The most essential difference between this last type of fire bomb and the thunderbolt is that the outer shell is no longer paper, but iron.

Although its inner wall structure is similar to the previous thunderbolt, after changing the shell and the ratio, when the inside burns, the pressure will double, and the explosion will be more powerful!

This should be regarded as the ultimate version of the thunderbolt, which is a bit like the blooming shell used by the Ming Dynasty artillery, but Xie Linlang didn't want to think about artillery.

This kind of simple structure of the thunderbolt, she recalled the anatomical drawing seen in the museum, and then she could make it with the craftsman.

But Xie Linlang could not study this in the last life of the cannon, and in her memory, the smelting process and design process did not meet the standards, and the cannon would be broken after two strokes.

She has oil at the moment, although it can reach a higher smelting temperature, it does not mean that she can waste oil to smelt.

She hasn't done this since, except for burning steel when building a high-temperature steel boiler.

She can't do mass production of steel, and others can't, so she doesn't have to worry. After her fireballs are learned by others, they will be inspired to make weapons like artillery.

The technology in the environment of this era does not allow it, and what she took out is already the most powerful weapon!

After this kind of thunderbolt was taken up, the guards who set the fire were stunned for a moment, but the enemy had already attacked and they couldn't allow them to hesitate.

Because this kind of thunderbolt is heavier, even if Xie Linlang's thunderbolt is powerful, the throwing distance is only about 100 meters, but it can just attack the enemy rushing in front of him.

And this kind of thunderbolt will not catch fire outside, so the people on the boat below can only see the traces of the traces of wires passing through the sky, but the next second, the explosion sound is shaking the sky!

This kind of thunderbolt is not easy to misfire, and many of them explode directly when they fall into the water!

The explosive power is so powerful that if you get close, you can directly blast through the bottom of the ship!

If it falls on a ship, only one light battleship will be scrapped, because the power of its explosion can shred the wooden planks three meters away!

If a person is nearby, it will definitely blow up instantly. Compared with the previous blasting bullets, this is nothing like the same weapon!

The surface of the water was exploded by iron shells one after another, causing huge splashes of water!

In the screams of the enemy's horror, the thunderbolts that detonated the hull were like fireworks on the water!

All the ships hit were on fire or sank quickly. Such terrifying power made all Ze Jun panic!

"No! Those who can't get past, those who can't get past! They have magic fire in their hands!!"

In order to save their lives, the front warship retreated in a panic, while the warships behind did not react in time and directly collided together, causing even greater casualties!

Chang Qiyu stared at the sky full of flowing flames, as if he wanted to see clearly what the missiles were.

At this time, an iron shell hit a ship beside him. The speed was so fast that he could only see an iron ball falling down, and then a huge firework exploded!

One-fifth of that ship was blown up instantly, killing at least a dozen people!

In a wailing sound, the hull of that ship resolved and sank quickly!

The surviving navy hurriedly swam towards the other ships nearby, but the unconscious and injured people sank along with the dead bodies.

And in the ear, the explosion sound comparable to thunder continued...

Chang Qiyu looked up, staring blankly at the sky full of flames, watching the terrifying firearms mingled with the flames, set on the deck for a while, and only felt a sweet throat!

At this time, an iron shell bomb exploded beside his ship, and a huge splash of water shook his ship!

Chang Qi Yu was suddenly lost and almost fell into the water. Fortunately, his lieutenant caught him in time and said with red eyes.

"Your Highness! Retreat... we have no chance of winning..."

Quit?

Chang Qiyu looked at the countless burning warships in front of him, at the soldiers who were blown up, and at the sky full of fire and the bodies of the river.

If they retreat, the two countries' plans for many years of deployment will eventually come to nothing.

The three hundred thousand troops of the Marsh State and the four hundred thousand troops of the Ze State, once they retreat, their losses will hurt their roots, but they will get nothing.

But if he doesn't retreat, how much can his 200,000 navy army survive?

If most of these navy forces are buried, will the floating countries around Zeguo let go of this opportunity?

This is a dilemma. Both advance and retreat are cutting the flesh!

He wanted to grit his teeth and say "forward" and "strike", but at a distance of more than 100 meters, they would definitely be able to pass!

But in the light of the fire, he saw the corpses floating on the water among the boats. Those orders seemed to be choked in his throat, and he couldn't say anything.

At this time, Xie Linlang suddenly raised his hand, and the people behind her stopped suddenly, and the fire in the sky suddenly fell silent. After the explosion disappeared, the wailing voice became more obvious.

Xie Linlang is still sitting on the edge of the city wall, her legs hanging in the air, her back standing upright, and a string of Buddhist beads in her hands.

The bombing ceased, but no enemy dared to take the opportunity to move forward. The people who were still alive stared at the sky and looked at the direction of the water barrier. There, she could be seen vaguely.

Xie Linlang used his internal force to transmit the sound, transmitting her voice as far as possible.

"The soldier opposite, please listen to my last advice."

"If you insist on fighting, the remaining bullets and fire from me can wipe out half of your lives, even if you rush over, kill me, and take revenge, the rest are just remnants of defeated generals, and you can't fight the marsh. Military alliances cannot support the next land battle, so do you really want to continue?"

The Red River Valley happened to be stuck in the middle of the Wanjiang Gorge. The width of the Wanjiang Gorge is only 400 meters wide and two hundred meters narrow. Excluding the places where the shallows cannot be sailed, her water barrier is nearly 100 meters long. Can cover most of the waters.

More than a hundred meters, it seems to be very short, but if they really want to rush over, there is only one way, and that is to pave the way with their lives!

But in this situation, do they really have to work hard?

When Chang Qiyu heard this voice, he finally vomited a mouthful of blood, frightening everyone around him.

Xie Linlang's voice did not have the predominant arrogance, and there was no compassionate sympathy, some were just calm, she was calmly telling the truth.

She was telling him that even if he rushed past, the navy would be in a slump, and the plan of the two countries had been shattered the moment she took it, and she advised him not to make unnecessary sacrifices.

When the soldiers around him heard the words, they all showed a desperate attitude. The lieutenant beside him supported him and couldn't help crying.

Chang Qiyu looked at them, listened to the screams of his own people on the river, looked at dozens of burning fire ships and the water barriers in front of him.
