"Fourth brother, you are... Before Xiao Shan's words could be finished, he saw a few loud bangs in the moat of Qinguan, and then ten huge whirlpools appeared, swallowing the entire river like a big mouth. Within a moment, the moat, which was still burning violently, had dried up, and ten huge holes in the riverbed were clearly visible.

"Hey, hey, little meaning. "It turned out that Xiao Yu used the same move he used to deal with Wu Lingfeng to lead the river water into the big pit created by the Earth Trapping Technique, but it was the lake water that was sucked at the beginning, and this time it was indeed the burning moat water.

"Nima! What kind of tricks does this kid have! The whole army is on alert, ready to deal with the opponent's strong attack!" Seeing the scene in front of him, the city head guard scolded secretly, but he didn't expect that the river of flames he had worked so hard to create would be broken by this stinky hairy boy, and it was even broken so completely.

The defenders of the city who had received the order became nervous one by one, and stood behind the female wall with bows and arrows, all on guard. However, the Yingzhou Army did not make the slightest movement at the moment, just as Xiao Yu broke this moat and was completely unattractive to them.

In fact, it was not that Xiao Shan didn't want to attack the city with this, but that Xiao Yu strongly asked him to stay still.

"Fourth brother, tell me, why don't you let me attack the city. Xiao Shan looked at Xiao Yudao suspiciously.

"Brother, although this moat has been dried up, who knows how much fierce fire oil is still waiting for us in the city, you forgot, the spies said that the ravine behind this Qin Pass is produced in the fierce fire oil. ”

"That... So when can we attack the city, we can't just waste it with this just because the other party has a lot of guys. ”

"Don't worry, wait for the evening, let's bring him a bowl of fierce medicine to taste when the time comes." Hey. ”

Looking at Xiao Yu's smiling expression, Xiao Shan was also puzzled for a while, but after thinking about it, since Xiao Yu has a way, why do you have to go up and fight hard now.

。。。

At night, a little light gradually went out in the originally brightly lit military camp, and a team of Yingzhou soldiers with longbows followed Xiao Yu at night, sneaked out, and climbed a high mountain on the south side of Qinguan City by night.

No one dared to say a word along the way, and more than a thousand archers selected from various archery battalions held their breath like this, followed Xiao Yu quietly to the top of the mountain, and took in the situation on the wall of Qinguan under the mountain.

"See that black vat over there, show me that shot, as long as one of the more than 1,000 people hits, we won't come in vain this time." Xiao Yu whispered to his archers.

To say that Xiao Yu is also lucky, originally in order to prevent the defenders of the Yingzhou Army attacking the city late at night, one by one they held torches to brighten up the entire city wall, and the only place where there was no fire was the location of the huge vat, Xiao Yu thought that it must be the place where the fierce fire oil was stored, after all, who would dare to play with fire next to this thing, if it fell into a little spark, wouldn't something happen.

"Everyone prepare the fire fold, light the thunder arrow, and shoot it at me in that vat!"

"Ready!" As soon as Xiao Yu gave the order, the archers all over the mountains ignited the fire fold and raised it in their hands to prepare to light the fire.

And the sudden fire on the hill also attracted the attention of the defenders of the city wall.

"General, look, there are people on the mountain!"

The guard looked up, only to see the flickering fire at the top of the mountain looming, and even saw a lot of figures shaking through the bright light, presumably the Yingzhou army was preparing to attack Qin Pass at night.

"Herald, beat the drum three times to call all the troops in the camp to me, prepare to prevent a sneak attack by the enemy!"

Before he finished speaking, Xiao Yu gave another order.

"Ignition!" More than 1,000 archers lit the thunder arrows in their hands in unison, and the long fuse instantly burst into flames, and a cloud of green smoke came out with a loud sound.

"Put!" Xiao Yu knew very well how long the fuse of the Thunder Arrow he had developed, and he didn't dare to delay for a minute or a second at the moment, so he immediately ordered a group of archers to bend their bows and shoot arrows.

In an instant, more than a thousand flaming arrows shot straight at the defenders of the city with the sound of breaking the wind that tore through the sky.

"Quick, raise your shield to defend yourself, and protect me with the fierce fire oil. As soon as the guard saw that the arrows were flashing with fire, he immediately guessed Xiao Yu's intentions, and hurriedly ordered the infantry at the head of the city to use shields to protect the fierce fire cylinders.

It's a pity that he didn't know that the arrows shot from the top of the mountain were not ordinary rockets, but thunderbolts with a lot of black powder.

"Boom, boom, boom. ”

For a moment, the explosion on the top of the city tower was deafening, and the city walls began to tremble. More than 1,000 thunderbolts fell straight near the fierce fire oil tank, and the infantry who were still holding shields to defend were instantly blown into pieces, and at this moment, the fierce fire oil in the tank was also ignited, and the raging fire burned directly from the city, and the fire was thick with smoke, and the city head was in chaos for a moment.

"What is this... What is it... The guard was also stunned by the earth-shattering explosion, watching his soldiers suffer countless casualties, and the fierce fire oil that he relied on turned into a sea of fire, he opened his eyes wide at the moment.

"General, let's organize a firefight. Fortunately, the lieutenant general reminded him in time to wake up the nightmare-like guard.

"Quick, extinguish the fire quickly, press it with a steel plate. He knew that as long as the fierce fire oil burned, it was impossible to extinguish it with water, and it could only be extinguished by compacting it with steel plates.

However, he thought it well, but unfortunately Xiao Yu didn't give him a chance to do so.

In the blink of an eye, the second batch of thunderbolts roared, blowing up the soldiers who were carrying the steel plates and preparing to extinguish the fire, and even the huge steel plates were lifted out and fell straight under the city wall.

And the bad luck of the defenders is not over here, I don't know which archer, the arrow actually hit the base of the vat, the violent explosion power actually lifted the big copper vat, I don't know how much fierce fire oil was poured into the city in an instant, swallowing the military camp under the city wall into the raging fire.

"Quick! put out the fire with dirt! Originally, the current city wall was already in chaos, and the guards did not expect that the barracks under the city were also ignited, and countless defender soldiers were on fire all over their bodies, rushing out of the camp, trying to find a life-saving straw to keep themselves alive, but unfortunately the reality is always crueler than dreams, and the guards watched their soldiers under him being burned to charcoal one by one, and fell to the ground motionless.

"Damn, fight, I can't be treated as a live target like this anymore, and the one who is still panting is counted as one, kill with me, even if I die, I will die on the battlefield, I can't be so aggrieved and burned into black charcoal!" The guard general is also fighting, he knows that if he continues like this, he will die, and Qin Pass will be lost, so it is better to take the troops out and fight with the Yingzhou army.
