Yang Yi smiled and didn't speak, motioning for Liu An to continue watching.

In the distance, the mechanical team received Yang Yi's order through the flag, and the commander shouted: "Prepare to shoot Zhu Yuan!" ”

"Direction, Xuanwu twenty-nine, angle seventy!"

The three tall trebuchets slowly turned their direction to face the troubled pile.

"Reloaded, positioned!"

"Ready....put!"

"Bang! Syllable! Syllable! Three sounds, three black balls flew straight out.

Under the amazed gaze of everyone at the head of the city, the three black balls flew in the air as if they had wings, and landed accurately on the pile of rubble nearly six hundred steps away.

Li Cen and Liu An were surprised, and suddenly three loud noises came, and three black balls exploded violently, and the chaotic land that was several feet square suddenly fell into a sea of fire, and it was difficult to think about what kind of consequences would be brought if this black ball fell into the military formation.

"It's... This..."Liu An, the assassin of Qinzhou, was already speechless.

Nanguo Marquis Li Cen was scheming and calm, but at this time he was also frowning, and turned his head to look at Yang Yi waiting for his explanation.

Yang Yi was very satisfied with the expressions of the two, and said with a light smile: "Don't be surprised, this is just a trebuchet and thunderbolt newly invented by my Shu army, the power is average, and there is still great room for improvement." ”

Li Cen exclaimed: "Can it be improved? ”

The range of 600 paces and the huge power of live ammunition are enough to become a big killing weapon on the battlefield, and if there is still room for improvement, it will not become a terrifying existence that hurts the enemy thousands of miles away.

Yang Yi smiled and nodded, he was telling the truth, the trebuchet was only transported from Wuzhi Mountain in Shuzhong to Qianzhou Mansion a few days ago, although the power and range were several times higher than that of ordinary trebuchets, but it was far from reaching Yang Yi's, especially the ammunition, although the ammunition of the trebuchet could produce some explosive power with gunpowder, but it was far from the real bomb.

Even so, the power of trebuchets and thunderbolts was enough to make Li Cen's eyes red.

Yang Yidao: "Guohou, do you think such a sharp weapon can be effective against Yang Jie?" ”

Li Cen paused for a moment, and said with some excitement: "What does Your Highness mean that the old man can buy these trebuchets?" ”

Yang Yi said with a smile: "Of course, I will give these three trebuchets to the marquis, if the marquis still wants to need more trebuchets and thunderbolts, he can place an order with Shuzhong, but because the manufacturing cost of these machines is relatively high, the price..."

Li Cen glanced at Yang Yi and bowed his hand and said: "Your Highness is willing to give you a treasure, the old man is grateful, and the price is easy to say, but I see that Your Highness's soldiers who operate trebuchets are professionally trained. ”

Yang Yi secretly said that Li Cen is really an old fox, he doesn't care about the price with himself at all, but pays more attention to the mechanical operator, he is worried that Yang Yi will sell something to him, but he himself will not use it, it is no different from a pile of garbage.

Yang Yi said: "The Marquis can rest assured, if the Marquis orders these trebuchets, I will send the corresponding number of technical instructors and instructors to help the Marquis train operators, and wait for the soldiers below you to learn the operation before paying, and the Marquis will not be disappointed." ”

Li Cen nodded, and looked up at the trebuchet team in the distance, just as everyone was talking, the trebuchet had been disassembled, and the trebuchet parts were neatly reloaded back into the transport vehicle by the soldiers, and slowly returned to the Shu army formation.

Yang Yi said: "Guohou, the city tower is windy, let's go down and talk about it." ”

Li Cen answered, did not speak, and followed Yang Yi to the city.

Of course, Li Cen knew why Yang Yi would sell such a battlefield killing weapon to himself, naturally in exchange for the land of Qinzhou.

For Li Cen, this does not seem to be too difficult to choose, the barren land of Qinzhou is actually not in the plan that Li Cen must fight for, the reason why he and Yang Yi fought for Qinzhou is entirely because of this southern battle, although the Linjiang army conquered the entire territory of Zhuzhou, but it was far from achieving its expected benefits.

With such a powerful trebuchet force, it is obviously not comparable to a small Qinzhou Mansion, with such a weapon of war, the combat power of the Linjiang Army will be increased by several grades, and it will be much easier to attack the city, and it is only a matter of time before the territory is expanded.

In addition, the reason why Li Cen seemed a little hesitant was just because he couldn't understand why Yang Yi did this, through Yang Yi's words and Li Cen's understanding of the war in Qianzhou, this powerful trebuchet force Shu Army itself has not been equipped, and this kind of trebuchet did not appear in the first battle of Qianzhou, how could Yang Yi be so generous and sell this war machine to himself for a land in Qinzhou.

Of course, Li Cen didn't know that this kind of trebuchet was just a defective or excessive product in Yang Yi's heart, although its power had surpassed that of any long-range attack weapon in this era, it was still far from Yang Yi's expectations.

Yang Yike is a man who wants to shoot artillery, and artillery is the real long-range killing weapon in his mind.

In addition, since Yang Yi entered Shuzhong, he wanted to make Shuzhong a technologically advanced commercial country, what is the most profitable in real business? Not food, not silk, but weapons.

Weapons are the most direct manifestation of whether a country or a power is strong or not, it can also be said to be dependent, especially in times of war, the supply of weapons is definitely a huge profit, in the previous life, the United States was in two world wars, not only relying on the sale of weapons and equipment to obtain high war profits, and when other countries become dependent on their own weapons, even if they do not join the war, they can also affect the outcome of the war.

In the early middle and early stages of World War II, the United States sold weapons and materials to China at the same time, and also sold strategic materials to Japan and Germany, and the huge profits made from it were absolutely incalculable; when the war was close to stalemate, the United States went to war against the German and Japanese fascists, and finally not only obtained a large amount of economic profits, but also became the savior of the world, which can be described as both fame and fortune.

Of course, Yang Yi knew that Li Cen would find a way to develop his own after buying the trebuchet back, and this kind of thing is not something you can know the process if you know the result, and the national government purchased countless American-made equipment and German-made equipment, but it has not seen that it can independently develop any decent products.

Even in New China, without the interference of war, it took decades for the Celestial Empire to gradually catch up with the pace of the world in science and technology, and it was still a long way to go to surpass the Western powers.

For these trebuchets and thunderbolts, not to mention the development of gunpowder in thunderbolts, Yang Yi, a traverser, has not yet found the trick, and others have no way to figure out the principle.
