Back to Ming Dynasty with Industrial Revolution System

Chapter 141 Digging Tunnels

Dai Shan and others waited in the city for a day, but Li Sizhong's envoys did not come back.

"Chu Yun is so ruthless that he even detained the envoy without any news." Dai Shan had nothing to do with the Fu Liao Army who did not play cards according to common sense.

"They have probably been killed." The officials in the Later Jin court couldn't help thinking this way, and they were glad that they were not envoys.

"Everyone, the Liao army is coming in menacingly. It is impossible to seek peace through grievances. We can only fight to the end." Dai Shan dismissed the idea of ​​peace talks with the Liao army.

Every time a team of envoys was sent, they were detained by Chu Yun, even if there were not enough people.

"Has Azig from Zhengbaiqi arrived yet?" Daishan asked an official.

"Azigbeile sent a letter saying that the slaves rioted in Jianzhou. He is busy returning to the army to suppress the rebellion. He will send troops over after dealing with the rebellion," the official said.

"That group of despicable slaves in Jianzhou dared to betray our Dajin. Well, let Azig's Zhengbai Banner kill them all before coming back. The strength of our four banners is enough for them." Dai Shan frowned. head.

"Dabeile, Amin and Yuetuo let you go, saying that the enemy army in the city has made new moves." The young Dorgon said to Daishan.

"Let's go." Daishan's mood was extremely depressed.

Amin and Daishan, who were in charge of the defense, discovered that after the bombardment of the Liao army today, there were many gullies under the city overnight, approaching Shengjing City in a zigzag shape, and not only one, but three, from different The direction is like three iron cables stretching out, trying to trap Shengjing, the yellow dragon.

"The Fu Liao Army intends to attack our Shengjing City by hiding from the ground?" Dai Shan brought a group of officers with red flags to the top of the city. When he saw the Koryo soldiers under construction in full swing, he could see Chu Yun's intention at a glance.

"Their artillery fire can't destroy the solid city wall, so they have no choice but to use this bad strategy." Amin said, "This time we learned from the experience and lessons of the Battle of Haizhou. We deployed a small number of defenders on the city wall, and then reinforced the fort. So the casualties were not heavy."

"Not bad, it seems that the artillery fire of the Liao army is not invincible. As long as you deal with it carefully, you still have a chance to win." Dai Shan nodded affirmatively.

"The Fu Liao army approached the city wall with tunnels, and I don't know which tunnel is the real place for them to attack the city." Yue Tuo stared at the three tunnels that kept emitting dust from the outside.

One of the tunnels leads to the direction of the city gate, and the other two tunnels lead to the city wall.

"No matter which tunnel they want to use to capture our Shengjing City, we can use artillery and falling rocks to destroy their tunnel when the tunnel is close. In addition, we have placed large urns in various corners of the city to monitor the underground movement." Amin said.

"Amin's words are right. Soldiers come to block the water and cover them with soil. We will stop the battle quietly. This battle will surely win." Dai Shan dismissed Chu Yun's obviously moving siege strategy.

The earth attack pursued surprise, but Chu Yun, who pursued speed, made great efforts to build, and used about [-] crude tunnels that were half completed overnight, and then slowed down after approaching the attacking range of the defenders.In this way, Chu Yun's strange plan became a public plan, without surprise.

Just when the bannermen of the Eight Banners dismissed their schemes, a chemist from the British Empire welcomed into Chu Yun's army.

"Wolf, you are here, and I have been waiting for a long time." Chu Yun saw the chemist, not only did he not blame him in his tone, but rather excited.

Wolfe is a new scientist at the Liao Military Academy of Sciences, the leader of the Department of Chemistry. For this operation, Chu Yun also sent dozens of smart students from southern Liaoning to lead the project with Wolff.As for how Wolfe got here, of course Chu Yun used the industrial revolution system.Picric acid - a technology in the late 18th century, it doesn't cost Chu Yun many civilization points, but it's worth it!
Picric acid, a yellow crystal, was originally used as a yellow dye and was invented by Wolfe in the late 18th century.However, its true value was not discovered by the world until 100 years later. This is a strong explosive, which is ten times and a hundred times more violent than the black powder commonly used before!It is precisely because it was originally used as a yellow dye that later people often called it yellow dynamite to distinguish it from the previous black dynamite.

Originally, the most famous explosive that Chu Yun remembered was TNT, and Nobel, the famous father of modern explosives, but the points of civilization consumed by nitroglycerin, TNT and other technologies in the 19th century were unimaginable, so Chu Yun could only use them in the 18th century. Find a way in the technology.Regarding the modern explosive technology after black powder, the ambulance in the 18th century is better than nothing, but it still made Chu Yun discover picric acid, a chemical that appeared in advance but was not discovered by people at that time, and was used as a dye!
This time, Chu Yun sent people to assist Wolff in order to produce picric acid on a large scale.Even if there is no way to apply new types of explosives to muskets and cannons, it is still possible to directly pull a large amount of picric acid into the tunnel to detonate.

"Sir, there are too many products, and we had a hard time rushing to get them out. According to my calculations, the thickness of the city wall and the foundation are only enough for one use. Sir, you must use it carefully." Wolfe kindly reminded Chu Yun.

This time, what he and his students brought was his masterpiece, the high explosives sealed in wooden barrels and some detonating explosives in two carriages.The words "Strictly No Smoking and Fire" are painted on it with red paint.

"That's great, but then you may have to guide our soldiers to detonate these chemicals. After all, our soldiers can't master the power of these explosives." Chu Yun said to Wolfe.

"I thought I made a new type of dye, but I didn't expect it to be an explosive... This is the first time I have used such a large-scale picric acid explosive. I'm not afraid of ten thousand or just in case... I'm not very sure ..." Wolf was a little nervous, "We used a batch of picric acid explosives to blast the mine in Gaizhou City, but in order to save materials, we only used two hundred catties. The power is very powerful, and it will cause a fire... ...So please, don't be detonated by enemy artillery or firearms, otherwise..."

"I'll be careful." Chu Yun's eyes lit up when he saw these two cars of new explosives that were far more powerful than black powder, but he was also very worried.Such a violent load of explosives is in the barracks, if it is accidentally detonated, it is estimated that both myself and my barracks will go to heaven.

"Yu Cheng, you lead the guards to strictly guard this batch of gunpowder, and don't let anyone get close. In addition, let Dong Dawei's artillery battalion prepare several thousand catties of black powder, and let's have a big game." Chu Yun said to Yu Cheng.

"Okay...Okay..." Yu Cheng swallowed with cold sweat, he was a little square, this is two cars of explosives that can blow up half an army camp.
