Chen Shan wanted to say that there were only two people who bought oranges. However, the phone rang again.

"Master Lin reposted it. We're just helping him."

After he hung up the phone, Chen Xiaodong was stunned.

"Master Lin?"

"Son, who is this Master Lin?" Chen Shan was stunned by the repeated calls. He did not know what was going on.
