later the cake is still mauk hours is still less than half an hour away, replied li yin

.....

change day.

"Grandfather, I'm back!" When Li Yin stepped into the old house, she suddenly felt sour. Since his grandfather died, he had returned to school in NJ City, and now a year had passed, and he had returned to this city. This old house.

Pushing open the side room door, the portrait of grandfather was still on the altar. The friendly smile on the photo was the same as when he was alive. He hasn't been back in a year. A thin layer of dust has fallen on the portrait. Feeling guilty, I took the photo and wiped it with my clothes.

Only after graduating this year did Li Yin return to SH city. After much deliberation, he decided to return here to look for a job. The old house is in the suburbs of SH, not far from the subway station. The transportation is very convenient, and this is an ideal place. It also saved her from the problem of renting a house, allowing her to find work with peace of mind.

After paying his respects to his grandfather, Li Yin began to tidy up the old house. After all, that old house was where he lived, and could not be left as quiet as it used to be. Holding a broom, Li Yin started cleaning the old house.

........

Recalling the days when she and her grandfather lived together, Li Yin went to her grandfather's former bedroom and took a broom to clean the bottom of the bed. Right now, he was sweeping the yellowed envelope with a broom.

Slightly frowning, Li Yin suddenly recalled the night before her grandfather died. He pointed to the bed and continued to say "letters". Back then, being too sad, Li Yin did not care at all, then sent her grandfather to the hospital. A funeral or something made her completely forget about it.

Squeezing the envelope, Li Yin felt a ring-shaped hard object, which looked like a ring. He tore the envelope and looked, and it turned out that it was a bronze ring located at the bottom of the envelope.

Pouring the ring, Li Yin unfolded the letter paper and looked at it, but this view completely subverted Li Yin's worldview.

In the letter, Li Yin's grandfather said that he was not from this world, and Li Yin was not his grandson, but a child he had picked up. The world he lived in before was a place with highly advanced space technology, and he used to be the world's top scientist, the failure of space experiments brought him to Earth.

For decades, he had tried to restore the tunnel of space and time back with technology in his hands, but when he spent decades of hard work and thought he had succeeded, he failed again. What he came to was not the original world, but another space and time.

The letters slipped out of Li Yin's hands one by one. He's in a mess right now. He never imagined that the plot that only appeared in this novel actually appeared in his own life.

Grandfather would never joke with him before he died, so all of this must be true. Thinking of this, Li Yin looked at the ancient well in the backyard.
