Three Kingdoms: Me! Liu Zheng! Queen Jing of Zhongshan!

At that time, Liu Zheng thought about it in his heart.

I

haven't heard of this person, but he should be a talent buried by history.

Ma Junzi Deheng was the inventor of Cao Wei during the Three Kingdoms period and one of the most prestigious mechanical inventors in the history of ancient Chinese science and technology!

He restored the guide car, improved the silk weaving machine, invented a keel waterwheel that diverted water from a low place to a high ground, made a rotating stone machine that could continuously fire stones as far as several hundred steps, made a very fine diagram of the water turning a hundred operas, and reformed the Zhuge Repeater.

In the Han Dynasty, so many things were made under the manufacturing level

, and people were very good! In later generations, this was a craftsman of a great country, and he could rub the atomic bomb by hand!

Just after a brief understanding of the situation of Xia Ma Jun, Liu Zheng took people to the logistics department to see what exactly this minister with such powerful technology had made, and to see how he had actually made what he had made.

"Meet the lord!" Ma Jun, who had already received a message from Xiahoulan, took people with him, and waited for Liu Zheng's arrival at the door early, and as soon as he saw the person in front of him, he immediately saluted.

I have to say that Ma Jun has done a really good job in this scene

! But as long as Liu Zheng is a vain lord, he will like this kind of person who can do things!

"Well, please get up." Liu Zheng nodded, smiled at Ma Jun, who was in the lead, and raised his hand to signal everyone to get up.

"Thank you, Lord. "

Minister Ma, the lord wants to come and see the current situation of your logistics department, if there are any new ideas and new projects, I will take the lord to see some of the previous projects.

Xia Houlan walked up to Ma Jun at this time and whispered a reminder.

Ma Jun glanced at Xia Houlan, nodded, indicating that he understood, and then stretched out his hand to Liu Zheng and asked him to come in: "Lord, please come with me." Under

the leadership of Ma Jun, everyone first came to the ordinary construction area.

It is worth mentioning that the logistics department can actually be directly understood as a manufacturing plant, and then it is divided into many project teams, such as the previous cement research project team, radio research project team, etc.

Then there are some building areas, such as public building areas, where basically anyone can come here to place orders, and people can also come to place orders.

There is also a special building area, which supports customization, you can create a sample of the drawings you draw, if you feel that the sample is okay, you can take it to the public building area for them to build, of course, you can also go through the process, enter the professional building area to build quickly, but it needs to be approved by the headquarters staff, and the process is more complicated.

The professional building area is an internal batch building area, which only receives the list with internal approval strips, and ensures the quality and quantity and speed.

The workflow of the logistics department is basically like this, put forward by a certain idea, approved by the branch staff of the logistics department, set up a project team, and then start researching, first they have a simple experiment in their own group, and then take out the confident test product drawings, hand them over to the special building area, take the samples to continue testing, no problem to write out the data and submit it to the branch staff, and if you pass, you can go to the public building area or professional building area, mass production.

Liu Zheng looked at a huge factory building not far from the door, with a few big characters written on it in the ordinary construction area, and many workers were busy inside.

But basically, they are all made of iron and the like, and they make iron products of different shapes.

The sound of clanging bells filled the factory, which made people uncomfortable to listen to, and I felt that my ears were going to be deaf!

Seeing Liu Zheng frowning and uncomfortable, Ma Jun hurriedly took out a few stoppers and handed them to Liu Zheng: "The lord will stuff this into his ears, and he won't be uncomfortable." "

Liu Zheng glanced at it, good guy, the earbuds

! And they are still soft

to the touch! There is a trace of coldness in the ears!

This quality is not bad!"

"Who invented this?" Liu Zheng pointed to his ears and asked loudly Ma Jun, who had already put on the earplugs, asked.

Ma Jun nodded to indicate that he understood, and then pointed at himself.

Liu Zheng gave a thumbs up, indicating that you are awesome

! Then, under the leadership of Ma Jun, he inspected the construction area here, walked out of the public construction area, and pulled out the earplugs, Liu Zheng felt that everyone was clean

! "Ah! It's still not comfortable to wear!"

"Where are we going next?"

Liu Zheng sighed and asked Ma Jun.

Ma Jun hurriedly replied: "Because our construction area is open to the people, and the area is too large, we only put the public construction area in the city, and the rest of the logistics are all outside the city, which is a bit far away, and we need to take a carriage to the logistics headquarters outside the city."

Liu Zheng also knew about this situation, didn't say much, quietly waited for the carriage arranged by Ma Jun to arrive, sat in the carriage and ran for a while, Liu Zheng noticed that the carriage stopped, poked his head out and asked, "Why did you stop... Dig a groove!

" "Railroad tracks?!"

Liu Zheng poked his head out of the carriage and just wanted to ask how to stop, when he saw a railroad track stretching from east to west on the ground not far away, and he didn't see its head until the end of his sight!

"Thank you, lord, for giving this new road a name, and this road will be called a railroad track in the future." Ma Jun is also a clever ghost, and when he heard Liu Zheng's surprised words, he immediately rushed to pat himself.

"Ahem, um, when did you come up with this?" Liu Zheng coughed twice, calmed down, and walked out of the carriage to Ma Jun and asked.

Ma Jun smiled, scratched his head and said: "Hehe, this project is something I've been thinking about for a long time, and I've experimented many times before I started construction the day before yesterday, and it was completed yesterday. "

Who knows, the lord went to the Agricultural College for a whole day yesterday......"

Ma Jun said in the end, a little tasteful, obviously a little resentful in his heart, feeling that the Agricultural College overwhelmed their logistics department.

"Haha, the people take food as the sky, and without the contribution of the Agricultural College, how can you make things with peace of mind? Don't get in the way, don't get in the way!" Liu

Zheng patted Ma Jun and asked him not to take it to heart, and then let him take him to see the railroad track and the corresponding car.

After Ma Jun's introduction, Liu Zheng breathed a sigh of relief and was relieved.

If it weren't for the fact that there are still many defects in this railroad track, it can only walk in a straight line at present, and the speed can't be too fast, Liu Zheng really came because of this Ma Jun!

"What I thought was that we needed too many stones to build the road, even if we researched the cement, it would be much easier to build the road, but it would also take a lot of volume, and it would be very slow to repair, if we could only need two sticks and put them on the ground, so that the carriage could walk quickly, then wouldn't it be much faster for us to build the road?!"

"So I had this idea, originally I just thought about it in my head, but some time ago the research on cement has come to an end, I have free time to start making models, experimenting many times, and finally this framework makes me more satisfied, to the point that it can be used.

"Use strong wood or iron to make a track of uniform thickness, and then make a wheel with a recess in the middle, just enough to get stuck in the main track, and pull it in front with a horse, and you can run

!" "Since yesterday, I have had people experiment no less than 100 times, and there has not been a single accident!" Ma

Jun enthusiastically introduced to Liu Zheng the track he completed by himself and why he had this idea, and asked people to lift the car onto the track.

"Lord, you see, for safety, this car is front and rear four wheels, unlike this carriage, if you lose the horse, it will collapse, if the horse is out of control, you can directly cut the hemp rope, and our carriage will not collapse, wait for it to stop slowly, to ensure the safety of the carriage to the greatest extent.
