Gao Ming named the mine he designed "Fudo Ming King", which sounds very lofty, but in fact, this kind of mine has another name in history.

Land mines.

That's right, the mine designed by Gao Ming was not his original, but had appeared a long time ago, that is, the land mine used by the Eighth Route Army to deal with little devils during the Anti-Japanese War.

The biggest advantage of this kind of mine is that it is easy to obtain materials and has great power, even if it is made of a clay pot, as long as it is large enough and the gunpowder is filled enough, it can still cause great damage to the enemy.

Gao Ming didn't know how the Eighth Route Army used to fire mines back then, so he could only think about it himself, and after thinking about it for a long time, he finally decided to use friction and fire to fire mines.

This kind of device, in fact, is a combination of flint and pinion, pinion with wire traction, as long as the wire can be pulled to drive the pinion to rotate, the pinion rotates and flint friction, friction with the spark, the spark can shoot the mine.

After designing the mine from appearance to structure, Gao Ming's face was full of emotion.

"The teacher is right, learn mathematics, physics and chemistry, and you are not afraid to go all over the world!"

At this time, the sound of a book attendant suddenly sounded outside the study.

"Your Royal Highness the Prince, dinner is ready!"

"Got it!"

Gao Ming agreed, then folded the blueprint of the mine and put it in his arms, and then walked out of the room with a smile on his face.

After dinner, Gao Ming asked Wu Mei to take Su Wan'er and them to visit the Furong Garden, in order to deepen the relationship between them.

Wu Mei Bingxue was smart and knew the intention of Gao Ming's move, so she took Su Wan'er's hand with a smile and went.

Seeing that they got along well, Gao Ming suddenly nodded with relief.

"Well, the harmony of the harem is the most important thing, in order to make their relationship better, why don't I organize them to fight a friendship cannon tonight?"

Thinking of this, Gao Ming immediately ran to take a bath, and after washing, he took out the tiger whip wine that he had soaked for more than half a month and drank two sips, which can be regarded as fully prepared.

That night, the red waves rolled in Gao Ming's bedroom, the artillery fire shook the sky, Gao Ming was defeated after two rounds of fighting, and the bedroom was quiet again.

When Gao Ming woke up the next morning, he found that he was the only one left on the bed, and he suddenly let out a long sigh when he looked at the few hairs left on the pillow that he didn't know whose it was.

"Alas, this group of women is really getting more and more disagreeable, eat dry and wipe clean and leave with their pants on, and they don't think about my feelings, at least give me a good morning bite or something, it seems that these women still need me to adjust and teach ...... slowly"

As he muttered, he got up, and the clerk and sword, who were guarding the door, knew that he was up, and immediately came in to serve him to dress and wash, and brought him boiled millet porridge and some pastries.

After putting on the clothes, Gao Ming casually picked up a piece of pastry and put it in his mouth, and then asked the waiters.

"Where's your crown princess?"

"Back to His Royal Highness the Prince, the Crown Princess and Meng Fengyi went to the garden with the military steward."

Hearing this answer, Gao Ming immediately nodded.

"Well, it's good to visit the garden, as long as they have something to do, speaking of which, I also got a trip to the ordnance supervisor, I won't be back at noon today, and you don't have to wait for me for lunch."

"Yes, His Royal Highness the Prince, the maid will go and let people prepare carriages and horses!"

After saying that, the waiter went out to prepare a carriage and horse guard for Gao Ming, and when everything was ready, Gao Ming got into the carriage and went to the ordnance prison.

When Gao Ming went to the ordnance prison, the craftsmen inside were busy, and there was the sound of "clanging" iron everywhere.

Looking at this hot scene, he immediately nodded with satisfaction.

"Well, it's a nice atmosphere!"

Since many craftsmen had never seen Gao Ming, and he was wearing civilian clothes, no one recognized him all the way, and it was not until he reached the innermost point that a man in a green official robe greeted him and bowed to him.

"The lower official Liu Tao didn't know that His Royal Highness the Crown Prince had arrived, and he missed the distance, and he hoped that His Royal Highness the Crown Prince would forgive his sins!"

is the so-called stretch out his hand and don't hit the smiling person, and Gao Ming didn't care about these red tapes, so he immediately waved his hand.

"Okay, those who don't know are not guilty, so be excused!"

"His Royal Highness Prince Xie!"

Seeing Gao Ming talking so well, Liu Tao's face suddenly flashed with a hint of joy.

"Your Royal Highness the Prince, the cannon you commanded has already ordered someone to supervise the construction day and night, and in three days at most, the first one will be built!"

"Well, that's fine!"

Hearing Liu Tao's words, Gao Ming nodded suddenly, and then took out the mine drawings he had drawn yesterday from his arms and handed them over to Liu Tao.

"This is my newly designed weapon, you find a few people to make it, today I will stay in the armory prison for a day, if there is anything I don't understand, you can ask me!"

"Yes!"

After receiving Gao Ming's order, Liu Tao immediately found a few craftsmen and began to make mines.

Because Gao Ming marked it very clearly on the drawings, and he was in charge of the ordnance supervisor and could solve the problems of the craftsmen, the craftsmen made the mines very smoothly.

Now that something has been made, all that's left is to see if it can be used.

Gao Ming didn't know how powerful this mine was, so he had to choose the experimental site outside Chang'an City.

In order to confirm the lethality of the mines, Gao Ming also had a horse tied to the place where the mines were laid, and a straw man wearing leather armor was tied to the horse.

After everything was ready, Gao Ming tied the mine's firing device with a rope, and then took the rope and retreated to a place twenty meters away to lie down.

Seeing Gao Ming's movements, Liu Tao and several craftsmen who came with him were all stunned.

"His Royal Highness the Crown Prince, you are ......"

Gao Ming didn't intend to explain so much to them, so he pressed his hand directly towards them.

"Don't talk nonsense, get down, you'll know later!"

"Uh...... Yes, His Royal Highness the Prince! ”

They didn't dare not listen to Gao Ming's words, so they all learned to be smart and lay on the ground.

When everyone was ready, Gao Ming suddenly grinned.

"Hehe, you're all right? I'm going to do it, I'm going to do it, kindly remind you, you guys hurry up and cover your ears at the end! ”

When Gao Ming said the last word "Duo", his hand pulling the rope also pulled violently!

"Boom!"

Suddenly, an earth-shattering loud bang suddenly sounded, and along with this sound, there was a strong shaking of the ground.

Gao Ming had already been mentally prepared, and he had already stuffed a strip of wet cloth in his ears, so the loud noise did not affect him much.

But Liu Tao and the others were different, they were caught off guard, and they were immediately stunned by this loud noise, and their big mouths could even be stuffed directly into an egg.

Seeing this scene, Gao Ming immediately grinned.

"Hehe, you know that's amazing, right?"

But what Gao Ming didn't expect was that as soon as his words fell, Liu Tao shouted at the top of his voice.

"What? What did you say, Your Royal Highness the Crown Prince? The lower officials can't hear it! Xiaguan's ears are 'buzzing'! ”
