Qi was the main attack on Tongguan, and all the troops of the Northern Zhou Dynasty went to Hongnong, and Gao Yanzong rushed to Xiazhou and had the momentum to attack Chang'an. Although he was repelled by Xi Changru, Guazhou, under this situation, Wei Xiaokuan had to support Huluguang's attack of 100,000 tigers and wolves alone... Especially when Duan Shao fought his desperate efforts to resist the attack on the northern surroundings, Huluguang's attack on Yubi became more and more fierce, and Wei Xiaokuan gradually became difficult to resist.

Originally, the main attack direction of the Qi army was not here, and waiting for the help was the best strategy for Huluguang, but why was Huluguang so anxious to open the jade bi?

First of all, we need to start with the terrain of Yubi. This area is mostly the Fen River Valley, connected to Jinyang in the north and the Yellow River Ferry at the junction of Jin and Shaanxi in the south. This is the shortest way to attack Guanzhong, and undoubtedly the fastest way.

The greatest military significance of the southern Shanxi Basin to the Northern Zhou Dynasty was Pujin Ferry, Longmen Ferry and Fengling Ferry. Liu Yong surrendered to Qi. In Fen, Jiang, Huluguang, who was eyeing him in a covetous manner, immediately sent troops to sweep him, causing great trauma to the Zhou army entrenched here. When the emperor issued an edict to expedition the west this year, Huluguang captured Fengling Ferry and Puban again, which was undoubtedly the fastest.

When the Eastern Wei attacked the Western Wei, in order to facilitate and fast, they ordered people to open a new tunnel in the valley next to the old Qianli Path, so that the Eastern Wei army would not have to cross the mountains from now on. Instead, this also gave the Western Wei army extremely great convenience. Wang Sizheng, a famous general of the Western Wei Dynasty, built Yubi City here in a convenient location. This kind of strategy was never expected by the Eastern Wei.

According to traditional thinking, to prevent the enemy from attacking Guanzhong, the first thing to do is to guard the ferry. As long as each ferry is still in the hands of the Western Wei, the six iron horses from the Eastern Wei and Jinyang cannot attack Guanzhong. As for extending the Yellow River defense system to Jade Bi, no one has ever thought about it before.

But Wang Sizheng saw this. After the Battle of Shayuan and the Battle of Heqiao, the East and West Wei generals began a long-term confrontation. The situation between the East and West Wei had solidified. Gao Huan moved the capital to Yecheng, and Henan was empty. The defense line in the Hedong area of ​​the Western Wei Dynasty would face the threat of a 100,000 troops of the Eastern Wei Dynasty. Although Puban was in the hands of the Western Wei Dynasty, he was still worried, so he gave Puban another insurance.

This insurance is Jade Bi. I don’t know what it felt like when the Eastern Wei army rushed from Jinyang to the south. I guess anyone would look good... Because the city was so strategically targeted for the Eastern Wei, it can not only control the path of the Eastern Wei westward, but also gradually erode the land in southern Jin and then threaten Jinyang.

Yubi City was located on a flat highland and was surrounded by a river. There was no threat of water cut off. Moreover, Yubi City was four kilometers long and occupied almost the entire platform there. It can be imagined that for the attacking Dongwei, the Eastern Wei, it was a dangerous place to kill. The Eastern Wei used his flesh and blood to attack the city, and suffered heavy casualties, but he could not do anything to the Yubi.

Logically speaking, since the Northern Qi Dynasty has paid more and more attention to Pingyang in recent years and built a large number of military buildings in Fenzhou, Yubi's strategic position has been greatly reduced. As long as Huluguang continues to fight with the Zhou army in Fen and Jiang areas, he will not let him return calmly, it will play his role. His attack on Yubi is not of much benefit to the Qi army, but in fact, Huluguang saw the huge threat hidden in it and had to take this inferior plan.

This fatal threat came from Duan Shao's troops. Duan Shao was in charge of Huayin and controlled Puban and Fenglingdu, which corresponded to Dugu Yongyeyao in Huazhou. Previously, the Zhou army wanted to quickly attack from the Yellow River Ferry, but was blocked by Duan Shao's iron cable blocking. Zhao Zhongqing planned to ambush the Qi army, which was also discovered by Duan Shao, but Duan Shao's troops were severely dispersed and not enough to fight against the Zhou army.

In particular, Yuwen Yong slapped his head and stepped up to eliminate the threats behind him. Although he seemed a little too easy, he undoubtedly shook an important part of the Northern Qi strategy. Moreover, Duan Shao has been in poor health in recent years... To make the worst estimate, if Duan Shao and Huayin had any accidents, the Zhou army would inevitably seize Puban again. If Fenglingdu was further recaptured, the consequences would be really unimaginable!

The most important transportation of materials for the Northern Qi army was pulled out, and His Majesty's 200,000 troops would even be a problem for food. How easy is it to run back to Hangu from Tongguan? It has to pass through a narrow passage that lasts 400 miles and face the full pursuit of the Northern Zhou army. It is really like there is no way to go to heaven and no way to go to the ground...

Then, the situation is already obvious, and Yubi will definitely be the biggest threat to his westward support!

Even if this city cannot be removed in one fell swoop, the main force of the Zhou army must be completely abolished.

Therefore, Huluguang's main strategy changed from waiting for aid to take the initiative, and strived to use absolute military advantage to siege the city and attack the aid, and attempted to have a decisive battle with Yuwen Xian and Wei Xiaokuan in the Fenhe Valley to completely smash all the strength of Zhou State here so that he could move west with confidence. Maybe he could take Chang'an in advance.

