Ma Jun's second apprentice surnamed Chai Mingyu is also Pu Yuan's apprentice grandson. He reminded Pu Yuan, "Many gears on the drawings sent by the sect leader have unique sizes that need to be made individually, and it takes a lot of time to make them, whether they are molds or finished products. So I personally suggest that instead of wasting time like this, it is better to use the ready-made gears in the warehouse instead. Although this is slightly different from the internal structure on the drawing, the effect is just as good. The same can achieve crossbow bolt bursts, and the power is the same. Master, what do you think? “

Pu Yuan was overjoyed when he heard this, "Very good! Just do as you say. ”

Chai Yu didn't know that a few months later, when Pu Yuan reported the process of manufacturing 5,000 ballista carts to the church and asked the church for credit, Chai Yu's replacement of the special gears for the ballista inspired Luan Yi a lot, and he suddenly realized the importance of the word "standard".

Take gears as an example, if the gear manufacturers of Quandahan only make one-inch, two-inch, five-inch, and seven-inch pinions, as well as one-foot, two-foot, five-foot, and seven-foot gears...... There are only these. And what does it mean that all the Han needs to be equipped with gears - clocks, spinning wheels, and even thunderbolts and repeaters can only use these types of gears?

This means that if a thunderbolt's five-foot gear is broken, a repeater can be dismantled at any time, and a five-foot gear can be removed from it and replaced with a thunderbolt, so that the two pieces of equipment will not collapse collectively because there is no material to be prepared.

It also means that in the future production and life, there is no need to keep opening molds and manufacturing all kinds of gears because of the birth of new things-because the gears of the whole Han are the same standard.

And this standard, this size, is the standard.

Let me ask, if Zhuge Liang used standard-size gears when he first designed the ballista car, would it be so complicated to manufacture it? No...... When you need gears, you only need to go to the warehouse of the gear production plant to pick up and use them.

Coincidentally, the same is true for gears, and so should springs, including wheels, screws, nuts...... All of them should be.

"Standard...... It is a booster for the progress of a country's productive forces. In that day's diary, Luan Yi took the lead in writing this sentence, and the next day issued an edict ordering Chai Yu to set official standards for the size, texture and standard of all production utensils and tools in Dahan from now on.

Of course, this is a later story, so I won't say much about it for the time being.

Let's say that the 40,000 Qiang pioneers were violent, and they went straight to the Han army to kill, and when they were within 100 steps, they saw the shield soldiers in front of the Han army array flash to the side, revealing the dense archers behind them, as well as rows of strange cars with strange styles.

A group of Qiang soldiers were wondering the purpose of this car, but they heard the Han soldiers make a string of syllables "fang". Although the Qiang people couldn't understand the meaning of this command, they could guess his general meaning with their buttocks.

"Watch out for the stray arrows!" The leader of the Qiang army, Ang Sheng, shouted. The Qiang soldiers behind him immediately followed the order, leaning forward and clinging to the horse's back to reduce the individual target.

At this moment, the sound of breaking strings "buzzed", and after half a breath, the sky suddenly darkened. Some of the soldiers who had never been on the battlefield also said that dark clouds suddenly came from the sky, and when they raised their eyes, they saw where the dark clouds were, and it was clearly locusts transiting. Then it was unbelievable, where did the locusts come from in the grassland of the cold winter wax moon, take a closer look, and obediently...... Immediately, his face turned pale with shock, and he shouted in a broken voice: "Ah...... That's the arrows of the Han people. ”

Mo said that these new recruits who appeared on the battlefield for the first time were those old Qiang soldiers who boasted that they had fought several tough battles with the Han people, and they had never seen such a dense battle.

The long arrows swarmed and descended into the Qiang array from the sky, leaving no time for the Qiang people to be shocked, and the screams rose with it, and even the floating clouds in the sky shook it. "Ah......h

The front of the church army turned into a Shura hell in an instant.

I saw that the arrows shot by the Han soldiers in the six phalanxes formed six dense striking surfaces about ten zhang wide and nearly one zhang long. Where the arrows rained, there were corpses in one place, each with at least two or three arrows stuck in its body. After a round of projectiles, the crossbowmen under the command of the commander were still throwing arrows diligently, and they continued to dig square unmanned holes in the Qiang people's charging formation.

To use a figurative analogy, if it is said that compared to the arrow array shot by people, the ballista is more shocking. A series of twelve arrows flew into the sky at the same time, and then fell down, forming a huge arrow bridge with countless crossbow arrows combined.

The end of the "arrow bridge" was connected to the Qiang army array, and immediately made a crispy sound like chopping meat, "pop pop ......" The distance between arrows and arrows is not to say that it is a huge person, that is, a bunch of shells are nested in such an arrow array, and the survival rate is not more than one-fifth.

The first wave of arrows killed more than 2,400 people, the second wave killed more than 1,200 people, and the third wave killed more than 1,300 people...... It's like a live slaughter site.

The original "convex" shaped Qiang army formation, after withstanding Huang Zhong's bow and crossbow arrow array, suffered heavy losses and became a "Hui" type. ate a round of twelve rounds of Zhuge Liang's crossbow array, and suddenly it became a "concave" shape in the mouth. Of course, at the moment, this concave looks similar to the convex just now, but if you look down at it from the high altitude of the battlefield, it is not difficult to find that this concave and the convex just now are not the same font size at all.

