The city of black bones by the black bone river.

100,000 soldiers under the Black Bone City.

The Wugu River is a large tributary of the Yalu River, which can slow down the galloping cavalry. The Black Bone City, which was built on the side of the Wugu River, looks like a big dustpan, and through the low and flat bottom of the dustpan, the Black Bone City is on the mountain.

The flat road surface is warped.

Layers of stone walls rush to the face, the black bone city has both an inner city wall and an outer city wall, and there are two urn cities between the outer city and the inner city, each can accommodate thousands of soldiers.

Yu Wenshu looked at the mountain city from afar, his brows furrowed.

This city is located in the southeast of Liaodong traffic artery, southwest of Baiyan City, east of the Yalu River waterway, can directly access the upper reaches of the Yalu River of the Goguryeo hinterland of the Susheng Bone City, domestic city and other important places, the geographical location is very important, at the same time can also reach the Yalu River along the river, and then cross the river to Pyongyang, the capital of the Goguryeo king.

The Black Bone City is therefore large-scale, with a circumference of sixteen miles, which is much larger than the former royal capital and the domestic capital.

This city choked the way of Yuwenshu's soldiers and horses.

Wolf smoke during the day, beacon fire at night.

The Goguryeo people were heavily guarded, and it was impossible to pass by quietly.

There are many lookouts in the bones of Wucheng, like a pair of eyes that have been watching the surrounding area of the mountain city.

"General, the black bone mountain city is built of stone, the bottom is made of large stones, the stones have a sharp angle, intersect and bite into the heart of the wall, and then intersect with the wall stones on both sides of the city wall, the wall stone is also a wedge-shaped stone with a neat big head and small tail, and the tail end is intertwined with the filling stone in the wall, consolidated together, and formed a whole stone wall.

There is no need for mud joints when the city wall is built, and the stone blocks are inserted to form a tensile force, and the stone walls of each part are integrated with the whole mountain. The ridge is skillfully used, the cliff is the wall, relying on the mountain, the recess is the wall, and the circle is along the mountain, which is strong and abnormal. ”

"There are also many horse faces on the outside of the city wall, and there are large side angles on the outside of the bottom of the horse face, which not only strengthens the defensive ability, but also makes the stone wall stronger."

Yu Wenshu snorted, "You said so much, don't you just want to say that this black bone city is extremely strong, easy to defend and difficult to attack?" ”

"That's true."

The general replied, this black bone city is like a huge dustpan shape, in fact, it is a huge valley into it, the city wall is built on the top of the hillside peaks around the valley, and the valley mouth also built a city gate and urn city, guarding the traffic artery, it can be said that a man is a pass, ten thousand people can not be opened.

"Is there any other way to get around?" Yuwen asked.

"There must be a road, but it has to go around a long way, we have a lot of soldiers and horses, and carry a lot of baggage, there are many carriages and horses, if it is a detour, you can only take the big road, so it is estimated that it will take several times the road, and even if it is a detour, there will be many mountain cities on other roads."

Yu Wenshu's brows furrowed even tighter.

Such a city is not easy to attack.

It was huge, but it was dangerous on all sides, and even if he had three soldiers and 100,000 soldiers, he couldn't spread it. In particular, this city wall is very strong because of the mountain stone barrier, which is also built on the hillside, and many places directly borrow cliffs and cliffs, and it is difficult for general siege equipment to advance to the front of the city wall.

"It's a Great Wall."

Yu Wenshu scolded, this mountain city is indeed very similar to the Great Wall built in the north in the Central Plains, built between the mountains and mountains, which is very dangerous. The only difference is that the mountain fortress of Goguryeo is not a continuous long section, but a circle of mountain castles.

But the stakes are the same.

"How many defenders are there in the city of bones?"

Yuwen asked.

"According to reconnaissance, the city of Wugu City is sixteen miles around, and there are 10,000 people stationed in peacetime, and now I am in the Great Sui to conquer, and all the mountain cities have withdrawn their population and livestock into the city, so the population in Wugu City should be very large, and the number of soldiers and horses may increase, and we expect that there may be 20,000 to 30,000 people."

