After exchanging a few words with Li Guangbi, Ouyang Fei said: "Lord Li, we have few soldiers, and it is not advisable to defend the city to the death, and we need to take the initiative to attack to have a chance of victory." ”

"My metal storm has just appeared, the Wolf Tooth Army has not seen it, its killing efficiency will definitely make the Wolf Tooth Army horrified, once the Wolf Tooth Army is in chaos, it is the time for our army to attack, take advantage of the chaos to attack, there will be a gain. ”

"This ......"

Li Guangbi stroked the short beard under his chin, did not dare to make a decision easily, and after thinking for a few breaths, he said: "Ou Daxia, after all, this matter is related to the lives of the soldiers and civilians in my Taiyuan city, I wonder if you can let me see the power of the metal storm first?"

Ouyang Fei and Li Chengen looked at each other and smiled, and said, "I was about to ask the adults to take a look, and I also asked the adults to order the soldiers to open the city gate and allow them to go down to the city and lay down the mechanism." ”

Li Guangbi nodded, and instructed his soldiers: "Open the city gate." ”

Immediately some of the soldiers ran into the cave, took off the great latch, and opened the gate.

"Lord Li, please. ”

"Please. ”

The group walked out of the city gate, and there was an open field outside the east gate that stretched for several miles, and Ouyang Fei began to look for a suitable place to place the heavy machine gun after walking out of the city gate.

After going forward for more than 100 meters, I finally took a fancy to a small hill with a slightly flat top, and the height was just right to be level with the cavalry.

If it is completely on flat ground, the muzzle of the cavalry gun needs to be slightly upward, so that the penetration effect of the bullet will not be exerted, and this height is just right.

"Place the trap on that hill!" Ouyang Fei said to the Tiance general who was carrying a heavy machine gun behind him.

"Yes. ”

That day, the strategist put the heavy machine gun on the hill, and the five bags of bullet chains were stacked on the side of the heavy machine gun, Ouyang Fei personally adjusted the direction and angle of the heavy machine gun, held the gun handle and moved left and right, without any hindrance, and nodded with satisfaction.

Li Guangbi, Li Chengen and the others stood aside and watched Ouyang Fei tinkering, and they didn't make a sound, only to see him carefully take out a bunch of yellow, orange and orange copper pills from a sack, pull up the top and stuck it in the mechanism.

Immediately, Ouyang Fei turned his head to the Tiance soldier who was fighting against the machine gun just now and said: "This brother, when the big battle starts and the metal storm is launched, you will be responsible for smoothing this belt, don't let it roll up or jump around, you must let it enter the mechanism smoothly, just ......like this."

After watching Ouyang Fei's demonstration, the soldiers hugged their fists that day and said, "I understand, Ou Daxia rest assured." ”

After Ouyang Fei finished speaking, he turned his head to Li Guangbi and said: "I didn't think about it just now, and I asked Master Li to send someone to send two Hu beds over after a while, this mechanism is a bit short, if you keep squatting to control, it will be a little inconvenient." ”

The so-called Hu bed, which is a common folding stool in later generations, is also called Maza, Li Guangbi nodded and smiled: "No problem, it's just a trivial matter." ”

Ouyang Fei nodded, and then beckoned to the Tiance soldier who was guarding a large wooden barrel behind him, holding a scoop in his left hand and a hollow bamboo tube in his right hand: "Brother, come here, I'll teach you how to irrigate." ”

The wooden barrel was very large, and could hold more than a cubic meter of water, almost more than a ton, and it was carried by four Tiance soldiers like a sedan chair.

The M1917 Browning Heavy Machine Gun has a total volume of 3.3 litres, and when about 400 rounds are fired continuously, the water is heated by the barrel and gradually reaches the boiling point, turning into water vapor and escaping, and then about 1.7 litres of water will evaporate for every 1,000 rounds fired.

And the barrel is located at the bottom of the sleeve, so if you shoot up to two thousand rounds of bullets, you have to refill the water, otherwise the barrel will come out of the water, causing redness and softness.

