Eighteen-year-old Lin Xi's biggest worry in life is that her wig and bangs are sticking up at the Comic Exhibition.
Until he was wearing a silver-gray cos suit and was swept into the ruins of Shibuya by a crack - in front of him was Hishito the Japanese knotweed, and in the distance was Gojo Satoru, with smoke floating in the sky and cursed spirits crawling on the ground.
And the model cane sword made of EVA in his hand became real.
"Mr. Silver Ash, please complete the mission: survive in this world and repair the world line."
... No, you have seen the system clearly, I am a coser
Good news: Silver Gray's face and temperament can really bluff people.
Bad news: He is eighteen years old, his real name is not "Silver Ash", and if he fails to complete the mission, he may never return home.
Now he carries an exquisite cane sword, a system that can only issue tasks, and a cos suit with a guilty conscience under the cloak. He draws his sword to save people at crisis scenes in various worlds, and then is regarded as a "mysterious Western swordsman", a "lost magician", and a "retired killer"...
Lin Xi's hand in drawing the sword became more and more stable, and the time he spent playing the role of "swordsman in the snow" became longer and longer, so long that sometimes he would forget who he was. But he meets some friends in every world.
Lin Xi finally completed all the tasks.
The system was floating in the air and looked at him, as familiar as a dream he had had for a long time.
"You finally remembered," he said, "Doctor."
——Wait a minute, who is the doctor?
Intention: If the footprints of life will one day be buried in the dust of time, then we can never stop.
