In the massive mine before him, countless Cultivators were digging. They toiled day and night, each bound by shackles, forced to slave away under such conditions. Their cultivation levels weren't low, either. Most were at the Core Formation Stage, with the weakest at the Spirit Refining Stage. Using them for mining was clearly far more efficient.
At a glance, there were at least a thousand Cultivators imprisoned here to mine. 'I can't believe they were hiding such a large group of Cultivators here!' He had already rescued quite a few people, some from the Alchemy Room and others from the Forging Room. They had all been freed, but this place had been missed.
Who would have thought there'd be a mine here? To think that such a vast mine existed beneath the Netherworld Prison was astounding.
