In a day and a half, Xiao Chen mastered the use of the ballista, he could complete the winding in two seconds, load the ballista in one second, and aim and fire in another second. Baidu search purple pavilion .

Firing a crossbow in four seconds and being guaranteed to shoot where it is going is a very fast speed.

There are a total of 360 crossbow guns, and in addition to the 10 used for practice, there are still 350 of them, which should be enough to deal with the Hydra.

As for boomerangs, he practiced them too, but he always found it difficult to do so. It's easy to throw it out, it doesn't take much effort, and it can fly in the sky for a long time, but it's too difficult to hit the set target.

Anyway, so far, he hasn't succeeded once.

Forget it, it's enough to have a big killer like a ballista, and you don't have to waste time on other things.

After three days of recuperation, the two wounds were healed, the damaged meridians were also dredged, and he became vigorous, and after a little preparation, he set off for the Hydra's lair.

At a distance of five hundred meters, he chose a flat area and carefully placed the ballista.

After the installation, head to the hill next to the cave, hit a dowel, hang a few buckets of oil, and quickly leave.

Two hundred meters away, he was sitting on the back of Da Hei, and a hundred meters away, the fire attribute leaves were floating in the air.

Sou......

It shot a flying needle, and at the same time, the little marquis slammed his legs between the horse's belly, and the big black raised his four hooves and ran towards the ballista.

The flying needle cut through the field control and accurately shot into the wooden barrel that surrounded the middle, and the wooden barrel burst in response, shattering all the surrounding wooden barrels, and the flames rose.

The fire filled with oil and wood chips began to fall, and all but a few fell on the outer edge of the hole, and the rest of the metal fell into the hole.

Three hundred meters away, it only took ten seconds for Da Hei, and before it could stand firm, Xiao Hou Ye couldn't wait to jump off the horse, and quickly controlled the ballista, and the crossbow gun that had already been hung was aimed at the direction of the hole.

Soon, the roar of a hydra was heard from the entrance of the cave.

The nine snake heads extinguished the hissing sound together, and it extinguished the flames as fast as it could, climbing up the cave wall, and it was not difficult to tell from the eighteen angry eyes that it was really angry.

Half a minute later, it leapt from the hole.

Xiao Hou Ye had already calculated the amount in advance, lowered the ballista slightly, and then pulled the crossbow machine.

Sou......

The four-meter-long crossbow spear drew a perfect parabola in the air, and in the middle of the falling hydra, the not-sharp head of the spear actually pierced the fine scale armor of its abdomen.

Rumble......

The explosion sounded, and the little marquis had no time to observe what kind of effect the explosion had on the hydra, so he turned the winch as fast as he could, and skillfully wound the ballista.

As he prepared for the second launch, the Hydra fell to the ground, and the flames of the explosion dissipated.

Simple aiming, pull the crossbow again, flatten the ballista, turn the winch, wind up the gun......

Rumble......

The Hydra was hit again, this time in the abdomen, with a crack-like wound in the fine scale armor, and black-red viscous plasma deep in.

One of the heads spotted the direction of the ballista, and it immediately swung its wounded abdomen and rushed in that direction.

Don't look at this guy is injured, but his travel speed has not been affected in any way, and the nine heads shake up and down with the movement of his body, looking like he is menacing.

Sou......

The third crossbow shot out, and the hydra subconsciously dodged, but it didn't expect the crossbow gun to be faster, and before it could make other movements, it was shot in the third neck on the left.

Rumble......

The explosion caused this neck to flung backwards uncontrollably, and the two hands next to it were blown up against the other necks, stained with blood.

The neck that was hit was the most severe, with several scales lifted to reveal a pink internal structure, and the snake's head on it was even more bloody at the corners of its mouth.

The metallic head shoots out a long cone, but because it is too far away, it flies a short distance and becomes the end of a strong crossbow, landing on the ground.

Rumble......

Xiao Chen shot the fourth crossbow spear, and the hydra was still four hundred meters away, but by the time he installed the fifth, there were only more than a hundred meters left.

The Hydra was blown up with seven meat and eight vegetables, and after tens of thousands of years of peaceful life, it has long been unable to remember the taste of ballistas, which can be regarded as revisiting.

He hurriedly shot the fifth crossbow spear, no matter what the result was, first put the big killer into the bracelet, once the nine-headed body rushed over, it would definitely be destroyed first.

Due to panic, when he retracted the ballista, he inadvertently summoned a boomerang.

"What are you doing here?" He didn't have time to put it back in, because Hydra was so close.

With a thought in his mind, this time it was three hundred undead knights who were summoned, and while they were not yet fully "awake", the little marquis ordered Da Hei to speed up and escape.

The undead knights pulled out their weapons one after another, they were originally going to chase Xiao Chen, but they were just in time for the hydra to pounce.

Puff ...... Boom......

The Hydra knocked over a dozen undead knights at once, and the others waved their weapons at it.

Jingling...... Syllable......

The undead knight with the combat power of the Immortal Martial Realm was helpless against the Hydra, unless the blade hit its injured part, it was useless.

The nine snake heads attacked at the same time, and for a while, metal cones, flames, stone bullets, steel needle grass, and ice picks appeared one after another, and more undead knights were bitten by them and swallowed directly.

The little marquis glanced back in the process of escaping, and the three hundred undead knights only lasted for more than ten seconds before they were all wiped out.

The hydra continued to chase, and although the speed of the big black was fast, it was still a small amount compared to it.

Keep releasing the Undead Knight?

They are not opponents at all, and they can only symbolically delay time...... He suddenly noticed that the boomerang was still in his hand, and threw it back without thinking.

In fact, he just felt that it was better to be empty-handed than to be occupied, and he didn't think about what effect it could play.

Woo......

Since the boomerang is a hollow structure, it makes a sound similar to that of a child crying when flying.

Xiao Chen didn't take it seriously, and Hydra didn't take it seriously, in its eyes, the boomerang was no different from a fallen leaf floating in the air.

The boomerang had already flown behind the Hydra, but it turned back in a strange way, and after the turnaround, it spun even faster.

Woo...... Sou......

Burst......

The boomerang hit the first head of the Hydra from the left, and the sharp inner eaves actually pierced through the fine scale armor, and the golden head let out a mournful sound.

And that's not all, the boomerang takes this neck as the center of the circle, and quickly spins up, cutting deeper and deeper until it hits the vertebrae, making a strange sound that makes people's hearts tremble.

The little marquis inadvertently turned his head and saw a snake head rising to the sky, with a piece of gold in the center of his eyebrows!

And the boomerang that had made a miraculous feat broke away smoothly, and flew towards him with a whirl, the speed became slower and slower, and he subconsciously stretched out his right hand and caught it steadily.

A little boomerang can actually cut off a snake head, and the little marquis looks down at it, which is simply incredible!

The hydra's eight heads let out a mournful roar together, leaving behind the golden head that had fallen to the ground, and turned and fled towards the lair.
