With Gu Shanhai here, and with the resources he provided, the Corpse King had no chance to make a comeback.
"No, I can serve you for a year at most, or else..."
Forcing the Corpse King to be a slave was naturally unacceptable.
"Alright, since we can't reach an agreement, let's just leave it." The Great Sky Rank said and took back the contract.
This was a good item, allowing him to contract with NPCs stronger than him across ranks. Generally, making an NPC a permanent summon required two conditions: one, a tool similar to a contract, and two, a success rate.
In general, the higher the NPC's level is compared to one's own, the lower the success rate.
However, the contract Gu Shanhai provided had a 100% success rate, which was remarkable since the Corpse King's level was much higher than the Great Sky Rank. So, for a long time, there was no need to worry about issues.
