Xiao Chen took the hydra's nest as the center of the circle and searched around in an area of ten miles. （.）

He soon found some measures to protect against the hydra, such as vertical stone walls and arm-thick blackiron fences, as well as traps covered in spikes.

Traces left by the hydra can be clearly seen on some measures, which shows that the ancient ancestors used these things more than once to block the ravaging attacks of fierce beasts.

It's just the weapon, where is the weapon?

After wandering around for a whole day, he finally found a house half-buried in the earth in an inconspicuous place, and circled around it three times, but could not find the entrance.

After the careful exploration of Ye Zi's martial spirit, it turned out that the entrance was hidden dozens of meters away, under a tall tombstone.

After making sure that there was no danger in the entrance and passage, he left the big black and walked in by himself.

The passage is dozens of meters long with traces of ancient ancestors, and the ground is not very flat, but it does not affect walking.

A few minutes later, he came to the half-buried room, which was only a few dozen square meters in size, and there were crossbows in front of the entrance.

The crossbow is a device installed at the head of the city or in some fixed positions, which can fire larger crossbow arrows than spears, with a long range and strong lethality, and is a sharp weapon for dealing with the enemy's siege equipment.

With a height of more than two meters and a diameter of more than three meters, the crossbow arm is made of an alloy of purple gold and snow silver, which is elastic and lightweight.

Moreover, there are three sets of crossbow arms, two directly in front, the one on top is half a foot less in front than the bottom, and the third group is four feet away from the first two groups, in the opposite direction to the first two groups.

All three groups of crossbow arms are hung with crossbow strings with a diameter of one centimeter, which are grayish-white and translucent, which should be taken from some kind of beast tendon, and the hardness is extremely high.

On the right side of the crossbow, a winch with a diameter of about two feet is prepared, similar in appearance to the rudder used on seagoing ships.

The body of the crossbow is a rectangular shape with a slightly narrower upper and lower length, and when struck by hand, it makes a "gurgling" sound, and hidden inside is a complex mechanical structure such as gears and bearings.

Xiao Hou Ye judged that if you want to pull a group of crossbow arms, you must have at least tens of thousands of catties of strength, and manpower will never be able to reach it, let alone pull three groups at the same time.

The function of the winch is to use mechanical energy to reduce the force of pulling the crossbow arm apart.

He tried to turn the winch, but when he tried it, it didn't move, which made him puzzled, if the winch was not for saving effort, then what was the use of it?

The energy stored in his right arm was released, but this time it was also unsuccessful, as if something was stuck.

Carefully searching for the reason, he soon found a pin made of purple gold in the hidden place under the winch, pulled out the pin, and turned the winch with a little force.

Sure enough, it only takes a few hundred catties of strength to turn the winch, and ordinary souls can do it.

With the rotation of the winch, the three groups of crossbow arms move in the opposite direction, driving a small baffle on the crossbow body, and the baffle slides from the front to the middle and rear.

Click......

With a crisp sound, the small baffle stopped, and the winch also stopped, and could not rotate for half a minute.

On the wall on one side of the crossbow, there were three rows of ballistae, each with hundreds of them, neatly arranged on a metal shelf.

He walked over and picked up one, the length of the crossbow gun was four meters, the head of the spear was one foot long and hexagonal, the front end was not very sharp, and the connection between the body and the head of the spear was slightly bulging, in the shape of a golden melon.

Place the crossbow on the body of the crossbow, and the round body of the gun is stuck exactly in the card slot.

He made his way to the back of the crossbow, which had a special antler device for the shoulder, and the index finger of his right arm was just right to hook the crossbow.

When the shoulders are lifted upward, the upper part of the crossbow is lifted with it, and you can move freely up and down, left and right.

Resisting the idea of pulling the crossbow machine, he knew very well that firing crossbow arrows in such a small space would cause the house to collapse if it was not good, so it was better to wait until it was outside.

Loosen the crossbow machine, and in the other corner of the room, there were more than a dozen strangely shaped things neatly stacked.

Yes, a dozen pieces!

These oddly shaped objects are only a centimeter thick and slightly larger than a right angle, with the outer eaves rounded only at the top and bottom, and the inner eaves with extremely sharp blades.

The blade has serrations, which are not intentionally made, but because it has hollow holes inside, each six millimeters in diameter, and each two holes are separated by one centimeter.

I have to admit that the craftsmanship of this thing is extremely high, its side length is about one meter, but it is very light in the hand, and it does not feel heavy at all.

What are they used for?

The crossbow was used against the Hydra, and he could almost have done that, since it was placed with the crossbow, it should have been used against it.

Could it be...... Boomerang?

Although the little marquis IX was a human being, he had never used the legendary boomerang, and the answer was based on his guess based on the shape of the object.

Regardless of whether it is or not, go out and test the power of the crossbow first, and with a wave of your hand, put them all into the bracelet.

A few minutes later, he set up his crossbow in an open area, and the target had been chosen, a lone stone pillar four hundred meters away.

The stone pillar is carved with a dragon and a phoenix, with a diameter of about four feet, although it can only be cut half, but the highest point is still more than ten meters, which is a good target.

After a simple aim, the little marquis pulled the crossbow machine.

The crossbow machine is not heavy, and it is not even different from an ordinary hand crossbow, and it can be fired with a light buckle, which plays a good role in maintaining the accuracy of the crossbow gun.

Click...... Whoosh...... Boom......

The powerful force pushed out the crossbow gun weighing dozens of catties, and the crossbow turned into a ray of light in the darkness, and in the blink of an eye, it shot on the stone pillar.

Bang......

With the eyes of the little marquis, you can easily see the tip of the crossbow spear piercing into the stone pillar.

The next scene that happened surprised him was that the junction between the head of the spear and the body of the spear, that is, the part with a protrusion similar to a golden gourd, suddenly burst directly.

Rumble......

The fire was blazing, and the sound was earth-shattering.

The entire stone pillar was instantly blown into pieces of rubble scattered everywhere, and when the smoke and dust cleared, only a broken base remained.

The little marquis's eyes widened and he muttered to himself: "This is too ...... It's amazing, it's a ballista that can explode! This thing can't be called a crossbow, it should be called a ballista!"

From this moment on, the crossbow took on a new name of its own - the ballista.

He took out a crossbow gun, held the head of the gun with one hand, and the body of the gun with the other, and used both hands at the same time, and after a few rotations, the head of the gun and the gourd-shaped connection separated.

Carefully poured out a little gray powder from it, these powders were small granules, in addition to gray but also white and yellow crystals, which should be the explosion caused by them.

This is definitely not gunpowder, because gunpowder does not have such a large explosive energy, and it is barely possible to make firecrackers for the New Year's holidays, but it is not good to use them to blow things up.

There is no shortage of gunpowder in the Huaxia Continent, but for soul warriors, unless a room of gunpowder explodes at the same time, it can't hurt soul warriors at all.

Such a powerful crossbow, such a bull-forked crossbow, used against the Hydra, will definitely have miraculous results. If it hits it right, it might be able to blow off one of its heads with a single shot.

He couldn't help but get excited, and he couldn't wait to find it now to take revenge.