100,000 against 20,000 or 30,000, there is a complete advantage in numbers.

But as long as he takes into account the danger of this mountain city, Yu Wenshu is not optimistic, 100,000 soldiers attack the black bone city defended by 20,000 or 30,000 soldiers and horses, he does not have much confidence.

Especially now that they are four hundred miles away from the Liao River.

Along the way, Yuwenshu took the first army on the left, the second on the left, and the third army on the left, with a total of 100,000 horses, all the way south, and passed through the city, and the Goguryeo people did not dare to intercept it.

This way has been four hundred miles deep, and now it is stuck under this black bone city, but it is a bit of a dilemma.

The Black Bone City is not like other mountain cities, first of all, it is very large and strong, and there are plenty of soldiers and horses, and then this mountain city is not built on the top of a hillside, but a valley, which blocks their passage.

"What's going on in Liaodong City? Did you take it down? Yu Wenshu asked again.

An officer replied, "Previously, the 5th on the right, the 7th on the right, the 7th on the right, and the 73rd army on the right crossed the river, and was attacked by the defenders of Liaodong City, and our army fought bravely to cross, General Mai Tiezhu was killed in battle, and General Qian Shixiong was killed in battle, with nearly 20,000 soldiers. Although he fought against the water, he also annihilated 20,000 enemies, and killed under the city of Liaodong, but the Goguryeo people held on to the infant city, and also surrendered several times to get a chance to breathe, although after that, His Majesty no longer believed in the fraudulent surrender of Liaodong City, so that the production of flying towers, ladders, and rushing cars to attack the city, and the tunnels were advancing in all directions, day and night, but the Goguryeo people resisted very tenaciously, and now it has been more than 20 days and still cannot be pulled. ”

"What about casualties?" Yu Wenshu asked again.

"It is said that the Goguryeo defenders in Liaodong City suffered nearly 20,000 casualties, and our army suffered twice as many casualties."

At this time, Yuwenshu didn't know how to speak, the emperor personally commanded, 80,000 people besieged Liaodong City, but it was more than 20 days, but nearly half of them were killed and wounded, and Liaodong City was still not broken.

There was silence for a while.

Yu Wenshu said slowly, "Command the three armies, set up camp ten miles under the Black Bone City, rest and stand by." ”

The generals were puzzled.

"General, we are only a hundred miles away from the west bank of the Yalu River."

"I said wait."

"However, Your Majesty has ordered us to join up with the armies on the west bank of the Yalu River by the end of May and cross the river to attack Pyongyang."

"I said wait."

Yu Wenshu was still a cold Dao.

"What is the Admiral worried about?" One asked.

Yuwen Shu snorted coldly, "The right five, the left, the seventh, the right, the seventh, the third army, the three armies of 100,000 horses crossed the river to attack Liaodong City, it took nearly a month, and now 60,000 horses have been lost, but they still haven't captured Liaodong City, do you know what this means?" ”

This means that if the rear is unstable and Liaodong City cannot be captured, then the seven armies will not be able to continue to advance to the hinterland of Liaodong, let alone provide them with reliable support.

"However, His Majesty has urgently dispatched the six armies of the imperial camp to cross the river, and now the 200,000 troops of the imperial camp are already crossing the river and are assembling under the city of Liaodong. Liaodong City resisted stubbornly for many days, but it also suffered 40,000 casualties, and the city was also exhausted. ”

But Yu Wenshu didn't believe that Liaodong City had reached the point of exhaustion, he only saw that Liaodong City was still not down, and the three armies of the Great Sui under Liaodong City had actually broken two, even if the six armies of the imperial camp crossed the river, they might not be able to capture it for a while.

Maybe he can take it, but he Yu Wenshu doesn't want to risk storming the Black Bone City at this time.

When the good news of Liaodong City's breakthrough came, he would consider attacking the Black Bone City, otherwise, he would not attack the Black Bone City hard.
