Lin Yuan. A doctor in materials science and biochemistry in the 21st century traveled back to a courtyard house in the 1960s due to an experimental accident and became a young man whose parents died, leaving only one room and a meager pension. He has a calm and rational personality, and believes in "if someone offends me, he will repay you tenfold." His acting style is decisive and decisive, and he will never be sloppy.
Goldfinger: An inconspicuous bronze ring among the relics of his parents. Lin Yuan's blood accidentally activated it, opening a one-way passage to the "Collapse Fairyland". This fairy world is dead, the spiritual energy has completely dissipated, the sky is gray, and the earth is full of cracks. There is no inheritance of skills and no living creatures here, only:
"Garbage" resources: dead elixirs (still contain weak but far superior special ingredients to Earth's plants), skeletons of giant beasts (unusual bone density and composition), metal fragments from broken magic weapons (with special physical properties), "spiritual soil" in the spiritual field that has turned into mortal earth (but it is the top fertilizer on the earth).
