MTL - God Level Demon - Chapter 185 All for cultivation

Zorian is a teenage mage of humble birth and slightly above-average skill, attending his third year of education at Cyoria’s magical academy.

He is a driven and irritable young man, consumed by a desire to ensure his own future and free himself of the influence of his family, whom he resents for favoring his brothers over him. Consequently, he has no time for pointless distractions or paying attention to other people’s problems.

As it happens, time is something he is about to get plenty of. On the eve of the Cyoria’s annual summer festival, he is killed and brought back to the beginning of the month, just before he was about to take a train to Cyoria.

Suddenly trapped in a time loop with no clear end or exit, Zorian will have to look both within and without to unravel the mystery before him. And he does have to unravel it, for the time loop hadn’t been made for his sake and dangers lurk everywhere…

Repetition is the mother of learning, but Zorian will have to first make sure he survives to try again — in a world of magic, even a time traveler isn’t safe from those who wish him ill.

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!

If you do not wish to get dragged into the abyss.

The world had changed when the System arrived, alongside the Cataclysm that filled the world with monsters. The technology was gone, replaced by classes and skills that allowed the people to fight back. When Devon ended up as a Blacksmith, a class that didn’t grant Intelligence, he had to face the reality, that his old career that he loved - mathematical sociologist - was over. Instead, he had ended up as yet another discarded member of the production class, overshadowed by the existence of the System Shops to the point of total marginalization. But, what if all he needed was to reapply his scientific thinking to the System...
