Yang Hongru had no objection at all to the arrangement of becoming the commander of the grain and grass transportation team. He wished he could train his soldiers for a while longer, and it would be irresponsible for the new recruits to go to the battlefield hastily.

While the veterans are still there, there is no need for them, the fledglings, to take the lead. When it is their turn to take the lead, it means that this war has entered a white-hot stage.

Yang Hongru felt that his men should be the most elite grain and grass escort team in the Northern Wei Dynasty - with so many troops in the Northern Wei Dynasty, he had never seen heavy armored cavalry escorting grain and grass!

The general has nothing to do when facing this situation. In the world military system, the weapons of the soldiers who join the army are their own property. You can't help Yang Hongru being rich! How rich is the great witch priest of the Mulan clan? You can't even think about it.

!

So after the army set off, Yang Hongru and his friends were far behind the large army. They only needed to keep an eye on the food and grass, and everything would be fine. The workload was not big at all.

When Yang Hongru received the vehicle loaded with grain and grass, his head was buzzing.

This... what kind of crappy car is it?

The axle and the wheel are one piece? It’s going to kill me! It’s so hard to turn this crappy car around!

Yang Hongru went to the quartermaster with a pained face and asked: "This car...doesn't it have bearings?"

"What kind of bearing? This is what a transport truck looks like!" the quartermaster asked in confusion.

Well! In this backward era, bearings have not yet appeared, and the two wheels can only rotate synchronously. As for the problem of excessive friction, it can only be lubricated with animal grease.

No wonder the grain transport troops moved so slowly. Such a broken vehicle would be heavy to death if two horses pulled it together.

It's time to show the wisdom of the time traveler! If he didn't improve this broken car, Yang Hongru would have no time to train soldiers, and all his good time every day would be wasted on transportation.

Think about the carriages of later generations. A thin old horse can easily pull a thousand kilograms of weight very easily. But today's carriages can carry a few hundred kilograms and are extremely heavy. The difference lies in the bearings.

Rolling bearings can infinitely reduce friction and greatly improve the carriage's loading capacity.

This is the truth, but it was really difficult for the craftsmen of the Northern Wei Dynasty to make qualified bearings. Apart from other things, where did the steel balls that meet the specifications come from? In fact, the invention of rolling bearings was less than three hundred years ago.

.Sliding bearings are many years early.

But now there is a person who doesn't talk about science, but only talks about supernatural powers - he can use the mediation of nature to directly turn iron ore carbon powder into refined steel in proportion. At the same time, he can also complete the final shaping. He can make as big a bearing as he wants.

How big of a bearing should be made?

How much iron does a bearing cost? But it can play a huge role!

The quartermaster in charge of the entire thousand-man army was on the same level as General Yang Hongru, so Yang Hongru couldn't stop him from messing with the transport vehicle. After some experiments, Yang Hongru separated the wheels and axles with bearings.

As a result, the wheels of the carriage became much smoother.

Listening to the rustling sound of the rolling steel balls in the bearing, Yang Hongru thought the sound was so beautiful - without bearings, these broken cars would make a squeaking sound as they walked, which was very unpleasant!

The soldiers transporting grain and grass immediately felt the difference after driving the carriage with the bearing replaced. The horse was still the same horse, but the speed was significantly improved, and more importantly, the horse was no longer tired!

Hua Mulan's eyes are full of little stars.

Appeared! Appeared!

The spirit of invention from the Mulan Clan's Great Witch Festival appears!

When Hua Mulan was a child, all her toys were made by Yang Hongru. When she looked at Yang Hongru who was studying them, she seemed to have returned to those days.

After replacing all transport vehicles with rolling bearings, the speed of the fleet transporting grain and grass doubled, and the consumption of horse feed was also reduced by more than 30%.

The transportation speed has increased, the time spent on traveling every day can be reduced, and the time spent stopping for repairs can be increased. Taking advantage of this time, Yang Hongru stepped up training in various subjects for the soldiers - these trainings are life-saving on the battlefield.

The more skill you have, the more hope you have of surviving.

There are two groups of people in the grain and grass transportation team, one is the logistics transportation team led by the quartermaster, and the other is the cavalry escort team led by Yang Hongru. The two groups usually stay safe, but when they are camping, Yang Hongru and others are on guard outside.

, the baggage and food supplies are stored inside.

There is a way to set up camp - whenever you rest, you will lay the transport vehicle on its side to act as a wall, which can effectively prevent enemy cavalry from sneak attacks. The defenders can use the vehicle as a cover to calmly fire arrows to counterattack.

When soldiers shoot arrows, they usually flex their thumbs and press their thumbs with their head. This is a common posture for barbarians to shoot arrows on horseback. This posture is convenient for cavalry to shoot arrows on horseback. The advantages are labor-saving and fast shooting speed. The disadvantages are

Close range.

As for eating, everyone eats their own food - it's not that they have a bad relationship, but that there are differences between the arms, and the food and treatment are different. This situation is still the same today, and the food of the soldiers will never be as good as that of the pilots!

The training of cavalry is rigorous and there are many combat tasks, so the food rationing is skewed. In the Northern Wei Dynasty, the annual consumption standard for an ordinary infantry was 12 horses of silk and 12 shi of millet; one horse was given 5 grains per day.

Literally, the annual cost is 18 dan - and the cavalry's salary is more than five times that of the infantry... You can calculate for yourself how high their food standards must be!

Even if Yang Hongru is the captain of the transportation brigade and the soldiers under his command are escort soldiers, as long as their combat order is cavalry, their treatment will be based on the cavalry ration.

According to rumors, the top armored cavalry troops in the Northern Wei Dynasty were paid more than ten times that of ordinary infantry - and this does not include their personal income captured in battle!

Therefore, people on both sides cannot eat together, because this behavior violates the logistics system. However, Yang Hongru and the others can give their colleagues something, such as pheasants, rabbits, roe deer, etc.

The transportation of grain and grass is not just a matter of following around. Yang Hongru needs to send scouts to detect the enemy's situation nearby every day. Although they have not entered the war zone yet, the guys who eat the food of Jianghu are not vegetarians.

In times of war, it is common for people to fall into bandits and become bandits. Moreover, a very high proportion of these people are defeated - the combat effectiveness of these gangsters who have received professional military training is not inferior to that of the regular army, and their weapons and equipment are also comparable to combat troops.

Take Yanshan as an example, the most powerful band of gangsters can actually bring out a thousand cavalry! Cavalry! Cavalry! And these turtles have powerful crossbows!

Crossbows are different from bows. They are driven by mechanical power and are very powerful. Folks can hold crossbows, but they are not allowed to hide crossbows privately - this has been the case since ancient times. This shows the lethality of this thing.

If you don't do a good job in investigation and the grain and grass are stolen by the gangsters, what awaits Yang Hongru is either dismissal from office or death. If you can throw away such important grain and grass, what use do you have?
