Li Chengqian understood, but the others were confused, why didn't they play cards according to common sense?

But seeing that Zhang Zheng didn't mean to explain to them, he had to bury his doubts in his heart.

Zhang Zheng didn't speak again, and Li Chengqian was silent.

The group waited quietly outside the tent for the final result.

After a stick of incense, everyone saw the soldier who led the horse away, and his face was full of excitement.

Before he got close, he shouted loudly: "His Royal Highness the Prince, Zhang Xiannan, it is feasible, it is really feasible." ”

Hearing the shouts of the soldiers, several people outside the big tent showed smiling faces at the same time.

This time the New Year in Chang'an is not a dream after all.

Zhang Zheng muttered, "You can go home." ”

"yes, it's time to go home."

Li Chengqian also sighed.

Although the others did not speak, their thoughts were exactly the same as those of Zhang Zheng and Li Chengqian.

"Old Qian, the blacksmith in the army is at your disposal, before tomorrow, I want the whole army's war horses to wear this kind of iron piece."

Zhang Zheng spoke again, but this time it was a military order.

Now there are seven days before New Year's Day, Tongguan to Chang'an, if it is a normal march, it can be reached in three days.

But this time, Zhang Zheng was going to take an unusual road, and he set aside two days for fear of accidents on the road.

Besides, everyone wants to go home early.

The river is a smooth road, which has never been done in history.

This will open up a whole new way for the army to march in winter, and although there are many restrictions on marching on the ice, it is still a miracle in the military history of the Cold Weapon period.

The blacksmith old money was full of excitement in his heart, and then a wave of excitement rose in his heart.

Because history is about to open a new chapter in his hands.

Old Qian is a blacksmith, and he knows what this piece of iron means.

An inconspicuous piece of iron does not only mean that the Tang Dynasty can transport troops through the river in winter.

It also means that from now on, the number of war horses retired every year in the Tang Army will be much lower than in previous years.

There is no shortage of war horses in Datang, but the number of war horses retired every year due to the wear and tear of horses' hooves is still an astronomical number.

It takes at least three years for a war horse to be raised to be led to the battlefield.

The service time of the war horse is only six or seven years, and the maximum is only ten years.

The eleven or twelve-year-old war horse, for the life of a war horse, is far from being old, but because of the wear and tear of the horse's hooves, he had to withdraw from the army and become a horse.

But with this piece of iron, this situation will be completely reversed.

"Yes, the subordinates have an order, if the horses of the whole army have not put on their shoes before tomorrow, Zhang Xiannan can take the head of his subordinates."

Lao Qian made a military order, excited that he was about to make history.

"It's not that serious, don't take the head guarantee at every turn, what's the use of my head asking for you.

If you can't wear it, you're just going home a few days late. Okay, let's do it, I'll go see the secret art of the Mo family. ”

Zhang Zheng was a little relieved by the old money.

The ancients were sincere, as if their lives were not their lives, and as soon as they opened their mouths, they were willing to sacrifice their good heads.

Lao Qian went to create his own history with an excited heart.

Zhang Zheng pulled a soldier and asked where Li Wucun was going after summoning the carpenter, and then walked slowly towards the carpenter's tent with Li Chengqian.

"I've seen His Royal Highness the Prince, and I've seen Zhang Xiannan."

Entering the tent, there was another wave of greetings.

Li Wucun did not look back, but commanded what the carpenter was busy with, and sawdust flew everywhere.

The progress on Li Wucun's side is much slower than that on the blacksmith's side, but this slowness is only relative.

There are already many wooden strips and squares that are more than two people tall and curved in the big tent, but they have not yet taken shape.

There are many more strips and squares and planks that are shaped from the carpenter's hands and then neatly stacked aside.

Zhang Zheng walked behind Li Wucun with full curiosity.

Li Wucun's voice came: "Let go, don't get in the way." ”

"Ugh."

Zhang Zheng dodged away from Li Wucun, who was holding a bunch of planks in his arms, and touched his nose a little embarrassed.

I didn't expect to be disliked.

However, there really wasn't much place to stay in the big tent, the carpenters were in full swing, and Li Chengqian and Zhang Zheng couldn't see what they were doing.

Li Chengqian also felt a little funny, but he didn't expect that Zhang Zheng, who has always been awesome and coaxing, would also be disliked one day.

After all, he was a friend with a strong enough relationship, so he spoke out to relieve Zhang Zheng and said: "Brother Zheng'er, I can't see anything anyway, let's go." ”

Zhang Zheng could only smile a little embarrassedly, and then turned around and prepared to withdraw from the big tent with Li Chengqian.

"His Royal Highness the Prince, Zhang Xiannan, wait a minute"

Just as the two were about to walk out of the tent, Li Wucun's voice came.

The two paused when they heard this, and cast an inquiring glance at Li Wucun.

"The finished product has come out, I'll take you to see it."

"What?"

"So fast?"

Zhang Zheng and Li Chengqian were a little surprised by Li Wucun's efficiency.

Looking at the wood full of tents, you can know that what Li Wucun wants to build is definitely a big guy, not a gadget like Zhang Zheng that can be knocked out with a few hammers.

And now it is less than two hours before Zhang Zheng gave the order, and the finished product has been made in such a short time.

Even with so many carpenters busy, it's a little too fast.

Li Wucun ignored the surprised expressions of the two and led the two to another tent.

As soon as I entered the big tent, I saw many soldiers under the command of the two carpenters at the head, who were methodically assembling the wood in their hands.

Everyone's job is different, some assemble the wooden squares, some assemble the planks, and finally two carpenters put together the wood that the soldiers put together.

Outside the tent, there were other soldiers who kept transporting polished timber from the camp where Zhang Zheng and Li Chengqian had just come out.

"Damn, this is an assembly line?"

Before entering the door, Zhang Zheng was shocked fiercely.

He actually saw the working mode of the assembly line factory in later generations in Datang.

Li Chengqian asked suspiciously: "What assembly line?" ”

Zhang Zheng pointed to the soldiers and craftsmen who were assembling various parts, and then pointed to the soldiers transporting wood outside the tent and replied: "This kind of work mode is called an assembly line." ”

"The assembly line, it's also appropriate, my Mo family has been using this way of doing things since the pre-Qin period.

The efficiency is naturally much higher than that of ordinary craftsmen, and another advantage is that each part is the same size and is much easier to replace.

However, my Mo family has never shown this method in front of outsiders, and I thought that no one would know about it after the demise of Great Qin.

I didn't think about it, but I was recognized by Zhang Xiannan at a glance, Zhang Xiannan was erudite and talented, and I admired it. ”

Li Wucun also heard Zhang Zheng's exclamation, explained briefly, and then complimented Zhang Zheng.
