In terms of appearance and ease of transformation, it was the first choice, but Zhao Yu did not choose it. This is because warships are platforms used to fight, and they also need to carry weapons.

During this period, in addition to continuing to use the ancient way of engaging ships, more attention was paid to the use of projectile weapons. Under normal circumstances, the two sides fought from a certain distance, so projectile weapons played an increasingly important role in naval warfare. There is a saying that in naval battles, 'the bow and arrow are the first, the hook and gun are second, and the hand knife is secondary'. Due to the development of firearms, weapons such as rockets and artillery have also attracted special attention in naval warfare.

Of course, the application of rockets and artillery in the Song and Yuan dynasties was still in its earliest stage. A rocket is nothing more than a cartridge tied to an arrow, ignited and then fired with a crossbow to increase its range. And the cannon is not a metal barreled gun in the modern sense, but a powder bag fired by a catapult. However, because this kind of weapon is not only a projectile weapon, but also has the nature of a fire attack, it can destroy the enemy ship while killing and injuring the enemy, and it has still attracted the attention of all sides.

In order to be able to gain an advantage in naval battles, Zhao Yu had already 'invented' the ballista and used it in actual combat, and achieved good results. This solves the problem of the need for long-range high-power weapons due to the lack of artillery. However, the ballista is dozens of times heavier than the bow and arrow, and the space required is much larger, and the shooter who operates the ballista also needs to be completed by multiple people.

In addition, in addition to long-range weapons, the turtle ship also has a special move, which is to rely on the angle of attack on the bow to hit the hull of the enemy ship under the waterline, causing the enemy ship to enter the water and sink. In order to get the maximum impact, in addition to the speed of the ship, it must also have a large volume, otherwise after the collision, I don't know who it is? And the same end is not the result that Zhao Yu wants. These fatal flaws forced it to be out.

Another characteristic of using warships as carriers for water warfare is that warships must adjust the allocation of firepower and forces at any time according to the specific conditions of the battlefield. This requires it to have good mobility and quickly divide and merge and disperse in order to gain the initiative on the battlefield. On the contrary, if the warship loses its mobility, it will be difficult to attack and defend, and it will become a fixed target for the enemy's wanton attack. Thus losing the initiative on the battlefield.

The stern is powered by oars and oars, and it is flexible and flexible. However, the sea ship is large, so it is mainly powered by sails, so it is obviously affected by the climate, mainly the wind. In the case of a favorable wind, the naval warship can sail freely, and can ride the wind to smash the enemy's formation, and try to make use of the influence of the wind to turn it into its own advantage. Similarly. If there is a headwind, it will be difficult to maneuver and be beaten passively. Turtle ships, on the other hand, are based on surprise attacks as the main tactical choice, and good maneuverability is a must. It is obvious that sea vessels are not up to the task.

In this way, the multi-oared ship became the last choice, although its maneuverability was not as good as that of the ship, but its body was eight feet three feet long, two feet wide, and the load was up to 800 materials, and it could carry 200 soldiers. It can fully meet the requirements of carrying ballistas and soldiers. And its large size, combined with the angle of attack, can not only damage the enemy ship in the impact. and to ensure their own safety; As the name suggests, the multi-oared boat is to paddle the water to drive the ship to sail, and it uses forty-two oars, which can ensure that it can have high speed, good maneuverability, and the addition of mast sails during the transformation, which also has the ability to sail by the wind......

"This may be able to hold Qiongzhou!" Zhao Hao finalized the transformation plan. It can be regarded as letting go of a thing that has been bothering him for a long time, and muttered with a sigh of relief, and a picture of a sea battle appeared in his mind.

In the wide sea in the strait, the two armies faced each other, and our army first sent rocket boats to carry out strikes from a long distance, under the bombardment of rockets flying all over the sky. The enemy ships were either hit and caught fire, or tried to dodge, and collided with each other in the confusion, causing great losses; After the rocket attack is completed, the enemy regroups and wants to attack again. The turtle ships lurking in the shadows launched a surprise attack, firing ballistas from medium and long ranges, killing and wounding the sailors of the enemy ships and destroying their mast sails.

Although the enemy ships attacked the turtle ship with stone throwers and crossbows, the iron armor on its back provided it with good protection and could not inflict fatal damage on our side. After the two sides approached, the turtle boat turned to ram the enemy ship using the angle of attack. The enemy soldiers, on the other hand, wanted to engage in close combat, and when they managed to jump onto the back of the turtle boat, they found that the iron spikes on it had become a new nightmare, and they were either stabbed to death or did not dare to move again. Those who were lucky enough to climb the side of the ship were hit by arrows or spears fired by the soldiers in the turtle boat, and they could not escape their death.

At this time, our naval fleet composed of large warships launched a final attack, crushing the enemy's small ships with the overwhelming momentum of Mount Tai, pinching the enemy's main warships, and at the same time continuing to kill and wound the enemy soldiers on the enemy ships with equipped ballistas, covering our soldiers in broadside battles, killing and wounding enemy crews, capturing enemy ships, and ending the battle.

Of course, this ideal situation can only be achieved if the enemy has equal strength, or if the enemy has a slight advantage. However, if the enemy has an absolute superiority in strength or a situation in which the enemy attacks from multiple directions, I am afraid that relying on the strength of one's own naval army will inevitably be overstretched and it will be difficult to realize what one wants; after all, many ants can bite the elephant to death, and then it will be difficult to avoid anti-landing operations.

"The enemy forces forced landing, how should I defend it?" Zhao Hao, who had just been happy for a moment, thought of this question and was worried again, what else could he use besides turtle boats, ballistas and rockets, and he fell into hard thought again. He felt like he was in the eye of the storm, and although he had temporarily escaped the raging wind and waves, he was surrounded by surging waves, and if he was not careful, he would be thrown into it again, and he had to be careful to avoid it, or he could only meet it.

"Your Highness, Deputy Envoy Pan is going to set sail with the fleet tonight and escort the last batch of supplies to Qiongzhou, he has come to resign, and at the same time ask His Highness what else to explain." At this moment, a little yellow door whispered a few words in Wang De's ear, and he came over again to pray.

"This king has nothing to do, just act according to the predetermined plan, I still have things to think about, so I don't see him." Zhao Yu listened and saw that it was past noon, frowned and said, obviously a little dissatisfied with being interrupted in his train of thought.

"Okay, the little one will tell Deputy Envoy Pan!" Wang De said with a smile and stepped back and went out.

"Wait, order Deputy Envoy Pan to cancel all sailing plans, and order all ships anchored in the outer harbor to enter the inner harbor, and send a naval army to patrol the outer sea, and order all the ships left in the outer sea to return to the port before sunset!" As soon as Wang De's feet crossed the threshold, he heard the rapid shouts of His Highness...... (To be continued.) )
