Ever since his grandfather, Guo Ma, began to study the map drawn on animal skins, the family has been in disarray.

My grandmother's memory was getting worse and worse, and she often confused most things.

She hid hundreds of knick-knacks in a clay pot, salt, puppets, and some pale cyan stones. What fascinates Guo Yang the most is that in another clay pot of his grandmother, the eyeballs of various birds are stored.

My grandmother was a clever old woman, and she used to go to the woods behind the stockade, and whenever a bird flew in the sky, she only had to look at it, and the bird would fall and die.

The feathers of those birds are made into various dusters, vulture feather dusters, pheasant feather dusters, and pigeon feather dusters.

Every spring, these strange feather dusters bring back a lot of things for the family, the most important of which is salt and the brown liquid that grandfather used to write words.

Bird meat would be eaten alive by five or six or seven or eight aunts of Guo Yang, and the people of Tianshuizhai never cared about the specific numbers.

The bird bones would be sent to the stone room of his grandfather, Guo Ma, to be used as a source of reference for map research. Guo Ma insisted that only those beings who could fly could fully validate their research on the world and time.

The bird's eyeballs would be kept away by the grandmother, using a technique that no one knew about so that it would never seem to be corrupt.

Guo Yang once consulted his grandfather Guo Ma about the bird's eyeballs.

"It's as simple as soaking a bird's eyeball in a mineral-rich liquid for seven hundred and forty-nine days. Then, it is wrapped in heated pine resin, which slowly forms a hard shell. ”

Guo Ma didn't raise his head, and answered Guo Yang's question lightly.

"Slowing down time, or even pausing, is one of the most important propositions in all research." Guo Ma added, continuing to study the map.

Guo Yang didn't stay in his grandfather's room for long. In that room, there was an unbearable aura that would slow down one's breathing and slow down all movements.

He wanted to steal a few bird's eyeballs and put them in his small bottle while his grandmother was not looking. But it doesn't work every time.

My grandmother seemed to have lost patience with everything else, and she often forgot it in the blink of an eye. But only for those two ancient clay pots, I always remember them.

Moreover, Guo Yang was surprised to find that there was already some kind of extremely mysterious connection between his grandmother and the two clay pots.

Once, Guo Yang finally affirmed that the eyes of those birds were actually grandmother's eyes, and she was observing the world in another way.

"The sky is transparent, the clouds are watery, and the distance is slower than ours. We have been living in a false appearance. "My grandmother would often whisper something to the people of Tianshuizhai who didn't understand it at all.

……

In the spring, Wang Hai came again.

This time, he came alone.

In the middle of the night, Wang Hai stumbled into his grandfather Guo Ma's stone room.

He uncovered the skin that had enveloped most of his body, revealing a terrible wound.

He took out a bunch of things from a strange bag, a stove made of crucible, a spoon made of silver, a few sharp knives mixed with iron ore, a pile of firewood, a small bottle, and a large pile of plants.

"The world hurts each other and nourishes each other." Wang Hai trembled in pain, but he still said firmly.

The stove was lit, and he crumpled the plants into a ball and threw them into a square copper tripod.

The copper tripod was filled with a strange liquid, with a faint smell of blood.

He stirred the plants with a spoon made of silver, and kept taking out the vial, adding a red powder to the copper dome.

With a loud bang, the copper tripod suddenly exploded when the liquid was about to evaporate.

A huge wave of air lifted the roof of his grandfather Guo Ma, revealing a small starry sky.

A smell of sour rot enveloped the entire Tianshui Village, and everyone ran into the river to wash their bodies constantly.

The elderly, children, men, women, except for their grandfather Guo Ma and grandmother, the people of Tianshui Village had to run into the river every day from then on, trying to wash away the disgusting smell.

"You have the wrong sense of time, and you have completely failed this experiment." Grandfather Guo Ma checked the dying Wang Hai and put the set of tools back together.

"In the process of growing, these plants go through different environments and times, so that a substance called spirit is born in their bodies. When you refine the pills, you need to study them carefully, so that you can not only increase the potency of the pills, but also increase the rate of becoming pills. Grandfather Guo Ma said.

Wang Hai was in a semi-coma and listened to Guo Ma's teachings.

He struggled to his feet, watching as Guo Ma expertly refined those plants into a pale golden pill.

One hundred days later, Wang Hai quietly left Tianshui Village. Before leaving, he sincerely took out a small wooden box and handed it to his grandfather Guo Ma.

It was a complete set of tools for refining pills, and in addition, there was a thick stack of animal skins, which were densely covered with words.

Originally, Guo Ma was too lazy to open those alchemy tools, he thought that all external forces were false and could make people die quickly.

But Guo Yang was very interested in these tools, and several times sneaked into his grandfather Guo Ma's room to look through the animal skins.

"Of all the offspring, you are the most unproductive, Guo Yang."

Grandfather Guo Ma's interests changed. Ever since the stone house had no roof, he would look up at that little piece of sky for a long time, day or night.

Guo Ma's room was once again filled with animal skins, but his job this time was simple: to record the small piece of celestial phenomena he observed every day.

Wind and clouds, thunder and lightning, as well as the changes of sunrise and sunset throughout the year, and so on.

Of all the information, the most detailed one is about the starry sky.

His grandfather, Guo Ma, insisted that Tianshui Village was like a grain of grain, floating in a long river of time, and no one could solve this situation.

"Those shining things in the starry sky are some other Tianshui villages, and we are all in the same river."

His grandfather, Guo Ma, discovered that all light is made up of particles that are invisible to the naked eye. Each grain of light contains a huge amount of energy, which is enough to change the problem of time difference caused by space.

Excited by this discovery, my grandfather sewed all the hides together, polished and repaired them, and then began to draw day and night.

He first drew the small piece of starry sky that he observed, and then, using the arithmetic he had learned from Wang Hai, he began to calculate and check step by step, and depicted the positions of the other stars on the animal skin in strict proportions and dimensions.

"If I can emit enough light, the other people in Tianshui Village who are studying the starry sky will also see me."

It took so much effort from his grandfather Guo Ma that he began to age rapidly and lost his eyes.
