The hydra fled to its lair in the blink of an eye, leaving Xiao Chen with a boomerang messy in the wind. Baidu search purple pavilion .

He never imagined that a seemingly ordinary boomerang could cut off one of the heads of the Hydra, knowing that even the strongest crossbow arrow could not penetrate its scale armor.

The size of the ballista is big enough, the ballista gun shot out is four meters long, the strength is more than 10,000 jun, and the head of the gun only leaves a shallow wound on the hydra's body, and in the end, it is necessary to rely on the energy of the explosion to expand the damage range.

Also, three hundred undead knights of the rank in the Immortal Martial Realm slashed around it, but they also failed to cause obvious injuries.

How does a little boomerang do it?

From the beginning, he didn't take the boomerang too seriously, because he was not familiar with the weapon, and he couldn't do it after trying to practice it a few times, so he despised it even more.

I didn't expect it to be such an inconspicuous thing, and it made a great contribution!

The severed head of the snake fell to the ground, and after a few struggles, it stopped moving, but it still maintained a hideous expression with a bloody mouth, and its two sharp fangs flashed with cold light.

He walked over, looked at the neat incision under the snake's head, and then looked at the boomerang in his hand, and slashed at the snake's head.

Click......

The scale armor, which was originally extremely tough, was vulnerable to the tooth-shaped edge of its boomerang, and it didn't take much effort to cut a hole.

"What kind of metal is this made of, so sharp?" he looked at the boomerang, at first he thought it was an alloy of snow silver and other metals, but now it was certain that its composition had nothing to do with snow silver.

Sharp and strong, and so lightweight, he had never seen anything like it.

It seemed that it would take some more time to learn to use it, how could such a sharp weapon be discarded, and as for the snake head on the ground, he waved his hand and put it into the bracelet.

After a long day of practice, I finally found some tricks, and I was able to hit about two times out of ten.

But this result is still too bad, fighting against Hydra is a desperate thing, and the success rate of 20% is enough to knock yourself into a place of no return.

It seems that ballistas can only be used as auxiliary tools, and boomerangs can only be used as auxiliary tools.

The next day, he set up his ballista, went to the lair again, pushed down the flaming barrels, and hurried back to the ballista position.

But after waiting for a full quarter of an hour, the hydra did not appear.

He pushed more barrels of oil down, but for some reason, Hydra still didn't come up.

Xiao Hou Ye frowned, and said to himself: "Could it be that it was too seriously injured, and it hid in the nest to recuperate? Or maybe it was scared by Xiao Ye, so he didn't dare to come up." ”

Whatever the reason, the opponent does not appear, and the ballista and boomerang are not used.

He found some undead beasts as targets, continued to practice boomerangs, and finally increased the success rate to 30% for two consecutive days, but this result still did not satisfy him.

You can't become fat in one bite, and if you want to master a certain weapon in a short time, it's even more difficult than climbing to the sky.

He focused on the ballista, wondering if he could modify it to make it more lethal. After some observation, it was concluded that the techniques of the crossbow were so mature that there was no need to change them, and only the crossbow guns could be used.

The number of ballistas was limited, and it was too much of a luxury to use them for experiments, so he took out a few ordinary spears, took off the head of one of them, and tied it to one of the two to conduct the experiment. His idea was to carry six guns with one gun, so that the explosion would be six times more powerful!

The sudden weight of the gun head will inevitably shift the center of gravity forward, and the accuracy and range may be affected.

The crossbow machine was pulled, and the spear came out.

Sure enough, the range was affected, and the accuracy was barely acceptable.

When the three gun heads were tied, the firing range was extremely miserable, only less than 300 meters, and you must know that the effective range of the ballista was 1,200 meters!

Two more on the list, the result is even more miserable, only more than ten meters away, and the feather arrows shot by the children on the grassland when they practice are not even farther away.

And the front head is low, obviously aiming at the front and firing, and the ballista at the left rear landing distance is at least 20 degrees or more.

It can be seen that the ideal is plump, and the reality is skinny.

He rode on the big black and picked up the results of his efforts from a hundred meters away, in fact, this strangely shaped gun is still very fine in terms of "workmanship", first of all, the raw materials, that are six spears with the same shape and weight, in order not to deviate the center of gravity, the master accurately calculated, carefully hands, to ensure that the weight of each sub-gun head is consistent.

The method of tying is also very particular, using a very complex sailor knot to ensure that it is strong while reducing the number of ropes used, and in order to achieve balance, a counterweight is also added to the tail of the main gun, in order to reduce the center of gravity to move forward.

But all these efforts were in vain, and of course he was not reconciled.

After some thought, he decided to remove the tail weight and attach the tail wing to the bare barrel to balance the center of gravity and increase stability.

He took out a bunch of strangely shaped objects from the bracelet, and after selection, he took a fancy to a gold engraving, the thickness of which was about half a centimeter, which was just right to make the tail wing.

Soon, five tail fins as heavy as the head of the gun were ready, and they were carefully mounted on the tail of the main gun, deliberately choosing a position where the ballista would not be affected when firing.

Wiping a handful of sweat, the little marquis looked at the masterpiece in front of him, and said to himself with confidence: "There should be no problem this time, but don't let me down!"

Operating the ballista, he set the target to a stone more than 200 meters away, accurately aimed and pulled the trigger, and the action was done in one go.

Sou......

A new ballista was ejected, and from the sound of breaking the air, it was at least certainly much stronger than the last one.

It drew an arc in the air, and after flying to the highest point, the tip of the gun showed a downward trend, and the speed was very fast.

While......

The arrow of six spear heads hit the lower right corner of the stone, and he aimed at the center of the stone, which was barely acceptable.

"Ha, it's successful!" The little marquis jumped up happily, a slight deviation is nothing, the hydra has a huge body, and there is no need to point where to hit at a distance of two hundred meters!

Next, he made a more precise modification of the tail, and the third experiment hit a target 260 meters away, and the error was further reduced.

Immediately afterward, six actual crossbow guns were modified. Carefully cut five of them from under the gourd junction, and then bundle them uniformly to ensure that the main and five secondary tips are consistent.

The tail wing on the test specimen was then removed for final treatment and fixation.

After a whole hour of busy work, the new crossbow was born in his hands, and looking at his masterpiece, he suddenly felt that all the efforts he had made before were worth it.

The new ballista was placed on the ballista, and the shaft and the crossbow body grooves were tightly fitted, and there was no change in the addition of the head and tail fin.

"Great!" the little marquis shouted happily.

But a very important and thorny question has arisen, the hydra is hiding in the old nest and refuses to come out, what is the use of the new crossbow gun that the master has tried his best to prepare for it?

It seems that we have to think of a good way to lure it out.
