Everyone left after the meeting, they all had their own things to do, Li Yan and Li Xin didn't leave, they were not responsible for specific things, the main task was to study, such as abacus.

In this era, there are already abacus, and abacus also has it, but Datang's abacus has not yet become a complete abacus for later generations, and Datang's abacus formula is only a simple addition, subtraction, multiplication and division, and Li Ke took out a complete abacus formula that has been counted by modern statistics, it is no exaggeration to say that this set of formulas alone can make Datang's mathematical calculation speed improve by hundreds of years.

It is a huge blessing for the mathematical problems used in various places such as calculating costs, computational engineering, etc.

In fact, ancient mathematics is not bad in some aspects, but there are not so many formulas and theorems, and it is not so complete, and the mathematics of later generations is summarized by countless scientists.

These mathematical theorems alone shine with one glorious name after another, but in these ancient mathematical techniques, some theorems have preliminary models, but most of them have not yet been summarized.

At night, Li Ke entered the space in his mind again, and he basically came in once every night to take a look, not for anything else, but to see when those fogs would be able to unlock the new warehouse.

During this time, there are two new warehouses to be unlocked, and one of the warehouses has actually been unlocked almost completely, but because the entrance happens to be outside the range that has been unlocked, Li Ke is a little helpless and can only wait for its entrance to be unlocked.

The other warehouse has just been unlocked, but the warehouse door is on his side.

Because the distribution range of the warehouses is different, and the fog is unlocked in all directions with the office building as the center, or the location where Li Ke crossed at the beginning, which leads to the different types of unlocking of these warehouses.

At night, when Li Ke entered the warehouse, his spirit was immediately shocked, I go, today is good news, the doors of the two warehouses are all unlocked, but one warehouse is only partially unlocked, and the other warehouse is completely unlocked.

Li Ke ran directly to the fully unlocked warehouse first, and it was not difficult to enter the gate of the warehouse, but before entering the warehouse gate, Li Ke began to pray to the gods and goddesses indiscriminately: "Seeds!" Seed! Seed! ”

After praying for a minute, Li Ke jerked his leg up and walked in.

When Li Ke entered the warehouse, he went straight to the name plate hanging at the door of the warehouse, which had relevant records of stored materials.

But when Li Ke saw the above record, he was completely speechless, this thing ...... It's a surprise and it's not a surprise.

Li Ke felt that unlocking things in these warehouses was like opening a blind box, and you didn't know what was inside until you opened it. Because Li Ke had no right to know the data of these warehouses before, he didn't know what was stored in them.

The only thing he was sure of was that the strategic warehouse he was in was definitely not for the storage of industrial and military strategic materials, and as for the underground part, Li Ke suspected that it was the standard configuration of every strategic warehouse.

Inside this warehouse is a very important strategic reserve - sugar!

That's right, it's sugar, it's all in the huge warehouse, and the total storage in this huge warehouse is 100,000 tons! Compared with the country's frequent purchase of hundreds of thousands of tons of white sugar for separation, 100,000 tons is nothing.

It's just that...... 100,000 tons, if it is the seeds stored by the state, then Li Ke will be able to complete the optimization and restructuring of grain in an instant.

But this thing is sugar...... How to put it, for any country, white sugar is an extremely important strategic reserve.

During World War II, Pepsi was able to exchange sugar water for a whole fleet of former Damao, and the grain and meat of the foot basin chicken in World War II rose no more than 20 times, but sugar could rise more than 300 times.

Many people think that sugar is just a condiment, but in fact it is a life-saving thing, in the case of a lack of energy in the human body, tons and tons of a bottle of sugar water can make a person live for several more days.

More importantly, sugar has applications in all industrial and biological fields, and how wide is the scope of application? It can be said that in all the fields that a modern person can think of in the future, there is sugar!

Sucrose has three times the calories of rice, it doesn't need to be processed, and it's extremely shelf-stable, with the sugar theoretically infinite in a culture that remains extremely dry.

In the absence of medicine, even sprinkling sugar on the wound can avoid bacterial infection and stop bleeding, and sugar is also one of the important raw materials in the military industry.

cough, in order not to let Xiao Ri have a judgment, to put it simply, it is one of the raw materials for making "boom", multiply the sugar in a grenade with a range of ten kilometers dozens of times, and it can be turned into a rocket, well, a single finger of range.

So, don't play around by yourself, at least three years to start, there is no cap, so sugar-coated cannonballs have a certain theoretical basis, not simply symbolic, otherwise why not call them rotten cannonballs.

So these 100,000 tons of white sugar ...... It's a surprise and it's not a surprise.

The surprise is because Li Ke may have the opportunity to play the "boom" and "boom" games one day, not because he is surprised, but he can only eat it now. I found some of it in the canteen before, but I never expected that there would be 100,000 tons here.

After reading the sugar, Li Ke turned around and left here and went to the second warehouse.

When he entered the second warehouse and checked the records, Li Ke was stunned again...... It's the same as white sugar, it feels pleasantly surprised and not pleasantly surprised.

This warehouse is actually the seed bank that Li Ke has in mind!

I am not surprised that the seeds stored here are not grain seeds, but the seeds of other important crops, and the surprise is that the seeds in this are useful to Li Ke!

Because only a part of the warehouse has been unlocked now, Li Ke has to go inside to know which part of the seeds have been unlocked, but these seeds are useful to Li Ke no matter what they are.

Entering the storage area at the back, Li Ke quickly found the seeds stored in the unlocked part, and only two of the five seeds stored in this warehouse were unlocked.

One is rubber.

That's right, Li Ke unlocked the rubber tree seed, but this thing, it takes at least five years to grow into a rubber tree. But in fact, rubber is really not a necessary thing for Li Ke, because there are actually substitutes for rubber in China, Eucommia ulmoides rubber, although the characteristics of the two are different, each has its own advantages and disadvantages, but it can also replace each other.

Eucommia gum and rubber have a similar effect, Li Ke originally wanted to let people start planting and developing the use of eucommia gum, but he never expected to get rubber seeds out. It's a sweet annoyance.

But even if this thing is available now, it is estimated that Li Ke will have to spend time to develop it, which is estimated to be more than ten years Don't think about it, rubber is not so easy to do, even the use of natural rubber materials is not so easy, it seems that latex is simpler, sell latex pillow mattresses first? Li Ke felt that he had to flip through the books when he went back.

The second seed is a plant that Li Ke can use right now - alfalfa.
