Under the investment road, Yingde unexpectedly took this vitamin with a good friend, and unexpectedly found that this pill not only had no side effects, but also made human feelings high! As a result, he decided not to be a good boy, and began to follow a crooked path to start a drug business. He wanted to fight for money every day and get high at parties every day. However, they never expected that their originally ordinary life would fall into the night world full of danger.
