Before attacking Liaodong City, the Tang army was even prepared for heavy casualties and at least a month's time.

After all, such a fortified city with a large number of defenders is impossible to do without paying a sufficient price according to past experience.

But no one expected that Wang Xiao would be superb, and he would take down Liaodong City in one day. The huge victory made the Tang army a little unsure of where to fight.

Li Er convened everyone to discuss the next goal, and Wang Xiao put forward a different proposal.

"The Goguryeo people fortified the walls and cleared the wilderness, and also built a long series of fortified cities to consume the Tang army. If such a city is fought, it will not be able to finish until next year. Why don't you just cross the sea by boat and go directly to Lelang County? ”

The core of Lelang County is Pyongyang, and the Mizi Joseon is here in the Miseong, and when the Manchurian Korea was defended, it also went from the Central Plains.

During the time of Emperor Wu of the Han Dynasty, he broke through the city of Wang Wei and built four counties, which was the land of the Han Dynasty.

Among them, Lelang County is the core of the four counties, and the core of Lelang County is Chosun County, and the county is Pyongyang City.

To say the last sentence, since ancient times, there is absolutely no problem.

"Crossing the sea by boat and hitting the capital of the Goguryeo people?" At this time, people did not have the concept of amphibious warfare, and they could not understand it for a while.

"Conquer the royal capital of the Goguryeo people and capture their king. The rest of the small towns and small pools, can they still turn the sky upside down? ”

Wang Xiao's words moved Li Er, but there are still practical problems that need to be solved.

"There are too few ships, and they can only transport up to thirty or forty thousand horses at a time."

"The sea conditions are unknown, and if there is a storm, it will be all over."

"Goguryeo has allies Baekje and Fuso, and they both have sailors, and Goguryeo's own sailors are not weak."

"If it can't be defeated, how can the logistics be solved?"

There are a lot of questions, and all of them are very important. The slightest occurrence could lead to catastrophic consequences.

For these questions, Wang Xiao answered them one by one.

"Sea conditions or something, Datang has a lot of fleets that do business with Goguryeo, just ask them to be guides."

"Thirty or forty thousand horses is a lot, and it is enough to siege the city without people, only soldiers."

"Logistics or something, the whole army carries a month's worth of military rations. When the royal capital of the Goguryeo people is conquered, there will definitely be no shortage of food inside. ”

"As for the storm, it's autumn harvest now. Make preliminary preparations, collect ships, transform warships, or something, let alone two months. Basically, you won't encounter it when you set off. If you really meet it, it is unlucky, fate. ”

"Goguryeo's sailors and allies will be destroyed directly when they see it."

The eldest grandson Wuji pouted when he heard this, "Where is it so easy to destroy." ”

Wang Xiao didn't argue with him, but looked at Li Er.

Li Er coughed and said to the eldest grandson Wuji, "Have you forgotten that when your family made kerosene, there was another kind of oil?" ”

"Kerose?"

Wang Xiao contributed a ballista early on, which could fire a canister filled with fire oil.

During naval battles, this kind of oil canister smashed on a wooden ship, that is a super killer.

"This thing is on the Great Qin side, and it's called Greek Fire. Our oil is more efficient. ”

Daqin is the name given to the Roman Empire by the ancients after the opening of the Silk Road. It is also called Hercynian people, which means the west side of the sea.

Ban Chao of the Han Dynasty once sent Gan Ying as an envoy to Daqin, and he even went to the Persian Gulf. It was the world of BC.

Almost all of the Datang's sailors were equipped with ballistae that were light in weight and had a long range. If a naval battle really breaks out, it will certainly teach the enemy an extremely profound lesson.

The kind of lesson that you can't forget for thousands of years.

The unprecedented sea-crossing attack made Li Er very undecided.

But the thought of striking over land would break through a long list of cities and crush hundreds of thousands of defenders. He had the motivation to make up his mind.

It's really hard to get on the road.

There are so many cities that you can't leave a single one behind, and you have to conquer them all. Otherwise, if one is missed, the longer and longer logistics supply line will be attacked and cut off. The consequences are self-evident.

Even if Wang Xiao can show his might every time he besieges the city, the losses of ordinary Tang troops will still not be small.

And calculating the time on the road, if you really hit Lelang County from the land, it is estimated that it will have to start spring next year.

Li Shimin is also a person who dares to take risks, which can be seen from the fact that when he fought a decisive battle with Dou Jiande, he dared to personally lead the troops to charge into battle.

"Then take the sea route."

After making up his mind, the Tang army moved quickly.

Sea ships from all over the country were assembled, and sergeants who were not seasick began to be selected in the army.

Mobilize personnel and ships, stock up on various supplies. Three months later, before the snow fell in the north, 33,000 Tang troops boarded the fleet, escorted by more than 100 naval warships, and headed in the direction of Lelang County.

In fact, the Goguryeo people knew about the dynamics of the Tang army, and they had already made preparations.

After all, there are so many ship movements, and no matter what, the spies of the Goguryeo people cannot be hidden.

The Goguryeo people did not panic, but felt happy.

Before the battle of Liaodong City, it brought a huge shock to the Goguryeo people. They even suspected that there was no chance of winning the Tang Dynasty in land warfare.

