The sniper starts from the bright sword escape period

Chapter 410 Baili Xiu's Ping Xiong Policy
However, if someone eavesdrops, especially Zhu Yuanzhang, he doesn't care much!
After all, it depends on Zhu Yuanzhang whether Bailixiu's grand plan to pacify the Huns will be implemented in the end.

So Bai Lixiu just glanced at the screen, then glanced at the nervous prince Zhu Biao, and continued:

"The reason why the Huns couldn't be wiped out was mainly because they could come and go freely on the grasslands on horseback, and Ming's army had no danger to defend on the grasslands, so even if the Huns couldn't beat them, they could still escape on horseback and wait until Ming Dynasty If the army is not prepared to launch a sneak attack, if the Ming army has a city on the grassland, then there is no need to worry about the counterattack of the Huns!"

It's just that when Bailixiu's idea of ​​building a city on the grassland was mentioned, the light in Zhu Biao's eyes, who was still looking forward to it, immediately dimmed. With the demeanor of the fairy family shown, it is estimated that Bailixiu at this time has been driven out of the palace by Zhu Biao.

So at this time, Zhu Biao replied politely because of Bailixiu's previous methods:
"Building a city on the grassland, sir, is fantastic! Not to mention how much it costs to build a city, the transportation of materials for the construction of the city and the interference and destruction of the Huns have to make it come to an end!"

After all, it is not that no one wants to build a city on the grassland, but not to mention the interference of the Huns during the construction, it is difficult to transport the materials used to build the city. There is no stone to be mined, so it is a dream to build a city on the grassland.

Although Zhu Biao's eyes were full of disappointment, Bai Lixiu still said indifferently:

"It is precisely because it is difficult to build a city on the grassland that I sent these two things to His Royal Highness the Prince!"

Speaking of which, Bai Lixiu pointed to the carriage parked at the gate of the Prince's Mansion, and Bai Lixiu pointed to the carriage and said to Zhu Biao:

"Although the four-wheeled carriage seems to have only two more wheels than the two-wheeled carriage, its carrying capacity is more than three times that of the two-wheeled carriage. Similarly, a horse-drawn two-wheeled carriage can pull a thousand catties, so pulling a four-wheeled carriage It can pull three thousand catties!"

Bailixiu is not lying. You must know that Bailixiu uses steel roller bearings in this four-wheeled carriage, so the friction between the wheels and axles is stronger than that of wooden bearings in two-wheeled carriages. Compared with the sliding friction, the reduction is not a little bit.

In addition, the horse pulling the two-wheeled carriage not only needs to provide the traction for the carriage, but also bear part of the weight of the two-wheeled carriage, so this is equivalent to pulling a two-wheeled carriage, that is, moving forward with a load.

But the four-wheeled carriage is different. The goods on the carriage are completely shared by the four wheels. Therefore, the horse pulling the carriage only needs to bear the traction of the carriage. Compared with the two, the four-wheeled carriage is naturally much easier. up.

However, when the two-wheeled carriage and the four-wheeled carriage climb hills, their load capacity is similar.

But is there an uphill on the prairie?If there is, it is not a prairie!
Sure enough, after Zhu Biao heard the benefits of the carriage, he thought of the time when Bai Lixiu asked him how much the mirrors on the carriage were worth, and he also understood that with the financial resources provided by selling mirrors, and the addition of the carriage With the transportation capacity provided, it may not be impossible to build a city on the grassland.

Thinking of this, Zhu Biao couldn't help feeling a little happy, but then he said:
"But what should we do if we encounter a sneak attack by the Huns?"

When Bai Lixiu heard Zhu Biao's question, she shook her head helplessly. It was obvious that Zhu Biao had never fought a battle, so she immediately explained patiently:
"In addition to the high transport capacity, these four-wheeled carriages are also particularly stable. If there is an enemy attack, as long as dozens of four-wheeled carriages are connected end to end, a solid temporary city wall can be formed to deal with the cavalry charge of the Huns. Already!"

When Bailixiu said this, he looked at the screen in the living room again, and then said:
"Presumably His Royal Highness the Crown Prince cannot be the master of such important matters alone, so let's discuss it with His Majesty the Emperor first! I have something to do and I will stay soon! If the discussion is completed, I will go to the north of the city to find my servant!"

After all, Bai Lixiu got up on her own without waiting for Prince Zhu Biao to reply, and then jumped onto the wall of the East Palace with just a light leap, and then leaped out of the palace with a few more jumps. Can't react.

After Bailixiu left, Zhu Yuanzhang came out from behind the screen. At this time, Zhu Yuanzhang was over fifty years old. According to history, Zhu Yuanzhang would live a good life for at most ten years.

After Zhu Yuanzhang came out, he came to the four-wheeled carriage that Bailixiu left in front of the East Palace Prince's Mansion and looked up and down.

The steering mechanism of the four-wheeled carriage is also very simple, so Zhu Yuanzhang can see it at a glance, and can understand its principle, so Zhu Yuanzhang immediately sighed:
"The steering mechanism of the four-wheeled carriage is so simple, why has no one thought of it before!"

You know, as the emperor, Zhu Yuanzhang has also seen other craftsmen make four-wheeled carriages, but that kind of four-wheeled carriage can only go forward and backward, and it is extremely troublesome to turn. If you are not careful, the wheel will be damaged ruined ending.

After all, Zhu Yuanzhang also directed people to lead the horses pulling the four-wheeled carriages and let them circle around in the courtyard in front of the East Palace Mansion.

And this time, Zhu Yuanzhang discovered another feature of the four-wheeled carriage left by Bailixiu, that is, there was no creaking sound.

Of course, this creaking sound is naturally the sound made by the friction between the axle and the wheel.

You must know that there were no ball or roller bearings in ancient times. The axles and wheels of all carriages were either connected by two metal rings with some lubricating oil, or they were hard ground with wood.

But if the carriage really runs at a speed of [-] to [-] kilometers, it will be easy, so under such sliding friction, it will heat up and wear and make creaking sounds, which is naturally nothing more than normal.

So when Zhu Yuanzhang didn't hear the sound, he immediately focused on the axle of the four-wheeled carriage, and then saw the roller bearing specially made by Bailixiu on the axle.

The appearance of roller bearings naturally once again made Zhu Yuanzhang sigh that this carriage was well-made.

But when Zhu Yuanzhang took Zhu Biao to study the four-wheeled carriage that Bai Lixiu made casually, Bai Lixiu had already returned to the small courtyard where he rented.

However, as soon as he returned to the small courtyard, there was a knock on the gate of the courtyard, which made Bailixiu depressed. Did Zhu Yuanzhang figure it out immediately?
But when Bai Lixiu opened the courtyard door, she realized that it was Matchmaker Cai who knocked on the door.

When Matchmaker Cai saw Bai Lixiu, she asked:
"Have things been settled? As soon as Aunt Zhang at the door said you were back, I came to look for you!"

When Bai Lixiu heard Cai Matchmaker's words, she immediately asked:
"I don't know if Mrs. Cai wants to ask me for something?"
