Hi guys! I hope someone can help me to find this novel. I don't remember much. New sect disciples had to choose tasks and MC choses to go to planting pavilion. Elder of planting pavilion decides to make him his successor. Later, the elder takes MC with him to secret realm where MC stays there until it opens again. I think he felt into the water there because he was attacked, but found inheritance. I think he also saves a daughter of sect master from being raped. After the secret realm, he decides not to go back to the sect, but to travel to another continent on a ship. There was a safety agreement between a sea king and some sect, but rebellious sea monsters attacked the ship.
