The people from the science and engineering department responded: "Mr. Hui, it's open!" ”

Xu Zizhen smiled: "Okay, lift the lid and show your face!" ”

"Yes!"

Zhao Gou and the others looked back, and they couldn't take their eyes off anymore, and everyone had their mouths open enough to stuff an egg.

I saw that there was a bunch of unknown things somewhere in the middle of the city wall, which was tightly covered with an oilcloth, and dozens of students from the Department of Science and Engineering didn't know what to do behind the oilcloth, but there was a burst of heat under the cloth, and with Xu Zizhen's order, several people stepped forward to remove a few large stones that pressed the oilcloth, and then lifted it hard, and a huge and strange thing appeared in front of everyone.

The appearance of the thing was dark and dreary, there was a fine iron shelf underneath, and on the top was a big round belly of iron bumps, which looked like a big wine jar resting on the stove, and there was a fire under the iron shelf, and a bellows on the left and right, and a dozen people were pulling both sides, and the flames were bulging red, and burned under the big iron belly.

This was not over, those science and engineering students took out thick and long iron rods from under the tarpaulin, and put them all together on the strange thing, and a dozen iron rods were assembled into a huge iron support, several feet long, and the tail end was resting impartially on the side of the city wall, and there was a big iron pocket on it.

When everyone was looking curious, they heard a few people from the science and engineering department say loudly: "Sir, everything is ready!" ”

Xu Zizhen waved his hand: "Okay, listen to my command, load up, and ignite!" ”

"Yes!"

Dozens of students shouted in unison, and dragged out a rattan basket from under the tarpaulin, the basket contained a ball, which was incomparably large, almost the size of two people hugging, and the surface looked black and shiny, I don't know what it was, dozens of people worked together to carry the big basket onto the big pocket on the iron support, and then took a torch to make up.

With a bang, the black ball suddenly ignited a raging fire, startling everyone.

Zhao Gou asked in surprise: "Zizhen, is this ...... What is it? ”

Xu Zizhen smiled: "You'll know in a while, see me scare and scare that grandson first." As he spoke, he raised the loudspeaker and said to the outside of the city, "Little Four, you are still running around with so many people in the cold weather, look at the birds that your sons and daughters are frozen, do you bring your own sweet potatoes?" I'll make a fire for you and roast you. ”

The smile on Wushu's face disappeared, he didn't know what a sweet potato was, but the fire word made him keenly aware of the slightest evil.

Xu Zizhen waved his hand and shouted: "Let's go!" ”

"Yes!"

The science and engineering students replied loudly, and the young man who was on duty at the head of the city just now stretched out his hand and pulled it hard at a certain place in the iron bracket, only to hear a crisp loud sound, the iron bracket bounced violently, and the fireball that was burning at the top of the bracket was thrown high and shot out of the city.

The fireball roared away with the sound of the wind, drawing a fiery red arc in the air, with billowing black smoke, like a star falling from the clouds, at this moment, both the Jin people and the Song people inside and outside the city were stunned, because they had never seen such a big fireball, and they had never seen such a big fireball fly so high and so far.

Wushu was probably one of the few people who was still awake, and when he saw the fireball flying out of the city, he immediately screamed badly, and shouted urgently: "After the order, the army disperses quickly!" ”

The junior colonel in charge of the military flag hurriedly raised the flag backwards, but it was too late.

Listening to a loud bang, the fireball fell impartially into the center of the Jin army, and burst violently at the moment of landing, exploding thousands of countless sparks, hundreds of soldiers and horses closest to the fireball landing site were all swept up by the strong air waves, and for a time the stumps and broken arms flew all over the sky, and the screams were endless, and the soldiers who were a little farther away were not necessarily better, because the small sparks scattered out of the body splashed and burned, the flames looked small, but they could not be extinguished, Even rolling on the ground immediately is useless.

The radius of a hundred meters where the fireball landed instantly became the hell of Shura, black smoke billowed to cover the sky and the sun, and the ground was full of charred corpses of people and horses, the miserable situation was unbearable, and those who survived and did not die were even more miserable, still rolling on the ground and wailing in mourning, until the scream became weaker and weaker, and then slowly died.

Wushu seems to be determined to conquer Ying Tianfu this time, so in addition to leaving a small number of soldiers and horses to guard Bianjing, almost all the left army was brought over, there are 100,000 horses, and he has always liked to suppress people with power, even if it is a long-distance attack, he likes to line up the army squarely, and it looks powerful, but in this way, it is good-looking, but the density between the soldiers and horses is greater, and the fireball smashed into the crowd, which caused him the most damage.

In addition, it is the middle of winter at the moment, and the armor on the Jin soldiers' bodies is lined with thick cotton jackets, the weather is dry and the wind is tight, and the flames spread immediately as soon as they get on their bodies, and they have burned up and down without even unloading their armor, and only one fireball has made the 100,000 Jin Army instantly fold more than 2,000 people.

The smile on Wushu's face that had always been on his face finally disappeared, and he stared at the city wall of Yingtianfu not far away, and almost burst out three words from between his teeth: "Xu!" Child! Frame! ”

Xu Zizhen didn't expect a fireball to cause such a big damage, he stared blankly at the charred land and corpses everywhere, and suddenly felt dazed in his heart.

It's not that he hasn't killed enemies since he came to this era, but he used to only use knives and guns, but he has never seen such a cruel scene as today, after all, he is a new human from the next generation, and for a while he can't accept that this scene is actually caused by himself.

There seemed to be a voice in his heart shouting: "These are thousands of human lives, human lives!" Xu Zizhen, you bastard, you are also a fucking murderer! ”

At this moment, a hand suddenly reached out from his side and patted him on the shoulder, and then, Zhao Gou's familiar voice sounded in his ears in a low voice: "If you don't kill the enemy, the enemy will kill me, don't be merciful." ”

Xu Zizhen was stunned, and looked back in amazement, only to see Zhao Gou looking at him with a smile on his face, his eyes full of encouragement.

To tell the truth, Xu Zizhen's heart suddenly rose up with the urge to beat Zhao Gou, thousands of living lives were gone, and he died so miserably, Zhao Gou actually hooked it with an understatement, and persuaded Xu Zizhen to continue to kill, although this is true from a certain point of view, but Xu Zizhen still felt disgusted.

But now, the turning point of an era is in the hands of him and Zhao Gou, and it is not time to turn around.

Xu Zizhen took a deep breath and forced a smile: "Don't worry, Seventh Master, I'm fine, I'm just stunned by that thing." After speaking, he turned his head to look out of the city, as if he was afraid that he would not be able to restrain himself in the next second.

After all, Wushu is a famous figure in history, he quickly adjusted his mood, calmness and confidence returned to his face, he turned his hand and pulled out his waist knife, and shouted: "Kulie'er, set up the formation, give me a siege!" ”
