Hard-hitting has always been a stupid choice, if there is enough time, Zhao Fan will definitely try to outwit Chang'an City, but the problem now is that time is running out, the remaining grain and grass of the Heavenly Mandate Army can last for another three days at most, and after three days, the soldiers can only fight hungry.

And the special status of Chang'an City made it impossible for Zhao Fan to use the tactics of fire attack or flooding, because Chang'an was not only the imperial capital of the Tang Dynasty, but also lived in millions of people, and those people were his people, so he could only choose to attack and forcibly enter Chang'an City from the front.

Now the Mandate of Heaven is using Joey's improved ladder, the bottom of the ladder is designed as a model with shields on all sides, and then the outside is reinforced with raw cowhide, and the personnel push the cart in the shed, which can effectively resist the stones and bows and arrows thrown by the enemy from the city wall, but it still cannot resist the burning of fire oil.

At the scene filled with gunsmoke, the soldiers of the Mandate of Heaven were not intimidated by the enemy, and were still attacking frantically, countless wells were pushed close to the city wall, and the archers above began to rain arrows frantically towards the city.

Not to be outdone, the defenders at the head of the city shot at each other with the Mandate of Heaven army on the well, and the stones and logs kept being thrown from the city, and the soldiers of the Mandate of Heaven attacking under the smashing were miserable.

For a time, Chang'an City became a huge meat grinder, people died every moment, there were Chang'an defenders, there were also soldiers of the Mandate of Heaven, everyone was equal in the face of war, everyone had only one life, extremely brilliant and extremely fragile.

With a loud noise, the trebuchet at the head of the city launched an attack, and a well was instantly shattered by the boulder flying out of the city, and the crossbowmen in the well were smashed into meat cakes at the first time, and the scene was miserable.

Countless boulders that did not hit the well fell into the ranks of the Heavenly Mandate army under the city, although they did not bring too many casualties, but they had a strong shocking power, after the boulders rolled over, only a messy scene remained, leaving countless stumps and broken arms, which made people awe-inspiring.

Under the threat of death, the soldiers of the Mandate of Heaven did not retreat, but relied on strong willpower to continue to attack.

Zhao Fan looked at the Heavenly Mandate Army with heavy casualties, and couldn't help frowning, although he had already been mentally prepared, but such a tragic battle situation was still beyond his imagination, at this moment he couldn't care about the integrity of Chang'an City, the city could be repaired again if it was broken, and if a person died, he would really die.

"General Zhao, pull the ballista out and shoot at the Chang'an city wall!"

"Yes!" Zhao Wei was a little puzzled and didn't understand what Zhao Fan wanted to do, but he still carried out the order without hesitation.

With Zhao Fan's order, hundreds of ballista carts were pushed out, aiming at the towering Chang'an city wall, behind each ballista stood a few big men, those big men were wearing single clothes, they seemed to be unaffected by the weather, put their hands on the keyboard of the ballista, and turned desperately.

"Put!"

Zhao Wei pulled out his long face, pointed at Chang'an City and roared, and then hundreds of crossbow carts fired arm-thick crossbow arrows in unison, hundreds of crossbow arrows passed through the heads of the soldiers, and they were nailed to the city wall.

"Keep it on!" Zhao Fan looked at the chaotic battlefield and said coldly.

"Keep firing the arrows!" Zhao Wei nodded and shouted loudly.

The rammed earth city wall, under the attack of the giant crossbow arrows, did not have any resistance at all, and the crossbow arrows with super penetrating power were not hindered in any way, and they pierced deeply into the wall, and in a few moments, a trace of spiderweb-like cracks appeared in the city wall.

"Tie the Sky Bombardment Thunder to the middle of the crossbow arrows, tie one crossbow arrow for every twenty Sky Bombardment Thunders, and then continue to shoot towards the city wall," Zhao Fan patted Zhao Wei's shoulder and said softly.

"The last general understands!" Zhao Wei's eyes lit up when he heard this, nodded frantically, and rushed towards the ballista's position with an excited face.

"Since there are no rocket launchers, let's try home-made rockets..."Zhao Fan looked at the hedgehog-like Chang'an City and muttered to himself.

With the industrial strength of the Luoyang Military Workshop, the Mandate of Heaven Army has now realized the mass production of the Thunderbolt, so when Zhang Ji came over this time, he brought a large number of Thunderbolts as a backup.

After all, his image of this thunderous thunder is too profound...

Luoyang production of thunder, not only strong in production, in the quality is more superior, Luoyang military workshop under the order of Zhao Fan, the gunpowder has been continuously improved, with the support of strong funds, everything is going very smoothly, now Luoyang military workshop produced black powder, the power has been almost the same as that of later generations.

Zhao Fan didn't think about studying other high explosives, but limited by the current scientific and technological situation, he could only give up in the end, after all, what picric acid and what nitroglycerin didn't have any concept at all in this era, let alone make it, fortunately, black powder was barely enough in this era.

Under the supervision of Zhao Wei, one by one the earthen rockets were successfully manufactured, one by one giant crossbow arrows, dozens of thunderbolts were tied in the middle, and all the fuses of the thunderbolts were tied together, and it is expected that after that, the fuses will be increased to a certain extent.

"Let's try to shoot first." Zhao Fan looked at the finished earthen rocket, nodded and said, "Be careful, this crossbow arrow is tied to so many thunderbolts, the flight path will change, don't blow up your own people." ”

"The last general understands!"

Zhao Wei was stunned, then understood, nodded fiercely and said, for a military general of his level, such a simple knowledge of physics is still understood, but Zhao Fan didn't mention it, he really couldn't remember, if he still aimed at the launch just now, it would have blown up his own people.

Thinking of this, Zhao Wei couldn't help wiping his cold sweat, glanced at Zhao Fan with some admiration, and secretly said in his heart that His Majesty was thoughtful, otherwise something would happen.

"You, shoot at too high an angle and use the projectile to aim at the wall ahead." Zhao Wei patted a strong man's shoulder and said with a frown.

"Yes!" The strong man didn't say much, just gently shook a shaking hand next to the ballista, and under the gaze of everyone, the arrow of the ballista slowly raised.

Fortunately, when Joey and Liu Menghan were improving this ballista, they had already thought that this ballista might be used for projectiles, so they designed this lifting device, otherwise everyone would have to use manpower to lift the ballista now.

"Shoot the arrows!"

With Zhao Wei's order, a strong man hammered the trigger fiercely, and the crossbow arrow instantly flew towards Chang'an City with a whistling sound of breaking the air, and under the gaze of everyone, it leisurely crossed the city wall and fell into Chang'an City.

"Oops, shoot crooked."
