"Dong dong dong dong——"

Among the enemy troops outside the city, there was a sound of war drums.

Hou Dan knew in his heart that this meant that the enemy troops outside the city were about to launch an attack on the city.

"Can you hold it?"

Hou Dan swallowed secretly and felt slightly weak.

To be fair, Hou Dan was a fierce and brave general when he was in Longxi. Now, twenty years later, although he is over half a century old and not as brave as before, his familiarity with war is far higher than here.

Everyone.

To be precise, even among the Imperial Guards in Daliang City, there may not be anyone more experienced than Hou Dan.

But the problem is that although Yecheng is not too small, it can only accommodate five or six thousand garrison troops. With this small force alone, if he wants to repel more than 100,000 troops outside the city, to be honest, Hou Dan is under a lot of pressure.

"Woo-wu-wu-"

The trumpet sound representing the siege of the city sounded among the enemy array outside the city.

Suddenly, tens of thousands of grain soldiers rushed toward the east wall of Yecheng in a chaotic manner. The tide-like momentum made Hou Dan, who had been away from war for a long time, feel a little nervous.

"It would be nice if there was a moat..."

He murmured to himself.

Chen Dan, who was standing next to him, heard this and reminded: "Our city does not have a moat, but we have "fire canals" and "fire fields."

"What is that?" Hou Dan was confused.

I saw Chen Dan turning his head sideways, pointing to the city defense map in Hou Dan's hand, pointing to the divided land like fields outside Yecheng on the map, and said: "These long lines are the fire canals.

And these are divided into pieces, which are the fields of fire."

Hou Dan nodded and waited for Chen Dan's next words. Unexpectedly, after waiting for a long time, Chen Dan didn't explain again, so he had to ask again: "That's why... what are Huo Canal and Huo Tian? They are Yecheng's unique defenses."

Means?"

"Yes." Chen Dan nodded, then raised his hand and pointed outside the city, saying: "General, can you see those small ditches about an inch outside the city? They are all made of bricks, stones and cement. These ditches

Directly into the city, as long as kerosene is poured on the ditches in the city, depending on the height difference of the terrain, the kerosene will fill the ditches and fields outside the city along the ditches. Finally, with a fire arrow, the fire will quickly follow the fire ditches

With the spread of fire, no matter how many enemy troops there are, they will not be able to cross this line of defense... General Hou?"

Hou Dan hesitated to speak and looked at Chen Dan. He couldn't help cursing in his heart: There are obviously such powerful defense methods, but you guys didn't tell me? Yes, yes, even though you gave me the city defense blueprints, it's still up to me.

I understand!

Seeing that Chen Dan had gray hair on his temples and was older than himself, Hou Dan finally endured it and suppressed his anger and said, "Why don't you quickly order someone to pour kerosene in the ditch?"

Chen Dan looked at Hou Dan in confusion and said: "General Hou is the defender of our Yecheng right now, so General Hou should give the order."

"I……"

Hou Dan gritted his teeth, turned around and ordered the guards behind him: "Quickly, pour kerosene into the ditch quickly..."

Before he could finish his words, Chen Dan interrupted again: "The effect of kerosene is actually not very good, but I, Yecheng, have diluted kerosene, which is more effective than ordinary kerosene...

"

"..."

Hou Dan turned his head and took a deep look at Chen Dan. He swore that if the official hadn't looked so indifferent and didn't seem to be deliberately playing tricks on him, he would have definitely broken the opponent's nose with one punch.

"Go quickly!"

Hou Dan endured his depression and shouted at the imperial guard soldier.

"Yes!" The Imperial Guard soldier immediately clasped his fists and left.

Seeing this, Hou Dan once again looked outside the city, clenching his fists and feeling a little annoyed.

In his opinion, if he had known that Yecheng had such powerful defense methods, he would definitely have caused heavy casualties to the enemy troops outside the city without even being able to touch the city wall. He didn't want to have to defend for a while now.

Wave, lest the grain soldiers outside the city use the long siege ladder to climb up.

After thinking about it, Hou Dan suddenly had an idea and turned around to ask Chen Dan: "Besides Huo Canal and Huo Tian, ​​does Yecheng have any other means of defending against enemies?"

Chen Dan thought for a while, tapped the city wall with his foot, and said: "Actually, every twenty steps on the city wall of our city, there is a small hollow that allows soldiers to hide in it and follow the shooting holes on the wall.

, use the improved mechanism crossbow box to attack the enemy troops outside the city... This kind of weapon is the most powerful when used at close range, especially for the grain recruits outside the city who do not have armor to protect themselves... General Hou?"

"..." Hou Dan looked at Chen Dan silently, and then shook his head as if frustrated.

At this time, the tens of thousands of soldiers outside the city were getting closer and closer to the city. Although Hou Dan immediately ordered the crossbowmen of the Imperial Guards on the city wall to start shooting, they still could not completely stop these like a tide.

The soldiers rushed to the city to collect food.

Just when Hou Dan was secretly worried, he suddenly saw a pool of blood splashing on the chest of a grain recruiter outside the city.

Before Hou Dan could react, a pool of blood splashed on the chests of the soldiers who rushed to the front. Immediately, these people looked horrified, as if they didn't know what was going on, and they fell to the ground.

He fell to the ground and died with his eyes open.

"Ouch!"

Hou Dan was in high spirits and couldn't help but want to praise the defensive weapons of the Manufacturing Bureau. At this moment, he suddenly caught a glimpse of a line of fire outside the city that spread rapidly towards the distance. In the blink of an eye, it spread to the entire suburbs of the city.

I saw lines of fire crisscrossing each other, and the flames shot up nearly half a foot high, like a field of fire, which was very spectacular.

It's a pity that those grain-recruiting soldiers who were so powerful just now are all caught in the fire field. Some turned into burning people, howling and wailing, and some were directly burned to coke.

"Why? Didn't you say you need time to prepare?"

Hou Dan frowned and asked Chen Dan beside him.

Chen Dan seemed to have thought about this problem. After thinking for a long time with a frown, he suddenly realized: "Oh, by the way, when I learned that the enemy was attacking a few days ago, I, Yecheng, were preparing to test these fire weapons.

Tian, ​​I looked at where maintenance was needed, so I poured some fire oil in advance... Later, when the enemy attacked, I forgot about it."

"..."

Hou Dan took a deep look at Chen Dan, then took a deep breath and turned to look at the enemy troops outside the city.

Although he could not evaluate whether craftsmen like Chen Dan who also held official positions were the best craftsmen in Wei, he could be sure that this group of people was definitely the most careless.

"But then again, this is really a defensive weapon..."
