A Yuan warship broke off the steel monster ship, and some Yuan soldiers jumped onto the monster ship and wanted to kill it inside, but they were surprised to find that there was not even a gap in the body of the monster ship.

The strange ship continued to rush forward, crashing into another Yuan warship, and the fierce impact made the Yuan soldiers who jumped onto the strange ship unsteady on their feet, and they all fell into the river.

"Marshal, please change ships for the time being." Adjutant General Liu Chen noticed that something was wrong and said to Zhang Hongfan.

"Since I entered the army, I have never avoided the enemy's edge, and now I have left the handsome ship with a slight setback, and the army's spirit is bound to be shaken, and the war cannot be done." Zhang Hongfan shook his head and refused, his eyes still fixed on the strange ship.

The strange ship suddenly turned around and collided with a Yuan warship in the other direction, and after sinking the Yuan warship, it did not continue to hit the next Yuan warship as it did just now, but stepped back and pushed a Yuan warship that had squeezed up to the side with its square stern.

At this time, Zhang Hongfan saw that a circular hole suddenly appeared on the side of the hull of this strange ship, and a large cloud of black liquid poured down from the hole and flowed into the river.

After the strange ship stopped for a moment, it suddenly began to rush forward again, but this time it did not ram the Yuan warship as it had just done, but quickly passed through the gap between the Yuan warships. The black liquid that flowed from the holes in the strange ship's hull spilled down, leaving a long black trail on the river.

Seeing the strange ships passing between the warships of the Yuan army at high speed, the soldiers of the Yuan army were all amazed.

Zhang Hongfan had been watching the movements of the strange ship, which soon circled from the left flank to the rear of the Yuan convoy array, where it traveled back and forth, spreading the black track between the Yuan warships. After going back and forth a few times, it circled from the rear of the Yuan fleet array to the right flank, where it circled.

When the strange ship finished turning around on the right flank and circled back to the front of the Yuan army's fleet array, Zhang Hongfan looked at the black oil it sprinkled on the river, and suddenly understood, and couldn't help but change his complexion.

"Spread out! Let all the boats disperse! He yelled.

The heralds immediately beat their drums and gave orders, but it was too late.

A man suddenly appeared on the strange ship.

Zhang Hongfan saw that it was a young man dressed in the costume of a Song scholar, he stood there, standing with his hands in his hands, and looked at Zhang Hongfan quietly.

"Quick! Kill him! Zhang Hongfan suddenly realized who this young man was, pointed at him and screamed.

When the surrounding soldiers heard his roar, most of them didn't react, only Liu Ying moved quickly, he was originally standing at the bow of the ship, as soon as Zhang Hongfan's voice fell, he had already opened his bow and shot an arrow at the young man on the strange boat.

His arrow can be said to have used all his strength, and in order to be able to kill the other party, he also used the "continuous arrow" stunt, after one arrow was shot, followed by four arrows, each shot at the young man's vital point, no matter how agile the young man was, he couldn't dodge.

But what surprised Liu Ying was that the other party had no intention of hiding at all.

Five sharp arrows were about to shoot the young man through, but he saw that an iron plate suddenly stood up at the young man's feet, and all the arrows were blocked, and then the iron plate quickly retracted.

"Alright, it's not too early, don't be cool there." Ye Chuchu's voice came, "Hurry up and get to work." ”

"All the oil is clean?" Sun Hui smiled and asked.

"As soon as I turned to the front, the oil ran out." Ye Chuchu smiled, "It's not that I'm criticizing you, when you first took math class, you definitely didn't listen to the lecture well, just now when you went around sprinkling oil in a circle, you ran a lot of wrong roads and wasted a lot of oil, I think if the oil catches up for a while, there will definitely be fish that slip through the net." ”

"Ran more wrongful way? Do I have one? Sun Hui made him a little embarrassed, he looked ahead, and sure enough, the oil slick on the surface of the river seemed to be a little less.

"Have you forgotten all about the 'postman problem' (the mathematical problem of connecting multiple points with non-repeating paths)?" Ye Chuchu's answer surprised Sun Hui, he had always been conceited of his knowledge, but he didn't expect Ye Chuchu to learn mathematics better than him.

"No, no, I just didn't think about it." Sun Hui smiled, "It's time to use it now." ”

"You save your energy, just light the fire and it's over, we just need to guard around and don't let the fish that slip through the net run away." Ye Chuchu said, "Besides, there are so many warships of the Song army, what are you doing idle?" Tell them to come up and work. ”

"If there's a fire here, they'll come up." Sun Hui said, "I'll go now." ”

"Well, go ahead. I'll wait for you. Ye Chuchu said in the iron boat, or it can be said that this iron boat is her.

Sun Hui took a deep breath, clenched his fists, and let out a loud shout, only hearing a "bang", his whole body was surrounded by orange-yellow flames.

Seeing that the young man on the strange boat had turned into a fire man, Liu Ying also understood who this person was, he was unwilling to fail like this, gritted his teeth, opened his bow and arrows again, and shot at the other party.

The other party still didn't dodge this time, and a sharp arrow roared and hit him, but as if shooting on a shadow, it passed directly through the flames and fell far into the river.

Sun Hui looked at the young man standing on the bow of the big ship, sneered, jumped up, landed on the wreckage of a Yuan army warship, and lightly touched the oil slick on the river with his foot.

The flames rose instantly, and the flames spread out from the central point of Sun Hui's location, quickly surrounding the entire Yuan army warship array, and the Yuan army warships ignited the fire one after another.

The fire of the Yuan army fleet seemed to be a signal, and there were bursts of low horns and dense drums on the river, and the Song army fleet, which had retreated, turned around and killed it again.

Seeing that his fleet had turned into a sea of fire, and countless soldiers who had fallen into the water were struggling and wailing in the flames, Zhang Hongfan's heart was like a knife for a while, and he fell down weakly, and lay down next to the railing of the shipbuilding.

Now he finally understands that the unseen legends of the Song people about Sun Hui are true. That man single-handedly defeated the Jin army and turned the tide of the tide, which is a real thing, just like now.

"Handsome! Let's go! It's too late! The subordinate general Liu Chen supported him and said to him eagerly.

"Let's go......" Zhang Hongfan looked at the subordinates and several dead guards on the ship's floor, "You all go, report the details to the Great Khan, please be careful with the ......"

After Zhang Hongfan finished speaking, he got up, returned to his seat, sat upright, and silently looked ahead.