If the original Qiang army formation looked like the No. 2 word in word at an altitude of 500 meters, then now this convexity has shrunk to the level of "little three".

The number of soldiers and horses was seriously reduced, nearly half of the 40,000 Qiang soldiers were killed or wounded, and the first sword part of the large array was "concave", exposing the Chinese army.

When the Qiang soldiers saw that the ground was full of corpses that had been pierced into a hornet's nest, their hearts and livers were suddenly pulled together. They are afraid, they are not afraid of fighting with the enemy for their lives and dying under the spears of the Han people, but they are afraid that they are so unclear that they have not seen what the Han people look like, so that people will shoot all over the body from afar.

The terrible cry was like the howl of a pregnant wolf in the middle of the night, poking them into the heart, and giving them goosebumps all over their bodies.

So, the Qiang rider pulled the reins violently, began to slow down, and then turned the horse's head and fled backwards in panic. One person retreated and ten thousand people followed suit, and the frightened Qiang pioneers made the most wrong decision again at this time, and actually reduced their speed within the range of the bows and arrows of the church army, twisted and fled, giving the church's crossbowmen a second chance to shoot in vain, so that thousands of people lost their lives under the dense array of arrows on the way back.

The mistakes made by the Qiang pioneers are much more than that. When they retreated, they collided with the 40,000 rear troops who rushed to support and the 50,000 reinforcements led by the leaders of the five tribes of Sister Le, Dangfang, Khotan, Sister Gang, and Beipu.

The two armies and horses were entangled in the center, one advancing and one retreating, unable to advance or retreat, and were in a mess.

Luan Yi was overjoyed when he saw this, how could he let go of such a fighter, and immediately ordered the engineer army to adjust the direction of the thunderbolt projection, and take advantage of the confusion of the enemy army to open fire with all his might.

This time, the Qiang people were not only more numerous, nearly 100,000, but also crowded into a mess. It became an excellent target for the sappers of the church.

The sappers also seemed to see that the opportunity could not be missed, and desperately reloaded the thunderbolt cart, and the levers kept swinging, dazzling, and the overwhelming gourds rose into the air and landed in the densest place of the Qiang cavalry crowd.

"Boom, boom, boom......" The earth shook because of the blasting, and the endless handmelons directly blew off a layer of skin from the ground under the feet of the Qiang rider, and the ground that was frozen hard in winter became soft due to the scorching flames, and at the same time became red and muddy due to the implantation of blood.

A Qiang soldier whose entire right leg was blown off by a handmelon in the blasting was covered in blood, and he fell on his back in a pile of human organs, covering his bleeding wound and howling. While feeling the rapid passage of life, reason told him that staying where he was looking for death, so he began to try to ask for help from the people around him.

He called out a few names, which had been his best friends, but as soon as he could name them, he was shocked to find his best friends not far away—and they fell to the ground with a blue face. Among them, Ai Hu was the most miserable, the whole person was blown off by the waist, half of the worm-like intestines were dragged to the ground, and half of them were missing.

He whimpered, tears streaming down his face and mixing with blood and mud, making his already numb cheeks even more unconscious. He suddenly woke up, knowing that this was not the time to mourn and weep, that he was going to run away, that he was going to retreat to the rear, and he went home, back to the humble tent. He wanted to eat the noodle soup made by his mother......

He began to cry out for help, shouting for help in Qiang, and the words he shouted with all his might were muffled by the rumbling explosions as soon as he came out. Don't say that others can't hear it, even he can't hear it clearly.

In sight, his compatriots scurried around like headless flies, dodging the flowers and fruits of death falling from the sky. But how can they hide, it is too much, too dense.

The haze of death was looming over his people, getting closer, and more and more people were dying. One of the Grim Reaper flowers and fruits that he saw with his own eyes landed at the feet of a compatriot warhorse, then exploded, and then ...... The compatriot and the horse seemed to be caught by a hand, and when he fell, the horse had broken into two sections, and the compatriot squirmed twice on the ground, and then there was no more movement.

"Death is so simple...... Have you forsaken us, O Aquila? The Qiang soldier didn't expect that this sentence with a little indignation and a little resentment was the last word in his short life.

A handmelon landed beside him at this time, leaving his blood on this battlefield forever.

Nearly 100,000 Qiang people, under three consecutive rounds of handmelon blasting, more than 40,000 people died. Three of the leaders of Sister Le, Dangfang, Khotan, Sister Gang, and Beipu were killed on the spot.

The battle was extremely fierce.

The Qiang people's psychological defenses completely collapsed.

Just as man is not afraid of fierce enemies, but he is afraid of the unknown. The continuous explosions reminded the ignorant Qiang people of the punishment of the gods, yes, it is the God of Celestial, only it can control the thunder and lightning in the world, and only he can have the divine power to kill tens of thousands of people in an instant.

"The Han people have been favored by the Heavenly Eagle God." I don't know who was the first to shout such a sentence, and the Qiang people were completely scared. They couldn't even muster up the slightest courage to take a look at the Han army's formation, so they turned around and ran.
