What bothered Li Yao the most was not the strength of this Youfu army, but the strengthened collar he wore around his neck.

Li Yao saw that in the research room separated by a transparent crystal wall, there were dozens of collars of the same style on the display shelves, and next to them were dozens of strengthening potions of different colors.

Enhancement potions and collars can be freely combined, in addition to the crimson elixir, there are light gray, dark purple, dark blue, etc., each elixir, exuding a strange luster, rippling with a rich aura.

In other words, this kind of strengthened collar is very likely to not only stimulate the flame supernatural power, but also stimulate dozens of different supernatural powers such as frost, Gu poison, corrosion, etc.

"If all the Youfu Army wears reinforced collars of different natures, coupled with the 'Biochemical Firearms', its strength will definitely sweep through any of the main battle groups of the Federation!"

The Thunder Dragon swept over dozens of research laboratories and weapons testing sites one by one, and the more Li Yao looked at it, the more shocking he became.

The strength of the Youquan Ancestor is far beyond his imagination, and his so-called "rise of the third life form" is indeed not a fool's dream, but a terrifying future that is very likely to happen!

On the passage ahead, there were several Youfu soldiers who had just finished the test and were tired.

They were walking towards the lifting platform at the end of the passage.

Li Yao's heart moved, and he followed these Youfu troops and got into the lifting platform.

On the console of the lifting platform, there was a detection talisman array, and a Youfu army put his right hand on the detection talisman array, and a pale red light swept over and turned green, and the lifting platform slowly started.

Judging from the spar flickering engraved on the lifting platform, the scale of the "Youfu" is extremely large, and there are dozens of floors in this building alone.

They were just three floors underground. At this moment, he came to the twelfth basement floor.

The twelfth floor underground is a huge training camp, where hundreds of Youfu soldiers are carrying out high-intensity cultivation, even the soldiers in the Youfu army who are only inlaid with three or five demon pills will tie hundreds of kilograms of weight to their wrists and ankles. Cultivate under three or five times the gravity.

Even so, their punches often reach thousands of kilograms.

When a strong light erupted in their demon pill, they could even break through the speed of sound with one punch, bursting out with a force of tens of thousands of catties, completely penetrating a palm-thick steel plate!

Such a power made Li Yao secretly smack his tongue.

Maybe the newly formed all-crystal armor wargroup of the Star Federation can compete with it, but by the same token, the Youfu Army will inevitably be equipped with biochemical war beasts!

Several Youfu soldiers entered a dark room next to the training camp.

The temperature in the darkroom is extremely low. There was a dead silence, like a cemetery on a grand scale, and in the faint ice mist, thousands of deep sleep pods of various sizes stood.

"It's ...... The military deep sleep pod of the Star Federation has also undergone the same biochemical modification, adding a lot of blood vessels, biochemical brains and vegetations of unknown use on it! ”

The four Youfu soldiers found their deep sleep pods and lay down in them. On the light curtain on the surface of the sleeping pod, numbers and runes changed rapidly. Looking through the crystal observation hole, it was quickly filled with dark blue gas, and frost flowers soon appeared on the eyelashes and nose tips of the four Youfu soldiers, and they instantly entered a state of extremely low temperature hibernation.

"Understood, through modification, these deep sleep pods have a similar effect to 'hibernation'."

"But. Why? ”

Li Yao tapped his head lightly, thoughtfully, "Yes, after all, the Demon Pill is an extremely unstable spiritual energy aggregate, and it will leak or explode if you are not careful. It is necessary to enter a state of hibernation every once in a while to stabilize the spiritual energy in the demon pill! ”

"There are a total of five hundred and five deep sleep pods here, but it shouldn't be the only camp of the Youfu Army, there seem to be two or three other camps of the same kind next to it, and there should be more on the upper and lower floors."

"It is preliminarily estimated that the total strength of the Youfu Army should be around five thousand, which is also more in line with the size of a secret army, if there are more people, the supply of materials from the Arctic Yin Wind Island will be too large, which will increase the possibility of exposure."

Li Yao faintly had a toothache.

The individual strength of the Youfu Army is far superior to that of the Taixu soldiers, and it has all kinds of terrifying biochemical magic weapons, and the Youfu Army is an intelligent creature with independent consciousness, and there is no possibility of disarming and surrendering after being knocked out of a command center.

No matter how much he can fight, it is the limit to fight dozens or a hundred of them, and it is impossible to kill all the 5,000 Youfu troops.

What's more, there is also the "mad doctor" Lu Wuxin, the master of the Demon Emperor level, as well as the two quasi-demon emperor level leaders of the Black Tyrant and the Vortex.

Moreover, Youquan Ancestor may still be here, leaving behind some secret weapon.

"This battle is more complicated than the battle against Xiao Xuance in the past!"

"But ......"

Li Yao's eyes rolled, and he manipulated the Thunder Dragon to go around the rest area of the Youfu Army, especially along the various pipelines of the deep sleep cabin, and found the end of all the pipelines.

