"What's wrong with these?" Duan Yunfei saw Li Xueyan's movements and asked.

Li Xueyan took the pieces of paper in her hand, rubbed them casually, and saw obvious cracks on the paper, and the fibers on the paper also came out. Li Xueyan explained: "See? This kind of paper is too fragile to be rubbed like this, let alone put on top of the pot to grill meat. ”

Duan Yunfei took a closer look, indeed, these pieces of paper are a little thicker than rice paper, and they are good for writing, but if they are used for barbecue, they are far from enough.

Li Xueyan took a good look at the paper in her hand again, in addition to the ones she picked out, there were about fifteen of them. Li Xueyan sorted out the paper and finally got up.

"Let's go, let's see if the paper works."

When the house was just built, Li Xueyan asked people to help move the things that couldn't fit in the house in the town, including the barbecue table and pots.

Li Xueyan first cut out a small piece of each piece of paper and pasted it on a notebook in order, one page at a time.

Then light a charcoal fire and put it in the hole on the table, and then put the baking pot on it, and Li Xueyan began to evaluate it one by one. In order to ensure that the difference between the laughter of the fire is as small as possible, Li Xueyan always pays attention to the degree of charcoal burning to avoid obtaining data with large errors.

In addition, Li Xueyan also took a handful of incense to time, in order to see which paper can last the longest on the same roasting pot and the same charcoal fire, and then recorded the data in the notebook with paper blocks.

Duan Yunfei was very impressed when he looked at it from the side, he thought that Li Xueyan would just measure it simply, but he didn't expect her to be so meticulous. It seems that Li Xueyan is just very arrogant in life, and she will never be negligent in treating such details.

Fifteen pieces of paper were placed on the baking pot one by one, and Li Xueyan also put some of the same ingredients on it to bake in order to know the service life of the paper more accurately. Of course, after these ingredients were baked, she didn't eat them.

After all the paper was measured, Li Xueyan did not throw away the paper directly, but carefully packed the used paper, took a small notebook and went out with Duan Yunfei.

Duan Yunfei was curious: "What are we going out for?" Haven't they all been measured? ”

Among the fifteen pieces of paper, only four of them seem to be usable at present, and when they are roasted by fire underneath and the ingredients are placed on top, there is no breaking or burning, which Li Xueyan still admires the people of this era.

She didn't have much hope, but it turned out to be such a big surprise for her.

But it's too early to be happy, and she has to go for the final assessment.

Li Xueyan flew to the river with Duan Yun and said to Duan Yunfei, "Let's catch fish." ”

Duan Yunfei looked puzzled, "Catch fish? Grab it by hand? You want to add food and go directly to buy fish......" Duan Yunfei didn't understand why Li Xueyan suddenly asked him to catch fish, and didn't say it in advance, now he doesn't have any tools, how can he catch it?

Li Xueyan obviously didn't intend to give Duan Yunfei a chance to struggle, and said directly: "At least eight, fish fry will do." Of course, I don't mind how many there are, so go for it. ”

Duan Yunfei glanced at the papers in Li Xueyan's hand, and then corresponded to the number of fish fry she needed, and probably understood what she wanted to do.

Fortunately, there are not no people who make a living from fishing in this area, Duan Yunfei went to inquire, and explained that his purpose was really not to steal business with them, so someone finally helped him.

Of course, the most important thing is that Duan Yunfei offered to be paid.

Soon, with the help of others, Duan Yunfei caught a bunch of fish fry, and the man kindly gave them a few large bowls to hold the fish.

Li Xueyan first filled each bowl with three fish fry of about the same size, then crumpled the four pieces of used paper she brought over into a ball and threw them into the bowl to observe the reaction of the fish.

There were two bowls of fish that died a moment after the paper ball was thrown in, and two bowls of fish that seemed to be fine. Just in case, Li Xueyan fished out all the fish and the paper balls, and the water in the bowl was not poured, and two more fish were put in each bowl again.

After a while, the fish in the two bowls where the fish had died died earlier, and the fish in the remaining two bowls were still fine.

Li Xueyan took out her notebook and recorded it again. In the end, there are only two kinds of paper left that can be of good quality.

On the way back, Li Xueyan sighed: "If you don't test this, you won't know if you will eat the dead when the time comes." It's scary to think about. ”

Duan Yunfei was a little ashamed, he really hadn't thought of this before, "But how did you come up with the idea of using fish to test toxicity?" ”

Li Xueyan glanced at Duan Yunfei and said as a matter of course: "If you use mice or cockroaches to measure, I'm afraid you won't want to catch them." ”

Duan Yunfei: "...... That's disgusting indeed. ”

Forget about catching fish, if Li Xueyan really asked him to catch mice and cockroaches, Duan Yunfei didn't dare to imagine how he would react.

Li Xueyan felt funny when she saw Duan Yunfei's expression of eating flies, and explained: "The main reason is that the vitality of the fish fry is relatively fragile, if the paper is not toxic and even the fry can't be eaten, then it means that people will definitely be fine if they eat it." Cockroaches are different, if people eat and die, they don't necessarily die. ”

Duan Yunfei was amused by Li Xueyan's statement, "How do you know that cockroaches can't die if they eat, have you tried it?" ”

Li Xueyan shook her head, "It's not true, it's disgusting." But don't they all say that Xiaoqiang can't be killed, since he can't die, then he must not be able to die, right? ”

"Xiaoqiang? Is Xiaoqiang a cockroach? ”

Li Xueyan nodded, "Cute, right?" ”

Duan Yunfei: "......" If you think it's cute, it's cute.

