Yuan Yun is now thinking of the Japanese kamikaze, the Mongols invaded Japan in a big way, but they were overturned by a gust of kamikaze at sea, and almost all of them were buried in the sea.

And now, looking at the pouring rain outside the camp tent, Yuan Yun smiled bitterly at the corner of his mouth, when the cannon was erected, before he could angrily spit out flames, the sky began to rain drops, and then gradually became larger, and finally the gunpowder army had to cover the cannon with a tarpaulin again.

The heavy rain has been falling for two days in a row, if it continues to delay, I am afraid that the 70,000 army led by Yuan Shang will return, and in this weather, Yuan Yun's remaining magic weapon is only a sharp weapon like gasoline.

Taking a hard bite of the fritters in his hand, Yuan Yun instructed Shi Shen, who was guarding the side, to ask him to call all the generals in the camp, he needed to be decisive at present, and if he hesitated, he didn't know how long it would take.

Shi Shen walked before leaving, Xu Shu got into the camp tent covered with rain, shook off some of the water on his body with his sleeves slightly, and then found a folding stool to come out, did not sit down in a hurry, but smoothed the water droplets on the stool with his cuffs, and then sat up, and then did not speak, and picked up the fritters on the table and ate them.

Yuan Yun watched patiently from the side, and estimated that he had already thought of it in his heart, Xu Shu came over this time to ask himself about the method of attacking the city, and it was estimated that he had some careful thoughts, that is, after knowing that gunpowder could not be used in rainy days, he needed more detailed information to make more preparations for Liu Bei.

Xu Shu finally finished eating, and directly wiped his mouth with his sleeve, and then grabbed the teapot and poured it violently, Yuan Yun frowned when he looked at it, because Xu Shu's sleeves were too functional, blocking the rain, wiping the stool, and now he can wipe his mouth, how can he stay away from his two wide sleeves in the future.

"Now that the rain has no chance of stopping, since the cannon can't be used, isn't Yuan Hou ready to do something else?" Xu Shu finally began to ask.

Yuan Yun felt that it was necessary to correct the other party, lest this thing think that he could be complacent if he found the weakness of gunpowder, so he said with a smile: "The cannon is not unusable, even if the heavy rain falls, it can still be used, the only trouble is the follow-up maintenance, which is quite a cumbersome process, so Ben Hou ordered the cannon to be put away, after all, our main target is Yecheng in the back." ”

Xu Shu was stunned for a moment, and said in disbelief: "Since Yuan Hou said so, it is naturally the truth, but now that the artillery is useless, how can this Liyang be attacked?" ”

Yuan Yun sighed lightly and said, "Doesn't Brother Yuan have the consciousness of being a staff member? I have to ask Ben Hou every time, and now Ben Hou feels that the dividends given to Xinye Yicheng are too much, because Brother Yuan has been watching and has not given any good advice, do you say that this transaction Ben Hou is a loss? ”

Xu Shu was stunned again, and then laughed out loud in an instant, and said: "Yuan Hou is really different from other nobles, not only is Yi Ya's ability great, but he is also very specialized in doing business, and he is better than ordinary businessmen......

Yuan Yun frowned impatiently, and without waiting for Xu Shu to finish speaking, he directly grabbed it: "Why, look down on businessmen, then you Xinye don't go to do any business, everyone is holding the title of a nobleman and waiting to die there." ”

Xu Shu hurriedly bowed his hand and said: "Yuan Hou misunderstood, what I Xu Yuanzhi admires most is a refreshing person like Yuan Hou, who can do whatever he likes, where do you care if other people will be chattering, how about businessmen?" How about craftsmen? Didn't Yuan Hou use these people to achieve a great cause, so I just envy Yuan Hou. ”

Very good, this sycophant is very exquisite, Lao Tzu is very cool.

Yuan Yun was a little proud, and then turned the topic back to attacking Liyang City, and said: "In addition to the cannon, Ben Hou also has a sharp weapon in his hand, and there is nothing to hide about these things, if the heavy rain does not stop tomorrow, Brother Yuan Zhi can see it." ”

After speaking, Yuan Yun's brows furrowed again, shook his head and sighed and continued: "Just like that, we will have to get close to the attack, and the defenders at the head of Liyang City will definitely fight back, and it is estimated that the brothers of the Gunpowder Army will suffer a lot of casualties, which is definitely not what Ben Hou thinks, alas." ”

Xu Shu thought for a moment, but didn't ask about this new weapon, but said with some concern: "Now that there are at least more than 20,000 defenders in Liyang City, does Yuan Hou plan to fill it with human heads?" If this is the case, our side will inevitably suffer heavy losses, and even if Yuan Shang's 70,000 army does not return, we will not be able to continue to attack Yecheng. ”

Yuan Yun shook his head and said: "You don't need to climb the wall to attack the city, you only need to press five hundred steps in front of the city wall, so that our trebuchet can throw gasoline cans into the city, as long as the fire burns, Liyang will instantly become a fire city, but if you do this, it is equivalent to entering the range of the enemy's trebuchet, so there will inevitably be a large number of casualties." ”

Xu Shu heard it inexplicably, after all, he had never seen gasoline, but he still understood the burning of the fire, but now that the rain was pouring down, it was a joke to attack with fire, so he didn't know what Yuan Yun said?

Glancing at Xu Shu's demented appearance, Yuan Yun smiled, and took out a jar from the iron stove beside him, which was naturally filled with gasoline, and this gasoline stove was currently only used by Yuan Yun, because he always liked to open a small stove for himself.

Pouring a little gasoline from the jar into the clay basin, Yuan Yun casually dragged the oil lamp on the side, and then easily ignited it, which made Xu Shu startled.

