Lin Jing indeed entertained the idea of leaving descendants on Earth.
However, it wasn't through traditional means of procreation, but through alternative methods.
For example, the mutated Spirit Spring water, after a secondary synthesis upgrade, could directly allow one to have descendants.
Or, simulating demon beasts with bloodlines above ancestral levels, and propagating a part of their bloodline origin into bloodline-inherited offspring, to have descendants.
In short, if he really wanted to, there were many methods, and the causal entanglement would be minimal.
However, these thoughts came about because he was affected by his surroundings at the time, worried that after he left again, his parents would miss him, so he wanted to leave them something to remember him by.
But after careful consideration, Lin Jing felt that doing so would be somewhat irresponsible towards his descendants; being born without a mother, and also without a father, was not the best choice.
