Fisherman's Song Dynasty

Listening to the sound of gongs and drums, listening to the sound of talking, Xu Zizhen immediately understood that what Zhao Gou wanted to listen to was not the details, but an explanation for himself.

He had no choice but to agree, first let Gao Chong send his wives home, and then follow Zhao Gou through the crowd back into the city. As for Mu Dongbai who was "watching a play", let him hang on first. Well, anyway, Wushu is only retreating temporarily, and the good show is yet to come.

Zhao Gou chose to drink in the inner hall of the magistrate's yamen. The food and drink were not ready yet, and news came that King Kaiping and Lord Zhang Shuye had returned. None of the two raiders were wiped out.

The two veterans, Gao and Zhang, came to see Zhao Gou excitedly with blood all over their bodies. After explaining the battle situation, they all praised Xu Zizhen. The two anticipating enemy planes were all thanks to Xu Zizhen's big black ball.

The Great Song Dynasty has been weak for a long time, and now it is less than half of the country. If you lose a game, you don’t know how much money you will lose. The two veterans are so loyal. The great victory reduced the creases on their faces by more than a dozen.

With a smile on his face, Zhao Gou comforted them with a few words, and then he picked up the teacup. The two veterans retreated with winks. In their opinion, His Royal Highness King Kang wanted to discuss secret military affairs with Xu Zizhen. No matter how senior they are, it would be inconvenient for them participate.

A few side dishes and two jugs of wine were placed on Huanghuali's small round table. Zhao Gou hadn't yet developed into the An Yi Emperor hiding in Lin'an, but was still a passionate young man full of ambitions, but he was a little stingy. It really is a small drink to say that it is a small drink.

Xu Zizhen didn't pay attention to these, but was secretly thinking about how to explain it. If it was half a year ago or earlier, he might have told the whole story without reservation, but now, he has to think carefully.

Zhao Gou poured him a full glass of wine himself, and raised his glass with a smile on his face: "Zizhen, thanks to you today, the [-] Jinren army was retreated. I respect you for this glass."

Xu Zizhen picked up his wine glass and said with a smile: "Qi Ye, you said that this word of honor slapped me in the face, it's better to be simpler, let's go together." After speaking, he raised his neck and drank cleanly.

A trace of obvious displeasure flashed in Zhao Gou's eyes, but he concealed it very well, and it disappeared quickly. Then he smiled, but he didn't finish the wine, he only took a sip.

Xu Zizhen was drinking, but he was looking at him from the corner of his eye through the rim of the wine glass. He caught the fleeting change in Zhao Gou's eyes, which made him feel a little bit moved. Sure enough, today is different from the past, Zhao Gou He is no longer the easy-going and friendly Qiye before. After going through so many things and becoming the Marshal of Yingtian Zhifu, his state of mind has obviously changed. Now he has begun to faintly have the temperament of a superior up.

"Okay, there are no outsiders here, let's talk about it." 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 is nothing to say about the cannon and crossbow. They were made for the siege soldiers of Wushu. It’s just a change on the gun rocket, but the black ball is a bit particular.”

As he spoke, he drew a rough shape on the paper, which looked like a pot, with a slender neck protruding from a big belly, and a handle that could be shaken beside the big belly.

"The ball is made of sheepskin, polished and tanned, and then soaked in oil. There is this thing under it, which is filled with black fire oil from Tubo. The fire is lit on the spout, and the handle is shaken to suck the oil out. It will keep burning, the heat will be steaming, and the big ball will fly into the sky, and then it will be tied with a rope, and it will become the thing you see now."

After Xu Zizhen explained Zhao Gou, he understood: "Could it be that the Kongming Lantern was changed?"

"Uh... that's pretty much what it means." Xu Zizhen didn't bother to explain, Kongming Lanterns are Kongming Lanterns, the concept is a bit 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, and I don't understand 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 is the big fireball device at the top of the city that can shoot far away in a parabola.

"Look, Seventh Master, this thing looks scary, but it's actually worthless. It's full of water, and there's firewood under it, and then..."

Xu Zizhen tried his best to explain the principle of the steam engine in a simple and easy-to-understand manner. In fact, he only knew the general idea, because he always failed in physics when he was in school. Now he can make the steam engine thanks to Du Jin and other friends who have been thinking about it day and night. For the experiment, he actually only provided a concept.

Zhao Gou frowned slightly, and listened very carefully, but it could be seen that he was completely in the fog.

"You mean, with such a long pole, there is a heavy object on the end of the pole, and the steam lifts him up, and then bounces him back when the brake is released. Is that true?"

Xu Zizhen said: "It's almost the same, that's what it means."

Zhao Gou nodded again: "How did the explosion outside the city happen? Did you dig a tunnel and bury gunpowder first?"

Speaking of this, Xu Zizhen is full of tears. In order to avoid the intelligence network of Jin Ren, these tunnels were dug together by him and Wen Baer. Apart from the two of them, there are only a few students from the science and engineering department that he trusts to help. Even relying on Wen Baer's professional touch tools and heaven-defying level to transport the earth, it took more than half a month to complete the work, which made them tired.

Zhao Gou guessed right, it was indeed a tunnel with gunpowder, but it was just digging dozens of passages criss-crossing like a chessboard underground, and then placed explosives at those intersections, and connected them all with fuzes. Keep ventilation, otherwise the fuze will be extinguished due to lack of oxygen before it is half fired, so a dozen vents were tunneled. The ground is only covered with a net made of bamboo strips, just to prevent hares and rats from falling in.

This mechanism was inspired by Xu Zizhen when he was at Xu Mo's house. The old Xu's medicine was placed in the ground. This is how it was done to keep it dry and ventilated. It was only changed to be used by Xu Zizhen to fight wars, and the effect was surprisingly good.

Wu Shu became more confident, so he didn't send anyone to check in the forest, but he suffered a big loss, almost all of the 3000 people disappeared.

After listening to Xu Zizhen explain everything, Zhao Gou nodded for the third time, and said with a smile: "Zizhen is indeed a genius with unparalleled wisdom and talent. Could it be that you are really an emissary sent by heaven?"

Xu Zizhen laughed, and was about to follow these words to make two jokes, but Zhao Gou said again: "Zizhen, there are dozens of young people in my house, all of whom are talented and intelligent. They also learn from your gunpowder mechanism?"

Zhao Gou had a gentle and friendly smile on his face, but Xu Zizhen couldn't help but feel a chill in his heart.
