Chapter 2346

The prison cell where Su Xiao was located was in the middle of the first underground floor, which was used to hold stronger ground-type species.

What to do when ground-type species are starved to the point of losing their minds? The answer is to lock them up first. If they can regain their sanity by being given some food, they regain their freedom. If they cannot regain their sanity, they are sent to the 'Rebirth Ground' to make a final contribution to the tribe.

'Rebirth Ground' was just a nicer-sounding name; it was the aliens' beautiful fantasy about that place. In reality, it was a magnetic field that collected soul energy. To migrate the entire tribe, just the space-time force condensate was not enough; a super-huge central device was also needed.

The orcs would never know that this hub had to be filled by their entire race and one-third of the ground-type species.

The aliens were going crazy. If they didn't leave this world, their tribe's population would rapidly decrease due to the reduction of resources. If other races invaded this world, they wouldn't even have a chance to fight back and would eventually be exterminated.

This wasn't because the aliens had persecution mania, but because the orcs had arrived at the Ten Thousand Beasts Continent by chance from another world. Before they came, the aliens had been sleeping in this world for hundreds of years.

The infiltration was going smoothly. Because of the harassment by the assault team outside the fortress, there were many fewer aliens inside the main fortress, but it was unknown where the Mad Doctor had run off to.

Su Xiao sat in the prison cell. It was still Xiang Ignoring Bubu Wang who went to the lower level to scout the path first. After confirming there was no danger, Su Xiao and the others passed directly through the ground, layer by layer downward.

Under Xiang Ignoring Bubu Wang's cover, Su Xiao successfully entered a secret room on the second underground floor. After staying for only two minutes, he quickly arrived at the third underground floor.

He looked around and found that this was a place resembling a lair. Countless biological sacs were distributed on the third floor. This was where the ground-type species slept to reduce energy consumption.

Most of the biological sacs were already empty. Needless to say, the ground-type species inside had all gone to the surface to fight.

In the inner position of the third underground floor, many biological sacs were in a bulging state. At this moment, one ground-type species per slash meant a lot of merit points. Unfortunately, the risk of killing ground-type species here was too high. Once exposed, all previous efforts would vanish into thin air.

A few minutes later, Xiang Ignoring Bubu Wang, located on the fourth underground floor, sent news that the situation had become very troublesome. The fourth floor was very empty, with only stone pillars as cover. And here, they were guarding over ten thousand fission-type species. They were wearing armor forged by orcs and holding heavy weapons such as giant swords or war hammers.

The fourth underground floor was blocked. Now it was time to make a choice: should Su Xiao attract the attention of these fission-type species, or should the Autistic Brothers?

"Tree."

The younger Autistic Brother spoke. His older brother looked at him and shook his head.

"I will strive for 5 seconds."

The older Autistic Brother unbuttoned his jacket, which was covered in spiral nails.

"5 seconds is enough."

Su Xiao walked toward the innermost side of the third floor, passing between biological sacs each containing a ground-type species. As long as he touched one of them, he would be exposed.

After arriving at the innermost side of the third floor, Su Xiao pressed his hand on the ground. He only had 5 seconds. The 5 seconds the older Autistic Brother had won at the cost of potentially dying here—it wasn't that the older Autistic Brother was selfless, but that he wanted his younger brother to live; it was that simple.

The Autistic Brothers and Su Xiao were all responsible for attracting the guards' attention. Now it was the older Autistic Brother doing it. When they reached the fifth floor, it would be Su Xiao's turn. This was a pre-agreed plan.

When the danger level was high and there was a possibility of seizing the space-time force condensate, Su Xiao would attract the guards' attention. Along the way, the older Autistic Brother was responsible.

The Ghost Girl was the map and couldn't have any accidents. Baha needed to quickly seize 9 space-time force condensates from special aliens. Xiang Ignoring Bubu Wang was responsible for clearing the path and taking the space-time force condensates to retreat after they were obtained.

