There was a booming explosion, and someone climbed up from the ground in disgrace. His face showed the joy of surviving the disaster. He turned around and looked at the large gap that was opened behind him.
Just a little bit, just a little bit closer. If he had run any slower, he might have lost his arms and legs by now.
"It's okay!"
Zhao Kang ran up to him and lifted him up. The worker responsible for lighting the bomb quickly said: "It's okay, sir, who the hell did grandma do this? It exploded so fast!"
There was still some fear as he spoke.
Zhao Kang frowned: "It seems that it is not just the length of the lead that affects the explosion time."
He raised his head and thought about the people around him and said: "Don't conduct test explosions yet."
After saying that, he walked forward, and Xiao Linglong followed, and the two of them walked to the explosion site.
In order to test the power of the explosion, they chose to light the bombs on flat ground, and then added some heavy shielding around them to try to simulate the situation of bombs falling on the battlefield.
What I saw now was that the radius of the explosion was about three meters, and all the wooden boards, rocks and other objects used to block it were blown to pieces.
This is thanks to the bombs Zhao Kang had people make, each of which was filled with about two kilograms of gunpowder.
Xiao Linglong exclaimed: "This kind of destructive power is already comparable to the full blow of a fifth-grade peak warrior."
"Almost, the explosion power has achieved the effect we wanted, but the explosion time is difficult to control." Zhao Kang squinted his eyes.
Her Majesty the Empress asked curiously: "Isn't it enough to be able to control the power of explosions?"
"Fool, if you can't accurately control the time of the explosion, when the shell explodes in the barrel, we will be the ones injured at that time."
Zhao Kang laughed: "The bomb's explosion time, power, and the bearing capacity of the barrel must be consistent to ensure that every bomb and every cannon are exactly the same, so as to minimize the possibility of accidents.
This is standardization. Without standardization, even if you build a cannon, it will be in vain."
Xiao Linglong stuck out her tongue: "I don't quite understand."
"Slowly you will know." Zhao Kang laughed, and then asked someone to arrange another test explosion.
It had been seven or eight days since he led people to make bombs and cannons. The bomb-making technology was almost mature, but it was still far from the standardization he mentioned.
When bomb No. 57 was tested, the recorder was a little surprised and shouted loudly: "No. 57, the explosion time is eighteen seconds!"
Everyone looked at Zhao Kang.
"Eighteen seconds, that's about it."
Zhao Kang was delighted: "Who made this bomb?"
"Tell me, sir, it's me!" A man ran out in a hurry.
Zhao Kang: "Go and get five more. If the explosion time of these five is the same, I will give you a bonus!"
"Master, please look at it, I remember the thickness of the projectiles for all the raw materials!"
The man chuckled and followed Zhao Kang's instructions to go down and tinker with bombs.
Zhao Kang and Xiao Linglong came to the artillery casting factory again. It was extremely hot here. The craftsmen waved their hammers, and the molten iron and forging never stopped for a moment. Several old blacksmiths also looked at the drawings in their hands to discuss how to do it.
The barrel of the gun that Zhao Kang said was cast.
After Zhao Kang looked at it twice, he took Xiao Linglong and left. Making a cannon is much harder than firing porcelain or something.
And it goes without saying that the first one that comes out will definitely not be used.
This thing requires failure to accumulate experience.
Not to mention the complicated process of rifling, the ancient artillery firing principle is to use the explosive force generated by the gunpowder filled in the barrel to push the bomb out.
The lack of rifling will lead to a lack of accuracy in striking. These are all problems that need to be overcome.
Zhao Kang didn't know much about this and could only rely on everyone to pool their wisdom.
The two of them were walking on the street. Counting the time, Zhang Long and the others should return, and then they could start training the new army.
At this time, a middle-aged man wearing a Confucian shirt came hurriedly behind him, "Zhao, Mr. Zhao."
Zhao Kang and Zhao Kang turned around. Looking at each other's clothes, they knew he was a teacher in the school. They smiled and asked, "What's wrong?"
"Mr. Zhao, my husband invites you to go to school." The man hurriedly saluted and said.
Zhao Kang and Xiao Linglong looked at each other. What would happen if Zhang Sheng invited him to school?
All the way to school.
Compared with the past, the school has obviously expanded in size. It is the time when school is over at noon, and the students are eating free lunch in the cafeteria.
In the teaching classroom, seeing Zhao Kang and Xiao Linglong arriving, Zhang Sheng quickly stood up and said, "I have met Your Majesty, the National Master."
"You're welcome, sir. Please take a seat."
Zhao Kang and Xiao Linglong both hurriedly avoided this ceremony. The three of them sat down and Zhao Kang asked, "Sir, what are your orders for me?"
"Don't dare."
Zhang Sheng said with a smile: "I really have something to discuss with the Imperial Preceptor and His Majesty. Do the Imperial Preceptors still remember what they said at the beginning about opening the Dragon Gate for the poor people in the world?"
"Don't dare forget."
Zhao Kang quickly sat up straight. This was indeed a major event and would involve the vital interests of many aristocratic families.
Even Xiao Linglong didn't dare to act rashly.
Zhang Sheng nodded: "That's good. It's such a national teacher. I have considered it. Now that our school in Yuanjiang County is on the right track and all work has been completed, we can consider setting up schools in other places to allow more
people can go to school.”
"But for today's scholars, studying this matter is all about gaining fame in the future."
Zhang Sheng said helplessly: "We now provide a place to study, but we cannot give you honors. Do you understand, Imperial Master?"
"Zhao Kang understands." Zhao Kang nodded.
What Zhang Sheng means is that now we can consider the reform of the imperial examination, but it is not that easy to take action.
First of all, the imperial examination quotas are monopolized in each of the five states of Qian State, and there are only so many places for each local examination.
All the local aristocratic families came together after consultation. Your family will go first this year, and mine will come next year.
In other words, before the cake was even baked, they had already figured out how to divide it.
Now Zhao Kang suddenly wants more people to come to the table to share the cake, how can they be happy?
Xiao Linglong on the side suddenly said: "It will be autumn soon."
Zhang Sheng nodded: "Yes, it is precisely because of this that I want to discuss with the Imperial Master whether we should take advantage of this autumn opportunity to allow all students in the world who are qualified to participate in the imperial examination."
"This matter needs to be carefully considered." Zhao Kang lowered his eyes and began to make calculations in his mind.
