In an era when the power of Fire Magic was considered to have reached its limit, one girl began researching nuclear fusion.

One of the few self-cultivator who exist in this modern world; due to an unfortunate event, completely destroyed his body in an explosion. Using all his effort to save his primordial spirit, he ended up in an strange magical world and had to start all over again. From a fallen aristocrat to the Warlord of Chaos, this can no longer be summarise as legendary; this is the life of the God of War.

Yang Ye’s entire family relied on him to keep them safe, but just when everything seemed to be going well, misfortune struck in droves!