Whether Su Xiao, the Ghost Girl, and the Autistic Brothers could leave alive depended on their own abilities. Seizing the space-time force condensate was not one person's mission, but everyone's mission. At this moment, outside the fortress, other contractors on their side were risking being surrounded to harass the alien army.

After Su Xiao waited for ten seconds, a disturbance appeared on the lower level. The opportunity had come. Su Xiao disappeared on the spot. He didn't enter the fourth floor but used Dragon Flash to arrive directly at the fifth floor. If no one attracted attention, the subtle fluctuations generated during space penetration would definitely be detected by the fission-type species.

Su Xiao felt the sensation of stepping on solid ground under his feet. The fifth floor had arrived. A glass bottle fell from above; it was brought by the younger Autistic Brother, but he himself did not appear.

Boom, boom...

Smashing sounds came from above. After a while, the smashing sounds subsided.

"What's going on?"

A loud voice came from outside the room; it was the alien language.

"Human invasion."

"Invaded to here? Hmm, hearing them say it, these humans are very strong. It seems that's indeed the case."

"Two humans have already been killed."

The sound of armor clashing gradually moved away. Su Xiao leaned against the wall. A slight sound of plants sprouting came, and a branch grew out from a crack in the wall, forming a row of small characters.

'Must succeed, Bai Ye. Brother, he is gone.'

Seeing this string of small characters, Su Xiao spoke in a low voice: "Hmm, I'll do my best. If I die, there's no helping it."

After speaking, Su Xiao pushed open the iron door softly. The layout here was similar to the first floor on the surface. After exiting, it was a stone corridor that turned left and right.

Drip, drip~

In the quiet and cold stone corridor, the sound of water droplets was particularly obvious.

"The place where Nie Beini came is here, I'm sure. Her previous description matches the images in my brain; it's this floor."

The Ghost Girl's tone was firm. Upon receiving this reply, Su Xiao felt relieved. It was easy to handle as long as there was a clear goal.

It was still Xiang Ignoring Bubu Wang responsible for scouting in front. What was strange was that there weren't many guards on the fifth floor, at least not in this vicinity.

A very low grinding sound came. Su Xiao stopped and arrived in front of a doorway, looking inside.

The scene that met his eyes surprised Su Xiao somewhat. He saw several contractors being tied to metal chairs. Their mouths were blocked, their eyes were tear-stained, and their expressions were as desperate as could be.

A man wearing a hood and slaughtering clothes was sitting on a low stool in front of them, grinding a small knife with a thin edge.

Seeing this back, Su Xiao felt very familiar. This guy looked like the Mad Doctor.

In fact, this was the Mad Doctor. This guy had changed parasitic species. This time it was an alien big shot responsible for guarding prisoners in a key location. He had been ambushed by the Mad Doctor and had now become mentally disabled.

The Mad Doctor had also just arrived. Several girls from the Holy Light Paradise were trembling. They had witnessed the miserable state of their previous teammates. The Mad Doctor was very helpless; he actually hadn't done anything, but to avoid exposure, he just ground the knife to scare them.

This magical combination didn't stop Su Xiao for long. After walking for half an hour in the labyrinth-like stone corridor, the stone corridor suddenly opened up.

The stone corridor in front was more than ten meters wide and was filled with fission-type species. They were not only wearing armor but also had exceptionally strong physiques; they were all elite individuals.

Among these fission-type species elites sat a giant ape. Its whole body was covered in white fur, and it was covered in scars and suture marks. If this giant ape fought King Kong, it would be very exciting.

Sitting on the giant ape's shoulder was a woman. Her long hair was disheveled, and she carried a giant sword as wide as a palm on her back.

Both of these were parasitic species, Tier 6 big boss-level parasitic species. One was parasitic on the overlord creature, the giant ape, and the other was parasitic on a powerful human. What was more troublesome was that this seemed to be a combination.

Under these circumstances, two big bosses were already troublesome enough. If they were a combination, the degree of difficulty could be imagined. Moreover, in their vicinity, there were over a hundred small boss-level elite fission-type species, and inside the fourth floor above, there were over ten thousand sub-elite fission-type species.
