What bothers Li Yao most is not the strength of the Youfu army, but the reinforced collar he wears around his neck.

Li Yao saw that in the research room separated by a transparent crystal wall, dozens of collars of the same style were placed on the display shelf, and dozens of strengthening agents of different colors were beside them.

Strengthening potions and collars can be combined freely. In addition to the red potions, there are also light gray, dark purple, dark blue and so on. Each potion has a strange luster and a strong aura.

That is to say, this kind of strengthened collar is very likely not only to stimulate the magic power of fire, but also to stimulate dozens of different kinds of magic power, such as frost, poison, corrosion and so on.

"If all the Youfu troops wear different kinds of reinforced collars, plus" biochemical weapons ", their actual strength will absolutely sweep any major battle group in the Federation!"

The owl dragon skimmed over dozens of research laboratories and weapon test fields one by one. The more he looked, the more startling he was.

Youquan Laozu's strength is far beyond his imagination. His so-called "rise of the third life form" is not a dream, but a terrible future that is very likely to happen!

In front of the passage, are a few just finished the test, a tired Youfu army.

They are walking towards the lift platform at the end of the passage.

In his heart, Li Yao followed these Youfu troops and got into the lifting platform.

On the console of the platform, there is a detector array. A Youfu army sticks his right hand to the detector array. A faint red dark light sweeps through and turns green. Then the platform starts slowly.

Judging from the glitter of the crystal engraved on the lifting platform, the scale of "Youfu" is huge. This building alone has dozens of floors.

They were on the third floor, but now they are on the twelfth floor.

The 12th floor underground is a large-scale training camp. Hundreds of Youfu soldiers are engaged in high-intensity training here. Even soldiers with only three or five demon pills embedded in the Youfu army will bind hundreds of kilograms of weight on their wrists and ankles and practice under three or five times of gravity.

Even so, their boxing power often reaches thousands of kilograms.

When their demon Dan surges out a strong light, even one punch can break through the speed of sound, burst out the force of tens of thousands of Jin, and completely pierce a palm thick steel plate!

This kind of power made Li Yao smack his tongue secretly.

Maybe the new all crystal armor battle group of Xingyao federation can compete with it, but in the same way, Youfu army will be equipped with biochemical war beasts!

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

The temperature in the dark room is extremely low, and it is a dead silence. It is like a large-scale cemetery. In the light of ice mist, there are thousands of deep sleep cabins of different sizes.

"This is... The military deep sleep module of Xingyao Federation, but it has also undergone the same biochemical transformation, with a lot of unidentified blood vessels, biochemical brains and vegetations added on it!"

The four Youfu soldiers found their own deep sleep cabin and lay down in it. On the light screen of the sleeping cabin, the numbers and runes changed quickly. Looking through the crystal observation hole, they were filled with dark blue gas. Frosting soon appeared on the eyelashes and nose tips of the four Youfu soldiers, and they went into hibernation at extremely low temperature.

"I see. Through the transformation, these deep sleep cabins have the effect of" hibernation. "

"But why?"

Li Yao gently knocked his head, thinking, "yes, the demon Dan is an extremely unstable psionic polymer after all. If he is careless, it will leak or explode. He must hibernate every other period of time to stabilize the psionic power in the demon Dan!"

"There are 505 sets of deep sleep cabins here, but it should not be the only camp of Youfu army. It seems that there are two or three similar camps nearby, and there should be one on each floor."

"It is preliminarily estimated that the total strength of the Youfu army should be about 5000 people, which is more in line with the scale of a secret army. No matter how many people there are, the material supply of the Arctic Yinfeng island will be too large, which will increase the possibility of exposure."

Li Yaoyin has a toothache.

The individual strength of Youfu army is far higher than that of Taixu soldiers, and it has all kinds of terrible biochemical magic weapons. Moreover, Youfu army is an intelligent creature with independent consciousness, and there is no possibility that all the soldiers will surrender when a command center is destroyed.

If he can fight any more, it will be the limit to fight dozens or 100 of them. He will never kill 5000 Youfu soldiers.

What's more, there are "crazy doctor" Lu Wuxin, the master of demon Emperor series, and the leaders of black bully and whirlpool, the two quasi demon Emperor series.

Moreover, you Quan may still be here, leaving behind some secret weapons.

"This battle is more complicated than the one against Xiao xuance in the past."

"But..."

Li dazzle Zhu a turn, control Xiaolong in Youfu army resting area over a circle, especially along the deep sleep cabin of various pipelines, follow the vine, found the end of all pipelines.

