Chapter 1898: The brutal attack and defense of Yanjing (9)
Boom...boom...boom...
Flying rocks and kerosene continued to fall, but because the Qin army's catapults were scattered, only a small part was damaged.
As for the fire oil dropped by the Han army, groups of five or six Qin soldiers quickly extinguished it with sand and earth, one by one.
"ah……"
The unlucky soldiers were affected by the kerosene and their bodies were ignited by flames, but they could not put them out and could only roll on the ground in pain.
When the comrades around saw it, they immediately poured the sand and soil from their backs directly onto the soldiers, and also used the sand and soil to extinguish the fire.
After paying the price of twenty catapults being destroyed, the Han army on the tower also fell within the siege range of the Qin army's catapults.
Seeing this, Xue Rengui made a decisive decision and shouted: "Throw fierce fire oil."
The soldiers immediately loaded the catapult and loaded jars of burning oil onto the catapult.
One hundred and eighty catapults, each projecting three jars of fierce fire oil, one round is 540 jars.
Boom...boom...boom...
Five hundred and forty altars of fierce fire oil fell on the city tower, and in an instant, one-twentieth of the city tower was tilted back.
Many Han army defenders were burned to ashes. Unable to bear the pain, they jumped from the tower, preferring to fall to death rather than be burned to death.
As for the other defenders, under the command of North Gate Guard Su Jian, they also used various means to put out the fire.
However, the Qin army's fierce fire oil was different from the Han army's fire oil. It was not only more powerful, but also more durable and difficult to extinguish.
The Qin army's fire oil is a new type of fire oil extracted from petroleum. Once ignited, it will burn everything around it before burning out. It is not easy to extinguish it even with sand and soil.
Qin Hao naturally had no hope for the powerful weapon of oil. He had no idea how to dig underground oil, but open-pit oil could still be collected.
After searching for two full years, Heibingtai's spies finally found two oil fields in Nanyang and Hanjiang.
Qin Hao immediately ordered the oil field to be sealed and built a kerosene processing plant on the spot. He urgently processed and produced kerosene. It took him a year to refine 100,000 jars of kerosene, which was barely enough for the Qin army to consume.
When attacking Jizhou, relying on this new type of fierce fire oil, the Qin army succeeded in attacking the city many times, and the Korean and Zhao coalition forces screamed in agony.
The output of the two kerosene plants in Nanyang and Hanjiang alone cannot supply the entire Qin army for continuous consumption, but only these two places have oil fields under the Qin army.
It is strange to say that the Qin army surrounded the four prefectures of Bing, Yong, Jing, and He, but only Jingzhou had two oil fields. The huge Bingzhou and Sizhou did not even have one.
In the process of attacking Jizhou, more than half of the new fierce fire oil had been consumed. Jingzhou was also attacked by Shu and Chu, and Sizhou was attacked by Tang. The situation was critical.
Therefore, the production capacity of Hanjiang Oilfield can only be supplied to Jingzhou first, while Nanyang Oilfield must also be supplied to Sizhou first, so that the Qin Army in Hebei is about to face the situation of running out of kerosene.
Fortunately, there is always a road ahead.
Just when the new fierce fire oil was about to be exhausted and could not be replenished, Gu Yong, the Bohai governor appointed by Qin Hao, discovered an oil field in Bohai County. Its production capacity could not supply Hebei's hundreds of thousands of troops, but he could save a little
It's still barely enough.
With the supply from the Bohai oil fields, the Qin army could use the new type of fierce oil when they attacked Youzhou.
The Qin army's new type of fierce fire oil is extremely difficult to extinguish. This is the experience summed up by the Han army with blood and lives in constant defeats. It also found an easy way to extinguish it.
Whenever the fire oil is poured with water, it will become more and more watery. It can only be extinguished with sand and soil. Although sand and soil can also extinguish the Qin army's fierce fire oil, the effect is not very good and it must take a certain amount of time.
In a siege battle, every second is precious, and every position on the city tower is extremely important. If it takes so long to put out the fire, there will be no need to defend the city.
In the constant defeats, the Han army actually found a way to quickly extinguish the fierce fire.
This method was thought up by Wei Qing, which is to add a certain amount of gravel to the sand and soil, so that the violent fire oil can be quickly extinguished.
Liu Che had long expected that the Qin army would use heavy fire oil to attack the city, so he prepared 200,000 sacks of sand, gravel and soil in Yanjing City in advance. The only purpose was to extinguish the fire. If it was not enough, it could be used on the spot in the city.
Made from materials.
All in all, as soon as the Qin army's catapults approached and the heavy fire oil had not yet been thrown on the city, Su Jian was already ready to put out the fire.
As soon as the fire broke out, Su Jian's soldiers who were specialized in putting out fires, carrying generations of sand, gravel and soil, extinguished a large area of kerosene. However, the next wave of kerosene was thrown up again, and the Han army defenders could only
Continue to put out the fire.
Xue Rengui let the catapult launch ten rounds, and after firing out 5,400 jars of fierce fire oil, he stopped consuming the fierce fire oil and switched to flying stones.
It is impossible not to stop. After all, the one side Xue Rengui attacked was 5,400 altars, and the three sides were 16,300 altars. The Qin army could not afford to consume such a force.
Under the Qin Army's 5,400-tank fierce offensive, the Han Army lost a large number of catapults and crossbows, and thousands of soldiers were burned alive. But similarly, the situation on the Qin Army's side was not much better.
The Qin army also had to face the Han army's fire oil, rockets, and flying stones. Compared with the Han army defending the city, the Qin army on the attacking side obviously suffered greater losses.
Under the Han army's offensive, the Qin army lost nearly one-third of its catapults, only twenty of its fifty wells, and its soldiers died in battle.
This is not only true for Xue Rengui, but also for the other two city gates. It can be said that the two sides are competing against each other.
Since the moat of Yanjing has not been filled in, Xue Rengui did not let the soldiers attack the city directly. Instead, he first used catapults and crossbows to shoot at each other with the Han troops on the towers, and at the same time asked the soldiers to carry sandbags back and forth to fill in the moat.
.
The biggest advantage of doing this is that it can reduce casualties, but the disadvantage is that the siege equipment is seriously damaged and the supplies are consumed too fast, but the Qin army is obviously not afraid of this.
With the capture of Yuyang and Shanggu counties, the Qin army can transport supplies through these two routes. As long as the consumption rate is controlled within a reasonable range, there will never be a problem of running out of supplies.
"General, the losses have been too great. In less than an hour, our army has killed thousands of brothers, but the Qin army's offensive has not weakened at all,"
"Quick, go tell the commander that the Qin army's offensive is too fierce and our army needs support."
Su Jian said anxiously to the soldiers around him, but he didn't realize that his body was exposed outside the city wall.
Outside the city, on a well fence, Xue Rengui held a long bow, looked coldly at Su Jian on the city tower, and said coldly: "Knowing that the opponent is me, Xue Rengui, and dare to show your face, you are simply looking for death."
After saying this, Xue Rengui loosened his bow string and shot out the iron arrow in his hand. The target was Su Jian on the tower.
[Ding dong, Xue Rengui’s skill ‘Arrow God’ is activated, instant force 6, basic force 105, equipment 2, current force increased to 113.]
"General, be careful..."
Su Jian, who heard the reminder, was about to squat down when the iron arrow was already coming directly in front of him, and he had no time to avoid it.
Snapped……
Su Jian's head was exploded by an arrow, leaving only his body, which fell directly to the ground.
In this way, the Qin army had only been attacking the city for an hour, and Su Jian, the guard at the north gate of Yanjing, died tragically under Xue Rengui's arrow.
