From Lowborn Drug Slave to Martial God: It Starts with Testing Medicine!

A friend dies and entrusts Shen Lin with looking after his wife. As a lowly medicine slave, Shen Lin sees the man as an older brother, so of course he readily agrees to care for his sister-in-law.

But who could have guessed that his sister-in-law would actually...

Deep within the Marquis's residence, a gentle young mistress carrying mysterious Yin energy, and a pretty maid suffering from illness, both fall for Shen Lin.

The female owner of the medicine shop had planned to use Shen Lin to test a drug, but after getting drunk, the two of them... In the end, she even uses what happened to threaten Shen Lin into visiting her regularly.

He masters medicine, cultivates inner force, and breaks through the constraints of his meridians.

Moving among all kinds of beauties, he washes away his humiliation amid a chaotic age, takes up the martial path, and rises against the heavens.
