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

Listening to Ma Jun endlessly introducing his masterpiece, Liu Zheng had already begun to float in his thoughts, and began to think about what the train wheels would look like in the future.

Although he said that he had taken a lot of trains, he really didn't seem to pay much attention to what

the wheels of the train looked like! Because Liu Zheng felt that the wheels of the train were not recessed in the middle, and Ma Jun himself said that because the wheels were recessed, it was easy to overturn when turning.

So now this track can only be straight or not very curved, in order to maintain a certain speed to run safely, if the speed is fast or sharp turns, there is a chance to overturn

!"Oh! I remember!" When Ma Jun was explaining, Liu Zheng suddenly screamed, which scared Ma Jun.

"I don't know what the lord remembered?" Ma Jun immediately stopped his introduction and asked.

Liu Zheng pretended to be mysterious and said: "Well, I seem to have seen something similar in a dream, it seems that the wheel is a roller and then one side is cocked a little."

Liu Zheng pretended to think, and was not sure to describe to Ma Jun a little bit of the appearance of the train wheels in later generations.

Ma Jun's eyebrows were like loaches, moving wildly, thinking about what Liu Zheng said.

Liu Zheng was not in a hurry, and when he finished thinking, he walked in front of the track and observed how the track was repaired.

I have to say that Ma Jun is really a genius, this track is basically what the track looks like in later generations, but it is made of wood, and the bearing capacity should not be very strong, and it needs to be maintained and replaced frequently, otherwise, it will definitely be prone to problems.

"Is that so?" When Liu Zheng was observing the track and carriage, Ma Jun didn't know when to use two bamboos and made two simulated wheels and walked up to Liu Zheng to ask.

Looking at the two wheels in his hand, he could vaguely see the appearance of the wheels of the train in the future, Liu Zheng nodded slightly: "Well, that's pretty much what it looks like!" "

This side is in the track, on both sides!"

Liu Zheng said, describing to Ma Jun how the wheels of the train were sorted in the later generations.

Ma Jun nodded thoughtfully, gave the things in his hands to his assistant, and said to Liu Zheng: "Thank you, lord! Let's get on the car and ride to the headquarters, please!" Liu Zheng

and Ma Jun got into the wooden carriage, waiting for the royal coachman to fix the horses, and with a whip, the sound of driving the horses forward, the wooden rail carriage moved.

As time went on, the horses accelerated, the car ran faster and faster, and there were not too many bumps, the scenery outside the window whirred by, looking at Liu Zheng a little stunned.

"This track is much more stable than a carriage on the road!" Huang Xu sighed.

Ma Jun nodded hurriedly: "Yes, if you run

so fast on the road, the carriage will fall apart, and the butt will not be able to stand it!" Everyone has the experience of going out in a carriage, and when they heard Ma Jun's words, they nodded in approval!

"Minister Ma, you work hard to improve it, so that this track leads to all parts of Dahan, and we will not only go out fast in the future, but also will not be uncomfortable!"

Liu Zheng also joined the chat, couldn't help but encourage Ma Jun, and sighed.

"An old man like me can't withstand long-distance bumps! If Minister Ma can improve well in my lifetime, I will still have a chance to go out and have a look

!" "Hehe, Steward Liu is still young!" Ma Jun was very happy to hear that everyone had great hopes for him

! Because this is because everyone recognizes his strength!

Liu Zheng did not participate in the chat, but looked at the scenery outside the window, and his mind returned to his memories before he came to Dahan.

For so many years, Liu Zheng has not had a moment to immerse himself in the memories of later generations like he does today.

Because without Liu Zheng participating in the chat, he showed that he was thinking, and everyone who knew Liu Zheng's temperament did not continue to chat, so as not to disturb Liu Zheng's thinking.

There was silence in the carriage all the way, and everyone closed their eyes and waited for the carriage to stop.

"Phew~

Hoo~Hoo~" With the coachman's continuous shouting, the horses slowly stopped, and everyone opened their eyes and looked out the window.

"My lord, the place has arrived. Ma Jun said respectfully next to Liu Zheng.

Liu Zheng woke up from the daze and looked at the outside world: "Okay, let's go down." Coming

down, Ma Jun led people to the cement project team.

"Lord, this is the project team you asked us to study better cement at the beginning, and we have experimented with thousands of materials on the basis of your research and development, and it took nearly seven years to find the current formula.

Ma Jun led everyone to the open space, pointed to the thousands of rectangular cement slabs lying on the ground, and said.

When this cement research group was first established, Ma Jun was transferred in, and it can be said that he is the veteran of this research group, and he is doing many things, and many ideas are also put forward by him.

So he is really very clear about this, in front of Liu Zheng and others, talking about the head is the Tao, spitting lotus flowers, and the doubts raised by everyone can be answered without thinking.

"Before I came back, it seemed that a section of the main road was repaired?" Liu Zheng did not forget his anger when he came back that day.

As soon as Ma Jun heard Liu Zheng's words, he immediately replied: "Yes, that section of the road was started together with this track, and that one was reported to the General Staff." "

Apparently he was very aware of these things, and he knew how to say what the lord feared.

"Well, I heard that

it only takes three days to dry hard?" "Yes, the initial development of the product is not only slow to form, but also particularly not strong, it will be broken if it is pressed too much, and it is easy to loosen when washed by rain, after our continuous research, after improving many generations, the latest cement formula has been able to dry in three days, and the same quality cement weight will not be broken."

Hearing Liu Zheng's inquiry, as the main researcher, Ma Jun was very excited about this kind of problem, and immediately introduced to Liu Zheng why the latest research on cement is so easy to use.

"We found a couple of materials to put in and mix the water to make it what it is today, and those things were very easy to find, a couple of plants and juice. "

The more Liu Zheng listens, the more wrong it becomes

! What the hell

? There is a recipe for making

cement and plants? Moreover, the cement road can be dried in three days, and it can directly withstand the smashing of thousands of pounds of heavy objects

? Why did I still travel to the earth in the same dimension?

However, Liu Zheng didn't delve too deeply into this matter, after all, he could cross it, and it was acceptable to have this kind of thing that exceeded or subverted the scope of his nine-year compulsory education!

"Whatever he does, I can cross it, and it's no problem for him to make cement that is better than the next generation!"
