Siheyuan: I Created a Biochemical Mother, and the Whole Courtyard Is Doomed

Xiao Dongsheng accidentally transmigrated to the early 1950s. He and his father fled famine for the capital, where they settled in a courtyard house.

Thanks to their superb medical skills, the father and son soon established themselves.

The residents of the courtyard had received plenty of help from the Xiao family.

But their good fortune did not last.

After Xiao Dongsheng came of age, someone arranged a marriage for him. His prospective bride was none other than Qin Huairu, a woman who knew just how to please a man.

But the Jia family, the He family, and the Xu family, all residents of the same courtyard, tried to steal the bride. Repaying kindness with treachery, they feigned illness and framed the Xiao family.

The Xiao family's reputation plummeted. They lost all the money they had saved, and Xiao Dongsheng even lost his job.

When he learned that Qin Huairu had gotten together with his enemy Jia Dongxu, Xiao Dongsheng's father fell ill and never recovered.

Then, on the day of their wedding, the System awakened.

It could cure any difficult illness with a single dose.

It could also inflict others with any pathogen it acquired.

From the start, he obtained HIV and turned Qin Huairu into a biological host.

Cancer, rabies, Alzheimer's...

With a single thought, he could send someone to heaven or hell. Xiao Dongsheng would make the entire courtyard die!
