After contacting Wei Chigong, he mobilized craftsmen and soldiers to build iron ropes for several days, pulling from the rope bridge erected to the opposite bank, and erected five wide iron chain bridges on the Liao River. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Hundreds of thousands of troops crossed the Liao River from the four chain bridges in a steady stream, and the logistics materials were specially vacated for transportation on a chain bridge, and after the army passed, the five chain bridges will be used to ensure logistics.

After crossing the bridge for a few more days, this bridge is no better than the ground, can not march intensively, leaving 20,000 horses to guard both ends of the bridge, this is the lifeline, if it is destroyed, hundreds of thousands of troops will have to starve to death in Goguryeo.

"Where is Guy Suwen now?" The big tent of the Chinese army, Li Er is in high spirits, after crossing the Liao River, the supply can keep up, and the more than 200,000 troops face more than 200,000 troops and hundreds of thousands of people in Gai Suwen, Li Er is not stunned at all.

This Gai Suwen is from the Yuan family, to be precise, it should be called Yuan Gai Suwen, his old man is the Goguryeo Da Lu , that is, the prime minister, who holds the military and political power of Goguryeo.

This Gai Suwen is only twenty-four years old this year, if it weren't for the old man in the family, how could it be his turn to lead hundreds of thousands of horses. Gai Suwen had already learned that the emperor of the Tang Dynasty personally commanded an army of 300,000 to come, taken in the Tang Dynasty to destroy the power of the Turks, and did not dare to fight in the field, and the army was distributed in Xincheng, Liaodong City, Baiyan City, Gaimu City, Anshi City, and Houhuangcheng, and was deployed along the Qianshan Mountain Range.

Xincheng was closest to the Liao River and was an important town for Goguryeo to defend against the Central Plains Dynasty and nomads, and Gai Suwen deployed 50,000 troops and 20,000 people here, and if the Tang army attacked the city, the rear could support it.

"Gai Suwen is now in Liaodong City, but we need to attack the new city first, otherwise the road will be unstable." The scouts and meticulous work had already sent back the information, and Li Jing had already prepared and answered them fluently.

"How many people are there in the new city, and how is the city defense?"

"In the new city, there are 50,000 soldiers and 20,000 people, the city defense is strong, and there is rear support, which cannot be obtained for a while." Li Jing was already familiar with this new city, and he didn't figure out how to break through the new city after thinking about it for a long time.

Going out to fight, three thousand miles away from Chang'an, what kind of siege and reinforcement is asking for a dead end. Goguryeo had already hoarded a large number of grain and grass materials, and the Tang Dynasty needed to continuously transport grain and grass from the rear.

If the 300,000 army is protracted in the Goguryeo War, the Tang Dynasty, which has only been founded for ten years, is likely to be directly dragged down, so what this war needs is a quick victory.

Even if Goguryeo can't be destroyed, it is impossible to stay in Goguryeo for too long, and it will soon be autumn, and the war must end in autumn, otherwise when winter comes, the north will be snowed heavily, the transportation of grain and grass will be blocked, and the soldiers will not be able to adapt to the severe cold in the north, and it is very likely that Goguryeo will take the opportunity to be completely destroyed.

Li Ergang was still in high spirits, and was beaten by Li Jing's stick, the new city must be fought, but the city defense is strong and difficult to capture for a while, this first battle is a big trouble, the back is full of mountain cities, easy to defend and difficult to attack, don't you have to fight, just strike the army and truce, go back to the wife and children to hot kang?

"How's that going to be?"

Lin Feng was wearing a scholar's uniform and took a fan in that fan, the weather was still quite hot, although he was no longer afraid of the cold and heat, but his psychology still did not change.

Li Er looked at Lin Feng and became angry, let's discuss the military plane here, you take a fan there and swing it left and right, are you pretending to be forced to come to Goguryeo, the counselor military plane doesn't know what to do!

"Lin Feng, is there a magic way to break the city?"

Lin Feng put away the folding fan and slapped it twice on his left hand: "It's not easy to break the city, isn't there a grenade in the army, throw a thousand eight hundred and put them under the gate of the new city, pour fire oil, and then ignite it with a rocket from a distance, and the city gate and buildings will be blown away." ”

Li Jing came out: "There are two urn cities at the gates on all sides of the new city, and the gates of the urn city are broken, and after entering the urn city, they are surrounded on all sides, and they can't enter or retreat, so they won't die?" ”

There are two kinds of urn cities, one is built outside the official city gate, and the other is inside, and the function is the same, to prevent the weakest defense gate from being captured.

The urn city is like a bungalow without a ceiling, after breaking the city gate and entering, there are walls on all sides, and if you want to go further, you have to break another city gate, not forward, the archers on the four walls are not vegetarians, even if there are big shield soldiers, the city defense also has stones, and there are many smashing flattens.

Lin Feng spat and scolded: "Goguryeo actually learned to repair the urn city, it's all you losers, teach all good things!" ”

The monarchs and ministers lying on the guns were confused, what are we teaching, how can we teach this city defense, how can we teach it, but our Central Plains city is there, look at what is going on, do you still need to teach?

"Goguryeo New City has been built for a long time, hundreds of years of construction, and the city fortifications are naturally complete." Li Jing looked at the map and said.

After Lin Feng finished complaining, he asked: "Can the army carry gunpowder, dig a big pit under the city wall, and get a thousand catties of gunpowder to blow up the city wall, there is no urn city." ”

"That gunpowder can blow up the walls?" Li Er asked suspiciously, it's not that we haven't seen the grenade, relying on fragments to kill, the bottom of the city wall of the new city is more than ten meters thick, all of which are made of boulders on the mountain, plus Sanhe soil, which is strong and abnormal, not much worse than Chang'an City.

Lin Feng snorted twice: "Don't worry, although the power of black powder is not good, you have made a lot of it, and you will still blow up the city wall." If you don't feel at ease, then let the howitzer fire, and it will definitely be gone. ”

Li Eryi waved his hand: "Just use gunpowder, Li Jing, use all the gunpowder in the army and blow up the city wall." ”

Li Jing immediately arranged for manpower to transport gunpowder, as for the bombing of the city wall, it was not the business of the Chinese army, it had to be done by the former lieutenant Chi Gong, and it was not yet time for us to go out.

When the front army dealt with Xincheng, Li Er began to divide his troops, and he couldn't wait for hundreds of thousands of people on the bank of the Liao River to capture Xincheng before leaving, which was really a waste of time and food.

"Qin Qiong, led 50,000 soldiers and horses to the north to attack Houhuang, Hengshan, Momi, Maigu and other cities; Hou Junji led 10,000 horses to Xincheng, assisted Wei Chigong in attacking Xincheng, attacked Gaimu and Anshi in the south, and joined the naval army to attack Shabei and Jian'an; I led 120,000 Chinese troops to attack Liaodong, Baiyan, Wuguo and other cities, and I will meet for a while. ”

Lin Feng rolled his eyes beside him, Qin Qiong was really unlucky, in addition to the four cities mentioned by Li Er in the north, there were also important towns such as Xuansu City, Yincheng, and Weiyu City, so it was given to 50,000 people, and the demonstration~ parade was not enough.

It is much easier to attack by land and water in the south, and the most troops are Li Er himself, but to face the main force led by Gai Suwen, don't look at the three cities, but the solidity is not much worse than that of the new city, and it is still built on the mountain, the defensive pressure is smaller, and the siege party is more difficult to attack.
