Thang Long.

Yang Feng slowly flew in the sky, looking down with a majestic gaze.

And on the city streets below, countless Annan soldiers and civilians knelt on the ground and kowtowed to welcome the arrival of the gods.

His journey into Thang Long was simple.

Although Chen Shuming didn't come out to raise his arms because he wanted to play loyalty, this little thing could be solved by Li Jiyu, and then all that was left was for the Nanding defenders and reinforcements to partner up, hold high the banner of Fengtian to punish the guilt, and turn around and kill Xiang Shenglong. The Song army left part to take over Nanding, and the remaining 13,000 troops also followed Li Jiyu to march into Thang Long to preach for crimes, and when they arrived at Thang Long, Chen Yuzong still wanted to resist, although there was no army in the city, but there was still no shortage of young people, and he recruited young men to defend the city as quickly as possible. However, as soon as the cannon of the Song army rang out, his patchwork soldiers scattered from the city wall, and when Yang Feng took to the air, the city officials immediately opened the city gate, and then the civil and military officials ran out to meet Wang Shi, as for the unlucky Chen Yuzong......

Suicide in fear of sin!

What else could he do?

It is said that he hung the southeast branch, it doesn't matter whether he hung it himself or someone else, in short, he is already dead, and there is no need for Chen Shuming to take the charge of killing his younger brother.

"Disciple greets the Immortal Master!"

Chen Shuming led the civil and military officials to bow in front of the imperial city.

"Chen Shuming, the king of Chen's annam, greets the angels!"

Then he changed his name.

The former was his greeting of the gods, and the latter was his greeting of the emperor's envoy as a vassal king, but both were the same person, and at this moment he was still the king of Annam, who was analogous to Goryeo, which was inherited from the time of Song Hyojong. Before that, although the ruler of Annam had a large number of prominent titles on his head, he could actually only be regarded as a local official of the Song Dynasty, Jinghai Jiedu Envoy, even if he was added to the king of Jiaozhi County, he was still a Jiedu envoy, and it was Song Xiaozong who finally named him the king of Annam in order to fight for Annam with the Jin State, which fundamentally changed the relationship between Song and Annam, who changed from a magistrate to a vassal king with a tributary relationship.

This was also the beginning of the kingdom of Annam.

Before that, no matter how they divided one side or even invaded the Northern Song Dynasty, in essence, they were all local officials of the Song Dynasty, and they were just a continuation of the Five Dynasties and Ten Kingdoms.

But Song Xiaozong's title of King of Annan made them complete a qualitative change, which Yang Feng was not ready to change for the time being, in fact, Ming Yuzhen, Chen Youliang, Zhu Yuanzhang, and Zhang Shicheng were also similar at this time, they were all vassal kings, and their jurisdictions were all vassal states, and they did not belong to the ruling area of His Majesty the Emperor of the Great Song Dynasty. As for the Great Song Emperor, or his apprentice Zhao Lin'er, the only direct ruling area at this moment was to restore the Song Dynasty's Xuanfu Zhi envoy system, and appointed to Fang Guozhen, Chen Youding, He Zhen, and other people's jurisdictions, they belonged to the direct jurisdiction of the Great Song Emperor......

Of course, only nominal.

The Great Song Dynasty didn't even have a court, and His Majesty the Emperor, who was a bare-bones commander, was still studying in the White Jade Palace.

In this case, there will be no more Annan.

Anyway, this vassal king is canonized by the emperor, and the emperor also has the right to take it back, no matter who becomes the emperor in the end, he will inherit these territories directly under the emperor of the Great Song Dynasty, and the land seized by these vassal kings in the course of the Northern Expedition is not within the scope of their vassal state, and their vassal state is limited to their original control area, so that the land they laid down will also belong to the emperor to inherit.

Then the final elected emperor will gain an overwhelming advantage over the vassal state.

After all, the strength of those three guys is basically the same, although Zhu Yuanzhang is the strongest, he may not be too strong than Chen Youliang, even if Zhang Shicheng really wants to work hard, he will not lose to the other two, when one of them obtains the territory and population of the entire North China Guanzhong, Northwest Fujian, Guangdong, Yunnan and Guizhou, it will definitely crush the strength of the other two, and there is also a righteous body, and there is a god to support him.

And then all that's left is just a big political return.

