Gongsun Zhan's Chinese army camp was built on a high slope outside the north gate of Bohai City, and he could have an overview of the overall situation from a high vantage point, because Gongsun Zhan was not worried about the defenders in Bohai City going out of the city to rob the camp, so the military camp was so close to Bohai City.

"How's the siege going?" Although Gongsun Chan was sitting upright, there was still anxiety on his face.

A small general arched his hand and said: "The north gate, the east gate, and the west gate have suffered heavy losses, and thousands of soldiers have been broken, and the ditch can be filled in less than half an hour outside the north gate, and the archers in Bohai City have shot secretly, and the arrows are raining down, which greatly reduces the morale of our army." ”

"Secret method?" Gongsun Zan had mixed feelings in his heart, when he fell for Guo Fengxiao's plan under the Tiger Prison, Liu Bei reminded him that he didn't believe it, and he woke up after the war, and also noticed Guo Fengxiao under Yuan Shao's account.

Seeking to take four states, the tiger prison agitated generals, Yuan Ying's three plans, the head of the family, taking Jizhou, Boyi's name, defeated Xu Rong, Bohai City has stepped to conquer the horse, leading the soldiers and civilians in Bohai City to scare away the 20,000 light cavalry under his command, such a genius, Wen Taowu is the best in the world.

"Guo Fengxiao's talent can be worth 100,000 elite soldiers, half of Jizhou, if it can be used by me, why worry about hegemony?" Gongsun Chan sighed in his heart.

Gongsun Chan raised his head and asked, "Is there a tendency for the defenders in the city to be defeated and retreat?" ”

The young general replied with a look of hesitation on his face, and replied ashamedly: "There is no sign of defeat and retreat, our army will lose thousands of soldiers when attacking the city, and the morale of the enemy army will be greatly shaken, and the momentum will be like a rainbow." ”

Gongsun Chan is clear,**a**book**read. The novel ybdu his vanguard was defeated, and the soldiers under his command were in turmoil, if they did not break through Bohai City in one go, I am afraid that there would be no hope of breaking the city in the future.

"The herald is single, outside the north gate to storm Bohai City, if the defenders do not flee, act according to the plan." Gongsun Chan said again.

"The last general commands." The young general withdrew from the Chinese army's tent.

After seeing the more than 1,000 soldiers gathered next to him, and then looking at the ravine under Bohai City, which was almost filled with the corpses of soldiers, he made up his mind to wait for the ravine to calm down, and he would break through the north gate with all his might!

Guo Jia watched the changes and saw that Shan Jing was boosting the morale of the soldiers beside him, Guo Jia guessed that the more than 1,000 people should be the first to die.

These dead soldiers are like rainbows, with a farewell look on their faces, and they must fight to the death.

Guo Jia looked at the ravine under the city again, and it would be filled by Gongsun Zhan's army in a few moments, and the siege vehicles and siege towers behind the ravines were ready to move, and they had already prepared to go.

"What about the other three?" Guo Jia asked.

"Shooting thousands of enemy soldiers, morale is shocked, and the other three gates can hold on for a few hours, only my north gate is in a hurry."

A moment later, the only barrier gully outside the north gate had been filled in by Gongsun Zhan's army.

He ordered all the generals to attack the city with siege equipment, and ordered his archers to step forward and release arrows to suppress the archers on the city wall, and the siege vehicles followed.

The enemy's vanguard retreated, replaced with thousands of sword and shield soldiers, relying on siege vehicles and siege towers to march according to the shield, the enemy shouted in unison, the momentum was like a rainbow of battle spirit, and there was quite a determination to break through Bohai City.

Just now, the soldiers in Bohai still had to go to the enemy army to fight to the death, and at this moment the soldiers became nervous when they approached the city, and they were still afraid of death in their hearts, and they were even more afraid of the 100,000 troops outside Bohai City.

"Xiansi, ancient wars, uh, cough cough, from ancient times to the present, whether it is a siege or a field battle, has plotted the winner, mostly for the fire attack, followed by water, for the general should be through astronomy, know the location, know the strange door, know the yin and yang, understand the formation, the Ming troops, the party has been in harmony, has been a strange victory." Guo Jiadao.

