"Huh? The Goguryeo general on the city wall also seems to be holding a clairvoyant? Just as Li Xiu was looking at the head of Anshi City, Cen Wenwen next to him suddenly said in surprise.

In fact, Li Xiu also saw it at this time, there was a middle-aged man in armor standing on the opposite side of the city, holding a Tang Army-style clairvoyant in his hand, looking at them, and looking at the banner around this person, it should be the city lord of Anshi City.

Seeing the telescope in the other party's hand, Li Xiu didn't look too surprised, but said very calmly: "Although clairvoyance is the equipment in our army, there have been occasional generals who have died in battle in recent years, and the clairvoyance on their bodies has naturally been lost, so it is not impossible for Goguryeo nobles like the city lord of Anshi to have clairvoyance in their hands." ”

"I see, but even if this is the case, the number of clairvoyants lost outside should not be much, and the appearance of one in the hand of this Anshi City is enough to show that this person's status in Goguryeo is not low!" Cen Wenwen continued after listening to Li Xiu's words.

"Hehe, this Anshi City Lord is indeed very special in Goguryeo, Jingren, do you remember King Rongliu who was killed by Quangai Suwen before?" Li Xiu knew something inside, so he smiled again at this time.

"King Rongliu? Could it be that this city lord of Anshi has something to do with King Rongliu? Cen Wenwen couldn't help but be surprised when he heard this, before the civil strife in Goguryeo, King Rongliu died at the hands of Quangai Suwen, and the Tang Dynasty also took advantage of this opportunity to send troops, and even the banner was to administer justice to King Rongliu, and to eradicate Quangai Suwen, a rebellious minister and thief.

"Yes, as far as I know, this city lord of Anshi is surnamed Yang, but he is the henchman of King Rongliu, some time ago King Rongliu died at the hands of Quangai Suwen, and then Quangai Suwen set up a new king, asking the city lords to be loyal, but this Yang city lord would rather die than obey, as a result, Quangai Suwen was annoyed and led his troops to attack Anshi City, but unfortunately in the end it was in vain, if it wasn't for us to come in, I'm afraid there would be a big conflict between Quangai Suwen and this Yang city lord!" Li Xiu said with a smile at this time.

"Oh? That Yang City Lord seems to be a loyal and righteous person, and he will not give in even if the old master dies! Cen Wenwen couldn't help but show an expression of admiration when he heard this, he was a scholar, and he had always had a good impression of this kind of loyal person.

"Yes, this Yang City Lord is indeed loyal to King Rongliu, but he has a conflict with Quangai Suwen, but he also does not welcome our Tang Dynasty, it seems that he is not only loyal to King Rongliu, but also loyal to Goguryeo!" Li Xiu said indifferently at this time, although this Yang City Lord looks like a Han from the surname, but because of the prosperous culture of the Tang Dynasty, many small countries around him envy the prosperity of the Tang Dynasty, so he changed his Han surname, so no one knows if he is Han or not?

"Hehe, although we are under the banner of upholding justice for the King of Rongliu, as long as anyone with a little knowledge can see our true purpose, but although this Yang City Lord is loyal, I am afraid that in the end, I can only bury Goguryeo!" When Cen Wenwen said at the end, he couldn't help but show a look of regret on his face.

Li Shimin brought 30,000 troops, plus the 40,000 troops in the hands of Li Ji and Cheng Yanjin, although some of them were left, but there were more than 50,000 people together, which is not a small number, not to mention that there are 20,000 people under Zhang Liang, such a powerful force, even the original Turks could not stop the footsteps of the Tang army, let alone a small Anshi city.

Hearing Cen Wenwen's words, Li Xiu nodded noncommittally, although he believed that Datang should be able to conquer Anshi City, but it would never be as simple as Cen Wenwen or Li Ji imagined.

Li Shimin's army arrived at the city of Anshi and rested for three full days, and at this time there was news again that 150,000 reinforcements from Goguryeo were about to arrive in Anshi City the day after tomorrow, speaking of Goguryeo's military intelligence, it is generally not so easy to leak, but before King Rongliu was killed by Quangai Suwen, which led to the division of Goguryeo, although Quangai Suwen used high-pressure means to make many people take refuge in him, but there are still some people who are loyal to King Rongliu, coupled with the secret contact of the Tang Dynasty, So now some nobles of Goguryeo have secretly taken refuge in the Tang Dynasty and sent some information to the Tang Dynasty from time to time.

"Kill, kill, kill~" With Li Shimin's order, tens of thousands of Tang troops rushed to Anshi City murderously, Li Shimin planned to take advantage of the fact that the reinforcements had not yet arrived, to test the reality of Anshi City, after all, when Li Ji came here before, he had never attacked, and even camped far away from Anshi City.

Li Ji personally commanded an army of 20,000 to kill Anshi City, and the crossbow arrows and trebuchets were also pulled to the front of the formation, with the flash of the Ling flag, countless crossbow arrows flew to the city first, but the Goguryeo people at the head of the city had already erected their shields, and the effect of the crossbow arrows was not obvious, but then the trebuchet began to exert its might, if it was just a simple trebuchet, the effect was also limited, but the Tang army used fire oil bombs and gunpowder bullets.

