The only reason Ye Tianling wanted to forcefully kill Bai Changxi was his instinct: if this man lived, he would inevitably ruin things one day!
Bai Changxi was not yet a significant threat. However, in this world, anything was possible! Even the laws of a star domain could change. Even the cosmos could shatter and be repaired. Therefore, the possibility of a Divine Son-level genius like Bai Changxi unexpectedly rising to power was simply too high.
Furthermore, for Ye Tianling, using the Time Law to pierce through the void between two worlds to kill someone was an experiment in his comprehension of the laws! He needed to find a cultivator to serve as a sacrifice for his sword. This cultivator couldn't be too weak, nor too strong! If they were too strong, he wouldn't be able to kill them. If they were too weak, killing them in reality would be meaningless. Bai Changxi fit the criteria perfectly.
