After the two sighed, the mercury over there was also refined, the cinnabar was decomposed by heat, the mercury metal had a large proportion, and it fell into the water below, when Wang Rucheng went to operate, Yang Wenli reminded again: "Rucheng, mercury is highly toxic, it should not be touched by hand, carefully dial it out with chopsticks, use a glass test cup to serve, and weigh it with a balance scale to prepare for the next experiment." ”

Wang Rucheng did as he was told, and weighed 52 grams of mercury, and he sang to Yang Wenli: "Great commander, get 52 grams of mercury." ”

Some time ago, since Yang Wenli produced the international standard rice, he led Wang Rucheng to develop a complete set of standard measuring instruments, including weights as small as one gram used in balance scales.

"Ru Cheng, the next experiment is very dangerous, you first weigh out ten grams of mercury to experiment, don't use it all, so that even if it explodes, the power will be much less, and it is also convenient to calculate the proportion of ingredients when making a large number of them in the future."

After Wang Rucheng did as he said, he hurriedly asked, "Great Commander, what should I do next?" ”

"The next step is to add nitric acid and alcohol, of which alcohol is the neutralizer, but I don't know the ratio, so you can only weigh everything, gram by gram, and you have to experiment again and again to come up with the best blend.

Stir carefully with a glass rod until you get white granular crystals, which are the mercury rayate crystals we want, which are very explosive, so you have to be careful and careful, and handle them gently. ”

This step, because it is necessary to test the proportion, to weigh gram by gram, repeated experiments, a lot of trouble, and Wang Rucheng was warned in advance, but also carefully added and stirred, so it took twice as long as the previous experiment to finally produce thundermercury.

It seems to be very troublesome, but in fact, he is already very lucky, the person who really invented thundermercury in history has been bombed a lot, it is precisely because of the experience of his predecessors, with Yang Wenli's guidance and reminders, so he can be safe.

Yang Wenli asked Wang Rucheng to take a crystal and gently try it with a hammer, and sure enough, it exploded as soon as he stepped on it, and the sound of "horn" scared Wang Rucheng a lot, and the commander really didn't lie to him, these things that looked ordinary were very dangerous.

"Commander, I know these three things, one is called propellant nitrocellulose, the other is called safety explosive, and the other is called detonating charge mercury thunderate, so how do we use it? And how do you make a bomb? Wang Rucheng was completely obsessed with scientific research, and after he tried it, he couldn't wait to ask again.

"Don't worry, with these three treasures, it's easy to make bombs, but now the question is how to make them in large quantities? And how to transport and preserve it safely, such as nitrocellulose as a propellant, in fact, it is also explosives, the difference is that explosives must be strictly sealed, but as a propellant can not be sealed, for example, thundermercury and safety explosives must not be stored together, nor can they be transported together to make bombs, and thundermercury must also be loaded before launching, otherwise it is very easy to blow up itself.

Thundermercury is generally a few grams of a few grams, wrapped in oiled paper, made into a rod, as a detonator, even if it explodes, the power is not great, will not kill people, but safety explosives, generally to be used in large quantities, an explosion will kill and injure, which forces us to pay great attention to safety.

And nitrocellulose is best packed with silk bags by pack, one pack is how much range, and how much is two packs? This requires us to experiment with post-production cannons, and officially quantify how much is a pack of propellants? Yang Wenli taught patiently.

"Silk? Commander, silk is very expensive, can't it be wrapped in paper or something? Wang Rucheng asked heartbrokenly.

"No, only the silk has no impurities after burning, which is beneficial to the gun chamber, and you can also omit the effort of cleaning the gun chamber a few times.

What are you afraid of silk? There are a lot of high-ranking officials and nobles in the Tartars, and we will grab a batch of them when the time comes. ”

"Hahahaha! Yeah! We got the cannon, so we're going to grab it. Wang Rucheng laughed and clapped his hands in agreement.

……

It's the middle of December in the blink of an eye, but there is no sign of the New Year on Changsheng Island, and it is full of busyness, even in the busy farming season.

Because it is just melting snow to cast the ice wall, the freshly melted snow water, poured into the wall mold will be instantly solidified, so the wall mold is also very simple, just use a wooden board to block it temporarily, and do not need to spend a lot of time, the project progress is very fast, it is simply a day, more than 10,000 slaves, a day can cast several miles of ice wall, according to this speed, this year can be completed.

Li Huaixuan stood in a depression and pointed to the opening of the depression and said to a few traitor scholars around him: "Leave a two-meter-wide opening here, and cast another ice wall half a meter in front of the opening, so that the Tartars can only enter the mouth from the side. ”

"Yes, the minions obey." Several traitor scholars hurriedly bent down to answer the order.

Now Li Huaixuan and each of them have five traitor scholar assistants, and they themselves only need to give orders, and they have really become people, and these traitor scholars are responsible for the work of engineering construction technology.

These openings are actually the doors of death, and when the Tartars enter these hollows, they will be hit by the black armor army above, and they can't climb and can't climb up, so they can only be beaten and can't fight back, and there is really no life or death.

"Eat" ...... "eat"......

Some Han women ran to various construction sites and shouted loudly to eat, they used to be servants in the families of Tartars or traitors, and they did not do evil, so they were lucky to be sentenced to be civilians, and they will be married to meritorious slave soldiers who have not yet started a family in the future, this is an executive order, there is no talk of free love, the only advantage is that because of their civilian status, they can be big women, not concubines.

These Han women are in charge of the easier cooking work, and they eat better when they are close to the water.

The Black Armor Army had already harvested a large amount of wild rice, bought a large amount of grain from Songjiang, conquered Fuzhou and Yongning, and several forts, Changsheng Island is not short of food now, even the slaves can be full, but the food is a little different, each slave only has a fried fragrant sea fish and a bowl of milky white fragrant kelp bone broth, no meat, no vegetables.

In this cold winter, vegetables are very valuable, only a small amount of storage is in the cellars of large families in the city, and the same is true for meat, all from the capture, only the soldiers who are guarding it can eat, and kelp is specially required by Yang Wenli in the past to collect a large amount of reserves, living by the sea, kelp is more than weeds, so it can be supplied in large quantities.

Those slaves who used to be Aha finally ate and were full when they arrived on Eternal Life Island, so they were full of enthusiasm and did not need to be whipped by the overseer at all, so the progress of the project was so fast.

This is what makes the Black Armor Army different from others, the Black Armor Army guarantees that everyone under its rule can be fed, whether it is a slave or a civilian, this is the case in Dabie Mountain, and the same is true in Liaodong.

"Dazhu, is it delicious?"

"It's delicious! This bone kelp soup is so exciting! ”

A few Aha squatted together, filled a bowl full of rice with a sea bowl, soaked in kelp bone broth, and shivered! Gulping down the rice in his mouth, from time to time he took a bite of the fragrant fried fish, his face was filled with a satisfied look, and an Aha asked his companion strangely, and the Aha called the pillar was not hypocritical, and he replied while eating a big mouthful.

They are just lowly Ahabs, with a low status, and their requirements are very simple, as long as they can eat well, it is enough! And those bannermen masters, ladies, young masters, and young ladies, after brutal suppression and whipping, have a strong temper, and have gone to the old slaves to report, and those who remain are already submissive people, and the difficulty of detention has been greatly reduced.