Yuan Yun saw that Xu Shu's face was full of surprise, and handed over the bowl where he was drinking, and then said with a smile: "Brother Yuan Zhi wants to put out the fire?" ”

Xu Shu took the water bowl with a puzzled face, and poured it into the burning clay pot in an instant, and suddenly the flame immediately rose two feet high, not only was it not extinguished, but it became more vigorous.

Holding the water bowl for a long time, Xu Shu suddenly laughed and said: "Yuan Hou is really a child of immortals, and there are really a lot of magic weapons in his hand, this kind of water-doused flame is used to attack the city on a rainy day, it is really good, but Yuan Hou is too casual, if he just uses a trebuchet to throw these gasoline into the city, the casualties of the gunpowder army will immediately expand several times." ”

Yuan Yun instantly stood up from his position and asked eagerly, "What do you say about Brother Yuan?" ”

Xu Shu stroked his beard and smiled, and then replied lightly: "The defenders in Liyang City are not stone people, when these unquenchable flames are burning in the city, the guards will only make two reactions, one is to retreat from the north gate to preserve their strength."

The other is to lead the army out of the city to fight a decisive battle, at least there is still a chance for this, and I think the latter is more likely, after all, Yuan Shang is not as generous as his father Yuan Shao, and there is almost zero tolerance for defeated generals.

If you abandon the city and flee like this, the end will definitely not be very good, so the defenders will inevitably go out of the city to meet the battle, at least destroy all your trebuchets, otherwise there will be no way to explain at all. ”

Yuan Yun sighed secretly in his heart, he originally thought that the foolproof tactics were so vulnerable in front of Xu Shu, if the defenders in Liyang rushed out, he could only meet in a hurry, although there were steel crossbows and other sharp weapons, but the other party poured out of the city, and he did not have the corresponding preparations, and the casualties would definitely expand.

Suppressing the panic in his heart a little, Yuan Yun secretly praised Xu Shu's shrewdness and thoughtfulness, and it is estimated that he still needs to learn a lot, at least in the battle array, he still has to be more careful in the future.

After thinking about it, Yuan Yun bowed his hand and said: "This time, I used a component of South Vietnam to exchange for Brother Yuan's strong help, it seems that Ben Hou is not at a loss, thanks to Brother Yuan's reminder, so that Ben Hou has avoided a big casualty." ”

Xu Shu smiled bitterly and said: "Although Yuan Hou can be reminded, but the city always has to be attacked, if the defenders in the city really go out of the city for a decisive battle, I, Xu Yuanzhi, have no specific countermeasures, so I am very ashamed to help Yuan Hou." ”

Yuan Yun shrugged his shoulders disapprerovingly, and then pointed to the outside of the camp tent and said: "Brother Yuanzhi, it's better to go with me to see something, Ben Hou didn't plan to use it before, and now that he is worried that the defenders will rush out, he naturally needs to let the other party see the power of science." ”

"Science?" Xu Shu was confused when he heard this.

……

Squeak! Rumble!

The two voices were repeated in a coherent manner, and the Gunpowder Army had brought the trebuchet closer to the wall five hundred paces, and then the two sides began such a stalemate battle, you throw a boulder out, and I will send back a can of gasoline.

However, as time went on, the trebuchets on the walls fired fewer and fewer boulders, because almost the entire wall was burning with fire, and the defenders kept fleeing in all directions, and the trebuchets on the walls were too heavy to move, so they could only watch as they slowly burned in the flames.

At the same time, Cao Ang and Zhang Jaw also concocted the same method at the east and west gates, constantly throwing a large number of gasoline cans into the city, and the entire city of Liyang City began to burn into the sky.

Yuan Yun looked at it almost, so he ordered the lieutenant generals to start pushing out the three sprinkler trucks, and the three behemoths were like giant elephants, slowly moving towards the city gate.

Since the old oxen pulling the cart were all set up in the interior of the sprinkler truck, they did not appear too panicked under the protection of thick steel plates, and the soldiers who drove the cart could only hear the continuous popping sound of arrows shooting outside, so they did not care at all.

Xu Shu rode to Yuan Yun's side, and then looked at the battlefield in front of him, there was no such traditional scene, there were no soldiers pouring out like a tide, and there were no arrow feathers flying down from the wall like raindrops, only the fire burning on the city wall, even if there was a heavy rain falling in the air, it still could not stop the spread of the fire.

"The walls of Liyang have been lost, and it is estimated that it will not be long before the enemy will pour out from the city gates."

After Xu Shu finished speaking, he couldn't bear to glance at the city gate in the distance, and in the morning he saw Yuan Yun demonstrate the power of the sprinkler truck, so he now knew very well what kind of terrifying scene he would face once the soldiers in the city rushed out.

At this time, a herald arrived, and then immediately knelt down on one knee and said: "General Qiyu, the sprinkler is already in place, just wait for the other party to lower the hanging door." ”

Yuan Yun nodded, and then ordered: "Take a hundred steps forward with the trebuchet and start throwing gasoline canisters behind the city wall, so that the enemy cannot reach the top of the wall." ”

Not long after the herald went down, he saw that the hanging door of the southern city suddenly shook, and with a creak, the gate began to fall slowly.

At this time, the three sprinkler trucks all stretched out their sprinkler heads, and instead of spewing fire, they began to spray gasoline continuously on the long bridge in front of the hanging door, and soon the place was filled with a pungent smell.

Finally, the defenders in the city lined up in a square line, holding shields, and began to pour out of the city gate, and the city tower was still releasing arrow feathers, but when they shot at the sprinkler truck, they could only be shallow for half a minute, causing the three sprinkler trucks to quickly become hedgehogs.

The Powder Army warriors hidden behind the sprinkler had begun to build the first line of defense, the combined steel shields were firmly embedded in the dirt, and then rows of special crossbows were erected.

The slaughter begins!
