Chapter 35 Solving the Hoe Soldiers

Zhang Xingcai's research work is mainly to make a few mirrors, which requires the chemical process of silver mirror reaction, which is Zhang Xingcai's strength, and it is also something that can make her blood boil.

The silver mirror reaction is very simple, it is the reaction of silver ammonia solution plus glucose in a heated state, this reaction Liu Hou learned in middle school, and he still remembers the principle.

The main raw materials used in this reaction are: glucose, ammonia, silver nitrate, sodium hydroxide.

Originally, there were no raw materials, but Zhang Xingcai came and had them, and as a chemical researcher, she brought various chemical agents. In the past few years, Zuo Ci has been tinkering with the three major acids of sulfuric acid, nitric acid, and hydrochloric acid, so is there still a problem with making silver nitrate?

There are also sodium hydroxide and calcium hydroxide, two major alkalis, which have been prepared long ago under Zuo Ci's tireless efforts to calcine various stones in recent years.

The glucose problem is indeed a problem. If you want to make glucose, Liu Hou really has no rut, but he doesn't have a rut in nature. The main ingredient of honey is glucose, and the soldiers were asked to dig out a few honeycombs to use it.

It's just that the purity is not high and it's a bit of a headache, if it can't be purified, I don't know if it will affect the effect of the silver mirror's reaction, but this Liu Hou doesn't care, although he gives it to Zhang Xingcai to do the real yàn, if she solves all the problems, then her real yàn will become completely undifficult, and she will lose the fun.

The biggest problem is the problem of ammonia, which is a solution of ammonia that dissolves in water. Liu Hou came up with the method of making ammonia: adding acid or alkali to urea and then heating it, which will release ammonia and carbon dioxide. That's true, but where does urea come from? At this time, there is no condition to synthesize urea, so you can only use natural ones.

Of course, the easiest way to get hold of natural urea is to extract it from urine. It's really hard to ask a little girl to tinker with and pee. Fortunately, Zhang Xingcai came with several graduate students in chemistry, and Zhang Xingcai unceremoniously caught them and handed over the preparation of ammonia to them.

As a result, all the raw materials for the silver mirror reaction were quickly settled, and the real process of making mirrors could be officially launched.

Zhang Xingcai first made several real glasses with glass, and only after success did he officially plate the mirror surface of those precious crystals. In fact, under Liu Hou's special attention, the glass industry has produced transparent glass after so many years of research, but the transparency is not very high, and it cannot meet the requirements of making optical materials.

However, there is no problem with these glasses being used for windows, as glassware, and as practical equipment. Zhang Xingcai's hands and feet are nimble, and in just two days, a few pieces of crystal are plated on the mirror, and the back of the mirror is brushed with paint, so that the mirror is not so easy to fall off and has the effect of anti-oxidation.

Finally, two small crystal mirrors were set diagonally in the two elbows of the copper tube at a certain angle, and a primitive periscope was thus created.

What the special forces company commander is holding in his hand now is the periscope that Zhang Xingcai has worked hard to conjure up in the past two days. Because of the use of high-quality crystal as a material, the light transmittance is particularly good, so the company commander can still clearly observe the surrounding situation under the dim light of the fire.

The black copper pipe elbow was only an inch long protruding from the ground, and it did not attract the attention of the Dongwu hoe soldiers on the night shift at all. Soon, the black elbow went around in circles, and the company commander also completed 360-degree environmental reconnaissance.

The periscope was withdrawn, and an engineer stepped forward in time to cover the hole with a black cloth to prevent the light from leaking to the ground. The company commander took out a piece of paper and lit a torch to write and draw on it. Soon, he wrote down the reconnaissance on paper and began to make battle plans.

In just a quarter of an hour, the battle plan was ready, and the company commander re-copied it, and asked a herald to quickly report to the headquarters and ask if he could do it.

After doing this, the company commander gathered his subordinates in a relatively open place in the tunnel, explained the battle plan to the soldiers, and assigned the combat tasks of each group.

The herald ran very fast, and after the company commander explained the battle plan and assigned the task, he brought back the command command. Liu Hou and Guo Youzhi studied the company commander's battle plan, thought it was feasible, and approved the company commander's battle plan, but let them not act for the time being and wait for an opportunity.

This timing will be given to the hot air balloon scouts, who speculate that a group of patrolmen will soon pass about a hundred paces from the place of action, based on the route and change of guard patterns of the Wu patrols in the east of the city. A hundred steps is not close, but it is not too far, and if they hear any noise, it will be a bad thing to come here to investigate.

In order to ensure that the plan was foolproof, the command ordered the special forces to wait for the arrival of the hot air balloon signal before they could act. Another quarter of an hour passed, and the hour was coming to an end, and this was the time when people were most sleepy and least vigilant, and a group of Soochow patrols passed by about a hundred paces from the "thin skin" as scheduled.

Since bonfires were lit everywhere in the city, and one of the patrolmen carried torches for every two people, the hot air balloon in the air soon spotted a patrol group passing about a hundred paces from the "thin skin".

