The three lieutenants had no intention of discussing with him, and the holy order was like a mountain, once he left Beijing, he would only have ten percent of the shares to be resolutely implemented, and there was no bargaining.

If you can bargain, then it's still called a holy order?

"General Tang, in fact, Your Majesty is more concerned about Gui and Ning than you, Your Majesty ordered you to return to Beijing, and there must be other instructions."

"Don't bargain, come with us."

“……”

Tang Yong couldn't discuss, so he could only listen.

……

With a thousand-mile ship and waterways all over most prefectures and counties, in just three days, he traveled north along the Yanjiang River from Yelang, changed to a carriage in Liangzhou, and after running for more than three hours, he returned to Chang'an.

He didn't even want to delay a moment of rest, and as soon as he returned to Chang'an, he went straight to the inner hall.

But I heard the imperial history say that Yuwen Shihong was in the country.

After going around and around, I finally saw Yuwen Shihong's figure in a remote corner of Guozijian.

"Huh? It's back, let's go, take you to see the latest armament. ”

When Tang Yong saw the catapult car, his face was as confused as Yang Shuang.

It wasn't until he saw the incendiary bombs that ejected out, turning the earth into scorched earth in a radius of three zhang a hundred zhang away, that Tang Yong was shocked because he realized the huge lethality of the new armament!

He also tried to extinguish the fire, but not only could it not be extinguished, but it was ignited with whatever he used to extinguish it!

Even if a stone touches the fire, it can be ignited by the fire.

Tang Yong was simply surprised.

"Your Majesty is mighty, and he can actually figure out such a terrifying heavenly artifact!"

Yuwen Shihong smiled without saying a word, and led him to the newly opened superintendent of Guozijian.

Inside the superintendent, there are young people everywhere, and in the courtyard of the superintendent, there are piles of wooden wheeled carts that you can't tell what they are used for.

Some have two wheels, some have two wheels, and some have five wheels.

"Master Zu, come here," Yuwen Shihong shouted to Zu Wenyuan, who was teaching mechanical principles in the superintendent:

"General Tang is here, show him how to use this wooden wheeled car."

Zu Wenyuan obediently walked out of the courtyard, pedaled on a tricycle, and rode around Tang Yong quickly for seven or eight laps.

Tang Yong's jaw dropped in shock.

"The ancients said that Shibei was impressed for three days, and the last general stayed in Yelang County for more than two months, and there was no progress."

"But there are earth-shaking changes in Beijing, which is simply shocking."

Yuwen Shihong smiled, and then sighed:

"It's a pity that the road collapsed, the car has long been off track, and the official road is of different widths and narrows, and the road surface is bumpy and uneven."

"On the rocky ground in the palace, this wooden wheeled car is still useful, but it can't show its ability on the official road."

Tang Yong nodded:

"Your Majesty, you should always take your time, it's just ...... If the official roads are all made of mountain stones, the large perimeter is vast, so ...... Fear of labor and loss of money. ”

"Hahaha," Zu Wenyuan said with a smile:

"Even if Your Majesty has such a plan, I will never agree with it."

"Look at this."

After that, Zu Wenyuan dragged two narrow iron bars with a concave middle from the corner.

The iron bar is about one zhang (3.3 meters) long and one foot (33.3 centimeters) wide, and the groove in the middle is about half a foot wide, and the depth of the groove is about half a foot.

"Iron is bad because it is easy to rust, so this iron bar is a copper-iron alloy, which is not afraid of rust, and second, the hardness is harder than copper than iron."

"It is more convenient and cost-effective to lay a track with the same width on the official road and make the car on the same track than laying the official road of the mountain and stone, General Tang, what do you think?"

"Even if the old-style horse-drawn carriages and donkey carts do not change the distance between the two wheels, the official road can still allow them to walk, and they can just walk without taking the tracks."

Tang Yong was once again amazed by Zu Wenyuan, who had not looked down on him at all.

After being amazed, he realized that the artifact that burned beyond a hundred zhang was probably also Zu Wenyuan's masterpiece.

Who cares about losing face now, Tang Yong is only full of admiration:

"Master Zu is really a great man! It was my clumsy eyes earlier! Please also have a lot of ancestors! Don't bother with short-sighted people like me! ”

"Huh?" Zu Wenyuan obviously didn't understand what he was saying, and directly ignored his apology, and then continued:

"Does the general want me to lay the same track to Yoro first? That is not possible, it is necessary to wait for the wooden wheeled car to go through several rounds of improvement, and confirm that the speed has reached the fastest and the force is the lightest, before it can be sold to the people, and the laying of the same track. ”

"It's impossible to lay the road to southern Xinjiang first because you and I know each other, so naturally we have to lay the surrounding areas of Chang'an first."

This time, Tang Yong didn't understand what he meant, and it took a while to react before Tang Yong came back to his senses.

It turned out that his sincere apology was regarded by him as a sycophant seeking personal gain?

Hey, forget it, Tang Yong's heart was full of crying and laughing:

"Although Master Zu misunderstood what I meant, forget it, I won't explain much."

"I also think so, if it is feasible around Chang'an, it is best to lay it on the north to narrow the distance between the north and the center at speed."

"In this way, there are many benefits."

"As for southern Xinjiang, there are many waterways in southern Xinjiang, and it is more convenient to take the waterway than by land, so southern Xinjiang ......"

"When it comes to southern Xinjiang, I also have other ideas, General Tang, you see the principle in this wooden wheeled car, do you understand?" Zu Wenyuan looked at Tang Yong with glowing eyes, hoping that he was a person who understood him.

As a result, Zu Wenyuan was disappointed, Tang Yong was a military general, where could he understand the precision structure of machinery.

Yuwen Shihong smiled and said for Zu Wenyuan:

"What Master Zu means is that the principle that the pedal can make the wooden wheel move forward quickly can also be used on the boat."

"With a little thought, you can do it by changing the details."

"Actually, the thousand-mile ship is not the ultimate goal of Master Zu, what he wanted to build at the beginning was a thousand-mile ship."

Tang Yong nodded excitedly, he was very confident in Zu Wenyuan, believing that he would definitely be able to create it.

And he felt that he couldn't stay here any longer, that it was time for him to figure out the catapult car.

A catapult car alone is enough for him to ponder for days, and may even keep him awake at night when he is excited.

After saying goodbye, Tang Yong trotted back to the Wei River, looking at the catapult car that was about to be used for him like a baby!

With this artifact, Yang Jian!

Wait for death!

And Yuwen Shihong didn't have time to get excited, he ordered the Guozi Supervisor to draw a map of the entire territory of the one hundred and thirty-one prefectures in the territory to him, and the main thing to paint was actually the official road and waterway.

The Zhuzhu Supervisor has always been very busy, and Tao Benyue, who was so busy that he went to serve as the supervisor of the Zhuzhu Prison at a young age, was lucky to jump from the mud legs to the Shi for only two years, and his temples turned white.

Under the circumstance that the commercial atmosphere is strong, the atmosphere of struggle for power is gone, but the atmosphere of profit-seeking is becoming more and more intense.

Yuwen Shihong roughly counted how many miles of official roads there were in the territory with a ruler.

I don't know if I don't count, but I don't know until I count -

There are only 350,000 miles of official roads in the territory?

Compared to modern times, even one percent is not enough.

The road is barely enough for the time being, but it is still too few.
