Sima Zhao sat weakly on the brocade seat, looking at the urgent report presented by Guan Zhong, his mind seemed to be emptied, and his mind was blank.

Chang'an was lost, Sima Wang's army was defeated and self-immolated, this news was like a thunderbolt in the sky, and it really gave Sima Zhao a heavy blow.

How can it be? How can it be? How can it be?

Sima Zhao was deep in his heart, and he had already asked hundreds of times. You must know that Sima Wang's command was 100,000 elite soldiers, and in just a few months, he was completely defeated, not only losing all 100,000 horses, but also losing Chang'an.

Changan? To Chang'an! Chang'an is known as a big city on a par with Luoyang, with twelve city gates, the city walls are tall, extremely strong, and it was lost in three days. It's incredible.

"When Liu Yin attacked Chang'an, he used an unprecedented weapon, called gunpowder, and spent three days digging a tunnel under the southern city wall of Chang'an, burying thousands of catties of gunpowder under the city wall, and after ignition, there was a shocking noise, and the city wall of Chang'an collapsed, so Chang'an City would lose so quickly." Jia Chong explained to Sima Zhao in a heavy voice.

Any city relies on the city wall, and as soon as the city wall falls, the defense system of the entire city will be useless, and it is completely reasonable that Chang'an City was lost so quickly.

"Gunpowder?" Sima Zhao has a black line, Liu Yin can always make something amazing, the former in the battle of the street pavilion, Liu Yin was equipped with a new style of saddle stirrups, and that battle was also the beginning of Sima Wang's defeat. Cao Wei, known as the invincible Cao Wei in the world. In front of the new cavalry. Becomes vulnerable. Sima Zhao also felt the importance of scientific and technological innovation, and ordered a large-scale imitation of Takahashi saddles and bilateral stirrups to solve the problem of cavalry combat power.

And Liu Yin's novelties seem to emerge in endlessly, this time he actually made some "gunpowder", which is powerful enough to collapse the city wall, which is undoubtedly a terrible weapon, and the current war is all about the city to carry out offensive and defensive operations. And Liu Yin's weapon will inevitably break the existing balance, just imagine what a terrible thing it would be to have any strong city in front of him.

Jia Chong took out a small paper bag from the sleeve of his robe like a trick, opened it, and spread it out in front of Sima Zhao. Sima Zhao raised his eyes and saw that it was a pile of black fine powder.

"This is gunpowder?" Sima Zhao looked at these inconspicuous things and said with some surprise.

Jia Chong nodded, without words. Instead, he instructed the attendant to take a lit candle and move the gunpowder to an open space far away from Sima Zhao. He took another piece of paper, rolled it into a roll, lit it on the candle, and threw the flame at the pile of black powder.

"Boom!" The pile of black powder was ignited in an instant, and flames several feet long appeared, although Sima Zhao was far away, he could still feel the impact of the deflagration, and he couldn't help but shrink back.

"Where did you get this gunpowder?" Sima Zhao asked with interest.

Jia Chong said: "This is the sample that Captain Qingniao managed to get from the middle of the Guanzhong Military Division, if it weren't for that, we really don't know what Liu Yin used to collapse the Chang'an city wall." ”

Shu has always been in the leading position in the field of military technology, the sword cast in the Zhuge Liang era is sharper than the sword used by the Wei army, Zhuge Liang personally presided over the design and production of the Yuan Rong crossbow is a highly lethal weapon, but these weapons to the overall military strength of the promotion is limited after all, absolutely not to the point of overwhelming superiority, for Cao Wei, who focuses on the development of the overall military strength, it seems that the military technology innovation of Shu is not too cold.

However, after the Battle of Jieting, Sima Zhao also realized the importance of military technological innovation, in addition to the large-scale imitation of the Shu army's Gaoqiao saddle and bilateral stirrups, many previously shelved military technology projects were re-emphasized, such as the late Ma Jun's many inventions, which could not be put into practice during his lifetime.

At that time, Hongnong Taishou Fu Xuan had recommended Ma Jun to Cao Shuang several times, but he had not been reused, and had been ridiculed by Pei Xiu and others, Ma Jun's restructured crossbow and serial stone cart were shelved and failed to be applied to the military, Fu Xuan had to sigh repeatedly, saying that Ma Jun's author was the essence of the country, and the army wanted to use.

The Battle of Jieting was a major turning point, the extremely powerful Cao Wei cavalry was vulnerable in front of the Shu army equipped with new harnesses, and almost the entire army was wiped out, and such a tragic loss greatly stimulated Sima Zhao. After learning from the pain, Sima Zhao decided to make great efforts in weapon innovation, and Ma Jun's son **** was appointed as the middle of the matter, fully responsible for the management of the weapons workshops, and many of Ma Jun's inventions during his lifetime were also taken out and entered the stage of experimental production.

Sima Zhao saw the power of gunpowder, and couldn't help nodding frequently, just such a little bit can produce such a great power, no wonder thousands of catties of gunpowder can be piled up to blow down the city wall of Chang'an.

"If there is a sample, then hand it over to the **** in the matter, and let him copy the production." The Takahashi saddle and bilateral stirrups have entered mass production, and Sima Zhao has seen the tiger and leopard riders equipped with new saddle stirrups, and the combat effectiveness has been significantly improved, which makes Sima Zhao full of interest in scientific and technological innovation, and is also full of expectations for imitation gunpowder, and is eager to implement it immediately.

Jia Chong shook his head and said: "King Huijin, this thing has been shown to **** and craftsmen, no one knows what kind of thing this thing is made of, **** said that this thing is at least a mixture of several raw materials, if you don't know its recipe and process, it is difficult to imitate it." ”

Sima Zhao also fell into contemplation, obviously this matter is more difficult to do, the formula of gunpowder Shu Han must be regarded as a treasure, and it is definitely not an easy thing to obtain. But when he thought that the Shu army had such a powerful weapon, Sima Zhao couldn't sleep well, gunpowder was completely a weapon to break the balance of force between the two sides, if the Wei army could not master and equip it as soon as possible, then in the next battle, it would inevitably be at a disadvantage, such a situation was something that Sima Zhao absolutely did not want to see.

"The herald is the middle military division, at all costs, you must also get the formula of gunpowder!" (To be continued.) )
