Throughout the entire day, the old man had carried the barrel and entered and left the billiard hall three times. He had on inconspicuous clothing and nothing about him stood out in particular, so no one noticed him. It was quite a common job too, where people collected leftovers from restaurants or shops that served food. However, Tang Yan knew it was him, and he suspected that there was something in the old man's barrel.
It must be the reason why he entered and exited so frequently, perhaps to transport something.
In order to find out what it was, Tang Yan thought that he should put on a good show.
He could pull it off as he was disguised as a vagrant.
The last time he saw Feng Qiang coming out of the billiard hall, Tang Yan deliberately went to Feng Qiang's tricycle. He pretended to be hungry as he rushed to grab the barrel off the tricycle.
