Thanks to the melancholy de romance, the old way is inaction, and I would rather kneel and die three big rewards! Thank you very much!

Outside the south gate of Guilin City, Luo Qiongshu, who had a depressed face, pulled out his waist knife and fiercely split the already tattered charcoal city gate in front of him. Pen % fun % Pavilion www.biquge.info

He was very depressed indeed!

He strictly implemented the arrangement given by the Holy King, used artillery and climbing battles at the head of the city to attract the attention of the demons in the city, and quietly used the fire extinguishing water dragon designed by the Holy King on the Lu bus to spray sulfur water (concentrated sulfur * acid) hidden in the clay pot on the second floor of the Lu bus, and rot the wooden city gate, so that the city could be successfully broken.

Originally, everything was going well, and the Qing Demon soldiers at the head of the city were attracted by the brothers who bravely climbed the city wall. The two Lu buses quickly sprayed sulfur water on the hardwood gate, and as the gate turned black and turned into charcoal, the brothers in the Lu bus knocked it with an iron tool, and the charcoal fell; Then he sprayed sulfur water again, and continued to rot the wood inside, and in just over half an hour, the hardwood gate with a thickness of more than a foot was pierced.

Luo Qiongshu had already ordered his brothers to prepare early and began to charge towards the city gate. Unexpectedly, behind the city gate, the Qing Demon actually built another brick and stone retaining wall in the city, blocking the entire south gate.

This is Guilin City, which is the seat of Guangxi Province, not a small county town like Fuchuan and Gongcheng. Seeing that the great credit that was about to be made was blocked by the newly built wall, Luo Qiongshu was so angry that he almost vomited blood.

When he saw that there were still many gaps in the hated brick wall, through which he could see that the Qing soldiers were building the brick wall, he angrily ordered the soldiers to gather firewood, grass and damp branches, and set them on fire.

"If I can't get into the city, I'll turn you into smokey rats!" Luo Qiongshu hated itchy.

For a while, the south gate was full of smoke, and the Xiang Yong in the door and the Qing soldiers on the city tower were coughing because of the smoke.

..........

At the same time, Ding'anmen in the north of Guilin. Bai Huihuai led 2,000 Taiping holy soldiers to climb the ladder and fight hard in the city.

Due to the city wall of the northern section of Guilin, all backed by Diecai Mountain, built along the Li River and Mulong Lake, the siege area of the holy soldiers is narrow. Bai Huihuai also made a ruthless decision, and ordered the soldiers of the Holy Army to tear down more than ten roofs nearby, put all the wooden beams and wooden roofs in the water of Mulong Lake, and set up a ladder directly from the water to lean against the city wall, and forcibly attacked the city.

Outside the Dongzhen Gate in the east of Guilin, at the head of Zizhou Zhou, the main stream of the Li River, hundreds of Taiping holy soldiers mobilized more than 20 artillery pieces and fired artillery into Guilin City one after another, bombarding the Qing soldiers on the east city wall. The cannon crossed the city wall and blasted into the city, which happened to be the governor's yamen and the Eight Banners Guild Hall, causing a riot in the city.

However, these were not the focus of the Taiping Sacred Army's offensive.

Under an unnamed mountain ridge on the northwest side of Guilin City, Feng Yunshan confidently looked at the city wall next to Baoxian Bridge three hundred steps away, with a hint of a smile on the corner of his mouth. This section of the wall was the target of his main attack. There was no signal from the south side of the city, and it seemed that the plan to attack the city through the city gate had failed. However, he was not surprised, this was the provincial capital of Guangxi, and if it was easy to attack, it would surprise him. Therefore, he gave the order to destroy the walls in advance!

Originally, if the concentrated sulfur * acid in the giant Lu bus on the south side of the city gate could successfully corrode the city gate, and the soldiers of the Holy Army could rush into the city from that side, he would have ordered the nearly ten thousand soldiers of the Holy Army who were ambushed here to be transferred, and they would attack the city from the south gate, so that they would not have to waste a lot of trouble destroying the city wall and then attacking the city.

It turned out that he had already sent someone to investigate, Guilin city walls are all built along the water's edge, but some are brick walls, some are blue bricks and stone staggered mixed masonry, only the northwest corner of the city wall, all of which are built of stone, is the most solid. However, for Feng Yunshan, this is exactly the best offensive part he is looking for, the strongest stone, and it is precisely the obstacle that he thinks is the softest!

Because, in the hundreds of cans of "Feng's Potion" he brought with the army, in addition to concentrated sulfur * acid, there are also salt * acid made from sulfur * acid and table salt.

That's right! After studying chemical engineering, he produced concentrated sulfur * acid at the sulfur * acid factory in Guiyang, and he has been accumulating the produced sulfur * acid as a secret weapon.

After deciding to attack Liangguang, he remembered an incident about the city wall of Guilin. When he first worked before crossing, he once traveled to Guilin once, and heard the tour guide at that time say that the ancient city wall of Guilin was all built with stones, but unfortunately, later, the city walls were all demolished, and all the stones were built into embankments on both sides of the Li River. At that time, he was still thinking about digging up stones, maybe it was an antique thing, so he was very impressed.

