Not only did he possess spatial powers, he could also see the epitaph! [Epitaph: Do not dig up this coffin under the loess. Anyone who moves my bones will be cursed by the undead.

While everyone was still worrying about water, Su Heng had already traded the excess water... When everyone was digging carefully, Su Heng was already covered in equipment and roaming the world.
