Although Li Yu has formulated the next battle plan with Yin Leiya and Du Lun and others, there is still a lot to do.

Night battle is a magical tactic that can defeat the strong with the weak. The attacker takes advantage of the darkness of the night to minimize their disadvantage in numbers or equipment.

In the Korean War, the volunteers caused great trouble to the U.S. military through the elusive night battle, making it difficult for the U.S. military to give full play to its artillery fire and air superiority.

But it is not easy to organize a successful night battle. There will only be more night battles than those who win and lose.

The greatest difficulty in this is the command, especially for the medieval army, which was inherently loose and the ranks were patchwork of various families, and it was not easy to enforce the ban.

For example, Hugo was unwilling to obey the orders of the Marquis of Cullen and led people into the Dragon Crest Mountains alone, which was of course a conspiracy between him and those dwarves, but it was not a strange thing for the nobles on the continent of Brattis.

As a vassal party, it is obliged to respond to the monarch's call, fight for the monarch, and often have to bring its own dry food, so it is reasonable to grab a little robbery on the road and make some extra money to make up for the loss.

In many cases, even the monarch is not very good at preventing such behavior. This is also the reason why Cullen and others did not suspect Hugo much before.

And this situation still exists in Miss Rabbit's place, except for the two thousand people she brought herself, the rest are warriors from other families.

Nominally, these people will obey the orders of her commander, but in fact, according to the long-standing tradition on the mainland, if Yin Leia wants to send these people, she must first give the order to the nobles who lead the troops.

Then it was conveyed by those nobles to the knights under them, and finally the knights were responsible for leading their respective warriors to carry out the orders, and the intermediate links were mostly on the one hand, and the most important thing was that these people also had a certain degree of autonomy.

Although it will not openly disobey the orders of Yin Leiya, the commander-in-chief, it is bound to bring chaos to communication.

It's okay to say during the day, I'm messing with you, everyone can just mess around. But night fighting is definitely not good, before they reach the battlefield, they first scatter two or three adults, and then after a chaotic rush, their own people fight with their own people, pushing and trampling each other, plus falling into the ditch...... There is no need to fight this battle, you can directly admit defeat.

In order to avoid such a situation, the first thing Yin Leiya had to do was to reorganize the army and achieve unified command and unified scheduling.

However, for thousands of years, everyone has become accustomed to the previous way of organization and warfare. Yin Leiya wanted to convince the noble generals of other families that it was not easy to give up the right to send troops for the time being.

Fortunately, she has the title of champion of martial arts, and when the black dragon ravaged the Western Realm before, she also stepped forward and successfully slayed the dragon, so that the major families in the Western Realm owed a favor.

But the most important thing is that in those battles not long ago, the female lord proved her command skills by borrowing the sound sacred weapon of the Shuangxiu Sect.

She has led the big guys to several victories, knocked out the dwarves near Gravel Valley, and the name of the Imperial Valkyrie is getting louder and louder.

In addition, the strong enemy is currently strong, although the food crisis has been temporarily solved by looting those savage tribes, but if they can't defeat those dwarves blocking the road, they can't leave the valley for a day, and they are always in danger.

Therefore, everyone finally agreed to the female lord's proposal. So the girl then broke up and reorganized the 8,000 people on hand into 16 brigades, each with 500 people, equipped with a wireless walkie-talkie.

This allows for real-time command as before, while teams can communicate and cooperate with each other.

In addition, the female lord also agreed on a code in advance to distinguish between friend and foe. Those who can pick up the code are their own people, and those who can't be connected are the enemy, and when the time comes, it's over.

Of course, it's not enough to just touch the dark and cut blindly, there must be light. However, the light in night combat is a double-edged sword, which can not only be used to identify targets, causing psychological oppression to the enemy, but also exposing oneself and becoming the target of fire.

However, there are drones on the female lord's side, and Li Yu plans to install searchlights on them to provide lighting for the army.

Since drones are in the air, as long as they rise to a certain height, there is no risk of being attacked, and they can calmly search for targets in enemy forces.

Dump the beam on the target and turn it into a target for your archers. These beams of light themselves have a certain blinding effect, and the sudden appearance of white beams of light above the sky can also cause deep fear in the hearts of enemy soldiers.

They can also be used to aid commands, pointing out the direction of attacks to soldiers who have not heard orders clearly.

However, considering that the civilian drone will return to charge in about thirty or forty minutes, this requires Li Yu to bring more batteries.

In addition, Li Yu also purchased a batch of luminous paint, which can be painted on the faces of the warriors at that time, which can further intimidate those dwarves, and can also be used as a kind of identification.

Finally, of course, there is an old friend, the Molotov cocktail. As soon as Jacobi died, there was no one in the sky who was Zhu Zhigang's opponent.

And Li Yu also intends to give full play to his air superiority. He specially equipped Zhu Zhigang with a pair of night vision devices, so that Zhu Zhigang did not need to use any light to carry out activities, which could ensure his safety to the greatest extent.

Carrying a Molotov cocktail can completely transform into a stealth bomber. Then he will go and burn the food and grass of the dwarves, and further cause chaos among the dwarves.

Li Yu made a list, wrote down all the things he wanted to buy, and then calculated the price, and found that the reimbursement amount for next month was not enough.

Fortunately, the short video accounts he opened on several platforms are currently improving, in addition to some income brought by the playback, there have also been business orders coming to the door, and Zhang Yanlin has been actively contacting the other side.

It is estimated that new income will arrive soon, so Li Yu continued to cushion the money by himself. And he simply didn't do anything, and purchased thirteen drones, all of which were ready to be put into the next big battle, ensuring that each squad could have at least one drone to work together.

In the end, all kinds of things were added together, and the total expenditure had exceeded 80,000 yuan, and Li Yu could be regarded as bleeding for the next battle.

He spent the next few days carrying these things in batches. On the other plane, while the female lord continues to sweep through the savage tribes, she also takes this opportunity to actively train the new army that has just completed its reorganization.
