My Insectoid Race Rules Over All the Heavens

(No harem, overwhelming victories, an invincible path, slow burn, hot-blooded, long-form, frequent updates) Jiang Shaowen, an ordinary man, relies on his talents and troops to fight his way through the Thirty-Third Heaven and onto the battlefield among the stars. There he meets the Guardian and takes his place, protecting the universe. Thirty thousand years later, he fights his way out of the universe, passes through a black hole, and eternally subdues the myriad worlds.

Background: The universe has long been under attack from the Dark World. The Guardian is the strongest being in the current universe, and has suppressed the myriad worlds for countless millennia. In the end, however, he succumbs to the corruption of darkness. Sacrificing his own life and that of his troops, he uses his will to buy the universe ten thousand years, waiting for a new Lord of the Universe to be born and find a way to defeat the darkness.
