Physician of the Song Dynasty: Zhang Kai and Li Qingzhao have a private life-long contract

"gunpowder!"

Baiguan was stunned, and suddenly felt humiliated as if he was being teased by Fan Zheng.

Gunpowder was not uncommon in the Song Dynasty. Some military even made gunpowder into weapons. However, the power of gunpowder became a joke in the Song Dynasty. The power of gunpowder weapons was extremely weak. Basically, it only produced light and smoke, and it was okay to make some big noise. , the lethality is just a scumbag, it looks good but useless.

Fan Zheng shook his head and said: "Gunpowder doctors are also involved. It can cure sores, kill insects, ward off dampness, plague, etc. Gunpowder weapons are not powerful because you use them incorrectly."

"Wrong usage?"

The ministers were in an uproar.

A trace of contempt flashed in Meng Yuan's eyes: "Then according to Fan Taicheng's words, how should gunpowder be used?"

Fan Zheng sneered: "The power of gunpowder has only one power from beginning to end, and that is explosion! But the military uses it to produce light and smoke. It is like picking up sesame seeds and losing the watermelon."

"explode?"

The officials frowned. If Fan Zheng hadn't contributed the bastion and divine arm crossbow just now, they wouldn't want to listen to Fan Zheng's nonsense.

And what's the use of explosions? It's like firecrackers that make music when heard. They have no power at all.

Fan Zhengzheng said: "Everyone knows that a firecracker as thick as a thumb can resound hundreds of steps, and a firecracker as thick as an arm can hurt people. It can be seen that the more and denser the gunpowder, the greater its power. If it is counted Kilograms of gunpowder, dozens of kilograms of gunpowder, or even hundreds of kilograms of gunpowder, doctors treated people who survived an explosion in a folk firecracker workshop. Their houses were destroyed, several people died, and more than ten people were injured."

Zhang Dun nodded in agreement: "There are indeed frequent rumors of gunpowder workshop crashes among the people."

"What does this have to do with defending Pingxia City?" Taiwei Meng Yuan frowned.

Fan Zheng took a deep breath and said: "Since you all know that Fan is a doctor, you should understand that a doctor not only knows how to save people, but also knows how to kill! When I saw the tragic situation of the survivors of the gunpowder explosion, Fan knew Gunpowder is a deadly weapon."

"A unique weapon? Fan Taicheng is exaggerating too much!" Zhang Dun didn't believe it at all.

Fan Zheng solemnly said: "Weapons in the world are all made of steel. If you want to double the power of gunpowder, you must fuse gunpowder with iron tools. Only by intertwining iron and fire can gunpowder become a unique weapon."

"The fusion of gunpowder and iron?" The ministers frowned.

"An arm-thick firecracker explosion is enough to hurt someone. What if we replace the bamboo tube with an iron tube?" Fan Zheng asked rhetorically.

"The gunpowder for arm-thick firecrackers is limited. What if the quantity of gunpowder is increased to five kilograms, ten kilograms, or even dozens of kilograms and packed into an iron cylinder?"

"If we shrink the mouth of the iron tube to look like an iron can, once it explodes, the iron shell will burst like a bamboo tube and penetrate the iron armor."

"We can even deliberately cast the iron shell into a checkered shape, so that the iron shell can be shattered more thoroughly and more lethal, like thunder."

"Even if a weak scholar only needs to light the fuse and detonate the iron gunpowder, even the Xixia Iron Kite will not be able to escape this disaster."

..............................

Fan Zheng explained one by one his conception of the Thunderous Thunder in the late Song Dynasty.

Taiwei Meng Yuan's face suddenly became solemn, because he had been exposed to gunpowder weapons and knew that what Fan Zheng said was not impossible.

"Is gunpowder really so powerful?" Zhao Xu looked at the energetic Fan Zheng and asked in surprise.

"The officials will know after a try!" Fan Zhengxin said.

How could the Forbidden Army camp be without gunpowder? At that moment, Meng Yuan gave an order, and soon, a large amount of black gunpowder was delivered to Fan Zheng.

