Dragon, I Handed You Over to the Country, and Now I Rule Another World

Drowned in a river before his college entrance exams, Long Ze transmigrates to an otherworld overrun by dragon beasts, where he becomes a white Yinglong who can control electricity. The catch? He has only ten days left to live!

Fortunately, he binds to an interdimensional trading System and takes dragon crystals back to Blue Star to seek a partnership with his country. He trades dragon beast cores for electricity to extend his life, then ships Blue Star's weapons to the otherworld to hunt giant beasts, as well as dragon hunters whose extraordinary powers have awakened and who pose a threat to his safety.

Just as he earns enough life span, he forms a contract with a breathtaking dragon girl who can amplify his power. But who would have guessed that her identity is actually...

Then the military hands him a top-secret file: the remains of a dragon crash from twenty years ago, whose scales look exactly like mine now...

Could this Yinglong body have nothing to do with a transmigration accident after all?
