He Was Killed on the Night of Consummating the Marriage. I Was Reborn to Take Revenge on Gu Yuena.

Billions of years ago, Long Cang traveled across the Douluo Continent and cultivated into the ancient Cang Dragon body. Billions of years later, he and Gu Yuena met and fell in love in the Star Forest and made a lifelong promise. But after being together for millions of years, Gu Yuena didn't let Long Cang touch her in the slightest. The funny thing is that on the wedding night, Long Cang not only failed to get what he wanted, but was killed by the one he loved. That night, Gu Yuena showed her fangs! It turns out that she has been executing the plan to kill Long Cang, seize Dragon Yuan, and resurrect the Dragon God for millions of years! Long Cang is just a flag for her to play with her emotions. By a strange combination of circumstances, Long Cang was resurrected and became a copper-ringed worm with a lifespan of only three months in the Star Dou Forest. He awakens the system, evolves through devouring, and finally transforms into a dragon from an insect body! This time, he wants Gu Yuena to know the price of playing with a man's feelings! He wanted Gu Yuena to know how insignificant the little Silver Dragon King was in front of the ancient Canglong in its heyday!
