If only one of them is ignited, the others will be blown away by the impact it generates.
In that case, the power would not be enough to blow down the city wall.
Therefore, the only choice at the moment was to set up a fire under the city wall.
Only in this way can all the explosive packets be ignited at the same time.
Even if you can't ignite all of them at the same time, you can ignite most of them in an instant.
The only way is to use gunpowder to light a fire under the city wall and ignite all the explosive packets.
But this means that they must leave one person to light the fire for this plan to succeed.
But these are real people present.
They are all brothers who came out with me. Who will be left behind and who will not be left behind?
For a moment, Cheng Hualiang couldn't help but fall into a dilemma.
After all, this kind of thing is basically equivalent to asking him to kill someone.
And he killed his own brother.
At this moment, Cheng Huailiang raised his head and looked in the direction of Li Chengqian.
To be honest, he really wanted to go back and ask Li Chengqian what he should do now.
It must be said that Cheng Hualiang is still a bit younger this time.
There are always times when you have no idea on the battlefield.
But just when he was struggling, the Shu army had already boarded the city.
Obviously, because they were under the city wall, Li Chengqian had no way to direct the artillery troops to attack with all their strength.
After all, artillery fire has no eyesight and can easily hurt your own people.
After the Shu army defenders came up, they also launched an offensive directly towards them.
Many soldiers were unprepared and were hit by flying arrows and rolling logs and stones, and died on the spot.
And just when Cheng Huailiang was about to say that he would stay, Na Shichang, who had just come up with the idea, suddenly spoke.
He said directly: "General, let me stay." Hearing this, Cheng Hualiang was stunned.
Even if he reacts slowly, he still knows that this leader is prepared to sacrifice himself to protect everyone.
Without waiting for Cheng Huailiang to speak, Na Shichang continued: "I am an old man with no children, so I have nothing to worry about."
After saying that, he looked at the other brothers and said with a smile: "Brothers are still young and have to live."
After hearing this, the soldiers' faces were filled with sadness.
One of them said directly: "Chief, you'd better go back. This team can be without me, but it can't be without you. The brothers need you, so let me come."
"Come on."
"You still have a wife waiting for you at home."
"Do you have the heart to let someone make you a widow at such a young age?"
After Shi Changzhi scolded him, he said to Cheng Hualiang: "General, none of us men in Liangzhou are afraid of death."
"I'm not afraid of death either."
"Besides, it is my honor to die for justice."
As he said that, Na Shichang didn't care about the expressions of others, and then quickly went to look for the rolling logs that had been thrown from the city wall by the enemy.
Upon seeing this, Cheng Huailiang did not hesitate and quickly directed everyone to help search for flammable objects.
It didn't take long for the flammable materials accumulated under the city wall to become a small mountain.
At this time, the chief took down an explosive bag from the city wall, cut the bag open with a knife, and poured all the gunpowder inside onto the flammable material.
"General."
"Leave with the brothers."
The commander took a deep look at Cheng Huailiang, then opened his mouth and said: "It will be worth my while to follow His Highness."
Hearing this, Cheng Huailiang looked at him deeply and then asked, "What's your name?"
"Zhao Laosan!"
Zhao Laosan opened his mouth
Said something.
Cheng Huailiang nodded heavily.
"Brother Zhao..."
He said: "I will remember you."
After saying that, he resisted the urge to turn back and directly ordered: "Withdraw!"
Then, he led a group of soldiers and quickly ran towards the formation.
Along the way, arrows kept flying towards them, and the soldiers who had no time to dodge fell one after another.
Seeing this scene, Zhao Laosan looked straight at the city head and cursed angrily: "Traitor, I will kill your grandma!"
After cursing angrily, Zhao Laosan directly clashed the flints in his hands together.
Sparks suddenly shot out, instantly igniting the gunpowder on the ground...
You know, gunpowder has a very low ignition point.
Just one spark can create a fire that can reach the sky in an instant.
And this is why it is said that those who stay to light the fire will die.
The moment the gunpowder was ignited, a flame burst into the sky near Yizhou North City.
It was also at that moment that Zhao Laosan's figure was directly engulfed by the flames...
Boom! Boom! Boom!
A huge explosion was heard the next moment.
Dozens and hundreds of explosive packets exploded together, and the power produced was truly terrifying.
Not only the walls of Yizhou City were shaking, but also the ground on Li Chengqian's side was shaking.
Some unsuspecting soldiers were shaken by the sudden earthquake.
Of course, their side is still good, it's just wrestling at most.
But those Shu soldiers on the northern city wall were only a few centimeters away from the explosion point.
In an instant, the air wave generated by the explosion, accompanied by smoke and dust, submerged the entire northern city wall.
Fortunately, he was blown away by the air wave, causing his orifices to bleed.
If you are unlucky, you will simply be blown away by the air wave, until you fall off the city wall and become a pulp. And when the smoke and dust dissipated, everyone's eyes were fixed on the explosion point.
Even Li Chengqian clenched his fists tightly.
He was also afraid that the explosion would not have the effect he wanted.
However, in the end, he was overly worried.
The city wall of Yizhou City was also overwhelmed after this explosion, and a two-meter wide hole was blown out from top to bottom.
Seeing this scene, Changsun Chong, who had been waiting aside, did not hesitate.
He suddenly pulled out the saber from his waist and shouted straight ahead: "Brothers, follow me and kill!"
Immediately afterwards, he jumped on his horse and whipped his whip, taking the lead and rushing to the forefront of the battle formation.
And behind him were eight thousand Liangzhou tiger and wolf warriors.
Although they did not hear what happened under the city wall, they saw it with their own eyes.
The advantage in front of them was obtained by many brothers at the cost of their lives.
How could they fail their brothers?
In addition, today is already the sixteenth day of their siege.
In the war history of Liangzhou Army, there has never been such a long record.
At this moment, facing such an opportunity to break the city, who can not be excited? Who can not want to seize the opportunity to break the city and wash away one's own shame?
The soldiers of the Liangzhou Army value honor most.
Because every honor was earned by their ancestors with their lives.
What qualifications do they have to throw away the things that their ancestors exchanged for them?
How dare they disrespect their ancestors?
At that moment, the soldiers of Liangzhou Army also had red eyes.
Many people even used their two legs to run in front of Changsun Chong when sprinting.
When seeing such a scene, even Zhang Sun Chong couldn't help but be a little dumbfounded.
But soon, he reacted.
He raised his lips and shouted again: "Whoever enters the city first will be rewarded with two acres of farmland and one thousand and fifty dollars!"