Not only Annam, but also Goryeo will be dealt with in a similar way, first of all, let them think that they are the Great Song Domain, and like Ming Yuzhen, they will not participate in the competition for the Mandate of Heaven but wait for the Mandate of Heaven to return, so when the new emperor orders that the great governments of the feudal domains will be returned, as long as Ming Yuzhen receives the decree, these people have no reason to refuse. Refusal is to resist the decree, the emperor has the right to send troops to arrest and punish the crime, they dare to resist the mandate of heaven by force, they dare to resist the mandate of heaven is to defy the power of heaven, and then the immortal master will take action, such as flying directly to the Imperial City of Thang Long to take the king of Annam out and fly back to the capital to be punished. If the people of Annam still dare to resist, then whoever gives them the king of Annam will be taken by the immortal master to cut off their heads, it is estimated that it is enough to cut one, this way can also avoid the loss of population in Annam, Annam is still a Han in the final analysis, although there is a modern Beijing people, but they are really Han people.

During the Three Kingdoms, the population of Jiaozhi County was more than that of Nanhai County, where Guangzhou was located!

Even the Tang Dynasty was half of the latter.

The entire Annan of the Tang Dynasty had nearly 60,000 households, which was less than Yangzhou, the most prosperous in the world at that time, and the latter was more than 70,000 households, according to the proportion of Yangzhou's household registration, then the population of Annan was more than 400,000, and these people multiplied in a relatively stable environment for more than 400 years, and they had to add a large number of people who fled to Annan for refuge at the end of the Song Dynasty, so how many people did they have in this era? There may be fewer Han Chinese in the south, but the Red River valley can almost be said to be entirely Han Chinese.

So what Yang Feng wants is to annex them.

"The Annan world is the land of China, and the world is the people of China, although one side is divided, but also the ministers who defend the land, this immortal generation of the world, choose the lord of the mandate of heaven to guard China, you need to guard the frontier to wait for the lord of the mandate of heaven, the immortal commander of the army needs to go through the west of the land of Annan to ask for the Tatars, all the military supplies are handed over to you, and there is no mistake in being cautious."

Yang Feng said in mid-air.

"Obey the order!"

Chen Shuming hurriedly said.

Yang Feng nodded with satisfaction, then landed, and then helped the newly baked king of Annam, and walked into the imperial city in front of him under his humble guidance, which has been preserved until modern times.

Behind them were more than 100,000 soldiers and civilians who kept prostrating, and in front of them, three thousand Iron Men stood with their backs to the city wall, all in plate armor and holding two-handed giant swords, forming a formidable steel wall, and those soldiers with flintlock muskets had also climbed the city wall. These people are really responsible for the battle, and the Iron Man Army is only responsible for pretending, and in case of heavy rain and flintlock pistols are not good, after all, Yang Feng has not equipped his subordinates with a starting gun, and it is best to have such a spare one in the rainy environment in the southwest. The only defect is that it is afraid of heat, and it is not comfortable for the plate armor to let the scorching sun shine, but it is winter now, and about 20 degrees is good weather, even if it enters Yunnan to fight in the future, it doesn't matter.

Yunnan is a plateau, so you don't have to worry about the subtropical sunshine.

In this way, Yang Feng completed the conquest of Annan.

Of course, it's not that simple.

He only conquered the Red River Valley, and at this time, it would take some time for Annan to go south from the modern border south to the south of Hue, after all, it was too sudden, and those local officials and other clans who did not know the situation would inevitably have ideas, saying that Annam was already quite chaotic.

Only half a month later, Du Ziping, the general of Annam, who was originally in Huazhou, that is, Hue, raised troops.

Of course, he is ready to come back to crusade against Chen Shuming, who murdered the monarch and rebelled.

But it's a pity that as soon as the fleet he led came out of Huazhou, he encountered Fang Guoying, who escorted Li Jiyu south to receive his army, and the latter's hundreds of large warships were all equipped with Yang Feng's hand-rubbed steel cannons in Shilu Iron Mine. Fang Guoying's army, from plate armor to cannons to flintlock pistols, was all hand-rubbed by him in Shilu Iron Mine, that is, the amount of gunpowder was limited, so each cannon could not hit a few rounds, and it was not heavy, the largest was only twelve pounds, and most of them were six pounds or even three pounds, but it was enough to scare people

A salvo of nearly two thousand guns of various calibers shook the sea.

After just this round of volleys, Du Ziping's generals did not hesitate to tie up their commander, and then ignored his angry cursing and gave him as a gift to Li Jiyu, who also unceremoniously cut down this short-eyed guy, and then went south together with Du Ziping's troops, still relying on Fang Guoying's naval guns to sweep the coast of Zhancheng, and blocked it until the capital of Zhancheng.

It's also the modern Thu Nhon.

Although Li Jiyu was eager to deal with their main enemy once and for all, such as landing and then burning the city with the same fire as Li Rizun did back then, it was a pity that the A'a people reacted much faster than him.

