The "Shen Fire Flying Crow" is made of thin bamboo strips and cotton paper into a crow shape, filled with gunpowder, and is propelled by four rockets. It is the earliest multi-gunpowder cartridge parallel rocket in the world, and it is very similar to the working principle of today's large-scale bundled launch vehicles.

These things opened their eyes wide, as if once they succeeded, the whole world would be the Tang Dynasty.

However, the reason why Li Qing didn't tell them all these things before was because he knew that even if there was gunpowder and even if he knew about how those weapons were made, these weapons should never be able to play a decisive role at the beginning.

Because in the Song Dynasty and Ming Dynasty in their previous lives, although gunpowder had been invented and developed quite well, the protagonists in the real war were still cold weapons, otherwise the Song Dynasty would not have been destroyed by the Mongols in the end.

In the Song Dynasty in his previous life, the gunpowder did invent gunpowder, but at that time, the gunpowder was generally used as fireworks, so if gunpowder was made into military supplies, it was actually impossible to stop the Mongols from attacking at that time. So although the Song Dynasty invented gunpowder at that time, the strength of the firearm was not particularly powerful, and it was impossible to pose a particularly great threat to the Mongolian cavalry at that time, so it could not be used to deal with the Mongolian cavalry.

An example that Li Qing, a more simple one, was that in the Qing Dynasty in his previous life, the firearms actually developed to a very good level.

However, when it was used to deal with the invaders at that time, cold weapons were used, not firearms, because people at that time did not use firearms, so they would use more convenient things.

The same was true for the Song Dynasty. Although gunpowder was invented at that time, because gunpowder was not as good as the cold weapons they often used, they would definitely choose weapons that made them feel that they had a greater chance of winning, rather than weapons that they were unfamiliar with. What's more, gunpowder was not that threatening, so this is one of the reasons why the Song Dynasty invented gunpowder and did not use them to deal with Mongolian cavalry.

From the Song Dynasty to the Qing Dynasty, there were no things that China had used to using for so many years in the previous life. If Li Qing forcibly joined the military camp in this era, it would not only cause many problems because of immaturity in technology, but also completely possible that the combat effectiveness of the soldiers of the Tang Dynasty would not increase but decline.

Li Yi has been analyzing these problems in recent years and recalling them. At this time, he had basically discovered that the dynasties in his previous life still failed after using firearms, not because the firearms were not good, but because of their own problems.

For example, the defeat of the Song Dynasty to the Mongols was directly related to the Song Dynasty's policies. At that time, the Song Dynasty implemented a policy of gentleness to the outside world and suppressed military generals at home. Although the gunpowder of the Song Dynasty was not very pure, if it could be used properly, it would be enough to shock the Mongolian cavalry. However, the Song Dynasty did not popularize gunpowder in the army at all, and most soldiers still used swords to face the Mongolian cavalry.

The soldiers of the Song Dynasty at that time seemed stupid and heavy, and were inflexible in combat.

The gunpowder of the Song Dynasty played a major role in Diaoyu City, which also made the Mongolian army frightened. At that time, the Southern Song Dynasty was only invaded and the remaining half of the country was still unable to be defeated by the Mongolian army attacking Diaoyu City. At this time, the Southern Song Dynasty did not want to restore the country and vigorously develop gunpowder, but was in a state of sensuality and lost its last chance.

So when analyzing the Song Dynasty, Li Qing discovered that from these things, we can see that the Song Dynasty was also very powerful and its weapons were more advanced.

But the reason why they could not beat the Mongols was because their tradition was to suppress military generals blindly. If they value Yue Fei and others, there would be no crisis of national destruction. The Song Dynasty simply did not know how to be vigilant in times of peace, but only knew how to value culture but not martial arts, which eventually led to a crushing defeat. These were all things that Li Yan had to take as a warning.

At that time, the enemy Mongolian cavalry of the Song Dynasty paid great attention to combat skills and often used the tactics of surrounding and pretending to retreat to the enemy. This made them very mobile and could raid the enemy to achieve unexpected results. In addition, Mongolian cavalry often combined arrow rain with guerrilla warfare, which could enhance their combat capabilities.

This made Li Bai think of many things. It is definitely not possible to have a firearm alone. On the basis of proficient use, he also needs to tailor some combat skills for the army equipped with firearms, so that the role of this weapon can be maximized.

In fact, in the history of previous lives, there were not all those who valued culture and neglected military affairs like the Song Dynasty. In fact, the Ming Dynasty was not cowardly at all. Instead, it was the toughest among all dynasties. Their use of firearms actually reached a good level, but the result was not very good.

When the Ming Dynasty was founded in its previous life, the military situation was very serious, and Zhu Yuanzhang continued to take various effective measures to develop weapons manufacturing. In the early Ming Dynasty, the development of muskets reached its peak and was still in a leading position in the world at that time.

However, the Ming Dynasty had strict control over the manufacturing and use of firearms, and local governments were not allowed to manufacture without authorization, and individual development was strictly prohibited, which restricted the innovation of firearms.

As a result, the handguns that were established during the Yongle period did not have major innovations or breakthroughs until the introduction of the Folang machine and the Matchrope gun during the Jiajing period. Therefore, when the Folang machine was introduced in the early years of Jiajing, the Ming court discovered that the muskets were lagging behind, and immediately imitated and restructured them, and at the same time innovated the traditional muskets. Therefore, until the Ming Dynasty fell, the gap between its firearms and the West was actually very small.

After the war between Ningyuan and Ningjin was hit, the Qing Dynasty, which was invaded in the late Ming Dynasty, was determined to learn the Han firearm manufacturing technology. After entering the pass, they confronted the Southern Ming Dynasty, both sides created a large number of firearms to fight. From the end of Shunzhi and the middle of Kangxi in the Qing Dynasty, the national unified war was basically over, and the situation in various places stabilized, and firearm manufacturing gradually decreased. From the Yongzheng period, the firearm manufacturing industry began to decline. Until before the Opium War, China's firearm manufacturing technology level had lagged behind Western countries for more than two hundred years, resulting in a complete passive beating in the war.

These are all painful lessons that history has brought to Li Neng. Li Neng would never allow such a thing to happen in the Tang Dynasty under his rule, so he had to find a suitable time to tell it out.