Each deep sleep module is equipped with dozens of pipelines for different purposes, some of which are responsible for inputting psionic energy into it, while others are responsible for inputting high-energy nutrients into it, so that users of the sleep module can practice in their sleep and recover their body functions instantly.

More importantly, there is a crystal line connecting these deep sleep chambers with the main control crystal brain.

As expected, the lines extended from each deep sleep module finally coalesced and led to deeper underground.

"In this secret base of Youquan Laozu, a lot of magic weapons from Xingyao Federation are used, so besides biochemical brain, he must have a master crystal brain with high level and super computing power!"

"These deep sleep cabins are all controlled by the master brain!"

"Assuming that this base is controlled by a dual core system, with a biochemical brain and a crystal brain 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 whole" Youfu "and dig out all the treasures of Youquan's ancestors!"

It's a pity that there is a perfect fit between the crystal line and the pipe. Even if there is a little gap, it is blocked by biochemical nerves, and the Xiaolong can't get in at all.

Li Yao secretly wrote down all the crystal line layout of the sleeping area, drove the Xiaolong to continue to wait outside the landing platform, and went up and down with several Youfu soldiers when they entered the landing platform.

In this way, it took Li Yao several hours to visit most of the area of the building.

The building is in the shape of a pyramid. It grows bigger and bigger as it goes down. Only the tip of the iceberg is exposed.

On the top are the barracks of Youfu army, and on the bottom are a large test area and weapon test area, where the prison house for the fire ant king is also set.

Next, there are several layers of Youfu army barracks and deep sleep area, and below is the biochemical war beast warehouse.

The thunder Python where Lee Yao is hiding is stored here.

Below the warehouse is a large and highly confidential experimental area.

It's like a lifeless prison. On both sides of the cold corridor are independent prisons, sealed with solid crystal glass. The crystal glass is often reinforced with cross steel beams, and the steel beams are engraved with dense lightning runes. It seems that they are afraid of the prisoners escaping.

In several successive prisons, there were people with pale skin, black eyes and melting pupils.

There are not only standard human beings, but also distinctive demons.

No matter the Terran or the demon clan, they were lifeless and motionless for a long time. They didn't even have chest ups and downs, which made Li Yao doubt whether they had already died.

Several demons in white robes stood outside pointing and recording.

"Chi"

At this time, the door of the lifting platform opened again, and "crazy doctor" Lu unintentionally strode in, with a relaxed and happy expression on his face.

Li Yaowei was stunned. Counting the time, Lu Wuxin should have finished the first torture of the fire ant king.

Hope the nerve of Fire Ant King is strong enough to survive!

"Show me the combat status of test body 66778."

Lu unintentionally said nothing nonsense to a white robed demon tribe.

66778 is a human with thick eyebrows and big eyes.

Next to his left eye, there is a machete tattoo around his eye socket. Li Yao knows that this is a popular tattoo in the Xingyao federal army, which means that this human is an expert in playing with knives.

However, his face was gray and covered with body spots, and he didn't breathe for more than half an hour.

What's more, there was a big hole in his left chest. He could see his back directly. He had already died and could not die any more.

The more he clenched his fist, the tighter he became.

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

Above the cell, an iron cage was slowly suspended. As soon as the prohibition around the iron cage was removed, "bang", the wire mesh was torn to pieces, and a dog like monster with scorpion tail sprang out.

"Scorpion wolf!"

Li Yao recognized at a glance that the scorpion wolf was not a monster with a very high level, but it was extremely fast. The tail of the Scorpion was highly poisonous, and it was very alert, which was quite difficult to deal with.

Scorpion wolf is a kind of depraving monster. Seeing a corpse curled up in the corner, his eyes lit up and he barked twice. He rushed to the corpse of the Union soldier.

Unexpectedly, at the moment when the scorpion wolf leaped up, the eyes of the Union soldiers suddenly seemed to be injected with a touch of scarlet venom, and the body suddenly bounced up in a rigid posture!

"Hiss!"

The mouth of the Union soldier cracked to the root of his ear, and his jaw pulled to his chest. A poisonous fog spewed out from the depth of his throat, forming a bright red beam of light, instantly penetrating the scorpion wolf from head to tail.

The scorpion wolf, famous for his agility, even had no time to dodge and died on the spot!

But after finishing the blow, the soldiers of the Federation seemed to have exhausted the last drop of power in the cell, and the body was withering away at the speed that the naked eye could see, especially in the abdomen, like a whirlpool, and the body was fast foaming.
