Transmigration: Raising the Child of the Male Lead Boss (WN) - Chapter 453

"Stay with me and I will give you everything your heart desires. For you, my darling, I would part the mountains, split the sea, and cause havoc on Earth just to have you."

Baek Yigang is a son of the Baek Clan, one of the seven great clans of Zhongyuan. Afflicted with the Taiyin Qi Blockage, he is cursed with a shortened lifespan and the inability to collect internal energy. He had been peacefully spending the rest of his days indoors when he was ambushed by a group of masked people. During the ambush, he lost his servant who was like a sister to him. Chased by the attackers, Baek Yigang escaped through a secret underground path. When he came across a blocked path, he decided he’d at least die fighting and picked up a rusted sword that was stuck in the ground…

The older young Lisko woke up and found that he had become an American. He took over his father’s ranch and began to live in the United States.
