Gu Beichen transmigrated to another world and became the personal groom and armed bodyguard of the Prince of Zhenbei's household.
The old prince had died in battle at the border. Wolves circled the princely household, while relatives from every branch of the family watched covetously.
The stunning princess consort, alluring and powerful enough to control half the city, summoned him to her bedroom. "Beichen, the princely household has no heir. This princess consort needs you to do me a small favor."
Gu Beichen backed away again and again. "Your Highness, I'm only a bodyguard. Please behave with dignity!"
The princess consort gave him a flirtatious look. "How can a personal bodyguard not get personal?"
He awakened the Family-Guarding Martial Saint System. As long as he protected the women of the household and helped the family grow stronger, he could gain limitless boosts to his cultivation!
By day, he could cut down rebellious villains who came to force their way into the palace, shaking the capital with his might.
By night, the princess consort's door would quietly crack open...
"Guard Gu, there's an assassin in my room. Come protect me up close!"
