After listening to Li Jing's words, Hou Junji sneered: "I'm afraid Li Xiang's statement is a bit conservative, and this official seems that even this kind of consumption on the battlefield is enough." ”

Li Jing looked at Hou Junji and said: "Lord Hou is right, the requirement of my dragoon army is that the sons and daughters should be as close to the actual battle as possible in the battle. ”

After listening to Li Jing's words, Li Shimin couldn't help frowning slightly.

Hou Junji sneered and said, "Isn't Li Xiangmo crazy? Didn't the fighters hurt each other so much during training that they all had a private enmity? ”

Li Zhi interjected: "Lord Hou is also a famous general, how can he not know that only life and death can form a deep friendship?" ”

Hou Junji's original purpose was to target Li Zhi, and when he saw him speak at this time, he naturally wanted to take advantage of it.

So he opened his mouth and said to Li Zhi: "Your Highness is young and doesn't know about military affairs, but you don't know that there are dragons and snakes in the army, and soldiers from all over the country are all factions, how can they easily make friends with others?" ”

Li Zhi said: "Lord Hou does not dare to agree with this, the difference between regions cannot be diluted, as long as the method is appropriate, this matter is easy." ”

Hou Junji said: "Your Highness's words are taken for granted, even if the soldiers have a grudge in front of the commander, they will not easily show it, Your Highness is afraid that he has been deceived by them." ”

Li Zhi said: "Lord Hou said that he laughed, there is a mentor in the army who always pays attention to it, if there is an abnormality, how can he hide it from his eyes?" ”

Hou Junji saw Li Zhi carrying Li Jing out, and immediately stopped talking.

He knew that his ability to lead troops was much worse than Li Jing's, and if he continued to dwell on this topic at this time, he would inevitably suffer.

He changed the topic and said to Li Zhi: "Even if His Highness has a good plan to solve the contradictions in the army, why should the soldiers suffer more damage? ”

Li Zhi said: "This king thinks that it is much better to be injured in training than to die on the battlefield. ”

Hou Junji said: "The form of the battlefield is changing rapidly, and no matter how hard the soldiers train, there will inevitably be deaths and injuries. ”

Li Zhidao: "What Lord Hou said is certainly reasonable, but the combat goal of the Dragoon Army is like this, otherwise why spend so much money and food in vain? ”

Hou Junji saw that he couldn't say anything about Li Zhi, so he turned his head and said to Li Shimin: "Your Majesty, the minister thinks that His Royal Highness the King of Jin's requirements for the dragoon army are unreasonable, please ask Your Majesty to make a holy judgment." ”

He decisively threw the burden to Li Shimin.

The meaning is obvious, anyway, I don't think it's appropriate to train the army like this, you are the boss, you have the final say.

To be honest, Li Shimin himself is a little unsure.

Although he has never been defeated on the battlefield, he has never been so ruthless in training.

Now listening to Li Zhi's meaning, it seems that he wants to make the dragoons fully feel the cruelty on the battlefield during training, which is actually difficult to do in his opinion.

However, he saw that Li Jing and Li Zhi both seemed to be quite confident in this, and he couldn't help but be a little curious.

I thought: Could it be that they have found some unique way?

Thinking of this, he coughed lightly and said, "Since the medicine master and the pheasant slave are quite confident in this, it is better to continue." ”

After saying this, he looked at Hou Junji again and said, "Hou Aiqing doesn't have to be too anxious, you can wait a year before seeing the real chapter." ”

After listening to Li Shimin's words, Hou Junji could only nod helplessly.

Li Zhi and Li Jing did not change their approach because of this incident.

As winter approached, the boiler was finally built and installed.

Li Zhi repeatedly told Empress Changsun to let her often take Li Lizhi and Princess Chengyang to the swimming pool to exercise.

He never forgot the health problems of the eldest grandson, which is why he strongly advocated the establishment of a medical school.

In addition to being busy installing the boilers, Li Zhi also equipped the dragoons with more sophisticated personal equipment.

These include a down winter coat, a pair of leather boots, and a quilt.

There are also climbing claws, daggers, and a backpack.

Li Zhi made all the cotton produced in the experimental fields into military uniforms, so that the soldiers' clothes were much more wearable.

The division of labor between Li Zhi and Li Jing is very clear.

Li Zhi was responsible for proposing ideas and researching equipment, while Li Jing was responsible for training soldiers and teaching battle formations.

In order to increase the reconnaissance ability of the soldiers, Li Zhi began to find ways to burn glass and prepare it for use in making telescopes.

Now Liu An has long been accustomed to Li Zhi smelting things from time to time.

Even he himself sometimes smelts some ore to study.

For these, Li Zhi not only did not stop it, but sometimes even took the initiative to point out from the side.

He compiled some of the simple physics and chemistry knowledge he knew into two books, and handed them directly to Liu An for him to use as enlightenment reading.

Minerals such as quartz and fluorite are never lacking here in Li Zhi.

Because he will always ask Liu An to reserve in the name of research.

Now their cauldrons have been upgraded several times, and even the materials are divided into several types.

At this time, they used ceramic crucibles.

Inside smelted is quartz, fluorite, quicklime and white feldspar.

It is also mixed with some plant ash solution to replace lye.

Soon a pot of completely boiled solution was completed, and Li Zhi immediately poured some of the solution into a special mold.

These molds have also been made a long time ago, mainly some planes, circles and utensils and so on.

The main purpose of doing this is to allow the various solutions of the experiment to be condensed and formed to facilitate the subsequent analysis and research.

When the liquid in the mold cooled, Li Zhi carefully opened the molds one by one.

What appears in front of you is a piece of exquisite glass products.

Li Zhi picked up a glass bowl and admired it carefully.

This bowl is not crystal clear and white, and the color is slightly dark blue.

However, in Li Zhi's opinion, this is completely acceptable, after all, glass has never appeared on the market.

Liu An was also admiring a glass on the side.

He couldn't help but sigh while looking at the cup: "Your Highness, this thing is so crystal clear, if you sell it for money, it will definitely sell for a lot of money." ”

Li Zhi said to Liu An with a smile: "It seems that you have been in contact with Shopkeeper Pei for a long time, and you have also learned a lot of business experience!" ”

Liu An scratched his scalp in embarrassment and said, "The slave has only learned some fur, and it is far from being compared to His Royal Highness and Shopkeeper Pei." ”

Li Zhi said: "Since this is the case, then you should practice more, this material this king decided to call it glass, you can use it to develop some novel goods and give it to the shopkeeper Pei to sell." ”

After listening to Li Zhi's words, Liu An said happily: "Your Highness appreciates the slave." ”

Li Zhi smiled and did not speak.

At present, glass is made, but it is not the ideal material to make a telescope.

Li Zhi also needed to add some other oxides to it, and the crucible used also needed to be replaced with a platinum crucible.

Most of these things are available here, but most of them are by-products obtained from other experiments, so they need to be purified.

In the next few days, Li Zhi and Liu An were busy separately.

Li Zhi was in charge of purifying the raw materials, while Liu An was busy designing molds and handing over some glass products to Pei Mingli for sale.
