"System announcement! Great Qin has revoked the contract and received a 10% deduction to all stats!"
Since Zhao Fu dared to take the initiative to sign a Contract with the City Lords, he definitely left himself a way out. Ordinarily, Contracts were quite difficult to revoke, and what Zhao Fu had just drunk was Contract-Revoking Water. However, because what they used was a special contract, Great Qin still received some penalties.
However, it was only a 10% deduction to stats, which was not a great deal to Great Qin. After all, with Great Qin's various bonuses, they were still much more powerful than ordinary system main cities.
