The establishment of heroic monuments and martyrs' cemeteries, coupled with the perfect military merit system and preferential care system, established the high status of soldiers in the Tang Dynasty, and the status of soldiers became a symbol of honor and status. The high morale of the Don army was ensured.

After Xue Rengui and Gao Xianzhi were replenished, they commanded 500,000 Tang troops, reorganized the 300,000-strong army of the Jieri Kingdom and the 200,000-strong Tubo army, and swept across Southeast Asia and South Asia.

During the Spring Festival, Li Zhi and Cheng Chumo, the kings of Changsha, returned to Chang'an to report to Li Su on the construction of the navy.

So far, the Navy has 14 shipyards,

The Navy already has 45,000 troops, has established the Northern Fleet and the Southern Fleet, and has 8 first-class sail battleships and 252 other classes of sail battleships.

With the approval of Li Su, an ocean-going fleet was formed,

The ocean-going fleet consisted of three first-class sail battleships, as well as 118 other types of sail battleships, with a total of 28,000 soldiers, including 2,500 marines and 3,000 army soldiers, as well as 600 local officers.

July 12, Chang'an East Gate.

Today is the day when the first railway in Datang was opened to traffic.

Datang's first railway was an experimental railway from Chang'an to Weinan, with a total length of 67 kilometers.

In 1814, the world's first locomotive, Stephenson's steam locomotive locomotive came out, he invented this iron guy has a ton weight, there is a huge flywheel on the locomotive, this flywheel can use inertia to help the locomotive move, Stephenson named his invention "Brooke", this Brooke can drive a carriage with a total weight of about 30 tons, and in the next 10 years, he built a locomotive similar to Brooke.

Subsequently, after continuous improvement, a state-of-the-art steam locomotive was built, which he named "Voyage"

The locomotive of Datang chose the locomotive level of the early 20th century, and the technical level far exceeded that of the travel number.

Li Su took his wife and concubines, accompanied by Huang Qi, Minister of Science and Technology, to Chang'an Railway Station.

At this time, the wide and flat cement platform was already crowded with people, the main military and political ministers of Datang in Chang'an and the masses from all walks of life in Chang'an, there were tens of thousands of garrison representatives, and there were not so many people standing on the platform, and the rest were standing on the side of the railway.

A team of armed police soldiers maintained order on both sides of the railway, reminding people to pay attention to safe distance

The Political Department of the Tang Army also brought in its own band to help the fun.

People waited eagerly, looking at the railroad that was winding away, looking forward to the appearance of the train.

Suddenly, a rousing whistle was heard, and a locomotive sped towards him.

Behind the locomotive was a coal car, and 12 cars. The train approached, and the earth trembled slightly.

The audience was stunned, they couldn't believe their eyes, they didn't believe that the iron guy in front of them had so much strength.

The train approached slowly, and the crowd erupted in thunderous cheers.

The brass band played a rousing music, 12 gun salutes were fired at the same time, and people were celebrating the birth of the train in the Tang Dynasty.

The train slowly stopped in front of the platform, and from the carriage first came out of the beautiful railway uniform, the beautiful conductor in the uniform occupied the door of each carriage, and then, out of the carriage came out of the 500 armed police officers and soldiers, who were the first passengers.

After a brief ribbon-cutting ceremony, Li Su was the first to board the train, and Wei Zheng was the second to board it. Just like the ranking of later generations, people pay attention to the pedaling order of the Tang Dynasty's military and political figures, which marks the status of the Tang Dynasty's power figures.

In Datang, the top 10 are Li Su, Wei Zheng, Li Jing, Hou Junji, Huang Furui, Gao Jingming, Li Xiaogong, Li Dan, Du He and Huang Qi.

The top 10 leaders of Datang boarded the VIP coach compartment located in the 5th section.

Then, the eldest grandson Empress Dowager and Concubine Yang led the ladies to board the back carriages.

The VIP compartment of the bus is luxuriously decorated, and several beautiful girl waitresses walk back and forth, courteously entertaining the bigwigs

The train started and gradually accelerated, reaching a speed of 32 km/h.

Guests watched the scenery through the bright windows and exclaimed in admiration.

Li Su, Wei Zheng, Li Jing, Hou Junji, and Huang Furui sat together and listened to the report of the director of the railway bureau.

When the director of the railway introduced that the train could drive 20 carriages loaded with 40 tons, Wei Zheng said happily:

"Great, this train can carry enough cargo to carry 200 wagons, but it solves a big problem."

Gao Jingming asked, "Have you calculated the cost?" ”

When he heard that it cost less than a tenth of the cost of carriage transportation, he said with satisfaction, "This is a good thing." ”

When Li Jing heard that if the train carried all passengers, it could tow 22 carriages with 88 passengers, with a standard passenger capacity of 1,000 people, he calculated and said: "This can transport two battalions of troops at once, and it will be convenient for the army to move in the future." ”

Huang Furui said: "This railway construction should become the top priority of Datang's future construction, and it should be vigorously developed."

Li Su said: "Railway construction is very important for the military and the national economy, and the Railway Bureau should be upgraded to the Ministry of Railways." ”

The director of the railway bureau was suddenly promoted from the director level to the ministerial level, and he couldn't help but be overjoyed and hurriedly thanked him. He proposed that everyone name the first locomotive of Datang.

Huang Furui said: "This locomotive is mainly the credit of the emperor, and the minister suggested that it should be called Li Su."

Hou Junji said: "The minister agrees. ”

Everyone agreed.

Li Su said: "This locomotive is not my own credit, it embodies how many scientific and technological workers and the efforts of the majority of workers, I think it is called Datang, symbolizing the steady progress of Datang along the right track."

Everyone thought he had a point, and finally named the locomotive "Datang"

After this trial operation, the superiority of the train has been fully reflected, it is fast, stable, comfortable, safe and reliable, and Datang's railway transportation business has officially started from this day.

The construction of railways involved the construction of railways, the design of bridges, the manufacture of locomotives and rolling stock, all of which were compiled by Empress Qibi Wuyun, who simply served as a consultant in the construction of railways.

In this way, trains have developed rapidly in various parts of Datang, which has greatly promoted the development of the national economy.

On the day of the railway's trial operation, Khalid, the great general of the Arab Empire, who was mixed with the crowd of visitors, looked at the huge train, its amazing speed and carrying capacity, and fell into deep thought.

At an Arab trading house, Khalid met Harold.
