A Family Together

What had gotten into Uncle Jin Long? He seemed unusually tense. This was the first time Su Bing had seen him in such a state. However, his attention was quickly diverted to the guest seated on the sofa. He didn't approach, instead, his gaze fell upon the visitor. The face was familiar, but who was it?

Gao Lang surmised that this must be the young prodigy, Su Bing. He promptly introduced himself, "Hello, Su Bing. I am Gao Lang from the Guangcheng Research Institute. I would like to invite you to join our preparatory class. Of course, I am aware that you have already accepted an invitation from the Youth Research Class, but we would still like you to consider our offer after understanding more about us."
