The trebuchet, which originated in China very early, uses the lever type in principle, and there are mainly two types of lever trebuchets in the military service in the Middle Ages. One is a towed trebuchet, which mainly works by using human power to pull a rope to provide power; The other is a counterweight trebuchet, which uses counterweights to provide power.

The towed trebuchet is an ancient and simple trebuchet design, and the blueprint given by Hosokawa Miracle Maru is this weapon.

"Miracle Pill, where did you get this?" Hosokawa Senomaru looked at the cursive drawing paper on it, and his hands trembled slightly with excitement. Although the Western cannon is powerful, the angle is limited, and the biggest advantage of the trebuchet is that it can cross the city wall and strike the city.

"I got it from a Maori family!" Miracle Pill smiled slyly, but did not explain how it came about, it seems that it was an improper means.

"Good! Yuan Zheng! Can you see if you can make it? Clever Pill didn't ask much, and handed this ancient book to Asai Motomasa casually.

"Hmm... Lord, with this structural diagram, there must not be any big problems. Motomasa Asai took a closer look at this trebuchet and had a certain spectrum in his heart.

This trebuchet is relatively simple, consisting of a triangular fixed base, a very long movable beam and a swivel connecting structure. One end of the beam is a mesh or spoon-shaped accommodating body to hold the projectile, and the other end is a rope that is pulled down to get enough force to launch the projectile.

But even such a simple trebuchet is simply the difficulty of a missile series for a Japanese company with poor materials and scarce knowledge, and a counterweight trebuchet is even more difficult than a nuclear weapon.

In fact, the towed trebuchet does not need too professional engineers, and its main difficulty lies in the metal connection of the fixed node, and the length of the long end and the short end.

In general, the ratio of the long end to the short end is between 5:1 or 6:1, and if you are throwing heavier objects, this ratio is reduced to between 4:1 and 3:1. At the end of the short end there are 40-125 ropes fixed for 40-250 people to pull the ropes to operate the trebuchet, depending on the weight of the projectile.

The trebuchet that the Hosokawa family was going to build was naturally selected for the smallest 40-person traction, and its projectiles were roasted (the Mori family used pebbles), which was small but very lethal.

"Very good, then let's go down and make it!" Smart Pill nodded, he knew that although there was a design drawing, it was actually difficult to operate.

This trebuchet has a range of 78-125 meters and can shoot objects between 1-50 kilograms, but it has a fatal flaw, that is, each person has different swing power, resulting in an extremely poor accuracy, which belongs to the kind of level that says to hit you in the right eye, but not to hit the left foot of another person 10 meters away next to you.

"Yes!" Asai Motomasa is a low leader, and although this trebuchet has obvious defects, its advantages are also quite good. First of all, wood can be taken locally, easy to build, in addition, the construction speed is also fast, and its firing speed is also fast, since the accuracy is not good, then rely on the number to win, and the iron cannon similar to the operation.

"Ladies and gentlemen, in the past few days of building trebuchets, we have built a defensive line at these Sannomaru to prevent the enemy from coming to destroy them!" Smart Pill set the tone for a protracted battle, and everyone lowered their orders one after another.

"Also... Yuan Zheng sent someone to report to his father about the situation here, especially the tactical arrangements for a protracted war. "Clever Pill added another sentence.

"Yes!" Motomasa Asai respectfully received the order.

The battle situation at the front was quickly transmitted back to the Chinese army's big tent, and Hosokawa Nobumoto affirmed this tactic, and sent Mibuchi Fujiei and a thousand iron artillery teams of Zhezhi Kiyohiro to increase it.

With the affirmation of the new force and the lord, the former army officers and soldiers suddenly boiled with enthusiasm, and erected horse fences one by one overnight, becoming a simple line of defense to isolate the winding mountain road.

Just as the Hosokawa army was in full swing, the news came back to the guard general Miki Naogo, and it was already early the next morning.

"What? The Hosokawa army did not continue the offensive again? Instead build defenses on the spot? Miki Naogo blinked strangely, not knowing what kind of medicine was sold in the hosokawa family's gourd.

"Exactly! Miki-sama, go and have a look! Harumasa Minohe said, pointing outside.

"Hmm." Miki Naogo stood up, walked slowly out of the hall, and walked down the corridor to the observation tower on the top of the castle tower.

"It's—" It's just been the night, just an extra row of defensive fences.

"This should be just a temporary rest, pass on the order, pay close attention to the movements of the enemy army everywhere, and be sure to guard it strictly! Especially pay attention to the whereabouts of ninjas! I let them sneak in last time, that stupid guy Kato Duanzo! Miki Naogo observed for a while, disapproving, and now he really doesn't see anything unusual at all.

"Yes!" Harumasa Mitsunohe hurriedly lowered the leader's order.

"Also... Where did that guy go to Danzo Kato? It's been so many days and no news. Speaking of this ninja, Miki Naogo frowned, Duan Zang is a little arrogant and arrogant, and often goes his own way, even Iwaki Jiro, the leader of the Tsugawa ninjas, he doesn't pay attention to it.

"Uh... I don't know..."Harumasa Minohe also shook his head, no matter what action this ninja participated in, he never told him. It's good now, but the ninjas under him in the city are now leaderless, and they don't obey the orders of Naoxiang, which makes them very embarrassed.

That's it... Ten days and half a month passed, and Sannomaru, who was watching Hosokawa Smart Maru, slowly bulged up like a balloon. During this period, it naturally did not escape the eyes of the Tsukawa family, and it also counterattacked several times during the period, but the Hosokawa army relied on the horse fence and the iron cannon hit it in three stages, and it was baked and bombed, so that the Tsukawa army could not break through.

This is actually because the Tsugawa family did not do their best, although the method of soil attack is good, but there is also a limit, the current height is still less than halfway up the mountain, but obviously it can not be raised.

It's not that it can't be lifted, but it's more laborious than before, and on the side of Mt. Atsu-Shiga, a large pit dug out by the Hosokawa family is one after another, and the soil inside is filled with Sannomaru. These fills cannot be filled endlessly, each layer has to be constantly tamped, and when the thickness of the soil reaches a certain level, it is easy to sink in water.

But... This height... Enough is enough.

Today, Hosokawa Senchomaru is wearing heavy armor, sitting down on the BMW Liangju "Shower", the front row is a large phalanx with swords and armor, and the back row is the Eight Gate National Collapse, and there are twelve trebuchets in the last row.

I saw Hosokawa Smart Pill slowly pull out the sword on his waist and point to the winding mountain road opposite.
