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!”

Hence, after a certain stage, it would be impossible for ordinary Daoyuan realm experts to continue extending and expanding their Dao paths.

They were lacking in comprehension, and had to transcend nine Great Dao calamities in order to strengthen and perfect their Dao paths before they could become stronger again.

Although they could continue to extend and expand their Dao paths by severing the source of their Dao paths from the Great Dao, the resulting Dao path would be weaker than the Dao path that was created by relying on the Great Dao of the nine zones.

It was just that they were no longer restricted by the Great Dao of the nine zones. Once they ran out of comprehension, their growth would stagnate, and they would have to obtain new insights into the Great Dao and its laws to continue extending and expanding their Dao path.
