"At least in terms of cost, it is estimated that it is a hundred times higher than directly burning glass to make a telescope. At the same time, such a large telescope is not easy to find," Su Shuang added.

"You can consider smaller ones, such as making binoculars..." Liu Tao thought about it and suggested. After all, unless astronomical telescopes or something in later generations, most of them are mainly binoculars, and I don't know if it is for this consideration.

"This is also the case, which can slightly increase the output of the telescope!" Su Shuang immediately replied excitedly when he heard this. If it was a binocular, then there was no need to be that big. Such natural crystals are also easier to find.

"Then let's create a batch of such telescopes first to ensure that all generals have at least one or two such telescopes." Liu Tao immediately ordered that, not to mention the cost, it is important to increase the scope of investigation.

In the future, if conditions apply, each scout must be equipped with one, so that you can walk fewer roads and see things farther.

If the path you take is shorter, the speed of message transmission will also be improved. In this era, time is the lifeline!

The Ministry of Rites has nothing to do, at most it is some rituals to sacrifice to heaven. When the emperor was plowing in spring, he would also bring all officials to the fields to farm as a manifestation of farming.

Enke starts the exam in the fall, and there is still half a year left before the exam begins.

Then Zhu Yan still said the same thing, and needed to expand the army. Liu Tao nodded to show that he understood. After Xia Cheng, he began to expand the army. At the same time, he asked Xun Yu whether it was possible to expand the army by about 25,000 yuan.

"If the food harvested in summer reaches the predetermined value, then there is no problem." Xun Yu said out of the list. The number of 25,000 happened to be stuck at his preset safety point.

By chance, or... I looked at Guo Jia inadvertently, and the latter looked exactly like a slightest... Yes, it was just this guy who leaked his secrets. He really was careless about making friends, why don’t he just break up?

"Is the food in Jizhou safely transported?" Liu Tao asked afterwards. He said he wanted to buy food last year. Later, Yuan Shao checked it strictly, so he planned to use the winter to transport it secretly.

That is, it started in the middle of last month, and it should be transported no matter what the time is. It was just a coincidence that Liu Tao just remembered something.

For transportation safety, Liu Tao used several lucky scrolls in those days. At that time, it was really lucky. After a treasure went around dozens of turns, it actually came to his hands...

Four-leaf clover, lucky value +10. This is the name of the treasure, a very ordinary four-leaf clover, but it will never wither. Even so, it is generally inconspicuous.

The most unlikely treasure in theory fell into his hands like this. Liu Tao even doubted that it didn't seem strange to find a lucky golden horseshoe with +20.

"It has been safely put into the warehouse, and the quality of the grain is also very good." Xun Yu replied. There is one thing he did not tell Guo Jia, just the amount of this batch of grain. It was beyond expectations that this thing was not included in the plan at the beginning.

Unexpectedly, the transportation was smoothly. With this, it is not a big problem to expand the enrollment of 40,000 yuan strictly speaking.

He is not as good as Guo Jia in strategy, but Guo Jia is still young in terms of being petty...
