The glass shield was naturally purchased by Su Baiyi from the department.

Some of the explosion-proof glass in the system is specially used for the armed police in later generations, and this thing can be used to prevent ordinary bullet shooting, so the bow and arrow are naturally not a problem.

At the beginning, Su Baiyi originally wanted to buy some anti-riot helmets, but then he gave up after thinking about it. Helmets are not as simple as shields, they not only have glass on them, but also a variety of industrial products, such as rubber, plastic, and so on.

When these things were seen by the soldiers and students, they inevitably became suspicious and could not be drawn. Besides, now that there is an explosion-proof glass shield, it doesn't really make much sense to have this helmet or not.

Ever since Su Baiyi equipped the soldiers at the head of Shangqiu City with explosion-proof glass shields, Luo Rucai's nightmare under the city began. First of all, he concocted the same method according to the original Song Zuzhi, and each city gate sent 2,000 archers to suppress the formation, and the rest of the many people attacked the city together.

But he found that the archers he shouted over to press the formation instantly lost their effect, and the soldiers at the head of Shangqiu City were wearing transparent shields one by one, no matter how many arrows you flew up, all of them were blocked for you, without exception. With the defenders in good sight, the siege soldiers climbing the ladder below were completely useless.

Because of the good sight, once there were soldiers attacking the city, the defenders of the city would shoot arrows desperately, and after a few times, Luo Rucai lost thousands of men and horses, and the defenders at the head of the city not only did not die, but even very few were injured.

The key is that the people guarding the city are still relaxed and happy, which makes Luo Rucai quite crazy.

"What should I do?" Luo Rucai looked at the head of Shangqiu City with hatred, and looked at the subordinates around him with some dejection: "What did this Su Baiyi do?" Isn't the glass brittle, it shatters at the touch of a button, why is the shield made of glass in their hands so hard that it can block the attack of bows and arrows? ”

No one can answer this question.

Luo Rucai looked at Song Zuzhi, Song Zuzhi had no choice but to come out and arch his hand: "Dashuai, now that Su Baiyi has taken precautions, it seems that it is really difficult to attack the city with a cloud ladder like us." ”

"Nonsense!" Luo Rucai gave him a blank look.

Lu Xiong next to him couldn't stand it, and looked at Song Zuzhi and said: "The military advisor's words are scolding, what does it mean to be headless and brainless, isn't this method of using archers to suppress the formation and attack the city also do you think of?" If you want to say that you have no brains, you also have no brains! ”

"You ......" Song Zuzhi was scolded twice by Lu Xiong, his fingers trembled, and he said tremblingly: "You insult Sven." ”

"Alright, alright!" Luo Rucai interrupted the two with a wave of his hand: "To be honest, the method that Song Junshi thought of is actually not bad, you have all seen it, this method of pressing the formation was quite effective at the beginning, and our brothers even climbed to the top of the city." It's only to blame that Su Baiyi is too treacherous, and he actually made things like glass shields. Alas...... Could it be that I, Luo Rucai, are unlucky? ”

Lu Xiong lowered his head with a dark face.

Song Zuzhi arched his hand and said: "Don't be discouraged, as the saying goes, one foot tall is one foot high, since he Su Baiyi has cracked our siege method, let's go sideways." ”

"Oh?" Luo Rucai's body shook, and he suddenly came to his senses, and his two eyes stared at Song Zuzhi roundly: "Why did Mr. teach me?" ”

Song Zuzhi said: "Did you forget the handsome? When we were in the first wave of tentative attacks, we used rafters to attack their city gate, and in my observation, this city gate is the death hole of Shangqiu City, we only need to smash its death hole and break its city gate, which is naturally also a method. ”

"That's right!" Luo Rucai clapped his hands and said, "Why don't you say that you are the commander of the army...... Hahaha, hahaha, Song Junshi, he is handsome in the south and is lonely, you are Zhuge Liang and Liu Bowen of this handsome. ”

"The grace of the handsome encounter, Song is willing to serve the dogs and horses!"

"Good, good, good!" Luo Rucai said to Lu Xiong: "Just do what the Song military master said, select five hundred strong, wearing heavy armor, and take rafters to attack the city gate." Hehe, you have a good plan, I have a wall ladder, what about the glass shield? Lao Tzu doesn't play siege with you, Lao Tzu will smash your dead hole, smash you, smash you! ”

Lu Xiong commanded! Then with the heavily armored soldiers, he dragged the siege wood made of thick tree trunks and ran towards the west gate at a high speed. Because the soldiers were wearing heavy armor, the arrows at the head of the city could not hurt anyone even if they were fired. These soldiers came to the city gate with the siege wood very smoothly, and one by one they gathered enough strength and crashed towards the city gate with all their might.

"Bang, bang, bang" came with a sturdy crunch, which made the soldiers' arms tingle.

Lu Xiong looked at the city gate and said, "No, this voice is not right, it seems that something is blocked behind the city gate?" As he spoke, he went into the gate, and looked through the crack in it, but he could not see what was inside.

"No matter, hit it first, and wait until the city gate is slammed open."

A group of soldiers used their strength to feed, took turns to change five groups of people, and bumped into the city gate for a full afternoon. Finally, the hard work paid off, and the city gate was slammed open.

