"Two bitterness, three bitterness. This name should be your nickname. I'll give you two a single dragon and a single tiger. ”

Zheng Sheng can't change his hobby of naming people. Similarly, Li Anjian and Li Anjian's fellow villager Li Tianxiong, Li Tianxiong was also renamed Li Tianxiong by Zheng Sheng.

"Our name should be magnificent!" Zheng Sheng said.

"You're taking someone?" Wang Ru asked, seeing Zheng Sheng give an affirmative answer, "You really need to have some henchmen." ”

So she found the housekeeper: "Go to the village to see how many of each family meet Sheng'er's requirements, and send them all!" ”

Zheng Sheng blinked, Wang Ruzhen found him a group of little slaves!

However, what he wants to cultivate is an elite! His future backbone, mathematicians, scientists, and the like, are selected from among the slaves?

All right! Slaves also have merit, at least loyalty, isn't it? What's more, aren't the people under him, except for a few, all of them now be slaves?

Zheng Sheng was relieved.

In the afternoon, Zheng Wen hurried over, and he brought a white powder: "But this thing? ”

Zheng Sheng immediately started the experiment, took a basin of water, put a small amount of powder in it, and waited for a while, but the water surface did not change. Zheng Sheng stirred the wooden stick twice, but there was still no response.

Put some more in, and the same goes for it. Zheng Sheng threw them all into it, and the powder melted into the water. Zheng Sheng reached in and felt that the temperature had not changed.

"It's not saltpeter." Zheng Sheng said to Zheng Wen.

"Isn't it?" Zheng Wen was puzzled, "But this is saltpeter!" ”

"Then this is not saltpeter that can make ice." Zheng Shengdao.

Zheng Wen left in a huff.

Zheng Sheng felt that the Jin people had confused saltpeter, which could make ice, with something similar to it. Zheng Sheng didn't have any chemical instruments in his hand, and he couldn't tell what this thing was.

The failure of ice making did not discourage Zheng Sheng, because the monthly exchange time had come again.

Zheng Sheng and Zheng Wen have already discussed, and the paper produced by Nanxiang Paper Mill will be supplied to Zheng Sheng first. Zheng Wen also asked Zheng Sheng to "make" a larger piece of paper, preferably the same size as the paper they used. Zheng Sheng agreed.

But Zheng Sheng still doesn't know how much paper he can exchange at a time. He was afraid that if he put too much Jin paper, he would crush the balance and exchange less, and Zheng Sheng was unwilling.

Then, Zheng Sheng thought that the last time he exchanged it, he put the exchanged things first. It suddenly dawned on him that he knew what to do.

Zheng Sheng went to see his paper mountain again, the nine-cubic-meter hill was still in place, and even accumulated a lot of dust. Zheng Sheng cleaned up again.

July 14. In the dream, Zheng Sheng began to experiment again.

He said silently to the scale: "I want paper of the same quality as A4 and the same size as Jin paper, and its quantity is: the maximum amount of this paper that can be exchanged without damaging the balance." ”

A large stack of pure white paper appeared on the tray on the left side of the scale, which was consistent with what Zheng Sheng said!

Zheng Sheng laughed, this is the correct way to use the scale!

Required: 32,605 pieces of paper.

Zheng Sheng: Marvel!

He thought of that mountain of paper, how many pieces of paper should there be? It must be much more than 30,000.

Zheng Sheng silently recited, 32,605 pieces of paper in that paper mountain.

Zheng Sheng was given a large stack of new papers. This time it's a lot.

He began to wonder, what is the extreme value of redeeming these papers? Is it volume? Or the weight?

The volume is very small, and Zheng Sheng's estimate is less than 0.1 cubic meter. Even if it is exchanged for exchange materials, it is less than one cubic meter, which is really a little small.

As for the weight, Zheng Sheng couldn't carry the paper anymore, and the new paper was stacked in a corner of the original paper mountain, about half a meter high. Zheng Sheng picked up some of them, felt them, and estimated that the total weight of these papers was about 100 catties. That is, the maximum mass of the exchange material should be around two hundred and fifty to three hundred kilograms.

If this is really the value, Zheng Sheng feels that the balance exchange is still very reliable, but if it is less than a cubic meter of volume, this is a bit of a pit!

Zheng Sheng looked at this large stack of papers, and a strange thought appeared in his heart: if someone kept staring at these Jin papers at night, how would it come out?

Zheng Sheng suddenly had an urgent thought in his heart, he needed a confined space to be used as an exchange point! You can't just redeem it like this anymore.

In this world, there are still many smart people, and once someone tries to find out what his secret method is, the possibility of him revealing his stuff will greatly increase!

Now he is not eye-catching, and after returning to the other hospital, he will have to deal with this matter well, and it is not too late to make amends.

Zheng Sheng silently estimated that there were more than 6,000 pieces of new paper.

At present, Zheng Wen's publicity work for the new paper is still in urgent planning.

There is no hurry to sell paper, but once it is really promoted, this paper will definitely be in short supply. Even if he comes to exchange new paper for three days a month, he will get less than 20,000 pieces, which will definitely not meet the market demand.

Therefore, the new paper can only be bought and sold in the mode of hunger marketing.

In addition, the consumption of oil is not very much, and Zheng Sheng does not need to spend too many times to exchange for sesame oil.

Zheng Wen told him that the Zheng family was already squeezing the cooking oil specially used for stir-frying, which might not taste as good as Zheng Sheng's exchange oil, but it was much better than the oil used to light the lamp.

Of course, Wancheng's drunken incense residence still has to use Zheng Sheng's exchange oil. After all, it's used to make a name for yourself. Regardless of the difference with other stir-fried dishes, why is Zuixiangju so expensive?

There was also the filter paper, and Zheng Sheng decided to try to see if he could exchange it for a new filter tool.

Mrs. Wang found Zheng Sheng: "Sheng'er, you got the kind of stone that can make ice, right?" ”

Zheng Shenggang wanted to say no, but he suddenly had a new idea, "Well, my cousin only found a little bit, so he went to find a new one." ”

"We've run out of ice." Wang Ru stared at Zheng Sheng: "When will you make the ice?" ”

"Early tomorrow morning. But first, I'm going to go to the ice cellar. ”

"You're going to the ice cellar?" Wang Ru asked, "Okay, I'll take you!" ”

Zheng Sheng had no choice but to let Wang Ru take him over. But he's been to the ice cellar many times, okay?

Zheng Sheng followed Wang Ru to the courtyard near the mountain at the westernmost end of the manor, she and Zheng Sheng entered the house, walked up the stairs down, and soon came to a stone gate, Wang Zhong led people to open the heavy stone door. A cool smell came over the face.

Wang Ru let out a sigh: "In summer, the ice cellar is the coolest!" ”

Zheng Sheng "......" and he knew that Wang Ru definitely didn't come specifically to accompany him.

Wang Zhong said: "Madam, prince, the ice cellar is cold, let's go out quickly!" ”

Zheng Sheng looked around, the area of his ice cellar was actually not very large, the length and width were about six or seven meters, and the height was only a little more than two meters. Of course, not all ice cellars can be stored. His family's ice is stored in large vats. Zheng Sheng clearly remembered that there were a total of twenty-four vats here.

In addition to the thick stone walls and stone walls that are insulated, these extra-thick vats are also very well insulated.

Zheng Sheng checked them one by one and found that except for a small amount of ice in one tank, the other tanks were empty.
