Lingnan City East Gate Ferry, the first line of defense.

With the arrival of Cheng Erniu and the rest of the steward, the black armor Xuan barracks of Cao Luxun's department, which had taken a little rest, began to get busy again.

Steward Yu's body is still quite strong, and he is busy shuttling through the line of hundreds of bed crossbows, commanding and explaining how the black-armored soldiers should maximize the lethality of the bed crossbows.

Here, Cao Luxun widened his curious eyes, observing from a distance that Steward Yu was busy before and after, while pricking up his ears to listen to Cheng Erniu's purpose of Steward Yu's move.

I only heard Cheng Erniu say loudly in his voice: "Brother Cao, this is not what I mean, this is my eldest brother's personal order to bring Yu Steward over." ”

Personally instructed by Lord Guo?

The abrupt diaphragm in Cao Luxun's heart was slightly lightened, and then he continued to look at the more than 100 Fengleitang people brought by Steward Yu, and found that they were all repeating an action, that is, soaking batch after batch of rags and broken cotton wool into the wooden barrels in front of them, and after soaking for a long time, they inexplicably fished out these rags and cotton wool from the bucket, and wrapped them in black and wet on the crossbow guns of the same length and thickness as flat shoulders, with three layers inside and three layers outside, three circles on the left and three circles on the right, wrapping the entire crossbow gun tightly from head to toe. It's like the stinky footcloth that the old lady wears.

This can make Cao Luxun dumbfounded, what are Steward Yu and his Wind Thunder Hall going to do? Could it be that a ballista wrapped in rags and cotton wool could sink an enemy ship with a single shot? It's unheard of!

He couldn't help but question Guo Ye, could it be that Lord Guo was also confused? Where is this for the Yu steward to come over and help? That's a disadvantage.

In a hurry, he was about to step forward to stop him, but Cheng Erniu stretched out his hand to stop him and dissuaded: "Brother Cao, my brother-in-law can say, don't force an obstruction on Steward Yu, he is here to help you." ”

"!"

Cao Luxun looked at Cheng Erniu with a gloomy face, and said angrily: "Could it be that wrapping some strips of rags on the crossbow gun and stuffing some broken cotton wool can maximize the power of the bed crossbow?" I think Master Guo was deceived by this rest of the stewardship, and listened to him credulously. Do you want to set up an altar here for me to make a ritual and pray that this black water river god will be mighty and sweep all the more than 200 warships on the water into the bottom of the river? ”

"Uh......"

Cheng Erniu was stumped by Cao Luxun's words, although on the way here, Manager Yu had already mentioned it to him, but he had already forgotten about it.

For a while, I didn't know how to explain to Cao Luxun the intention of Steward Yu and Feng Lei Tang's move.

In desperation, he threw down a sentence: "You wait, I'll call you the rest of the steward." ”

As he spoke, he pulled his leg and ran towards Steward Yu's side.

In an instant, Steward Yu came to Cao Luxun with Cheng Erniu with wet hands, and said with a smile: "General Cao, General Erniu asked the old man to come over and explain to you, hey, the old man had already told General Erniu on the way here, but he didn't think he had forgotten it again." ”

Cheng Erniu scratched the back of his neck and said with a sneer: "You told me, but I forgot it after listening to it, hehe, it's better for you to explain it to General Cao yourself." ”

After listening to Cheng Erniu's words, Steward Yu and Cao Luxun rolled their eyes in unison, this guy is a typical left ear in and right ear out.

Cao Luxun ignored it and asked directly to Steward Yu: "Steward Yu, General Ben is very curious, what are you going to do by wrapping cloth strips and stuffing cotton wool on this crossbow gun?" Don't you tell General Ben that just by making these fancy tricks on the ballista gun, you can easily sink the enemy ship on the Blackwater River with a single shot from the bed crossbow? ”

Cao Luxun's last words are naturally the opposite, how could a sophisticated person like Steward Yu not hear the other party's dissatisfaction?

It naturally sounded a little harsh, but Steward Yu was not angry because of the other party's ridicule, because the other party didn't understand the internal reason. If you want to blame, you also have to blame Cheng Erniu's unremembered head.

