Shibi Khan did not know that his whereabouts had been discovered by the Sui army scouts, the vanguard of the Turks had arrived at Liangushu on the Ulan Mulun River at this time, this is a fortress built by the Sui army outside, this kind of fortress is thirty miles a, mainly playing the role of early warning and providing the sentry soldiers to rest on their heels, Liangushu belongs to a relatively large fortress, which is stationed more than 500 Sui soldiers, but after they saw the Turks going south, they had already lit the beacon fire, abandoned the fort and could not escape, with 500 people against hundreds of thousands of people, Obviously, the Sui army did not faint.

This force was the vanguard of the Turks, led by Ashina Shibabi, the son of Shibi Khan, who would later become the Turkic Khan.

His army has advanced from the pass of the Yinshan Mountain Range to the south for nearly a thousand miles, but there is still no receipt, the Han people seem to have been alerted, a large number of herdsmen and border households under the foot of the Yinshan Mountain have long disappeared, and there is no figure to see along the way, which makes him very angry, this time he and his brothers led the troops to attack, and he is the main force along the way, and there is also the 300,000 army of his father Khan, if he can't achieve something, he will be directly seen by his father Khan, On the other hand, because there are fewer troops and the task is lighter, if the results are achieved, it will definitely attract the attention of the father Khan, so Shi Bobi must get the results before his younger brother.

Shi Bobi set his sights on the silver city in the south, which was the northernmost city in Diaoyin County and the border city closest to the Great Wall.

The Great Wall here is not the Great Wall built during the Qin Dynasty, the Great Wall built more than 200 years BC has long been weathered and decayed at this time, and the Great Wall in the north of Yincheng is the Great Wall of Sui built during the period of Emperor Wen of Sui, mainly to resist the increasingly powerful Xiongnu in the north, but with the increasing decline of the Xiongnu, so in the later period of Emperor Wen of Sui, the funds allocated by the imperial court to repair the Great Wall at the border pass have also been greatly reduced, so the Great Wall is actually not very strong, and basically it has not played a great effect.

Shi Bobi's 100,000-strong army easily crossed the Great Wall and came to Guannai, preparing to attack Yincheng.

Although the Turks' siege equipment was relatively crude, it was not completely absent, but weapons such as trebuchets and large bed crossbows were obviously impossible to make, so siege was not a good choice for the Turks, even after more than 600 years, when the cavalry of the powerful Mongol Empire swept across the entire Eurasian continent, their cavalry troops could not take some fortified cities.

Therefore, for cavalry, especially light cavalry like the Turks, luring the opposing army defending the city out of the city and then conducting a field battle is undoubtedly the most ideal way to fight, but how to lure the Sui army out of the city is indeed a problem.

The number of Sui troops stationed in Yincheng was originally not very large, only less than 1,000 people, such a force for the number of 100,000 Turkic cavalry, even if it is a hard attack is not difficult to win, but after the Sui army got the alarm, Qu Tutong hurriedly rushed to Yincheng with 50,000 troops overnight, which greatly improved the defense ability of Yincheng.

However, Yincheng is a small border city, and it is unlikely that all the 50,000 troops will be stationed in the city, so Qu Tutong sent 20,000 troops to each of the two high places outside the city, forming a corner with the army in the city to resist the attack of the Turks.

Shi Bobi led the army and chose to destroy the two Sui troops outside the city first, although the Sui army's large camp had a wall as high as a battle, as well as trebuchets and bed crossbows, but compared to the strong city walls, these things were obviously easier to destroy.

The Turks chose to block two sides and attack the other, and Shi Bobi sent 60,000 troops in three batches to attack the large camp on the left outside the Sui army, and then sent another 30,000 troops to block the support of the Sui army in the other two directions, so that they could not threaten the attacking Turkic army.

The Turkic attack was very fierce, a large number of infantry with shields, covering the archers and siege cones behind the Sui army camp, tens of thousands of cavalry on both wings of the rapid cruising and towards the camp arrows, while killing and wounding the defenders, while distracting the defenders, these cavalry horses with ropes, once they caught the opportunity, they would approach the board wall, with a lasso horse rope to cover the board wall, and then more than a dozen cavalry worked together to pull the board wall apart, for a time the Sui army's board wall appeared dozens of defects, A large number of soldiers with crossbows and arrows in their hands and shields were holding off the attacks of the Turkic cavalry.

But these are not the most deadly, the most deadly is that under the protection of a large number of shield soldiers, the Turkic siege cones have approached the camp, and the board wall is not a city wall, so naturally it cannot resist this powerful weapon.

"Bed crossbow, aim at the Turkic siege cones, ready! Put! ”

A general of the Sui army ordered loudly, and more than ten bed crossbows were fully wounded under the operation of more than 300 soldiers. With a sound, more than a dozen heavy crossbow arrows shot out from a high place, and crashed into the formation of the Turks in an instant, the round shield in the hands of the Turks was originally covered with a layer of iron, mainly used to resist the bows and crossbows of the Sui army, most of the bows and crossbows of the Sui army are triangular arrows, so the use of iron can greatly weaken its penetrating power, reduce the killing effect, and protect the soldiers behind the shield, but this round shield is as vulnerable as paper paste in front of the bed crossbow.

The thickness of the arrows used in the bed crossbow is not much different from the spear in the soldier's hand, their strength is huge, the use of composite bowstrings, a bed crossbow needs to use three to five bowstrings, so the strength is very strong, the soldiers have to use the winch to give the bed crossbow strength, this process is very slow, and it is also very laborious, it requires at least a dozen soldiers to operate together, so its rate of fire is not fast, and it can only fire three to five arrows at most in a quarter of an hour, this rate of fire is far less than the bow and arrow, not to mention the crossbow arrows, So unless it's against some very solid targets, or in a large defensive battle, the average army won't use it, because it may not be useful.

After a dozen stout crossbow arrows were shot into the middle of the Turks, they instantly took the lives of dozens of soldiers, in order to protect the safety of the soldiers pushing the siege cones, so the Turks' formation was very dense, and the movement speed was also very slow, so this was obviously an excellent target for bed crossbows.

The bed crossbow was fired, and the Turks left corpses all over the place, and they were horrified to find that many soldiers had been pierced to death, and even four or five corpses were strung on the long arrows of a bed crossbow, and their trusted shields were directly reduced to pieces under the attack of the bed crossbow, and they were scattered all over the ground.
