The Sumeru Treasure Mirror actually seems quite good. If it weren't for the fear of Ziwei Zi's tricks, even Tie Dan would really want to get a piece and play around with it.
After all, besides being able to scout, scan, and investigate the catastrophe site, this mirror can also split light into shadow, generating mirages and light effects. It directly serves as an Array Hub Treasure, maintaining the operation of the Array. Occasionally, the shadow of Ancestor Ziwang even emerges to offer guidance, pointing out where your lines went astray, helping you correct and check for wrong talismans. It's practically a supercomputer.
And the Penglai Three Brothers were originally Enlightened True Monarchs with profound Daoist practices, and with the aid of a Divine Artifact like the Sumeru Treasure Mirror, naturally, their actions are smooth and effortless.
