Speaking of headless unveiling, the conversation of the drinkers in the audience became stronger. Each of them has been thrown into their homes by people, not only in their homes, but even in the Yamen official office, and almost every day there are unveiling posts sent in. At the beginning, the government still wanted to take care of it, but there was no way to investigate it for a while, and soon encountered the rise of the Ming army, and the various yamen had no strength to pay attention to it.

Ma Jiayi arranged it according to the interests and hobbies of the gentry in Hangzhou at that time, as well as their psychological characteristics, and made the post look like a tabloid with beautiful printing and pictures. The content of the unveiling post is also varied, some talk about ancient and modern China and foreign countries, some talk about astronomy and geography, some talk about getting rich and business economics, and more talk about clothing, food, housing, transportation, beauty and health care, which is quite eye-catching.

It is also mixed with Manchu sins such as Yangzhou Ten Ri and Jiading Three Massacres; Yongzheng Daxing Literary Prison, the legend of Lu Sanniang's flying sword to kill Yongzheng; What kind of big jade seduces Hong Chengchou, marries Dolgon and other Qing court palace barren yin stories. In particular, the description of the ambiguous things in the Qing court palace has many details that are vividly described, which makes people's blood rush when they read, and makes people love it.

Everyone on the balcony of the painting boat was chatting lively, and they saw a flat boat rowing from the direction of Qiantang Gate from a distance, and there were two scholars and a Taoist sitting in the bow of the boat, and everyone immediately changed the topic and talked about Fengyue.

The boat passed by the side of the painting boat, and the drinker surnamed Zhang saw clearly one of the scholars sitting on the bow of the boat, and he was surprised, "Hey, isn't that Dai Xu, the younger brother of Master Dai, who supervised the Zhejiang regiment?" How can he swim in the lake! ”

"This is Lord Dai's younger brother who doesn't seek a career and concentrates on arithmetic?!" Dai Xi was the former squire of the military department, and after returning to his hometown, he was ordered to supervise the regimental training in Zhejiang, so these officials on the balcony of the painting boat were all very familiar.

"It's him, this Brother Dai Ren has never liked to travel, he lives in a simple place to study arithmetic, and he can't ~~." At this time, the drinker surnamed Zhang saw another scholar turn his face, and suddenly realized, "It turns out that Xia Luanxiang, a master of arithmetic, is also on the boat, and that Taoist chief is probably also specializing in arithmetic, and they are probably having a party in arithmetic." ”

The Taoist priest dressed as Ma Jiayi, who first abducted Li Shanlan, who was translating in Shanghai, by printing textbooks such as mathematics, physics and chemistry of Jingmei, and then used Li Shanlan's letters to abduct Dai Xu and Xia Luanxiang on a cruise ship.

Li Shanlan was a mathematician, translator, and educator at that time, and his achievements in mathematics were mainly in three aspects: pyramid technique, stacking technique, and prime number theory. In less than 10 years, he translated nearly ten books. Euclidean Geometry (the last nine volumes), Algebra, Algebra, Calculus, and Conic Curves.

Dai Xu, the word Eshi, the number Heshu, also known as Zhongyi, was a native of Qiantang (now Hangzhou City, Zhejiang). Dai Xu mainly studied mathematics throughout his life, and his works include three volumes of Logarithmic Simplified Methods (1845), four volumes of External Cutting Density (1852), and two volumes of Circle Measurement of False Numbers (1852). There is also "Four Yuan Jade Jian Fine Grass" (1826), and the continuation of "Xiangshu Yiyuan" in seven volumes. There are also the last issues of "Pythagorean and Relatively Integrated" and "Diagram of Heavy Differences".

Xia Yingxiang is less intelligent and studious, works poems, jing painting things seal carving, and other books such as rhyme Bu Xian, can understand its mysteries. You Jing arithmetic, and Dai Xu are world friends. Xia Yingxiang's mathematical research is divided into two stages, the first stage is mainly the study of curves and square surgery, and the second stage is mainly the study of calculus, which enriches the content of the infinite series of Chinese arithmetic in the late Qing Dynasty.

