Ming Linyuan knew the contents of the negotiation. Setting aside the rest, the mere thirty billion Demon Crystals were enough to make him want to curse his father.
Zi Qi really dared to ask for so much! And the old geezer actually dared to agree!
Even though the payment was spread over 30 years, with one billion per year, it was still quite ruthless.
And it was divided among the Demon Kings, two billion each. The first year it would be taken from the third Demon King's inheritance, just enough to cover it.
But the second year it would be his turn! Following the order 3456712...
When the other Demon Kings found out, they regretted immensely not helping the third Demon King.
But it was a done deal. If they didn't want to pay, the only option would be to keep fighting. Seeing that old guy licking boots, afraid of offending the Beast Emperor, they all lost their spirit.
They might as well mine obediently.