The hot air balloon pilot notified the ground of the situation by light, and the command headquarters that received this information immediately issued an order to start the operation, and the herald flew out of the headquarters, drilled into the tunnel, ran all the way to the operation site, and conveyed the order to the company commander.

After receiving the order, the company commander immediately signaled the start of the operation, and all the special combat personnel took their positions and prepared to start the attack. First of all, five team members stepped forward to support the wooden planks with "thin skin" on top, and several engineers came up and unloaded the wooden stakes with three strikes and five divisions.

From now on, five special forces took the place of the stakes, supporting the planks and the "thin skin", while they also controlled the opening and closing of the tunnel entrance. Ten engineers stepped forward, inserted sharp blades along the edges of the planks, and began to cut the "thin skin".

Ten engineers worked together, each of whom was responsible for cutting a short section, and in just a few minutes, the "thin skin" on the board was separated from the surrounding ground. In this way, a one-foot square tunnel was opened.

And now, this tunnel entrance is still covered by a lid, which is the wooden board and the "thin skin" on it. Now the lid is held by five special forces, as long as they lift it hard, the special forces who have been prepared for a long time will swarm out of the tunnel mouth and kill in all directions.

However, in fact, there are two battle plans formulated by the company commander, and the one I just mentioned is Plan B, if the hoe soldiers on night duty discover the abnormal movement in the process of cutting the "thin skin" to open the tunnel crossing, this plan B will be implemented to attack the hoe soldiers.

The other plan, Plan A, was used undetected, and it was a sneak attack plan. A qiē depends on the situation on the ground. The company commander once again stretched out the periscope from the small hole and made a 360-degree observation, and the water on the ground was still flying and the river was flying, which met the conditions for the implementation of Plan A.

The company commander pulled his eyes out of the periscope and looked at the other team members, all of whom were staring at him, waiting for his command. The company commander stretched out his left hand, put his thumb up, and shook it a few times in front of everyone.

This is the agreed code, the meaning of the first set of plans, if it is the second set of plans, the index finger and the middle finger will be stretched out. Of course, they are all ancients, they don't know English, and of course they don't know what to say about Plan A or Plan B. So they are referred to by the first set and the first set of plans.

All the team members nodded their heads when they saw this thumb up, indicating that they understood. The special forces team members in front also gave their thumbs up and shook the team members behind them, because the team members standing behind were likely to not see the company commander's gestures, and they had to rely on this method of passing the orders layer by layer to the entire team.

Then, the company commander ordered two more team members, bent their index fingers and middle fingers, imitated the way they walked on two feet, walked quickly forward in the air, and then opened the palm of their right hand, palms down, pulled in front of their necks, and made a throat-cutting motion. The two team members nodded in understanding.

The company commander ordered four more team members, picked up a horse crossbow, made an aiming motion, and made a crouching motion with his hands. The four team members also nodded their heads in understanding. The company commander made a gesture to indicate that the operation would begin immediately.

First of all, the two team members who were ordered by the company commander to move first, they slowly lifted the lid on one side, gently climbed out of the tunnel entrance, and crawled towards the hoe soldiers. Yes, they move very quickly, but silently, and they move close to the ground, swimming on the ground like a spirit snake.

They are all black, and even their faces are painted with black charcoal, which can easily be mistaken for a shadow of something if you don't look closely in the dark night. The hoe soldier on the night shift was already drowsy, and his head was not facing this side, unaware that two shadows were rapidly approaching him.

The four members of the team who were ordered behind the company commander leaned half of their bodies out of the tunnel and lay on the edge of the tunnel, each holding a crossbow to the hoe soldiers who were staggering around the fire in the distance. Their mission is to snipe them down in time if a hoe striker spots them.

The first sound was a special soldier covering the hoe's mouth with his hand, and the hoe soldier was startled by the sudden attack and let out an exclamation, but unfortunately he was covered in his mouth and could only make a muffled sound. The second sound was the sound of special forces slitting his throat and blood gushing out of the carotid artery.

Another special soldier also painted a scoop on a gourd, slitting the throat of a sleeping hoe soldier. The two cut one to death, and found the other, and soon fifteen hoe soldiers went silently to meet the king of Yama.

The two special forces who were responsible for cutting their throats were obviously masters in the team, and they cut the throats of more than a dozen sleeping hoe soldiers in an instant, and the movements were extremely fast, without making any noise in the process, and none of the hoe soldiers were awakened in the whole process. After they killed all the hoe soldiers, they made a gesture towards the tunnel entrance. This gesture is to connect the thumb and forefinger in a circle, and the remaining three fingers are stretched out and erected.

This gesture means "好, 一qiē顺lì, success", and they don't know anything about how this gesture came about. However, the company commander knew that most of the gestures used by the special forces were formulated by His Royal Highness the Crown Prince himself, but even he didn't know that this gesture actually meant "ok".

The four snipers who were lying at the exit of the tunnel also made an "OK" gesture to the bottom of the tunnel, and then they jumped up and quickly ran around the entrance of the tunnel, and the four of them were lined up in all directions, kneeling on the ground on one leg and pointing in all directions with their crossbows.
