"What could have allowed them to improve their cultivation so much in just a few years?" Lin Xuan was very curious.
"I don't know either, you'll have to investigate it yourself."
"Go on, return to Tian Nan Domain early. Maybe by the time you come back, I'll have come out of seclusion." Lin Zhan's figure gradually faded.
"Oh, right, Father, I have a few Undying Golden Pills here, I'll give you and Mother two each." Lin Xuan started to take out his Storage Ring.
"I have no use for those, you keep them for yourself." Lin Zhan shook his head slightly, and then his figure completely disappeared.
"Left already?"
Lin Xuan felt a bit lost, after all, it had been nearly four or five years since he had last seen his parents.
"Never mind, Father is already a King, with a lifespan of two thousand years, and Mother also doesn't need to worry. I should hurry back to the Tian Nan Domain."
Lin Xuan moved, exiting the Mysterious World within his body.
