Become the King at the Beginning, Shoot Out the Gun and Chase the Clouds

[Single heroine + boss + world war + gun + decisive killing + non-toxic points] When different worlds collide, war begins. This is not only the encounter of worlds, but also the collision of practice systems and the friction of ideas. The strong are always strong. If you want to survive, you have to become stronger. Worlds continue to collide, merge, devour, and evolve. This is a cruel law. When mountains and rivers are broken, there are always those who step forward to save the people from the fire and water. There is a sword fairy who shines in nineteen states with his sword, there is a scholar who becomes a king with a single thought, and there are countless people who have succeeded... Yes A spear pierces the night and penetrates the dawn (There are no poisonous points. Readers, please feel free to eat it. The protagonist does not have a particularly long development period. I sincerely hope that all readers will enjoy watching it.)
