The undead are a very special kind of creature, this kind of creature does not exist in the form of life like humans, they are very small, they can be attached to any living being, and they can also be attached to some dead things.

And the undead evil things that Xu Tianhai and the others see now, they are attached to the bones.

The reason why undead evil creatures have the word "immortal" is because if they can't find food, they will go into a deep sleep.

Once they go into a slumber state, they can have a long lifespan.

In many tomb robbery stories, those tomb robbers are most afraid of this kind of immortal evil.

Of course, this kind of immortal evil thing is not really completely immortal, what they fear most is the power of the fire element.

Soon, a group of warriors behind Lin Xiyu had already prepared the rocket.

As soon as she gave the order, those warriors shot rockets one after another.

Woohoo!

The rockets made a rapid sound of breaking through the air, and they all quickly shot into the bodies of the undead.

There was a loud bang, and soon, the fire array contained in those rockets opened.

The rockets exploded, bursting with incredible power of fire.

The undead were all reduced to ashes by the power of the flames.

Seeing that the other immortal evil creatures had been wiped out, many warriors cheered.

"Guys, we're running out of time!

Lin Xiyu didn't want to continue to delay time here, she just wanted to advance as soon as possible.

Those cannon fodder were immediately driven to the forefront by Lin Xiyu's men, and those cannon fodder immediately cursed Lin Xiyu and the others in their hearts.

Xu Tianhai exhaled a breath of turbidity, he just took advantage of everyone's attention to those immortal evil things, he secretly took out the Huangquan Sky Lantern.

"I hope this Huangquan sky lantern can still play an effect!"

He activated the Yuan Force, and soon, he triggered the magic circle inside the Huangquan Sky Lantern.

The Yellow Spring Sky Lantern will quickly release a wave of energy, which can make any monster within tens of kilometers of the vicinity sense its presence.

When the monsters sensed its presence, they would quickly rush towards it.

This is the terrible thing about the Huangquan Sky Lantern.

The reason why Xu Tianhai wanted to release the Huangquan Sky Lantern was because he didn't want more cannon fodder to die miserably here.

Moreover, he also wanted to take this opportunity to know if the Huangquan sky lantern could be used.

When the Huangquan Sky Lantern suddenly erupted into a powerful energy fluctuation, the nearby martial artists all sensed the existence of the energy fluctuation.

Their faces changed dramatically, and they hurriedly looked around, trying to find the source of the energy fluctuations.

But at this time, Xu Tianhai had already collected it into the holy weapon on the other side, and most of the martial artists could not find the source of that energy fluctuation.

Xu Tianhai exhaled, he was very much looking forward to the Huangquan Sky Lantern really being able to play a role.

After a while, the crowd saw countless skeletons standing.

Their eyes widened, and after a moment of closer inspection, they were sure that there were at least a thousand undead creatures standing up now.

"Oh my God!

The cannon fodder saw so many undead evil creatures appear in front of them, and they quickly retreated backwards.

The thousands of undead evil creatures let out a deafening roar, and after that, they rushed towards Xu Tianhai's team like a tide.

Lin Xiyu didn't stop the retreat of those cannon fodder, she still needed those cannon fodder to find a way for her.

Now that a large number of undead evil things have appeared in front of her, she naturally wants to kill those undead evil things in front of her first.

"Everybody prepare the rocket!One, two, three, shoot!"

Lin Xiyu immediately ordered.

Woohoo!

Countless rockets shot at the undead again, and after they hit the bodies of the undead evil creatures, they exploded one after another.

The thousands of immortal evil creatures were quickly wiped out by Lin Xiyu's men.

Lin Xiyu exhaled a breath of turbidity, her eyes flickered, she felt that the situation just now was too strange.

Her spiritual power was still very strong, and she had sensed that powerful energy fluctuations were coming from the direction where Xu Tianhai was.

Moreover, she also sensed that there was a faint spatial fluctuation coming from Xu Tianhai's location just now.

She felt that Xu Tianhai had a big problem.

Her eyes flickered, and after a while, she called two of her men.

She secretly transmitted the voice, asking those two subordinates to keep an eye on Xu Tianhai's actions for her at any time.

How dare those two subordinates go against her will, they follow her request and secretly keep an eye on Xu Tianhai.

Once her men had eliminated the skeletons, she let the cannon fodder move on.

Although those cannon fodder were very unhappy, but now, they had no choice but to follow her orders.

At this time, they only had hatred for Lin Xiyu in their hearts, and they did not have any gratitude.

They knew that if it wasn't for the undead evil creatures who suddenly all stood up, but when they entered it, they all stood up again, then they didn't know how many people they would lose as cannon fodder.

"Fortunately, those undead evil creatures don't have brains, they won't ambush, otherwise, we would have died here today!"

Those cannon fodder dare not speak out against Lin Xiyu, they can only put hatred in their hearts.

Seeing the results of his test just now, Xu Tianhai exhaled a breath of turbidity.

"It seems that this Huangquan Sky Lantern can really wake up all the nearby monsters and attract them over!"

The team continued for several kilometers, but luckily, they didn't encounter any undead along the way.

"Look, there's a deep pit ahead!"

A cannon fodder shouted loudly.

Xu Tianhai saw a circular clearing appear in front of him, and there were no white bones in the circular clearing, but around the round clearing, there were piles of white bones.

And in the very center of that circular clearing, there was a huge hole.

"There's definitely something wrong here!"

The cannon fodder didn't move on, they thought there might be some treasure in the pit of the circular clearing.

Lin Xiyu checked the surroundings of the circular clearing, and she found that there was a small stone wall that had been manually excavated around the surrounding of the circular clearing, and she found that this small stone wall was half a meter higher than the ground.

Moreover, she found that there were countless formations on the outer walls of the small stone wall.

"This stone wall may be used to block those monsters from coming up, judging from the fact that there are no white bones in this clearing, I judge that those monsters should not come up, and inside this cave, it is very likely to be used to protect the arrangers!"

Lin Xiyu analyzed.

As soon as the other martial artists heard it, they felt that what Lin Xiyu said was very reasonable.

"Shall we go down and have a look?"

A warrior asked.

"Of course we have to go down and find out, otherwise, we have worked so hard to get here, just to kill some undead evil creatures?"

Lin Xiyu replied angrily.
