The canyon was bound by the rolling Yellow River water flowing southward. While walking, a fault suddenly appeared halfway through. The unexpected river water fell more than ten feet, wailing and hitting the riverbed, making a thunderous roar, arousing countless water columns and fire? Ran? ? ??????.

The river water turned into countless waves, slapped violently on the stone banks on both sides, but still could not break free from the constraints. The surging anger turned into fog and filled the canyon.

On the east bank, Yuwen Wen turned his back to the spectacular waterfall, and his right hand was holding Yuchi Chifan's shoulder. The couple stood shoulder to shoulder with a smile on their faces.

In front of the two, five steps away, several painters were drawing sketches for the emperor and empress. More than ten steps behind the painter, the concubine Yang Lihua and other concubines, led the prince and the princess, stood beside the wooden railing, enjoying the magnificent scenery of the Yellow River Waterfall.

The great reputation of the waterfall scared the young princes and princesses trembled, but they were afraid, but were shocked by the majestic scene in front of them, and they all watched them blindly.

It was the first time that Yang Lihua and several other concubines saw the majestic posture of the waterfall. She pulled her children and looked at the roaring waterfall in front of her, and only sighed at the amazing skill.

No matter how big or small, my attention was focused on the waterfall, and no abnormalities were found between the two people in front of me.

It was sunny today, and Yuwen Wen and Yuchi Chifan were posing on the bank of the Yellow River so that the painter could draw their figures. Now he has been standing for more than twenty minutes, and some sweat has oozing from his forehead.

Yuwen Wen resisted the urge to wipe his sweat and continued to smile. He could not invent the "camera", so he could only use this method to leave behind a clip of happy time with his family.

Because it was on the edge of the waterfall, the place was small and dangerous, Yuwen Wen only planned to "combined painting" with Yuchi Chifan, and the others were spared.

Not to mention the expressions of the little guys, they were obviously scared by this "crazy" Yellow River Waterfall. It would be nice to be able to keep watching the scenery from the side. If you get closer, you may not even stand steadily.

After a while, the sketch was completed. Yuwen Wen helped Yuchi Chifan walk back and found that the other party could not move. He seemed to be frightened and couldn't help but care: "Sanniang is scared?"

Yuchi Chifan smiled with a strong face: "Ah...I'm not afraid..."

"Oh...so, why not... let Si Niang come too, you two stand by your husband, and draw another one?"

Yuwen Wen said in a narrow voice. Seeing that Yuchi Chifan looked so anxious that he wanted to cry, he helped the other party continue walking forward.

Back in the safe area, Yuwen Wen looked at his children's fear and excitement, then looked at the sky, and then waved his hand: "Go and eat pastries!"

The little guys cheered, and under the guards' escort, walked up the newly paved stone steps, came to a relatively gentle platform on the half slope, walked into the carpeted camping site, and ate various small pastries under the cool umbrella.

Yuwen Wen held Yuchi Chifan, who was weak on his legs and entered the camp and sat under a cool umbrella. He looked at the Yellow River Waterfall in front of him, and ate pastries and iced drinks with his family, and felt extremely warm.

It's spring now, so you should have a spring outing.

Yang Ji led his army to "armed parade" on the grasslands in western Liaoning, and Shi Wansui led his troops to assist the Khan in the northern expedition. Both of these "spring outings" made Yuwen Wen yearn for it.

But as the king of a country, he was not good to wander outside all the time, so he could only take his family to walk around the Guanzhong area.

I’m tired of going to the surrounding areas of Chang’an. Yuwen Wen was unique this year and took his family to see the Yellow River Waterfall.

And all of them, together with their entourage, traveled on steamships.

So, riding a steamer itself is a novel experience. Although the ship is noisy, everyone is very excited.

Last fall, the steamer finally successfully tried the voyage. At the end of the year, the first steamer in the Guanzhong area was launched at the Pujin Shipyard. After the New Year, the number of steamer ships had exceeded 20.

Steamers are very important, so special matters are handled. It is of course necessary to manufacture ships so quickly.

