Jiang Liu'er clearly saw that after the wooden block he threw accurately fell on the number "five" in the third row, there was a sudden loud sound of "creaking" machinery starting to run under the sandwich road, and then the small square below the number "five" suddenly fell rapidly, and the wooden block also fell into a black hole about four feet long and wide.

Then there was a very harsh-sounding "click", presumably the poor wood had been smashed to pieces.

Jiang Liu'er's heart jumped fiercely, and she couldn't help but swallow a mouthful of saliva.

It is conceivable that if you step on it this time, it is estimated that you will fall directly and be crushed into slag!

Because he noticed that although this small grid was only two feet, once the mechanism was activated, a circle of small grids near the small grid that he stepped on would fall instantly, enough to drop the entire body of four or five men of Jiang Liu'er's size!

The one foot of the Qin Dynasty is different from the later generations, one foot in the later generations is generally 33 centimeters, but the one foot of the Great Qin is 23 centimeters, so there is often a fallacy in later generations, many people do not believe it when it comes to the length of eight feet of the Qin army, because many people are measured by a foot in later generations, 33 times 8 is equal to 2 meters 64, generally speaking, there is no such tall person.

In fact, the height of a Qin soldier should be 23 times 8 equal to 1.84 meters, which can only be regarded as burly in contemporary terms, and it should be more reasonable.

And once the mechanism is touched here, the floor space that falls in an instant is enough for a meter, and it will fall directly no matter what.

That...... What if you jump out at the moment you are about to fall?

Jiang Liu'er instantly had a plan, but soon, he gave up this practice, and no matter whether he could have so much reflexes, even if he could get away with it at the moment when the small grid fell, and jump out of the trap, he would definitely have to step on other small squares, and he would not have any light skills, who knows what kind of mechanism arithmetic these other small squares have?

Looking at it, this dense arrow hole will not be used as an ornament!

At this moment, something that surprised Jiang Liuer appeared, those small lattice floors that had fallen instantly before were actually accompanied by a loud "click" sound at this time, and they actually resurfaced directly from the black hole, and what made him even more helpless and bitter was that the small lattice that turned up this time actually changed to a number!!

I was obviously touched by the number "five" before, but this time a number "three" directly floated up......

Faint! Can you still have fun......

Jiang Liu'er's heart suddenly sank, and her face became more and more solemn.

Anyway, at the moment, without the means to ensure security and the way to crack the mechanism, I will not take risks easily, after all, there is only one life, and death is death.

What he can do now is to continue to experiment to see if there is a good way to crack the mechanism, and he will not rashly risk himself unless he has to.

Outside the window, it was late at night, and in modern times, it was about eleven or twelve o'clock in the evening.

In an instant, another wooden block the size of a fist flew out of Jiang Liu'er's hand.

This time, Jiang Liu'er threw the small wooden block on the number "three" in the first row with ulterior motives, and as a result, something happened that made him very speechless:

The wooden block, which was only the size of a palm, after first touching the number "three" in the first row, bounced up directly, drew a strange arc in mid-air, and then gently landed on the number "nine" in the fourth row!

Immediately after, there was a harsh and disturbing "click" sound, and then something creepy happened, and the first thing to change was the first row.

As before, after the extremely elastic small wooden block quickly jumped away, the space near the small grid of the number "three" instantly fell into a large area of space, like a small black hole, which would mercilessly devour anyone or anything in an instant!

And the small wooden block that finally landed on the number "nine" in the fourth row also seemed to touch something terrible, and suddenly there was a very crisp and sharp sound of gold and iron and the sound of "clacking and clicking" and "clicking" of the mechanism activated by the walls on both sides, followed by a piercing "zizi" sound of the rope being tightened.

Jiang Liu'er seemed to remember something, and suddenly her face changed greatly!

This is...... Are you going to release the arrows???

It's obviously the sound of a bow being drawn!

Really!

As Jiang Liu'er expected, but half a breath, in the small holes arranged tightly on both sides like a beehive of insect eggs, the god of death and death came in an instant, mixed with the extremely piercing sound of "Xiu Xiu" breaking the sky, the arrows were like flying locusts, and countless dense sharp arrows were shot out quickly, and the formation, just like the spectacular and difficult to see directly with tens of thousands of crossbow soldiers and thousands of arrows, made people couldn't help but be shocked, and their hearts and galls were split!

"OMG!"

Jiang Liu'er was instantly stunned in the local area, what kind of work is this to shoot into a hedgehog!

If you stand in the middle, you will definitely be shot and there will be no scum left.

It is said that the Qin army has a strong bow and a hard crossbow, and the murderous spirit is awe-inspiring, and with the benefits of its bow and crossbow, it is enough to kill the Quartet and deter the world.

This time, I finally saw it......

Jiang Liu'er opened his mouth wide, his eyes were full of incredulity, he felt that his arms were weak, his thighs were fighting, the soles of his feet were numb, and even his buttocks, which had little to do with them, were like pins and needles, like mans on his back!

Those arrowholes that flaunt their might are like a group of self-confident and powerful mighty warriors, wantonly laughing at themselves, who do not know the height of the sky.

What Jiang Liu'er didn't expect was that what happened next made him stunned again!

Looking at the hedgehog-like arrow holes, the arrows shot from both sides of the mecca were directly like eyes, impartial, and shot straight into the arrow holes on the opposite wall that did not shoot arrows!

After a burst of shooting, there was not even a single arrow feather in the huge sandwich road!

Jiang Liu'er was completely shocked.

This is as if the person who designed the mechanism had premeditated, although the two sides have the same number of arrow holes, and they are perfectly symmetrical, but the number of arrows shot each time is only half of the arrow holes, and it is shot out of dislocation, for example, the arrow on the left wall is an odd number of arrow holes, then the wall on the right side of the road is used to put arrows with a double number of arrow holes, and the singular arrow holes are used to collect arrows, and vice versa.

In this way, while ensuring the lethality, the recycling of arrows is ensured as much as possible, but what makes Jiang Liu'er very puzzled is that it should be very difficult to recover the powerful kinetic energy shot with a strong bow and crossbow of the Great Qin, if the designer can ensure the coordination of the two aspects well and not mess up, then he must be a genius!

At the very least, he has a very high attainment in mechanical arts.

Jiang Liu'er couldn't help but sigh in admiration.
