Overnight, countless underground cities rose from the ground and appeared on the surface. Tens of thousands of demons launched brutal attacks on human society. Swordsmen, ninjas, samurai, martial arts masters, qigong masters... No matter what kind of so-called 'human strong' they are, they have all become playthings in the hands of the 'devil'. The fall of humanity. From now on, Wherever my sword reaches, it is the country! With the members of my dimensional group, drive them all out!