Ma Jiayi sat leisurely on the boat, talking with Dai Xu and Xia Luanxiang about the application of arithmetic in the middle of the day.

"Arithmetic is actually a useful science, and all the knowledge of the Yi people comes out of arithmetic." Ma Jiayi pointed to the Leifeng Pagoda in the dark, "You said that the Leifeng Pagoda is here, how far is it?" ”

Dai Xu and Xia Luanxiang looked at the swarthy Leifeng Pagoda in the distance, and were a little embarrassed, "This can only be estimated casually." ”

Ma Jiayi straightened his right arm, clenched his right hand into a fist and gave a thumbs up, using the eye-skipping method to estimate, "About five miles." ”

Seeing that Dai Xia and the others looked suspicious, Ma Jiayi put down his arm and said with a smile, "The error will never exceed thirty zhang." ”

Xia Luanxiang hurriedly asked, "What kind of arcane is this?" ”

"It's just the simplest application of geometry, not some arcane." Ma Jiayi stretched out his right arm horizontally again, and explained it by gesture, Dai Xu and Xia Luanxiang were both arithmetic masters, and they were suddenly surprised.

The three of them were talking, and a woman's voice suddenly sounded in Ma Jiayi's arms, "Ayi, Ayi, Xiaoyu called." ”

Ma Jiayi took out the walkie-talkie, "Received!" ”

"The guest has left the Qiantang Gate, and everything is normal with us."

Ha, Han Yumo has taken Dai Xu and Xia Luanxiang's wife and children out of the city!

Ma Jiayi looked up, there were no boats near the boat, and the light around him was very dim, so he immediately instructed through the walkie-talkie, "Xiaobai Xiaobai, start moving." ”

At this time, it was about seven o'clock in the evening, at the peak of Wu Mountain, and a mortar had already been aimed at the city wall around Fengshan Gate in Hangcheng.

"You're a little white, your whole family is a little white." When Fu Baichen heard the message sent by Ma Jiayi, he spat viciously, then bent down to pick up a cannonball, gently put it into the barrel, and with a "bang", the cannonball flew towards the city wall.

With a loud "boom", the noisy Hangzhou City suddenly quieted down, and before people could react, another cannonball fell on the city wall.

After two loud bangs, Wang Youling, who was guarding the Fengshan Gate, hurriedly ordered, "This is an enemy attack, hurry up and shoot me!" ”

In the dark, the officers and soldiers defending the city did not know why, and hurriedly released guns and cannons, beat gongs and drums, and bluffed. Hangcheng suddenly fell into a panic, and the people shouted that the horses neighed into a pot of porridge.

Tonight, the governor's office sang in the back house, and the famous horns babbled and sang lively. As soon as the cannon sounded, Huang Zonghan immediately stopped the play. Someone came to report that the direction of Fengshanmen was shelled. Fengshan Gate is very close to the governor's yamen, less than half a mile away. I could hear the gunfire on the other side of the city wall, and the battle was very fierce, and the civil and military officers and their families were all frightened and panicked.

Looking at the messy appearance of the back house, Huang Zonghan immediately arranged for many dependents to go home separately, and at the same time summoned civil and military officials to gather in the detention room to understand the situation and discuss countermeasures.

Dai Xu and Xia Luanxiang were discussing arithmetic with Ma Jiayi, when a woman's voice suddenly sounded out of thin air, and the two of them were startled. Seeing Ma Jiayi take out an object from his arms and say some inexplicable words, Xia Luanxiang was more straightforward, and he immediately asked Ma Jiayi, what is this pretending to be a ghost for?

Ma Jiayi smiled slightly, "I'm the Ming Jinyi Guard, this is to send a message for the Ming army to open fire." ”

As soon as Ma Jiayi's words fell, a cannon sound sounded in the direction of Fengshan Gate, and Dai Xu and Xia Luanxiang couldn't help but be a little frightened.

"Don't panic, this boat is not safe, please get into the water immediately."

Dai Xu and Xia Luanxiang didn't have time to react, and "plop" and "plop" were taken to the lake by Ma Jiayi and Gong Gong.

