I have to say that although the monsters in the mysterious shelter are a lot more difficult, they also have a lot of experience, usually outside the shelter, it is almost close to a thousand monsters to make Xue Hua's experience bar move by about one percent, but here, it only takes two or three hundred monster clusters to make Xue Hua's experience bar skyrocket by one and a half percent.

And the monsters here are quite dense, basically these long corridors suspended in the void are filled with a large number of demon projections in every corner.

That's right, they're still projections, but at a much higher intensity than the monster projections from the outside.

The rules in the mysterious shelter are weird, humans don't feel any discomfort when standing on the corridor, there is air, gravity is the same as the outside world, and there are no strange rays that can harm your life and health.

But once you leave the corridor, or fly to a height of about fifty meters above the corridor, you will be like entering the deep space of the universe, not only will you be plagued by lack of oxygen and weightlessness, but also some strange hallucinations will appear in your mind.

Those hallucinations will draw you in and make you want to continue exploring the depths of this void.

However, these effects had no effect on the Zerg unit, and Xue Hua also obtained this information through the adjutant after Isha had analyzed the data obtained by the king worm from the void sampling.

The swarms are unusually resistant to all these disturbances, and the Xenosaurus and the Heavy Artillery Governor don't feel any discomfort as they roam the void, but the monsters aren't so lucky.

With the exception of the Disembodied Body's Fury, all other monster projections are incapable of moving in the Void like humans, and once they are pushed into the Void from the white floor of the hallway, they will instantly crumble and reduce to a pile of energy fragments.

These shattered energy fragments couldn't even be reused by the Leviathan, and Xue Hua couldn't get the slightest experience from them, so after trying once or twice, he began to forbid the swarm to drive the monsters off the corridor platform.

Of course, it is only forbidden to kill a large number of enemies in this way, and if it is occasionally squeezed down, it can only be said that it is unlucky.

With the support of the Heavy Artillery Governor and the Alien Dragon, the swarm's monster-killing efficiency was very high, and in just one day, Xue Hua's experience bar had risen to fifty percent of level 16.

You know, he's only been up to level 16 for a short time!

This speed of gaining experience even made Xue Hua a little reluctant to leave here for a while.

However, the mysterious shelter is very large, so big that it is difficult to find the teleportation point of the ancient tomb in a short time even if you sit on the king worm, according to ancient records, the teleportation point should be located in the center of the mysterious shelter, in a large hall that can be reached by no normal path.

This is obviously different from the game again, in the game, the terrain of the mysterious shelter is supposed to be four corridors extending from the small station in the center in four directions, and the waypoint of the tomb is at the end of one of the corridors.

But where is the "Great Hall" recorded in this ancient book, Xue Hua still has no clue, the king insects have already been scattered by him, and there are dozens of alien dragons around each king insect to escort them, in case those who can operate in the void angrily attack the king insects.

But until now, the messages sent back by the king worms were still endless corridors and bustling monsters on the corridors, and no buildings that looked like "halls" appeared in their field of vision.

"Oh my God! It's big enough to fit half of the Aranok Desert, right? ”

Xue Hua checked the exploration records sent back by Wang Worm, looked at the labyrinth-like overlapping and repetitive white corridor, and couldn't help but let out a sigh.

No one told him that it was so wide!

When is this going to be found?

He shook his head and turned his attention to the ongoing battle beneath the king worm.

The swarm is worthy of being a fighting race specially born for war, they are completely tireless, fearless, and always fierce and brutal to fight for the master, when Xue Hua rested comfortably in the belly of the king worm, the swarm led by the worm mother was still advancing rapidly towards the front with the support of the air force.

Although he didn't find the "main hall" that existed in the record, Xue Hua still chose a general direction for the insect swarm according to the density of these corridors in the king worm's investigation, and in the depths of this direction was the largest corridor platform that the king worms had found so far, and the platform was almost stuffed with monsters, and the number was estimated to be more than three thousand.

With so many monsters, he could almost give Xue Hua about ten percent of his experience at one time, and of course he would not let go of anything.

......

Just when Xue Hua was comfortably upgrading his level for himself, in another corner of the mysterious shelter, Mage Ryan was already driven crazy.

He had to desperately use the teleportation skill all the time now, because this damn ghost place was really full of monsters, and the strength of these monsters was quite abnormal, all of them were around level 30 strength intensity.

There are even some Golden Monsters and Blue Monsters who have reached level 40-50 strength strength, and if this kind of strength strength monster only comes in small groups, he is completely warmly welcomed, because it is equivalent to sending him experience and equipment.

But if there were five, six, hundred, or even thousands of them at a time, and there was no room to dodge around him, then he couldn't afford it......

And it just so happens that the monsters in this place come in whole groups and hordes......

So he can only find one direction now, and keep using the teleportation skill, but fortunately, the mage's teleportation skill can automatically help locate the safe environment, otherwise he would have passed into the pitch-black void long ago......

However, such frequent use of teleportation skills is simply unbearable in terms of his mana, and he can survive for a day entirely by relying on a large number of mana potions prepared in the inventory, as well as an eagle orb that was previously punched out and has a +5 heating skill.

But now, there are not many mana potions in his inventory, and he can't get back at all with his skill level if he relies purely on heating skills.

He's an electric method, not a fire method, in the past, he relied on sufficient supplies, and the heating skill was only a symbolic point, even if he had a staff +5 in addition to some of the best equipment on his body +2 full skills, he only had a heating skill of level 8.

The level 8 heating skill only provides 114% mana regeneration, which is a drop in the bucket based on the frequency with which he currently uses the teleportation skill.

"Damn, shit, shit!!" Ryan activated the teleportation again, and a brush appeared in the middle of a staircase, and he glanced around, only to find himself in the middle of a group of sheep-headed demons, these blood-red eyes and sharp teeth looked at him like they were looking at a delicious piece of cake!

As a last resort, Ryan had no choice but to desperately squeeze the mana in his body, and he used his teleportation skill again.

This time he had good luck and landed on a platform without monsters.

Although the shelter was full of monsters, there was occasionally an empty area, which was almost a salvation for Ryan now, and he glanced around gratefully, and then prepared to sit down and rest to relieve his nerves, which were about to be strained.

However, before his ass could hit the ground, a huge lightning bolt suddenly erupted from a strangely shaped stone pillar in the center of the platform.

Immediately afterwards, an arc as thick as a child's arm slammed into Ryan's shield, the mana shield of the electric method is based on mana, where is there still half a bit of mana in Ryan's mana pool now? So the lightning shattered his shield almost instantly, slashing at his chest.

The mage snorted violently, his face suddenly turned pale, and then spat out a large mouthful of blood.

Without saying a word, he directly took out a jar of purple potion from the inventory, and he didn't care about the distress, pulled out the lid and poured it into his mouth.

The full rejuvenation potion took effect very quickly, and Ryan was able to teleport before the pillar could shoot a second bolt of lightning at him.

He didn't dare fight this thing at all, because it was immune to lightning spells at all.

This pillar is not a monster, but a trap left behind by the Hradik mages who built it before, and its name is the "Lightning Spiral", which is a terrifying self-defensive spell trap that can shoot lightning like enemies within its sensing range and can also release "novas" when under siege.

It's immune to toxins and lightning spells, and it doesn't provide any infernal energy or item drops, so this trap-type opponent is a big annoyance to anyone.

Especially the electric mage, if you run into it alone, you can't fight at all.
