When Yan Yu was 18 or 19 years old, his younger half-brother had died from a severe illness. He did not know if his stepmother had started to behave erratically because of the death of her son.
Having become the only son of his father, his situation at home began to improve gradually.
For some reason, he had a falling out with Chu Guodong, who soon afterward joined the military.
It was confirmed that Yan Yu was connected to the drug traffickers. Chu Guodong had accidentally discovered Yan Yu's association with someone involved in a mission from years ago, someone who had detected the drug trafficking group's activity and had recommended sending their squad to tackle it.
But just for this reason alone, Chu Guodong still couldn't confirm the extent of Yan Yu's involvement. After all, knowing a few mutual acquaintances in the same compound was nothing unusual.
