Jiang Chen agreed for some reason.
The bronze cauldron was a treasure of the Black Yellow Great World. In the system of weapons, after putting the fragments he had collected together, what he had could be compared to a Holy Artifact.
However, the bronze cauldron was not a weapon used to attack.
All of its wonderful uses had been developed by Jiang Chen.
For example, he could increase or decrease its size, and it could be used for defense. In fact, it was kind of slow in attacks.
It could attack average Martial-level strong people by surprising them and smashing them to death.
But the Demon King before him was obviously not average.
It had worked before because the Demon King was too proud, and he chose to fight the bronze cauldron despite its difficulty.
As long as Demon Kings who could learn a lesson knew how to avoid it, it would be difficult for the bronze cauldron to inflict harm on them.
