I've been home for a hundred years and I'm invincible when I go out

The young master of a powerful family who traveled through the fantasy world was reprimanded for misbehavior just because he sneezed during the banquet, and was sent out of his ancestral house to live in a remote courtyard.
Chu Xuan didn't care at all, as long as there was a place to stay, it was enough. With the system, the more you stay, the stronger the system, you only need to stay in to become stronger.
Staying at home for a day, rewarding King Kong's indestructible magic...
After staying at home for a month, the reward is immovable like a mountain...
After staying at home for a year, reward Jade Void Immortal Sutra + a hundred years of cultivation...
After ten years of residence, reward Chaos Immortal Body + Chaos Bell...
……
Chu Xuan said, no one wants me to go out, I just like to stay home!
