Just as the Western fleet led by Han Xin conquered Anxi and the Middle East, the Eastern fleet led by Xiang Yu visited America.

Chen Xu also worked hard at the Xianyang Academy of Sciences to better rule the world in the future.

Quick communication and more convenient, efficient and safe transportation are issues that the Academy of Sciences urgently needs to solve.

In June 2488, the first simple hand-crank generator in the history of the Qin Dynasty was successful.

This simple electromagnetic device, which uses magnets as stator and copper wire winding as rotors, generates current manually by rotating the handle for the first time. Although this current does not have accurate detection of the equipment, and of course it cannot be calculated by the physical mechanics formulas learned before, there is a slight numbness under the touch. Judging by Chen Xu's experience of being electrocuted, there is roughly a few volts of weak electric power of at most ten volts. This current can instantly turn into the basin of the water.

Everyone in the Academy of Sciences was very interested in the special energy converted from the generator. Chen Xu took this opportunity to explain more power knowledge and future applications, and arranged people to find and make better magnets and develop better generators. At the same time, in order to convert electricity, invisible energy into visible energy, Chen Xu began to guide the development of light bulbs.

The current glass production is very mature. Although there is no experience in making vacuum bulbs, it has been successful after repeated trials. As for metals such as tungsten, it cannot be confirmed at present, but Edison, a great inventor, has existed in the Book of Heaven that can explain the world and everything. Chen Xu's first bulb still used carbonized bamboo silk as the luminous body. After nearly four months of research by the Eighth Institute, around the National Day, the bamboo silk bulb was driven by the hand-crank generator after countless improvements and innovations, and finally emitted the first unstable artificial light.

This is a great success and a great start.

At the end of 2488, when the bamboo silk lamp became stable, the first simplest single-cylinder steam engine in Daqin's history was also born.

This steam engine is just the simplest boiler and the simplest cylinder, but it can drive the piston arm to complete a complete set of continuous closed cyclic movements.

With this good start, the improvement and application of the steam engine is quickly put on the agenda.

The steampunk era of Daqin has already revealed its dawn.

In May 2489, the Institute of Power of the Royal Academy of Sciences achieved another technological breakthrough. The first controllable steam engine prototype was born and successfully drove the machine tool to rotate, and the running time was maintained for a full five hours.

In June, a modified steam engine was successfully driven on a modified carriage.

In July, Langya sent back the news, and the Qin Haishi fleet escorted Asia back to the West to restore the country. He heard that he brought back more than twenty ships of gold, silver and treasures and various Western precious items. The total value could not be calculated. At the same time, he also arrived at the envoys and commercial teams of hundreds of people from Western countries. The captured royal families and nobles of the Abnormal Empire were also among them. There were hundreds of young and beautiful Western ladies, each with white and tender figures, which made people drool when they saw it.

When the ships of gold, silver and wealth were unloaded in the harbors of Langya and Wuzhong, the entire southeastern counties were completely boiling to the point of being crazy.

According to the exciting publicity of the return merchants, sailors, boatmen, servants and others, the West instantly became a place full of rich fools. They never bargained for anything they bought, and they used money to buy anything.

The most popular ones are undoubtedly glass, porcelain, enamel, silk, and soap, matches, paper and pen, tea, red wine, etc., which are also extremely popular among the nobles. Each of these products is an incredible magical thing to the eyes of Westerners, and only gods can make it.

In addition, the perfume and sausage brought by Asia and a women's bicycle given by Chen Xu also became the objects of extreme envy of royal families in Western countries.

Of course, there are many ambitious people who hope to get the Qin Dynasty's steel crossbow weapons and even muskets.

This time, a large number of merchants and envoys came with him, all for different items such as the Qin Dynasty, and also brought a large amount of gold, silver and jewelry.

Faced with the Hanxin Merchant's process of making money like picking up money, almost all the merchants in the southeastern counties were excited and screaming. Countless people began to raise money to rent ships and recruit people to hoard goods, and soon they prepared to follow the Marine Fleet to make money to the West for the second time.

At the end of July, Han Xin led the Western Merchants and Missions back to Xianyang and reported to the First Emperor about his experience and detailed process of sending troops to the West.

At this time, Jiang Hu's military newspaper had not been sent back.

In view of the great success of the sea division fleet and the merits of capturing the Anxi King, Han Xin was awarded the title of Marquis of Anping County and the fief of thousands of households. He was also awarded the title of Major General, and all the other soldiers of the sea division fleet accompanying him were awarded the title of at least three levels.

The various businesses that came back with Han Xin were too fast and too fierce to make money, so they were very generous. The six businesses gave the First Emperor a total of nearly 50 million yuan of gold and silver goods, which immediately made the First Emperor happy. They waved their hands to the owners of the six businesses a bunch of lowest barons. After the news came out, it aroused the enthusiasm of merchants. A large number of merchants could not help but start inquiring about Western news, and gradually the business companies were preparing to go to the West to do business and make a fortune. There were even a large number of private people and hundreds of disciples, travel enthusiasts, and Fang Dao Warlocks all began to act and prepare to follow the world to see the outside world.

In March 2490, the steam engine made another breakthrough. The first twin-cylinder high-power steam-powered prototype was successfully developed and operated smoothly for more than 30 hours.

In August, the first experimental rail was laid at the experimental factory of the Academy of Sciences, with a length of three miles. Two months later, the first power head was running smoothly on the rails.

In March 2491, Chen Xu wrote to Emperor Shi, and officially began to lay the first commercial railway tracks in the Qin Dynasty. The distance was not long. It was built from the south bank of the Wei River in Xianyang Second Bridge to Weinan County. It was more than 150 miles long. The total cost of the project was 60 million yuan. Four stations, Xianyang South Station, Chang'an Station, Lixian Station and Weinan Station were designed along the way. In addition to the supporting locomotives, the total cost exceeded 80 million yuan.

The investment of this railway exceeded 500,000 yuan per mile, which is the most expensive road in human history. Although many officials in the court opposed it, the First Emperor did not hesitate to ask the Finance Department, the Shaofu and the Three Provinces and Six Ministry to strongly support it. The first railway in human history was successfully launched. In order to support Chen Xu in building the road, the Fan family and many civilian merchants donated generously, and the private donations reached more than 8 million yuan. Chen Xu himself also donated five million yuan. These donations greatly reduced the burden on the court and greatly accelerated the construction speed.

Two years later, in May 2493, the first railway in human history was successfully completed. On the day it was opened, there were crowds of people in Xianyang City and Chang'an and Weinan, and millions of people flocked to the south bank of the Wei River and along the railway tracks where the train passed, looking forward and waiting.

The first steam train in human history sounded its whistle, and it was opened with red and green, amid the cheers of the people, and dragged the passengers who were full of experience journeys, under the clear blue sky, thick white smoke, carrying hope and the future, drove out of Xianyang South Station with an unyielding momentum, and thundered along the railway tracks to the distance.
