However, considering the reason why the mutant beasts were scattered and difficult to hunt, Du Yun was not in a hurry to leave.

Although he is not afraid of consuming a lot of Yuan Stones, if he uses the Eight Bull Crossbow to hunt a demon beast with the strength of the day after tomorrow, it really feels like "cannon fighting mosquitoes" is overkill.

It's too extravagant!

What the hell is going to do to lure the mutant beasts together? Du Yun thought secretly in his heart.

That's right, that thing!

As if thinking of something, his eyes suddenly lit up, and with a wave of his hand, he took out something from the warehouse again that he hadn't used since he got it—the core of the mutated weeping willow of life.

As soon as the core of the tree of life was taken out, vigorous vitality emanated from it.

Mo said that Du Yun himself felt comfortable after feeling this vitality, and the mutated goshawk who was lying on the ground obediently not far away raised his head in vain, and looked straight at it with a pair of eyes.

In its eyes, there is a strong color of longing.

"Hehe, that's you!"

Du Yun ignored the pleading in the eyes of the mutant goshawk, and after muttering with a smile, he directly jumped on the mutant goshawk's body again with the core of the tree of life.

The Eight Ox Crossbow has been loaded with Yuanshi and can be attacked at any time.

"Gather your breath, fly low, and take a spin around here first!"

"Wow!"

Although he didn't get the mutant core, he was still very excited to smell the breath of life emanating from his back.

After hearing the master's command, it suddenly let out an eagle cry, flapped its wings and flew up from the ground, and at the same time completely restrained its breath.

Even if an innate level demon beast appears, it can't see the strength of the mutant goshawk, and will only treat it as an ordinary demon beast.

……

The trial area was very large, and when Du Yun flew into the air with the mutant goshawk, he looked around, and there was no end in sight except for the vast green mountains.

However, he knew that he was still in the outer area at the moment, and if he wanted to find that innate level demon beast when the time came, he only needed to keep flying inside.

Now, let's clean up all the mutant beasts in the outer areas!

Thinking of this, Du Yun commanded the mutant goshawk to fly towards the forest where he came, while he held the Eight Ox Crossbow in one hand and the core of the Life Tree of the mutated weeping willow in the other.

The surging vitality emanated from the inside, and soon drifted out with the wind.

Oh!

Oh!

……

The height of tens of meters does not affect the effect of the core of the tree of life, and when the mutant goshawk flew around the forest over the top of the tree, a burst of excited beast roars suddenly came out of the forest.

Through the gaps in the sky above the trees, you can faintly see the figures that continue to gather inside.

The rich breath of life that permeated the air almost drove them crazy!

When Du Yun saw this scene, he immediately made the mutant goshawk slow down, trying his best to keep these mutant beasts from losing.

Finally, when he and the mutant goshawk returned to the open area outside the mouth of the valley before, with the vibration sound of "knock", "knock", "knock", countless mutant beasts suddenly rushed out of the woods.

Colorful tigers, sturdy cheetahs, fanged wild boars and hordes of gray wolves......

As soon as they came out, they didn't pay attention to the other mutant beasts around them, and directly raised their heads and looked at the mutant goshawk flying in mid-air with bloodthirsty and greedy eyes.

At a glance, there are hundreds of these demon beasts, and most of their strength is between the first and second levels of the day after tomorrow, and there are not many of the three layers of the day after tomorrow.

Moreover, there were more demon beasts in the woods and other places that were alarmed, and they began to rush towards this side.

Du Yun stood on the mutant goshawk and glanced down, then looked around the sky, and found that there was no flying mutant beast.

"That's great!"

Therefore, he directly urged Yuan Li to activate the Eight Bull Crossbow, and a three-meter-long crossbow arrow was instantly generated into a load, stretching the crossbow string into a semi-arc.

Wait until it's all ready.

Du Yun took advantage of the opportunity of the mutant beasts below still gathering together, and immediately connected his vision with the mutant goshawk, controlling the other party to swoop down like a fighter plane.

Oh! Oh! ……

The mutant beast group below was completely stimulated by the rich breath of life, and when they saw the goshawk swooping down, they immediately roared excitedly.

Some even jumped up directly, waved their claws and pounced on the goshawk.

"The grasshopper shakes the tree, it's ridiculous!"

Du Yun, who was swooping down, looked at this scene, and just sneered, not only did not dodge, but instead made the mutant goshawk speed up its dive speed again.

Poof!

Sharp as a blade and as strong as steel, the wings slashed through, instantly cutting the two acquired double mutant beasts that pounced on them in half.

At this time, Du Yun's eyes flashed fiercely, and he launched an attack without hesitation.

Bang!

With the sound of the bowstring collapsing, the sharp crossbow arrow instantly turned into an afterimage, tearing through the surrounding space all the way and slamming into the group of demon beasts below.

Bang! Bang! Bang!

Immediately after, Du Yun controlled the mutant goshawk to turn around suddenly, and shot out three arrows in succession.

This is just a normal attack of the Eight Bull Crossbow, but it is still not something that a group of acquired level demon beasts can withstand.

Four arrows are enough!

When the four three-meter-long crossbow arrows shot into the four corners of the mutant beast group with a dazzling brilliance, the terrifying power contained in the arrows instantly burst out, directly causing a big explosion.

Bang! Bang! ……

Oh! Oh! ……

It was as if an earthquake had occurred on the open ground, accompanied by a deafening boom, and countless clouds of smoke and dust billowed up.

Among them, there were constantly screams of mutant beasts.

At some point, Du Yun had already controlled the mutant goshawk to fly into the air, and his eyes calmly looked at the large area below that was shrouded in smoke and dust.

Cracks continued to stretch out from the smoke and dust, and some demon beasts howled to escape from them, but the power of the rippling crossbow arrows tore them to pieces in an instant.

In the air, the strong smell of blood began to permeate.

But soon, Du Yun was in no mood to pay attention to these, and a burst of system prompts suddenly sounded in his mind.

"Ding, kill a heavy mutant beast the day after tomorrow and gain ten experience points."

"Ding, kill a heavy mutant beast the day after tomorrow, and get fifteen experience points."

"Ding, kill a triple mutant beast the day after tomorrow and gain seventy experience points."

……

In just a short moment, the experience points gained by Du Yun soared directly to five hundred points, and they were still "rubbing" and rising.

It seems that if all the nearly three hundred mutant beasts here are killed, he can gain thousands of experience points.

Du Yun was very happy in his heart.

But he still had to temporarily block out the sound prompted by the system, otherwise the demon beast would not be killed, but he would have been made into a psychotic by these sounds first!
