There is nothing to say about the mortar shell, it is a jet-black bullet body, and you can't see anything with your eyes, but when Yang Wenli saw the latest mass-produced mortar, he found that he had forgotten a very important process, that is, the blue baking process in the later stage of weapons and equipment.

The surface of steel parts is blackened, and some are called bluing. This process is mainly to slow down the corrosion rate of iron, and the commonly used methods for blackening treatment are traditional alkaline heating blackening and late room temperature blackening, which is called roasting blue.

Of course, Yang Wenli can't know such a complex process, but he has his own unique antioxidant treatment process for metal surfaces, and the armor, shield, and Yang knife of the Black Armor Army all use this process, so it is called the Black Armor Army.

The surface antioxidant treatment process he created is better than the blue baking process invented by the West in the future, and the equipment of the Black Armor Army has been used for more than a year, without the slightest sign of rust, even the parts that have been scratched by knives and arrows in battle.

This is the essential difference between the two processes, the blue baking process, which is equivalent to a layer of high-quality anti-rust paint, the surface is scratched, and the anti-rust effect is naturally lost.

Yang Wenli's unique process is to carry out surface doping, doped with a certain amount of rare metals, deep into the inner layer, rather than floating on the surface, not only can prevent rust, but also significantly enhance the metal performance, scratching, must also stop at the surface, so it still does not affect its anti-rust effect.

In fact, to put it bluntly, it is a fire, which is simmered with white plaster mud water rich in rare metals, and the rare metals penetrate into the surface or interior of the metal.

"Ru Cheng, you still have one less process, you should know that the surface of steel and iron is easy to rust. This is because of the chemical reaction with oxygen atoms in the air, rust is ferric tetroxide, and hematite is actually a substance.

You know that the surface of our black armor army's weapons and equipment is black, because of the later fire-fire treatment, which is the surface doping, so that the surface of the steel parts infiltrates into rare metals, and the iron atoms in the steel undergo a cobonding reaction to generate a unique and very stable substance, so as to achieve the effect of anti-oxidation.

You also know the specific process, I won't say more, in the future, the parts of the mortar will have to be fired in the later stage, but you have to remember that you should not overheat, so as not to affect the performance of the steel parts, just a little red hot to fire. ”

Wang Rucheng was taken aback when he heard this, and he hurriedly thanked: "Thank you for the reminder from the Great Commander, my subordinates almost missed a big incident, and I will change it immediately." ”

Yang Wenli smiled and waved his hand and said, "What are you thanking me for, everyone is serving the Black Armor Army as a whole!" By the way, have you tried the performance of mortars? ”

In the past, because the mortar shell was not mass-produced, the experimental data obtained was very small, and it was impossible to count, and to really test the performance of the mortar, it was necessary to start from scratch, so as to obtain the maximum and minimum range of the mortar, and make the firing table data, so Yang Wenli had this question.

"We are conducting experiments and will soon begin teaching officers and soldiers of the Black Armor Army." Wang Rucheng replied immediately.

"Hmmm! Very good! I have nothing more to worry about. Mortars were temporarily produced 140 units, 20 units per small flag, including my Guards.

However, when conducting large-scale battles, it is necessary to use them intensively, and only when artillery is used intensively can it exert unimaginable power.

It is only used alone during normal training or when a small flag is engaged in a small campaign. ”

"Grand Commander, isn't it used by logistics baggage?" In the past, ballistas were carried and used by heavy soldiers, so Wang Rucheng asked.

"Nope! No! No! There are too many tasks for the logistical baggage troops, and this time the mortars were issued directly to every small flag.

The weight of the mortar is relatively light, so let the fighters overcome it! Yang Wenli shook his hand again and again and explained.

"Whoa! I know. ”

……

Time flew by, it was already the beginning of May, and there were only less than two months left for the Nuergandu Division, and the various units had strengthened the training of cavalry, and Wang Rucheng had also begun to lead people to train the combat troops in artillery training.

Now that there are two major killing weapons in hand, the Black Armor Army is no longer afraid that Jiannu will suddenly cross the sea to the island, they have absolute confidence that Jiannu will die as many as possible, and some people are even shouting to counterattack Jiannu.

This is not absurd, it is entirely possible to do it, but Yang Rentian and Yang Renyue, who are clear about Yang Wenli's overall strategy, stopped the initiative of their subordinates.

To put it bluntly, now is not the time for the Black Armor Army to show its talents, and Jiannu is also very useful for the time being, he is a good target and can attract the attention of the Ming Army.

Now Changsheng Island is on the mainland side, and only the troops who train cavalry are patrolling by the way, of course, there are also beacon smoke at each checkpoint, which can be ignited at any time.

Yes, the units have been fully transferred to cavalry training. Ordinary soldiers don't have as powerful divine sense as Yang Wenli, which requires time and more training.

Yang Wenli also took advantage of the opportunity to train riding skills, and took Xiao Yan'er, a follower, and dozens of slave soldiers to ride horses to various units for spot checks.

"Driving" "driving" ......

Yang Wenli and his entourage galloped on horseback, and the sound of horses' hooves rumbled, raising dust in the sky.

Because it was about to move to Nuergandusi, there was no grain cultivation on Changsheng Island this year, and the vast fields were the natural places for cavalry training.

Along the way, from time to time, you can see groups of soldiers training horsemanship, they are generally a group of six, training in groups, just the size of five slave soldiers of a regular soldier.

Everyone was not very skilled, and they could not train cavalry in large formations, so they could only disperse and train in small formations.

Every cavalry team they encountered on the way, seeing the iconic high spire of Yang Wenli's helmet and the thick red tassels, stopped their horses and saluted him to pay respect.

When he arrived near Yang Rentian's station, Yang Rentian, who was training riding outside, saw the arrival of the Great Commander and hurriedly rode his horse to meet him.

"Huh"......

Yang Wenli tightened the reins, and with a "whoo" in his mouth, he saw the Simba people standing up, neighing, and immediately stopped the galloping horses, and the slave soldiers who followed behind also stopped the galloping horses.

"Archon, ma'am,"

Yang Rentian immediately stepped on, beat his chest with his right hand and saluted them.

"Haha! Rentian, how are you doing in equestrian training? Can you go long distances? Yang Wenli asked him with a heroic laugh.

"Back to the Great Commander, his subordinates are blunt, and they can only run for a short distance, the time is too long, and the butt and thighs can't stand it." Yang Rentian replied honestly.

"Hahahaha! You have not mastered the essentials, when the horse is galloping, the ups and downs are very large, if you have been sitting on the horse's back, it will definitely turn your ass into two petals, you should stand on the horse's pedal when the horse's back falls, do not sit on the horse's back, you can avoid the pain of bumps.

As for the pain in the thighs, it is caused by the fact that you are still too nervous, and you use your thighs to hold the horse's back tightly and rub it, which can be avoided if you are proficient. Yang Wenli laughed and passed on his experience.