Feng Yunshan knows that the strip stone is limestone, the chemical composition is calcium carbonate, and slightly stronger acids will react with calcium carbonate to produce carbon dioxide and water. And the concentrated sulfur * acid just can't react with a large amount of limestone, all Feng Yunshan thought of salt * acid, as long as there is enough salt * acid, no matter how big the stone can react and melt away, in this way, can't you directly break the city?

However, Feng Yunshan, who has been an engineer for many years, is accustomed to being rigorous, and he still made a simple calculation, considering the specific gravity of the stone and the concentration of hydrochloric acid, and concluded that it takes 20 times the same volume of 25% hydrochloric acid to dissolve and react a piece of stone.

It's a pity that because there is not much salt, he has to prepare more than 600 jars of salt*acid, if you want to turn the stones of the entire city wall, this amount is estimated to be not enough for even three or four meters of city wall. However, he thought that by melting a few stones at the base of the wall, the wall would collapse, and if he added some explosives, he would not have to worry about it.

Under the city wall next to the Baoxian Bridge, hundreds of holy soldiers and four small Lu buses had already approached the city wall.

The holy soldiers pretended to set up a ladder and branded a knife, causing the Qing soldiers to stick out their heads, and the shotgunners squatting on the opposite side of the river bank shot a row of projectiles, so frightened that the Qing soldiers at the head of the city hid behind the battlements and fired indiscriminately under the city wall, and from time to time a few stones without accurate heads rolled down from the city head, but injured several holy soldiers. Obviously, this remote city wall was not commanded by an effective Qing general.

The fierce siege of the holy soldiers at the south gate and the north gate attracted a large number of regiments in the city to train the villagers. On this section of the strongest stone city wall, naturally not many villagers were arranged to come. The Qing troops stationed in the city were not large, and because the nearby north gate was tight, more than 100 Qing troops were transferred to support, and the number of Qing troops in this section of the city was even less. Fortunately, the holy soldiers did not attack the city very quickly, but they could also support it.

Seeing that the eight water dragon copper pipes under the four Lu buses had stretched out to align with the foundation stones of the lower part of the city wall, Feng Yunshan couldn't help but take a few steps forward, wanting to see more clearly. This is the siege method he came up with, and no one has used it since ancient times, so he can't help but look forward to it.

"Holy King, you can't get too close to the city wall, in case it is discovered by the Qing Demon at the head of the city, and a cannon comes down, Shengbang can't explain to the Holy Army brothers." Liu Shengbang came out to stop him.

Feng Yunshan smiled at Liu Changyou, who was following him, and said, "If you become a holy king, sometimes you can't be the master!" ”

Liu Changyou didn't laugh, he kept looking at the water dragon copper pipe under the city wall. Although he didn't say it on his face, although he also believed that the Holy King would not lie to him, he was still very skeptical, that potion was really powerful enough to melt all the hard stones?

He thought about it, but still shook his head, just wanted to persuade the Holy King to stop playing this kind of careful thinking, or to mobilize the Holy Army soldiers, and forcibly attack the city without stopping, looking for the weak parts of the Qing soldiers to see if they could attack the city. Unexpectedly, when he raised his head and looked at him on the strong city wall, his mouth couldn't close, and his eyes almost fell off!

The lower part of the city wall, which was originally a place full of solid stones, actually appeared several holes! As the potions in the eight water dragon brass pipes continued to flow out, the holes grew bigger and bigger. The hard stone slowly melted away like ice and snow seeing sunlight. Is this still a stone?

Liu Changyou turned his head to look at Feng Yunshan beside him, and saw that his face was not surprised at all, as if he had known that this would be the case! It's just that there is a faint excitement and expectation on his face, it seems that the Holy King's erudition is far from being comparable to himself.

Just when Liu Changyou was thinking wildly, those holes finally couldn't support the weight of the entire city wall, boom, a section of the city wall more than 20 zhang long collapsed, and the fallen stones rolled down into the water next to it, making a huge sound.

Before they could evacuate, two of the Lu buses were smashed by the collapsed city wall, and several of the holy soldiers inside were knocked into the water by the collapsed stones before they could jump into the river.

"Kill!" Next to the collapsed city wall, hundreds of impatient holy soldiers who had been waiting for a long time jumped through the collapsed gap and rushed into the city, fighting with the Qing soldiers who heard the sound and hurried over to block the gap.

Feng Yunshan waved his hand, and the herald next to him immediately waved the flag, and the rapid war drums sounded, and nearly 10,000 holy soldiers in the mountains rushed to the gap to kill.

……………….

Lao Chongguang, who was carried by Xiang Yong, rushed to the north city gate, just got off the sedan chair, suddenly heard a huge rumbling sound in the northwest direction of the city, and was about to send someone to see what was happening, and suddenly heard a rush of killing shouts from the northwest direction more than a mile away, and then, thousands of regiments of Lian Xiang Yong cried and shouted from the northwest side, and the two guards around him grabbed a Xiang Yong and asked: "What happened?" ”

"Your Excellency, the Hairy Thieves have blasted through the walls and entered the city! Run for your life. ”

Hearing this, Lao Chongguang's blood rushed to the top of his head, and he suddenly felt that the sky was spinning and he fell to the ground!

"Guilin City is broken! Guangxi is finished! ”
