When a group of Murongs are ready to deal with the enemies on both sides of the east and west.

Liu Yu, who was far away in the Central Plains, has already begun to calmly arrange new border defense strategies.

Especially after the workshop in Luoyang successfully made glass.

Liu Yu immediately asked the generals from the Yunzhong area of ​​Jiuyuan, Xiazhou to return to Luoyang.

He is planning to set up glass workshops in both places.

This decision surprised the generals Wu Xin, Liu Yan and others who returned to Luoyang.

They all did not understand Liu Yu's decision.

"Your Majesty, Xiazhou is a border." Wu Xin reminded.

"Of course, I know." Liu Yu said.

"Your Majesty, it's close to the Qiang and Hu tribes, and sometimes there are some bandits. It's not safe to see the glass workshop there." Liu Yan said.

"Of course I know what you said." Liu Yu said.

"Then why does Your Majesty still set up a workshop in Xiazhou?" Wu Xin was puzzled.

"Because I want to use a glass workshop to solve the military ration problem in Xiazhou!" Liu Yu said.

"Military ration issue? Your Majesty, this glass cannot be eaten." Liu Yan said.

Liu Yu gave him a look of contempt, "You guys are really stupid. I use the glass workshop to deal with military rations, not to eat glass."

"Your Majesty, is it necessary to use glass to do business and let the merchants in Guanzhong exchange grain for glass?" Wu Xin asked.

His strategy is indeed as Wu Xin said.

A glass workshop was set up in Xiazhou to make glass, and then the merchants in Guanzhong exchanged grain for glass.

In this way, the seller has the advantage. As long as the exchange price is appropriate, a continuous stream of grain will be transported to Xiazhou every year.

The merchants spontaneously transported food and grass, which eliminated the possible corruption and loss in the middle.

Moreover, this profitable business can also ensure the sustainability of Xiazhou military rations.

Huge profits are enough to break the law at the risk of beheading.

What's more, the profits of glass in the future will definitely be super huge, and Liu Yu doesn't believe that those businessmen will not be moved.

"However, Your Majesty has a lot of wasteland in Xiazhou. As long as you develop more military farms, you can ensure sufficient military rations. Why is it so troublesome?" Wu Xin was still a little puzzled.

"No, Xiazhou is located on the edge of the grassland. Although it can be cultivated, it greatly damages the ground force. Over time, it will cause a large area of ​​desert. It is necessary to maintain some military garrisons, but large-scale pioneering of land farms will not be worth the cost in the long run!" Liu Yu said.

At this time, Xiazhou was located in the famous Mu Us Desert area in later generations.

The Mu Us Desert is a thing that has turned from a grassland forest into a desert due to human factors.

The efforts of several generations, coupled with the role of high technology in later generations, turned the desert back into an oasis.

The itinerary for this Mu Us Desert started from the Qiang and Hu tribes.

A large number of military settlements have completely begun to desertify here.

If Liu Yu wants to stay in Xiazhou for a long time, he must be careful of desert dialects.

Therefore, setting up a workshop in Xiazhou, using sufficient local sand and soda ash to make glass, and then supplying grain and grass from the Central Plains of Guanzhong is the wisest strategy.

After listening to Liu Yu's explanation, Liu Yan, Wu Xin and others were all impressed.

"Your Majesty's vision is so great that you can think about what will happen hundreds of years later." Liu Yan said.

"Your Majesty, once this Xiazhou glass workshop opens, it may revitalize the entire northwest situation." Wu Xin said happily.

The number of people needed to make glass using craftsmen can be far less than the number of people who cultivate.

In remote Xiazhou, only a thousand craftsmen could support tens of thousands of soldiers.

If one thousand farmers could not support tens of thousands of soldiers no matter how they were. Once Liu Yu's method was released, it basically ensured that there would be no shortage of food and grass in Xiazhou.

At this time, Ge Hong, the supervisor of the workshop next to him, continued.

"Your Majesty, according to your instructions, we not only made glass, but also made glass mirrors!" Ge Hong said.

"What, really?" Liu Yu looked surprised.

He didn't expect that Ge Hong was so powerful.

"Really Your Majesty!" Ge Hong looked proud.

Then, Ge Hong took out a small box from a locked small room.

Judging from his cautious appearance, it seems to be a priceless treasure.

"Glass mirror? What is that?" Liu Yan said in confusion.

"It should be a mirror made of glass." Wu Xin was also puzzled.

All of them thought it was just a mirror, which should be similar to a bronze mirror.

After the bronze mirror is smooth, it is what women love the most.

However, when Ge Hong opened the small box and took out a glass mirror, everyone was so surprised that they almost dropped their chin.

"This, this,,,,," Liu Yan couldn't even speak.

"Why is it so clear?" Wu Xin also trembled all over.

The rest of the people were all staring wide.

They had never seen a mirror so clear.

Everything in the mirror is as clear as another real world.

Any bronze mirror I have seen before cannot be compared with this glass mirror.

"The glass mirror is done well." Liu Yu also nodded and praised.

With glass, glass mirrors can naturally be created.

"Are you a mercury mirror?" Liu Yu asked again.

Ge Hong nodded, "Yes, Your Majesty, as you ordered, this is the covered mercury!"
Chapter completed!
