With the increase in food prices and sugar prices in the past two weeks, Zhangjia Rice Brewing Store’s business has really been slack. Perhaps for the rich, there is no difference between a few copper plates and a few silver coins, but for many incomes As far as the bottom of the society is not high, when a slight price change is passed on to them, it becomes a huge pressure for survival. They are also more sensitive to prices. A bowl of rice brewed by Zhang's family, even if only a copper plate is added, But for some people, this copper plate represents a 20% price increase, which is difficult to accept.

Seeing the Chinese woman in front of him who dragged the drooling child away from the rice brewing shop, Zhang Tie could only smile helplessly. In the past, this little guy often came to eat. Now, with the price of rice brewing Rising, his mother had to be cruel and drag him away. For these small households, the increase in food prices will certainly not only affect the price of a bowl of rice brew, but the increase in the overall cost of living. When food prices are high, how can firewood, rice, oil and salt not increase with them? I heard that the price of coal in Heiyan City has also begun to increase in the past two days. The most obvious thing is that each car that sends briquettes has increased by five copper plates. The price of grain is rising, the price of coal is rising, and the steel produced by steel plants. Naturally, the price increase will follow. Although the current price increase is still very small, it does not bode well for many people.

The ugly modified tricycle from Zhang’s family was borrowed by a neighbor early this morning. They said they would buy some food. Several family members have already borrowed them in the past two days. They all borrowed them to drag things. Sister-in-law went to the hospital this morning. Sister-in-law said that she was a little uncomfortable. Mom became nervous. After getting up this morning, the two of them left. Then Zhang Tie was at home alone, looking at the rice brewing shop, and boringly chased flies with a fan in the shop.

Zhang Tieren was in the rice brewing shop, but he was a little absent-minded, because at this moment his whole mind was concentrated in his own mind. At this moment, some interesting things were happening in Zhang Tie's mind...

The changes brought about by the seven-fold increase in mental power are causing him to work hard for two weeks in "Pearl Mind and Fortune", which has undergone a radical change. Before yesterday, Zhang Tie had to visualize an abacus with three gears in his mind. It will take a long time. The visualized abacus is not stable. The speed of which abacus is used for mental arithmetic is not very fast. There is no convenient manual method. In short, it has not reached the point where it can be practical. But this situation is today. Changed completely in the morning.

At this moment, in Zhang Tie’s mind, a seven-gear golden abacus is hovering firmly in Zhang Tie’s sea of ​​knowledge. The counting beads on the abacus are automatically flipping up and down without a hand, outputting Calculate the values ​​one by one.

How much is 36 times 98...3528!

How much is 1269 plus 9621...10890!

How much 362 times 125 equals...45250!

How much is 639 divided by 12...53.25!

How much is 98564 divided by 125...788.512!

...

At the beginning, Zhang Tie needed to type the formulas to get the results. Later, when Zhang Tie saw the questions, his heart moved. Those formulas flashed in his heart. The abacus had already calculated the results, and then practiced. After a while, Zhang Tie discovered that he didn’t even need to recite the formula. Often when he saw the question, the result was already out. It was too fast. After two years of abacus, Zhang Tie finally discovered the Chinese. The power of this ancient computing tool, Zhang Tie doesn’t know where the book "Pearl Mind Arithmetic" which is recommended by elementary school students is written, but purely speaking of the strength and quality of mental power, Zhang Tie does not believe in this world. There is any elementary school student who is stronger than he is now. Perhaps his previous mental power is similar to that of a elementary school student, but now his mental power has reached seven times the original after incorporating the glorious fruit, which is too strong. A bit. And after using seven times the mental power to promote Zhu's mental calculation, the powerful side of Zhu's mental calculation began to be fully revealed. Any addition, subtraction, multiplication, and division within seven digits, Zhang Tie only took a look, as long as the problem reached his head, the result He just came out, and didn’t even hit a little bit in the middle. Not only that, Zhang Tie found that the abacus was easy to stabilize after visualization. In the process, he also sold a few bowls of rice noodles and made a few small businesses. It doesn't affect...

My current calculation speed should be faster than the hand-cranked metal calculators in those exchanges and trading houses! Zhang Tie was thinking about it, but he didn’t expect that the first benefit he would bring to himself after the seven-fold increase in mental power would be to make Zhu’s mind reach this level overnight. If he goes to the grocery store now, he must be Can surprise that fellow Don De.