Fan Zheng stepped forward, carefully inspected the black gunpowder, and couldn't help but nodded. The black gunpowder of the Song Dynasty was close to the perfect proportion formula, enough for military use.

"Fan Taicheng, wait a minute. The iron cans you need are being smelted by the craftsmen in the army and will be delivered to you soon," Meng Yuandao said.

There is no shortage of craftsmen in the Forbidden Army, let alone simple smelting of thin-skinned iron cans. "

"Every three steps, I'm going to place a dummy wearing armor."

Fan Zheng nodded, and took advantage of this time to command the Imperial Army to rearrange the training ground where the Divine Arm Crossbow had been.

Meng Yuan waved his hand, and the forbidden troops moved quickly.

After a test site full of dummies was set up, the iron cans were delivered.

Looking at the iron can in front of him that had just been smelted and had an uneven appearance, it was obviously the work of the craftsmen in the greatest hurry. However, Fan Zheng did not dislike it because this ugly iron can had perfectly met his requirements.

Fan Zheng solemnly took the tin can, filled it with the black powder prepared in advance, added a fuse, and finally sealed it solemnly. A simple but powerful earth bomb was completed.

Fan Zheng stepped forward, placed the soil bomb in the center of the test site filled with dummies, connected the long fuse, and was about to ignite it when he suddenly saw a crowd of emperors and ministers waiting eagerly.

"Please also ask the officials and all of you to retreat a hundred steps away!" Fan Zheng hurriedly advised.

"Hundred steps!"

Everyone was stunned and disapproved, thinking that Fan Zheng was just bluffing.

However, Fan Zheng insisted again and again, and all the monarchs and ministers retreated a hundred steps away.

Fan Zheng then turned around, took out the fire stick, lit the long fuse, and ran back crazily.

"Get down! Cover your ears and open your mouth!" Fan Zheng rushed to the side of Zhao Xu and others, yelling at everyone to follow suit.

However, Zhang Dun and other ministers did not take it seriously. They had already retreated a hundred steps, but they did not believe that gunpowder could still hurt them.

Seeing this, Fan Zheng only had time to pull Zhao Xu to bend down when a loud noise came from his ears.

"boom!"

The deafening sound resounded through the entire Forbidden Army camp. All the ministers felt a thunder ringing in their ears, which made their ears roar. Many old and weak ministers were even frightened and stumbled to the ground.

The ministers who remained standing did not laugh, but looked dull. Even though they were a hundred steps away, they still felt a strong threat.

The sharp-eyed minister had already seen the scene at the testing site. The dummy in armor was already staggering, and it was obvious that he had been seriously injured.

"Officials, please move and take a look." Fan Zheng looked at the shocked expressions of the ministers and couldn't help but said with satisfaction.

Zhao Xu's face was solemn, and he led the ministers back to the test site. He couldn't help but take a breath of cold air. All the dummies within twenty steps were seriously injured, all the dummies within ten steps fell down, and the dummies within five steps were seriously injured. The armor was directly penetrated by explosive fragments.

"This weapon cannot be resisted by human beings!" Taiwei Meng Yuan exclaimed.

"You can imagine, if Pingxia City has the danger of a fortress, the power of the divine arm crossbow, and the power of gunpowder, who can break it." Fan Zheng said proudly.

The ministers nodded involuntarily. Their attitude toward gunpowder had changed from disdain to shock to ecstasy. The emergence of powerful gunpowder weapons had evened the gap in military force between the Song Dynasty and Xixia.

No! The Song Dynasty, which controlled gunpowder, surpassed the Liao Xia in terms of force for the first time.

"What's the name of this weapon?" Zhao Xu said with a face that couldn't hide his surprise.

"This weapon is astonishingly powerful. It sounds like thunder, otherwise it is called Zhentianlei." Fan Zheng mentioned the name of Zhentianlei in later generations.

"With this artifact! Why should I, the Song Dynasty, be afraid of Xixia!" Zhang Dun said ecstatically.

The other ministers also nodded with concern. Just imagine if Xixia attacked Pingxia City on a large scale, Song soldiers gathered on the edges and corners, divine arms and crossbows were as dense as raindrops, and thunder fell from the sky one after another. Who in the world could defeat it.
