Chapter 119: Invisible Boundary

The Zerg army continued to fight with the nearby ghouls. The battle of tens of thousands of troops here seemed to not attract the attention of the ghouls at all.

The ghouls not far away were still busy in an orderly manner, not affected by the battle here at all.

"Does this look down on my Zerg?"

Wu Qing was a little confused. He always thought that the appearance of ghouls was suspected of targeting the Zerg.

Moreover, their racial organization model and known arms are somewhat similar to those of the Zerg, which is too coincidental.

But the situation of the ghouls seen now and their reactions at this time seem to be wrong.

With the strength of the ghouls, if they want to target the Zerg, their attack strength will not be so small, nor will they be indifferent to the battle here.

Wu Qing can feel that there are many extremely threatening beings in the central area of ​​the ghouls. With the strength of those beings, they should have discovered the battle here.

Since the ghouls are so calm, Wu Qing will not be polite. The Zerg army will first eliminate the nearby ghouls.

As long as there is enough benefit, even if all the Zerg troops that rushed out are lost here, it is not a pity!

Because this will bring greater gains to the Zerg. With war, the Zerg will develop and progress!

The nearby ghouls were driven out of the passage by the Zerg army. Those passages look interconnected, numerous and complex, but they are actually connected together.

Once the Zerg army passed, all the ghouls were attracted here. Now that the Zerg army has killed them, the ghouls stationed in the passages and the survivors have been driven here.

At this time, there are still 30,000 to 40,000 ghouls, all of which are ordinary ghouls. Those giant ghouls seem to be slow in movement. Those that encounter the Zerg army are all destroyed by the hydralisks.

Nearly 10,000 hydralisks of the Zerg have all left the passage. The nearby area is like an enclave of the underground world, a large platform that is higher than the underground world.

The area of ​​the large platform is very large, and hundreds of thousands of troops can be deployed here for a war. Such a battlefield is very suitable for the efficient killing of the Zerg. It didn't take much time for all the ghouls who fought to the death to be wiped out.

Wu Qing has been observing the ghouls under the platform, and finally he found something wrong. The ghouls below seemed to be unable to feel the war on the platform, rather than being indifferent to the slaughter of their own kind.

Wu Qing asked the host to rise to a higher position and observe the edge of the underground world. It was found that there were indeed no ghouls in the area near the cliffs at the edge of the underground world.

A Zerg puppy jumped off the platform and entered the area below the platform. The busy ghouls nearby immediately discovered the Zerg puppy, swarmed up, and surrounded and killed the Zerg puppy.

A Zerg host flew out of the platform area from the air. With the host's powerful mental power and perception ability, it did not notice anything unusual, because the host's own talents were fully activated, and the ghouls below did not discover its existence.

The host flew forward for a short distance, then flew back, and smoothly flew back to the huge platform where Wu Qing and the Zerg army were.

The host stretched out its tentacles, rolled up a Zerg puppy, and slowly flew back along the path just now. When they crossed an invisible boundary, the ghouls below immediately found them.

The host quickly retreated and exited the boundary. The ghouls below seemed to have suddenly lost their target. They searched everywhere, but could not find the host and the Zerg puppy that they caught.

It seemed that there was an invisible barrier that isolated the underground world from the world where Wu Qing was, but this isolation seemed to be only effective for the creatures in the underground world. The creatures outside the underground world could enter and exit freely.

"There is no trace of human intervention. This is another rule-level restriction. This world is really too chaotic!"

Wu Qing had studied the system's formation and the Yuanqi formation of the original world, but he could not understand what this invisible barrier was at all, and he could not even detect it.

The formations of the system are all applications involving the essence of the formations. No matter how magical the formations in this world are, some traces should be found, but here, Wu Qing found nothing.

The powerful spiritual power of the Zerg collective consciousness queen descended on a one-star host. Based on the Zerg's science and technology and Wu Qing's understanding of the formations, nothing was found.

So Wu Qing said that this is a world rule-level restriction. What is stipulated by the world rules is the truth in this world. It stipulates that the creatures in the underground world cannot come out. The creatures in the underground world cannot come out. There is no reason to explain.

"Ghouls have appeared outside the underground world. This restriction should be a complex restriction. Under certain conditions, creatures from the underground world can also appear in the outside world."

"Ghouls attacking the Zerg territory are targeting the Zerg. These ghouls can appear outside the underground world, which should be related to those weird things."

"We will definitely find something here at night, but we can't stay here at night, so we can only give up."

"However, we can be sure that creatures from the underground world cannot easily come out, and the Zerg territory can develop with peace of mind for the time being."

"Whether some guesses are correct depends on the performance of the weird things and ghouls tonight, and what tricks they can play."

"..."

Wu Qing figured out some things instantly, but there are still more mysteries that cannot be solved for the time being.

The creatures in the underground world are too strong, so Wu Qing will not let the Zerg enter the underground world for the time being. This magical underground world can only be left until the Zerg is strong enough to explore and attack.

For the Zerg, this underground world is an endless storage of resources.

…

Wu Qing asked the Queen to control the host to continue to observe this underground world and collect as much information as possible about the underground world.

The Zerg army no longer needs to stay on this platform. Most of the Zerg troops began to retreat. The Zerg dogs responsible for reconnaissance explored all the passages and reported them to the Queen for record.

Nearly 100,000 Zerg troops withdrew one after another. Wu Qing left most of the troops in the newly built cave base and drilled under the Zerg fungus carpet that was about to cover the entire cave space to recover in hiding.

The newly built Zerg cave base has already built many Zerg defense buildings densely, just like the Zerg underground base.

Having learned from the lessons of last night, the Zerg's first main line of defense has been moved back a bit to the middle, leaving enough buffer space to deal with the various tactics that the Ghouls are constantly creating.
