The thing on Earth before, he was preparing to kill people, and any ordinary Minor Heavenly Position character who encountered it would basically die. Its lethality is extremely terrifying, but the only pity is that there's just one of them, and it's a single entity.
In other words, this thing can only be used to kill one person. Once it kills, it's gone.

It must be understood that even he, at the time, only by coincidence because of Pei Wanning, managed to gather all the materials needed to make that thing completely...
