The next morning, the morning light of winter shines among the countryside that has long lived up to its beautiful scenery.

Outside the north gate of Hangzhou City, war drums sounded at the imperial guard camp. Thousands of imperial guards who were trying to attack the city pushed the tall ladder and slowly headed towards the north gate of Hangzhou City. After all, Fang La soldiers on the city wall were densely filled with shadows, and the crossbows were lined up in line. Some rebels stood beside them holding torches, preparing to light the "rocket" mounted on the arrows on the bed.

War is always accompanied by rapid improvement in technology. As long as one side has very useful technology, such as Madang, the enemy will always learn it as fast as possible if it suffers losses. After many ladders were lit by shoddy rockets in Muzhou, Fang La's army obviously mastered this technology. However, facing the imperial siege, this technology can only be said to be better than nothing. It is impossible to burn the huge ladder three-story high, and at most burn some imperial soldiers.

Wang Bing stood in the commanding account to supervise the battle. Looking at the side of the siege team, a small group of infantry pushed the car forward quickly, frowned slightly:

"Governor Cao is really useful?"

Tong Guan was slightly contemptuous: "Since he was going to take the lead, let him go, and the army was not allowed to withdraw without the sound of gold. Those who retreated might be killed. Maybe he could really rush up to the city wall and kill a pair of people later."

On a hillside on the side of the Imperial Guard Camp, King Kang and Song Yang stood together, holding the telescope sent by Bianjing just now, looking at the city of Hangzhou in the distance, and seeing the present since the early morning.

Due to his professional habits, Cao Hua dares not say what he created. The beauty is absolutely rare in the world. He forged a copper tube in a telescope, wrapped in golden silk, and his patterns are all designed by him. It is probably a valuable handicraft on his descendants. Song Yang held it in his hand and observed it carefully for a long time, but he felt that he could not put it down.

King Kang was not tired even though he was holding the telescope. After seeing many attractions in Hangzhou City, he moved back to the imperial guard camp and glanced for a moment and sneered:

"This Tong Guan has nothing in his crotch, so why should he take out the crotch?"

"Um?"

Song Yang's eyes lit up, and he hurriedly raised his telescope to check it out. Unfortunately, General Tong had already returned to his former majesty. So he turned back to the right side of the siege team and looked at the prince Zhao Huai who was pushing the cart:

"Prince, will your prince run to attack the city? Will something go wrong?"

King Kang looked at the big cart covered by red cloth, with a plain expression: "War is always going to die. The people's sons can die, so why can't my son die?"

Song Yang knew King Kang's temper and didn't say much at the moment.

--------

"Brother-in-law, this thing is less than two thousand pounds, it's so heavy."

On the right side of the siege team, hundreds of infantrymen pushed four cannons and several small cars, moving slowly on the frozen mud, and gunpowder was placed separately on the small cart to prevent a little spark from directly exploding and sending everyone to heaven.

Zhao Huai gritted his teeth and pushed the light cannon tube with a huge three-meter-long cannon. The touch of Huanghuai is very comfortable, similar to the carved soft couch in the royal palace, but this thing is really heavy. The wheels drove out deep marks in the mud, and the boots were almost broken. Zhao Huai, who was still handsome and handsome, had already blushed and breathed like a cow.

Cao Hua rode a horse next to him, looked at him for a few seconds, and called Si Zhongzhubo: "Remember it, let the craftsmen think about whether they can change to using horse pulls, so people push it too slowly."

The anchor nodded, took a small hair in his mouth, and wrote it carefully on the booklet.

The four "Grandmaster Guns" were tested in Bianjing for a maximum range of about four and a half miles, and the effective range that could be accurately measured was only two miles, within the coverage of the crossbow. The team did not approach the city wall, and stopped on a small hill two miles away in Hangzhou City, putting gunpowder more than ten meters away to prevent Fang La from coming and sending him to see the Buddha.

After the four cannons were lined up, the red cloth was pulled off, revealing the cannon painted ink black with precious paint. In order not to affect the strength of the barrel, only a black hawk was drawn on it. It is said that it was also written by Fan Chenglin, one of the four talents in Tokyo. It was lifelike and the word "priced" was written all over his body.

Under the command of the chief clerk, many infantrymen used iron brazers on the cannon to fix the cannons. There were sights on the cannons, which were recorded in detail after many experiments by Diankuis, with distance, elevation angle, loading amount, etc. The main pen carefully followed the booklet and weighed the gunpowder with a small scale weighing Chinese medicine. It was no less than a minute. After loading from the muzzle, it was compacted with a wooden stick, and then a solid iron pill was loaded.

Although it took half a quarter of an hour to complete the set, it was full of craftsmanship and seemed to be guaranteed.

Cao Hua hugged his arms and waited for a long time. Seeing that the siege troops were about to arrive in Hangzhou, the four cannons were loaded.

