During the outbreak of the great catastrophe, the Cloud Continent first experienced the pollution of the Spirit Vein, which was later discovered by Li Zhirui. In order to gain Merit, he purified several Lands of Evil.
However, during this process, he found the situation here to be very complex, with wide-ranging connections, and other Mystic Immortal Cultivators blocking him, so he decided to leave.
To prevent the evil filth in the Cloud Continent from spreading and affecting the neighboring Mingzhou, Li Zhirui spread the Lotus Seed Skill far and wide, attracting a large number of Loose Cultivators and low-level cultivators to purify and resolve the evil filth here.
As for what happened later...
Li Zhirui isn't very clear, he only knows that after those Mystic Immortals left Cloud Continent, they went north, and later heard that when they left, they extracted the Spirit Vein of the Cloud Continent extensively, leaving little of the Spirit Vein's source.
