However, Li Yao did not let Neltharion pass through the diamond-shaped grid of the ventilation tube recklessly. Instead, he triggered a probe mystic ray and adjusted the frequency of the mystic ray while he scanned the diamond-shaped grid.
As he expected, when he adjusted the mystic ray to a very low frequency, dozens of mysterious demonic lights appeared on the diamond-shaped grid, which were moving randomly and disorderly.
Once Neltharion touched the crimson demonic lights, the alarm system would certainly be triggered.
The defense is quite thorough!
Li Yao asked Neltharion to stop below the entrance of the ventilation tube for five seconds while he calculated the speed of the demonic lights and the changing angles of the gaps quickly.
Five seconds later, Neltharion passed through the diamond-shaped grid unhurriedly like a lazy goldfish. The crimson demonic lights seemed to be telepathic with Neltharion and cooperated well with it. They brushed past Neltharion dangerously with only a hair's breadth between them!
Neltharion passed through the demonic lights and invaded the ventilation tube!
What he saw inside the ventilation tube, however, greatly surprised Li Yao.
There was no impenetrable scanning defense system as he had imagined. Instead, the wall of the tube was full of flying insects. In the corners of the tube, there were tiny spider webs where colorful spiders were lurking in the darkness.
The flying insects, the spiders, and the dark gray dwarf vampire bats that seemed to have been melted into the tube constituted a complete ecosystem of the ventilation tube.
Li Yao could not help but click his tongue. Even if somebody had compressed their muscles and bones to the minimum and crawled into such a tube, they would not have been able to do anything when faced with the dense insects.
Even the small biochemical beasts would not have been able to sneak into the place without alarming the insects.
Elder Nether Spring is indeed an expert on insects. I'm afraid that the defense of this place is even more thorough than that of the Supreme Council of the Xing Yao Federation.
Thankfully, Li Yao had Neltharion, a piece of magical equipment refined in the peak era of the Star Ocean Imperium!
Neltharion remained invisible and floated at the center of the tube, observing the functioning of the ecosystem in silence.
The flying insects that looked like mosquitoes were on the wall of the tube. They were flying irregularly at every moment, catching the floating particles in the air as food.
There were also many mosquitoes that would stick to the spider web. When the "food" accumulated to a certain extent, the colorful spiders would move out. It devoured all the food on the spider web.
At that time, the mosquito would be obedient for a few seconds, revealing a crooked gap.
That was Li Yao's only chance!
He patiently waited for the spiders to come out. After three hunts, he calculated the average time that there was a gap between the mosquitoes. When the spider moved out for the fourth time, he drove Neltharion forward!
He could not be too fast. Otherwise, the flow of air would be affected and he would be discovered. The black fog made of mosquitoes was like a bloody mouth that slowly closed behind Neltharion. The 'tusks' almost pierced into Neltharion's bottom.
In front of them, the entire pipe was sealed off by a spider web. The shiny spider silk was smeared with a deadly mucus.
Fortunately. The holes in the spider web were not uniform, especially when larger prey struggled violently, they would tear the web apart.
The colorful spiders, after swallowing enough food, began to repair the spider web.
Li Yao held his breath and looked for the largest hole patiently.
It was a great test for his skills in piloting a starship, too.
At first glance, the hole he found was almost identical to the diameter of Neltharion. A slight tremor during the passage might have wasted all his previous efforts.
The colorful spiders. Instead, he crawled towards the hole and prepared to fix the biggest hole first.
"Take it slow. Relax. There's still a lot of time. Also … "
Neltharion jumped softly and passed through the spider before it spat out the first thread!
Li Yao took a long breath in relief. He almost melted into the stomach of the thunder boa.
Then, he passed through the blockage of the seven layers of spider webs in the same way. Finally, he reached the entrance of another ventilation tube.
Looking down through the diamond-shaped grille, he could vaguely see that it was an enormous laboratory or factory.
The spacious space had been divided into quite a few different areas. Below Neltharion, it turned out to be a weapon test area.
A slender soldier of the Nether World Watch with a head that looked like a wolf was aiming at Li Yao with a narrow, long, bizarre-shaped gun magical equipment in his hands.
"This is the sniper version of the 'Wild Tide VII' storm bolter!"
Li Yao recognized after a glance that the guy was using an assault rifle that was very popular in the Xing Yao Federation. After the high-precision components were installed, it could be transformed into a general-purpose sniper rifle with decent performance parameters.
However, other than the high-precision components, the 'Wild Tide VII' was also entangled with thick veins and tentacles. Around the box of spiritual energy were two excrescences that looked like tumors. Two crimson eyeballs protruded out of the left and right sides of the scope!