As an old opponent for many years, how could Wei Xiaokuan not know what Hu Luguang's idea was? But he had no choice. He was struggling to hold on under the fierce attack of the Qi army, rolling in blood.

Originally, Wei Xiaokuan's pressure was not as strong as this. Yubi's geographical location was unique. There were two enemy buildings in the south of the city. In order to firmly occupy the commanding heights, Wei Xiaokuan had more high enemy buildings, with the purpose of preventing the Qi army from building up a mountain of earth and a high platform to shoot at Yubi.

In addition, whether it is to attack the water source or dig tunnels to attack, it is proven to be undesirable. If Huluguang really does this, Wei Xiaokuan cannot ask for it. Whether it is to build soil mountains or dig tunnels, it is very mental and physically exhausting, and it just drags Huluguang to death.

After Qi army used gunpowder, Wei Xiaokuan's psychological pressure increased greatly. Just yesterday, Qi army set up a throwing cart and threw a can of gunpowder into it. The attacks were very dense. One of the enemy buildings was actually collapsed, and the Jade Bi city walls also cracked in many places. Fortunately, Wei Xiaokuan ordered people to dig out the tunnel in order to prevent problems before they happened. Although the losses were a little heavy, they could still support it for a while.

The most important thing is that Yubi only has two enemy buildings in the south of the city, which is entirely due to these two enemy buildings covering the front of the city wall that lasts for two miles. It is not as powerful as it is now destroyed, which makes it even worse... In other words, when the Qi army attacked the city, it only needs to bypass the other one far away and pile a gentle slope with sandbags in a remote area to successfully attack the city.

Therefore, the first thing Wei Xiaokuan did to get out of the tunnel was to send additional people to the city wall on the south side, shoot with a hard crossbow to suppress the siege speed of the Qi army. Huluguang also used a large killer weapon - an attacking vehicle, which can be hit, hooked, or climbed. There was even a flying tower on the roof, similar to a ladder, which could help soldiers walk and assist the siege to climb directly to the top of the city.

Although the attacking car was powerful, it was very bulky. You can imagine how much the price Huluguang paid. However, as the best guard in the world, Wei Xiaokuan had no two brushes? He asked someone to use a huge spliced ​​oil cloth to block the sight of Qi Jun who controlled the attacking car, and then poured tinder oil to make the attacking car burn.

Secondly, the large wooden fence kept transporting to block the gap and filled the bricks and stones to reinforce it. Qi army still returned in vain. Huluguang realized that if this continued, he would probably be exhausted, so he personally shouted in front of the formation:

"Wei Xiaokuan, you must have been exhausted after sitting in Yubi for so long. This city will be destroyed by me sooner or later, so why not surrender early? My lord is a wise king and always loves talented people. If you surrender to me, you will be the king and the title of the king in the future, it is unknown!"

Wei Xiaokuan knew that this was Huluguang's plan to attack his heart. If he did not respond, his morale would be greatly hit. So he came to the city at the risk of being shot by crossbow arrows and shouted loudly:

"Hulu Mingyue, you old man! Don't think of ruining my righteousness! My Yubi City has sufficient troops and food and grass. I am not afraid of you. I just wait for the reinforcements of King Qi to arrive and attack inside and outside immediately, and ask you, tens of thousands of mobs, and there will be no armor left!"

Huluguang sneered and responded neatly: "Excellent, I didn't expect that after a long time of no see, the old turtle of Wei Xiaokuan, you, also have a huge voice! I might as well tell you, let alone Yuwen Xian, the younger generation, even if it was Wang Sizheng who was alive, I wouldn't be afraid of him!"

Wei Xiaokuan was about to scold him, but suddenly he saw a flash of white light in front of him. He quickly turned his head and a soldier fell heavily behind him. On his forehead, a short crossbow passed through his helmet. The white brain mixed with blood splashed out, sticking to his boots spots... What a vicious crossbow!

Wei Xiaokuan immediately had a huge soul and was furious and ordered the crossbowman to shoot. However, the Qi army took the initiative and the Zhou army counterattacked in a very embarrassing manner. Only a few arrows shot into the Qi army in two or two...

Seeing this, Hu Luguang couldn't help but snorted coldly, pulled out his horse and left. In fact, Hu Luguang also found it difficult to besiege Yubi so calmly. According to the report from the post, Yu Wen Xian had already sent troops to the Five City County, and the sword front was aimed directly at Fenshui Pass!

Before this, Yuwen Xian set up a suspicious formation and pushed Liang Shiyan thousands of men to Dingyang. Huluguang had deliberately let go of the gap, but unexpectedly, he was rebeled and was naturally unhappy. So he summoned the troops to return to Dingyang, sent troops to Dingyang, and sent a group of troops to chase Yuwen Xian. Therefore, Liang Shiyan had just stood in the desert of Dingyang and saw Qi troops swarming in the mountains and fields.

Liang Shiyan formed a car to the camp and stayed north. He ordered the army to say, "Watch and wait and see, behead you! One person retreats, and all the troops will behead you!" Although the soldiers responded in unison, the voices were not yet extinguished. The Qi army had already arrived and gathered around the Zhou camp.

The Zhou army fought desperately, and from the end of the day, the Qi army was not allowed to attack. Liang Shiyan was severely injured and still tried his best to support him and invited everyone to fight.

At this time, it was the wind gust facing east, which was beneficial to the Qi army. Huluguang immediately ordered Qi Lian to lead the cavalry to dismount and carry grass, and set fire to Liang Shiyan's chariot camp. The Zhou army's formation was in chaos.
