After questioning He Chengfeng, Chen Lin learned why he wanted to enter the Ancient Kingdom Ruins.
He Chengfeng had said he wanted to find his father, and that was part of it. But his greater reason was to reach Core Formation!
Chen Lin had made the reward clear: anyone who brought out the information he needed would receive triple the reward. He Chengfeng already had good aptitude and had reached Foundation Establishment before forty. With those resources, he stood a strong chance of reaching Core Formation.
As for why he was so desperate that he would risk certain death, the reason was rather melodramatic.
His childhood sweetheart had found a higher branch to perch on: a Foundation Establishment Late Stage Cultivator whose lineage was stronger than the He family. Humiliated by the broken engagement, He Chengfeng had not dared say a word. Now he wanted to make a comeback and prove that the river ran east for thirty years, then west for thirty more.
Another reason was He Chengfeng's extraordinary powers of observation. He seemed to possess some invisible Talent Ability that made him adept at reading people, discerning terrain, and even sensing spatial directions.
Such an ability would be useful for exploring the Ancient Kingdom Ruins. He had long wanted to explore the place but had kept hesitating. The moment Task One appeared, he was tempted. His father's disappearance inside had sealed his resolve and given him a reason to act.
Once Chen Lin understood all this, he stopped concerning himself with He Chengfeng's motives.
The man's loves and grudges had nothing to do with him. As long as He Chengfeng had no other designs and caused him no trouble, that was enough.
If He Chengfeng completed the task, all the promised rewards would be his. If he failed
