They had tried to reactivate the multicolored stones and return to Earth, but were shocked to discover that a huge amount of energy needed to be injected into the stone to do so.
Since they did not have that amount of energy, they could only wait until the multicolored stones absorbed the energy from the surroundings to replenish itself.
Furthermore, they found out from the stones that even if they teleported back to Earth, when they entered the world again, they would return to the same place.
Thus, they had to first escape this place before teleporting out. In the end, the Lord of Hell, Yu Shen, and Ao Changkong all obediently became miners.
The person in charge of guiding them was an old miner who had reached the Immortal King Realm.
He looked at the three of them and grinned.
"You guys are the most awesome miners I've ever seen."
