The more powerful the top powerhouse who is above everyone else, the more difficult it is to maintain the stability and sanity of being a "human".

This is also very easy to understand.

All the people you see are like ants that can be crushed to death with one hand. Any attack they have on you is not painful, and when your breath and sneeze can bring them ruin, it is difficult for anyone to see themselves as part of this group and integrate into it in this situation.

So, the stronger the person, the easier it is to go crazy.

Twelve out of ten madmen who are in charge of "healing" by the "Heavenly Doctor" are all of them.

Yin Cheng really didn't want to see her brother in this life also go in this direction.

He no longer sees other people as human beings, if he no longer treats himself as human beings, he solves problems in the way God does to ants. Yin Ji could only fulfill her duties and "treat" him in the way of a heavenly doctor.

The "Heavenly Doctor" is not a gentle angel in white, and the patients she faces are not pitiful lying on the hospital bed, they are basically S-level wanted criminals, and special forces are sent to arrest them.

This system of arrest and treatment is destined to be violent and murderous in the way the "heavenly doctor" treats her patients.

Yin Changying's good intentions, Yin Changying only listened to half of it.

He thought that his sister's idea was not unreasonable, so he instructed Zheng Gao: "Pass the meal!" ”

Yin Cheng raised her eyebrows: "Big brother, it's not okay to perfunctory me." ”

Don't think she doesn't know, this workaholic!

Even if this meal gives her face, but when he waits for the next meal, once he gets busy, he still won't remember, she can't stare at him every day!

Thinking of this, Yin Ji glanced at Zheng Gao.

Zheng Gao was afraid that the princess would say something like "I will leave these things to you in the future", so will he accept it or not?

If he didn't answer, he not only offended the princess, but also made the king feel that he was not loyal enough.

Then, he really didn't dare to shoulder the heavy responsibility of "letting the king eat and live normally" - his face was not as big as Yin Cheng, and the king would definitely not listen.

Therefore, he didn't say a word, and slipped away with the opportunity of passing the meal.

Yin Ji: "......"

I'm even more angry!

Seeing that her face was full of unhappiness, Yin Changying smiled and picked up the silk book: "Auntie, why do you make the vehicle so peculiar?" ”

When Yin Ji heard this, her mind also turned to business, and she leaned over and asked, "Which vehicle is peculiar?" ”

Yin Changying pointed to the "carriage" she had drawn.

Yin Cheng was designed according to the rail train of later generations, thinking that this idea may be a little too advanced, she explained: "Since it is a transport team formed by the state, it serves the military in wartime and the civilian population in leisure time." Then first of all, the speed must be fast. ”

Yin Changying also recognized this.

He once calculated that if all the roads in Yongzhou were paved and the tracks were paved, land transportation would even be faster than water transportation. From Lulong City to Gaoqi Pass, the army marched in a hurry, and it only took fifteen days.

This is already the limit of speed - after all, it takes human and animal power to pull a cart.

But Yin Ji's brain hole is much bigger than him, so without thinking, she took out a silk book: "Big brother, you see, if you make a simple power furnace at the front of the carriage, use the power of witches to pull the carriage forward." Then we can completely do not rely on manpower and animal power, and use the fastest speed to transport people and materials to various places. ”

Yin Changying realized the efficiency of doing this, and immediately asked, "How many days?" ”

"According to my estimates, it will take less than three days from Lulong City to Gaoqi Pass."

Speaking of this, Yin Ji had an indescribable and inexplicable emotion in her heart.

According to her observations, Zhaoguo's current administrative efficiency has actually reached the extreme of the feudal era. What restricts them is not the system, but the speed of information transmission.

According to her vision, in just a few years, traffic can leap forward, dozens of times faster than before......

There is no doubt that Zhao will become a real war machine!

And this is exactly what Yin Chang wins.

Therefore, he pointed to the small line of small characters marked by Yin Cheng and asked: "If this is the case, why is the carriage limited to twenty-four?" Each section can only carry one hundred and eighty people? ”

"If there are too many carriages, I'm afraid it won't turn around." Yin Cheng replied, "Of the twenty-four carriages, only four to eight are used to carry people, and the others are used to pile up goods. Too many carriages and too heavy goods are also easy to cause driving accidents. ”

Speaking of this, she did not forget to add: "This is just my preliminary estimate, and to really do it, it must go through repeated calculations and trial operation." ”

She didn't want to wait for the track to be laid and the car ready, only to have a major derailment accident and heavy casualties not long after driving.

Yin Changying thought for a moment before he said: "The construction of the track should be in order. ”

"It's nature."

Yin Cheng also knows very well that the track of national construction is a strategic need, and it is impossible to say that every place will be rolled out to you at the first time without distinction, and there must always be a sequential order.

The only priority to enjoy the track is strategic locations and densely populated cities.

For Akigu, there were undoubtedly three roads that needed to be built first.

Centered on Lulong City:

To the west to Yongcheng, this is the hometown of Zhaoguo, the source of soldiers;

To the south to Minjun, which is strategically important, you can go to the country of Zhu;

To the east to Gaoqi Pass, not to mention, the place where soldiers must fight, if you want to fight Zheng, Wei, and Liang, you have to take this road.

Moreover, the talents of the six eastern countries entered the Zhao country, and basically they all entered the customs by this road.

"After the eldest brother was crowned, I began to lead people to build tracks and roads from Yongcheng to Lulong City." Yin Cheng's thinking is very clear, "After the pilot of this road, find out the problems and improve them, so as to build the road to Gaoqi Pass." ”

Why put the southwest road last, one is because of the steep mountains and mountains, and the second is that it is difficult to build the road, and the other is ......

"The sleeping snake in the slope, what is the eldest brother going to deal with?"

"Hold it for now."

Yin Cheng was stunned for a moment, but quickly figured out that Yin Changying's thinking was right.

The mural in the slope road is obviously related to Feng Yi, the relationship is unknown, the snake does not know what the origin is, and the battle with it is small, if Feng Yi is recruited, the fun will be great.

"That being the case, the track to enter Minjun still needs to be carefully planned."

"Is there enough family?"

"Naturally, it's enough." Yin replied, "Just mix limestone, sandstone, and some minerals to make simple cement." ”

When she first learned about how Zhaoguo built a straight road in this era, she was simply stunned - in order to make the road smooth and not a single grass grows, they actually fried the soil!

Stir-fried soil! Unheard!

Even if there is a family construction, but the family is not a big witch after all, and their strength is limited, when can they get it? Of course, it is to sacrifice cement, a cheap and strong simple industrial raw material, and build all the roads in the country first!
