Arriving at the seventh underground floor, Lin Fei quickly discovered a problem.
From the previous situations, it is not difficult to figure out a rule, that is, the further down you go, the higher the importance of experiments. Not only is it reflected in the experimental subjects, but it is also reflected in the investment cost and research intensity.
But on the seventh floor underground, there is only one "experimental product".
human beings.
He is not a physically powerful Behemoth with ferocious and strange powers, nor an arcanist with outstanding spiritual power, nor a demon who possesses weird and evil power, nor a multi-eyed race with a variety of pupil skills.
They are ordinary human beings whose innate physiques cannot even be compared with those of orcs.
"Strange, why are the experimental subjects here all human?" Xiao Shiyu said in surprise.
"What advantages or special features do you think Human Race has compared to other powerful clans?" Lin Fei sneered, having basically guessed the reason.
Xiao Shiyu suddenly realized.
Cheap!
Human beings have a low level of life, short growth cycles and lifespans, and do not have the innate power of Arcane Core and different pupils, so they are the cheapest experimental products.
Not to mention top-end technological civilizations like God Race, even weak technological races that are still in the stage of nuclear weapons and electromagnetic weapons can mass-produce humans through cloning technology - even races that do not follow the technological system like Arcane Race can also obtain a large number of humans through breeding to refine soul stones!
The seventh floor is divided into many laboratories, and the experimental content in each room is different.
It can be seen that a small number of petri dishes have not been destroyed, and various "human beings" are soaked in cheap life nutrient solution - if they are transformed and mutated into this appearance, they can still be regarded as human beings.
Here, Lin Fei even saw many images from science fiction movies.
The body is hairless, the eyes have degenerated, the finger joints are thick and have evolved into sharp claws, the brain is directly exposed, and it has extremely long mouthparts. The skin all over the body has long been festered and fallen off, exposing the majestic blood-colored muscle tissue.
It looks very much like the crawlers in science fiction movies, or it can be called lickers.
It's just that this creature is different from the ones in science fiction movies - it has a small crystal embedded in its skull, which is connected to all the nerves in the body. Not only can it accept the instructions of God Race, but it can also provide powerful power like an energy reactor.
And a pair of huge fleshy wings grew out of its back, which obviously provided the ability to fly; behind it was an alien-like tail, which was solid overall and sharp at the end.
This is just a type of experimental product. A simple introduction to the experiment is written on the door: Experimental Product No. 996, Hunter. Low threat, low cost, high controllability, and can be mass-produced.
In addition to these, there are several different human experimental subjects.
For example, it is not an exaggeration to say that the spirit life created by destroying the human body, preserving its soul with a special magnetic field, and using heterogeneous radiation is a ghost. The ghost created in this way can strengthen itself by devouring other souls. Although the body is weak, its potential cannot be underestimated.
These ghosts all have resentment. The stronger the resentment, the stronger the power. They have completely exterminated human nature. They only know how to kill and devour, and there is almost no obedience at all.
There are also creations that God Race labeled as "failures", and the life forms made Lin Fei feel surprisingly familiar: werewolves and vampires!
It is also the transformation of human beings, resulting in the creation of mutations, but in the eyes of God Race, they are complete failures, waste, and garbage.
Their growth limit is low, and their weaknesses are ridiculously large. Even the most common silver weapons can cause fatal damage to them, and vampires are also afraid of the sun.
"Is this the origin of vampires and werewolves?" Lin Fei couldn't help but feel surprised. He really didn't expect it to be like this.
But new questions also surfaced.
Arcane Race, Crystal Clan, God Race and other powerful clans were all on the verge of extinction in the era of Lin Fei. Why are "failures" like vampires and werewolves still passed down?
Vaguely, Lin Fei has a mysterious intuition. There must be a huge secret hidden behind it, a secret buried by Multiversal Heavenly Dao!
But in this situation, he didn't think much about it.
"Shadow Demon!" Xiao Shiyu suddenly shouted in surprise.
On the ceiling and walls of this laboratory, there are several black shadow demons, including the shadows of Lin Fei.
They are no longer just in the form of shadows, but a real and special life form, as if they are in a liquid state and will only appear when exposed to light.
Several shadow demons neighed in terror, evaporated instantly under the holy light, and turned into shadows again and returned behind the three of them.
The number of spirit sons of the three people returned to normal, and there was no longer any sign of spirit son transition.
Only the shadow of the Arcane King is protected by the shadow energy and is not invaded by the holy light.
To be kind to your enemies is to be cruel to yourself.
Lin Fei There is no reason to think about him.
"Are you sure this will only happen once?" Lin Fei asked in a deep voice.
"Don't worry, it must only be once! My father said that even if he is a consul, his spirit son jump can only work on the same target once!" Xiao Shiyu said with confidence.
Although she doesn't seem very reliable, it's different when it comes to the King of Nanling.
Heavenly Spirit There is no doubt about the vision and judgment of the strong.
The three of them quickly returned along the long road without any further delay.
"I didn't expect it to be so easy," Xiao Shiyu was in a good mood, smiling brightly and narrowing his eyes like crescent moons, "What a dangerous life-limited area, isn't this quite safe--"
Her voice stopped suddenly, and the smile on her face instantly solidified.
Because at the entrance of the seventh-floor laboratory, like a black tide, a large number of monsters suddenly poured in endlessly.
"Well, yes, we are safe, very safe." Lin Fei sneered and complained, waving the scepter in his hand and bursting out immeasurable holy light.
"Boom--"
The white holy light was extremely brilliant, like a violent torrent, reaching up to the ceiling and down to the ground, filling and submerging the entire passage.
For a time, all kinds of miserable screams and neighs could be heard incessantly, and even the screams were different.
Many monsters instantly evaporated into smoke in the holy light, and their bodies and spirits were destroyed.
"Kill out!" Lin Fei's eyes were sharp and he decided decisively.
There is no other way to go.
The two men displayed their might, and the storm of holy light opened the way, sweeping everything with devastating force.
They were exactly the same, with the agility of a cheetah, they swooped past and went directly to the sixth floor.
And the moment they stepped onto the sixth floor passage, Lin Fei's pupils shrank slightly, and Xiao Shiyu's face turned pale.
Because in their sight, they were full of shadow demons and various mutated life forms, as well as the wronged souls of Sanctuary warriors.
Layers upon layers, even on the walls and ceiling, were crawling with all kinds of ferocious monsters, with their bloody mouths open, roaring sounds, and saliva dripping from their mouths.
He came towards the three people and attacked them.
