After Yu Fei unified the north, he did not immediately choose to unify the south.

This war lasted a year and a half, and the total number of troops involved exceeded one million, affecting the entire Central Plains, and the little foundation accumulated in Guanzhong and Bashu was almost done.

And the Central Plains was basically destroyed after a big war, although it occupied the territory, but it could not be compensated, not to mention, before the first wave of grain harvest, it was still an extremely heavy burden.

In the face of millions of displaced people in the Central Plains, Yu Fei could only temporarily press his ambition, take out all the Longquan treasures of Xie Liang, and send Prime Minister Feng Dao to the Southern Tang Dynasty to discuss the purchase of grain.

Feng Dao did not live up to Yu Fei's expectations, and in the face of the difficulties of the ministers of the Southern Tang Dynasty, he not only maintained the majesty of the hall, but also used his eloquence to persuade many officials who were not very ambitious in the Southern Tang Dynasty to help, and successfully bought more than 6 million quintals of grain from the Southern Tang Dynasty at a price twice as high.

And Wu Yue, as Yu Fei's most loyal younger brother, also paid tribute of more than two million loads of grain, and transported it to Xiangyang by Han water.

With more than 8 million loads of grain and cattle and sheep from many small tribes in the grassland, Yu Fei was finally able to breathe a sigh of relief and re-recruit these millions of displaced people.

In the entire five years of Kaiji, Datang had a very difficult time, and Yu Fei also stayed in Luoyang for a whole year, carefully maintaining the situation in the Central Plains.

Time flies, since the defeat of the Liao State to unify the north, the entire Tang Dynasty has been working hard to develop production, and the Central Plains, which has been in turmoil for hundreds of years, has been restored to stability.

In the ninth year of Datang Tianji, with the cessation of war, the entire north was revitalized under Yu Fei's governance, and in just four years, there were more than 17 million newborn babies in the entire Tang Dynasty.

And in the southeast, the Southern Tang Dynasty will not sit still, and attacked the Southern Han Dynasty in the sixth year of Tianji, wanting to unify the south first, even if it can't win the world in the end, it can also be ruled by crossing the river with Yu Fei.

It's just that the final result is a bit of a fish, and after two years of fighting, although a lot of land is occupied, it also consumes the war potential of the Southern Tang Dynasty.

After the army returned to Jinling, the remnants of the Southern Han Dynasty rose again, and in less than half a year, the 30,000 troops left in the Southern Han Dynasty were driven out.

However, Liu Songzhi, the leader of the rebel army, who was a distant relative of the Liu family, did not want to follow the advice of his subordinates to reclaim the throne, but surrendered to Chang'an as the envoy of the Jinghai Navy, and sent an envoy to Chang'an with the population and land account books, asking for canonization and sending court officials.

And Yu Fei didn't do anything, he got a large area of land in the south, with a population of millions of households, and naturally behaved extremely generously, directly named Liu Songzhi as the king of Yue, led the Jing Navy Jiedu envoy, Zhendong General, and commanded the 30,000 Jing Navy.

And the Southern Tang Dynasty was naturally extremely angry, and he didn't get anything after a hard work, so that Chang'an, who had been watching the play, got such a big bargain, and the puppet emperor Li Yu vomited blood in Jinling, and died of illness in less than two months.

Yu Fei didn't know what the situation was, when he just wanted to launch a unified war, Nan Yi had accidents one after another, and even the enemy boss died directly, is this the legendary destiny?

In October of the ninth year of the opening of the Tang Dynasty, Li Jing, who had just taken over the throne, immediately surrendered to the throne, only called the lord of the country, and sent envoys to Chang'an to claim his ministers.

Yu Fei met with the envoy and directly made conditions, Li Jing could be crowned king, the family property would not move, and the whole family would move to Chang'an to live.

The envoy naturally didn't dare to call the shots, Yu Fei's condition was no longer surrender, but surrender, and the envoy could only return to Jinling with Yu Fei's conditions, Li Jing naturally wouldn't be willing, and made a farce to reclaim the emperor.

And Yu Fei also knew the answer from his performance of reclaiming the emperor.

In March of the tenth year of the opening of the Tang Dynasty, Yu Fei, with Guo Wei as the commander, led an army of 100,000 to the south to destroy the puppet Tang.

And Liu Songzhi, the envoy of the Jing Navy, also received Yu Fei's holy decree to use the 30,000 Jing Navy as a partial division to contain the puppet Tang Dynasty.

