I Couldn't Afford to Pay Off My Debt While Studying Medicine, so I Had to Work Part-Time as a Killer.

Su Han died suddenly while on duty in the hospital and traveled to the extraordinary era of the virus. He inherited a medical clinic in his small town that owed tens of millions of dollars. It is very poor here, without the blessing of high-tech weapons, only virus people infected by various viruses causing trouble everywhere. The Killer Alliance is the organization to solve this crisis. He originally thought that his life of poverty would last forever, but fortunately he could see the properties of various viruses, and coupled with his intelligence, he was able to swim in the water. Others were infected with the virus and suffered life and death, but he was different. He relied on refining the virus to improve his five senses and six consciousnesses, his seven orifices and eight meridians, and his bones and body. [Chenbo virus: prefers men and hates women, special gene fragments directly strengthen the body, no risk of death] [Spirit virus: likes the strong and hates the weak, special gene fragments enhance the five senses and six consciousnesses, causing death] [Strange virus: It likes dampness and hates people. The special gene fragment connects the seven orifices and eight meridians, causing death] Just very... When the virus comes, we become wage earners. … Of course, this can't get rid of the debt, so he hires killers part-time, and those infected virus people who lose their mental sanity become his perfect source of money.
