Zhou Tian's strength was evident, even if he didn't actively fight back, he wasn't someone anyone could easily harm. If Zhou Tian was truly pushed into a corner, with some sacrifices, none of the elves besieging him at the moment could expect to walk away alive.
As creatures of equal standing, even though the elves were not as strong as Zhou Tian, they could still sense his dangerousness. Once they had seen Zhou Tian's actions, they naturally realized that this time they had likely bitten off more than they could chew.
A strong figure like Zhou Tian would be treated with respect wherever he went. Although Zhou Tian's entry had aroused the elves' hostility, regardless of that fact, judging by Zhou Tian's power, the leading elf understood that Zhou Tian was not ordinary. As to someone as strong as Zhou Tian, even if she initially received an order to kill him, at this time, she absolutely couldn't do that anymore.