Because the bead-minded arithmetic was so easy to use, it felt so amazing and fit, Zhang Tie unexpectedly came up with a very bold and even absurd idea-or, in the ages long before the abacus was invented, the abacus was originally That's how it is used. As long as you visualize it in your mind, people of that era have very powerful mental powers, so they can easily use this kind of calculation tool in their minds, but later people's mental powers don't know anything. After the reason has declined, it is no longer difficult to realize this kind of calculation in their heads. Only when someone made a real abacus and started to operate it by hand, and then at some point, I don’t know if it is hundreds or thousands of years. Later, when everyone was accustomed to operating the abacus with their hands, suddenly another guy had a flash of inspiration. He felt that this thing could be visualized in his mind, and operated with pure spirit and consciousness, so he invented the pearl heart. Divine calculation accidentally restored the true use of this calculation tool...

If this is the case, isn’t he the only person who truly masters this magical computing tool? I don’t know if this magical computing tool is likely to evolve to a higher level of ability, it looks like that guy from Tang De It has been said that in the magical East, there are some powerful professions. For example, the mysterious fortuneteller holds a more magical calculation tool called "Yi". That calculation tool calculates not numbers, but people’s good, bad, bad, and fortune. Will there be any relationship between the two and the evolution of the world?

Just as Zhang Tie was thinking wildly, his mother and sister-in-law came back. Zhang Tie quickly dismissed the abacus in the sea of ​​knowledge, and then rushed to ask with concern, "Mother, what's the matter with sister-in-law!"

As soon as he said the words, Zhang Tie realized that this question was a little silly, as if he was a little awkward, his sister-in-law's face was reddened, and his mother stared at Zhang Tie's head and said, "It's about you. Hurry up and cook..."

...

In the afternoon, as usual, Zhang Tie helped his mother make rice brew at home, and with his sister-in-law, the job was relatively easier. After lunch, the neighbor returned the borrowed tricycle. Zhang Tie went down and rode a tricycle to buy rice and sugar. Unsurprisingly, the prices of these two things went up a little bit because of the rice brewing business at home last week. Not very good. I only bought two bags of rice this time. When I got home, my mother was teaching my sister how to make yeast liquid.

"This yeast liquid is very important. Whether the final taste of the rice brew is good or not, it depends on it. Our Zhang's yeast is made by ourselves. These spare jars for yeast must be burned before use. Boil the boiled water, then shake it with the boiled water and cool it for later use. Generally, there are two cans at home, one is in use and the other is in fermentation. Just make one can and wait until it is almost used. Add water to it, put some chopped fruits, peels, pits and the like in it. Open the lid and shake it every day to let the inside ventilate. Usually about a week, a new can of yeast will be enough. It’s done. You need to put two spoonfuls of fermented yeast in each pot of rice stuffed before sealing. Come and taste a bit. These yeast solutions are delicious. Zhang Tie used to come to steal it..."

Zhang Tie has long been familiar with these contents, and he didn't care about it. Especially when his mother was still teaching her shortcomings, it made Zhang Tie lose face. I don’t know why. Today, I listened to my mother. With these things, Zhang Tie’s mind suddenly flashed a flash of lightning, and a thought suddenly appeared in Zhang Tie’s mind...

Yeast-rice stuffed-

Yeast after mutated evolution-rice brew after mutated evolution?

Zhang Tie remembers that there is a special option in the Black Iron Fort that can promote the mutation and evolution of all creatures. When I first entered the Black Iron Fort, I tried it and played with a sprouting potato in the pit. After receiving no results for a few days, Zhang Tie also forgot about the incident. Then today, while watching his mother teaching his sister how to make yeast solution, Zhang Tie suddenly had an idea-if he could The yeast used for making rice brew at home evolves or mutates to produce a brand-new yeast liquid. Will the made rice brew taste better? If this is the case, it can be regarded as opening a market for the rice brewing business at home.

Zhang Tie thought for a while, and the more he thought about it, the more he felt that this method should be feasible. At least he can try it. Zhang's family has used the old method to make rice brew for ten or twenty years. It doesn't matter if you try a new one. Even if you fail, you won't lose a few hairs!

Thinking of this, Zhang Tie got excited. Then in the evening, while his mother was not paying attention, he found a clean glass bottle in the kitchen, quietly filled a half bottle of yeast liquid and took it to his attic cabin. I quickly came to the Fortress of Black Iron, opened the "Microorganism" management panel of "Carbon-based Biology and Species Management" under "Biology and Species Management", and after selecting the bottle of yeast liquid, I invested 300 Aura values ​​at a time , 5 merit points and 0.1 basic energy reserve, began to try to carry out the first mutation and evolution process of yeast.