For a time, the flames on the head of the city of Anshi were soaring, and the sound of explosions also rang out, and countless Goguryeo people were either blown off the city, or jumped off the city on fire all over their bodies, and the defense on the city was completely disrupted.

As a famous general, Li Ji naturally will not miss this opportunity, with the order issued by his side, the cloud echelon and siege vehicles that have been preparing for a long time also immediately followed, and the crossbowmen in the rear also desperately shot arrows to suppress the Goguryeo people at the head of the city, it can be said that everything seems to be very smooth, and it seems to be no different from the previous siege battle.

Seeing that the ladder was built on the city wall, the siege vehicle was also pushed to the side of the city wall, and the soldiers with shields below also climbed to the high place along the siege vehicle, while shooting arrows at the top of the city to suppress the enemy army, and at the same time lowering the drawbridge on the roof of the car and building it on the head of the city, so as to facilitate the soldiers below to climb the car and rush to the head of the city.

The siege vehicle is actually a general term for a siege machine, which is also divided into many types, such as the rushing car that attacks the city gate, in fact, it is a heavy solid wood with four wheels under it, and the use of inertia to impact the city gate, and there is also a kind called the city car, that is, the siege vehicle used by the Tang Army now, simply put, it is a tall ladder with wheels, which is generally higher than the city wall, and when it is used, it is pushed to the side of the city wall, and the soldiers above shoot arrows downward, and the soldiers below climb up along the ladder, and then put down the suspension bridge on the top and build it at the head of the city. Then follow the drawbridge to the top of the city.

The soldiers of the Central Plains Dynasty are good at defending the city, and they are also good at attacking the city, such as these siege equipment, which are not made by ordinary small countries, especially the tall boarding car, which requires extremely high craftsmanship, which is usually disassembled and carried, and then assembled by craftsmen when it arrives on the battlefield, and only the army of the Tang Dynasty has the ability to carry a large number of craftsmen.

"The soldiers are about to climb the city wall, and it seems that there is nothing special about this Anshi City." Li Shimin also looked at the city in the distance with a telescope in his hand at this time, and he also had a very relaxed smile on his face.

Before, Li Ji was worried that Anshi City was not easy to fight, after all, after this period of observation and intelligence collection, it showed that this Anshi City Lord was not an ordinary person, but now it seems that Li Shimin is a little worried that if Anshi City is defeated, will it scare away the upcoming Goguryeo reinforcements?

However, as soon as Li Shimin's words fell, there was a sudden change in the head of the city of Anshi, only to hear a loud horn in the city, and then a group of Goguryeo soldiers rushed to the city, and these people held torches in their hands, holding a leather bag in their hands, and after igniting it, they went to the car on the boarding car, and the leather bag was also filled with fire oil, and the fire was ignited on the siege vehicle in the blink of an eye, and the soldiers above had no time to escape, so they could only jump down with a scream, some were lucky enough to jump into the moat, and some fell directly to the ground.

More than a dozen boarding cars turned into more than a dozen huge torches in the blink of an eye, even if the cars had been wet in advance, but they couldn't stand the burning of the fire oil, and as these most threatening climbing cars were burned, those ladders on the city wall were also pushed down one by one, even if the fire oil bombs and gunpowder bombs in the rear kept firing at this time, but the Goguryeo people at the head of the city seemed to be crazy, regardless of any casualties, even if some Tang soldiers were lucky enough to get to the top of the city, they were still held by some Goguryeo people and jumped off the city, In the end, it fell into two puddles of flesh that did not distinguish between you and me.

It was not the first time for Li Xiu to participate in the war, when he first attacked the Turks, he had also witnessed the tragic situation of the war, but the Turks were nomadic people, and there were no cities worthy of the Tang army's attack, but the cities on the Goguryeo side were built very strongly, which also made him see the cruelty of siege warfare with his own eyes.

Even Li Xiu was secretly thinking to himself at this time, although the Tang army was equipped with some firearms, the combat methods used still belonged to the era of cold weapons, if it was the era of rampant hot weapons in later generations, the war would definitely be a hundred times more cruel than now, but he had not experienced war in later generations, and he could not imagine the true appearance of war in later generations.

Li Ji's first wave of attack was quickly blocked, of course, the main reason was that he saw that the casualties were too large, and it was impossible to capture the city in one fell swoop, so he ordered the troops to retreat, and then organized the second and third attacks, but the defense of Anshi City was very tenacious, even if the Tang army attacked the city several times, it was still beaten by them in the end.

Li Shimin in the rear saw this, his face also became a little unpleasant, although this was only a tentative attack, the Tang Army did not show its real strength, and he did not want to take down Anshi City, but it still made him understand the tenacity of Anshi City, it seems that he did underestimate this Anshi City before.

After three tentative attacks, Li Shimin ordered the troops to retreat, and this attack made no other progress except for adding countless souls to the city of Anshi, and this also cast a shadow on Li Shimin's imperial conquest.
