Li Hao's proposal was accepted by the Yu Divine Dynasty.
Subsequently, a Divine Dynasty Prince came forth to invite Li Hao to the Emperor Hall of the Yu Divine Dynasty, where he was to leave a blood signature on the Emperor Stone Dragon Seal in order to become an official tribute of the Divine Dynasty.
When the Divine Dynasty faced difficulties, activating the Emperor Stone Dragon Seal could summon the tributes within the Divine Dynasty. If the tribute was unwilling to lend their power, they would suffer backlash from the Emperor Stone Dragon Seal, resulting in damage to their cultivation.
If the tribute was unable to attend in person, they could still respond to the call through the Emperor Stone Dragon Seal, projecting an avatar to participate in battle, thus contributing their strength.
In simple terms, this was akin to a sort of coercive contract.
