It has been more than a month since the siege of Jingcheng, the food of the Liao army has long been eaten, and they have to rely on killing horses to satisfy their hunger, and the continuous high-intensity attack has also caused the Liao army to suffer extremely heavy casualties, and the 120,000 troops trapped in Jingcheng are less than 80,000 left, too many bones accumulate and the spread of animals, the most terrifying demon of the army is finally out of the cage, and an unknown plague spreads rapidly in the Liao army.

The combat effectiveness of the Liao army was rapidly weakened, and the continuous high-intensity attacks were also forced to stop, and at this time, the Song army also discovered the abnormality of the Liao State.

Di Qing, the commander of the Song army, issued five emergency orders.

First, soldiers with fever, vomiting and diarrhoea should be isolated immediately.

Second, all Song soldiers must take Tiezhou to go to Yansan every day.

Third, it is not allowed to touch the animals in the well, and it is not allowed to drink raw water, which must be boiled before drinking.

Fourth, it is forbidden to touch the corpses of the enemy, and after the battle, the corpses and mountain roads are to be burned with fire oil, and the roads and latrines are covered with quicklime.

Fifth, it is forbidden to accept any form of surrender from Liao soldiers, and any Liao soldiers who approach the pass must be shot immediately.

At this time, everyone knew about the outbreak of the plague within the Liao army, and the nature of the war began to change, from initially not allowing the Liao army to break through and flee to not allowing the plague soldiers to leave the valley.

Before dawn, the defenders of the lady noticed the abnormal movement on the mountain road, and a group of more than 1,000 Liao soldiers walked towards the pass with a white flag.

The main general Cao Wenjing got the news and immediately rushed to Guancheng, he looked at the mountain road with a monocular, only to see three or four hundred steps away, a large group of faltering Liao soldiers holding white flags, and they were weakly walking towards the pass step by step, one by one with dull eyes and a sickly face.

"Dog's day, let the patient surrender!"

Cao Wenjing gritted his teeth with hatred, he saw very clearly, these surrendered soldiers were clearly infected people, and it was obvious that the Liao army wanted the Song army to be infected with the plague and was unable to defend the pass.

"Stop them with fire oil!"

Dozens of large pots of fire oil smashed down the city, the clay pot was broken, the black oil was gathered on the ground, and slowly flowed to the bottom of the mountain road, when the enemy army was still two hundred steps away from the city, Cao Wenjing shot a rocket with his own hands, and a fire suddenly ignited on the mountain road.

The soldiers continued to smash the fire oil into the city, the raging fire blocked the way forward for the surrendered soldiers, and continued to spread, the surrendered Liao soldiers were frightened and retreated, at this time, hundreds of rolling wood and stones hit head-on, hundreds of soldiers dodged in no hurry, were hit by the rolling wood, fell directly in the flames, and were quickly engulfed in the flames.

The other soldiers were scared. They stumbled and fled down the mountain, but before they could escape to the bottom of the mountain, the soldiers below fired a volley of arrows, killing all the remaining hundreds of sick soldiers on the mountain path.

It was also Yelu Na who was also under the Niangzi Pass, and he was extremely depressed when he saw that his strategy of leading the water to the east had failed.

Forty percent of the soldiers have been infected by the severe epidemic, including his lieutenant general Yelu Hulu, who has died of tens of thousands of people, and more than 20,000 people who have no cure and are dying of illness.

No one knew how the plague broke out, and many soldiers speculated that the plague contracted the fallen soldiers when the beast bit the corpse, and then the beast was hunted by the soldiers as food, and the plague began to appear.

There are still 70,000 troops left in the 120,000 army under the command of Yelunaye, and more than 23,000 people in these 70,000 troops have broken out of the epidemic, and the remaining 40,000 people do not know whether they are infected or not, and they are divided into ten battalions and stationed in the mountain road more than 70 miles long.

Every day, the news of the illness of a new person came, and the entire Liao army was already extremely panicked, once someone fell ill, he was immediately driven out of the barracks, his belongings were burned, and he was driven out of the barracks without food and medicine, and it could only be a dead end.

Therefore, many soldiers are already seriously unwell, and they are desperately trying to hide it, lest they be driven out, and as a result, more people will be infected, and a vicious circle has been formed.

Yelu Na didn't know what to do, and he knew very well in his heart that once Yelu Hongji learned of the outbreak of the plague among the Jingcheng soldiers, he would not send anyone to rescue him.

