The last level 1 spider captain standing was none other than the purple-striped water spider.
Leo intentionally didn't kill it because he wanted to play with it for some time until the other water spiders arrived.
"What do you want? Why didn't you kill me?"
Even though it was fearful that Leo didn't kill it, it felt a little hopeful because as long as it stalled for some time, the level 2 spider captains and generals would come to its rescue.
"Didn't I say I want a rematch?"
Leo slowly walked towards the purple-striped water spider and replied.
"I admit defeat. You are the winner. Let me live."
Whether it was a human or a beast, which living being wants to get killed? As soon as it heard Leo's words, the purple-striped water spider admitted defeat.
After seeing how easily Leo killed the night supreme-ranked water spiders, the purple-striped water spider didn't have any hope of defeating Leo. Hence, without any hesitation, it admitted defeat.
