Lu Chengqi also knew that if he wanted to forge an artillery with excellent power, rate of fire, and movement ability all at once, it was a fool's dream. If you can build a cannon that can hit according to the principle of artillery, it is considered a great success.

It's just that the big black guy in front of him is too cold, right? Lu Chengqi couldn't help but complain in his heart, could this ugly artillery still have any good performance?

Glancing at Su Song and Tang Xun, who were eager to try, Lu Chengqi was silent, and made up his mind to observe the performance of such an ugly artillery first. Thinking of this, Lu Chengqi said: "Since Su Qing and Tang Qing both have strong confidence in this artillery, of course I want to have a glimpse. ”

Su Song and Tang Xun obtained the emperor's permission, and immediately recruited two apprentices and asked them to start loading black, gunpowder, and charcoal with very small particles, and then reloading the cannonballs. This charcoal is a combustible substance, so that it can be fully burned. Su Shi and Tang Xun learned from the loading of Hongxiang-style rifles, the smaller the charcoal, the more fully burned, and the greater the power of the artillery. After the two apprentices put the lead into the gun door, the front-loading smoothbore gun was reloaded.

After loading, raise the muzzle of the gun again, at an angle of about 30 degrees. After all this, Lu Chengqi estimated that it had taken almost a quarter of an hour. This may be due to the fact that the two apprentices are not proficient in loading, and Lu Chengqi estimates that if they are proficient, the loading time will be reduced to about seven or eight minutes.

Even Lu Chengqi, who is not a military fan, knows that if he wants to hit with a shot without a ruler, it is a big luck. Lu Chengqi, who was far away, found that the shells used in this artillery were actually solid shells. Although this solid bullet shoots farther, its lethality is only a straight line. If a solid shell hits the ground, it may bounce off and cause secondary damage. If it hits a stony ground, the broken stone is also one of the lethal powers. But in general, the lethality is still too low, far inferior to the flowering bomb. But in these years, if you want to make a flower bomb, it is a fantasy, there is no thunder, mercury, and no systematic chemical knowledge, so it is not easy to make a flower bomb!

By the time the two apprentices had finished everything and applied to fire, a quarter of an hour had passed, almost a quarter of an hour. Su Song got the news from the apprentice, and then asked Lu Chengqi, Lu Chengqi nodded, and Su Song shouted loudly: "Ignite!" ”

The cannon stuck in the sandbag had no other fixtures, and the two apprentices lit the fuse, spread their feet and ran back. Even if they knew, the performance of this gun was quite superior. However, during the experiment, several apprentices were injured due to operation errors, but fortunately the injuries were not serious. The lessons of the past made these apprentices frightened birds, and every time they lit the fire, they had to subconsciously run backwards.

They are also clever enough to make the lead longer, so that they will have more time to retreat. After these apprentices ran to Su Song's side, inside this stone house, the cannon finally burned out the lead.

"Bang !!"

There was a loud bang, like a thunderbolt on a sunny day, and Lu Chengqi felt the ground shake a little, and a cloud of dust fell above his head. At this moment, Lu Chengqi almost thought that he had come to the battlefield of the next generation.

This loud bang came and went quickly. Lu Chengqi estimated that it took almost two minutes from the ignition of the lead to the firing of the artillery. And if you look at the cannon that has fired a shell, it is fortunate that it is stuck in the sandbag and has not moved.

Seeing this, Lu Chengqi smiled at the two apprentices and said, "What, are you afraid of artillery?" ”

The two apprentices were so frightened that they knelt on the ground and begged for mercy again and again: "Holy spare your life, Holy spare your life, little one...... Small...... I'm very afraid of ignition, and I've hurt a lot of people in the past experiments......"

Su Song listened, and said with a calm face: "That's just a small injury, just cultivate a little and apply a gold sore medicine." Besides, it was an experimental artillery, and it was normal for the performance to be unstable, and if there were no major problems, it meant that the way was right. This artillery uses the latest casting technology, the barrel is long, the pipe wall is very thick, and it is gradually thickened from the muzzle to the tail of the gun, which not only greatly increases the power, but also has a good safety performance, why are you still afraid of it? ”

Lu Chengqi felt funny when he saw Su Song's hatred of iron not becoming steel, and said: "This is human nature, Su Qing should not be angry." Besides, didn't I and all of you stay in this stone house? Safety comes first, and there's nothing wrong with what they're doing. Human life is precious, and ants still spare their lives, let alone them? Arise, not only are you innocent, but it is a great achievement to test the artillery! ”

Hearing the little emperor's words of forgiveness, the two apprentices thanked them and kowtowed. Lu Chengqi sighed: "I have often said that black and gunpowder are very difficult to control. If you don't pay attention, you will die. If black and gunpowder are developed again, they will turn into yellow and gunpowder, and the power will be even more earth-shattering, and the slightest negligence will kill you. I said ugly things ahead, you are the most high-end talents in Dashun, and I don't want you to die because you don't pay attention......"

At this time, a person behind him said: "Yes, although the minister has only been exposed to this black and gunpowder for a while, the fierceness of this thing is far greater than that of a tiger. His Majesty said that artillery is an artifact of war, and the minister didn't believe it before, but now he believes it. Such a loud noise is beyond the power of heaven and earth. ”

Lu Chengqi looked back and saw that the person who spoke stepped into the stone house, it was Shen Kuo. At a time when artillery research was nearing success, he was still teaching at Royal Roads University. It's not that he doesn't want to participate in the casting of cannons, but he knows that at that time, the artillery has already entered the experimental stage, and if he joins at this moment, isn't it a credit grab!

Even if Shen Kuo is stunned and doesn't understand human feelings, he can't do such a thing, and he has a guilty conscience. Today, when he heard about the finalized test firing of artillery, he rushed from Royal Roads University. Before he arrived at the ordnance superintendent's test range, he heard this loud noise, which almost paralyzed him to the ground. finally stabilized his mind and rushed to the stone house at the test shooting site, but he heard Lu Chengqi emphasizing the safety issue, and couldn't help but second.

Shen Kuo interjected, Lu Chengqi didn't think it was a pestle, but asked: "Shen Qing is also here, just right, let's go with me to see how this artillery performs." ”

Let the two apprentices walk in front, pour water into the cannon chamber, extinguish the fire star, and then tie a dry cloth to the stick and reach into the cannon chamber to dry, before daring to invite the emperor to the artillery. The black, gunpowder is unstable, and if there is a spark, it may cause an explosion.

Lu Chengyun lightly touched the barrel with his hand, and found that the temperature of the barrel after cleaning was not high, and it looked warm. It seems that this is indeed a cannon body made of fine steel, which absorbs heat quickly and dissipates heat quickly. At this temperature, there is probably no problem with firing more than ten cannons in a row.

Seeing Lu Chengqi reaching out to touch the barrel of the cannon, Tang Xun was so frightened that he shouted: "Your Majesty, no!" "It's just that Lu Chengqi is so stupid, just touch it lightly and feel the temperature of the barrel, do you have to burn yourself to be willing?

Seeing that Lu Chengqi was fine, Tang Xun was relieved, and said earnestly: "Your Majesty, after this artillery fires shells, the barrel will be very hot, Your Majesty should not do this dangerous act again in the future." If it is burned, it is difficult to escape the blame for the death of the minister! ”