"King, the plague is raging here in Niangzi Pass, if you stay any longer, sooner or later the whole army will be wiped out, so it's better to go to Jingcheng Pass!" More than a dozen generals asked him one after another.

Yeluna also glanced at the high fortress on the mountain, so he had to let out a long sigh and ordered: "Bring the deputy general, and the other sick soldiers will stay here!" ”

In the end, Jeruna made an unacceptably cruel decision, abandoning 23,000 sick soldiers, taking Yeluhulu in a carriage, and leading the army to the east.

In a narrow valley, more than 23,000 sick soldiers were isolated here, without a military doctor or medicine, and the dead soldiers could not deal with it, and were thrown into a large pit, and the stench and smell of death filled the canyon.

Many people wanted to break out of this valley of death, but the mouth of the valley was blocked by heavy troops, and if they came close to the valley, they would be shot by arrows, and hundreds of dead horses would be thrown in every day to feed them.

All the soldiers were desperate and sat scattered in the canyon waiting to die.

In the afternoon of that day, dozens of sick soldiers unexpectedly found that the soldiers guarding the valley had disappeared, and they slowly walked out of the valley, only to find that the Liao troops outside the valley were gone.

"They left us behind!"

Dozens of soldiers rushed back into the valley, shouting, the news spread quickly, the main army abandoned them and retreated eastward, fear and anger made the soldiers completely explode, and the instinct to survive made tens of thousands of Liao soldiers who were slightly less ill desperate to chase after the main force.

In the night, dozens of bonfires were lit in an open space in Jingcheng, around which more than 40,000 soldiers ate horse meat and drank soup.

Jeruna also stood up and said angrily, "What happened? ”

A soldier ran to inquire, and after a while, he rushed back in a panic and said, "King Qiqi, tens of thousands of sick soldiers have caught up." ”

Yeluna was also stunned, and he suddenly turned around and glared at a general, "How did you arrange it?" ”

The general was also at a loss, and hurriedly explained: "I left three hundred people to guard the valley mouth, but I don't know why I didn't hold it?" ”

Jeruna was also furious, "Bastard! Now that it's messed up, what should we do? ”

The confusion that Jeluna also refers to is that the sick soldier mixes in and infects other soldiers.

The generals knew what to do? They looked at Jerunaya together, waiting for his decision.

Yeluna also gritted his teeth and said: "I don't want to kill each other, since they don't know whether they live or die, then don't blame me for being ruthless." ”

He immediately ordered: "Anyone who disturbs the army without permission can be killed on the spot!" ”

Several generals were taken aback, and hurriedly persuaded: "It's better to gather them first, the killing will be even more chaotic now!" ”

Yeluna also shook his head, "They won't be fooled again, take advantage of the fact that they haven't mixed into the army now, isolate them, and kill as many as they want!" ”

Jerona also no longer concealed it, and immediately sent an order, "All the sick soldiers are isolated, and those who do not obey will be put to death!" ”

In fact, the situation is out of control, and the soldiers who have experienced the fear of isolation in Death Valley do not want to be quarantined again, and none of them are willing to obey orders, and they are desperate to get into the ranks of normal soldiers, causing fear among normal soldiers, who are afraid of being infected with the epidemic, and they have poisoned their former comrades.

And the commander's order made the frightened normal soldiers of the Liao army no longer taboo, and went on a killing spree, in their eyes, these soldiers infected with the epidemic were no longer their companions, but possessed by demons, and they began to ruthlessly slash and kill the sick soldiers.

And tens of thousands of sick soldiers were originally seeking a way to live, but they were killed, their anger was difficult to suppress, and then broke out, they roared and snatched weapons and normal soldiers to fight, a serious internal strife appeared in the Liao army, the night could not see the other side clearly, the panic made all the Liao soldiers lose their minds, regardless of the indiscriminate slashing and killing of each other, there was chaos on the Jingcheng Road.

The day gradually brightened, the exhausted Liao army finally calmed down, there was a bloody storm on the Jingcheng Road, more than 20,000 people died in the internal strife, and countless people were injured, and the armor of the remaining more than 30,000 soldiers was stained red with blood, and it was no longer clear who was a sick soldier and who was a normal soldier.

Jeruna was also covered in blood, and he felt that he had also been infected by the plague, and only half of the dozen generals remained, and the other generals died in the chaos.

Yeluna was also desperate in his heart, and he had no choice but to send a few soldiers with his own handwritten letter to Jingcheng Pass to ask the Song army to surrender.
