Before the disfigurement, everyone loved Ling Chunan. After the disfigurement, Ling Chunan became a plague that everyone avoided. He was held on captive by his own agent afterwards because he was so ugly now, desecrating his love. Finally, Ling Chunan chewed himself to death because he was starving. After his death, a thing that claimed to be the counterattack system 098 found him.

A long time after, a certain counterattack system of a host with a 100% success rate posted a message in the System Forums.

Great God : No need. I have a fast recovering ability. I will let him bite me.