Each deep sleep pod is equipped with dozens of pipelines for different purposes, some of which are responsible for injecting spiritual energy into it, while others are responsible for injecting high-energy nutrients into it, so that the users of the sleeping pod can be cultivated in their sleep and their body functions can be restored instantly.

What's more, there is also a crystal wire that connects these deep sleep capsules with the main control crystal brain.

As expected, the lines that extended from each of the deep sleep pods eventually coalesced together and led deeper underground.

"In this secret base of the Youquan Ancestor, a large number of magic weapons from the Star Federation are used, so in addition to the biochemical brain, he must also have a high-level and super-powerful main control crystal brain!"

"These deep sleep pods are all controlled by the main control crystal brain!"

"Assuming that this base is controlled by a 'dual-core control', with a biochemical brain and a crystal brain being controlled in parallel, they will not be too far away, and they are likely to be installed together."

"As long as you find these two 'brains', you can control the entire 'Youfu' and dig out all the bezoar dog treasures of the ancestor of Youquan!"

It's a pity that the crystal line and the pipeline are tightly connected, and even if there is a gap in the slightest, it is tightly blocked by the biochemical nerve, and the Thunder Dragon can't get into it at all.

Li Yao secretly wrote down the layout of all the crystal lines in the sleeping area, and continued to wait outside the door of the lifting platform with the Thunder Dragon, taking advantage of the fact that several Youfu soldiers entered the lifting platform, and went up and down with them.

In this way, Li Yao spent several hours walking around most of the area of the building.

The building is pyramid-shaped, getting bigger and bigger the further down it goes, and only the tip of the iceberg is exposed.

The top few floors are the barracks of the Youfu Army, and below is a large test area and weapon testing area, where the torture chamber where the Fire Ant King is imprisoned is also located.

Next are several floors of the barracks and deep sleep areas of the Youfu Army, and below them are the biochemical war beast warehouse.

The Thunder Python where Li Yao was hiding was stored here.

And underneath the biochemical war beast warehouse is another large-scale, highly classified test area.

It was like a lifeless prison, with separate cells on both sides of the cold corridor, sealed with solid crystal glass, which was often reinforced by crossed steel beams, which were engraved with dense thunder and lightning runes, as if they were afraid that the prisoners inside would escape.

In several prisons in a row, there were people sitting or lying with gray skin, black eyes, and pupils that seemed to melt.

There are both standard humans and distinctive demon races.

Both the human race and the demon race were lifeless, not moving for a long time, and even their chests did not rise and fall, which made Li Yao wonder if they were already dead.

Several demon clans in white robes stood outside and pointed, burying their heads in recording something.

"Uhhh

At this moment, the door of the lifting platform opened again, and the "mad doctor" Lu Wuxin strode in, with a relaxed expression on his face.

Li Yao was slightly stunned, calculating the time, Lu Wuxin should have completed the first torture of the Fire Ant King.

Let's hope the Fire Ant King's nerves are strong enough to survive it!

"Show me the combat status of Subject 66778."

Lu Wuxin didn't talk nonsense, and said bluntly to a white-robed demon clan.

Subject 66778 is a human with thick eyebrows and big eyes.

Next to his left eye, there was also a scimitar tattoo around the eye socket, Li Yao knew that this was a popular tattoo in the Xingyao Federation army, representing that this human was an expert in playing with knives.

However, the man's face was gray and covered with corpse spots, and he did not breathe for more than half an hour.

What's more, there is a large hole in his left chest, which can directly see his back, and he is already too dead to die.

Li Yao's fists clenched tighter and tighter.

Even if he died, he didn't want a federal soldier to be so insulted by the enemy!

Above the cell, an iron cage was slowly hung down, and the prohibition around the iron cage had just been removed, and with a "bang", the barbed wire was torn to pieces, and a canine monster with a scorpion poisonous tail came out.

"Scorpion wolf!"

Li Yao recognized at a glance that the scorpion wolf was not a high-level demon beast, but it was extremely fast, the scorpion tail was highly poisonous, and it was very alert, which was quite difficult.

The scorpion wolf is a scavenging demon beast, and when he saw a corpse curled up in the corner, his eyes lit up at the moment, and he barked twice, and then pounced on the corpse of the federal soldier.

Unexpectedly, at the moment when the scorpion wolf jumped up, the pure black eyes of the federal soldiers suddenly seemed to be injected with a touch of scarlet venom, and their bodies bounced up violently in a stiff posture!

"Shhh

The Federal soldier's mouth was split to the base of his ear, his jaw was pulled to his chest, and a puff of poisonous mist erupted from the depths of his throat, condensing into a bright red pillar of light, instantly piercing the scorpion wolf from head to tail.

The scorpion wolf, known for his shrewdness, didn't even have time to dodge and died tragically on the spot!

It's just that after completing this blow, the Federation soldier also seemed to have exhausted the last drop of strength in his cell, and his body withered at a speed visible to the naked eye, especially his abdomen, which was concave like a whirlpool, fell to the ground on his back, and his body quickly foamed.
