After a day, the three armies in the city of Beizhou were overwhelmed.

In the evening, the airboat was slowly retracted. Almost all the soldiers rushed over together, looking at this behemoth, and thundered with joy. Shi Heng brought down ten soldiers and received heroic courtesies together.

The next day, we flew again.

It was too shocking. In the afternoon of the next day, he received a decree from the imperial court, asking if he could let this large balloon fly to the capital after destroying the rebels. Zheng Lang was stunned, flying from Beizhou to the capital, he had to pass through the Daimyofu, Dezhou, and Huazhou in order to get to the capital. Spanning hundreds of miles. It's okay to walk around a radius of dozens of miles, but fly hundreds of miles...... He thought about it and gave an answer, depending on the weather, if the weather is good, it can be done, and if the weather is bad, it can't be done.

It is possible to adjust the direction, the first premise is the breeze, the wind is big, and it still can't be done.

If the wind is not strong, it is still okay to make some additions along the way. Zhao Zhen also wanted to see a novelty, and Zheng Lang took the opportunity to promote the power of science, so that more and more people became interested in Gewuxue. Now there are people in Taixue who study Gewuxue, but there are too few of them, and Shi Heng wants to study the same thing, but he can't find a helper.

The impact is significant.

Someone will learn right away.

On the third day, that is, the sixth day of Zheng Lang's arrival in Beizhou, the wind became strong, and he had to fly only once and stop. Then it got dark, and it started to rain lightly. The spring rain is as expensive as oil, but Zheng Lang looked at the various Buddha flags in Beizhou City and sighed.

In the evening, when the rain gradually subsided, suddenly the soldiers came in and reported: "Zheng Xianggong, look at the city." ”

Zheng Lang walked out of the camp tent and looked at Beizhou, where more than a dozen hot air balloons had risen in Beizhou City, and hot air balloons were rising one after another.

Wang Ze was also forced to be helpless, several bed crossbows were all destroyed, and there were some strong crossbows and large stone throwers, but the range could not reach an altitude of more than 100 meters, but the airboat was always floating at a height of 100 steps, and there was no way to take it.

It just so happened that a balloon was captured in the city. It was not difficult to copy it, so they looted the hides in the city and made a large number of hot air balloons. It was impossible to let them fly like airboats, and they continued to be hung with ropes underneath. But the victory lies in the large number, once the airboat arrives, intercept the airboat, and be sure to destroy this behemoth, otherwise the subordinates in the city will seize the air, and this battle will not be fought.

Zheng Lang suddenly laughed and said, "Want to fight in the air? ”

I want to fight in the air. Accompanied.

On the seventh day, it was another good day, and the airboat was raised. But this time, for the sake of height, the second layer of cotton protection under the airboat was also removed to loosen the pressure on the airboat.

Even cut the ship's side in half.

The number of men in charge has been reduced to eight.

There are some supplies and some stones on it.

It slowly rose up, and because of the large number of rocks pressed, the height remained at about three hundred meters, which was comparable to these balloons. The rope was not loose either. Slowly came to the top of the city and threw down a stone. The weight was gradually decreasing, and the city had to connect the ropes. Continuing to release, the altitude of both sides is increasing, and gradually it reaches 350 meters, and some balloons cannot rise. It has nothing to do with the rope, the main thing is that the size of the balloon is too small to carry the two soldiers of Hanging Blue and rise to a higher height. But in order to confuse the other party, Shi Heng ordered: "Stop." ”

Then he slowly pulled the rope onto the gondola and flew over to the row of hot air balloons.

There is actually another way. Make a small bed crossbow, and change the crossbow head to a more scientific rocket, and aim it at these hot air balloons, if you keep the distance within a hundred steps, the bed crossbow has some accurate heads.

But Zheng Lang abandoned this method. It's too trivial.

The king commanded the soldiers to drag the balloons, a total of twenty-one balloons. Yesterday it took a day and midnight to make it, and I wanted to have a fight. That's it, the morale of the city is still plummeting, and the two are too different in size, one is an ant and the other is an elephant. However, the rebels had the rebels' methods, and the two soldiers on the hanging blue were fully armed, holding grappling hooks and broadswords in their hands, preparing to forcibly board the boat without fear of death when the two approached. …,

Seeing that it was approaching, Shi Heng said, "Let's go." ”

Directly open the plank and push the stone down. In the blink of an eye, the airboat was another hundred meters high.

