From Rebellious House Slave to Martial Saint of the Mortal Realm!

[System] [Decisive and Ruthless] [Feel-Good Read] [Multiple Female Leads] Lu Chen transmigrates into the body of an old servant who dares to defy his master. Not only has the servant developed improper desires for the young lady of the Gu family, he has even joined forces with outsiders, hoping to destroy the Gu family together.

In this world, strength speaks for itself. Lu Chen knows that this so-called alliance is merely wishful thinking on his predecessor's part. Once the other party arrives and gets what they want, he will certainly be the first to die.
