Listening to the gongs and drums and the voices, Xu Zizhen immediately understood that what Zhao Gou wanted to hear was not the details, but to give him an explanation himself.
He had no choice but to agree, first let Gao Chong send his lovely wives home, and then follow Zhao Gou through the crowd back into the city. As for Mu Dongbai who was "watching the show", he let him hang up first
Well, anyway, Wu Shu is only temporarily withdrawing his troops, and the good show is yet to come.
Zhao Gou chose to have a drink in the inner hall of the prefect's Yamen. The food and wine were not ready yet. Another news came that King Kaiping and Mr. Zhang Shuye were back. The two were familiar with each other and fought a beautiful ambush. The Jin man once again
The two groups of troops who made the surprise attack were completely wiped out without leaving a trace.
The two veterans, Gao and Zhang, came to see Zhao Gou excitedly with blood all over their bodies. After explaining the situation of the battle, they all began to praise Xu Zizhen. Zhang Shuye, who had previously had a strong opinion of Xu Zizhen, even praised him without hesitation. After all, this
In both games, Xu Zizhen's big black ball was responsible for predicting the enemy.
The Song Dynasty has been weak for a long time, and now it has lost half of its country. It loses every battle and loses an unknown amount of money and land. The two veteran generals are loyal and have suffered for so many days, but today, in a short period of time, two
A great victory, which made them so happy that the wrinkles on their faces were reduced by a dozen.
Zhao Gou smiled and comforted them with a few words and then took up the tea cup. The two veteran generals withdrew with a wink. In their opinion, His Highness Prince Kang wanted to discuss secret military affairs with Xu Zizhen. It was not convenient for them no matter how senior they were.
participate.
A few side dishes were placed on the small round table of Huanghuali, and there were also two bottles of wine. Zhao Gou had not yet developed into the Anyi Emperor who was hiding in Lin'an and living an ignoble life. He was still a passionate young man full of ambitions, but he was a little stingy.
If you say you have a drink, you will indeed have a drink.
Xu Zizhen didn't pay attention to this, but secretly thought about how to explain it. If it was half a year ago or earlier, he might have told everything without reservation, but now, he had to think carefully about it.
Zhao Gou personally poured him a full glass of wine, with a smile on his face, and raised the glass: "Zizhen, thanks to you today, we were able to retreat the Jin army of 100,000 people. I toast you with this glass."
Xu Zizhen picked up the wine glass and said with a smile: "Master Qi, you said this word of respect is going to slap me in the face. It's better to keep it simple and let one of us go." After saying that, he raised his neck and drank it all.
A trace of obvious displeasure flashed in Zhao Gou's eyes, but he concealed it well and quickly disappeared. Then he also smiled, but he didn't finish the drink and only took a sip.
Xu Zizhen was drinking, but he kept looking at him through the edge of the wine glass from the corner of his eye. He caught the fleeting change in Zhao Gou's eyes, which made his heart move slightly. Sure enough, today is different from the past, Zhao Gou
He is no longer the easy-going and friendly Qi Ye before. After experiencing so many things and taking up the post of Marshal of the Yingtian Prefecture, his mood has obviously changed. Now he has begun to have the temperament of a superior.
.
"Okay, there are no outsiders here, let's talk." Zhao Gou put down the wine glass and looked at him with burning eyes.
Xu Zizhen thought for a while, ran to the desk next to him, took a piece of paper, took out a charcoal pen and said: "There's nothing to say about the cannon and crossbow. They were made against Wu Shu's siege troops. They were just used under our original fire.
The gun and rocket are just modified, but the black ball is a bit more particular."
As he spoke, he drew a rough shape on the paper. It looked like a pot, with a slender neck protruding from a big belly, and a swinging handle on the side of the big belly.
"The ball is sewn from sheepskin, polished and soaked in oil. There is this thing underneath. It is filled with black fire oil brought from Tibet. Light a fire on the spout, shake the handle to suck out the oil, and the fire will
It will keep burning, the steam will steam, and the big ball will fly into the sky. Then tie it with a rope, and it will become what you see now."
After Xu Zizhen explained, Zhao Gou understood: "Is this a modification of the Kongming Lantern?"
"Uh...that's pretty much what it means." Xu Zizhen didn't bother to explain. The Kongming Lantern is just the Kongming Lantern. The concept is somewhat similar.
Zhao Gou asked again: "Then how is your telescope made?"
This is a difficult problem. Xu Zizhen scratched his head for a long time and didn't know how to explain it. He could only say: "I learned this when I was a child in Nanyang. I can't explain the specific principle."
Zhao Gou nodded and didn't ask any further questions, just looked at him.
Xu Zizhen understood and drew a big belly thing on the paper. This was the big fireball device at the top of the city that could shoot far away in a parabola.
"Master Qi, look, this thing looks scary, but actually it's worthless. This big belly is filled with water, put firewood underneath, and then..."
Xu Zizhen tried his best to explain the principles of the steam engine in an easy-to-understand manner. In fact, he only knew a rough idea because he always failed in physics when he was in school. Now he can make the steam engine thanks to Du Jin and a group of friends who worked day and night.
Experiment, he actually only provided an idea.
Zhao Gou frowned slightly and listened carefully, but it was obvious that he was completely confused.
"You mean, with such a long pole, put a heavy object on the end of the pole, lift it up with steam, and then bounce it back when the brake is released. Is this the truth?"
Xu Zizhen said: "Inseparable, that's what it means."
Zhao Gou nodded again: "How did you do the explosion outside the city? Did you dig a tunnel and bury the gunpowder first?"
Talking about this Xu Zizhen was filled with tears. In order to avoid the Jin people's intelligence network, he and Wen Baer dug these tunnels together. Apart from the two of them, there were only a few science and engineering students he trusted to help.
Moving earthwork, even with Wen Baer's professional gold-touching tools and incredible skills, took more than half a month to complete, but the two of them were exhausted.
Zhao Gou guessed right. It was indeed a tunnel with gunpowder. It was just a matter of digging dozens of passages criss-crossing the ground like a chessboard. Then he placed explosives at those intersections and connected them all with fuses. In addition, there were also underground tunnels.
Keep it ventilated, otherwise the fuse will burn before it's halfway lit.
It must be extinguished due to lack of oxygen, so more than a dozen vents were built in the tunnel. In the sparse fruit forest that Wu Shu saw, the vents were just open on the ground, with only a net made of bamboo strips.
It's just a piece of paper to prevent rabbits, mice and the like from falling in.
This mechanism was inspired by Xu Zizhen when he was at Xu Mo's house. Old Xu's medicine was kept under the ground to keep it dry and ventilated. However, Xu Zizhen learned it and used it for fighting, and the effect was surprisingly good.
Wu Shu was a little more confident, so he didn't send anyone to inspect the forest. As a result, he suffered a huge loss, and almost all of his 23,000 people were lost.
After Zhao Gou listened to Xu Zizhen's explanation of everything, he nodded for the third time and said with a smile: "Zizhen is indeed a genius with unparalleled intelligence and scheming. Are you really an angel sent by God?"
Xu Zizhen laughed, and was about to make a joke with these words, when Zhao Gou said again: "Zizhen, there are dozens of young people in my house, all of them are talented and intelligent people. I wonder if you can teach them for me.
Are they also learning your gunpowder trap skills?"
Zhao Gou had a gentle and friendly smile on his face, but Xu Zizhen couldn't help but feel a chill in his heart.
