Reborn as the Dragon Emperor, with My Lifespan Running Out?

Yu Ze opens his eyes to the Primordial Ancient Realm, where ancient ferocious creatures run rampant in every direction, the human race's traditions of cultivation flourish together, and the demon realm's heavenly court looks down proudly upon the primordial wilderness. There are also three thousand great realms, ten forbidden zones, and thirty-six sacred grounds! After transmigrating by accident, he becomes a Dragon Clan Emperor whose lifespan is nearing its end. In this world of survival of the fittest, he proceeds with extreme caution, sealing off the Dragon Clan's sacred land and extending the clan's lifespan by three thousand years. He also understands that without a new emperor, the Dragon Clan has already fallen into decline, and that he himself cannot hold on for much longer. During a fierce battle against an alien powerhouse invading the Dragon Clan's sacred land, the Immortal Dao Fruit finally awakens. Ancient remnants, the human race's cultivation traditions, the various races of the demon realm, and the masters of the forbidden zones all come after hearing the news, eager to gather and drink dragon blood! Yu Ze manifests a ten-thousand-zhang true dragon body and looks down proudly upon every direction! Master of a Forbidden Zone: “After all these years, that old dragon isn't dead. Why has he only grown younger?” Human Dao Lord: “It is merely a final resurgence before death.” Demon Emperor of the Heavenly Court: “This is bad. That old dragon has actually been reborn through nirvana. He is bound to grow stronger and stronger. We must kill him immediately!”
