Others Wake up the System, I Am Infected by Trojan Horse Virus

Thirteen years ago, Shen Du's father disappeared from the world. The police station found no such person, the school files disappeared, and even colleagues mentioned him as if they were describing someone who never existed. Thirteen years later, Shen Du was lying in the muddy water, dying. "Fool, you're not dead yet, hurry up and get some medicine!" I thought I had awakened the invincible system and would win life from now on. I didn't expect to encounter such a magic pill. What Shen Du wants to protect is no longer just his sister, but also the tomorrow that his father gave him.
