"Where is this Oz Field?" I looked at the map again and again under the scorching sun to make sure that I was not in the wrong place, but as far as I could see, there were only a few wilted trees accompanying me, and I could not even see a bird.

The field of Osi is the legendary land of silk, I heard that there is a special silk here, which is extremely tough but extremely soft, not afraid of fire or rain, and will not be corroded for hundreds of years, and if you put this silk on the ground in the dark, it will emit a silver light, illuminating the path under the feet of the holder, and it is still very useful for people like me who often run out of electricity when they are away for a long time.

But legend by legend, I've been around here for almost a week, and I haven't gained anything.

"You're from outsider?" I was sitting at a roadside stall when a man next to me asked.

"Well, I'm traveling around and I'm walking around here. I replied, and the accent of the man in front of me was that of a local, "Well, you're a local, right? Do you know if there are any silkworm breeders around here?"

"Silkworm farming?" he looked at me suspiciously.

"Yes, silkworm farming. I'm looking for a place called Os's Field, but there's nothing on the map, and I wonder if there are silkworm farmers who should know. ”

"Here, here's the mung bean soup you ordered," the stall owner said, placing a large bowl in front of me, "Are you looking for that silk country?"

"Yes, yes, you know what?"

"Haha, where is the wilderness of Osi, it's all a story for children. The boss said, "Don't look at it, there are alfalfa growing in this neighborhood, where does the silk come from?" ”

"Well... Haha, yes, how can there be such a place. I smiled awkwardly and paid the boss for the mung bean soup.

"What do you think to believe that there really is such a mythical place?" asked me the man across from me after the boss left.

"I'm more interested in these things," I said, "maybe I'll find them." ”

"You've been out and about?" the man asked me, "backpacker?"

"Most of the time. "I drank half a bowl of mung bean soup in one go, and the heat in my whole body immediately decreased by more than half.

"I envy you guys who can travel around. He said, "I can only live on this land." ”

"Haha, I have my own reasons. I said, "Even if you travel, you still have to find some work to do, otherwise you won't have anything to eat, by the way, I have some gadgets here, do you like it?" I took out my little container.

"Where did you get all this?" the man pulled out an item in the container, "It looks good... Weird, what is this?"

"That's frog skin," I said, "there's a kind of frog that molts like a snake, and the skin it sheds can indicate the temperature." If you like it, sell it cheaply?"

“... I don't need that," he said, disgustingly putting the frog back in my container, "you don't usually make much money selling these." ”

"It's not my main job," I said, "I'm a ghostwriter, writing letters for people." ”

"Are there many people writing letters now?"

"It's okay, it's enough to make ends meet, after all, not everyone has a phone and an internet. I said, "In addition to humans, there are quite a few creatures who want to write letters." ”

The man looked at me with a look of disbelief on his face.

"Haha, just kidding, don't take it seriously. I smiled and continued to drink the mung bean soup.

"You—" The man looked at me for a long time, his expression was very serious, "Can you write a letter to a creature that is not human?"

"It's a joke," I said, "it's not a human creature, so it's better to have less contact." ”

"What if I said I knew how to find the Fields of Os?" said the man, looking at his expression not like a joke.

Seeing that I didn't speak, the man got up and paid the bill, "If you want to know, come to my house and have a look." ”

The man is not lying, and his home is indeed different.

"What is this?" I asked, pointing to a dozen or so two-meter-tall white objects in front of me.

"Cocoons. He replied, "Didn't you ask if there were any silkworm keepers?"

“... It's too big..."The thing in front of me is not an ordinary silkworm cocoon, "It's not a human thing, what's going on?"

"I don't know what's going on. The man invited me to sit on a chair, the room was empty, except for a bed and a table, there were only these huge cocoons, it seemed that he lived here alone, "I am a alfalfa grower, I don't earn much, but a person can be considered passable, I guess because I am too poor, my health is not good, so the eldest is not small and has not found a wife." ”

"Isn't in good health?" I asked, and the man in front of me was 1.8 meters tall, not strong, but not thin.

"I've been frail since I was a child, I can't do any physical work, I don't sleep well, and as the old saying goes, it's easy to press the bed. He waved his hand, "Don't talk about this, this in front of you... Cocoon, what do you think?"

"It's supposed to be a youkai," I said, "but don't worry, it's not a bad youkai, I guess there's some special reason for putting this thing with you." ”

"Youkai?" said the man, "and that should be true, three months ago one night, when I was asleep, a girl pushed open my door. He looked at the ground, "The girl is very beautiful, but she is dressed in clothes made of leaves, and she doesn't look like a girl in the world." At this, he blushed a little.

"And then?"

"She didn't say who she was, but gave me a handful of soil and a few seeds that didn't look special, and told me to plant them in the soil she had brought and water them once a day for fifteen days. He said, "When I came to my senses, and the girl was gone, I planted the seed as she had said, and soon it sprouted, and the leaves were of five colors, and had a pleasant fragrance." ”

"It's a five-colored grass," I said, "a kind of herb that only youkai have, and when eaten to strengthen the body, it can also be used to dye it." ”

On the fifteenth day the girl came again, and this time she did not say a word, but left a coloured moth and went away, and not long after she was gone the moth laid a dozen eggs, which the next morning had hatched into little silkworms. ”

"So this cocoon has something to do with those silkworms?" I said.

"Well, that's right," the man nodded, "and then the girl would appear in my room at the same time every night, and feed the silkworms with leaves of five colors, and soon the silkworms grew as big as the palm of a man's hand, and after a month of careful care of the girl, the silkworms began to spin silk, and finally left these huge cocoons, but the girl never came." ”

"You're... I'm in love with this girl. I looked at him, not knowing what to say, "It doesn't belong to humans, you won't have results." ”

"I know," said the man, "such a beautiful girl, I dare not be delusional, but wonder why she did this, and then I asked a lot of people, and I learned that the place of Osino must have come from there." ”