Ouyang Fei opened the water injection port above the back of the sleeve, and motioned to the Tiance soldier who took the water scoop to fill the water, and the Tiance soldier cut the front end into a pointed bamboo tube obliquely inserted into the water injection port, and then poured the water in the water scoop from the top of the bamboo tube, and soon, the sleeve was filled.

Ouyang Fei reminded: "This brother, during the battle, this mechanism needs to be added with water at any time, probably after hitting two thousand projectiles, it needs to be added once, so you must move quickly, or the Wolf Tooth Army will rush up, understand?"

That day, the strategist nodded solemnly and said, "I understand, when the time comes, let a brother be responsible for scooping water, and I will hold the bamboo tube, so that the speed can be accelerated a lot." ”

"Well, yes, remember, you don't have to make sure you don't spill a drop, you just have to fill it with water as fast as you can. ”

The water-cooled sleeve is equipped with an exhaust port that can exhaust water vapor, so it will not cause excessive sleeve pressure and cause the sleeve to break.

After making all the preparations, Ouyang Fei squatted behind the machine gun, grabbed the grip, pulled the bolt and loaded it with a "click", and then pointed the muzzle of the gun at a small mound dozens of feet away.

The sighting device of the heavy machine gun was less elaborate and larger, with a large crosshair ring mounted a little in front of the grip.

"Ladies and gentlemen, I'm going to launch a metal storm on that mound now, you can feel the power of the metal storm first, but this mechanism is loud when it is activated, so you should be prepared first, don't be alarmed. ”

Hearing this, everyone was refreshed, and they focused on the machine gun, Ouyang Fei turned his head to see that the "ammunition man" was ready, so he looked at the big cross crosshair, pointed the center of the crosshair at the highest piece in the middle of the mound, and pulled the trigger.

"Dada......"

The arrogant roar of the heavy machine gun was heard for the first time in this era more than 1,200 years before the heavy machine gun was born.

The people in the city were alarmed by the thunderous explosion, and asked the Tang soldiers if it was the Wolf Tooth Army.

When I heard the soldiers say that it was Lord Li who was testing a powerful weapon against the Wolf Tooth Army with the martial arts heroes, I was relieved.

Hearing that this weapon is so big, it must be a big killer, and the people can't help but have more confidence in being able to repel the wolftooth army and defend Taiyuan City.

Outside, Li Guangbi and the others, looking at the mound over there with dirt splashing, smoke and dust, and becoming shorter at a speed visible to the naked eye, couldn't help but be stunned for a while.

The gunfire rang out for nearly a minute, and with the strafing just now, four or five hundred bullets had already been spilled out, and when the exhaust port of the water-cooled sleeve began to emit water vapor, Ouyang Fei let go of the trigger.

And that small mound has been completely flattened, there is silence in the field, and the falling needles can be heard, Ouyang Fei turned his head to look at the people who were collectively stunned, the corners of his mouth hooked a smug smile, and said, "Everyone, how is it?"

Li Guangbi and Li Chengen came back to their senses at this time, they ignored Ouyang Fei for the time being, and everyone ran towards the mound together.

"Just here...... Is there a mound that is more than two feet high?" After a while, Li Guangbi said to Li Chengen with a trembling voice, which was excited.

“......”

Li Chengen nodded distractedly, Li Guangbi took a deep breath, turned to the herald behind him and said categorically: "The two thousand soldiers who ordered the town to defend the eastern city were all abandoned to defend the city wall, and the cavalry all got on their horses and lined up here." ”

"Yes. The herald's butt was on fire and he turned and rushed towards Taiyuan City.

After giving the order, Li Guangbi couldn't help laughing loudly: "Hahahaha...... It's a metal storm, it's really powerful! With this artifact, why can't you fight off the wolf's teeth?"

"What's going on here?"

As soon as Li Guangbi's words fell, everyone heard a crisp shout from the side, and turned their heads to look, but saw a black and white figure performing light skills, coming quickly.

More than a mile behind the figure, a group of warriors in armor and swords and shields were running wildly from the north.

Li Chengen smiled at Li Guangbi and said, "The Cangyun Army has arrived, and now everything is ready, just waiting for the wolf's teeth." ”
