Mervyn traveled through time and became a corpse collector on the battlefield, awakening the humblest golden finger: touching the corpse can inherit the ability and memory of the deceased - but the last wish must be fulfilled.
He originally just wanted to survive, but when he fulfilled his twelfth last wish, he discovered the terrifying truth:
The "talent" of this world is poison. The more powerful you are, the more your soul will be harvested after death; the "gods" are prisoners, locked underground by the Vatican to extract divine power; "civilization" is a breeding ground, and holy wars every hundred years are only to select high-quality soul crops.
And when Mervyn collected the poisoned saint and saw the transaction records between the Pope and the "Observer", he understood the meaning of the "Temple of the Past" deep in his soul:
"You're not the first Undertaker."
Now, it's his turn to make a choice - should he continue to live in the memory of the dead and witness the end of the world, or should he raise the sword inherited from thousands of dead people and fight against this mysterious existence that can even imprison gods?
"They gave me strength, they gave me memory, they gave me the eyes to see the truth."
"Now, it's my turn to give them an explanation."
