Baptism.

The two girls cooperated to get the fruit from the top of the tree. Shi Lang watched as Hao Mei lifted Yu Xiedi with her palms. The latter hung from the tree branch and pulled up Hao Mei. 

Yu Xiedi might be the younger one, but she was stronger regarding physical prowess. Shi Lang nodded and watched them carefully reach the tree's crown. Yu Xiedi was the first to pick a fruit, but she handed it to Hao Mei. It just so happened that the elder one had also picked up a fruit from her side of the crown and turned to give it to Yu Xiedi. 

The two girls smiled and climbed down the tree as they had climbed it. The girls came up to Shi Lang and extended their hands. The terran said, "Eat it. I have consumed it once in the past. One person can only have this fruit once in their life. Eating any more will be a waste of time."