Immediately, Steward Yu turned sideways with a smile on the corner of his mouth, raised his hand and pointed to a bed crossbow not far behind him, and said, "General Cao, have you seen the wooden barrel next to the bed crossbow?" ”

Cao Luxun nodded and said, "See, isn't it the wooden barrel you were soaking in rags and cotton wool just now?" ”

"Yes, the mystery is in that barrel!"

Steward Yu smiled and gently waved his hands in front of Cao Luxun's nose and asked, "General Cao, the old man's hands are wet, do you smell anything?" ”

In fact, as soon as Steward Yu came to him, Cao Luxun smelled a strange smell early in his nose, which was very choking. At first, he thought it was because Steward Yu hadn't taken a shower for a long time, which caused a strange smell on his body.

Now after he danced with his hands, he was sure that the source of the smell was not from Steward Yu's body, but from his hands, to be exact, this choking smell should come from the wet liquid on Steward Yu's hands.

So, he nodded his head to indicate that he smelled it, and then asked, "You are talking about the secret lies in the water in that bucket?" ”

"Yes, yes, General Cao is really powerful, you guessed it."

Steward Yu nodded with a smile and said, "But this bucket is not filled with water, but fierce fire oil." ”

"Fierce fire oil?"

Cao Luxun is a knowledgeable person after all, although the three words of fierce fire oil are relatively obscure, and the use is not widespread and popular, but he has still seen relevant records about fierce fire oil in ancient books.

The so-called fierce fire oil, the Eastern Han Dynasty historian Ban Gu recorded in his "Hanshu Geographical Chronicles" that "Gaonu County has water that can be burned".

Fan Yezhi's "Book of the Later Han Dynasty and the Chronicles of the County of the Southern Dynasty" recorded the collection and use of fierce fire oil by the ancients: "(Longevity) There are mountains in the south of the county, and the stone springs are as big as that, and the burning is extremely bright, and it is not edible. The county people call it stone paint. The so-called "stone paint" in the text referred to fierce fire oil at that time.

In ancient times, the common people also used to refer to the fierce fire oil as "a kind of water that can be used for burning".

What exactly is this liquid that can be used for combustion?

When Steward Yu mentioned it to Guo Ye, Guo Ye's eyes lit up, isn't this Nima oil?

Therefore, Guo Yecai so simply and unconditionally trusted Steward Yu to come to Cao Luxun's side to help use the fierce fire oil with the bed crossbow, and maximize the destructive power and effect of the bed crossbow.

As for how to effectively use the fierce fire oil with the bed crossbow, Guo Ye had made a move with Steward Yu earlier.

I only heard that Steward Yu glanced at Cao Luxun's expression, and said in surprise: "It seems that General Cao knows something about fierce fire oil?" The general's erudition surprised the old man a little, haha. ”

Cao Luxun shook his head, said a false praise, and then asked with some puzzlement: "Then what does this fierce fire oil have to do with the bed crossbow projecting crossbow?" ”

Speaking of this, Cao Luxun suddenly remembered a detail of the remaining stewards just now, and suddenly understood and asked: "Just now you soaked all the rags in the wooden barrel, and then wrapped the crossbow guns tightly around and around them, could it be that you want to use the rags and the rags and the rags in the wool to hide the fierce fire oil, and then set it on fire...... And then use the bed crossbow to shoot at the enemy ships on the Blackwater River? The purpose is to burn... Burning the ship? ”

In the end, Cao Luxun was already shocked by this whimsical but not impossible idea!

"Hehe, General Cao is really amazing, and you guessed one or two again."

Steward Yu still had a smile on his face and said: "The old man only discovered the fierce fire oil, and the person who really came up with this earth-shattering plan is not the old man, but Lord Guo." Guo said that today's battle can learn from the Chibi Battle of the Three Kingdoms of Wei, Shu and Wu in the late Eastern Han Dynasty. ”

"The Battle of Red Cliffs??"

Cao Luxun muttered a few words to himself, as if he understood, and nodded in surprise and praised: "Heaven, it turned out to be the burning of Cao Wei's ship in the Battle of Chibi, like, it's really like ......"
