Siege warfare, fighting is also a kind of momentum, whether it is offensive or defensive, momentum is quite important, if one side of the army is unstable, the fighting spirit is weak, it will not last long at all.

Xianbei people have risen in the grassland for decades, they defeated the invincible Xiongnu, became the new grassland overlord, this grassland overlord status, so that the self-confidence of the Xianbei people has been greatly improved, in the usual battles, they are invincible, invincible, so this attack on Yanmen Pass, they rely on a huge number of advantages, confident that they can easily take Yanmen Pass.

Although the army defending the city on the Wei side did not come from the same army, whether it was the county soldiers who originally defended the city or the Yue cavalry who had experienced a hundred battles, even if it was a slightly inferior Tun cavalry, in terms of fighting will, it was not inferior to any army.

Cao Liang is quite rigorous in governing the army, from the time of the formation of the Pingbei Army, he pursued the line of elite soldiers, not many soldiers but fine, all the soldiers who joined the Pingbei Army have undergone strict assessment, survival of the fittest, so as to ensure the quality of the soldiers.

With high-quality soldiers, it is natural to have a remarkable effect in improving combat effectiveness, especially the Vietnamese cavalry, which is the army brought out by Cao Liang, although the scale of the Vietnamese cavalry is now larger than before, and the number of new members accounts for the majority, but the spirit of the team does not collapse, and the fighting spirit does not disperse, and they will always be a division of victory.

Although they adapted to the rhythm on horseback, the Yue cavalry abandoned their horses to defend the city, and they also fought very beautifully, not to mention, they were facing the Xianbei cavalry who were also accustomed to riding battles.

Compared with the single offensive means of the Xianbei people, the Wei army is varied in defense, and the weapons used are also varied, compared to the bow and arrow, the efficiency of rolling wood and stone is higher, the bow and arrow can only be killed, and an arrow can only kill one enemy at most, but the rolling wood and stone are different, it can cause the enemy to be killed in groups of casualties.

But the most effective, but not these two weapons, the most powerful weapon in the defense of the city is the boiling oil, on the top of the city, boil a large cauldron, pour all kinds of grease into the pot to melt and boil, scoop it up, pour it from the city.

The boiling oil is hotter than hot water, and once it is poured on the heads and faces of the besieging Xianbei soldiers, it will immediately burst out with a howl like killing pigs, and almost no one can bear such a pain.

Of course, killing and injuring enemy soldiers directly is one way to boil oil, but the more powerful ones are in the back, because the enemy soldiers can use shields for protection, and they are also protected by leather armor, as long as they avoid being poured with boiling oil on the exposed skin, it seems to be safe.

In fact, boiling oil has a bigger killing move, which is also what it is more powerful than boiling water, that is, boiling oil can be ignited, when enough boiling oil is poured down, the Wei army can throw torches on it, and the grease poured on the Xianbei soldiers and ladders will be ignited.

The slightest bit of grease is ignited, and a raging fire will immediately ignite, and the Xianbei soldiers and those ladders that have been drenched in grease will be burned in the flames.

This method of destroying people with ladders is the most violent, and it is also the most effective method of demoralizing the enemy, not only can severely damage the Xianbei soldiers who are besieging the city, but also burn their siege equipment, and the psychological shadow brought to the Xianbei people is naturally extremely huge.

But the battle continues, after all, the amount of boiling oil is limited, and it takes a long time to melt the oil to boil, so although boiling oil is the most lethal weapon, it is ultimately limited by quantity and cannot be applied on a large scale.

Otherwise, no matter how many ladders the Xianbei people erected, they would all be solved if they poured boiling oil one by one.

Tuoba Li, who supervised the battle behind the battle, gradually became solemn from relaxed, and the Yanmen Pass, which he thought could be easily won, would be so stubborn, and the city was full of countless corpses, which was the price paid by the Xianbei people.

Of course, Tuoba Liwei will not feel sorry for these dead soldiers, as an ambitious and courageous Xianbei king, it is destined to step on countless corpses, just like when he killed his wife, in order to seek power, it is worth sacrificing anyone or anything.

But what made Tuobali slightly depressed was that after paying such a heavy price for casualties, they still failed to climb the city wall by half a step.

But since he has won this role, Tuoba Liwei will never waver, and taking Yanmen Pass is his established goal, so he must take it at all costs.

Xianbei's attack did not stop because of the unfavorable attack, the Xianbei people's fierce and fearless strength of death, but also seemed to be much stronger than the Huns, and in several battles of the state, the Wei army captured a large number of Xiongnu prisoners of war, once these people were defeated, they completely lost their fighting spirit, and surrendered early.

But the Xianbei man in front of him didn't seem to know what fear was, even if he had been a brother and died tragically in front of him, he couldn't be moved.

The Wei army has already lost count of the Xianbei people who have killed and injured them, just looking at the corpses all over the city is already shocking, and as time goes by, more Xianbei people will die under the city.

Because Yanmen Pass is a pass, both sides are high mountains, there are not many areas that can be attacked by Xianbei people, so even if the Xianbei people have 100,000 troops, but the troops that can really be put into the attack are relatively small, and the Xianbei people only use the way of rotation attack, one after another, and can not use the Yanmen Pass to be surrounded on all sides.

Since the Wei army only needs to withstand one side of the attack, the pressure on the entire city defense will not be too great, as long as they stick to their positions and fight bravely, it will be difficult for the Xianbei people to break through this defense line.

The offensive and defensive battle of the city was originally a clash of perseverance between the two sides, and whoever could hold on to the end would be victorious.

The failure of the continuous attack hit the originally high morale of the Xianbei people, and seeing the red sun sinking in the west and the sky getting twilight, Tuoba Liwei had to order Mingjin to withdraw his troops and temporarily stop the attack.

The Xianbei people quickly evacuated the city like a low tide, and the Wei army fought for a day, and they also felt a little tired, but Deng Ai Shibao and they all knew that this was just a beginning, and the Xianbei people's attack would not be stopped because of today's defeat, and they would definitely launch a more fierce attack tomorrow, and more brutal battles were waiting for them later.