As soon as the four of them fell into the water, there was a loud bang on the boat, flames flashed, and a flat boat was blown in two.

"That's Dai Xu and Xia Luanxiang's boat!"

Seeing that the boat had sunk to the bottom of the lake after being bombed, the drinkers on the terrace of the boat were so frightened that they crawled into the cabin, and they urged the captain to row the boat to the shore quickly.

The peak of Wu Mountain was still black, Fu Baichen was unhurried and sent a few more shells, looking at the chaos in Hangzhou, he proudly adjusted the mortar, and aimed the muzzle at the governor's yamen 1,500 meters away.

Dai Xu and Xia Luanxiang were pulled ashore from the lake like chickens in soup. In the outer building, the two changed their clothes, but they were still in shock.

At this time, the building outside the building was just a very inconspicuous lakeside shop on the edge of the West Lake, the owner Hong Ruitang was a Luodi literati who came to Hangzhou from Shaoxing to make a living, although he became a restaurant owner, his political heart has not been extinguished, so Jinyiwei recruited him.

Ma Jiayi told the two that the boat had been blown up, and the two were considered dead people in the Manchu Qing Dynasty. Li Shanlan has already served Daming, and hopes that the two of them can also serve Daming and use arithmetic for the country and the people.

Dai Xu didn't care, as long as there was a place for him to study arithmetic. According to Li Shanlan, he got a lot of arithmetic books from Ma Jiayi, and Dai Xu was looking forward to it. Xia Luanxiang was a little hesitant, the Xia family is a Hangcheng family, brothers and sisters are related to the official eunuchs, Xia Luanxiang's wife is still the daughter of Wang Yuansun, the cabinet secretary, he is reluctant to leave.

The sound of the carriage downstairs sounded, and Han Yumo accompanied Dai Xu, Xia Luanxiang's wife and children to get out of the carriage together.

Xia Luanxiang was taken aback when he saw Wang, "Why are you here?" ”

Tonight, the governor's back house set up a stage, and Dai Xu and Xia Luanxiang's wives and children should have followed Dai Xi's family members to listen to the play together. As soon as the convoy departed, the car in which Wang and Dai Xu's wife and children were riding together broke down, and they fell off after the transfer. Halfway through, the car they were riding in was stopped by Han Moyu again. Han Yumo showed Xia Luanxiang's jade pendant and said that Xia Luanxiang and Dai Xi accidentally fell into the lake and were rescued on the lonely mountain. The wives of the two were anxious for a while after hearing this, and they went out of Qiantang Gate in a daze.

Xia Luanxiang sighed, since he was already a dead person, and his wife and children were taken over again, he had to accept his fate.

It was eight o'clock in the evening, and Hangzhou had settled down from the chaos, and the sound of guns and gongs on the four walls of the city had also been calmed. Someone reported through the walkie-talkie that Ma Jiayi had left the governor's yamen, and other senior officials had left the governor's yamen and went to inspect the defense of the city wall, and Dai Xi and other officials had also returned to their homes, but Huang Zonghan was still in the Futai yamen.

Well, it's time to leave, and you're in control! Ma Jiayi immediately ordered to get into the car.

Ma Jiayi and Han Yumo accompanied Dai Xu and Xia Luanxiang to take three big cars with their families, preparing to bypass the lonely mountain and go straight to Gudang Town. There is a Wuxi fast moored over there, waiting for them.

As soon as the carriage departed, Ma Jiayi immediately told Fu Baichen through the walkie-talkie to prepare to evacuate.

Great! Fu Baichen put away the walkie-talkie and prepared to send the last two shells.

The last two were specially made incendiary bombs, and with a "bang", the shells flew out, drew a parabola in the air, and fell to the ground.

There was a loud "boom", and the direction of the governor's office suddenly burst into flames.

Another incendiary bomb, "boom", the flames suddenly rose into the air.

The news of the great victory in Hangzhou and the death of Huang Zonghan reached Běijing, the Qing court was shocked, and Cheng Fozhi of Zhenhai County was used as a scapegoat and was ordered to be immediately executed for the crime of losing land.
