Half a clear breeze

Chu Xuan transmigrated to a fantasy world and became the young master of a powerful family. He was rebuked for misbehaving just because he sneezed during a banquet. As punishment, he was banished from the ancestral mansion and was relocated to a remote residence.
He did not mind the punishment at all. He just needed a spot that could allow him to be a shut-in. With the system that would allow him to grow stronger by being a shut-in, the longer he stayed indoors, the more powerful he became.
After being a shut-in for a day, he was rewarded with the Indestructible Body Technique.
After being a shut-in for a month, he was rewarded with the Immovable Mountain Technique.
After being a shut-in for a year, he was rewarded with the Yuxu Celestial Scripture and 100 years of cultivation.
After being a shut-in for 10 years, he was rewarded with the Chaotic Indestructible Body and the Bell of Chaos.
…
Chu Xuan declared, “No one can make me leave my home. I like being a shut-in!”

I Stayed At Home For A Century, When I Emerged I Was Invincible

Chu Xuan examined the leaf. It contained the laws of the Great Dao, and could temper and accelerate the transformation of Dao principles, as well as speed up one's Dao realm cultivation progress.

It was even helpful in comprehending Dao principles.

It was a good treasure that even had some use at the Daoyuan realm, as it could strengthen one's Dao path, at least up to the 10,000-mile mark.

Chu Xuan returned the jade crystal palace to Fengkong, and allowed Demon Buddha to keep the leaf. This was his disciple's opportunity.

In any case, he had treasures of that level himself.

The leaf entered Demon Buddha's body, and Chu Xuan said, "This is a pretty good treasure. It's helpful for cultivation. Even those at the Daoyuan realm will have a use for it."

This made Demon Buddha extremely excited.
