Seven Times Backtracking, Starting from Wizard Consumables and Becoming a God

The Shadow School, the bloody lair of dark wizards in the New World. Here, there is no training, only screening. The talented apprentices are tools, and the untalented apprentices are consumables. What awaits them is the dissecting table of the underground alchemy workshop, which is dismantled into flesh and blood and bones, refined into potions, and made into curse carriers. Lime Walker died on the cold autopsy table, and was replaced by a soul with [Soul Fire Embers], which brought him back to the day he was first admitted to the school. Seven times of time and space retrieval, each time he used it, the soul fire became weaker. The moment it was completely burned out, it was the moment when his soul was gone. But every time you go back, you bring back a little gift. The golden finger with restrictions made Lem put down all unrealistic ambitions, and only had one rule: to survive. The longer you live, the greater the benefits of looking back. What you are fighting for is not one life but eternity.
