On the bed in the laboratory, a middle-aged man was lying on the bed, his hands and feet were tied, the whole person was extremely weak, coughing from time to time, and even coughing up blood. No matter which doctor reads it, the conclusion will be surprisingly consistent, that is, prepare for the future!

In this era, even Li Shizhen dared to accommodate such a patient, and no one else had a role.

Li Shizhen came to the man's side, looked at the man lying on the bed, and said with a smile: "You will be fine soon, don't worry." ”

While speaking, Li Shizhen took the medicine he had prepared, this man was pneumonia, and he was already very sick, so he could basically declare that there was no way to save him. Carefully picked up a syringe, the expression on Li Shizhen's face was very careful, this syringe is a good thing!

The needle body made of glass, and the pillow is made of copper, of course, compared to the needles of later generations, this needle is much thicker.

But even if it is such a rough syringe, it is an existence that Li Shizhen needs to be particularly careful, because it is made for Li Shizhen by the skilled craftsmen of the Ming Dynasty.

When making this syringe, it was really a waste of effort, and the manufacturing process can be described in one sentence, that is, it has been made! It doesn't matter if you fail, if you come, if you fail, you will come again, anyway, it is when you succeed and when you will count, regardless of the cost.

Li Shizhen skillfully pulled out the reddening potion, and then aimed the thick needle at the man's buttocks.

took the alcohol cotton and wiped it on the other party's buttocks, and Li Shizhen pierced his thick needle into the other party's buttocks.

As the needle penetrated, the man's body tensed suddenly, and he let out a howl of pain. It's just that Li Shizhen didn't react at all, the other party's hands and feet were tied, and there was no way to struggle at all. Seeing that the other party's muscles were tense, Li Shizhen also reached out and patted the opponent's ass a few times, and then slowly pushed the needle.

When the pale red elixir entered the other party's body, Li Shizhen breathed a sigh of relief and took a piece of alcohol cotton and held it down for the other party.

After doing all this, Li Shizhen breathed a sigh of relief, and all that was left was to observe.

When Li Shizhen was crazy about experiments, Daming and other people were also experimenting, you must know that the Ming economy has developed greatly in recent years, the imperial court has money, the local government has money, and all kinds of needs have emerged in an endless stream, which has made all kinds of inventions of the Ming Dynasty grow exponentially, and all kinds of strange things have been invented.

It's just that there are very few things that are useful in this kind of invention, and of course, there are very few things that are useful and innovative.

Armament Division.

Since participating in the Invincible Cannon Project, Xu Guangqi has swept away his previous scholarly style and completely become a scientific research worker. At this time, Xu Guangqi was wearing a white coat, but there were black oil stains everywhere, and he didn't know what he was rubbing in some places, which looked very dirty.

However, none of the people present paid attention to this, and their attention was all on what was in front of them.

This is a cannon, you say it's a cannon, its muzzle is not thick, and it is the thickness of the bowl mouth, but the barrel is very long, half a person high. The copper barrel looked more like a barrel, and there was an iron plate on the ground, and the cannon looked unusually rudimentary.

But everyone present knew that this cannon was made by the most cutting-edge technology of the Ming Dynasty.

Next to this cannon was a wooden box with a freshly made cannonball, which, unlike the previous one, was an oval-shaped cannonball, with a tail in the back. The five shells in the box looked inconspicuous, but everyone present knew what a treasure this thing was.

For these shells, the Armament Division has invested a lot of manpower and material resources, although it is expensive to build now and cannot be mass-produced, but everyone knows the meaning of these five shells.

In fact, if it is a person from later generations, you will know at a glance that this thing is not a mortar?

Xu Guangqi breathed a sigh of relief, this thing took him a lot of effort, once it succeeded, it would represent a qualitative leap. Although its cost is high, although it still has many problems, but the meaning it represents is epoch-making, now take it to try, if it becomes, it means that this direction is right.

"Come on, try the gun!" Xu Guangqi looked at the cannon in front of him and spoke, his expression was unprecedentedly dignified.

The danger of testing the artillery, especially the experiment of this new cannon, is very high, if it can't be hit and explodes on the spot, it is very dangerous, and the person who fires the cannon will not even have time to run, and will be directly blown up next to the new cannon. No one dares to be careless at this time, and Xu Guangqi is the same.

The new cannon was placed in a pit surrounded by bags of sand, and after the test the gun, the experimenter would turn over to the other side of the bag containing the sand.

A pit was also dug there, and the testers would lie down in it to avoid damage as much as possible.

With Xu Guangqi's words, a test gunner wearing light armor came to the side of the new cannon, holding a new cannonball in his hand. With a sigh of relief, he aimed the shell at the barrel of the new cannon. Everyone present watched this scene with bated breath, no one spoke, and they didn't even dare to breathe.

As soon as the tester's hand was released, the shell fell into the barrel, and the tester hurriedly flipped on its side to the other side of the sandbag.

It's just that as soon as he reacted, a voice "ton" sounded behind him, and then the shell shot out of the new cannon and flew directly to the test site not far away. A violent explosion followed, sending smoke and dust and dirt and rocks flying.

"Success, success!"

The scene suddenly resounded with cheers, even Xu Guangqi, who was usually steady, jumped up excitedly at this time, countless people screamed loudly, and countless people burst into tears. This is more than a thousand days and nights of hard work, this is the result of the hard work of countless people, and it really succeeded!

The success of such a cannon represents not only the success of the artillery, but also the success of the cannonball.

The success of metal fixed artillery shells, for the Armament Division, they know too well what this means.

"Tonight, wine and meat are not taboo, we are not drunk and do not return!" Xu Guangqi laughed and shouted, followed by more excited shouts.

Forbidden City, Wenhua Palace.

At the end of the year, there are a lot of things in the imperial court, and Zhu Yijun is also very busy these days, of course, this is also related to one thing being turned out, this matter is Zhu Yijun's ancestor worship. The last time the ministers wrote the letter, Zhu Yijun blocked it back with the unfinished grassland, and this time the ministers once again mentioned the old thing.