The latter surrendered without hesitation.

Anyway, Champa was also a vassal state of the Great Song Dynasty back then, and it was also one of the most friendly vassal states with the Great Song Dynasty, after all, they were the main transit point of the Nanyang trade, and the pirates who attacked the Great Song Dynasty liked to call themselves Champs after they were caught, and then received leniency from the Great Song Dynasty. Now the king of the Great Song Dynasty came to the door, and he came to sweep away the Tartars who also had a deep blood feud with the Champa city, of course a smart person like A'a knew what to do, but the Mongols and Annam jointly beat them back then, and even the Champa province was set up, and sent sailors to cross the sea to beat them.

Now Wang Shi has come to avenge them.

He immediately sent someone to send tribute, and at the same time accepted the canonization of the king of Champa and became a vassal king similar to Chen Shuming, originally they also had the canonization of the Great Song Dynasty, but now it is just a reconfirmation, and then he patted his chest and promised that he would get along with Chen Shuming, at least until Wang Shi swept away the Tartars, he would not have a war with Chen Shuming to drag Wang Shi back, and he also agreed to Fang Guoying's request for him to provide some food as support......

He didn't dare not agree!

More than 400 warships blocked outside the gate of his national capital, although these warships are certainly not the same as sail battleships, and even frigate-level armament cannot be reached, but those largest warships are equipped with more than a dozen nine-pounder guns without pressure, all the warships add up to nearly 2,000 guns, and the scene of so many cannon salvos makes his legs weak!

Isn't it just rice?

There is no shortage of rice in this part of the city.

In this way, Yang Feng completed the conquest of Champa and ruled the war between Champa and Annam, the two sides ceased war so that the latter could draw manpower to transport materials for the Song Dynasty, this transportation line is still not so simple, water transportation is not worth mentioning, Annan is not short of ships, Zhu Laosi Ping'an Nanhou alone received nearly 10,000 ships, not to mention that after leaving some of the actual military supplies of 15,000 people, even if it is expanded tenfold to Annam's inland water transport capacity can also be guaranteed.

Land transportation from Butou to Kunming requires a lot of manpower.

It's a 500-mile mountain road.

However, Li Jiyu came up with a good solution for him.

Elephant.

Elephants are used for transport.

First of all, although this road is a mountain road, it can only be said to be a mountain road, which is different from the real mountain road, and has been walked for thousands of years, and the materials can be transported by livestock, but their biggest problem is that there are no horses, and there are only a few hundred cavalry in the whole Annam, but they have elephants, not only they have, but also the Cham people, both countries have a large number of war elephants, and the people also have a large number of elephants, which can be transported by these domesticated elephants, and they do not need to be specially fed, and it is almost enough to eat wild plantain along the way.

It didn't take much to make a pack of 500 elephants catch up with nearly 10,000 porters.

In that case, no problem.

Immediately afterwards, Yang Feng gave an order to the Ataka to requisition 300 elephants, and the latter was somewhat reluctant, after all, they also relied on elephants to fight, but in the end they still did not dare to resist, but on the grounds that they needed to face the threat of the Zhenla people, they asked Yang Feng for some small cannons and flintlock pistols, which Yang Feng also gave to the Annan people.

Anyway, with their current ability, it is impossible to imitate the flintlock pistol, at most they will forge some small bronze cannons themselves, and they will have forged them themselves.

In this way, by the spring of 1364, everything was ready for Yang Feng.

Even the fortress of Butou was established in advance by Chen Shuming, which was originally not in the territory of Annam, and the border between Annan and Yunnan is Hekou Old Street, as for Butou at this time, it is called Lihua Old Market Station, which belongs to Mengzi County in Yunnan, and is actually the town of Manchu on the bank of the Red River in the south of modern Honghe Prefecture. This section is called the Lihua River, the upstream is called the Yuanjiang River and even the road level administrative area of the Yuanjiang Road, and the following estuary is not called the Red River but the Tao River, that is to say, this transportation line first takes the big boat along the mouth of the Taojiang River Water Canal, and then turns the small boat to transport it upstream to the head. Then start the land route to the north to Mengzi at the beginning of the step, at this time there belongs to the Lin'an Road under Yunnan Province, the road is governed in Tonghai, there is a perfect transportation system, whether it is to the north from Amisui Prefecture, that is, to open far north, along the Nanpan River to Yiliang to Kunming, or to the west to build water through the sea to Dianchi Lake on casual.

In March of that year, Yang Feng boarded the ship in Thang Long and led an army of 15,000 to embark on a thousand-mile expedition to Yunnan.
