Overlimit Skill Holder (Web Novel JP)

In a world where individuals are allotted eight skill slots, encompassing everything from basic strength enhancements to potent, coveted abilities, a young man labors in the depths of the Orb Mine. He and his fellow "slaves" are denied access to these essential skills by the oppressive Coact Magic, forcing them into a life of servitude. However, this bleak existence is abruptly disrupted by a catastrophic earthquake that causes the mine to collapse. Coincidentally, their cruel noble master, the landowner, perishes in the disaster, instantly dissolving the magical constraints holding the slaves captive. A chaotic scramble ensues as the remaining slaves seize this unexpected opportunity. They greedily claim powerful skill orbs, overpower the guards, and escape to freedom. Our protagonist, tragically, is too slow to react, his hopes dwindling as despair washes over him.