Zhao Huai looked at the big guy in front of him and stood in front of him and muttered softly: "Brother-in-law, this thing is really better than a bed crossbow? It looks quite mighty, but it is a bit too bulky."

Cao Hua smiled and after the loading was completed, he lit the torch with a fire fold and handed it to Zhao Huai:

"I've given you this opportunity to fire the first shot, cherish it." Then he took Han'er back a few feet away.

Zhao Huai raised his head and was still curious, holding the torch and listening to the master Bo explain how to ignite the fire.

"Prepare!"

The chief clerk of the Sizhong aimed at the target, and after checking it, he gave an order. Zhao Huai and several black feather guards stood on the side of the four cannons holding torches.

Han'er still looked cold and looked at the north gate of Hangzhou City with a telescope.

Cao Hua looked at her for a few glances, walked behind her back, covered her ears with his hands, and placed his chin on Han'er's head to watch the battle.

Han'er was stunned, glanced up at her eyes a few times, thought about it, and actually put away the telescope, raised her little hand and walked around her back, covering Cao Hua's ears.

Not to mention, this looks quite warm.

"fire!"

Boom boom boom boom boom boom-

On the third day of the second month of the second year of Zhaohong, four loud noises exploded outside the north gate of Hangzhou.

The sound is like thunder, and it travels from afar for miles.

Many generals and soldiers in the imperial guard camp were shocked, and tens of thousands of soldiers looked back together.

Four flames were like fire pythons that swallowed the city, accompanied by thick smoke, sprayed out several feet apart. Before they could see clearly, they heard another sound from the north gate of Hangzhou.

In a blink of an eye, two big holes appeared on the north gate of Hangzhou two miles away. A corner of the city tower above collapsed, a gap was broken through the walls, smoke and dust rolled, and screams and roars continued.

Bang-

In the central army commander's tent, Tong Guan and Wang Bing's tea cups fell to the ground, one was shocked by the loud noise, and the other was shocked by lethality.

One shot can destroy the walls. If you hit the city gate, you can collapse the heavy Hangzhou city gate in just a few strokes. No matter how many sandbags of logs piled up behind it, it will not be able to hold it up sooner or later.

Wang Bing stood up and was shocked!

The loud noise reached the hill, and King Kang was frightened and then looked ecstatic and laughed:

"What a great commander-in-chief, just like Cao Hua, you can be worthy of this name and continue to fight for me."

Boom boom boom boom boom boom-

Half a quarter of an hour later, four loud noises were raised on the Hangzhou city walls.

Fang Qifo rushed up the Hangzhou city wall like a ghost. When he saw thousands of soldiers running away with their heads in their arms, shouting, "God, Lei Gong is angry...", and ran under the city wall.

Two battlements of the city wall were broken, and the solid iron balls also blasted the inner battlements, and the rolling wood and stones and other guarding equipment were split into pieces. Many rebels were injured by gravel and lying on the ground and rolled and wailed.

Fang Qifo's face changed slightly. He ran to the outside of the city wall and looked at it for a few times. Thousands of siege imperial guards outside the city also stopped and were looking around in a daze, but he had not yet reacted. A few rising smoke on the hills on the north side were exposed, and the location of the culprit was exposed.

"Shoot the arrow, north, hurry!"

Fang Qifo shouted like thunder, almost spreading half of the northern city wall. After a moment of riot, the leader of the rebel army hurriedly turned over more than twenty three-bow crossbows and shot at the smokey place in the north, and more than a dozen black smoke rose up.

Cao Hua fired two rounds of cannons, then quickly pulled out the iron rod of the fixed cannon, and retreated several cannons to the rear of the earth mound. A hundred infantrymen also hid and guarded with shields.

But in a moment, several "rockets" landed nearby, and after landing, they exploded and brought out surging fireballs. Unfortunately, the angle problem could not hurt the infantry behind the cover.

Zhao Huai was trembling and covered his ears, his face flushed and hid behind the infantry, and said loudly:

"Brother-in-law, this thing is so fierce, thick and long, just as fierce as drinking tiger bone wine treasured by the father..."

Bang-

Cao Hua slapped his forehead: "What are you doing so loudly?"

Apart from the sound of a few "rockets" exploded, the surroundings were actually very quiet. The sound of the cannons just now was too loud. Dozens of infantry nearby covered their ears and spoke almost at the top of their throats. The excitement on their faces was hard to hide.

Zhao Huai just stood next to the cannon, but he didn't cover his ears when he was careless. He was still buzzing and laughed:

"Brother-in-law, there are a hundred great generals. There is no city in the world that cannot be captured. If you give me one, just one. I may give you some of my sisters..."

Cao Hua raised his hand and came up on the back of his head again.

A moment later, there was a shout of killing outside the hill:

"kill--"

Dongdongdongdongdong-

The war drums for siege finally sounded, and the imperial guards who siege finally reacted from their surprise and began to siege the city. The Fang La army's bed crossbow did not shoot at the direction of the earth mound anymore.
Chapter completed!
