"Report." The lieutenant ran over as fast as he could.

"Your Excellency, your Excellency. The shells were two miles away. The lieutenant saluted on one knee.

"Good. Good. Ju Xin shouted happily.

"That's right. How about this musket? Ju Xin asked again.

"Back to my lord, this barrel is really difficult to imitate." Gong Cheng said embarrassedly.

"Stupid. Intensify imitation. Be quick. It's done. There are many rewards. If it doesn't work. Watch your head. Ji Xin said fiercely.

"This artillery should be cast as soon as possible, and the larger the caliber, the better." Ji Xin said with a different face.

"Yes, yes, let's do it for the small ones." Gong Cheng immediately agreed.

Ju Xin simply ignored it. Report the good news directly to King Yan.

At the same time that Yan Guo was preparing to copy a large number of Qin State artillery, Li Mu was not idle.

Li Mu had already learned the power of this firearm on the battlefield. And the killing effect is very powerful. A person who has been shot often cannot be treated, that is, if he is shot. also entered the ghost gate with one foot.

What Li Mu could do was to avoid the killing front of the firearm. Attack from the flanks. In the event that the enemy does not react, quickly approach the enemy. Then take advantage of the fact that muskets and artillery are not good at close combat, and quickly control the situation.

To achieve such a result, it is necessary to train a completely new cavalry team. Since Cloudsdale a farewell. Li Mu had already begun to pay close attention to the stirrups, horseshoes and other things that appeared in the cavalry of the Qin State. And began to imitate a large number of them.

And cavalry tactics, because of the solid effect of the stirrups, began to appear a completely new tactic, that is. Take advantage of the cavalry's rapid mobility to quickly circle the enemy's rear and attack from the rear. And not only to launch mounted archery as in the past. The effect of the dash is affected by the lack of stirrups. Now, thanks to the stirrups, the armament has been greatly improved.

From melee swords to spears and halberds for massive killings. The Zhao army's combat weapons are rapidly escalating.

While Li Mu was busy with the deployment of troops, he was also very concerned about the situation of weapons and equipment. The Zhao army was different from the Qin army, which had an extremely developed weapon-making workshop, which was now upgraded to an arsenal, while the Zhao army did not have these at all. The craftsmen were all temporarily recruited from the neighborhood. Manpower simply could not meet the combat needs of the Zhao army.

It took a few days to build 200 stirrups and horseshoes. Li Mu was very worried about these.

And those Zhao cavalry after being equipped with stirrups and seeing the benefits of this equipment with their own eyes, they spontaneously began to imitate them, and they used hemp rope and leather. Or cloth, made in the shape of stirrups. So. You can get the same effect as stirrups.

In this way, the cavalry units of the Zhao army began to make a large number of homemade stirrups. The number quickly expanded from two hundred to nearly seven thousand cavalry. It was in this difficult environment that Zhao Jun completed the rough weapon upgrade work.

Li Mu looked at this group of bloody men blankly, and was silent for a long time. The Zhao army was able to fight against the Qin army, relying on these soldiers with flesh and blood.

"Let's step up our training." Li Mu looked at the cavalry of the Zhao army who had been training overnight, and turned to leave. The guards around him also followed.

Li Mu returned to the big tent and marked the collected military information of the Yan army on the sand table, as before, the Yan army did not have much movement. Despite this, Li Mu still did not take it lightly. Opposite. Instead, Li Mu sent a large number of scouts to reconnoiter the information of the Yan army's reinforcements.

For Wu Sui, Fang Cheng side. Li Mu was even more cautious in conducting investigations. Pay special attention to this movement. Look at the distance on the graph. The distance between these two places is relatively far from the giant deer. It is the least likely to arouse Yan Jun's vigilance. But it was a cavalry force that could quickly tear a hole through the two places. Then go around to the rear of the Yan army. Directly hit the supply line of the Yan army in Julu City. Achieve the effect of a siege. This is Li Mu's idea. It is best to be able to lure the Yan army to take the initiative in the direction of the giant deer. Ambush it halfway through. Regarding such an arrangement, Li Mu believed that only by attacking the reinforcements from the Yan State would it be most likely to transfer out the Yan army of Julu. In this way, the Zhao army occupied the initiative, and the Yan army, which lost the initiative, could not effectively attack the Zhao army even if it had an absolute superiority in weapons.

The general guidelines have been finalized. Li Mu could only wait quietly and patiently.

A big war begins to brew in a quiet standoff. And Shangwen is also brewing his own things. It's just that what Shangwen is brewing is not war, but ethanol.

After several days of fermentation. Those grains that have been fermented can no longer be fermented.

There is fermented grain. Shangwen also needs a fractionation column. Shang Wen wanted ethanol with high purity, so that he could make an alcohol lamp for experiments. and alcohol blowtorches.

For fractionation columns, Shangwen cannot yet be manufactured industrially, but it can be made in the laboratory, and Shangwen uses clay pots. According to the principle of fractionation column, the clay pot type fractionation column is made. Shang Wen was full of praise for this invention. Originally, I planned to use glass, but the production of glass was too low. Even basic experiments are not guaranteed.

To this end, Shangwen spent a long time looking for a cheap, convenient and convenient equipment. Finally, Shang Wen finally found the clay pot.

In addition to the fractionation column. Shangwen also built a rectification unit, mainly to further upgrade to the rectification fractionation column. The purpose of this is to speed up ethanol purity.

With such equipment, Shangwen immediately began the extraction of ethanol from the rectification fractionation column.

In the limited space, increase the heat exchange area of the liquid phase mixture as much as possible, the mixture generally used for rectification fractionation is organic azeotrope, the azeotrope is first heated from the reactor to the fractionation section, and the low boiling point continues to rise, because the temperature of the top of the tower is consistent with the low boiling point after the heat transfer of the low boiling point, so the low boiling point is fractionated out, and the higher boiling point is not reached the corresponding boiling point, so it will be cooled and refluxed to the reaction kettle or the lower part of the fractionation column, and the low boiling point is completely distilled. The higher boiling point is successively fractionated, then the high boiling point is distilled, and finally the bottom of the reactor is the residue.

Coal stoves are used for heating equipment. Since the experiment was done at noon, the temperature was still very high. Shang Wen was sweating all over his body and doing experiments. Shang Wen is not, and some adjustments have to be made. The main problem is the condenser.

After an hour-long heated rectification fractionation process, a small glass of ethanol was finally extracted. The characteristic aroma of alcohol attracted an uninvited guest.

Old man Wei, this character who likes to drink two glasses when he has nothing to do. For the aroma of wine, he has long smelled the taste.
