The Kingdom of Shireck ultimately signed the peace treaty, agreeing to all demands of Tang Country, including compensating Tang Country with 300,000 laborers as well as a payment of 100 million Gold Coins.
Everyone knew well that the Kingdom of Shireck simply didn't have the funds to compensate Tang Country, yet they had no choice but to sign the peace treaty.
Beyond that, the Kingdom of Shireck was also reluctantly the first country in the world to recognize Tang Country's conquest of Qi Country. They acknowledged Tang Country's occupation of Qi Country, disgracefully including a petition urging Tang Mo to declare himself Emperor.
The Dahua Empire was firstly very dissatisfied with the petition since Zhao Kai definitely didn't want to see a so-called empire emerging on his nation's border, nor an Emperor who would be his equal in status.
