He originally wanted to rely on the system to complete the main tasks step by step and return to the original world, but he fell in love with her in the big world. She was the princess of the subjugated country and his junior sister. He originally only needed to form a Taoist couple with Senior Sister Qing Leng to destroy the devil and complete the mission. But he was willing to deviate from the main line and go against the trend for her alone.
"If one day I look old and my hair turns white, will you still love me?"
"The sea has dried up and the rocks have rotted away, but you are still young and beautiful."
Purpose: When the destined fate runs counter to the one he loves, he chooses to change his fate against the will of nature, using his body as cannon fodder to protect a person's youth, and write an ending that belongs to them based on the rules.