In Guanzhong area, steam pumps have been popularized a few years ago, and there are more and more places to install heating in Chang'an City, so there are steam engine manufacturing workshops and steam steamers in Chang'an City, which are soon "copyed" by technicians in Chang'an.

The structure of the steamship is that with detailed drawings and data, the craftsmen at the Pujin Shipyard can easily draw pictures, quickly make the hull, install a new steam engine, and then the steamship can be launched into the water for trial sailing.

It is precisely for this reason that the manufacturing speed of steamships is so fast. Of course, the manufacturing of new steam engines is paid for patent fees per unit.

Yuwen Wen took his family and set off from Chang'an, arrived in Tongzhou by land, and then boarded a ferry-style steamer at the Yellow River Ferry and went upstream along the Yellow River.

Passing through Yumen (the southern end of the Yellow River Grand Canyon), enter the Yellow River Grand Canyon, and then berth more than ten miles downstream of Hukou Waterfall. By land, you can start an unforgettable spring outing.

In addition, Yu Wenwen personally conducted a trial voyage on the middle reaches of the Yellow River (the lower reaches of the Great Waterfall), and experienced the experience of different travel feelings.

Technology is productivity. When productivity increases, the imperial center's power deployment to the border areas can undergo qualitative changes. The Hetao area, which was originally very far away for the Central Plains, was no longer so far with the steamship Yellow River route.

If the impact of the Yellow River waterfall and the dangerous shoals in the upper reaches of the Chikou River on the shipping of the Yellow River can be overcome, then the steamship fleet heading north from the Pujin River section can transport hundreds of thousands or even millions of hu of grain to Jiuyuan, Suiyuan and other places in the Hetao region within a few months.

In this way, the cavalry corps in the Central Plains can be directly stationed on the Yinshan Mountains and can launch an attack on the grassland area in the south of the desert at any time.

Once the Hetao is completed, the offensive and defensive momentum of the grassland and the Central Plains will change instantly. Even if Qimin Khan, who returned to China to restore the throne, turned against him, the Zhou State will have enough strength to raise an army to question the other side.

It is precisely because of this layout that Yuwen Wen chose to send troops to help Qimin Khan return to China to clean up the mess and provoke internal conflicts between the East and West Turks. He originally planned to wait ten years before talking about the operation of the Hetao area.

It’s different now, because with the magic weapon of steamship, the power of the steamship can be used directly to support the operation of the Hetao area.

As he thought about it, Yuwen Wen smiled, making Yuchi Chifan, who was beside him feel irritated.

The steamship was magical, but she didn't want to sit because she was afraid that the boiler would explode and the ship would sink. As a result, she followed Yuwen Wen on the boat and was worried all the way;

She dared not approach the Yellow River Waterfall, for fear of falling into the abyss, but was held by Yuwen Wen and stood by the side for a long time (in fact, there is still a distance, which is safe enough), and her legs were so scared that they were weak.

Now, she was afraid that Yuwen Wen would come up with something else, so she took the initiative: "Uh... Erlang, then, the boat can't cross this waterfall, right?"

"Yes, of course I can't get through." Yuwen Wen was asked by the queen and became interested: "Didn't I say yesterday that the Yellow River shipping has existed since ancient times. In order to pass this big waterfall, the locals came up with the method of 'dry boating'."

"The boat came from upstream and berthed several miles upstream of the waterfall, where the water flow was not fast. Then, rely on manpower to drag the boat to the shore, drag the boat by manpower, walk around the waterfall through dry land, and go to more than ten miles downstream, and then go into the water at a stable place."

As Yuwen Wen spoke, his thoughts were led by Yuchi Chifan. He asked someone to use them to sketch and pointed to the black line on the river bank east of the waterfall above and said:

"This is the route of dry land sailing since ancient times, which is on the east bank of the Yellow River, and it is all done by boatmen."

"But there will be no need to pull boats in the future. Just as we go down to the Dizhu Mountains and Rivers section, we need to transport water and land to bypass the Dizhu danger. There will be railways in the waterfall area, and carriages will be used to transport cargo and personnel, and ships no longer need to travel on dry land."