This once pressed all the hot air balloons under the body, fortunately, the wind is still very small today, otherwise the air flow at this altitude is strong and difficult to control. Several pipes open together, steam is released, and the sails are hoisted, increasing their speed, quickly coming above these balloons.

Shi Heng shouted again: "Release!" ”

Rocket after rocket ejection.

The rebels in the city saw that it was not good and wanted to take back the balloon, but its volume was too large, although it could not be compared with the airboat, since the balloon could bring two soldiers into the air, the volume was not small, and half of the rockets of the Song army were hit. Constantly controlling and flying from south to north, in just a moment, all twenty-one balloons caught fire.

Seeing this wonderful scene, almost all the Song soldiers shouted together: "Long live the Great Song Dynasty." ”

It's so exciting, it's so spectacular, this trip to suppress bandits, just seeing this scene, it's worth coming. It's like watching it as an eleventh-century blockbuster.

Set all the balloons on fire, without haste, adjust the airboats, fly from north to south, discharge hot gas through the pipes, reduce the height, and throw stones all the way down, as a result, the rebels below ignored the brothers above, smashed it too much and let go of the rope. As a result, some balloons with fire actually floated outside the city and were captured alive by Song Junsheng, and some were shocked to death because the fire burned fast and fell quickly.

Wang Ze didn't make a scene of pseudo-air battles, but if he did, his morale fell even more.

The airboat returned again, reloaded, this time loosened, the loading was greater, and more soldiers went up, reaching sixteen. The airboat is big, the boat is not small, plus the soldiers on it, it is more like an airboat dragging a ship to fly in the blue sky.

Controlling it, flying everywhere above Beizhou, flying wherever there are rebels, and then pouring sulfuric acid and gunpowder down, or throwing it down. In fact, at this point, there are many rebels in the city who are ready to be captured, but they are afraid of Wang Ze's prestige, they dare not make a sound, and they reluctantly defend Beizhou City.

After walking around and returning to load again, he saw the airboat flying over, and a few of the rebels were demoralized, put down their weapons, and shouted outside the city: "We surrender." ”

As he spoke, he jumped on the dirt mountain and ran in the direction of the Song army's camp. The king couldn't stop it.

Zheng Lang saw that the heat was almost over, and this time he did not load weapons, but lowered the height of the airboat further. As low as about one hundred and fifty meters, let Shi Heng shout with a big horn that the city will be attacked in the afternoon, and it will be broken. All the innocent people, as well as the demon cultists who surrendered, wore white belts on their heads, and all gathered in the west of Beizhou City, not allowed to hold any weapons, and waited for the arrangement of the imperial court.

After shouting around the city, it was raised again. Watching the city's movements.

Chaos began in the city.

The Song army had not yet entered, and many of the people fled to Xicheng.

The king would never let this happen, so he sent soldiers to stop it, and drove the residents of Xicheng out, but the people did not listen, raised their butcher knives and began to slaughter.

Zheng Lang stood on the top of the highest earth mountain outside the city, also watching this scene and shook his head. Although it is a little more miserable. Or in this way, the common people can come to their senses. When it was time for lunch, Zheng Lang summoned the generals. Prepare for the general attack.

People are selfish after all, Zheng Lang put Zhang Kang outside the East City Gate.

After the dispatch was completed, Wang Xin led the army, blew the horn of the charge, took the Song army to climb the Tushan, returned by airboat, and again brought sulfuric acid to the head of the north city and poured it down.

Even at this time, there were still many believers who did not know whether they were alive or dead.

There was no immediate siege. Sulfuric acid is poured on the top, and the bow and arrow are shot below.

In fact, there is no plan to really storm the north city gate, and the main direction of attack is in the south city.

When he came, Myeongho dug tunnels for several days, leading straight to Beizhou City, and had not yet passed through the city wall. Zheng Lang has used airboats to attract both sides of the enemy in the past few days. Secretly dug the tunnel all the way to the foot of the city wall and stopped. …,

The dug mud was piled up in tents and transported out at night.

However, he did not learn Wen Yanbo to select 200 strong men at night, entered the city from the tunnel, re-ascended the city, killed the defenders of the city, and lowered the rope to lead the officers and troops to the city. It is possible that some tactics were used, but the rebels did not have much fortification that night, which led to a large number of Song troops ascending to the top of the city and opening the west gate. In a hurry, the king used a fire ox trick to trap the officials and soldiers, but to no avail. So they fled from outside the eastern gates.

