In the long history, five years can be said to be a drop in the ocean, but for Xu Yang, the five years in Datang have given him the feeling of reliving a lifetime.

Mobile phones and computers can still be connected to the Internet, and every day you can see all kinds of news from later generations, when a modern person is stuck 1,400 years ago, what he can do is to flap his wings, although weak, but beyond the times, so that this fucking history will no longer be as fucked up as it was.

Xu Yang did it.

The Eastern Expeditionary Army returned from a great victory, and the celebration banquet was held in Chang'an for three consecutive days and three nights, and the people of the entire Tang Dynasty were celebrating the fall of such a powerful opponent at the feet of the Tang Dynasty. When Xu Yang saw him, this man who was described in the history books as a brave and fierce and burly man was taken into a prisoner car, looking scruffy and slightly white, and his appearance was quite decadent, which could not help but make people sigh.

On the peninsula, it has since become a three-legged trend, but due to the thunderous momentum of the Tang Dynasty's troops this time, it also made Baekje, Silla, and Wa very afraid, and they all avoided its edge and bowed to the Tang Dynasty.

It was not only these three small states who were vassals, but after learning that the most powerful of the Central Plains Empire had occupied the entire territory of Central Asia, many small states and barbarians in Central Europe sent envoys to express their willingness to submit to such a powerful empire.

Naturally, the great Li Er Majesty would not let go of this opportunity to make a long-distance friendship, and ordered Tang Jian, the counsellor of the household department, to arrive in those barbarian countries from the Silk Road with rich gifts, canonized handwritten letters, and festival flags symbolizing the authority of the Tang Dynasty to recognize the legitimacy of their regime.

The Crusade. There are many meritorious people. Li Ji was named the protector of the country, and Li Daozong was the king of the imperial county. There are also Wang Wendu, Xue Rengui and the like, Li Er rewarded them all lavishly, and even the merits of the soldiers of the Chengguan garrison team were all increased by two turns.

The front line has achieved a great victory, and the rear is naturally indispensable, and this time the crown prince Li Chengqian, who stayed in prison, was personally praised by Li Er.

Speaking of Li Chengqian, his coronation ceremony was unusually smooth, and everyone in the court had extremely high expectations for this flawless crown prince, and Li Gang, who was over his old age, even commented on him as "gentle and elegant." Familiar with etiquette, he can be the emperor of Ming. Let Li Erxin bloom and reward Li Gang with ten catties of gold and 100 horses of silk.

Xu Yang's efforts finally paid off in return, no lameness, no satisfaction, and no threat from the third brother, which is completely different from history, this time the throne in front of Li Chengqian is a bright and smooth road.

Li Chengqian naturally embarked on the path that Xu Yang had already arranged for him; As long as Li Eryi dies, he will inherit this empire immediately, so he is not in a hurry now, and there is no need to win over. There is no need to rebel, he just needs to wait quietly now.

The same is the prince. Li Tai has now become a scholar in the college, and is known as the four great examination gods of the college along with Long Aotian of the School of Medicine, Niu Shizan of the Department of Civil Engineering, and Luo Bingwang of the College of Letters; In every college exam, basically the four of them take the top four......

There are no more worries about the government, so Xu Yang is committed to developing people's livelihood and improving the public welfare of education.

In the first three years, Li Er called on the people of the whole country to plant potatoes and corn, and finally the output of these two crops reached a sensational level, and the eighteen granaries in Chang'an were all piled up, but even one-tenth of the potatoes and corn in the market were not enough, and the price of potatoes in the grain store had dropped to three cents a catty, but this could not be sold.

The people of the entire Tang Dynasty are a little confused, they can't believe that a few years ago they starved to death because they couldn't afford to drink rice porridge, and a few years later, the cellar and granary at home were full, but there was still a large pile of potatoes and corn left in the field and there was no place to store them, which made them feel a little like falling into a dream.

At this time, Xu Yang threw out the news of buying potatoes and corn, and for a while, the people of Baizhuang in the four counties around Chang'an sold their excess potatoes and corn to Xujiazhuang.

Just when everyone was curious about what to do with so many potatoes and corn purchased by Xujiazhuang, a chewy, smooth, and elastic food swept Chang'an, and it was from the hands of Guiguzi, which was famous: potato vermicelli. Along with potato vermicelli, there is also a food that has a golden exterior and a soft taste, like steamed buns, but there is a depression on the inside, which is called: corn nest head.

As soon as these two things came out, Chang'an was well known, and suddenly became a famous local delicacy in Chang'an, if you don't eat a meal made of these two foods, you are embarrassed to say that you have been to a nationalized metropolis.

Of course, no one noticed that Xujiazhuang made a lot of money by making zuò potato vermicelli and corn nests with the merchants of Chang'an.

The footprints of Chang'an's businessmen have now spread all over the north and south of the Tang Dynasty, north to the Silk Road, west to the Sichuan Basin, south to the Lingnan Mountain Road, and overseas Australia and other places, all of them have their figures, five years is enough for a small organization to grow into a behemoth: Qinglongfang Chamber of Commerce is such an organization, when Xu Yang founded the Tang Merchants Association, it was to organize the power of the merchants, and now, this force has become the point where it can influence the imperial court.

Li Er has promulgated and amended the "Commercial Tax Law" four times, but no matter how to revise and demand these merchants, businessmen are still eager to buy and sell, the Datang National Bank has popularized paper money, and now when buying things on the streets of Chang'an, it is rare to see someone directly taking out silver and copper coins, and some, all of them are paper money.

Qinglongfang has become a position for businessmen, and "Business Daily" was naturally born from here, and most of the things written are inspirational stories of getting rich, so that businessmen have a spiritual pillar.

In Datang, the status of the Xu family has reached an unprecedented level, almost to the point where everyone knows about it, and when it comes to the Xu family in Chang'an, everyone will involuntarily think of the Xu family in the Guigu.

"In no era has there ever been such a talented person who can be so versatile." This is Mr. Lu Deming's evaluation of Xu Yang, and his old man's words can be described as three points, because you can know by looking at the status of the Xu family.

In the court, since the victory of Goryeo, although Li Er did not reward Xu Yang, he promoted his official position of participating in political affairs from the second rank to the first rank, which is enough to show his appreciation.

Among the businessmen, Xu Yang can be said to be the leader, although many times he does not stand in front of the stage, but every big action made by the businessmen has his figure behind him.

Among the civil and military officials, this Guiguzi is even more left and right, not only has a very good personal relationship with Niu Jinda, Cheng Yanjin, Li Jing and other generals, but also with Fang Xuanling, Du Ruhui, and the eldest grandson Wuji are called uncles......

In the past five years, the railways of the Tang Dynasty have also developed in a blowout way, from the railway in Luoyang, north to Youzhou, south to Hangzhou, has been opened to traffic, and the slaves plundered from outside the territory have been sleepless day and night to finally complete the construction of the greatest railway of this era.

The gentlemen of the Mo family of Nanshan Academy who are proficient in mechanical art have also improved the steam engine to the fifth generation, not only burning less coal, but also the speed of the locomotive is faster, from Luoyang to Hangzhou, it originally took half a month to ride a horse, but now, as long as you take the train, you can arrive in just four days.

Since then, the domestic material mobilization of Datang has increased geometrically, and the grain that used to take half a month to be transferred by a manpower cart can now be reached by just a few days as long as it is sent to the train.

Just as Ma Zhou, the editor-in-chief of "Datang News", once wrote an article, "Since the railroad track was erected, the moat has changed into a thoroughfare, and the place where the north and south look at each other is already close to the end of the world, and the new era of my Datang has arrived......"
