MTL - Serious People, Who is Learning Magic at Marvel? - v16 Chapter 99 Return of the Wailer (End, 6k)

To take a dragon's hoard is to challenge death.The greatest of the sea-drakes wakes, curled on his silver throne; but there is no silver. His hoard is stolen. He rises, screaming, and chases the thief to the ends of the world—only to be shot from the sky.But dragons do not die easy, and never one with such festering hatred. A dungeon core rises from his corpse.If he intends to survive so near the cove of pirates that slew his past self, he'll need to master his powers—and quickly. For these pirates are dragonslayers; they won't be felled by mere mushrooms or spiders.Beneath the lawless Calarata, the young dungeon core will have to fight to survive; and one day, he will return death to the man who killed him.

Tan Shuchang had always considered himself born into a scholarly family and had also been a young star atop the honor roll, a true parasite of the upper class. He should have been holding significant local authority, receiving endless gifts, spending boundless money, enjoying innumerable years, and marrying countless concubines. How had he ended up becoming a demonic cultivator? After pondering for a long time and still not understanding, he slowly emerged from the pool of blood, deciding to think it over gradually…

He is a young man without a spirit root. It is believed that this denies him the chance at cultivation. However, a mysterious lady imparts a Supreme Demon Classic to him and from then on, he starts his path of cultivation.
He undergoes a total transformation to emerge as the most fearsome and powerful fiendish demon in his era, that even immortals and fiends are fearful of him, and saints are at his beck and call.
Mastering the Supreme Demon Classic is the turning point in his life. He is able to unleash his immense and divine power from within, illuminating the entire universe!
