If Chu Hao had opened his eyes at that moment, he would have recognized at least one person in this group.
Qin Chou!
This was the troop from the Qin Family, a family that claimed to be the foremost power in Qin State, a name derived from this very family. Qin State was also the strongest among the Nine States, making the Qin Family's power undeniable.
The history of the Qin Family was ancient, as the state was named after their family surname, showing their traceable lineage into the distant past. Therefore, in the records of this family, there were snippets about the Nether Palace, vaguely mentioning the Secret of Eternal Life.
Thus, once they learned of the Nether Palace's opening, the Qin Family immediately dispatched its forces.
The group of seven, led by Qin Chou, was just one part of a vast contingent — the Qin Family had dispatched over three hundred people, divided into seven teams to cast a wide net and increase the chances of a fruitful haul.
