Seeing the fighter plane right in front of you, peerless skills are at your fingertips.

At this time, the Mongolian Navy General Mahaye ordered the fleet to adjust its formation without hesitation, and the entire army rushed towards the bay under Yuguan.

In his fleet, forty-five gunboats led the way, and behind them were big-bellied troop transport ships loaded with countless Mongolian cavalry, and supplies ships filled with shells and rations were placed at the end.

As the Yuguan city wall in front became clearer and clearer, all the gunners on the ship were ready to fire on the city wall.

Four miles away, the sails of the Mongolian army's gunboats were full of wind and were making their final sprint! In a moment, the city wall would be trapped under their rapid artillery bombardment.

...At this time, the three Song army steam gunboats in the port were no longer taken seriously by Mahaye.

If this were on the vast sea, these three gunboats would have a range advantage of the cannon and a steam engine that would not need to sail down the wind.

They can continue to harass and attack them outside the range of the Mongolian fleet, but the current situation is very different.

These three gunboats are already trapped in the bay, not only alone but also have nowhere to hide.

No matter how sharp the artillery on their warships were, they could easily send them to the seabed by their dozens of gunships.

So at this time, Mahaye was not scruples, and as he looked at the Yuguan wall gradually approaching, his eyes were about to be furious.

But just as he was moving forward quickly, a strange scene suddenly appeared in front of him!... At this time, at the bow of the gunboat that was charging forward, suddenly, a huge bulge of several houses was arched below the sea surface! The sea water in the bulge turned into pure white due to the huge explosion.

A water column that was more than ten feet high suddenly soared into the sky! Mahaye looked at the situation in front of him in a daze, and rushed to the warship that rushed to Yuguan first. One quarter of the bow of the ship had been blown away.

The huge hull seemed to be a piece of milk tofu and was bitten hard by someone.

In front of this water column that rose from the sky, countless boat boards and garbage were blown up all over the place.

The tragic "rattle" sound made by the ship, and it stopped in front of the huge impact, as if it was hit by a blow in the head.

Before Mahaye could react, the huge water column that was lifted from the sky began to slowly descend and rumbled back to the sea.

The raised sea water was blown away by the wind, making it feel like a heavy rain around the unlucky warship! Before the waves on the sea could calm down, the warship with no bow was like a broken jar thrown into the pool, and along the huge breach of the bow was blown off into the water, and as they flipped the waves, they plunged into the sea.

There were loud shouting sailors and gunners floating on the sea. The waves that sank after the giant ship sank made the water near it feel like it was a pot.

Mahaye was stunned and found that the gunboat in front was gone! Within just ten breaths, a Mongolian army gunboat carrying twenty cannons and majestic and rushing forward was gone! "What is this?"

Everything that happened in front of us obviously exceeded Mahaye's cognitive scope.

The Mongolian navy general looked at the scene in front of him with a frightened face, feeling that time seemed to have stopped in front of him.

The scene that just appeared really looked like a ridiculous and terrifying dream! Just as Mahaye was dazed, several explosions came one after another, and they rang out from the front of his fleet.

One after another, the Mongolian gunboats that rushed to the front continued to sink one after another.

When Mahaye turned his head, he happened to see a gunboat in front of his flank, which was actually blown up half of the hull onto the sea by a violent underwater explosion.

The bottom of the boat, covered with moss and barnacles, rose uglyly into the air.

Then with a "click", a hideous and terrifying hole was cracked from the bottom of the ship to the side of the ship, and the hull structure broke in the air.

Then when the hull hit the water, the banging gunboats had broken into two pieces in front and back, and were sank rapidly after each being frantically filled with water.

In the blink of an eye, four Mongolian gunboats were inexplicably sunk.

...At this time, on Mahaye's flagship, the gunners and sailors who were originally happy and smiling all seemed to be grabbed by someone's crotch, and their faces were red with fear, standing there as if they were standing there as if they were holding their crotch.

But at this time, Mahaye suddenly thought of something.

There was no white smoke coming from the city gate in the distance, and there was no sign of artillery fire on the land. There was no flash of fire from the three gunboats in the opposite harbor.

In this way, our four warships were not sunk because of the enemy's artillery.

As for what that thing is, it is not difficult for Mahaye to guess now.

Only the gunboats that rushed to the forefront in the fleet were the first to be affected.

And when the last ship sank, half of the hull was even raised by a huge explosion at the bottom of the sea.

That means that the Song army arranged ambush like mines used in land combat under this sea surface! Of course, this kind of mine is not as used on the ground.

Because the sea water is denser than air, in order to play a destructive role normally in the sea water, the power of this thunder is so great that it makes people outrageous... At this time, Mahaye thought that if there were such landmines under the sea surface ahead, whoever rushed over would die now! "Turn the sail immediately and stop moving forward!"

At this time, Mahaye hurriedly gave an order, and then the messenger on his flagship began to whine the ox horn, and at this moment all the Mongolian warships braked suddenly.

They also understood the meaning of the navy general Mahaye. Many warships even threw the anchor from the stern because they could not turn in time. After turning, they hurriedly cut off the anchor cable.

The entire fleet adjusted the direction of the sails and retreated slightly under the influence of the north wind... During this period, there was still a warship that was too far ahead when turning. Under the terrifying gaze of all the sailors of the Mongolian fleet, a terrifying hole was blown up on the port side.

Then the warship rushed into the water wildly, but couldn't stop turning over.

The bottom of the ship covered with algae was overturned to the sea, like a dead fish with a belly facing upwards... Needless to say, the sailors and gunners on the ship were all finished.

Seeing that the fifth boat began to sink slowly, Mahaye gritted his teeth and stomped his feet, and he was still puzzled in his heart: Since there is this thing under the water, how could they be fine when several of the Song army's gunboats drove over?

...Now on the Song army's steam gunboat in the harbor, the artillery is preparing for the first round of volleys.
