MTL - Rebirth: Family Chaebol - Chapter 244 see off

Heavenly Pearl, an unknown mysterious, and heaven-defying object, for some reason, enter the heart of a young man named Ye Xiao who was framed and crippled by his fellow sect members for some unknown reasons and got kicked out from his sect.

Su Yan adored Xie Yu for many years and finally got what she wanted, but Xie Yu ran away on the wedding day, making her a laughing stock. At that time, Bai Xingfan appeared in front of her. He held a black umbrella in his skeletal hand to shield her from the heavy rain, and the other hand stretched out in front of her with a gentle and determined voice: “Don’t be afraid, still With me.” Su Yan was stunned with tears in her eyes for a long time, and finally, she reached out to Bai Xingfan.

However, it seemed like fate had decided to play a cruel trick on him.

One year later, the Recuperation of Reiki… did not happen as expected.
