So when the Mongolian army under the city began to tie up this kind of "gathering ten thousand enemies" and threw it towards the city.

Although their hit rate is still outrageous, the ten thousand enemies who fell on the bedside sporadically still blew the city to suffer heavy losses.

And not only that, the Mongols' combat methods are becoming more and more refined! Before this, they will ignite twenty thousand enemies before launching.

In this way, even if several people use charcoal to ignite the fire at the same time, the time of the explosion will be difficult to control.

At this time, when the Mongolian army discovered that they only needed to ignite a fuse, it became very easy to accurately control the detonation time.

They even intentionally made the fuse length a little shorter, so that the ten thousand people flying out would detonate in the air near the city before they fell to the city! Under this situation, there were only more than 30 Mongolian army trenchers left.

However, they were using their fast learning speed to quickly increase the power of their weapons! At this time, Hai Mutang saw the soldiers on the city and were hit hard by the explosion one after another, and finally realized that Fancheng was on the verge of despair! If she continued like this, she would be killed by more than two thousand soldiers in her hands in less than two hours! But if she led her troops to retreat from the city, the Mongolian army would then use this gap to quickly board the ladder and occupy the entire city wall! Not only that, when the opponent mastered this tactic of gathering ten thousand people, the street fighting tactics and defensive fortress she laid in Fancheng would also become vulnerable.

Now the enemy has such weapons. When they occupy the city wall, as long as they assemble a few catapults on the city wall with accessories, all the fortresses in Fancheng will become coffins for burying the soldiers! When they think of this, Hai Mutang knew that if she didn't make a decision immediately.

Every minute and every second she hesitated, she had to compensate the warrior's lives! So Hai Mutang gritted her teeth and issued an order!... For safety reasons, the molten bottle stored in the cellar under the city was activated again.

They were quickly transported to the top of the city by soldiers.

After igniting it, he was thrown into the trench below the city.

The trench under the city was cleaned up again by the civilians in Fancheng last night.

It was filled with dry firewood soaked in grease, and a large area of ​​Mongolian army's corpse was also placed on it.

According to Hai Mutang's previous plan, once the situation in Fancheng is in crisis.

She would immediately order the trench to ignite and turn it into a sea of ​​fire.

After this, these dry wood and grease will try to extend the burning time of the flame.

During this period, after the Mongolian army's corpse was burned by fire, the large amount of corpse oil refined will also make the sea of ​​fire under the city burn more and more lasting.

But Hai Mutang didn't expect that she had used this method so quickly, and she did it in desperation to delay time! When dry firewood in the trenches under the city was ignited one after another, and the blazing flames immediately rose into the air.

Hai Mutang immediately ordered the entire army to retreat from the city! The flames churned in the trenches outside the city, which allowed them to take advantage of this period of time to temporarily avoid the killing of tens of thousands of enemies in the city.

At this time, Hai Mutang knew clearly... Fancheng could not be defended no matter what!... "Immediately send flag words to Xiangyang, and ask them to send a boat to come over quickly to pick up the people across the river!"

At this time, Hai Mutang quickly ordered the adjutant beside him.

Now there are more than 70,000 people in the city, and she cannot hand over these people to the Mongolian army behind her! After that, Hai Mutang immediately explained to the artillery commander Wu Qijun, and she prepared an emergency retreat plan in advance.

In this situation, the fire in the trench can burn for about an hour.

After that, Hai Mutang used all the molten bottles and allowed the fire to last for another hour.

After two hours, when the flames under the city were extinguished, the city had to send troops to guard again. That was the time for heavy casualties! However, even if their fleet only had to travel between the Han River and the river surface was not particularly wide, the number of people was too large! In this case, Hai Mutang was determined to use all his strength to ensure that all the people in Fancheng retreated.

So how to fight next becomes a headache... The retreat time is not enough! Now all the artillery on the top of the city is striving to lift it under the city with the efforts of the soldiers.

After the Tongzhou field artillery was disassembled into several large pieces, its weight immediately dispersed.

Because the sixteen-pound cannon itself is not heavy, it is not difficult to get down to the city.

Even if the artillery has to be transported to the city and continue to fire, they must do so.

Because the city wall where the artillery is now located has become the focus of the enemy's attention.

Now the city wall is blown away by thousands of enemies, and there are almost no corners that can be hidden.

At this time, Wu Qijun also knew that the situation in front of him was in danger! He saw him saying to Hai Mutang with a serious face: "Although the enemy's offensive is fierce now.

But I estimate that the number of ten thousand enemies on the Mongolian army is not enough to keep them in such a throwing density."

"So when they find that our defenders on the city have retreated, the Mongolian army will immediately stop attacking and wait for the flames to burn out... Then I will pull the cannon up and continue to attack!"

"What a joke?

If you don’t need two rounds of cannons to hit you, you will be gone!”

At this time, when Hai Mutang heard Wu Qijun’s plan, he immediately knew that there was great danger in it.

She stared at Wu Qijun and shouted: "You are useless to do this!"

He saw Hai Mutang holding Wu Qijun's collar hard and shouting to him: "Take out the flowering bullet and blow up all the horse paths on the city wall for me... and leave one of the north gate."

"Then you put the artillery on the Cross Street and block the three gates on the east, west and north sides of Fancheng."

“I will hold on with the soldiers in the city until the last moment, and wait until the casualties are almost overwhelmed.

I took everyone down to the city and blew up the last horse path."

"In this way, even if the enemy occupies the city wall, they will not be able to enter the city quickly. You can use artillery to block the city gate so that time can be dragged down... We have to send out more people before Fancheng falls!"

“…You really are there!”

At this time, Wu Qijun looked at Hai Mutang in surprise.
Chapter completed!
