In August of the 4th year of Emperor Guanghe of the Han Dynasty, Guanzicheng had been besieged for a month, and Gongsun Zhan relied on his perverted command ability to build Guanzicheng into a solid foundation. Even the gates, which had no gates, have now become a nightmare for the enemy!

At first, the enemy really wanted to attack through the city gate, but several times it was either attacked by Gongsun Chan with fire or buried in a pit, or it was poisonous smoke and stray arrows, anyway, every time a troop wanted to move away from the pile of things, it basically left a corpse in one place, and in the end it ended in vain.

This is naturally indispensable to the credit of the players, Gongsun Chan knows that the Inhumans value profit and life, and under the high bounty, they can kill hostile forces, and they have developed suicide attacks on various players who defend the city gates. For example, if you take poison ivy herbs and light them yourself, the enemy will be stunned by the poisonous smoke before you can lift those heavy objects, and then let others slaughter them! Of course, the survival rate of this kind of suicide attack is extremely low, but these are not taken seriously by players!

For more than a month, more and more players from the imperial court camp came to the aid of Gongsun Zhan. Some of these harass the enemy on the periphery of Guanzi City, and some are trying to find a way to enter the city to directly support, and the more humane system is the group of players who originally followed Gongsun Zhan, even if they die in battle, they are resurrected in Guanzi City, which can be said to be bound here, which is a great help for Gongsun Chan to command the battle.

The walls of Guanzi City also changed hands several times in a month, but in the end, they were all killed by Bai Ma Yicong who led the infantry team led by Yan Gang! There is no way to do this, although the system says that the White Horse can play the characteristics of the troops in the defense of the city, but after all, the strength of the war horse is reduced a lot, and the real battlefield is only used to expel the enemy in the evening.

You must know that those white horses are Gongsun Zhan's baby bumps, and he will be distressed for a long time when he dies! It is worth mentioning that after Guanzicheng was besieged, Gongsun Chan gave a force of 5,000 people to Liu Bei as soon as possible, and asked him to take more care of the city wall! And curious players later found out that those original soldiers had actually been transformed into a special class - white-eared elite soldiers!

Some players immediately thought of the reason for this, according to legend, Liu Bei has always had a force ranging from 3,000 to 5,000 when he started, this army can be said to be unbreakable, unruly, and has been following Liu Bei into Sichuan, and finally handed over to Chen Lai's leadership. Legend has it that this army fought bravely, all of them were good at one as ten, and they would have white hairs on their ears when they fought, so they would be called white-eared elite soldiers!

This force appeared, and it was obvious that the system was deliberately adding weight to Gongsun Zhan. After all, a pipe city that has been taken down the gate, and it is not ordinarily difficult to hold it. Liu Bei led this army to fight very bravely, and was almost invincible on the city wall.

But in a month's time, the soldiers' weapons were damaged, and the ordnance and equipment in the city were consumed, and even the grain and grass were a little insufficient. These situations can be seen from the recent missions released to players, most of the recent missions are to collect grain and grass for points, and if you can provide ordnance equipment, the points are even higher!

In such an atmosphere, many players began to speculate whether Gongsun Zhan's Guanzi City was about to run out of ammunition. After all, once the food and grass are cut off and the materials for defending the city are no longer abundant, when Guanzi City faces the millions of Zhang Chun and Karasuma coalition forces outside the city, it will be a dead end!

At this moment, Xu Yang is in his mansion - that's right, it is a mansion, because of the war, many large mansions in Guanzicheng are no longer inhabited, and Gongsun Zan simply distributed these mansions to these generals. And Xu Yang, as a guerrilla general, was naturally fortunate to have a set of mansions, looking at the generals in the hall, where was there any worry about the lack of food and grass!

As the general of Guanzi City, Xu Yang knew. At the beginning, the black scales had no choice but to launch an exchange between the offensive and defensive sides, but that exchange was not a complete situation. The fire-burning objects in the city were arranged less than half of the city, and the warehouses and armaments had not had time to destroy this incident. At that time, the location of the warehouse was not arranged with fire oil and other materials, so there were still a lot of materials left in the city, and half of the pipe city was burned, but the ordnance materials defending the city were still there!

The reason why he is like this is actually that General Gongsun has an order to paralyze the enemy and let the rebel side relax their vigilance, so that it is possible to give his troops a chance to breathe. After all, even an iron-clad army would not be able to hold on to the city wall day and night, otherwise he would die of exhaustion before the enemy could defeat him!

At present, the defense adopts a rotation system, with three posts a day, and the troops that do not guard the post take time to rest. Unless you receive a first-class military order, you are not allowed to fight! This also created a false impression for the rebels outside the city, that is, the defenders of Guanzi City had gradually shown fatigue under their multi-day onslaught, and they would soon be able to break the city and make meritorious contributions!

