After one Yuan soldier poked a long pole into the copper pipe, another Yuan soldier inserted a black oil rope-like object into the back end of the copper pipe, then raised a torch and lit the thing.

Seeing that all the soldiers of the Yuan army were all bent down and covering their ears, Jiang Cai couldn't help but be surprised.

Suddenly, a red light flashed from the mouth of the copper pipe, and then a large cloud of black smoke erupted, and a black ball flew straight towards the Song army vehicle and ship on the opposite side with a thunderous sound.

The bow of the Song army's chariot ship was hit by a black ball, and it shattered when it landed, and then the roar continued, and the copper pipes on several other Yuan army war ships also shot black balls, due to the close distance, almost all of these balls hit the square bow of the Song army's chariot ship on the opposite side, and the bow was shattered.

Immediately afterwards, another cannon on the Yuan army's warship also began to fire, and another round of serial bombardment broke through the cannonballs of many Song army vehicles and ships, and many people were killed and wounded. But what surprised Liu Chuan was that those vines grew rapidly, filling and wrapping the wounds from the Yuan army's cannons!

Although the vines were trying to repair the places where the Song army vehicles and ships were damaged by the Yuan army's cannons, there were still five Song army vehicles and ships that were too injured and began to sink.

The sunken Song army vehicles and ships caused a hole in the front of the Song army's originally neat ship formation, but the Song army warships behind quickly rushed up, filling the gap in the formation, and protruding bronze angles from under the bow, and the vines also stretched out, connecting them with other Song army warships.

Seeing this scene, Liu Quan's heart sank suddenly.

The Yuan artillery continued to bombard, sinking two more Song army vehicles and ships, but soon their positions were filled by the Song army warships behind, and some Song army warships also discovered the threat of these Yuan army warships with cannons, and used stone throwers to attack these Yuan army gunboats. Huge boulders swept through the sky and smashed straight towards the Yuan gunboats.

The gunboats of the Yuan army were all anchored at this time, and after being attacked by the stone cannons of the Song army, it was difficult to dodge, and a gunboat first hit a boulder in the fort and was smashed, and the cannon rolled off the gun carriage, crushing several Yuan soldiers, and then another boulder hit the surface of the ship, directly smashed through the ship's board, and entered the cabin. The gunboat's hull shook and began to tilt to one side. At this time, another fireball fired by the Song warship flew over, and just flew into the cabin through the hole in the ship's board smashed by the boulder, probably leading the gunpowder accumulated in the cabin, only to see that the gunboat's whole body suddenly burst out with a large ball of fire and black smoke, and then it shattered with a "bang".

Seeing that this gunboat caught fire and exploded, the Yuan officers and soldiers on the remaining eleven gunboats were all shocked, and immediately turned to flee for their lives.

"It seems that Jia Xianggong here can handle it completely, and he doesn't need me." On the tower of the catamaran giant ship of the Song army, which is the flagship of the whole army, Sun Hui saw the collapse of the Yuan army's artillery fleet, and said to Jia Yidao beside him with a smile.

"If it weren't for the guidance of the Immortal Master, there would never be such a big victory today." Jia Rudao bowed to Sun Hui.

"The public order and the soldiers use their lives is really pleasant." Sun Hui smiled and patted Jia Yidao's shoulder, "In this way, Xianggong will continue to attack here as originally planned, after destroying Liu Quanshui's army, don't stop, go straight to Xiangyang through Badger Beach to meet General Lu." By land, as long as the Yuan army is dragged and not allowed to leave Lumen Fort. ”

"Obey the Immortal Master's decree." Jia Rudao hurriedly answered.

"Linlin, are you okay?" Sun Hui turned his head and asked, although Wang Linlin was not by his side.

"It's okay, Brother Sun, I can handle it." Wang Linlin's voice came from the hull of the ship.

"Be careful of those two guys in the sky, they may fly down to attack Jia Xianggong, and then it's all up to you." Sun Hui looked at Jia Nidao and said, "Remember not to show yourself and hide in wood or rattan to fight them." ”

"Understood, Brother Sun, don't worry! Mr. Jia handed it over to me! Wang Linlin replied mischievously.

Hearing Wang Linlin call herself "Mr. Jia", Jia seemed to say that somehow, he actually had a feeling of flattery, "There is Lao Wang Xiangu." ”

"Then let's say goodbye, I'll go to support the pontoon, and we'll see you in Xiangyang City." Sun Hui arched his hand to Jia Rudao as he spoke, turned around and walked quickly to a cabin.

In the huge cabin, Ye Chuchu's iron ship was parked.

Jia Rudao and several officials also entered the cabin, and when they saw Sun Hui jumping lightly, they jumped on the iron boat, and then disappeared into the iron boat, and several people bowed to the iron boat again.

"Linlin, put us down." Ye Chuchu looked at Jia Yidao and those pedantic officials through the porthole with some amusement, and shouted.

"Okay! Sister Chu Chu! Start now, dive urgently! Wang Linlin said, first rolled up the iron boat with vines, then opened the board under the iron hull, and then loosened the vines, and the iron boat fell into the water under the stunned gaze of Jia Yidao and others.

Sun Hui was about to remind Ye Chuchu to close the porthole, but he didn't expect a transparent glass window-like baffle to rise inside the porthole, blocking all the water from the outside.

"Where's the glass?" Sun Hui was stunned for a moment, and then asked.

"It's crystals, stupid." Ye Chuchu smiled playfully, "I heard about your idea of a submarine, it was Lili who found a lot of crystal crystals before leaving, came back, turned them into plates, and I set them all in. ”

"Hehe, then the windows of our ship are luxurious and luxurious." Sun Hui said with a smile.

Indeed, whether it is ancient or modern, to be able to use such a large crystal plate to make a window has to be something that only a local tyrant can do.

"And the periscope, which is also a crystal lens." Ye Chuchu smiled, "You can take a look at the situation above in a while." ”

Ye Chuchu said, waved his hand, and there was a sound of bubbles around the iron boat, and Sun Hui knew that it was Ye Chuchu who was using the principle of "water intake and drainage" to make the iron boat dive quickly.

After diving to a certain depth, Ye Chuchu manipulated the iron boat to quickly sail forward underwater.

In order to let Sun Hui understand the surrounding situation, Ye Chuchu also opened a skylight on the top of the cabin, so that Sun Hui could see the situation above when he looked up.

The iron ship swept the bottom of one Song warship after another at high speed, and soon came to the bottom of the battlefield.
