Then, Liu Erdan, you take Qingzhuang and accompany them to Helan Mountain to cut wood and directly build a chicken bus. ”

As he spoke, Zhu Gaoxuan sketched out the unicycle drawings in his memory with a few simple strokes.

"So a wheelbarrow can still be like this?"

"Can this deflection be so large? The straight wheel is also bent, will it break? ”

"This wheel has been made smaller, but it has been widened, will it become heavier?"

Craftsmen are often more pure, and any questions will be raised directly, and they have forgotten the fact that Zhu Gaoxuan is the prince for a while.

Zhu Gaoxuan is also very patient, he will answer if he understands, and let the craftsmen try it themselves if he doesn't understand, without any impatience.

Zhang Jun wanted to interrupt the discussion of these craftsmen several times, but Zhu Gaoxuan glared back.

Soon the craftsmen went home and packed up their tools, and under the protection of Liu Erdan and other strong men, they went into the nearby mountains and forests to cut wood and build cars.

For the sake of safety, Zhu Gaoxuan also asked Zhang Jun to send ten soldiers to protect them with bows and arrows.

There are fierce beasts in the mountains and forests.

Then Zhu Gaoxuan took a look at the manufacture of honeycomb coal and coal stoves, and there were no problems here.

The mixing of coal and loess, the manufacture of coal extractors, and even the construction of coal furnaces have all been produced.

It is basically the same as what Zhu Gaoxuan saw in his hometown when he was a child, although it will be more simple.

"Liu Dagan, briquettes and coal stoves continue to be manufactured, if I don't say stop, I can't stop."

"Little Lao'er will definitely live up to the orders of His Royal Highness King Liang."

The deputy of the fifty-two village is an old Xiucai, a rare scholar in the late Yuan Dynasty and early Ming Dynasty, and when he heard Zhu Gaoxuan's order, he knelt down directly and agreed to the task.

For people with heavy servile thoughts, although Zhu Gaoxuan doesn't like it, he will still use it, such as now.

As long as he gives the task, they will work hard to complete it.

After confirming that there was no problem, Zhu Gaoxuan took Zhang Jun and left directly to the No. 1 blacksmith shop.

……

Jingling...... Jingling......

The crisp sound of percussion came from afar, although it was noisy, but there was a certain rhythm, even if he didn't look at the work site of those craftsmen, Zhu Gaoxuan could imagine that the skills of these craftsmen were extraordinary.

No. 1 blacksmith shop, he also came for the first time, according to Zhu Anlan, this was originally the site of an ordnance manufacturing bureau in Qingxing Mansion of the Northern Yuan Dynasty.

Although it has been destroyed for many years, the foundation is still there, and there is a small iron mine that has been destroyed and flooded nearby.

As long as this iron mine is restored, the self-sufficiency of Lantian farm tools and ordnance will no longer be a problem in a short period of time.

And now, in the blacksmith shop, twenty-six blacksmithing furnaces have started, and the scorching air wave makes Zhu Gaoxuan, who has just stepped into the blacksmith shop, can't help but take a step back and retract the steps he took.

"Your Highness, if you don't go in, let the lower officials watch."

Seeing Zhu Gaoxuan take a step back, Zhang Jun hurriedly persuaded him.

"It's okay, but I didn't expect it to be so hot for a while, so I got used to it."

As he spoke, Zhu Gaoxuan took another step, and the scorching heat made him sweat instantly, you can imagine how hot it is here.

As soon as they saw Zhu Gaoxuan come in, the craftsmen put down their work and saluted.

See ......

"Don't ...... Keep working, be careful! ”

Hearing the sound of striking iron stopping, Zhu Gaoxuan shouted loudly.

The current job of these craftsmen is to "play with fire", and if they stop, there may be an unexpected danger in the mountains.

Jingling...... Jingling......

The sound of striking iron continued to sound, and it became louder, obviously to behave well in front of King Liang.

When Zhu Gaoxuan got closer, he found that these craftsmen were building a big plough rake by themselves, and they all directly built the iron rod in the center first, and now they are basically building spiral blades.

It didn't take long for him to discover a problem.

The size and thickness of the iron rods do not seem to be so consistent.

"Zhang Jun, you bring a few iron rods over and compare them."

"Okay."

Zhang Jun had a lot of strength, and he slipped over with an iron rod nearly two feet long in one hand.

The ten iron rods were quickly moved over, and the contrast was obvious when put together.

Sure enough, the thickness and length are different.

If the specifications are not uniform, once a large rake part is broken, it can only be rebuilt by a fixed craftsman, which is not only time-consuming and laborious, but also may have the wrong size oolong.

Not only iron rods, but also spiral blades are uneven in size and thickness, and even the blades made by a blacksmith are not necessarily uniform.

This increases the cost and difficulty of repairs several times over.

Zhu Gaoxuan frowned, and forcibly asked the craftsmen to stop their work now, change to the assembly line production mode, and patiently read all the work of the blacksmiths.

These craftsmen are very capable.

Three master craftsmen and twenty-three craftsmen presided over an iron furnace, each equipped with more than ten large workers, small workers, and handymen, and they could independently complete the construction of a large rake.

This kind of ability can be regarded as an engineer in modern times, but in the Ming Dynasty, it is only the basic ability of a craftsman at the level of a craftsman.

However, although craftsmen are good craftsmen, the production efficiency is too poor.

"It is imperative to introduce assembly line production."

With a sigh, Zhu Gaoxuan finally returned to his Liangwang Mansion before dinner.

Back in the Liangwang Mansion, Zhu Gaoxuan sorted out some of the rules and regulations and observations he knew, revised, modified, increased, and decreased.

"Whew...... It turns out that assembly line production is not so easy, I took it for granted before. ”

Shaking his sore wrist and looking at the large stack of written papers in front of him, Zhu Gaoxuan couldn't help but sigh.

"Your Highness, you wrote three hundred and seven manuscripts in one night."

Xiao Hongmian, who helped Zhu Gaoxuan sort out the manuscript on the side, accurately reported a number, which was the maid who had followed him since childhood. Because she is beautiful and understanding, Zhu Gaoxuan simply let her be her personal maid.

This is written with a brush, each with at least eight crosses, which is more than 24,000 words, no wonder Zhu Gaoxuan feels that his hand is about to be broken.

Even if he was punished by Zhu Di for copying books, he had never written so many words, let alone written them in one night.

"Your Highness, you have used half an ink strip, let the slave help you soothe and soothe."

The little maid Xiaolan came over, took Zhu Gaoxuan's hand, and gently massaged it.

"I remember when we left the palace, Concubine Ding's mother asked us to bring a bottle of bone-setting wine, and I went to find it."

Xiaomei, another maid, ran out as she spoke, and went to look for bone-setting wine; The other two little girls, Xiaozhu and Xiaoju, were rubbing their wrists, and grinding ink was also hard work, and after grinding all night, their hands were also sore.

Looking at Zhu Gaoxuan, who had dark circles under his eyes, Xiao Hongmian suddenly whispered: "Your Highness, the concubine is waiting for you to bathe and change clothes, right?" ”

"Don't be so troublesome, just wipe your face, it's not early, let's go and rest."