This plan has infinite variables and is not required.

Zheng Lang adopted Hong Xiuquan's strategy of attacking the city of Nanjing, gunpowder.

The Nanjing city wall is far higher than the Beizhou city wall, Hong Xiuquan can not be restrained, and finally his subordinates came up with a strategy, stealing the coffin from outside the city, the coffin is filled with black powder, and the coffin confined space is used to enhance the air pressure of black powder, and the tall Nanjing city wall is shattered.

This is also the first time in human history that the air pressure generated by the explosion of black powder was used to collapse the city wall. Although it came out very early, there has been no comprehensive understanding. Otherwise, human history will be greatly rewritten.

Easier said than done.

It's not that simple, such as the Zhonghua Gate in Nanjing City, no matter how big the coffin is put underneath, it may not be able to collapse.

There must be other insiders to this, such as the weak place of the wall foundation, that is, the soil is damp, the wall has evolved over the years and is not so strong, or other things, which are not recorded in the history books. However, after Shi Heng received Zheng Lang's instructions, he rode to a coal mine with his sister-in-law, tested several times, and obtained some detailed data.

In the air battle in the morning, Zheng Lang secretly sent people to arrange it below.

He would not learn from Hong Xiuquan and steal the coffins of the dead from the city, but deliberately built several heavy wooden boxes, far larger than the coffins, filled with black powder. The wooden box is also carefully set up, thicker around and below, only the wooden plank above the center is thinner, so as to ensure that in the event of an explosion, the air pressure is aimed at the wall above.

And not only that.

On the fifth day, another feint was launched outside the southern city gate, covered by airboats, and wooden stakes were laid, preparing to build several high platforms and force their way to the city. However, the rebels in the city resisted, but they were unsuccessful, and only a few wooden stakes were pierced.

It is enough that these stakes are marked, otherwise people below will not be able to prepare to measure the position of the city wall, and if they are a little bit up, the air pressure will rush out of the ground, instead of rushing to the city wall, it will have no effect.

The soldiers entered, filled the gunpowder, and the fuse was drawn out with a bamboo tube, and the soil was tamped with glutinous rice juice and lime. Then the mud was poured with quicklime and glutinous rice juice, sealed on the outside, and even a few stones were removed to make the passage stronger. Slowly withdrew, until fifteen meters away, before stopping the tamping work.

The three tunnels were prepared, and the soldiers retreated.

Zheng Lang looked at the sun, the north side was in full swing, but the south side was quiet, and a few small birds flew over curiously, hovering in the sky, watching everyone sing with a tactful voice. The bitter cold of winter is gradually passing, and there is still some chill in the air, but you can smell the intoxicating smell of spring.

Zheng Lang muttered: "One will be a success, and ten thousand bones will wither." ”

No matter how he spares it, many, many people will die today.

After speaking. With a wave of his hand, the soldier lit the fuse.

Zheng Lang shouted: "Cover your ears." ”

The amount of black powder not used in Shimenchuan is large, but the sealing is stronger than that of Shimenchuan. It would be better if there was yellow powder, but there was no detonator. I can only sigh with admiration.

Coincidentally, three loud noises were heard.

The effect of the three blasting points was different, although one blasting point was corrected with a wooden stake, but I don't know where it went wrong, the direction of the explosion was biased outside the city, and it flew into the sky with countless mud balls, and the city wall shook. Unharmed.

There was also a blasting point aimed at the city wall, but because the wall was too strong, only part of it collapsed, and a small gap appeared, which had an effect, but it was not very large. The gap is too small, and it can only pass through three or four people. It's easy to get the enemy to block. …,

But another place worked.

A great force rushed towards the city wall, which was like a pile of sand. After shaking it, it quickly collapsed, and a large gap of more than four meters wide appeared. Enough is enough. At this time, the main force of the rebels was in the north city, and there were not many rebels in the south city, and they were also dumbfounded.

When the explosion just now, a powerful air flow rushed up, and some soldiers were actually blown into the air by the air current, let out a miserable scream, and fell to the ground, motionless. Other soldiers were buried directly by the collapsed walls. Even though a few rebel generals were sober and shouted orders, the soldiers' ears were ringing. I can't hear it either.

