Thump, thump, thump.
Before Ji Dong and Yang Bingtian could catch up, the door was knocked. Zhu Rong's face darkened, but the door opened, revealing Zhu Lao Er with his messy red hair.
As soon as he entered, he bluntly said to Zhu Rong, "I knew, you would bring him here."
Zhu Rong replied with a frigid look on his face, "I am teaching my disciple, what are you doing here?"
Zhu Lao Er let out a smirk, "Just giving a heads up, be nice to my brother Ji Dong. We have become sworn brothers, old friends crossing age lines. Boss, you owe me this face."
Zhu Rong was stunned for a while, and even Yang Bingtian was dumbfounded, Ji Dong too was puzzled, were Zhu Lao Er and Zhu Rong close?
