The method of retreating and impacting that Sun Hui said was not something he came up with with a pat on his head, but came from real history.

Sun Hui told the girls that when the Spaniards attacked Tenochtitlan, the capital of the Aztec Empire, they were hit hard by the Aztec canoe troops in the battle for the towns near the lake, and suffered heavy casualties. Because the Aztec canoes roared when attacking, they could land on any convenient shore and quickly leave when retreating, and the Spanish cavalry could do nothing to them. For this reason, Cortés, the commander of the Spaniards, built 13 brigs and entered the lake area to ram the Aztec canoes in order to gain control of the lake area, but the Aztecs made many hidden wooden stakes in the lake, so that the Spanish sailing ships ran aground and then launched an attack, which once caused serious losses to Cortés' sailing troops, and several sailing ships were destroyed or captured, until later the Spaniards accidentally discovered this way of retreating and ramming with a sailboat to hit the stakes, so that most of the wooden stakes painstakingly set by the Aztecs failed, Only then did they finally defeat the Aztec canoe forces and win the right to control the water in the Great Lakes.

After listening to Sun Hui's explanation, Ye Chuchu understood, just as she was about to manipulate the iron boat to act, another boulder flew over and entered the water not far from the iron boat, and the waves hit the hull of the boat, and the sound made scared Sun Hui.

"Let's open a road out first, lead to those stone platforms, and kill the stone throwers on them." Ye Chuchu looked at the porthole, observed the situation, and said.

"Yes, although our ship is made of iron, it is quite bearable to smash that rock." Wang Linlin said.

"Okay, that's it, Chu Chu, you knock the stake away, open a way out, and let the boat behind come over." Sun Hui said, "When I get to the stone platform, I'll go up and kill them directly." ”

Ye Chuchu nodded, first steered the iron ship to turn, came to the flagship of the Song army's fleet, informed Li Jin, the commander of the fleet, of the method of hitting the wooden stake and the battle plan, and then turned the bow of the ship and hit the stake area at full speed.

Sun Hui looked out of the observation window at the bow of the ship, and saw that the iron boat was like a rhinoceros, crashing straight into the wooden stake.

The wooden stakes laid by the Yuan soldiers were extremely strong, but Ye Chuchu's iron ship originally had an angle of attack, coupled with the strong hull and fast speed, under the collision, the wooden stakes broke one after another, making an explosion-like sound.

"It's easy." Ye Chuchu smiled, manipulated the iron boat to retreat slightly, and then rushed again, knocking down all the wooden stakes in front of him again.

Seeing that the iron ship knocked down a large piece of wooden stakes one after another and came straight to the stone platform, the soldiers of the Yuan army on the stone platform were all busy, and successively used stone cannons to throw stones at the iron ship, but the iron boat was too fast to hit the stones thrown by the Yuan army.

Soon, the ten Song warships behind also rushed up, according to Sun Hui's backward ramming tactics, ramming the wooden piles, the hulls of these warships were lighter, and the impact results were not as good as the iron ships, but they also knocked down a large number of wooden stakes, and soon, a channel was opened.

"It's up to you." Ye Chuchu said, manipulating the iron boat to rampage all the way and came to a stone platform.

Sun Hui asked Ye Chuchu to send himself to the deck, at this time the position of the iron ship was the dead angle of the stone cannon fired on the stone platform, and the stones thrown by the Yuan army could not hit the iron ship, and the Yuan army on the platform saw that Sun Hui appeared on the deck of the iron ship, and immediately shot at him with crossbow arrows, and the arrows rained down for a while.

Sun Hui shouted, and his whole body instantly turned into raging flames, forming a wall of fire, surrounding his whole person, and the arrows shot by the Yuan army shot into the wall of fire, the shaft of the arrow instantly turned into ashes, and the arrow shaft quickly melted into molten iron.

"Don't burn my ship to the ground." Ye Chuchu shouted below.

"Don't worry, I've got it." Sun Hui smiled and jumped up suddenly.

Ye Chuchu and the girls saw Sun Hui fly up from the deck of the iron ship like a meteor, pull out a long parabola in the air, and then fall onto the stone platform.

It was as if a bombshell had fallen on the stone platform, only to see a flash of red light on the stone platform, and then a large mass of flames and smoke rose up, and the soldiers of the Yuan army who were dancing and dancing all over the fire could be seen in the smoke, and the stone cannons on the stone platform were all shattered and fell into the river.

"Brother Sun has become a cannonball this time." Wang Linlin saw this spectacular scene and stuck out her tongue naughtily.

"The key is that this 'cannonball' can be used continuously." Ye Chuchu said with a smile.

As soon as she finished speaking, she saw another "fire meteor" fly up from the stone platform, pull out a long parabola, and fall towards another stone platform, and then the same "explosion" occurred on this stone platform.

After a while, the Yuan army on the six stone platforms in the wooden pile area was completely annihilated by Sun Hui.

After eliminating the threat of stone cannons on the stone platform, Sun Hui returned to the iron boat, Ye Chuchu continued to manipulate the iron boat to hit the wooden piles, and the Song army warships behind also followed to help, and soon, most of the wooden stakes in the wooden pile area did not work.

"It's quite easy to pass the White River Estuary." Ye Chuchu watched the Song army warship behind him pass through the stake area, and said to Sun Hui with a smile, "I don't know what will happen in the next level." ”

"Isn't the next level called the Ghost Gate?" Wang Linlin said, "I'm afraid they will set up a lot of scary things, right?" ”

"Hehe, that ghost gate pass is a place name, because of the treacherous terrain, so it was named, and it used to be called Tianmen Pass or Yin Yang Pass." Sun Hui said, "There are probably more dangerous shoals there, the current is also rapid, and there are reefs if you can't get it, so we have to be careful, as for the artificial obstacles, they are probably wooden piles and stone platforms, so don't worry." ”

"It's not far ahead, I'll go over and have a look." Xiao Tiantian said, then left the iron boat, disappeared into the river, and disappeared.

Sun Hui ordered the fleet to slow down and move forward slowly, so as to wait for Xiao Tiantian's reconnaissance to return, and after a while, Xiao Tiantian returned.

"There are no wooden stakes, no rapids, and the water is a little sharp, but there are a lot of reefs, and they are all very sharp, and the wooden boats will sink when they hit it." Xiao Tiantian said, "Then there will be a big whirlpool in Jiangxin from time to time, and it is easy to get a small boat into it." ”

"Is there a setup for the Yuan army there?" Ye Chuchu listened to Xiao Tiantian's report, thought about it, and asked.

"There is a water village and a land village, which are horns of each other, but there is not a single boat in the water village, and I don't know where to go." Xiao Tiantian replied.

"Maybe they think those reefs and whirlpools are enough to deal with us, right?" Wang Linlin said, "That's why I deliberately didn't let the warship here." ”
