After speaking, the palm of his hand was raised, and the archer on the city wall drew his bow and aimed at the cavalry in front, and a volley fired, ten thousand arrows came out, and the cavalry shield below was raised, blocking the rain of arrows, many cavalry fell to the ground, and the horses were injured.

Under the order to "withdraw", the cavalry retreated one mile.

Seeing the cavalry retreating, Huang Chengqi nodded with satisfaction, and said to the side successfully: You quickly get out of the city, go to the ten emperor brothers for help, and hand over a handwritten letter to the other party after speaking. Taking advantage of the retreat of the cavalry, he successfully rode out of the city and went straight to the mountains behind the city.

Yu Xiaofeng glanced at the rain of arrows inserted on the ground in front of the cavalry array, and said coldly: Assemble the trebuchet and prepare to attack the city.

50,000 cavalry, each horse dragged a trebuchet component, this is a small trebuchet newly developed by the imperial court, although it is not as powerful as the siege trebuchet, it can be matched with the newly developed fire bomb, the power is amazing.

"What are they doing" Huang Chengqi saw that the cavalry under the city began to dismount, and he didn't know what he was doing. Chengye shook his head and looked down, he couldn't figure out what these guys were doing. After a long time, the rows of trebuchets were assembled, and they looked very small, not much bigger than war horses, but a little less cold than the siege of the city.

"Trebuchet?" Huang Chengqi frowned, and when he saw the trebuchet in front of him, he laughed. What can such a small trebuchet throw, I'm afraid it can't even throw a fist-sized stone.

Chengye also shook his head, could it be that he followed Yu Xiaofeng, and the imperial cavalry was also stupid?

On the city wall, almost all the Lanzhou soldiers began to laugh, the pocket version of the trebuchet in front of them is really cute, which makes people like it a little, if you get one for your own doll, the doll will definitely love it.

In the laughter of everyone, the trebuchet finished loading for the first time, Yu Xiaofeng looked at the faintly audible laughter on the city wall, the corners of his mouth curled, and he yelled: Release.

Sou.. The ammunition ignited, the trebuchet suddenly launched, and one after another black fire bombs rose into the air, and they were hurriedly thrown into Lanzhou City in front of them. Cheng Ye saw the cannonball coming, but it was the size of a fist, he pulled out the saber on his waist, snorted coldly, and rose into the air, the big knife swept towards the cannonball, and the cannonball was actually made of paper, and it was cut in half in half in an instant.

"How good should I be" Chengye disdain. Before he could react, he heard a loud bang, and the fire bomb that he had cut into two sections exploded instantly, and the fuel inside suddenly turned into flames and erupted. The sea of fire instantly drowned the air.

"Ahh Chengye screamed and flew out upside down. As Chengye flies upside down, the fire rain falls from the sky, and there is a bang. It fell on the soldier, instantly igniting the soldier's armor, followed by a rain of fire bullets. The walls were like a sea of hellfire, screaming everywhere, flames everywhere. This is not the end, Chengye cut the first fire bomb, followed by the fire bomb like rain, falling into the city wall, the city. Each firebomb hit the ground and exploded in an instant, flying with countless flames, hitting everything that could burn, igniting it.

"Chengye" Huang Chengqi took off his coat and covered Chengye's body, the flame was extinguished, but Chengye was already burned and not human. Blood foam is constantly spurting from the mouth. looked at Huang Chengqi with difficulty, raised his palm and held Huang Chengqi's hand tightly and said: Master, Chengye is afraid that he will not be able to accompany you.

"Success." Huang Chengqi shook his head, held Chengye's palm tightly, and said with slightly red eyes: No! You're not going to die, you're not going to.

Chengye smiled lightly when he heard this, a mouthful of blood flowed out of the corners of his mouth, and he tried to speak: Promise the slave one thing, treat Sister Tianxue well, she is a person who is really good to you. After speaking, the palms of his hands gradually weakened, his eyes lost their agility, and blood flowed down the corners of his mouth, sprinkled on the cold city walls.

"No... Huang Chengqi was heartbroken, looked up to the sky and roared, looked sideways around, the sea of fire was splashing everywhere, and the surrounding soldiers were at a loss to fight the fire, or trying to extinguish the flames on their bodies, Lanzhou was finished!
