Using the eight-ox crossbow to launch a large bamboo pole filled with gunpowder is Liang Baoyu's proud work.

The new weapon originally developed by the Ministry of Industry was a cannon battle, and it really went to the battlefield, whether it was a field battle or a siege city, and if you wanted to send a big bamboo pole to the enemy, you don't know how many lives you have to fill it in.

After combining with the Eight Bull Crossbow, it became different, although the Eight Bull Crossbow originally reduced the killing distance of nearly 1,500 meters to 1,000 meters, but the power is not the same!

In particular, the siege effect that the Ministry of Industry cares about the most, the large bamboo pole shot by the eight-ox crossbow five hundred meters away is enough to penetrate the city wall, and if it encounters something of poor quality, it may be able to penetrate it.

The development of the new cannon is not complicated, and the original mature technology has been slightly modified, which is enough to meet the firing requirements of the eight-bull crossbow.

The people of the Ministry of Engineering have learned well this time, and the viewing platform has retreated hundreds of steps, so that the veterans keep shouting, they can't see clearly from too far away, and they are all hard-mouthed, saying that the distance last time was very good, and it was nothing more than a matter of going home to take a shower after watching the cannon battle...... I forgot who was shocked to pour a mouthful of sand last time and didn't know to shut up!

As for bringing the gentlemen to join in the fun, Liang Baoyu is really not just for fun, these gentlemen will grow into the mainstay of the Tang Dynasty in the future, and there are a lot of people who can leave a mark in the history books alone, and the Tang Dynasty will be fighting in the south and north in the next few decades, and from now on, it will leave the impression of new weapons on these people, which can be more effective than special class training.

"A-shaped rocket test launch demonstration, start now!"

The lieutenant holding the small flag waved his arm, and the sound of the spring activating like the sound of tearing cloth exploded instantly!

"That's not right!"

In the midst of the squirming, Cheng Chumo knew the goods, and suddenly exclaimed!

The powerful kinetic energy suddenly exploded, and the cannon battle with the adjusted shape was like a black lightning bolt, piercing the air with a sonic boom like a ghost's scream, and directly hit the target earthen wall!

Five hundred meters, through!

The A-shaped rocket was directly nailed into half of the second earthen wall, and the power displayed far exceeded the strength of the Eight Bull Crossbow!

Rumble!

Filled with improved granular gunpowder, the explosion of the A-shaped rocket was far more destructive than the previous cannon battle, and the second earthen wall was directly wiped out, and the first earthen wall that was penetrated was also collapsed by the aftermath!

Unlike those bigwigs on the viewing platform who can get close to observe after the explosion, the gentlemen belong to the kind that rubs and can't enter, so they can only pull Liang Baoyu to ask, but most of them are gibberish under excitement, and the entry threshold for this thing is still a bit high at the moment.

"Old eight, the sound of the eight-bull crossbow is not right, and why is it ...... Uh, rockets, yes, rockets that much when they're in the air? It's not the same as the original! ”

Cheng Chumo, together with several other gentlemen who had been trained in the army, pulled Liang Baoyu's sleeve and did not let go, so that Liang Baoyu, who was about to come forward to check the effect of the A-shaped rocket test explosion, could not move.

"Don't mess around, don't meow mess! Listen to me, come one by one! ”

Liang Baoyu shook off the five or six big hands on his body, and screamed a few times at the top of his throat, which quieted down the gentlemen who were so excited that their eyes were red, "The Eight Bull Crossbow has been transformed by me and the people of the Ministry of Industry, and the activation device and the accumulator have all been changed, confidential, no comment, who of you can use this thing in the future, naturally there are people in the army to tell you in detail."

I'll just say that the Eight Bull Crossbow, which originally required eight to ten people to operate, now only needs two people to use, and it can fire three arrows in a quarter of an hour, but now it can shoot more than ten!

As for the sound of the rocket flying in the air, it is specially equipped with a bamboo whistle...... In the future, any enemy who hears the sound of a bamboo whistle will be frightened by my Datang rockets! ”

In fact, the truth is far more complicated than Liang Baoyu revealed.

The Eight Ox Crossbow has been redesigned to the greatest extent possible, and the use of standard parts minimizes the dependence of this thing on logistics and supplies, avoiding the situation that a small damage to one part has to abandon the entire weapon of war.

The spring that excites the arrow was replaced with mild steel, and the tungsten ore found by Liang Baoyu in the warehouse of the Ministry of Industry and the rough primary tungsten alloy were made out by him, and the new spring made of three mild steels had strong kinetic energy and was incomparably powerful!

The device that accumulates strength has been redesigned into a gear winch, which can be operated by ordinary strong men alone, so that the excitation frequency soars several times!

The design idea of the A-shaped rocket still focuses on breaking the city wall, and the use of particle explosives made the city walls all over the world tremble in the early Tang Dynasty.

"Brothers, with this thing as a rocket, the battle formation will be different from the past in the future!"

Liang Baoyu believes that with the increase in gunpowder production and the continuous emergence of gunpowder weapons, in the future, the soldiers of the Tang Dynasty will redesign countless new combat methods around gunpowder. ”

This is the ultimate goal of Liang Baoyu to bring the gentlemen into the test site, and it will inevitably take a long time for the gunpowder weapons to be officially installed, but it is serious to leave seeds in the hearts of the younger generation and let them have a concept of gunpowder.

"Yo, Yongxingbo is so lively here!"

"I've seen Wei Neishi!"

"This A-shaped rocket is really powerful, Your Majesty is very satisfied, summon Yongxingbo, come with our family, Ji Guogong has already passed."

Leaving behind the gentlemen, Liang Baoyu followed Wei Taizhong and hurriedly went to face the saint.

The observation post where His Majesty Li Er was located was farther away from the blasting site, but the line of sight was very good, and when Liang Baoyu arrived, Duan Lun, the secretary of the Ministry of Works, was reporting.

"Yongxingbo, Ji Guogong just said, you suggest that the B-shaped rocket that has not yet taken shape be sent to Shuofang for actual combat testing?"

"Yes, Weichen believes that in the next few years, the biggest threat and enemy of my Datang will inevitably come from the grassland, although the A-shaped rocket is full of power, but it cannot play the greatest role on the battlefield in the wilderness and flat terrain, and the B-shaped rocket being developed can fully meet the needs of the grassland campaign!"

"I know that you miss your father, and Cangwu County is indeed under a lot of pressure to garrison Shuofang, but the B-shaped rocket you said ......"

"Your Majesty, the B-shaped rockets are lighter, have a longer range, and have a charge of one-third less than the A-line, but Wechen intends to mix iron sand, iron nails, and even scrap fragments from the blacksmith's shop into them...... As long as the B-shaped rocket detonates in the middle of the enemy's formation......"

"You kid! Hehehe, Ji Guogong, what do you say? ”

His Majesty Li Er just wanted to open his mouth to educate Liang Baoyu, but he stopped again and again, and turned his head to look at Duan Lun, the Duke of Ji Guo.

"The old man thinks this move will hurt the heavens and the peace!"

Duan Lun looked upright, "But compared to Yongxingbo's reputation...... It's nothing! ”
