The Mongols also seemed to have expected that the "Island of No Return" would not take the initiative to attack and fight it at sea, so the day after sending a night scout and delivering a war letter, they began to launch an offensive against the "Island of No Return".

Small boats full of Mongolian warriors sailed ashore. With the sound of the horns on the battleships behind, these Mongolian warriors who had abandoned their boats and landed on the shore quickly formed a neat phalanx, with pikemen, sword and shield men, and archers arranged in layers and in an orderly manner.

On the dangerous pass that held the only passage to the interior of the "Island of No Return", Yan Chongtian and Yu Tianlai stood side by side, looking at the Mongolian army that finally set foot on the land of the "Island of No Return".

Yan Chongtian looked at it for a long time, and sighed: "I thought that the Mongols were only powerful in horse archery, but judging from this battle formation, I am afraid that their foot combat ability is not much worse." Yan has always been proud of the 3,000 warriors trained according to the art of war of Yue Wangye, but compared with the group of Mongolian warriors in front of him, he is only slightly superior. ”

Yu Tianlai smiled and said: "The Lord of Yandao doesn't have to grow the enemy's ambition to destroy his prestige. As far as the poor monk knew, there should not be too many Mongol troops who were so well-trained and skilled in foot combat. After Kublai Khan seized the throne of Khan, he was bent on implementing the policy of sinicization in Mongolia, imitating the political culture of our Han people, and employing many Han cultural and military officials.

The poor monk speculated that he should have considered that the Mongolian cavalry was good at field warfare but not good at attacking fortifications, so he was determined to develop the Mongolian soldiers' ability to fight on foot. It's just that he hasn't been on the throne for a few years, and I heard that the implementation of the Sinicization policy has been difficult due to the strong opposition of the Mongolian tribes and nobles, and I think that the innovation in the army should also make limited progress. ”

Yan Chongtian listened to Yu Tianlai's penetrating analysis, his expression relaxed slightly, and he sincerely admired: "This insight of the Zen master really makes Yan admire. ”

Yu Tianlai smiled and said a few words of humility, then glanced left and right without a trace, and then lowered his voice and asked, "I don't know how to prepare for that matter?"

Yan Chongtian's eyes flashed with a cold light, and he also lowered his voice and said, "It has been arranged according to our design, and my uncle and father are responsible for this matter." Although he is witty and unrestrained on weekdays, he will never be ambiguous in such major matters, and his martial arts are high, and his water nature is unparalleled in the world, and he is the most suitable person at that time. It's just that the Zen master thinks that news is credible?"

Yu Tianlai sighed slightly: "Although this news is strange, the poor monk thinks that its content is meticulous, and there should be no fraud." What's more, seeing that those Mongolian warriors did not carry siege equipment such as ladders in addition to their weapons, it seems that they want to attack this thick and towering pass under your feet in a conventional way, which can also confirm the authenticity of the news from the side. ”

Yan Chongtian nodded and said, "The Zen Master's analysis is really reasonable, so we will act according to the plan." ”

Yu Tianlai sighed: "It's just that in this way, the children of Guidao will have to pay some price, otherwise they will only be seen by the other party." ”

Yan Chongtian said angrily: "The soldiers are fierce and dangerous, how can there be immortals." Since the decision to return to Middle-earth to join the great cause of resisting Mongolia, everyone on the 'Island of No Return', including Yan, has already had the consciousness of giving up this life!"

At the same time, on the largest warship at sea, Bo Yan also had a low conversation with Xuzhuxi: "Brother Dao, do you think we can go down the 'Island of No Return' today?"

Xuzhenxi said with a smile: "Boyan Gongzi has always been strategizing, but at this moment, why does he seem to be a little lacking in confidence?"

Boyan smiled self-deprecatingly and said: "Although I have learned a lot of ways to use soldiers, this is the first time I have commanded a battle, and I am really worried that I will become the 'paper soldier' Zhao Kuo." ”

Xuzhuxi shook his head and said: "If the son is concerned, it will be chaotic, according to the poor way, as long as the two sharp weapons arranged by the son are launched, we will never be defeated in this battle." ”

Boyan obviously became more and more convinced of Xuzhuxi, and when he heard him say this, some waves in his heart calmed down. When he saw that the Mongol warriors had been sent out to battle on the shore, he raised his voice and ordered: "All ships dock, the artisan battalion is ready!"

The order was transmitted, and ten huge warships were launched together, slowly sailing towards the "island of no return". At the same time, some high-nosed and deep-eyed alien craftsmen hurried out of the cabin and came to the side of a huge thing on the deck covered with a green cloth curtain. These things were dismantled and secretly transported with the ship, and they took them a night to reassemble and fix them on the deck.

The craftsmen uncovered the green cloth with their hands and feet, revealing the huge and hideous tools of war underneath.

"Sure enough, it's a 'return cannon'!" Yu Tianlai's eyes were as sharp as lightning, and he had already seen things on the ship from a distance.

Yan Chongtian frowned and asked: "Zen master, the projection car is a device that I have in ancient times, although the power is not small, but there are always problems with the rate of fire, range and accuracy, this 'return cannon' made by Mongolia is also a kind of catapult, is it really so terrifying?"

"That's true," Yu Tianlai nodded seriously and replied, "As far as the poor monk knows, this 'return cannon' is a sharp weapon invented by two skilled craftsmen in the Western Regions. ”

While the two were talking, the Mongol warship was already anchored on the shore, and the "return gun" on the ship was ready to stop.

At the moment before the start of the war, Boyan completely regained his free and easy. He smiled at Xuzhenxi and said, "Today, let's test the power of the 'Huihui Cannon' made by those craftsmen from the Western Regions in actual combat? If there is still no situation, this is the weapon that we will use to break through the fortified city like Xiangyang when we attack the Song Dynasty in the future." ”

A heavy round stone projectile was loaded into a net pocket at the end of the slender arm of a "return cannon". An alien craftsman respectfully asked Boyan for instructions: "My lord, you are ready, can you start testing the cannon?"

Boyan looked at the towering pass at the top of a long ramp and built between two cliffs, a cold look appeared on his handsome face, and he said lightly: "Let's start!"

A large executioner with a flickering cold light fell, and a tenacious rope taut on the "return cannon" snapped. With a thunderclap-like bang, the huge battleship sank slightly, and the heavy counterweight box at the other end of the bullet arm fell sharply, driving the bullet arm to rise strongly, and the stone bullets in the net pocket whistled out, drawing a graceful arc in the air, and flying towards the pass on the high slope in the distance with the sound of rumbling wind and thunder.

"Boom!" The stone bomb landed on the ramp more than 20 paces away from the pass, and after the smooth and tamped hard road, mud and gravel flew everywhere, and a pit six or seven feet deep appeared on the ground.

All the people on the pass changed their faces, even Yan Chongtian, who had been mentally prepared, was no exception.

Yu Tianlai reminded on the side: "Lord Yandao, this stone projectile should be just an experiment, the Mongolian side will soon be able to adjust the firing range by increasing or decreasing the counterweight, and the next time will be all the 'return artillery' salvos, please make a decision quickly." ”

Yan Chongtian paused suddenly, and shouted: "Everyone withdraw from the pass and line up three hundred steps behind the pass to resist the enemy!"
