It would be all too easy for the Dragon Temple to accomplish this; both Suo Lun and Yan Ziyu could be evaporated from this world.
Perhaps it would be a bit more troublesome with the Ashi Liren since he is a disciple of the King of Dongli.
But if it really were for a tremendous grand scheme, even a disciple of the King of Dongli could be evaporated from this world. After all, he is only a disciple, not a son.
If that's the case, why would this Fake Zuo Qiu bother to disguise himself to meet with me? Isn't this superfluous?
He hasn't left the Relic Castle for several years, and there is no doubt leaving once would incur a huge cost.
The most cost-effective way would be to simply kill me, so why not do it that way? Instead, he chose a higher-cost, higher-risk approach by meeting with me and persuading me to give up on my action against Ashi Luo.
Moreover, there is a risk of being exposed in meeting me.
