Gao Xiang here, the task of digging the trench was refined, and the effect was soon apparent the next day.

As a result, when the weather was getting colder and the ground was getting harder and harder, the trench excavation project was only carried out for five days, and in addition to the Dajian Pass, there were three more trenches that were four feet deep and four feet wide, and the length was the same as that of the Dajian Pass.

Such a huge and difficult project could be completed in such a short period of time, even the executor Gao Xiang himself was surprised, not to mention Yan Yan, the guard in the Great Sword Pass, and Wu Lan under the Guancheng.

"General, now that winter is approaching, and the injuries on your body are not completely healed, don't go to Guancheng again." The other deputy general in the Great Sword Pass was beside Yan Yan, looked at Yan Yan who was frowning, and explained.

Previously, Wu Lan suddenly led troops to block the Great Sword Pass, sealed the south gate of the city, and dug a trench to further block the way out of the soldiers in the Great Sword Pass. Even so, Yan Yan was not worried at that time, but since Gao Xiang led his troops to reach the outside of the Great Sword Pass, Yan Yan's attitude has changed, and he drags his sick body to stand on the wall of the pass every day, just like now, he looks at it for a long time.

As for the other deputy general of Dajian Pass, Wu Ban had already been ordered by Wu Yi to not only take away the 10,000 soldiers he brought to reinforce Dajian Pass, but also take away the 10,000 soldiers originally stationed in Dajian Pass, a total of 20,000 people.

That is to say, after the failure of the surprise attack on Langzhong County, after learning that his administrative office was lost, Wu Yi transferred more than half of the troops in the Great Sword Pass at that time, and the number of remaining soldiers was less than 20,000 at all.

In the battle of Cheng Lian's sneak attack on Dajian Pass, his side lost a lot of manpower, 3,000 elites killed 300 people and injured 300 people, of which half were disabled after the war.

This is the highest number of dead and disabled soldiers of the 6,000 elite soldiers of the Yellow Turban Army that Jin Jue has been carefully selected from the Yellow Turban Army that has taken refuge in him since the beginning of the war, and has been trained in one winter.

So far, except for the sneak attack on Dajian Pass, the total number of dead and disabled 6,000 elite soldiers of the Yellow Turban Army has not exceeded 100. Among them, good training is one thing, and on the other hand, the combat method of using night raids to steal cities and the powerful power of the golden arm crossbow are also the most important reasons why the casualty rate is so low.

And the casualty rate of the elite soldiers of the Yellow Turban Army is so high, you can imagine how high the casualty rate of the defenders in the Great Sword Pass was in that battle.

The main general Yan Yan was also lucky, but he was shot in the left arm by the crossbow arrow of the golden arm crossbow, this is still, Jin Jue did not let the soldiers take the initiative to use the leaded arrows, if he did this, Yan Yan would have died of wound infection a long time ago.

And the other defenders who were shot and killed by the elite soldiers of the Yellow Turban Army of the Jin Jue Army are countless, and what is even more terrifying is that those injured defenders have a very high mortality rate, and Yan Yan's deputy general tried everything he could, and in the end only saved one percent of the wounded soldiers.

At that time, if Yan Yan hadn't personally come to suppress the bullet and personally drove all the elite soldiers of the Yellow Turban Army sent by Cheng Lian to Guancheng, Dajian Pass would have changed hands long ago. And if Jin Jue hadn't strictly ordered Cheng Lian not to go to the city, Yan Yan would have been killed by Cheng Lian a long time ago.

Of course, swords and arrows have no eyes, except for generals like Xiang Yu or Lu Bu who are superb in martial arts and domineering in their bodies, no one can guarantee that they will be unscathed on the battlefield.

If Cheng Lian didn't listen to Jin Jue's orders at that time and rashly attacked the city wall of Dajian Pass and Beiguan in person, there was a high probability that he would be injured by the Shu soldiers' bows and crossbows, or even shot on the spot.

The Shu soldiers are good at guarding, if there is no Jin Jue, the ability to make bows and crossbows is even more overwhelming. Even Pang Tong's military division died under the arrow, and no one could be spared.

"Alas......! Knowing this, the general should have led his troops out of the city earlier. My lord, the last general is incompetent and cannot go out of the city to rescue you. After listening to the adjutant general's words, Yan Yan suddenly covered his face with his uninjured hand, shook his head again and again and sighed.

"General, now, we can only hope that the lord can send troops to defeat Jin Jue as soon as possible. It is already very rare for us to be able to defend the Great Sword Pass now. The adjutant general explained on the side.

Before, when he was sealed by Wu Lan in the Great Sword Pass, Yan Yan actually had the opportunity to lead his troops to break through Wu Lan's defensive array and defeat Wu Lan's troops and horses. However, at that time, Yan Yan did not receive Liu Zhang's order, and Li Fengzheng was blocking the north of Dajian Pass with tens of thousands of Jin Jue's army 'soldiers', and he did not dare to rashly lead troops out of the pass.

Second, Yan Yan's own injuries are indeed very serious.

Yan Yan didn't expect the situation to deteriorate so quickly, originally he wanted to take advantage of the winter three months later, when it was relatively difficult for the soldiers outside the city to defend the camp compared to the inside of the city, and choose the opportunity to go out of the pass to break through Wulan, and at that time, the heavy snow closed the mountain, even if Yan Yan only left a single soldier in the city, the Jin Jue army in the north of the Great Sword Pass had no way to take advantage of this opportunity to attack the Great Sword Pass.

It's just that Yan Yan never expected that another general of the Jin Jue Army, who suddenly appeared outside the city, would be able to completely destroy his long-planned plan in such a short period of time.

Now, Yan Yan could only watch as there were three more trenches so deep outside the Guancheng he guarded, but there was no way at all. If he chooses to fight at this time, it is no different from looking for death.

Not counting the strong men recruited by Gao Xiang, but the number of soldiers of Wu Lan and Gao Xiang is basically the same as the number of remaining defenders in the Dajian Pass, plus three and a half days of trenches, as well as a strong battalion. Yan Yan knew very well that if he went out of the customs to sneak attack, there was a high probability that before he rushed to the enemy camp, he and all the soldiers under him had already been shot and killed by the enemy.

What's more, Yan Yan knew that the morale of the soldiers in the Great Sword Pass was extremely low now, and there would not be so many soldiers willing to die with him at all.

In Yan Yan's lamentation, even he himself had lost the courage to go out of the customs, not to mention the other soldiers in the customs.

……

In the winter and October of the second year of Jian'an, at the beginning of the month, Fu Gan finally led his troops to Xindu County and successfully joined Jin Jue.

At this time, Fu Tong had also led 30,000 soldiers to successfully block Huang Quan in Niuluo County, like Gao Xiang, he used the same method to arrange a tight defense outside Niuzhuang City, Huang Quan saw it, looked at the four strong camps outside the city ditch and the city gate, and could only be the same as Yan Yan, who was in a hurry but couldn't do anything.
