Thinking that Robinson William could not finish the test as quickly as he had, Dong Tianyu did not accompany him throughout.
After settling his parents, Dong Tianyu quickly bid them farewell. Bringing his parents over had delayed him by several days.
Although he entered the Cave every day for cultivation and did not miss out on cultivation time, it still affected Dong Tianyu's progress in collecting Mysterious Cores.
Furthermore, with aquatic creatures now emerging in the water, Dong Tianyu thought it best to leave as soon as possible, so as not to affect the upgrading speed of his Companion Spiritual Treasure.
Once his parents were settled, Dong Tianyu had no new concerns, so it was time to resume his adventures.
After leaving enough supplies for his parents, Dong Tianyu resolvedly left the place.
When Chester came looking for Dong Tianyu, he learned from Mr. Thompson that Dong Tianyu had already left to seek his fortune.
