Long ago, Ji Xinghe said he wanted to kill it.
But now that it thinks this way, there's no problem, and it has every reason to do so.
"I was only at the Sixth Stage back then; there were far more than one that could replace me. As for the secret of the inheritance, or rather, the second method of inheritance, you could completely keep it secret. Even if you needed a hundred thousand gifts, with your control over the Empire, you could easily carry it out in the shadows.
If that's the case, Ji Xinghe couldn't possibly know that there are two methods of inheritance, with the latter not requiring death. He indeed doesn't need to worry about the Gods' Blood being poisonous, but that has nothing to do with the inheritance. The abilities he possesses will always be his alone; the Federation won't see a second person like him, not even Li Yuanba.
