"According to the mining engineering team, when they enter some mountains, Sinan will run around without direction."

Zhang Xingbang said, "It's hard to tell the direction with these ores!" I can only barely confirm the direction by relying on the sun. ”

"I see."

Ye Yu smiled slightly, and there was a burst of surprise in his heart.

"Your Highness, what are these stones?"

Zhang Xingbang asked.

"Yes, this kind of stone is newsworthy!"

Liu Yuanshan opened his mouth and smiled slightly.

The two spy chiefs thought of going together.

"I once saw a book that was lost overseas, and this seems to be the material used to make Sinan."

Ye Yu said slowly, "It's called a magnet." ”

"I didn't expect that there would be such a magical thing in the territory of King Anding!"

"What I didn't expect was that King Anding would let us mine so easily!"

Liu Yuanshan and Zhang Xingbang, you said a word, I said a word, and laughed.

"But Your Highness, what is the use of this kind of thing other than the Sinan compass?"

Zhang Xingbang asked, "Otherwise, we will have nowhere to use a large amount of mining." ”

"This is of great use in the back, so that the warlock don't study it casually, if you use it, you can use the Sinan compass."

Ye Yu said with a flash of inspiration, "By the way, make a simple compass and use it for the army." ”

"This ...... It should be enough to have Sinan, but the compass is used by those Taoist priests. ”

Zhang Xingbang was puzzled.

"At this level of class, above the squad leader, you must bring a small compass so that you can confirm the direction at any time."

Ye Yu said, "I have taught simple confirmation maps before, and all combat maps must be used at the class level. If you have a compass, you can check the direction more easily. ”

"It's really good."

Liu Yuanshan said, "It's easy to lose direction in the mountains and wilderness, if there is a compass......

"Don't forget that there are also such magnets in the mountains that can destroy the direction."

Zhang Xingbang shook his head as he spoke, "But it can be used in other places." ”

"The use of magnets will be discussed later, although I have a plan, but it is not yet this time."

Ye Yu said and waved his hand, so that this topic would end here.

"Your Highness, why isn't it time yet?"

"Do you think what would happen if I first came here and mass-produced flintlock pistols or even forced submachine guns?"

Ye Yu said the consequences of messing with the technology tree.

"This ...... The Southern Dynasty absolutely collapsed! ”

Zhang Xingbang said, and suddenly a chill felt behind him.

At that time, not to mention submachine guns, even flintlock pistols required a lot of steel.

If it weren't for Zhangye's mining from the south and mining in the mountains of Xishan Prefecture, I am afraid that it would not be able to support the amount of copper and iron at all.

Not to mention a rare treasure like gunpowder!

"yes, so this thing works, but it can't be used right away."

Ye Yu said, "This thing will change an era, and it is a very important thing." ”

Although he looks like a riddler, there is no way, you can't say that this thing can generate electricity, and in the future, you can build engines, cars, tanks, and airplanes, right?

They don't understand that!

It all has to be done step by step.

If he hadn't been stable enough and messed around with other TV series, the country would have collapsed a long time ago!

"Obey orders!"

Liu Yuanshan and Zhang Xingbang nodded, and they didn't say much about it.

"By the way, what should these people do?"

After being silent for a while, Zhang Xingbang asked.

"Let these people live over there."

Ye Yu said, "Give them food and let them live well." ”

"Huh?"

Liu Yuanshan was a little surprised, "Don't bring it in?" ”

"Bring it in, I don't have a problem, do you two want to make the work more difficult, I'll let you go."

Ye Yu said and smiled, "After fighting for so long, there are homeless people, it's obvious that this is not a homeless!" ”

Zhang Xingbang felt this.

"That'...... Why did His Highness take them in? ”

Liu Yuanshan was puzzled, "Do you want to win them over?" ”

"These people should not all be intelligence officers, they should be mixed with a lot of people."

Ye Yu analyzed, "These people should have been forced by life to come over with money." ”

"If you took the money, why did you ......?"

"There's nowhere to spend the money here."

Ye Yu said and smiled slightly, "Unless I let them in, right?" ”

"Indeed."

The two nodded and said, "But Your Highness, in this case, you only need the minister to be here, why should Your Highness come in person?" ”

"I'm going to reform them."

Ye Yu spoke slowly, "They let the people suffer in the ice and snow for their own selfish interests, how can I sit idly by?" ”

Saying that, he put his arms around Gongsun Ling'er, "This should be the Black Tiger's plan, wanting to rely on these homeless people to cover and sprinkle intelligence officers in." ”

"Liu Yuanshan, after we go over, you will set up a temporary newspaper and propaganda department over there to publicize the good of the Southern Dynasty to these people."

Ye Yu opened his mouth and said, "Zhang Xingbang, establish a temporary security office, ensure that there is no chaos among the people, and the rewards and punishments are clear, so treat them as the people of our Southern Dynasty." ”

"Obey orders!"

"Obey orders!"

The two of them spoke in unison.

"This should be his first move."

Ye Yu thought about it and said, "Their purpose should not be simply to send intelligence officers. ”

"What else?"

Gongsun Ling'er asked curiously.

"If you let them in, it should also disturb the Southern Dynasty."

Ye Yu immediately spoke, "Looking at their appearance, they should disrupt our development, and at the same time, Ye Lie can develop the final ......"

"There must be a war."

As he spoke, his face suddenly became serious, and he slowly spat out these words.

"If you want to fight, you shouldn't lose much to him now!"

Zhang Xingbang said.

"That being said, we don't have enough troops on our hands."

Ye Yu opened his mouth and said, "Three thousand people and three regiments." ”

"How much does that cost?"

Liu Yuanshan asked curiously.

"If you dig trenches according to the three-three system, at least 30,000 people will be needed."

Ye Yu slowly spoke, "These 30,000 people can have no combat experience, but they must be filled in the line for defense." ”

"If you attack, in addition to Yang Jiang's two regiments, you need at least six regiments, and eight thousand people will have a chance."

He added.

During this time, he was already thinking about Ye Lie's situation.

After such a battle, Ye Lie should have thought that he knew the shortcomings of the musket.

But I don't know that I have machine guns and artillery in my hands.

Therefore, if he wants to charge head-on, he will not be vain.

However, he couldn't guarantee that Ye Lie would learn the tactics he had used against him at that time.

If they can stick in and fight, their own people won't have enough advantage.

Also worried about him was the so-called tank.

After this battle, what will he change the chariot to?

"By the way, how is Ye Lie's situation now? I'm teaching at a military school these days. ”

Ye Yu asked thoughtfully.

"Ye Lie seems to be developing steadily, a lot of railways have been laid, and after occupying King Gong's territory, there are more ports."
