the Criminal Investigation Unit were all involved in the case of finding Lina's whereabouts.
Cheli City's narcotics police didn't give up. They continued to check the various border surveillance cameras carefully. In order to find the whereabouts of this person so that the entire case could progress, the narcotics police who patrolled during the day would cooperate with their colleagues to check the surveillance cameras when they returned to the team at night.
