"This flower can only be found in heaven, and is rare to see on earth."

Xiao Liu was so excited that she casually adapted a poem, which made Zhang Yi faint.

After thinking about it for a full minute, Zhang Yi remembered that she was adapting Du Fu's "Giving Flowers to the Queen". This song should only exist in heaven and can only be heard several times in the world.

Zhang Yi would feel uncomfortable if he couldn't remember it. He is such a perfectionist.

"By the way, Xiaolong," Xiaoliu pulled Xiaolong to her side and asked quietly, "How much does this fireworks cannon cost? How much does it cost to set off hundreds of them when we celebrate our victory?"

"If you put a few hundred pieces, it will cost several hundred taels of gold," Xiaolong said with a smile. "In terms of cost, one piece will cost at least one tael of gold, sister-in-law. We need to purchase and produce various raw materials, which will be mixed together by professionals in proportion.

You also have to put in different metal scraps to achieve colorful effects.”

Xiaolong did not deliberately study fireworks bombs. In the process of preparing gunpowder, different explosion effects appeared, which can be applied in many aspects. Fireworks and firecrackers themselves are a specialty of China. If they are developed, the market prospects will be infinite.

"Oh, it's not expensive. It's still worth it. We can get back 7,000 tons of gold from the Japanese family," Xiaoliu said with joy, "What do you think, brother-in-law?"

Ha, Zhang Yi doesn't know what to say to the director of the National Bank. She has already regarded the 7,000 tons of gold as her own.

"Well, it's not expensive. It's worth it to make hundreds of thousands of people in the city happy." Zhang Yi nodded.

"Haha, now, I want to shoot again!" Xiaoliu pleaded.

"Liu'er, why don't you give it up?" Zhang Yi was a little embarrassed. Today he came to test-fire the artillery, but Xiao Liu became addicted to it.

"I'll pay for it myself, okay?" Xiao Liu said, refusing to give up.

"Okay, my sister-in-law will fire off another cannon, and it's my treat." Xiaolong chuckled.

When it came to this, Zhang Yi had no choice but to agree.

He was just afraid that everyone would think the princess was playful... Zhang Yi looked at it, "Hey guys," everyone looked happy, waiting for the princess to light another firework bomb.

People can't get enough of this magical fireworks.

So, Xiaoliu had another addiction.



"Prime Minister Xiao!" As soon as Xiao Han arrived, Xiao Liu said with a smile, "I set off two beautiful fireworks cannons, I believe you all saw them!"

"I saw it, Your Highness, she is extremely beautiful!" Xiao Han clapped his hands and laughed, "I think the effect will be even better if it is at night!"

"Oh, you are right, those colorful lights will be more vivid at night!" Xiaoliu said with a little regret.

"Okay, when the fireworks show is held, I will let you have a good time." Zhang Yi comforted Xiao Liu and then said to Xiao Han, "Pull out our artillery, I hope it will be a hit!"

"Definitely, Brother Yi!" Xiao Han nodded vigorously.

The development of artillery took countless people's efforts.

Zhang Yi participated in the research and development of the team and knew the difficulties involved.

During the research and development process, several ideas emerged.

Some people suggest that large-caliber muzzle-loading guns should be developed because the technical difficulty is relatively low.

The larger the caliber, the greater the power. The problem is that the weight of the gun body reaches an alarming level. This is the characteristic of the artillery in the Yuan Dynasty.

Those who suggested the production of large-caliber artillery believed that there would soon be steam armored vehicles and large iron-clad battleships with large loads, and there would be no problem in transporting artillery.

It seems reasonable. Large-caliber artillery can level the enemy's fortress with one or several shots. Who wouldn't want such artillery?

But Zhang Yi felt something was wrong.

He thought hard all night and determined the research and development ideas.

No large-caliber guns, no muzzle-loading guns, huge size and weight, or seriously affecting the speed of armored vehicles and battleships.

"We don't want big ships and big guns, we want fast boats and fast guns." Zhang Yi made this clear.

The truth is this, once Zhang Yi explained it, everyone figured it out.

The small cannon has strong maneuverability and fast firing speed. When attacking a fortress, it can make up for the lack of power through intensive firepower. When attacking the enemy's position, this advantage is even more obvious. When the enemy cavalry charges over, it is better to fire two cannons.

, or ten shots is better?

The answer is of course the latter.

Only then did the opinions become unified.

It’s difficult. There are different technical routes for doing everything. When there are different opinions and it is difficult to make a decision, the wisdom of the leader is tested.

Zhang Yi has such wisdom, but it’s a bit brain-consuming.

The research and development goals are clear.

The armored vehicle is equipped with a 50 mm caliber gun.

The battleship is equipped with 88 mm caliber guns.

Both are breech-loading guns. According to the information on artillery technology, a recoil recoil machine is installed on the artillery, so that the rear seat part of the artillery can automatically return to its original position using its own recoil after firing, eliminating the need for

The time for reset and re-aiming greatly increases the gun's rate of fire.

Of course, although there is previous information, the barrel processing is extremely difficult. Xiao Han, Hu Tiejiang and others tried their best, but the quality and power can only reach one-tenth of the original.

If it can be launched, that's fine.

The requirements cannot be too high, as long as it can launch, it can become the overlord of this era.



Arriving at the scheduled launch site, everyone worked together to unload the two artillery pieces from the eight-horse cart.

They are 50mm and 88mm caliber artillery, weighing about 800 kilograms and one ton respectively. When used in the future, they will be fixed on armored vehicles and battleships. This weight is not a problem.

The weight of the shells reaches 10 kg and 15 kg respectively.

The firing mechanism is of impact type.

Theoretically, it can fire more than a dozen rounds per minute.

As for the range and power, they are unknown, and we can only draw conclusions after test firings.

Zhang Yi stroked the gun body. It seemed that the quality of the gun barrel was acceptable. The requirements were not high. As long as it could fire one or two hundred rounds, it would be considered a success. The gun barrel was a consumable. Even if the quality met the requirements, it could fire a thousand rounds.

Fire cannonballs left and right.

Just imagine, the armored corps is equipped with one hundred 50 mm caliber artillery, firing 10,000 to 20,000 rounds, enough to sweep across the Eurasian continent. The Chinese fleet is equipped with one hundred 88 mm caliber artillery, and it can gallop across the four oceans. The great powers

No matter how big the wooden warship is, it can be blown to pieces with a few cannons.

Conquering the world depends on weapons like artillery.

Xiaoliu was also very excited, caressing the gleaming and cold steel cannon, praying constantly in her heart, hoping that it would be fired. In that case, no one could stop the advancement of the Chinese army.

"Please Zhang Shoufu, Her Royal Highness the Princess, and all irrelevant personnel retreat a hundred meters away," Xiao Han pointed to a hill a thousand meters away and said, "That is our goal!"

The atmosphere suddenly became tragic. If the test firing failed and the barrel exploded, everyone present would be shattered to pieces.
