Night falls.

The imperial army had already collected its troops and returned to the camp, and the city was still brightly lit, and teams of soldiers patrolled back and forth, vigilantly watching the wind and grass outside the city.

There was no shortage of fuel in the county and it could be used unscrupulously, so the number of lanterns and torches on the city walls was exaggerated, and almost all corners were illuminated as bright as day, along with the important areas of the city, and there were special people patrolling the sides.

Intrigues and tricks are mostly brewed and implemented in a dark environment, and Zhao Yuanjin's style makes some people in the city very helpless, gritting their teeth and having a little envy, jealousy and hatred, after all, not all the princes of any family have the confidence to squander like this.

Due to backward productivity, the production of oil crops in ancient times was not high, and most of them came from animal fats and fats, or vegetable oils. Therefore, in the military field, oil is a very important strategic resource, which is limited in quantity and has always been relatively expensive.

Of course, Qin Feng has already understood that there is also "hot oil" produced in this world, that is, oil. It's just that most of them come from the Western Regions or the north, and the means of exploitation and utilization are primitive and backward, so the output is also very limited. This is similar to the world in which he lives, and there are records of the use of oil in the history books as early as the Western Zhou Dynasty, but on a smaller scale.

In an inn, the Songlin Daoist who had managed to blend into the city had changed his costume and seemed to be a scholar with a reputation for himself, so the shopkeeper was quite polite to him, and the men waited attentively.

In fact, this inn is a secret stronghold set up by the Jingcheng Division of the Imperial Court, which is dedicated to inquiring about news and supervising the situation in the city, but now Zhao Yuan is very vigilant, so the people here can not play much role now.

Due to the siege of the city by the imperial army for many days, a curfew has already been imposed in the city, and the common people are basically not allowed to go out after dark.

The sound of horses' hooves sounded through the streets, and a large group of soldiers escorted the long convoy in the direction of the city walls. The car was all covered with black cloth, and it was impossible to see what goods were being transported inside.

Songlin Daoren deliberately chose a room on the second floor facing the street, and stood behind the window lattice silently watching the convoy drift away. The throbbing and uneasiness in his heart became more and more obvious, as if the heavy clouds above his head were always lingering, bringing him indescribable heavy pressure.

Ever since he came to the imperial army camp, he had this feeling, and now it has been multiplied after entering the city.

The spiritual sense of a cultivator is far superior to that of ordinary people, and this kind of foreboding has brought him a very obvious warning sign. The best way to deal with this is to get out of the way immediately.

However, he is not alone, since the master has an order, those who are disciples can only obey. For the sake of Zhang Minxin's big plan and the long-term interests of the sect, there are some things he has to do.

"Do you want to sneak into the mansion of the envoy of the festival to have a look......

Songlin Daoren pondered, and immediately dispelled this thought. With the various incredible behaviors that Zhao Yuanjin's department has recently shown, there may not be no high-ranking people hiding in the mansion. After all, one's cultivation is limited, and once discovered, it is not ordinarily difficult to get out safely.

Judging from the current situation, Zhao Yuan is afraid that it is really possible to rise, and once the pattern of Jingzhou changes, it will be extremely unfavorable to the imperial court and the division.

Perhaps, it is still possible to solve the problem by truthfully reporting the matter to the master and sending a few elders with deeper cultivation to come over.

Early the next morning, the siege continued.

Yu Fangzhou, who had never recovered from his injuries, insisted on making a comeback and personally supervised the battle under the banner. Thousands of soldiers rushed to the city wall one after another, under the loud reprimand of the military judge.

The defenders of the city were in full array, and the dense arrows and stones fell in waves, and soldiers were constantly wounded and fell to the ground halfway. It didn't take long for the air to begin to fill the air with a strong smell of blood.

The commander of the capital, knowing that there was no way out, ordered the offensive to be intensified, and more soldiers with siege equipment stormed the city regardless of casualties.

From a distance, there was a crowd of people near the city wall, like a raging wave repeatedly impacting, hundreds of ladders were erected, and there were crashing cars below the city gate constantly impacting the city gate, and there was a tendency to die endlessly.

The pressure on the defenders on the city walls has increased, and the number of casualties has increased significantly, and once the imperial army commander is determined to fill it with a large number of lives, it is still entirely possible to capture the city.

At this moment, thousands of clay pots the size of human heads were suddenly thrown from the city wall, smashed to the ground and shattered, and a lot of viscous liquid flowed out, and soon a thin layer was formed on the ground.

"Is this ...... Kerosene? ”

In the chaos, some court officers quickly noticed this thing, and their faces couldn't help but change wildly, and they shouted a warning: "Withdraw, withdraw quickly!" ”

However, it was too late, and as a row of flaming rockets fell, a large area of fire rose from the ground, instantly enveloping a large number of imperial soldiers under the city walls.

In an instant, the offensive of the imperial army collapsed, the wailing and screaming of the city were endless, the air was filled with the smell of burnt human flesh, and a large group of soldiers who were on fire turned around and rushed towards the main formation.

Although the county town is surrounded by a moat, it is not a living water, and it has long been filled in by the sandbags and earth and stones of the imperial army in the siege of the past few days. Moreover, the fire caused by this oil is not easy to solve with water.

"Save ...... Help ......"

Hundreds of soldiers cried out in despair, and some fell to the ground as they ran, never to get up again.

The corners of Yu Fangzhou's eyes twitched, his face was as black as the bottom of a pot, and he roared ruthlessly: "Archers prepare, those who dare to approach this formation will be killed!" ”

Once these burning men were allowed to rush into the camp and cause even greater chaos, the consequences would be catastrophic. So even if he couldn't bear it in his heart, he could only give this cruel and cold-blooded order.

Hundreds of expressionless archers stood out in silence, arrows drawn from their bowstrings and flashing with metallic cold light aimed at the robes not far ahead.

When they rushed to a distance of dozens of paces, there were only more than 100 soldiers left alive, and they were immediately killed by the oncoming arrows.

As far as the eye can see, very few of the soldiers who participated in the siege of the city survived, and the corpses under the city were piled up, and a large area of flames was still burning freely.

The defenders of the city were constantly pouring oil on the siege equipment such as ladders, and then burning them to prevent them from being used by the imperial army again.

Yu Fangzhou looked around with a blank expression, only to see that the soldiers in this formation had a vague fear in their eyes, and the tragic situation under the city had an obvious deterrent effect.

"The spirit of the army has been lost, and the soldiers have no will to fight, so what can they ......"

The commander muttered to himself, only to feel a mouthful of blood rush up his throat, and he fainted as soon as it was dark in front of him.
