The thunder exploded, and the earth seemed to be shaken, followed by a few muffled thunders, lightning flashed through the dark clouds in the sky, and then a drop of raindrops the size of beans fell to the ground and shattered into several petals.

Syllable! Smack!

The heavy rain poured down in an instant, and the heaven and earth were suddenly covered by a thick curtain of water that made it difficult to see far away, but there was a gloomy smile on his sticky face, he didn't care at all that he was soaked in the rain, and waved his right hand forward, and the herald beside him understood and shouted: "Herald, attack the city with all your might!" ”

"Siege the city with all your might!"

"Siege the city with all your might!"

The drums of war began to sound again, dense and low, like the dense raindrops.

The Jin army's arrow tower catapults began to move slowly, and each arrow tower was already full of golden soldiers with longbows, who hid behind the thick beams of the arrow tower to avoid the Song army's bows and arrows.

Behind each catapult, there were several golden soldiers pushing carts full of stone bullets, and like the golden soldiers on the arrow tower, their eyes were full of excitement and murderous light, as if the city of Tianfu was broken in front of them, and they could burn, kill, loot and wanton like those cities that had been broken before.

Even in the rain, the creaking sound of wooden wheels still clearly reached the ears of everyone in the city, and the giant spears and iron shields at the front were still tightly closed, and the steps were neat and unhurried towards the city gate.

A cry rang out from the top of the city.

"The Golden Dog is coming! The Golden Dog is coming! ”

Uncle Zhang was stunned for a while, such a heavy rain, whether it was marching or fighting, it was extremely inappropriate, let alone attacking the city, he had been handsome for many years, it was impossible to make such a low-level mistake, this ......

Suddenly, he glanced at his eyes, and suddenly realized, slapped the arrow buttress and said angrily: "What a treacherous golden dog, I said that this ghost weather still dares to attack the city, and dare to love is to prevent our firearms!" ”

When he said this, the other generals in the city also woke up, and immediately scolded the Jin people, but they could scold, but there was no way, although the firearms made by Xu Zizhen were sharp, but they had no effect in the event of such heavy rain, the fuses could not be ignited, and those rocket firearms were not as good as burning sticks.

Uncle Zhang's steel teeth creaked at night, and shouted: "If you can't use firearms, you don't need them, is it really that I don't have any means?" ”

Suddenly, a joking voice sounded: "Who said that you can't play with fire when it rains?" ”

"Uh......?" Uncle Zhang turned his head in astonishment, but saw that it was Xu Zizhen who spoke, and couldn't help but be stunned for a moment, "Zizhen, you ...... Say what? ”

Xu Zizhen wiped the rain on his face with his hand and said with a smile: "Don't say it, just use it." After speaking, he suddenly shouted, "Little people, are you alive?" ”

The science and engineering department not far behind him responded in unison: "Report!" Let's live! ”

Xu Zizhen looked at the huge arrow tower and catapult slowly advancing in the rain, and a strange smile hung on the corner of his mouth: "Listen to my command, aim!" ”

"Yes, aim!" Large catapults with giant iron arms lifted the tarpaulins and revealed their hideous faces.

"The golden dog has no common sense, light a fire and show them."

"Yes, ignition!" As the words fell, a huge fire burst out from the iron pocket behind the giant arm, which was very strange, even in such a heavy rain, it was not extinguished, but instead emitted puffs of black smoke, which spread in the wind.

Xu Zizhen looked out of the city, and his lips touched: "Hair!" Shoot! ”

"Yes, launch!"

Call! Call! Call!

A whole row of catapults threw huge fireballs in unison, drawing a graceful arc in the rain, seemingly not fast, but with the sound of the howling wind, the target was the siege equipment of the golden man.

The golden soldiers all raised their necks with wide eyes, watching countless fireballs fly out of the city, and the rain hit their faces, and even fell in their eyes, no one cared, because at this time there was only one thought in their minds: With such a heavy rain, how could the Song people still be able to hit the fireballs?

The heavy rain blurred his vision to a great extent, but he still saw all this clearly, and the smile on his face froze before it could dissipate, instantly turning into iron blue, and then roared angrily: "How is it possible? How can they still light a fire? ”

Rumble! Boom!

No one has answered yet, the first fireball has accurately hit an arrow tower, and then the fireball exploded, shattering into countless pieces, and the golden soldiers on the arrow tower didn't have time to jump out in shock, but found that the arrow tower seemed to be fine? Take a closer look, and sure enough, it's okay, the arrow tower is still good.

"What kind of nonsense is this, is it used to amuse grandpa? Ha ha...... Yes? ”

The startled Jin Bing came back to his senses and just laughed and scolded for a while, but he was stunned to find an even more terrible thing, although the fireball failed to hurt the arrow tower, but the fragments of the fireball fell on the arrow tower, and then it was still burning in such a heavy rain, and even belching black smoke.

"Quick! Put out the fire! ”

The golden soldiers screamed in panic, but no matter how they tried to put it out, the fire did not stop at all, but spread extremely tenaciously.

While they were scrambling, the other fireballs had already arrived, and then they hit the arrow towers and catapults, and like the first fireball, they turned into fragments, and the fire spread.

In the blink of an eye, most of the originally majestic arrow towers and catapults were already on fire, and the golden soldiers could not extinguish the strange fire with all their might.

"Report! Marshal Qiyu, what kind of demon magic does the southerners don't know ......"

Sticky didn't drink his face was pale, waved his hand to stop the Jin Bing who reported the news, gritted his teeth and said word by word: "What a black fire oil, what a Xu Zizhen!" ”

As the marshal of the Right Route Army of the Dajin Kingdom, how could he not see any "demon law" made by Xu Zizhen? This is the black fire oil used when the Western Xia attacked Lanzhou, this thing is weird and strange in the water is not extinguished at all, it seems that the only way can only be to use sand, but let the sticky drink annoyed is here, in order to prevent Xu Zizhen's firearms, he specially let people look at the sky and choose a day of heavy rain, but the rain is falling, Xu Zizhen's other firearms are indeed useless, but the sand is nowhere to be found, such a heavy rain, the ground is all mud, where does the sand come from?

The Song generals at the head of the city were also stunned by this scene for a while, and then they all burst into laughter, and even Zhang Shuye and those generals cast extremely admiring glances at Xu Zizhen.

But Xu Zizhen didn't laugh, he knew that the golden man's arrow tower catapult was destroyed, but he should be angry if he didn't drink it.

Sure enough, before he could finish his thoughts, he heard the drums outside the city pause, and then they intensified again, and then the roar of the mountains and a tsunami came.

The giant spear iron shield long snake formation continued to press, and behind him was a black pressure of infantry, a small team of twenty people, carrying a cloud ladder on their shoulders and rushing towards the city wall, and the golden soldiers began to attack.