Wu Yue also sent 50,000 troops to threaten the rear of the Southern Tang Dynasty.

Faced with the situation of being besieged, Li Jing regretted it a little, asked the ministers, and wanted to surrender again.

This kind of capriciousness, naturally by the strong opposition of people of insight, the first envoy to Chang'an, directly descended can also get a good result, without losing the generation of wealth, now you are so capricious, but also re-called the emperor, and then what good results can be lowered?

After Li Jing listened to the advice of the ministers, he also gave up the idea of surrendering, and was ready to carry it to the end, with Zhou Yu's descendants and Zhou Ben in charge. 120,000 troops were dispatched, plus Huainan itself had 50,000 garrisons, against Guo Wei's 100,000 army.

In May of the tenth year of Kaiji, the Huainan War broke out, and the Tang army had experienced the unification of the north and defeated several times the elite of the Liao soldiers, led by famous generals such as Guo Wei, but they defeated Zhou Ben in just three months and besieged Shouzhou.

Most of the 170,000 soldiers and horses of the puppet Tang Dynasty were also scattered, and less than 30,000 people retreated with Zhou Ben to the fortified city of Hefei.

Guo Wei did not attack the city either, and used Hefei as a bait to defeat the Southern Tang troops who came to the rescue one by one

In April of the 11th year of Kaiji, Hefei was besieged for more than half a year, and after eating all the grain, he could only choose to surrender, so far Guo Wei occupied Huainan, built a warship in Chaohu Lake in Hefei on the spot, and dispatched sailors from Xiangyang to prepare to escort the army across the river to completely destroy the puppet Tang Dynasty.

In September of the 11th year of Kaiji, Guo Wei defeated the Southern Tang naval army at the Yangtze River, and in October, the army crossed the river and besieged Jinling.

In October, Li Jing surrendered Kaicheng, and all the ministers of the Southern Tang Dynasty were captured.

In November, Qian Yuanjun, the lord of Wuyue, surrendered the country to the Tang Dynasty and took his family and Wu Yue's ministers to Chang'an to meet the Son of Heaven. He was named the hereditary replacement of King Wu.

So far, the world is unified.

......

In the thirty-second year of the opening of the Tang Dynasty, under the governance of Yu Fei, the Tang Dynasty has reached its peak, and there is no opponent in the world, and its territory is far beyond that of the former Tang Dynasty, with Sakhalin Island and Dongying Islands in the east, Siberia in the north, the Caspian Sea in the west, and the Nanyang Islands in the south, all under the influence of the Tang Dynasty.

Yu Fei, who had been the emperor for more than 30 years, abdicated and handed over the throne to his twenty-seven-year-old eldest son Li Yan, while he took his wife to live in seclusion in southern Xinjiang.

In the second year of Yongning in the Tang Dynasty, Yu Fei broke through the realm of the Law Body and became a human immortal, and his longevity also increased to a thousand years.

In the fifth year of Yongning in the Tang Dynasty, with Yu Fei, a real immortal person, as a reference, the Twelve Mountains finally researched the Gu technique that could live forever.

Inspired by the Taoist Three Corpse Worms, three strange Gu worms were practiced, which were parasitic in the human heart, dantian and eyebrow heart ancestral orifices.

This method had just been researched, and after refining the three Gu worms, all the people involved in the Twelve Mountains died tragically for no reason in a year, and Yu Fei's million qi luck value was suddenly reduced by a small half.

Yu Fei knew that this was a natural earthquake and anger, and it was not that no one was allowed to live forever, but that there could not be such an easy immortality.

This method is too simple and against the sky, just three Gu worms can make people and Gu worms share longevity and prolong their lives for thousands of years.

If it weren't for the fact that he had the protection of atmospheric luck, I am afraid that it would not be much better than the people of the Twelve Mountains, even so, Yu Fei's more than one million luck disappeared in an instant, and this is the luck that blocked the catastrophe for Yu Fei.

In an unnamed valley in Miaojiang, outside a small bamboo building, Yu Fei hugged the empress and watched the sunset that was about to set in the distance.

"Shuiyun, I'm leaving."

"Hmm."

"Wait for me, I'll definitely come back to pick you up, I swear."

"Hmm."

did not ask Yu Fei to take her, nor did she ask Yu Fei to stay with her, she was always so understanding, she just silently supported Yu Fei behind her back, and never complained.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
