Today, the number of artillery equipped in the Boluo army has exceeded that of all armies except the Shenzhou army, and because the Qing army was defeated at the city of Nanchang, it received several blind fires, and the "rockets" used by the Shenzhou army were studied. Although no progress has been made in the fuze due to the limitations of the anti-demolition mechanism, it has learned a lot in the appearance. Although there is no impact fuse, it can be used using the "fire twist delay". Although it does not launch in a box or direction finder mode, it is much more advanced than the rockets used by the Ming army that use wooden poles as directionfinders.

Not only that, but Bolo's own Bolo rockets were also loaded on his own chariots and ships. It can also reach a range of about 300 meters, and although this scattering weapon is really limited in naval warfare, it has achieved good results in firing at land targets, which is why Bolo has equipped a considerable number of vehicles with this object.

When the Qing army camp on the other side of the river exploded in the air with a tail flame rising in the sky, the defenders hidden in the fortress of the "Suzhou Defense Line" were also awakened by the sound of sirens.

Looking out from the shooting holes in the fortress, chariots rushed out of the dense forest on the opposite bank, swaying their bodies that looked dark in the moonlight like moving rocks and slowly drove towards the river. The chariot in front of it rushed down the river bank and made a considerable splash.

The roar of the "woo" siren echoed in every fortress of the "Suzhou Defense Line".

"Here comes the Tartars...... The Tartars are coming......" With the sound of sirens inside the fortress, the soldiers on the Suzhou defense line opened their sour eyes full of feces from their sleepiness. Just when most people are not yet awake. The Qing army had already fired the first shot.

"Whoosh...... The "...... is the Qing army's rockets spraying tongues of fire, like a large group of meteors, rising from the ground, flying across the river, dragging a long tongue of fire, and falling to the bank of the "Suzhou Defense Line".

With every tremor of the bowstring on the "Bolo Rocket" mounted on the chariot, more than a dozen rockets that were already burning with flames rose into the air, drawing bright arcs of light in the sky.

"Boom...... Rumble...... All kinds of artillery that had quietly entered the position as early as a few days earlier, "booming...... "roared to the sky" and fired one after another at the fortress of the "Suzhou Defense Line."

At this time, the first shells and rockets that landed on the ground exploded near the fort, and large clouds of smoke rose in the explosion, and shrapnel mixed with the frozen ground turned up by gunpowder rose into the air.

The blast of the explosion swept like a storm around the fort. Violent currents blew out the glow of individual searchlights, and the smell of rotten eggs wafted through the fort. It's just that the smell isn't so pronounced because of the chaos and the smell of a lot of sparks blown in by the wind.

"Don't mess around...... Don't ......mess around" Because when he heard the news from his eldest brother, Wu Shengtai had already gotten up and lay down when the first shell exploded, and ran to the front line of defense with his own soldiers. At this moment, he and the generals who led the troops shouted hoarsely to the soldiers of the ragtag army who began to chaos as soon as they heard the sound of artillery.

Inside, however, most of the lights were either not lit or blown out by the blasts, making the darkness even more chaotic. The motley soldiers didn't know what they were supposed to do, and they scurried back and forth inside the fortress with their heads in their hands.

At this moment, a "Bolo rocket" like a fire meteor fell down with a tongue of fire, and a "crackling" sound like a torrential rain sounded outside the fortress.

The Ming positions of the "Suzhou Defense Line" were lit everywhere with large fires. The main targets of the rockets and artillery fire were the sloping and sharp wooden horses that prevented the chariots from coming ashore, and the patches of wooden horses burned in the flames, and the roaring light of the fire illuminated the sky and the chariots that rushed to the opposite bank in the river.

The soldiers of the Ming army of the "Suzhou Defense Line" cowered in the fortress, enduring the thrilling explosions caused by the first wave of artillery fire and rockets of the Qing army, as well as the thick smoke that seemed to be burning everywhere, choking the soldiers at the lookout to tears.

Fortunately, relying on the fort fortification, the shrapnel of the horizontal plate could not effectively harm the Ming soldiers who were hiding in the fortress. Just when the frightened Ming soldiers were still rejoicing in the fortification of the fortress, the Qing army's attack became more and more fierce.

"Fight back...... Shoot back......" The Ming generals who led the troops shouted loudly, driving the soldiers who were frightened by the fierce artillery fire to their battle positions.

The ragtags, who were stunned by the heavy artillery fire, came back to their senses under the roars of the officers and the shouts of leather whips. It was also at this time that they realized that the light in front of them had been extinguished. Without thinking too much about it, he reached out and took out the fire knife, and the flint was about to be lit, and the searchlight was lit again.

"Huh? What does it taste like...... Don't ......" At this time, Wu Shengtai, who had just come back to his senses, suddenly found that in the thick and choking air, there seemed to be a hidden smell of acetylene's peculiar rotten eggs.

Suddenly, he recalled that the merchant who came to adjust Shenzhou City had said that although this kind of light was extremely bright, once it went out abnormally, the valve should be closed and the reaction should be stopped, otherwise it would be ......, but it was obviously too late for him to remember.

The word "don't" has just been exported.

......The acetylene gas, which was well mixed with the air, was ignited by the sparks that burst from the collision of the fire knife and the flint. The sound of explosions in the fortress was a little dull, and heavy smoke mixed with fire rushed out of the lookout. Almost at the same time as the explosion here was made, there was a dull sound among the other forts on the front line, which showed that they were not the only ones who were experiencing this problem.

The people in the fortress felt as if they were being weighed down by something extremely heavy, and the air was so hot that they could barely breathe. One by one, the living people bent down and offered themselves to all the corners of their bodies that could be hidden.

Fortunately, there was not a lot of acetylene gas leaked, and the explosion was not very strong, and only a few people were killed by the explosion. Most of the soldiers who were a little further away from the blast point were simply stunned, but this also deprived them of the best opportunity to resist.

Wu Shengtai, who found out that the abnormality was not killed, it was his own soldiers who pounced on him and shielded him with his body from the impact of the explosion. He was just slammed against the wall by the blast and knocked unconscious. When Wu Shengtai slowly woke up, he found that the fortress was a mess, full of lying human bodies, and some fires were still burning on debris or corpses.

"Close all generator valves......" he shouted in a voice that was hoarse from the smell of gunpowder.

Suddenly, someone screamed with a frantic cry: "Tartar chariot...... The Tartar chariot is coming, brothers, fight it! ”
