At this time, there was still a fierce battle on the water, and under the light of the fire, Sun Hui could see through the crystal porthole of the iron ship that the water was full of broken wood chips and the wreckage of the ship's hull, as well as a mutilated corpse and severed limbs floating in it.

A huge fire suddenly flashed on the surface of the water, and then the water waves surged, and countless pieces of wood entered the water, followed by the charred corpses of many soldiers, one of which somehow rushed to the porthole of the iron ship, and the charred half of the face shook in front of the crystal window, which was extremely terrifying, and scared Sun Hui and Ye Chuchu.

"The Yuan Army's artillery fleet doesn't look good." Ye Chuchu looked up at the water above his head and said to Sun Hui.

"Their cannons are powerful, they just don't use them right." Sun Hui said, "It doesn't have to be in water battles, but it can be more powerful in field battles or sieges on land." ”

"That's why you didn't let me put a cannon on this iron ship?" Ye Chuchu asked curiously.

"Yes. You see the cannons of the Yuan army, which are already very advanced in this era, can only be loaded with two guns on a large ship, and the ship has to be anchored and fixed before it can be launched, and the salvo firepower formed by the twelve ships is still limited, and the Song army has a big stone and fireball, they can't run away, so they are all reimbursed. Sun Hui nodded with a smile, "Our iron ship is not big, and it doesn't make much sense to install one or two ancient artillery, so it's better to go up and hit it directly." ”

"Then you're not going to build a Urban cannon?" Ye Chuchu asked.

"No, the cannon still has to be built, but not like the Ottomans." Sun Hui replied.

"I thought I could save myself." Ye Chuchu smiled.

The iron ship continued to move underwater, and soon rushed across the battlefield to the bottom of the Yuan fleet.

"Do you want to do it and then leave?" Ye Chuchu said, "Help that guy Jia Rudao save some trouble." ”

"If only we could know which ship is Liu Quan's ship." Sun Hui looked at the huge black shadows at the bottom of the boat overhead, and said, "If you fight all, there are too many boats for them, and they will delay time, for fear that something will happen to the pontoon bridge." ”

"Normally, his ship would be the biggest." Ye Chuchu looked at the skylight and said.

"Then we'll get rid of the biggest boat and we'll go." Sun Hui said.

"Okay." Ye Chuchu said, observing the shadows of the boats.

"There." She quickly spotted her target and steered the iron ship towards it.

"It's in the middle of a lot of boats, and it doesn't seem to be easy to hit." Sun Hui visually measured the position and angle of the target, and found that this Yuan army giant ship was located in the middle of many Yuan army warships, and with the current position of the iron ship, it was impossible to carry out the impact.

Ye Chuchu slowed down the speed of the iron ship, looked at the target, frowned, and after thinking for a while, he quickly calculated it.

"There's a way." As she spoke, she steered the iron ship backwards and dived.

Soon, the iron ship retreated to a position almost to the bottom of the river, Ye Chuchu let the stern of the iron ship sink, and the bow of the ship was cocked to the position of the target.

"This angle is okay, but the place where the opponent's underwater part can reach is still very small, our bow is thicker, and the angle of attack is below, so it is still not easy to hit." Sun Hui said.

"Come to me." Ye Chuchu smiled slightly and beckoned to Sun Hui.

Sun Hui walked to her side a little strangely, she hugged him with a smile and lay down.

Sun Hui looked at her a little inexplicably, she naughtily blew into his face, and then Sun Hui suddenly heard a strange sound from the hull of the iron ship, and then the bulkheads on both sides began to compress to the middle.

Sun Hui understood what she was doing, and was so impressed for a while.

If Sun Hui were outside now, he would have seen that the original fusiform hull of the iron ship was elongating and tapering, the angle of attack in the bow had disappeared, and in its place was a sharper conical bow, and the whole iron ship would soon become a slender pointed torpedo.

At this time, in the iron ship, the bulkheads on both sides and up and down were almost attached to Sun Hui and Ye Chuchu.

"You're so smart, Chu Chu." Sun Hui kissed her cherry lips a little impulsively, but she turned her head away and avoided her, and his kiss fell on her cheek.

"Don't interfere with my work." Ye Chuchu winked at Sun Hui, "Launch!" She shouted.

As soon as she finished speaking, Sun Hui felt her body shake, and the torpedo-shaped iron boat rushed forward.

Sun Hui's head was above the skylight, he only saw the surrounding water, and understood that Ye Chuchu was manipulating the iron boat to rush towards the target at an unprecedented high speed.

"Liu Shuai, the Song army's ship formation is strong and difficult to break, and if it continues like this, our army's warships will be wiped out here." The adjutant general replied to Liu Quan.

"The warships of the Song army are all connected together, and now the wind direction is favorable to our army, as long as the wind sets fire, they can all be burned!" At this moment, Liu Cheng had lost his usual calmness, his eyes were wide open, and he roared again and again, as if he was crazy.

"Liu Shuai! The soldiers have already tried! But the fire has already been extinguished by the vines born by the demon! "Our army must retreat immediately!" Otherwise, everyone will die here! ”

"Yes! Handsome! Withdraw! The cronies and generals Sha Quan also persuaded.

Liu Cheng was just about to speak, when there was a sudden violent vibration under his feet, and the huge warship shook violently, and Liu Cheng and the others were unstable on their feet for a while, and they all fell.

Liu Cheng thought that his ship had hit the rocks, but he looked around and found that the warships around him were fine, only his own ship shook.

He suddenly had a bad thought in his heart, and his hands couldn't help but tremble.

"What's going on?" Answering the question in surprise, at this time, an officer of the Yuan army covered in water stumbled over, his face full of horror.

"What's going on?" Lost replied immediately. The officer panted and replied, "General, it's not good! The bottom of our ship gives ...... The ...... 'water monster' was broken with a giant horn arch! ”

As soon as the officer finished speaking, he heard a loud noise, and the huge Yuan army warship broke apart, and the building where Liu Cheng was located was instantly split into two, Liu Quan's feet were empty, and then the person fell.

The moment Liu Cheng fell into the icy river, he saw a huge "iron fish" coming out of the water, and the head of the iron fish was a huge drill bit, which was still spinning.

The moment Liu Cheng saw the iron fish, he understood why Sun Hui's iron boat never appeared.

The heavy armor dragged his body down rapidly, and he felt his surroundings grow darker and darker, like an endless abyss.
