The engineering equipment is light, in fact, it is the engineer, the full name of the engineering soldier. It is a branch of the army established by Hosokawa Nobumoto to undertake the task of military engineering support, and the engineering unit has the ability to quickly carry out a variety of engineering operations and carry out certain combat tasks, and is the technical backbone of the army in carrying out engineering support, replacing the work of requisitioning civilian soldiers.

Because the people's combat effectiveness is extremely poor, if the war goes unwell, they will flee in large numbers, which greatly affects morale. The engineering corps is different, they were born in the military, kept in mind the "Hosokawa Military Law", accompanied the battle, opened roads in the mountains, and built bridges in the water.

The ten-sided ambush array came from their handwriting.

I saw that this siege battle also sent them up.

"Are you all ready?" Kawakatsuhide's expression was excited, after all, everyone wanted to go to the front line to fight, and they didn't want to shrink back as a sapper.

"Oh!" The Chuansheng engineers are also excited, this is a tough battle!

"Be quick! Above! Kawa Katsuhide gave a few more instructions, after all, it is a wartime operation, and it is very efficient.

Stomp Tread... The Chuan Sheng engineer began to pick up the guy in his hand and ran to the door.

First of all, there are nine people who each hold a small section of square wooden cushion block, and according to the distance measured by the tenth person with a wooden ruler, the base is fixed in turn!

Akai Tadashi and the others looked at their strange movements and said that they were attacking the city with a secret weapon, what are they doing? Even the nine households in the multi-door oars above peeked through the observation hole, wondering what they were doing below, drawing a circle and cursing themselves? Amusing!

Of course, since Hosokawa Jun had no intention of breaking the door, he would not throw stones for just ten people, after all, this stone is also limited and must be used on the blade. For example, smashing doorwood, or a large number of enemy troops.

After setting the spot, nine more people picked up a fist-sized, three-meter-long square wood and came to these nine points. With a gag sound, the square wood was connected to the cushion block, and it was tightly sealed, and it was impossible to see that these were originally two separate pieces of wood.

"Huh?" It was the first time he had seen it, but he knew that it was a carpenter's technical work to make furniture, but he didn't know how it worked.

This is the "mortise and tenon structure" in the hands of skilled craftsmen, which is the main structural mode of ancient buildings, furniture and other equipment, and is a combination of concave and convex parts on the two components.

The protruding part is called tenon (tenon), the concave part is called Mao (tenon), and the connection method of the sapper is called the combination of square timber T-shaped (mortise and tenon joint large in and small out).

As soon as this job is done, it becomes a three-row, three-column arrangement with the same spacing. Then the sappers were one meter and five meters high, crossed with straight materials, and the crossbar stubble was also a mortise and tenon structure, and finally became a "Tian" character.

"Huh?" The more people looked at it, the more confused they became, is this going to build something?

"Well, it's fast, keep going!" Kawakatsu nodded with satisfaction, about the same speed as his usual training.

Immediately afterwards, the sappers climbed up the pole like monkeys, using the crossbar at a distance of one meter and five as a foothold, and then set up a "field" character at three meters.

"Oh, I wanted to take a ladder to climb up." Seeing this, everyone couldn't help but think like this, after all, if you stand at three meters and add your height, you can almost reach the mouth of "Shiluo".

"Humph! Insect carving skills! The Hosokawa family is really stupid, it seems that it can save me from falling rocks, and the gun is lightly prepared! Jiuhe Shinaka disdained, it was not so easy to climb up from this mouth, as long as a group of guns was arranged, it was guaranteed to be guarded by one man.

"Yes!" Tsugawa Ashigaru surrounded the mouth of "Stone Fall", holding a spear and waiting, they were very confident, even if a bird flew in, it could instantly stab into a hornet's nest!

But... After waiting for a while, I saw a wooden ruler poking its head out.

"Attention! The enemy is coming! Let them have no return later! Nobunaka Kunohe said in a deep voice, and he himself stepped back, for fear of throwing something in.

However, he cautiously brought in a group of iron cannons and aimed them there. Two samurai were assigned to observe the observation holes on both sides, and if they found traces of explosives such as baking, spears and stones would be sacrificed together to ensure that they would suffer the consequences.

With a stabbing moment, the wooden ruler immediately retracted as if frightened.

"Five!" Suddenly, such a sentence was shouted from below, which made Tsugawa Ashigaru more sure that there would definitely be a No. 5 later.

Suddenly, the translucent "stone fall" was covered from below, and Tsugawa Ashigaru, who was on standby, was stunned for a moment, not understanding what this meant. Suddenly!

Knock knock... There was a sound of knocking, and everyone immediately became nervous, and they all lowered their bodies, ready to stab at any time.

"Steady! Steady! The enemy is coming up soon! "The two junior samurai had been observing the small hole next to them, and found that a large number of people had gathered on the wooden frame of the second step, busy with something, but they were not carrying explosives.

Knock knock... There was a little more tapping, but the sound faded away.

"Get on the scissor brace!" Akishi Kawakatsu saw that the top of the wooden frame had been completed, and used the roof to get the wooden plank stuck in the hole, which is called the template scaffolding support system in architecture.

And because the erection of scaffolding is in accordance with the same height, the same span is erected, the façade is a vertical rectangle, when reaching a certain height, the support effect is not good, from a mechanical point of view, the structure of the rectangle is not a static structure. So with the addition of a diagonal support, it becomes a triangle. The triangle has stability, that is, it is a statically determined structure, which is the scissor brace.

"Add a sweeping rod!" After completing the scissor support, Kawakatsu Xiu was still not at ease, and added another process.

The sweeping rod refers to a part of the scaffolding project, the sweeping rod is 200mm away from the ground, and the horizontal rod is connected to the root of the vertical pole. It is divided into longitudinal and transverse sweeping rods, which play a role in stabilizing scaffolding. The transverse sweeping rod is below the longitudinal sweeping rod, and the force is transmitted to the vertical rod and then to the foundation through the transverse sweeping rod to ensure the stability of the center of gravity.

After a period of busy work, the template support system completely blocked the "stone fall" mouth.

"Damn! Smash it open for me! Fast! "Nobunaka Kunohe took a group of people, and he smashed and stomped on this plank, he knew that he had been fooled, and the purpose of the Hosokawa army was to block it.

Unfortunately, this plank is thickened, and this support system can support more than a ton of load, no matter how they smash it, it just doesn't move.

"Haha... Okay, so you can bang on the door with peace of mind! Akai laughed, and now no one could stop them.

"But... There's a question, how do we carry the bars of the door with your rows of horizontal and vertical square logs? When Akai Tadashi and the others lifted the door log, they suddenly found that these so-called sweeping rods were seriously hindering their running.