Yuan Tan kept it in mind, and he was a little curious about why Guo Jia didn't give him an example this time, so that he could understand this knowledge more quickly.

In fact, Guo Jia also wanted to say, but he really couldn't give a good example, so he couldn't tell Yuan Shao that the three major battles in the Three Kingdoms period were all won by fire, right?

The fire of the Battle of Guandu burned the Wuchao, the fire of the Battle of Chibi burned the ship, and the fire of the Battle of Yiling burned the company camp, this is the fire.

Guan Yu's pinnacle of the earthquake in China flooded the Seventh Army, and in history, Guo Jia's siege of the city captured Lu Bu, which was water.

Regardless of fire attack, water attack needs to reach the sky, if the fire attack is simpler, you need to know that the climate is humid and the wind direction changes.

If you attack with water, it is much more difficult, and you need to be proficient in the right time and place, and you need a once-in-a-lifetime opportunity.

Guo Jia said: "If it is to defend the city, it is easier to attack with fire, the enemy's siege equipment is wooden, although it is wrapped in iron sheets, it cannot prevent the fire, if it has been attacked, it can break the enemy's siege equipment." ”

Yuan Tan suddenly realized and said, "The student understands, the master prepared the fire oil in order to destroy the enemy's siege equipment. ”

Guo Jia smiled faintly and said, "All the soldiers are quietly guarding, waiting for the enemy's siege equipment to throw fire oil cans fifty paces away from the outside of the city." ”

Guo Jia had already prepared, gathered the fire oil of the whole city, put it into a clay pot, the mouth of the pot was sealed, the clay pot was fragile, and it would be broken if thrown from the city, and the fire oil splashed in all directions, just ignite.

He also gathered the strong men of the city, and prepared to order them to throw the canisters of fire oil together, and now only wait for the enemy's siege equipment to approach.

Shan Jing was a little puzzled, why did the Bohai defenders not fight back with archers, but cowered on the city wall, saying that this moment was the best opportunity to attack the soldiers under his command, is there no bow and arrow?

Impossible, just didn't believe that Guo Jia would do such a stupid thing, he believed that Guo Jia had a conspiracy, but he couldn't think of any conspiracy for a while.

"The first to board the dead has stepped forward, and the ladder has attacked!" After a single whip and a general order, he wanted to test the reality of Bohai City first, and he was a little scared by Guo Jia.

"The big shield man stepped forward, and his shield was against the wall battlement, and the pikemen followed closely behind, attacking and killing the rats under the city!" Guo Jia saw that the enemy had already charged down the city with a shield and a ladder, and quickly ordered the soldiers on the wall to deal with the enemy.

He had previously trained these soldiers and civilians how to defend the city, and the stronger ones raised large shields, and two pikemen were placed beside them, and the enemy soldiers could use a large shield to hit the ladder, and if they could not knock the ladder away, they could also use the large shield to shoot away the enemy troops who climbed to the top of the ladder.

Although the enemy army is brave, the Bohai defenders have the advantage of the terrain, and they have been fighting for a few moments, and they have not let the enemy soldiers climb the city, which is naturally related to Guo Jiana's keen insight and every just right increase in troops.

When the enemy siege vehicle arrived, Guo Jia smiled faintly, and endured it for so long for this fatal blow.

"Bow and arrow!" As soon as Guo Jia waved his hand, Wang Dali handed over a soft bow with Huadiao and a rocket waiting to be ignited.

"Throw the oil tank!" Guo Jia gave an order, and hundreds of powerful soldiers and civilians on the city wall raised the canisters in their hands and smashed them into those siege vehicles and siege towers.

The sound of crackling and cracking is endless!

"Yes, yes, it's oil!" The enemy troops in the city were shocked when they found out that the splattered clay pots were kerosene oil, because they had already thought about what would happen to them.

Wang vigorously lit the fire, Guo Jia raised his bow, and suddenly a pride rose in his heart, and his left hand was gently loosened.

Flags and arrows wrapped in strips of cloth whizzed towards the siege engines stained with fire oil!

"Archer, put!" Guo Jia gave another order, and the archers who had been cowering on the city wall responded to the call.

Guo Jia lowered his head and sneered, he thought of a sentence, an arrow piercing the clouds, a sea of arrows and a sea of fire to meet!
