"Brother, I wouldn't have minded if you took my coffin savings, but to destroy my body? That's too much. These three needles cost me a fortune. Come join me, dead as I am. Hahaha!"
Mu Ying: "..."
However, how could the tomb owner be so eccentric?
So the mechanism hiding the box was in the corpse, and only when the corpse was damaged would the box appear to strike its opener.
But he probably didn't anticipate that the once-ordinary bronze coffin, due to the disappearance of Guland Underground City, had skyrocketed in value.
Tomb raiders wouldn't even spare the coffins.
Then there were people like Mu Ying, who moved his body along with the coffin and were excessively cautious, using such thick and large stone slabs for protection while opening a tiny box.
If the tomb owner still had any consciousness, he'd probably be so angry his skeletal frame would shatter.
