"From Chang'an City to Lanzhou, the kid is naturally unhindered, and what my brother is worried about is that after entering the prairie, he will escort the grain and grass with the army." Su Dingfang said worriedly.

The expedition to Tuyuhun naturally no longer has the convenience of brick roads, and the advantages of four-wheeled carriages have been lost, and I am afraid that it is still necessary to use the most primitive two-wheeled vehicles.

Merton nodded, most of the grassland was grass, not even ordinary rammed earth roads, and the huge four-wheeled carriage naturally couldn't bear it.

Suddenly, Merton's eyes lit up, and he pointed to the strange carriage in front of him that was unloading the trebuchet, and said loudly: "I don't know if such a carriage can satisfy Brother Su." ”

Following the direction of Merton's finger, he saw a strangely shaped four-wheeled carriage in front of Su Dingfang's eyes, although this carriage is also a four-wheeled carriage, unlike ordinary carriages, this carriage actually has eight wheels, and each wheel is unusually wide, two by two, it is not an exaggeration to call it an eight-wheeled carriage.

"What kind of carriage is this, and it needs so many wheels?" Su Dingfang said in surprise.

Merton explained: "This is a transport vehicle specially developed by the younger brother for the firearms superintendent, and Brother Su is a marching expert, so he naturally knows that if we want to set up camp, we must sharpen the wooden stakes, so that they can be easily inserted into the ground, this is because the sharpened wooden stakes are small and the pressure is large, this four-wheeled carriage is the opposite, adding four more wheels to increase the contact between the wheels and the ground, reducing the pressure, even if it is soft ground, it can drive normally, and it will not fall deep into the soil!" ”

Su Dingfang's eyes lit up, isn't it still possible to drive normally in the prairie, he has been worried about entering the prairie to transport grain and grass, and the four-wheeled carriage in front of him made him see hope.

Merton stretched out his hand, and a soldier pulled the eight-wheeled carriage that had been unloaded for Su Dingfang to watch.

Su Dingfang looked at the eight huge wheels, and then looked at the ruts between the eight-wheeled carriage and the ordinary four-wheeled carriage, and it was really much shallower. He had accompanied Li Jing on an expedition to the Turks, so he naturally knew that the land on the steppe would definitely be able to withstand this force.

Su Dingfang looked at Merton with admiration and said, "Mojia mechanics really lives up to its reputation. ”

As everyone knows, Merton has repeatedly emphasized that the core of the Mo family is mechanics, and Su Dingfang is also an eye-opener today, and he has truly seen the strength of the Mo family.

"Isn't that nothing? The Mo family is working on a new type of truck, which, once successful, is enough to carry tens of thousands of catties, even on muddy roads after rain. Merton said proudly, he is usually modest, but as long as he designs Mohist knowledge, he never thinks it is high-profile.

"Can you walk on dirt roads? That brother is going to look forward to it. ”

Su Dingfang did not suspect that Merton was talking big, and when he saw the truck in front of him, he believed what Merton said, and nothing was impossible. "I don't know how many eight-wheeled carriages there are in Mojia Village? I want it all for my brother. Su Dingfang looked at the eight-wheeled carriage in front of him and suddenly couldn't put it down.

Merton shook his head and said: "This is a carriage specially designed by the younger brother for the firearms superintendent, there are only ten carriages at the moment, but the carriages in Mojia Village are all disassembleable, this four-wheeled carriage and eight-wheeled carriage are just different in the size of the bearing shaft, if Brother Su is interested, the younger brother can let Mojia Village work overtime to catch up with the bearing axle, and send fifty Mo family children to Lanzhou to ensure that before the battle, enough eight-wheeled carriages will be transformed for Brother Su." ”

"Then thank you Brother Mo for being a brother." Su Dingfang said gratefully. Today, it is a surprise to be able to get a grain transportation strategy and a multi-wheeled carriage to solve the problem of grassland transportation.