The opportunity is fleeting, and once it reacts, it is difficult to storm the city by blocking the gap with a wooden fence. Zheng Lang shouted: "Attack." ”

Wang Kai and Hao Zhen led the Song army and quickly rushed towards this gap.

In the blink of an eye, the Song army entered Beizhou City through the gap.

Seeing the Song army entering, many people took the white ribbon that they had secretly prepared in their arms and tied it to their heads. Flee to the western city. Originally, it was thought that the king was Maitreya Buddha, and they fought to the death one by one. But in the past few days, more than ninety percent of the people will not think that Wang is Maitreya Buddha, and their heads are sober, even if they are illiterate, they know the seriousness of the matter. What is this place? Hebei is a strategic place, only a few hundred miles away from the capital, and an important northern gate of the imperial court. If these people rebelled, could the court be good?

One by one, they only hated their father and mother for missing a leg, and they ran away desperately. Many of the rebels also hurriedly unloaded their armor and weapons, trying to get caught in the crowd. However, armor is not clothing, and it takes a while to put on and take off the parts before they can be assembled or removed. Seeing Song Jun coming, he was nervous, crying in fear while taking it off.

Ming Ho looked at this scene, knowing that Beizhou City was almost equivalent to taking it, so he didn't care anymore, turned his head to look at Zheng Lang and said, "Xingzhi, this gunpowder technology can't be passed on." ”

It scared him.

It is very likely that this can be used to capture Lingzhou City, but if the Khitans can go, or the Tanguts can go, they can also use this technology to capture the Song Dynasty city wall. Compared with the tall and sturdy city of Beizhou, how many walls can the Song Dynasty catch up? Especially the bunkers on the border, which are almost broken.

Zheng Lang nodded and said, "Not only that, even all the soldiers who participated in the blasting must also sign confidential documents with them. However, with the development of Gewuxue, the role of the city wall will gradually decline. ”

"Xingzhi, how is that good?"

"Brother Huaji, it doesn't matter, once Gewuxue develops, it will also be a nightmare for the nomadic cavalry, and the competition will be who has more knowledge of Gewuxue, who has more financial resources and materials, and who has more population base."

Zheng Lang didn't explain much. Which country has the largest population, which country attaches the most importance to learning, and which country has more financial resources and materials? Only the Song Dynasty. But after a pause, he said: "But it is still very far away, I estimate that it will be at least a hundred years, and without a hundred years, the technology will not mature." ”

The foundation is too poor, if you are a scientist, you can still have an early industrialization. But I am not, I just learned some mathematics, physics and chemistry knowledge from elementary school to middle school and university, and some of it has been forgotten. It takes a long time to turn some of your memories into practice.

10,000 Song troops flocked in, Beizhou City was originally demoralized, seeing the Song army killed, only a few people fled to Xicheng District to wait for the imperial court arrangement, most of them were too late, the Song army covered up. So he tied a white ribbon and knelt on the ground and begged for mercy. The king saw that it was not good, looked up to the sky and sighed, and led his cronies to the east city gate, wanting to escape from the east city gate.

Where to flee.

Shi Heng stared at them closely in the air, followed slowly with the airboat, and then shouted with a loudspeaker: "The thief is here." ”

From time to time, sulfuric acid was poured on them, and even Wang Lun was hit with a few drops of sulfuric acid, painful and hateful, gritting his teeth. was forced to be helpless, took off the dragon robe on his body, and wanted to get by. But it still doesn't work, it's only one hundred and fifty meters apart, it's not okay to stare at everyone, it's not difficult to stare at one person. The airboat followed him closely. Wang Lun was forced to be helpless, and led his subordinates into a private house, which turned out to be called Luoyang Mansion, a very large house, and his subordinates flocked in and scattered out. This trick really worked, Shi Heng lost his target in the sky, so he had to follow these deserters to the east city gate.

When he opened the east city gate, Zhang Kang had already dug a trench and prepared his troops. Wang Ze's men were worried, and gathered around Wang Ze and asked, "King, what should I do?" ”

As the target came out again, a soldier with good eyes recognized it and shouted, "The thief is here." ”

The king was angry and wanted to give birth to wings, flew onto the boat, and killed the sixteen people. The battle was too humiliating. (To be continued.) If you like this work, you are welcome to (.) to vote for recommendation, monthly pass, your support is my biggest motivation. )
