Yang Ling said as he took out a stack of papers from his arms and spread them on top of the case.

Huang Yueying handed Yang Yue to the nurse on the side, picked up the paper and looked at it carefully.

I saw that the things painted on it looked a little strange.

Underneath is a boxy cabinet with four copper pipes attached to a long cylinder placed horizontally.

"Husband, what the hell is this?"

Huang Yueying's fair face was full of doubts and incomprehension.

"It's called the Fierce Fire Oil Tank."

Yang Ling smiled slightly, pointed to the drawings, and explained to Huang Yueying.

"You just have to do this, and the oil will spew out......"

"Oh yes, you haven't seen oil, have you?"

Yang Ling asked Zhou Cang to take out a jar of oil and show it in front of the women.

Although they were surprised that the oil would not be extinguished by water, the women were still not interested.

After seeing the excitement, they dispersed and went back to their rooms to rest.

"How, can it be made?"

Yang Ling was full of anticipation.

"It should be possible, but it will take time."

Huang Yueying nodded.

"Great, Yueying!"

Yang Ling smiled and kissed Huang Yueying on the face.

Although she is already an old husband and wife, Huang Yueying can't help but blush.

As early as the Northern and Southern Dynasties, oil was used in warfare.

But at that time, most people used oil as an arson material.

It wasn't until the Song Dynasty that gunpowder was used in the military, and the craftsmen at that time invented the world's first fierce fire oil tank that could breathe fire continuously.

Its structure and principle are very similar to those of modern flamethrowers.

In his previous life, Yang Ling, when he visited the History Museum, saw a fierce fire oil tank.

He was extremely interested at the time, and he specially studied it, but he didn't expect it to be used today.

"Don't worry, husband, within seven days, you should be able to come up with the finished product!"

"Thank you, ma'am!"

Yang Ling is overjoyed!

……

After the end of the Liangzhou War, it was rare for the Han Empire to calm down.

Yang Ling also stayed in the house leisurely, accompanying his wife, concubine and children.

Occasionally, he would cook, cook a large table of delicacies, and invite Zhao Yun, Gan Ning, Ma Chao and others to the house for a few drinks.

Finally, on the sixth day after Yang Ling returned, Huang Yueying sent someone back from the craftsman workshop responsible for researching and building ordnance to inform Yang Ling that the fierce fire oil tank had been built.

Hearing this news, Yang Ling was immediately in good spirits.

He immediately asked Zhou Cang and Pei Yuanshao to call Zhao Yun, Gan Ning, Ma Chao, Pang De and other military generals who had good relations.

The group left Xudu City and went straight to the craftsman workshop outside the city.

After much interrogation, they finally came to a courtyard.

At this time, Huang Yueying was leading a group of craftsmen to inspect the copper cabinet in the courtyard.

Seeing Yang Ling and them coming, Huang Yueying dropped the work at hand and stepped forward with a smile,

"Husband, several generals, you are here."

"Thank you, ma'am."

Yang Ling nodded with a smile and looked towards the copper cabinet.

Although there are still some subtle differences, it is generally certain that this is the fierce fire oil tank!

"This thing...... Is it really that powerful as Brother Ziyi said? ”

Gan Ning circled around the fierce fire oil tank and muttered.

"Hey, since you don't believe it, then I'll open your eyes!"

Yang Ling nodded at Huang Yueying.

Huang Yueying immediately beckoned a team of craftsmen and asked them to take the fierce fire oil tank to a school field specially used for training ordnance.

I saw more than a dozen dummies made of wood and straw piled up on the flat ground.

The craftsman in charge of operating the fire tank first ignited the gunpowder contained in the copper pipe called the pump barrel on it.

They then pumped the pump hard and compressed the air into the tank.

"Whew!"

A scorching dragon erupts from the fiery oil tank!

Despite the distance, everyone still felt a wave of heat rushing towards them!

And the dummy, which was twenty steps away from the fierce fire oil tank, was directly devoured by the fire dragon!

Not to mention other people, even Yang Ling was stunned when he saw this scene!

Obediently, twenty steps is thirty meters faster!

When the two armies are fighting, if they come up like this, who can withstand this?

The most important thing is that the fierce fire oil tank is not only lethal, but also shocking!

Just imagine, the person who was sprayed had a raging fire on his body, and he couldn't put it out at all!

They screamed and wailed incessantly until they died!

Seeing this, will his companions lose their courage?

“…… Brother Ziyi, it's my vision that is small. ”

Gan Ning swallowed his saliva and said dryly.

"If this thing is used to defend the city, it is extremely powerful!"

Pound touched his chin and groaned.

"It's not limited to defending the city, if it is used for water warfare, it is also the most suitable!"

Gan Ning interjected.

When Yang Ling heard this, his eyes lit up!

That's right.

In the future, when he fights with the Jiangdong Naval Army, he will come to Sun Quan's warship like this, and he will fight with himself with his fart!

Thinking of this, he couldn't help but feel overjoyed.

"Next, I still have to ask Mrs. to mass-produce fierce fire oil tanks."

"The process of the fierce fire tank still needs to be refined, but this is nothing. If you want to mass produce, there are other problems. ”

Huang Yueying's eyebrows furrowed slightly, and she said with a wry smile,

"It's too copper-intensive."

The common thing in the world was not silver, but copper coins.

The whole body of the fierce fire oil tank is made of copper, and at least it will consume the equivalent of hundreds of thousands of copper coins!

"Madame, depending on the situation, let's make as much as you can."

Yang Ling comforted a few words, and thought in his heart, should he vigorously promote silver, or find a way to discover more copper mines?

After visiting the fierce fire oil tank, everyone left the craftsman's workshop with some unsatisfactory feelings.

Until he returned home, Yang Ling was still thinking about how to get more copper to build more fierce fire oil tanks.

"Husband."

Mi Zhen suddenly screamed.

"What's wrong, Zhen'er?"

Yang Ling was a little strange.

"Sister Qing just came back from the Wei Mansion, and for some reason, she looks in a bad mood."

Mi Zhen reminded.

Yesterday, Cao Qing greeted Yang Ling and said that she was going back to her parents' house.

Both of them are in Xudu, not far away, Cao Qing has to go back every once in a while, and Yang Ling doesn't take it to heart.

But I didn't expect Cao Qing to be a little unhappy when she came back today.

Is something wrong?

Yang Ling was puzzled and walked towards Cao Qing's room.

Sure enough, as Mi Zhen said, Cao Qing was sitting there sullenly, and Guo Zhao was helping to coax Yang Yuan.

"Madam, what's the matter, could it be that someone provoked you?"

Yang Ling smiled and sat down beside Cao Qing and took her in his arms.

"It's still because of you, husband."

Although Cao Qing leaned on his shoulder obediently, her red lips pursed, obviously unhappy.

"I didn't do anything for my husband, why did I mess with you again?"

Yang Ling said innocently.

"Today's incident, it's really my husband who provoked Sister Qing."

Guo Zhao on the side pursed his lips and smiled.
