Japan invaded the Central Plain over five years ago, and during these five years, led by the Demon Blade clan and the Fujiki Family, the Japanese forces successively captured a vast expanse of land.
Among them, the Flying Horse Dynasty lost five cities, the Daxia Dynasty lost six cities, and because the Bei Liang Dynasty was farther away, its losses were the least, losing three cities. As for the hundred countries of the Western Region, more than half of their territories lost control.
Although the Flying Horse Emperor deterred the master of the Demon Blade, there was still a significant gap in strength at the lower levels.
There was already confirmed intelligence that Japan controlled a drug that could stimulate human potential, and consuming it could significantly enhance one's power. Coupled with the Demon Blade's ability to manipulate hearts, the conquered armies and martial experts from the Central Plain feared death no more and won continuous victories.
