Breaking the Army with One Shot

In Tianwu City, a young man is practicing hard. On the way back to the forest, there is the key to heaven and the ancient dragon clan. Bearing the seal of the Dragon God, he ventured into the world alone. Northern Territory, Southern Territory, Overseas Islands. In the capital city, we are tired of overt and covert fighting. I just want to change my name to hate all the powerful people and kill all those who stand in my way. Returning to the world, rejoicing in grudges.
