Immortality Depends on Illness, and Strengthening Depends on Attacks!

Ning Yunfeng has a very special illness. When others get sick, they are weak and decayed, but once the protagonist is infected with this certain virus, his body functions undergo strange changes. The cells in his body seemed to be activated by a mysterious force and began to repair and strengthen themselves in a special way. Although he looked sick on the surface, he was actually able to absorb the mysterious aura of heaven and earth that no one could control and transform it into his own vitality. After a lot of training, he finally became the sick emperor. After tens of thousands of years, the original ancient fantasy world has transformed into today's technologically advanced urban world. Ning Qiufeng is located in a secret realm, and the entrance to the secret realm is the "Illusion Realm Mountain" guarded by his descendants. Later, the world changed, and demons stronger than Ning Yunfeng appeared in the world. Ning Yunfeng was unable to spend most of his life to resist the temporary seal, so he only had 30 years left to live, but his cultivation remained unchanged. In these 30 years, he must find the descendants of those viruses to get sick again and rebuild his body! This novel and its characters are purely fictitious.