Being able to complete the task of transporting grain excellently must be a great achievement, and Su Dingfang secretly remembered this favor.

After Su Dingfang left, Murton looked at the eight-wheeled carriage in front of him, he naturally couldn't go to the battlefield to fight in this war, and the possibility of getting military merits was very low, but for the Mo family, it was a great opportunity, he wanted everyone to see the powerful power of ink skills.

"Brother Mo, it's time to start testing." Zu Mingjun said excitedly.

Merton turned his head to see that all the return cannons had been assembled, and the bowstring was full, just waiting for an order.

He looked at the excited Zu Mingjun, and sighed in his heart, how can he not only think about his own doctrine in this world, but also the other hundred schools.

Thinking of this, Merton's heart suddenly brightened, and he walked to the new return cannon, looked at each other with his ancestor Mingjun and smiled: "Today, we will let the world see the power of knowledge." ”

"Launch!" Zu Mingjun shouted.

Buzz! A return cannon flew away with fifty pounds of stones, and it was very fast! There was a loud bang in the distance.

"Five breath time, up to two zhang five!" The ancestor on the side recorded the data in detail.

"Three hundred and fifty steps!" Xue Rengui on the side opened his mouth wide in shock, the farthest of an ordinary trebuchet was only about two hundred and sixty steps, and Mo Dun only let the Mo family disciples transform and suddenly improved nearly a hundred steps, how could he not be shocked.

Merton nodded with satisfaction, the range of the return cannon in the future can reach a distance of three hundred and fifty pounds, but now it is only fifty pounds of stones, reaching three hundred and fifty steps, although there is still a lot of room for improvement, that is the future, and it is enough for now.

"Continue the experiment and raise the elevation angle by five degrees." Ancestor Mingjun shouted.

Soon, one trebuchet after another was launched, and in this era, of course, it is impossible to be very accurate, and the only way is to test it many times to find the closest number.

"Brother?" Just as Zu Mingjun was immersed in counting, a surprised voice came from behind.

"Huaiyu?" Zu Mingjun raised his head in surprise, looked at the military man covered in mud in front of him, and recognized it as Qin Huaiyu after looking at it for a long time.

"And Brother Cheng and Brother Wei Chi, why are you here?" The ancestor was puzzled.

"It's not a good thing that Merton did!" Cheng Chu silently complained and was angry. He moved bricks for many days, and then he realized how wonderful life in the barracks was compared to moving bricks.

"You've come to repair the walls!" After Zu Mingjun learned the reason, he couldn't help but glance at the three of them sympathetically.

"Brother Zu must be careful, otherwise he will be sold by Merton and count the money for him." Yu Chi Baolin said hatefully, where did he do such a rough job as a dignified son of a prince.

Zu Mingjun suddenly smiled bitterly, now it is too late to say that he has already entered the pit.

Morton on the side snorted coldly and said, "It's not a good habit to say bad things about people in person!" ”

The three guys mocked him and didn't avoid his presence at all.

"Ink Sacrifice Wine! The walls have been built, can we go back? Qin Huaiyu looked at Morton coldly.

"Absolutely! You just can't leave it, General Li's military order has already arrived, and Zhao'er can go back to the barracks. Merton laughed.

"I knew the general would never forget us!" Cheng Chumo suddenly had a feeling of escaping.

"That's because the big martial arts show is about to start, so naturally the three of you are indispensable to make up the numbers." Merton was merciless in debunking the trio's self-good feelings.

"Great Martial Arts!"

The three of them were immediately ecstatic in their hearts, and they didn't care about Merton's sarcasm, and hurriedly turned around and shouted: "Brothers, the big martial arts show is about to begin, let's go back to the camp immediately!" ”

"Oh!"

Suddenly, a burst of liberation cheers came, and the three hundred-person teams assembled at the fastest speed, and under the leadership of Qin Huaiyu and the three of them, they left without looking back.
