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

Under the blessing of the Sagemaster's Halo, Su Xian'er and the others were all immersed in a state of comprehension.

It was not difficult to grasp the basics of array formations.

After the explanation was finished, everyone achieved their own level of mastery.

Chu Xuan passed the complete Heaven-reaching Sword technique to Ding Yue. He had originally wanted to wait until Ding Yue broke through to the Heaven realm before teaching him the full technique, but with Ding Yue's recent achievements in Sword Dao comprehension allowed him to do this in advance.

Su Xian'er and Ding Yue returned to the pocket dimension and tried to set up their own array formations.

He had gained some new insights into how to use the array formations to help refine pills, and even how to refine array formations into pills, transforming pills into weapons that could kill enemies.
