Kai Syaoran felt his qi flow unhindered without any outside interference. The bolt of lightning did not wait for him to enjoy this feeling before it struck with all its destructive might. The power contained within the bolt was enough to kill an emperor realm cultivator on first contact.
All living beings were clear that this was not a tribulation but an annihilation. This judgement from the heavens served to reinforce the image that most humans held about demonic beasts. They were abominations of heaven and earth. They were an inferior race.
The moment the bolt landed on Kai Syaoran, he did not defend himself or try to escape. He channelled the bolt into his body and let it move on its own without his guidance. The bolt circulated through every inch of his body and when it was done, it went for his soul to finish the job. The only problem was that Kai Syaoran did not have a soul and he had probably never had one. The bolt entered his soul space before striking his Ego.