They didn't go home directly, but went to the place where Duan Yunfei took the paper. When he introduced Duan Yunfei's paper, he said that his name was Cai Bai, and when he heard this name, Li Xueyan didn't know where to complain for a while.

Cai Bai...... Why don't you call it cabbage the other way around? And it's so coincidental that his surname is Cai, and his craftsmanship is so good, could he be Cai Lun's descendant?

After Cai Bai finished introducing himself, he found that Li Xueyan seemed to be distracted, not knowing what he was thinking, Cai Bai smiled and said, "What does Boss Li think?" You can't be thinking of my name, are you? ”

Li Xueyan reacted and smiled embarrassedly, "I didn't ......" complained in my heart that other people's names had been debunked or something, it was too embarrassing.

Cai Bai smiled indifferently, "It's okay, many people call me cabbage directly, or old cabbage, I'm used to it." ”

Li Xueyan said embarrassedly: "Where is it, Bai Lao, oh no, Boss Cai." ”

Cai Bai glanced at Li Xueyan meaningfully.

Li Xueyan was even more embarrassed.

Fortunately, Duan Yunfei was very powerful at this time, and directly diverted the topic, "Boss Cai, we came to see your paper, I took it back today, and there are two kinds of things that can be used." If the price is right, our paper will be taken from you in the future. ”

Hearing that there was something to use, Cai Bai was a little out of the way, "Oh? Anything else that can be used? Which two? ”

Li Xueyan: "......" co-authored that you just gave us a pile of paper from you, and you didn't even see if it could be used, right?

Thinking so in her heart, Li Xueyan's movements in her hands were not delayed at all, and she hurriedly took out the notebook she used to record, and in the end, the two that did not poison the fish were marked by her and put two big checks.

The notebook was handed over to Cai Bai's hand, and he could see at a glance which of the two kinds of paper they were, and he was not surprised at all, "Are they really these two?" ”

Duan Yunfei asked, "I don't know what the price of these two is?" ”

"Wait a minute." After Cai Bai finished speaking, he turned around and went into the house, and soon came out, holding two pieces of paper in his hand, and handed them to them. "Let's see if it's two?"

Li Xueyan took it, looked at it carefully, smelled it again from the surface to the feel, and then carefully compared it with the two pieces of paper pasted on her notebook, and nodded, "That's right." ”

Cai Bai said: "This one, I got it when I went elsewhere before, I don't know what they used it for, I think I might be able to use it in the future, so I brought a little back, but I didn't expect it to be really used this time." Cai Bai pointed to one of the two pieces of paper and said.

Li Xueyan asked, "Does it mean that this kind of paper was not made by you here?" So there's no way to provide it to us? ”

Cai Bai nodded, "That's it." ”

"What about this?" Li Xueyan picked up another one and looked at it carefully.

In fact, at the end of the evaluation, the remaining two pieces of paper looked similar in mechanics and appearance, whether it was the material or the method, at that time Li Xueyan almost thought that it was the same kind of paper and someone accidentally gave two copies. Just in case, Li Xueyan still tested both, and the results were really two different papers.

Cai Bai smiled: "This kind of ah, I studied the kind and made it myself." If you need it, I can provide it to you for a long time. ”

Li Xueyan and Duan Yunfei glanced at each other, and they both saw a satisfied smile in each other's eyes.

Cai Bai said again: "But I have to say it first, this kind of paper is much more troublesome to make than others, so the price is ......."

"Don't worry about the price, we'll decide on this."

Cai Bai was stunned for a moment, and then smiled again, "You girl, aren't you afraid that I will ask for a price?" ”

Li Xueyan smiled: "You won't." ”

"Since you said no, then it won't. You're a funny girl, so that's it? ”

"Okay."

Now that the paper problem was solved, Li Xueyan went to the blacksmith and carpenter again, and it was already time to start work. The original barbecue restaurant only sold the grilled meat, and the store was not very large.

If you sell charcoal barbecue directly in the original barbecue restaurant, there is a good chance that the location will not be enough. So Li Xueyan decided to buy a larger storefront, she had a hunch that this business would definitely be hotter than every previous time.

With such a hunch, Li Xueyan is full of motivation no matter what she does, and her actions are faster than before. In addition, Li Xueyan made a generous move, and quickly finalized a densely populated place in the town and bought a store that was about to be opened.

When the owner of the shop signed the title deed with her, he complained that it was a bustling place, but in fact, no one wanted to patronize it. In his tone, he was still secretly glad that he had finally sold, and someone had come to him to buy it before, but he probably knew that his business here was not very good, so the price he gave was not very high, so he never sold it.

Li Xueyan listened to the shopkeeper's complaints and didn't say a word. If your business is not good, you will blame the location for having problems, and in the place with the most people, things can't be sold, so it can only prove that his things are really bad, or the price is too expensive, so no one will buy them.
