At this time, after getting the news of the emperor's visit, Shen Kuo and Su Song both surrounded him. Tang Xun said proudly www.biquge.info pen fun pavilion: "Your Majesty guessed accurately, this is the mother and daughter cannon." ”

Seeing Lu Chengqi walking forward in a daze, Su Song hurriedly waved away the apprentices who were about to operate the artillery. There was nothing else in Lu Chengqi's eyes, ******** pounced on the sub-cannon, gently stroked the slightly hot cannon body, and then picked up a sub-cannon to weigh it, with a look of fascination.

Shen Kuo was a little confused: "Your Majesty, what's wrong?" ”

Although Su Song was a little taciturn, he knew Lu Chengqi best: "Your Majesty is fascinated by this cannon!" ”

Tang Xun was puzzled: "This cannon has not been fired, how can Your Majesty judge that this is the best artillery?" ”

Shen Kuo understood that among the three, although Tang Xun was the oldest, he was devoted to research, and his human feelings were not as good as the other two. Shen Kuo pointed out and said: "Your Majesty has known for a long time, we must have tested it before inviting Your Majesty." ”

A smart person can give three examples. Tang Xun is not stupid, he just didn't think about it from this perspective for a while. "I see!" Tang Xun suddenly realized, and looked at Lu Chengqi, who was obsessed, and he understood it in his chest.

Lu Chengqizai carefully observed the sub-mother cannon, and then stood up reluctantly, ignoring the blackness of his hands, and said eagerly: "Quick, give me a shot!" ”

Su Song had been waiting for this sentence for a long time, glanced at Shen Kuo, and said, "Your Majesty, please move to the distant overlook house......

This overlook house is the stone house made of heavy stones. The deep foundation and thick walls, even if the muzzle of the cannon is turned, it is estimated that there are no dozens of cannons, and it will not be able to knock down such a stone house. In front of the stone house, a small window was opened so that you could observe the situation outside.

Lu Chengqi, under the leadership of the three of them, entered the stone house, and those apprentices dared to come to the side of the mother cannon. Looking at them from a distance, they looked cautious, and it seemed that they had experience. After all, black and gunpowder are very dangerous, very unstable flammable and explosive materials, and if there is not a single one, I am afraid that there will be no bones. It is not uncommon for the Ordnance Inspector to have a similar situation before, but fortunately, it was properly controlled and did not cause a chain reaction. It is precisely because of this that in the ordnance prison, iron smelting, black and gunpowder are stored, and they are placed at the east and west ends respectively. Fireworks are strictly prohibited within a radius of 100 meters from the warehouse where black and gunpowder are stored.

These apprentices have either witnessed the tragic situation or experienced it themselves, and they are all cautious. It is precisely because of this that Lu Chengqi is more assured. Black and gunpowder are not easy to control, and only rigorous can avoid wrong operation and irreparable consequences.

I saw that these apprentices were working together to clean the gun chamber, prepare the sub-cannon to prepare the sub-cannon, and adjust the height of the cannon shaft...... After everything is done, just wait for the order to launch.

Shen Kuo raised the small flag in his hand and waved it vigorously, and the apprentice in charge of lighting the fire immediately turned around and lit the fire when he saw it, and then the four apprentices all retreated several steps back. The lead glowed with orange-red fire, and everyone held their breath, only to hear the "sizzle" of the lead.

After the lead was pointed, there was a sudden "boom", and then after a while, there was an echo in the distance. And the recoil of the sub-mother cannon rebounded on the ground, and Lu Chengqi still felt the same shock as last time.

"It seems that the power of this sub-mother cannon is not bad!" Lu Chengqi said in his heart, and then subconsciously patted the dust on his body, these are the dust that fell on the roof because of the vibration.

"One more shot!" Lu Chengqi said in an unquestionable tone.

Shen Kuo did not hesitate, and hurriedly waved the small flag in his hand again. I saw that those apprentices did not hesitate and immediately began to prepare for the next shot. And Lu Chengqi silently counted the time in his heart from the beginning of their start: "One, two, three......"

After about half a minute, the apprentices were already loaded. Lu Chengqi was very excited, and said in his heart: "This sub-cannon, using the sub-cannon as a 'bullet', the loading speed is really much faster!" As soon as he turned this thought, there was another "boom", and another shot was fired.

"Booming ......"

Because of the proximity, the tremor was still very strong. The dust on the stone roof fell one after another. At this moment, whether you are an emperor or an official, your body is covered with dust. Lu Chengqi didn't care and said, "Shen Qing, should I go and find out how far the range is?" ”

Shen Kuo nodded and said, "Back to Your Majesty, it's true." ”

Lu Chengqi nodded and said, "Let's go test first." By the way, this is a solid bullet, right? ”

Su Song said: "That's right, this time I used a solid bullet. ”

"Then I tested before, how far can a solid bullet hit?" Lu Chengqi is most concerned about the issue of range, if the sub-mother cannon only has a range of one mile, it is not as good as a bed crossbow.

Tang Xun said: "Your Majesty, the range of this sub-mother cannon is beyond our expectations, and it can shoot eight miles away!" ”

Lu Chengqi was surprised, this is comparable to the range of the previous red-clothed cannon! The expression on his face was surprised, and he asked eagerly: "What about the flowering bomb, have you ever measured it?" ”

The three of them were silent at the same time, and none of them spoke. Lu Chengqi was a little confused: "What, haven't you tested it?" ”

Shen Kuo finally spoke: "Your Majesty, please forgive your sins!" We thought it would be very easy, but it wasn't easy to operate. When a cannonball is cast, either the body is too thick or too thin. The body of the bullet is too thick, and it can only be split into two halves or several petals; The bullet was too thin, and before it could hit a mile, it all spread out......"

Lu Chengqi was also silent, and Su Song followed closely and said, "However, after mastering the trick, the speed of casting has also accelerated. It's uneven, but it's not as good as it could be. If Your Majesty wants to see it, wait for them to measure the turn, and then fire a few more shots......"

Lu Chengqi nodded and said, "There is nothing difficult in the world, but I am afraid of people with hearts." Pay attention to the method, and it will always succeed. This flowering bomb is a sharp weapon to resist the Khitans, and it must not be given up! Even if the range is only two miles, you have to get it! ”

Lu Chengqi's resoluteness also infected the three of them. They are already very intelligent, and now they have experience, and when they are in the prime of life, they may be able to achieve much in the future!

Sighing, Lu Chengqi continued: "If only the three of you can build artillery in Dashun, I am still very worried. Now it seems that the students of Royal Roads University have also become talents. If a country has no inheritors, no matter how good the technology is, it will be lost one day. You remember, what is passed on to men and not to women, and not to be passed on to masters and apprentices, these are all childish practices. What I want to do is that Chinese civilization will be passed on forever, and it must be ...... by Royal Roads University" (To be continued. )
