Chapter 510

"When Chang'an city comes to Lanzhou, the boy is naturally free. What my brother worries about is that he will escort grain and grass with the army after entering the prairie." Su dingfang worried.

The expedition Tuyuhun naturally has no brick road, and the advantages of four-wheel carriages have been lost. I'm afraid it's most convenient to use the most primitive two wheel carriages.

Merton nodded. Most of the grassland was grassland, not even the ordinary rammed earth road. The huge four-wheel carriage naturally couldn't bear it.

Suddenly, Merton's eyes lit up and pointed to the strange carriage unloading the stone machine in front. Lang said, "I don't know if such a carriage can satisfy brother su."

Along the direction of Merton's fingers, Su dingfang saw a strange four-wheel carriage. Although this carriage is also a four-wheel carriage, different from ordinary carriages, this carriage has eight wheels, and each wheel is extremely wide, side by side. It's not too much to call it an eight wheel carriage.

"What kind of carriage does it need so many wheels?" Su dingfang was surprised.

Merton explained: "This is a transport vehicle specially developed by my younger brother for the firearms supervisor. Brother Su is an expert in marching. Naturally, we know that if we want to camp, we must sharpen the wooden pile so that we can easily insert it into the ground. This is because the sharpened wooden pile has a small stress area and high pressure. This four-wheel carriage goes the opposite way, adding four wheels to increase the contact between the wheel and the ground and reduce the pressure, Even if it is soft land, it can drive normally and will not sink into the soil! "

Su dingfang's eyes lit up. Isn't it that he can still drive normally on the grassland? He has been worried about entering the grassland to transport grain and grass. The four-wheel carriage in front of him gave him hope.

Merton stretched out his hand and a soldier pulled the unloaded eight wheeled carriage for Su dingfang to watch.

Su dingfang looked at the eight huge wheels and the ruts rolled by the eight wheeled carriage and the ordinary four-wheeled carriage. It was much shallower. He had once expedited Turks with Li Jing. Naturally, he knew that the land on the grassland would be able to bear this strength.

Su dingfang looked at Merton with admiration and said, "Mohist mechanics really deserves its reputation."

As everyone knows, Merton has repeatedly stressed that the core of Mohism is mechanics. Su dingfang is an eye opener today and has really seen the power of Mohism.

"It's nothing. Mohists are studying a new type of heavy-duty vehicle. Once successful, it can carry tens of thousands of kilograms. Even the muddy road after the rain can still walk correctly." Merton proudly said. He is usually modest, but as long as he is designing Mohist knowledge, he never dislikes high-profile.

"Can you walk on the dirt road? I'll look forward to it."

Su dingfang didn't doubt Merton's boasting. Seeing the truck in front of him, he believed what Merton said. Nothing is impossible. "I don't know how many there are in Mojia village? I want them all for my brother." Su dingfang couldn't put it down when he looked at the eight wheeled carriage in front of him.

Merton shook his head and said: "This is a carriage specially designed for the firearm supervisor. At present, there are only ten carriages, but the carriages in Mojia village can be disassembled. The four-wheel carriage and eight wheel carriage are just different sizes of bearing. If brother Su wants to, I can ask Mojia village to work overtime to make the bearing, and send 50 Mojia children to Lanzhou to ensure that they will work for brother Su before going to war Transform enough eight wheeled carriages. "

"Thank you, brother Mo," said Su dingfang gratefully. Today, I was surprised to get the grain transportation strategy and multi wheeled carriages to solve the problem of grassland transportation.

It must be a great achievement to be able to complete the grain transportation task excellently. Su dingfang secretly kept this kindness in mind.

After su dingfang left, Merton looked at the eight wheeled carriage in front of him. Naturally, he could not fight on the battlefield in this war, and the possibility of obtaining military merit was very low. However, for the Mohist school, it was a great opportunity. He wanted to let the world see the powerful power of ink technology.

"Brother Mo, you can start the test." Zu Mingjun said excitedly.

Merton looked around and saw that all the boomers had been assembled and the bowstrings were full. He waited for an order.

He looked at the excited Zu Mingjun and sighed in his heart that in this world, he is not only working hard for his own theory, but also the other hundred schools.

Thinking of this, Merton suddenly brightened up. He went to the new Huihui gun, looked at Zu Mingjun with a smile and said, "today we will let the world see the power of knowledge."

"Launch!" shouted Zu Mingjun.

Buzzing! A recoil gun flew away with 50 kilograms of stones. Soon! There was a loud bang in the distance.

"Five breath time, up to two feet and five!" Zu Mingjun recorded the data in detail.

"Three hundred and fifty steps!" Xue Rengui opened his mouth in shock. The ordinary stone throwing machine was less than 260 steps. Merton only asked the children of the Mohist school to transform, but he suddenly improved nearly a hundred steps. How can he not be shocked.

Merton nodded with satisfaction. The range of the recoil gun of later generations can reach 300 steps by firing 150 kg of boulders. Now it's just 50 kg of stones, up to 350 steps. Although there is still a lot of room for improvement, that's what will happen in the future. It's enough now.

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

Soon, the catapults were launched one by one. In this era, of course, it is impossible to achieve much accuracy. The only way is to test many times and find out the closest number.

"Brother Zu?" just as Zu Mingjun was burying his head in counting, a surprised voice came from behind.

"Huaiyu?" Zu Mingjun raised his head in surprise and looked at the army Han who was covered in mud. After looking at it for a long time, he recognized Qin Huaiyu.

"And brother Cheng and brother weichi, why are you here?" Zu Mingjun didn't understand.

"Merton didn't do it!" Chumo grumbled. After moving bricks for many days, he found how wonderful life in the military camp was compared with moving bricks.

"You have come to repair the city wall!" when Zu Mingjun learned the reason, he couldn't help looking at the three with sympathy.

"Brother Zu, keep an eye on it, or you'll be sold by Morton and count money for him." Wei Chi Baolin said angrily. He was a son of a great Duke. Where did he do such rough work.

Zu Mingjun immediately smiled bitterly. Now he said it was too late. He had already entered the pit.

Merton snorted coldly: "it's not a good habit to speak ill of people face to face!"

The three guys teased him and didn't avoid his face at all.

"Ink offering wine! The city wall has been built. Can we go back?" Qin Huaiyu looked at Merton coldly.

"Of course! You can't do it if you don't go. General Li's military order has come. You can go back to the barracks after you recruit." Merton laughed.

"I knew the general would never forget us!" Chumo suddenly felt like escaping from heaven.

"That's because the great martial arts show is about to begin. Naturally, it's necessary for you three to gather the number." Merton mercilessly revealed the three's good feeling of self.

"Great martial arts!"

The three of them were ecstatic. They didn't care about Merton's sarcasm. They quickly turned back and shouted, "brothers, the martial arts show is about to begin. We'll go back to the camp immediately!"

"Oh!"

Suddenly a burst of liberation cheers came, and the three hundred team gathered at the fastest speed. Under the leadership of Qin Huaiyu, they left without looking back.
