There is space for those who travel between the two worlds. Materials from the two worlds are resold. The protagonist lives in the 1980s and can travel to 2025. Lin Chen is eighteen years old. His parents died young and he lives in the house of his mean uncle. He does not have enough food and clothing to do the heaviest farm work. He is looked down upon and regarded as a burden by the villagers. After the college entrance examination resumed, he tried his best to prepare for the college entrance examination, but because Big Burke withheld rations and deliberately made things difficult, he missed the opportunity to take the college entrance examination and fell into a desperate situation. He accidentally touched an ancestral, rusty bronze jade pendant on the beam of his ancestral house.
