A Salted Fish Wants to Turn Over

In the 14th year of the Ming Dynasty, that is, in 1449, Emperor Yingzong of the Ming Dynasty, Zhu Qizhen, was instigated by the eunuch Wang Zhen and decided to conquer Oara in person. However, he was besieged by the Oara army in Tumubao. Just when the Ming army was about to run out of ammunition and food, a strange force suddenly appeared from the rear of the Wasi army, and together with the Ming army in Tumubao, they attacked the Wasi army. The Ming army won a great victory. In the year 2000 AD, the world was in chaos. A sudden incident plunged the whole world into panic. It turns out that high-latitude creatures have set a rule for humans on earth, that is, one human from each country must be selected as a contestant to participate in a game every year. The game lasts for an unlimited time until someone clears the level. The winner gets all the kills and the loser gets nothing. In an instant, every country fell into panic and surprise.
