Traveling to another world, I didn't want to become a royal guard. Kill thirty-six heinous gangsters in one year, the system is activated! The second level of understanding the Thunder Sword Technique at the beginning of the ninth level! From now on! One sword and one step, one sword and one river and lake! Kill gangsters, annihilate bullies, slay the geniuses, annihilate evildoers, slay demons... Walk in the sky! There is nothing in this world that cannot be solved with one blow. If there is, then use another blow! Cruel! Decisive! Cunning! Both good and evil! With the sword in my hand, I will determine the laws of the world!