Not only was the deadbolt broken, but the rotating hinge behind the door frame was also broken.

A huge door slammed into the ground outside the city in reverse, and then ......

Lu Xiong was dumbfounded.

"What is this?" Facing a huge whole concrete wall, all Lu Xiong could do was to slash a few times with a knife on it, and suddenly jumped up: "Dog, this is a stone egg, Su Baiyi was so mad that he actually set up a large stone tablet behind the gate, I said how wrong this voice is." ”

"Come on, hit me with a rock!"

The group lifted the log and began to ram it against the concrete wall.

The concrete has been ready for more than two days, and although the strength has not reached the highest, it has reached more than 80% of the standard strength, which is 50 centimeters thick and 3 feet into the ground.

That's not all, in order to keep the wall strong, Su Baiyi asked people to pour three vertical gravity diagonal braces behind the concrete wall.

Lu Xiong led people to bump into each other for half an hour, but the wall still didn't move.

came back to report to Luo Rucai, Luo Rucai looked at it with a clairlight for a long time, sighed and said: "This son of a bitch's Su Baiyi, such a big stone, how did he get it, the nearest thing in Shangqiu City is Mangdang Mountain, but even if it is to take such a big stone from Mangdang Mountain, it will take at least half a year." Could it be that he had an unpredictable prophet, and he knew that Ben Shuai was going to attack the city? ”

Speaking of this, he suddenly thought of something, and patted his head fiercely: "How did Ben Shuai forget, this Su Baiyi is known as Xiao Zhuge in the world, it is said that he has known for 500 years and a thousand years later, and Ben Shuai is careless." ”

Song Zuzhi said disdainfully: "The big marshal's words are fallacious, Su Baiyi is just a little more clever than ordinary people, if you say that you know five hundred years and a thousand years later, it is a deceptive word." ”

"Alas!" Luo Rucai sighed and asked: "Ben Shuai's life and this surnamed Su live and restrain each other, the method that the military advisor came up with is not a miracle to use elsewhere, it can be used in this Guide Mansion, it is really Ke's death." You say this glass shield, this stone wall, alas......"

"Don't panic, your subordinates still have a way!" Song Zuzhi did not give up, and squinted at the head of Guide Mansion.

"Is there a way?" Luo Rucai said: "Then the military advisor quickly teach me!" ”

"My subordinates remember that when we pulled out the camp from Xingyang, the general soldiers of Yuanda in Luoyang seemed to have sent us two carts of gifts!" Song Zuzhi looked at Luo Rucai.

Luo Rucai smiled bitterly: "Yes, Yuan Mo of the dog day sent two trucks of gunpowder, but we don't have a red-coated cannon in our hands, and we don't have firearms like firearms...... Amount, amount...... Ben Shuai seems to understand that the military division is using gunpowder to blow up the city. ”

"There is too little gunpowder, it is not enough to blow up the city!" Song Zuzhi took a deep breath and said: "Although it is not enough to blow up the city, the marshal can put it in the weakest place of the city, and then detonate it with a rocket, at least it can blow up a hole in the city wall, and then we will take the opportunity to kill into the city, and this matter will be done." Even if we can't get in, there is a gap in this city, and they will definitely not be able to fill it in a hurry, which is also a great benefit to us, isn't it? ”

"yes, that's a good idea!" Luo Rucai slapped the table: "That's it!" ”

I have to say that Song Zuzhi's method is excellent.

It's really good.

After dinner, Luo Rucai arranged dozens of soldiers in heavy armor to secretly put two truckloads of thousands of catties of gunpowder on the left side of the north gate, and then shot rockets from a distance, which immediately detonated, catching Su Baiyi off guard.

The explosion of thousands of pounds of explosives can be imagined.

Under this explosion, not only did the small half of the north gate be blown away, but the city wall on the left side of the north gate also blew up a huge gap, and more than a dozen soldiers defending the city died.

But after all, this is just a gap, not the loss of the entire wall.

The soldiers defending the city can be said to be incompatible, and the thief army outside is pouring over like a tide, but only a few people can pass through the gap each time, so that the two sides have fought around the gap all night without any result.

When the day came, the personnel of the two sides had withdrawn, and the gap had been unconsciously repaired by the students of the Yuyuan Academy.

Furthermore, after repairing, it is more solid. Because they're using concrete!

It was only at this moment that Luo Ru knew where the huge stone walls of the four gates of Shangqiu City came from.

"What is this thing that can turn mud into stone?" Luo Rucai's eyes were bloodshot, and he gritted his teeth angrily: "More than 2,000 people died, but I saw that people filled the gap, and now the wall has turned into stone." This Su Baiyi, damn it, what kind of monster is he, is Lao Tzu and him born to commit crimes? ”

"Dashuai!" Song Zuzhi arched his hand and said: "Don't be careful, this Su Baiyi has some tricks, and we are not ......."

"Say no more!" Luo Rucai showed a crying expression on his face: "Let's go, let's stop fighting, let's withdraw our troops, we can't play him!" Su Baiyi, this bastard is a crab, and he can't gnaw it! ”