And now the Tang army actually took the initiative to give up the advantage on land and switch to the waterway. This made the Goguryeo people feel that the opportunity had come.

They first mobilized their sailors to gather, and then appealed to their allies Baekje and Fusang for help.

Out of fear of the Tang Dynasty, both Baekje and Fusang sent their own sailors to support.

There are more than 1,000 large and small ships of the Three Kingdoms Navy Division, and it is said that there are more than 100 warships of the Tang Army's Navy Division.

Even if the Tang army is a big ship, the ratio of ten to one means that it will win.

Whether it is the Goguryeo people, the Baekje people, or the Fusang people, they all think that this is stable.

Before the winter snow fell, Datang's fleet finally came to the mouth of the Datong River.

At this time, more than 1,000 ships of the Triple Alliance had gathered here. The stretch is almost all over the water.

The science and technology of the Sui and Tang dynasties, not to mention in East Asia, was the top in the world.

Datang's shipbuilding technology is very superb, the walls are high and strong, and the design is excellent. And all of them are big ships.

The ships of the Triple Alliance, not to mention the technology, are mostly small boats.

There was no nonsense on both sides, and soon the sails were puffed up and the battle began.

The ships of the naval divisions of the Tang Army were equipped with ballistas, which not only had a long range, but also had a high accuracy.

What's worse is that the ballista fired not stone bullets, but clay pots filled with oil.

The clay pot was sealed and a fire rope was lit on the outside. When thrown into the sky and landed on a wooden ship, the clay pot will be shattered. The oil inside will spill out. At the same time, it will be ignited by the fire rope.

In recent years, the ships are all wooden, and Datang's ships have been fireproofed, and it is estimated that they can't withstand this kind of burning. And the ship of the Three Kingdoms Alliance didn't have this thing at all, and if you throw a can, it will burn immediately.

When the flotilla of the Three Kingdoms Alliance gritted its teeth and approached with huge losses, the Tang army began to release rockets again.

Although the rocket is not fueled, it is enough to deal with these small wooden ships that have not been fireproofed.

After gritting their teeth again and carrying huge losses, the Three Kingdoms Alliance sadly found that the walls of the ships of the Tang Navy Division were very high, and they couldn't reach them even if they wanted to.

And the few big ships that can reach are set on fire as the main target early, and after being smashed I don't know how many oil jars, they all become burning torches on the sea.

The fire in the sky was reflected and the smoke of gunpowder obscured the sky.

Countless people from the Three Kingdoms Coalition slowly sank to the bottom with the ship. Or jump out of the boat screaming and jumping into the sea in the light of fire.

The entire Datong River Estuary has turned into a blood-fire hell, and even the sea water has been dyed red.

The confident Triple Alliance collapsed directly, and all the ships that could still move turned their heads and fled frantically towards the shore.

The so-called siege of a thousand ships is a joke under the crushing of advanced technology.

A group of broken ships not much bigger than fishing boats, and they still want to fight against the giant ships of Datang? Look down on people.

After the sailors cleared the trouble, the fleet full of Tang soldiers drove over slowly.

There are no landing craft and no docks. So it's impossible to get to the shore.

A lot of small boats were put down on the ship, and waves of Tang troops were transferred ashore.

There were originally tens of thousands of Goguryeo soldiers stationed on the shore, but when they saw the tragic scene of the destruction of the sailors, they were rushed by the officers and soldiers of the sailors who rushed directly to the beach, and all the hula ran away.

This made many of the landing countermeasures prepared by the officers and men of the Tang Army useless.

The Tang army, which had come ashore, began to quickly build an improvised wharf.

There is no doubt that this is also the technology provided by Wang Xiao. It is to make a long plank road in advance, and then load it separately and transport it on the ship.

After landing, the pieces were put together, but there was already a plank road deep into the sea after half a day's work.

One ship after another approached, and a large number of Tang troops quickly went ashore along the plank road with supplies.

By the time the Goguryeo people received the news the next day and mobilized their troops and horses, there were already more than 10,000 Tang troops ashore.

The Goguryeo army, which had been hastily concentrated, was quickly routed by the Tang army.

The Tang army did not pursue, firmly guarding the shore, waiting for the follow-up personnel to disembark.

Three days later, 33,000 Tang troops set foot on the banks of the Datong River with supplies, and this time the leading general was Li Shichang.

Originally, Li Shimin wanted to come in person, but all the civil ministers and military generals persuaded him and didn't dare to let him get on the boat.

In the end, Li Er, who was helpless, could only let Li Shiyun lead the troops.

The landed Tang army quickly moved and arrived at the city of Lelang County after another two days.

This is a city that is stronger than Liaodong City and has a taller wall.

The defenders of the city are said to have numbered more than 40,000 men, and more men have been mobilized to go to the city.

In the face of such a strong city, Li Shiyun also scratched his head a little.

He remembered Li Shimin's explanation before leaving, saying that he asked Wang Xiao when he was attacking the city.

With doubts in his heart, Li Shiyun found Wang Xiao and asked him how to attack the city.

Wang Xiao took him to the material camp, pointed to dozens of large boxes that were strictly sealed and placed in isolation, and said, "If you want to break the city, these are enough." ”

Li Shiyun was puzzled: "What is this?" ”

"Black powder."
