The story begins with a letter, which was a letter sent by Mo Bai five years ago to Mo Bai now. But Mo Bai had no impression of this letter at all. The content of the letter was a set of passwords. Mo Bai created his own password. The content of the password was an address. Mo Bai found "his son" at this address, and then he received a second letter arranged by himself. It was also a set of passwords. The content of the password asked him to kill "his son".
...
Mo Bai was so angry that he wanted to vomit blood and shouted at the person in front of him: "Without me, you wouldn't have lived to be seven years old." "What about you? Over the years, I have saved you hundreds if not thousands of times. Without me, you would have died long ago."
"Mo Bai, I don't owe you, we are settled!" Mo Li yelled these words with veins popping up on his forehead, and the world suddenly became quiet.
