In the brightly lit underground karst cave, more than 100 soldiers were on alert, and the sudden sound of large-caliber firearms echoing throughout the cave from time to time.

A spatial rift with a height of more than three meters was quietly suspended in the air more than one meter above the ground.

In the vicinity of the spatial rift, more than a dozen dwarf humanoids the size of a meter, with dark rust or dark black scaly skin, fell in a pool of blood.

If Gu Cheng were here, he would find that these ragged humanoid monsters that looked like lizards were none other than the lowest level monsters in the Otherworld, kobolds.

In the rift of time and space, one or two kobolds still popped up from time to time, and after these kobolds appeared from the crack, they were caught for the first time, and what they couldn't catch was turned into a corpse under the attack of heavy machine guns.

In the iron cage next to it, there were four or five kobolds.

These short, timid reptilian humanoids, with bloodthirsty and brutal tendencies in their flashing red eyes, were crowded into the corner of the iron cage at this time, and the long tails behind them swept uneasily, looking at the figures around them in horror.

The kobold, who was not much more courageous than a goblin, was already at a loss for fear when he saw the nearly 100 people next to him.

When he was in the other world, he was basically a kobold who dared to attack several times more than the enemy, but now he was forced to rush to this side by the opposite side of the spatial rift, and when he saw a large number of enemies, his first reaction was to prepare to run away.

But how could the soldiers, who had already been prepared, let this group of visitors from another world go so quickly? Of course, they had to entertain them well.

At this time, at the door of the spatial crack, several fireballs flew out and landed in a densely populated place for a group of soldiers, and several soldiers who couldn't dodge bore the brunt, and creatures began to come out of the crack, and the soldiers suffered casualties for the first time......

In the distance, with the blessing of the two passive attributes of silent walking and disappearing on the feather of the dark night of the cloak, Gu Cheng quietly hid all the way from the foot of the hillside, silently walking with disappearing, plus Gu Cheng's teleportation spell from time to time.

Without alarming anyone, Gu Cheng had successfully dived into the underground cave.

As soon as he dive into the underground cave, when Gu Cheng saw the huge spatial crack, Gu Cheng was also shocked in his heart, is the space crack here already so big? Now it seems that this is clearly a super-large space crack!

Under the attack of several fireballs, several military casualties have already been inflicted.

Then, in front of the exit of the huge spatial crack, a figure with a staff in his hand, dressed in a greasy robe of no color, was a lot taller than an ordinary kobold, but this was a kobold warlock.

Several more fireballs condensed and flew out from the staff in the kobold warlock's hand.

They had already experienced a kobold warlock's fireball attack, and when they saw the fireball rise, the soldiers had already scattered in all directions.

Except for the people near the fireball landing point to dodge, the rest of the centaurs continued to attack the kobold warlock.

With the arrival of many firearm attacks, after suffering the damage of a few bullets, the kobold warlock quickly opened his shield, and a transparent invisible air stand round shield suddenly appeared on the kobold warlock's body, and then many bullets hit it, like a stone sinking into the sea, only a few ripples, and there was no movement.

Immediately after, a mouthful of fiery dragon breath erupted from the mouth of the kobold warlock, and the dragon's breath swept left and right, and the kobold corpses near the spatial rift and the soldiers who were closer to them were instantly reduced to ashes in the blazing dragon breath.

Gu Cheng, who was hidden in the shadows, looked at the scene in front of him, even the 5-ring spell Dragon Breath Technique had already been used, the magic of the 1 to 3 rings belonged to low-level professionals, the spells of 4 to 7 rings belonged to medium-level professionals, and the 8 and 9 rings corresponded to high-level mages, so the kobold warlock in front of him was already a mid-level professional.

Unexpectedly, this super-large spatial crack was already able to allow the life of an intermediate professional of this energy level to enter and exit.

Seeing that the life not far away was enough to allow the life that had reached the intermediate professional energy level to enter and exit, Gu Cheng couldn't help but feel a little more excited in his heart.

Converting the level of the Dark World into the various levels of the Otherworld, then the Dark World Level 1 is equivalent to the apprentice level of the Otherworld, the Dark World Levels 2 to 10 are equivalent to the beginner Professionals of the Otherworld, the Dark World Levels 11 to 20 correspond to the Intermediate Professionals, the Dark World Levels 20 to 29 correspond to the Advanced Professionals, and the Dark World 30 to the highest level 99 correspond to the Legend to the Legend Peak.

In other words, since this spatial rift can allow the kobold warlock who has reached the intermediate level to successfully come to the Earth Star, then it can also allow Gu Cheng, who is currently level 12 and is also a mid-level professional, to go to the other world through the spatial rift.

And if the dragon vein warlock from S City before rebirth didn't lie, then the other world opposite this spatial rift is a place with a dragon heritage.

The dragon inheritance that the dragon vein warlock said in the previous life, Gu Cheng is determined to get it!

Going back to the kobold warlock, the open shield did block some bullets, but there was also a limit to how well the shield could resist.

Under the rapid and continuous attack of bullets, the kobold warlock's shield was quickly broken, and then, without waiting for the kobold warlock to replenish the shield, two large sniper bullets flew from a distance.

Two sniper bullets at more than several times the speed of sound arrived one after the other, one in the chest and the other in the skull, and the kobold warlock was cut in two in the blood mist.

With the kobold warlock killed, no monsters appeared on the other side of the spatial rift, and everyone present was relieved, and then thinking of the many comrades in the field who could no longer even find the corpses, this short-lived victory seemed to be full of bitterness.

"Dr. Li, this place is no longer suitable as a research place at the moment, you have seen the creatures that appeared in the rift just now, we must immediately call for help from our superiors, and we must send additional personnel here to prevent the monsters from escaping. ”

"I know it's dangerous here, but we ......"

Before Dr. Li finished speaking, with a "pop", many lights in the cave were instantly extinguished, and the underground cave, which was originally as bright as day, became dark again.

"What's going on?" shouted the person in charge of the field.

"Report sir, it's the cable in the tunnel that has been cut!"

"Damn, the one with the incendiary stick, throw a few into the four corners for me first, and hurry up to repair the cable!"

"Yes!"

It's just that what everyone didn't notice was that when the cable had just been cut and the cave was pitch black, a figure wearing a cloak came to the side of the spatial crack, and then walked into the spatial crack without anyone noticing.
