Seven days later, Han Yi finally found his original point of arrival. Then, he delved into the Emperor Fallen Sky Pond.
Half a month later, he found the marker for the fifth island.
During this half month, Han Yi encountered many cultivators. There were fewer half-immortals, most were in the middle stage of spirit transformation, and a few were in the nascent soul stage.
From one of the nascent soul cultivators, he learned about the anomalies occurring in the Emperor Fallen Sky Pond and discovered that the four polar powers of the Daluo Immortal Realm, ordered by their ancestors, had sent high-ranking immortals to investigate.
