The importance of this knife is self-evident!

Xu Xin immediately summoned the treasure chest monster, threw the knife into its mouth, and then put it away.

Judging from the previous incident with Xiaohong and the pterosaur statue, doing this will prevent them from noticing the location of this item!

Sure enough, after he did this, the giant not far away paused for a moment, and then his steps became hesitant.

Now, it is indeed impossible to determine the location of the knife!

Will it come again?

Xu Xin narrowed his eyes.

He wasn't going to ask the rest of the Explorers to help.

There is no point in telling them about the behemoth's problem.

You can only rely on yourself!

With their tree house heavy crossbows!

At this time, Li Wenxi ran up from below.

"I just saw Qin Fu come back. Was he the one who brought this big monster back?" Li Wenxi asked in surprise.

"Well, but he also brought back a good thing."

"nice one?"

"Now is not the time to talk about this. I'll tell you after we solve this problem!"

Xu Xin looked out the window and saw Tong Kong shrink.

Because the green-skinned blood-marked troll holding a mace has started running towards this side!

Soon, the distance was only four or five hundred meters!

"Oh oh!" Coco was also frightened. She jumped onto the back of the Silver King, who was in a guard posture and baring his teeth, and buried her little head in the fur on the Silver King's neck.

As if I can't see it, I won't be afraid.

Xu Xin ignored Keke and the others and contacted Lou Feier directly: "Fire the super heavy crossbow!"

"receive!"

The moment Lou Feier finished speaking, her tree house and Jin Yue's tree house suddenly made a very clear mechanical sound that could be heard from nearly a hundred meters away!

Then, several heavy crossbow bolts cut through the sky and shot towards the troll four hundred meters away!

The speed is amazing!

But the trolls reacted quickly too!

Its body was huge and heavy, so it was relatively clumsy, and it was almost impossible for it to dodge. But it actually roared and swung the spiked mace in its hand!

In this wave of attack, three heavy crossbow bolts were fired from Lou Feier and Jin Yue's tree houses respectively, for a total of six heavy crossbow bolts. Four of them were directly knocked away by this swing!

As for the remaining two bullets, one hit its chest and the other shot into its abdomen!

Then, a roar was heard!

“Boom boom boom!”

Several deafening explosions were heard, accompanied by the troll's somewhat painful and even more angry roar!

Blood and flesh flying everywhere!

There were two very conspicuous wounds on its chest and abdomen!

"pretty!"

“So strong!”

“Bullshit!”

There were cheers from downstairs.

After being comforted by Li Wenxi, the people downstairs were no longer afraid, but regarded the invasion of the giants as an exciting battle.

"So powerful! The troll is injured!" Li Wenxi also cheered.

Xu Xin is not as optimistic as them.

He frowned.

This low-level delayed explosive heavy crossbow did not actually penetrate the blood-veined troll's body, but only penetrated its epidermis!

The wounds of the trolls seemed serious, but that was because they were too small compared to other trolls, so looking at such large wounds seemed exaggerated, but in fact, the injuries suffered by the blood-marked trolls were only superficial injuries!

At this moment, the injured blood-marked troll suddenly let out a long roar towards the sky!

A long roar that shook the mountains and forests!

Everyone nearby had a buzzing head and covered their ears.

The crown of the tree house shook violently, and countless banyan leaves fell down due to its roar!

At the same time, blood patterns on its body suddenly lit up!

The dense blood veins began to emit a strange red light!

Immediately afterwards, the two wounds it had just received began to visibly wriggle and heal!

It can actually heal itself!

"Continue attacking!" Xu Xin said immediately.

“Kaka!”

Lou Feier and Jin Yue’s tree house immediately fired the second batch of heavy crossbows!

This time, the troll's movements were a bit more agile than before! It swung its mace again, directly smashing six heavy crossbows away!

But this time, Lou Feier and the others launched eight missiles!

Four super-heavy crossbows were installed on each of their tree houses, and they were all facing the opposite direction of the main tree house, which was the direction of the trolls now!

Two heavy crossbows pierced the troll's skin again. The troll wanted to reach out and grab them, but it was too late.

“Boom boom boom!”

Along with the troll's painful cry, two blood flowers burst out from its body again!

At the same time, Xu Xin also operated the control panel, controlling four super-heavy crossbows to fire!

He did not use that powerful weapon because he only had one round of ammunition and was afraid of being hit by the opponent's mace.

That powerful weapon must be used at the critical moment!

The crossbow flew through the air, and the troll swung the mace again in pain, but still a heavy crossbow shot hit it!

"boom!"

Blood and flesh splattered!

Immediately afterwards, continuous sounds of machinery came from the east!

At Ma Hongwei's tree house, dozens of heavy crossbows were thrown out directly!

These heavy crossbows drew beautiful parabolas in the sky, aiming directly at the blood-veined trolls!

“BOOM ...!”

Thick smoke billowed, engulfing the troll!

"Did this... succeed?" Li Wenxi said softly, his throat rolling.

"...Don't say that, otherwise..."

"roar!

"A deafening roar was heard, and a mace was swung out from the thick smoke. Then, a giant rushed out from the smoke!

There were wounds all over its body, and it was covered in blood. Its bulging eyes were bloodshot, and it looked miserable and ferocious!

The blood patterns on its body became brighter!

The wounds on his body were healing rapidly!

It also knew that it was at an absolute disadvantage at this distance, so it rushed directly towards them!

Very fast!

Three hundred meters, two hundred and fifty meters!

"Keep firing!" Xu Xin gave the order directly, "Hold him back, I'll find an opportunity to unleash my weapon!"

“Kakaka!”

The sounds of mechanisms continued to ring out around it, and dozens of delayed-type explosive crossbows rushed towards the troll again, forcing it to stop temporarily to resist.

At this time, Xu Xin activated his mind-reading ability.

At this distance, I can already read your mind!

"The secret key...disappeared right here! Destroy this place and retrieve the secret key!"

Secret key?

It’s that bronze dagger!
