The Wizard Academy and the Knight Academy will be established in the future. Such large academys need sufficient money to support and also have a sufficient population base. Otherwise, you can't even recruit a few students, so what else can this Wizard Academy run?

In fact, the chance of witch awakening is still very low. Usually, the chance of witch awakening is around one in ten thousand to three in ten thousand.

According to the population ratio of this world, it takes about 50,000 or 60,000 people to have a chance of witch awakening, so in this world, witches are actually a scarce resource.

Su Ming hated the Eternal Fire Church's behavior of hunting witches.

......

The two witches of the Northern Secret Dharma Assembly quickly accepted the task. Their mission was not only to improve wild sweet cane, but also to improve wheat, corn, and soybeans. In this era, seed yield was limited per mu. Even if the land was fertile, a mu of farmland would produce at most 400 kilograms of wheat. Soybeans were even smaller, and a mu of land was only two or three hundred kilograms. Corn was slightly better, and it looked like six hundred kilograms.

If you want to make grain high yield, in addition to fertilizer, you are constantly improving seeds. After generations of selection and cultivation, you can cultivate high yield seeds. This practice is complicated, cumbersome and good things have passed. The two witches thought about it for a while and agreed.

When the witches were improving the good varieties, Su Ming had already purchased sweet cane from merchants. Although the cost was relatively high, if sugar could be produced, the cost was nothing at all.

The yield of sweet cane in the south is still very high and the price is not expensive. The main reason is that this thing does not require too good land to grow.

The first batch of sweet cane was delivered quickly. Su Ming asked someone to send it directly to the factory for juice extraction. The factory's juicer uses hydraulic power, which has fast juice extraction speed and high efficiency. The peeled sugar cane is sent to the machine. With a crackling sound, a slightly turbid liquid slowly flows out at the opening of the machine.

After these sugar cane juices are filtered by charcoal, the sugar water has become very clear. At this time, it is boiled. When boiling sugar cane juice, you need to control the heat. Once the heat is high, the sugar may be boiled and pasted in the end.

To make sweet cane juice, you need to evaporate three-quarters of the water inside. When only one-quarter of the sweet cane juice is left, stop the fire and let the sugar cane juice cool naturally. When the temperature drops, white crystals will precipitate, and those crystals are white sugar.

If the filtration is not done or the filtration technology fails, after the final boiling, it will be brown sugar or brown sugar. This sugar is a little bitter, but the price is also not cheap.

Soon, according to Su Ming's method, the first pot of sugar water in the factory was almost boiled. Two craftsmen lifted the iron pot and put it next to it to let it cool naturally.

After waiting for about half an hour, the sweet cane juice water cooled down and some white crystals appeared at the bottom of the pot. After the sweet cane juice was completely cooled, and after no more crystals appeared, take out the sucrose, so that the sugar was obtained.

As for the remaining sugarcane juice, it also needs to be kept. Although this sugarcane juice cannot precipitate sugar, it can be used to make rum.

Rum tastes pretty good and is very popular in the south. The northern region prefers spirits, while the southern region prefers rum or wine.

In addition to these, the residue left after the sweet cane was squeezed into sugar was not discarded, but was sent to the papermaking workshop by Su Ming. The sugar cane bagasse was squeezed and broken and must be crushed. It can be thrown directly into a pool for reaction.

It can be said that a sweet cane has been used to the limit by Su Ming.

After the first batch of sugar was made, Su Ming asked someone to weigh it and made a total of 80 kilograms of sugar. This time, a total of 1,000 kilograms of sweet sugar were prepared. The sugar yield rate was about 8%, and the amount of sugar yield was already very good.

"The sugarcane contains quite high sugar content." After checking, Su Ming nodded and said.

The sugar content of sweet cane is about 10%. In addition to the loss, you can finally obtain eighty or ninety kilograms of white sugar. The amount of sugar produced in this is considered good, and the sugar content of sweet cane needs to reach more than 10%.

Of course, the sugar yield rate of these sweet canes cannot be compared with previous lives. The sugar content of sugar canes in the previous lives can reach 15% and 18% after being cultivated. Moreover, the technology used is more advanced, and white sugar can be precipitated as much as possible.

Su Ming reached out and pinched a piece of sugar and put it in his mouth. A sweet feeling instantly filled his mouth. The sucrose tasted very positive, without the strange smell of stone honey.

This time, the caravan transported a total of ten tons of sugar cane. After all, Su Ming obtained more than 800 kilograms of sugar. Su Ming was not worried about the sales of sugar. As long as the news was released, the merchants and nobles would come immediately.

Su Ming left 300 kilograms of sugar for 800 kilograms, and the remaining 500 kilograms of sugar were sold to five merchants. Su Ming divided half of the sugar for 300 kilograms of sugar and sent it to Jennifer, Kana City. The remaining part Su Ming was divided into several parts again, one part for Anne, one part for him, and the last part was distributed to other witches and knights, even the witches of the Northland Secret Dharma Assembly.

Another 500 kilograms of sugar Su Ming was used for sale. After seeing so much sugar, several merchants looked surprised and excited. In their impression, sugar was not easy to deal with. The sugar produced in this era was actually not real sugar. But after the brown sugar condensed, a white frost would appear on the surface. The workers scraped off the layer of white frost, which was called white sugar, also called frost sugar.

The sugar produced in this way is more expensive than snow salt. In this way, if you want to get one pound of sugar, you need to scrape hundreds of pounds of brown sugar. Before that, the annual output of southern sugar was only a few dozen pounds.

In fact, sugar is a completely luxury item, which is a delicacy that only nobles and big businessmen can enjoy. After seeing that the weight of sugar is 100 kilograms, everyone was excited and almost jumped up.

Due to the continuous output of snow salt during this period, the price has dropped slightly, but this level is not too obvious. Now with sugar, Milanheim's financial resources will definitely be increased again.

Su Ming ordered the price of sugar at 80 gold coins per catty, but even so, these sugars were purchased at the first time.

If you want to continue producing sugar, you can only continue to buy sweet cane. However, it will take some time for the sweet cane to be transported here.