"Ladies and gentlemen, we are here to guard the city gate tonight, if you have any opinions, please let me know!" Xu Yang sat on the main seat and asked Gao Chong and the others below.

The location of the gates is always a priority, especially at night. After all, people's vision will be limited after dark, if the enemy really makes any small moves and does not find out in time, then the city gate will leak into the air, and I am afraid that the entire pipe city will be in danger!

"Lord, this is not the first time we have guarded this city gate. It's still the old rule, when the oil is ready, wait for those rebels to move things, as long as they dare to move, we will sit and wait for victory with a little fire! Huang Chen suggested below.

This method is also a method that is easier to use before, pouring fire oil on the heavy objects that block the city gate, because those heavy objects are not afraid of fire, if the enemy really comes to move, the fire oil itself will not leave a hand, and a fire will come from the inside, which will directly burn the enemy crookedly!

"I'm afraid this method won't be used a few times, because the fire oil in our city is a bit in short supply......" Xu Yang shook his head and said helplessly.

Fire oil, this thing is definitely a weapon for defending or besieging a city. After all, after encountering an open flame, it is a sea of fire, and there is a way that water and fire are ruthless, and this fire is basically a war together! The enemy's attack was repelled so many times, and the oil was indispensable! But now that Xu Yang said that the oil was about to run out, all the generals fell into deep thought.

Only Gao Chong seemed to have caught something, and immediately said: "Lord, if the art of war is cloudy, it is real, and if it is real, it is false!" We have burned the rebels with fire oil many times, and presumably they should have sent people to watch near the city gates now. They are not easy to do during the day, and we can see their movements clearly, afraid that they will stare at us at night, as long as we do less than one night of decoration they will come and try to carry the heavy objects under the city gates, this is a place we can use! ”

"Oh? If you take advantage of it, you say come and hear it! For the idea of high charging, Xu Yang suddenly felt a little interesting.

It is not a loss that he is a super-first-class historical general, and this art of war will come as soon as he opens his mouth, and before saying that the battle plan is to quote the classics, he will come to a cloud of the art of war. This is not a forced idea between the players, it is definitely much more high-end!

"Returning to my lord, since the enemy will send people after dark to monitor whether we have set up the city gates, it means that the enemy should not take action after seeing that we have set up the city gates! In that case, why don't we replace the spilled oil with something else? In the dark of night, the eyesight is limited, and it is impossible for the enemy to come forward and take a closer look! If we were splashing a different fluid, it would have had the same effect......" Gao Chong explained his plan.

"Other fluids? Are you water? Xu Yang immediately thought of something that could replace fire oil, but if it was replaced with water, I am afraid it would not be so easy to do. After all, water is not as slippery as oil, and if the enemy really comes forward to check, he will suddenly find that the water dries up quickly, which is embarrassing!

Gao Chong added: "My lord, we can order someone to carry a large barrel with fire oil, and then arrange a small amount of fire oil on the periphery, and replace it with water in the back place!" The amount should be large and sufficient, giving the observing enemy the illusion that we have a very large stock of hot oil. At the same time, the lord can take this opportunity to discuss the matter of fire oil with General Gongsun, presumably by the time the enemy reacts, we will already have a solution! ”

Xu Yang nodded silently, this method is really good. But it's a little more dangerous, if it's really arranged according to what Gao Chong said, the enemy really comes to the city gate at night to act, then tonight's fire is afraid that it won't be lit! However, thinking of Gao Chong's previous sentence - the real is virtual, the virtual is the real, Xu Yang still nodded and agreed!

That night, the troops defending the city on the side of the imperial court can be described as magnanimous! The oil was poured on the weight of the city gate as if it didn't want money, and those who watched from a distance found that the court had used three more barrels of oil on this night alone. This is the amount consumed in a day of guarding the city, although I don't know how the court is so arrogant, but this observer knows that this city gate must be out of play tonight.

Three barrels of fire oil, if it were lit by a fire, I am afraid that thousands of people would not be enough to burn. When the time came, the defenders in the city were alarmed, and the defenders of the city came from the city wall in bursts of projectiles, and in the end, it was definitely the corpses left by their own side that fled in the desert!

The soldier dutifully reported the incident to his superiors, and of course the rebels did not launch any plans to attack the gates that night. Even the players on the rebel side who heard some rumors chose to stop fighting, after all, the NPCs don't fight, and if they go up to fight a little trouble, it's no different from delivering food.

Xu Yang, who was standing behind the city gate, saw all this in his eyes through his peeping eyes, and couldn't help but give Gao Chong's plan a thumbs up......
