A week later, the Great Qin Xianyang City.

Under Ying Yu's personal guidance and arrangements, preparations for Da Qin's military parade are in full swing.

As the emperor, Ying Zheng was not idle either. He personally wrote invitations one after another and ordered them to be sent to all countries in the world, inviting them to send envoys to come to Daqin to observe the ceremony.

The preparations for the military parade went very smoothly, but the railway construction encountered difficulties.

Steam excavators have been officially put into use, the output of Daqin Steel has also been increased, and the speed of railway construction is gradually accelerating.

However, due to the accelerated progress of the railway, steam excavators and steel were no longer available in just one week.

Even if Daqin Processing Plant manufactures steam excavators non-stop, it will be difficult to meet the demand for steam excavators in Daqin for a while.

At present, the construction of the Daqin Railway has encountered two major problems.

One of the difficult problems is the construction of railways in Daqin, Jizhou and Wengshan areas.

In the Wengshan area of ​​Jizhou, the mountainous area is steep, the terrain is uneven, and the slope is large, making it very difficult to lay railways.

But if you want to connect the Taihang Mountains to the Jizhong Plain, the railway must pass through the Wengshan Mountain boundary. If it is detoured, it will consume a huge amount of manpower, material resources, financial resources, and time.

Going around is obviously a waste-of-gains approach.

The emergence of steam excavators solved the problem of laying railway tracks on the Wengshan boundary in Jizhou. However, there were too many curves for the steam train to make large turns. The terrain of the Wengshan boundary was complicated and the steam train was not allowed to turn around.

In this case, even if the rails are laid, if steam trains are unable to pass, then the rails will become decorations and serve no purpose.

Another problem is the railway from Daqin to Rome.

If the Qin Dynasty wanted to build a railway connecting to Rome, then the laying of the rails would have to pass through Longyuan and Zhuzhou.

The land of Longyuan is barren, and many places are desolate Gobi Desert. Although the terrain is relatively flat, the land is extremely soft and can be said to be filled with sand and gravel.

Zhuzhou has a dry climate and strong winds all year round, resulting in large areas of wasteland and desert in Zhuzhou, which also makes it difficult to build railways.

There is no rush to build the railway between Zhuzhou and Longyuan Dadi for the time being, because the railway track is still a long way from Longyuan Dadi and Zhuzhou. Maybe a solution will be figured out by then.

However, the railway construction in the Wengshan area of ​​Jizhou is already urgent. If it cannot be solved in time, it will affect the progress of the overall railway construction in Daqin.

When many ministers from the Academy of Sciences and the Academy of Engineering were at a loss what to do, Xiao He, Nei Shiteng and other ministers decided to ask Ying Yu for advice.

They believe that with Ying Yu's intelligence and talent, he will be able to solve the two most important problems in current railway construction.

The two of them hit it off immediately, so they set off towards the Prince's Mansion.

At this time, Ying Yu was organizing a team building barbecue in his back garden.

Seeing the two little girls running wildly all over the floor, Yu Ji touched her belly with envy:

"Your Highness, Princess Yu has been pregnant for several months and will soon give birth to an heir for Your Highness."

"Yes, sister Yu Ji is about to give birth. Sister Sophie, why are you not making any movement at all? You have to work harder."

Xiao Mei on the side said with a smile.

"Sister Xiao is right."

"Now our country, Great Qin, is advocating more children and more fertility in order to increase the population of Great Qin."

"As the issuer of political decrees and the Crown Prince of Qin, my husband must lead by example."

As soon as Xiao Mei finished speaking, Wang Ying, who was sorting out the ingredients, also smiled and said.

"Sisters, please stop teasing me!"

After hearing the words of several people, Sophie's pretty face instantly turned red.

But the eyes that fell on Ying Yu seemed to be filled with a hint of complaint, as if to say, look, they are teasing me, it's all because of your lack of effort.

In response, Ying Yu quickly avoided Sophie's sad eyes and quickly changed the subject.

"The weather has been nice these days, and there is nothing to do now anyway. How about I, my husband, take some ladies out for some fun?"

It was rare for Ying Yu to have free time, so he naturally wanted to spend more time with his two daughters, as well as his daughters' mother and aunts.

Hearing this, several people also showed joy on their faces, but before they could speak, they saw Qin Feng coming in a hurry.

"Your Highness, the Crown Prince, Xiao He, the Secretary of the Secretariat, Yao Jia, the Secretary of the Central Committee, Shi Teng of the Ministry of Household Affairs and several other lords are here to ask for an audience."

"They came at the right time." Ying Yu shook his head helplessly after hearing this.

"It seems that the ladies will have to prepare the barbecue for a few days by themselves."

Ying Yu spread his hands helplessly, and then brought Qin Feng to the living room.

"I have met His Highness the Crown Prince!"

"I have met His Highness the Crown Prince!"

"..."

Seeing Ying Yu approaching, Xiao He and others put down their teacups and quickly stood up to greet him.

"Okay, don't be polite. Several adults came together. Did they encounter some difficulties?"

Ying Yu waved his hand slightly, motioning for several people to sit down.