It seemed to have been infected, assimilated, and swallowed by a certain abnormal monster, turning it into a weird weapon that was half magical equipment and half life, similar to the blood-sucking flying swords that Li Yao had seen in the Mausoleum of Chaos!
What was even more terrifying was that almost ten 'veins' or synthesized nerves were growing out of the sniper rifle and piercing into the arms, chest, and temples of the sniper of the Nether World Watch, as if he had been melded with the weapon!
"Manipulating the magical equipment by means of direct neuron control? In such a case, it will be easy for me to use it without too much telepathic thoughts, and its performance will be significantly improved, too!
Li Yao thought to himself.
Hu! Hu! Hu!
A strong wind was blowing around the test field. There were even artificial snowflakes, which seriously affected the sniper's vision and senses.
According to the drill of the Union Army, such weather was highly unsuitable for sniping.
But the sniper of the Nether World Watch did not move at all. He was still kneeling like a cold statue.
Beep!
Hundreds of meters away, a blue fountain gushed out and scattered flowers in the air, turning into dozens of blue starlights.
Hiu! Hiu! Hiu! Hiu!
The sniper of the Nether World Watch was shooting steadily. He even changed his shooting position after five shots. He had changed his shooting position six times in only half a minute. The interference of the wind and the snowstorm did not affect him at all. None of his bullets missed their targets. The dozens of blue stars died out all of a sudden!
Li Yao was secretly shocked.
"The sniper version of the 'Wild Tide VII' assault rifle that has been secretly modified by Elder Nether Spring has been significantly improved in terms of firing speed, loading capacity, stability, and anti-interference ability. The comprehensive performance parameters have been improved by at least 35%!
What is even more dreadful is that it is not just the bullets of spiritual energy that it can trigger but also a cluster of fatal venom!
I'm afraid that it is the function of the two excrescents that look like tumors next to the box of spiritual energy. They are the venom sacs!
Li Yao could totally imagine the purpose of such a design.
First of all, the bullets of spiritual energy, which were highly penetrative and destructive, would destroy the shield, shell, and plate armor of the target and expose the most vulnerable internal parts of the target.
Then, the venom or acid would directly destroy the exposed personnel and the internal organs!
It was an extremely vicious weapon for both human beings and demons!
Since the sniper rifle has been modified in such a way, the assault rifle, which is simpler in structure, must have been modified in the same way a long time ago.
The soldiers of the Nether World Watch whose bodies are embedded with demon cores are already tricky enough. If they are all equipped with such powerful weapons, the outcome will be unimaginable!
Li Yao memorized the performance parameters of the 'biochemical sniper rifle' and left quietly on Neltharion.
In the second test field was a tall and muscular soldier of the Nether World Watch. More than ten bullet chains were tied up around him, on which crimson grenades were dangling.
Li Yao noticed that the man was wearing a special collar on his neck that was as thick as a tree trunk. A special dark red drug was stored inside the collar.
Chi! Chi!
The thin needles on the inside of the collar pierced into the soldier's neck softly. The dark red drug was all injected into his body.
Aooo! Aooo! Aooo!
The soldier of the Nether World Watch burst out a deafening roar. His skin was breaking apart, and intense flames were flowing out of his crimson skin!
Very soon, he turned into a fiery demon almost ten meters tall. The flames turned from red to white, and the temperature was higher and higher, making him look like a cluster of molten steel!
What was weird was that, despite the high temperature, the soldier of the Nether World Watch did not die but charged at a heavy crystal tank that was serving as a target.
The heavy crystal tank, under the remote control of the staff nearby, roared and charged at him, too!
BOOM!
The fiery demon of the Nether World Watch was like a crazy rhinoceros. Every step he took left a deep footprint on the ground. At the highest speed, he blocked the heavy crystal tank like a shooting star. The two parties resisted each other for three seconds. Then, smoke popped up from the bottom of the heavy crystal tank. It had been pushed away by the fiery demon!
"Chi!"
The fiery demon of the Nether World Watch leaped forward. His hands seemed to have turned into two sabers of fire as he stabbed them into the reactive armor of the crystal tank brutally.
Under the burning of the high-temperature flames, the reactive armor was blown apart and torn apart as easily as a piece of paper, leaving a basin-sized hole behind.
The muscular soldier of the Nether World Watch took off almost ten grenades from the bullet belt and threw them into the crystal tank, before he blocked the hole with his chest.
BOOM! BOOM! BOOM!
BOOM! BOOM! The crystal tank bounced up as if it had been installed with springs. The entire turret flew into the sky. The muscular soldier of the Nether World Watch was blown dozens of meters away by the immense blast, too. But he quickly rose to his feet and brushed the smoke on his chest while he chuckled in a low voice.
"One such monster is enough to cause great trouble for an armored battalion of the Federation. Even if the armored battalion has its own Cultivators, it will still be difficult for them to deal with it.
