However, instead of letting the Xiaolong rashly pass through the rhombic grid of the ventilation duct, Li Yao first excited a beam of dark light to detect, constantly adjusted the frequency of the dark light, and scanned the rhombic grid.

Sure enough, when he adjusted the dark light to a very low frequency, dozens of mysterious demon lights appeared on the diamond grid, crisscrossing, disorderly and moving irregularly.

Once the owl dragon touched these scarlet lights, it would trigger the alarm system.

"The defense is very tight!"

Li Yao asked Xiaolong to stay under the ventilation duct for five seconds, and quickly calculated the moving speed of demon light and the changing angle of the gap.

Five seconds later, the owl dragon slowly passed through the diamond grid, like a lazy goldfish, a scarlet demon light, as if with its heart, with a tacit understanding, with a hair gap, dangerous and dangerous pass!

The owl dragon penetrates the demon light and invades the ventilation duct!

The scene inside the ventilation duct surprised Lee.

There is no magic light scanning defense system in the imagination, but the wall of the pipe is full of flying insects. At the corner of the pipe, there are extremely thin cobwebs, colorful spiders, dormant in the dark.

Flying insects, spiders, and dark gray dwarf blood sucking bats, which seem to be integrated with pipes, form a complete ventilation pipe ecosystem.

At a loss what to do, Li Yao could not help but even if someone really had to limit their muscles and bones to the limit. If they were to drill into such a pipeline, they would be helpless to face the * dense insects.

Even small biological warfare animals can not invade unnoticed * without disturbing these insects.

"You Quan is really an expert in insect playing. I'm afraid the defense here is tighter than the Supreme Council of Xingyao Federation."

Fortunately, Lee Yao has the magic weapon refined at the peak of the Xinghai Empire, Xiaolong!

Xiaolong continued to remain invisible, suspended in the middle of the pipeline, silently observing the operation of the whole ecosystem.

On the wall of the tube, small flying insects, like mosquitoes and midges, are flying irregularly all the time, capturing the floating particles in the air as food.

There are also many mosquitoes and midges will stick to the spider web. When the "food" accumulates to a certain extent, colorful spiders will come out and devour all the food on the spider web.

At that time, mosquitoes and midges would be a little honest for a few seconds, revealing a zigzag gap.

That's Lee's only chance!

He patiently waited for the spider to come out and hunt for three times, and calculated the average time of the gap between mosquitoes and midges. When the spider went out for the fourth time, he drove the owl dragon and rushed past!

His speed must not be too fast, otherwise it will interfere with the flow of air, and it will also be found that the black fog composed of mosquitoes and midges is like a bloody mouth, slowly closing behind the Xiaolong, and the "fangs" will almost plunge into the buttocks of the Xiaolong.

In front, the spider web blocked the whole pipe, and the shiny spider silk was smeared with deadly mucus.

Fortunately, the holes in the web are not uniform, especially when some larger prey are struggling fiercely, they will tear the web.

Colorful spiders, after swallowing enough food, begin to repair their webs.

Li Yaoping kept breathing and patiently searched for the biggest hole.

This is also a great test of his skill in controlling the Starship.

At first glance, as like as two peas, the hole he found was exactly the same as the size of the dragon, and a slight tremor in the course of crossing would probably give up all the work.

The colorful spider crawled to the hole, ready to repair the biggest hole first.

"Take your time, relax, there's still a lot of time, and..."

The owl dragon, with a slight leap, successfully crossed before the spider spit out its first wisp of silk!

Li Yaochang breathed a sigh of relief, and his whole body almost melted into the stomach of thunder python.

Next, he did the same, through the seven cobweb blockade, and finally arrived at another ventilation duct entrance.

Looking down through the diamond grille, you can see that it is a huge laboratory or factory.

The huge space is divided into several different areas. Under the Xiaolong, there is a weapon test area.

I saw a thin, jackal like head of the Youfu army, holding a long, thin, strangely shaped weapon, aiming at him in a kneeling position.

"This is the sniper version of the Nu Tao-7 psionic arrow blaster!"

Lee yew recognized at a glance that the other side was using an assault rifle which was very popular in the Xingyao Federation. After adding a high-precision kit, it can become a general-purpose sniper gun with good performance parameters.

However, in addition to the high-precision kit, the surface of the handle "Nu Tao-7" is also wrapped with thick blood vessels and flesh touch. Around the power box, two tumor like vegetations are attached, while the left and right sides of the sight highlight two scarlet eyeballs!

It's like being infected, assimilated and devoured by some kind of deformed monster. It has become a half magic weapon and half life strange weapon similar to the blood sucking flying sword seen by Li Yao in the chaos tomb!

What's more terrifying is that from this sniper gun, seven or eight "blood vessels" or synthetic nerves were born, which deeply penetrated into the arms, chest and temples of the sniper, as if integrating him with this weapon!

"How to control this magic weapon by means of neuron direct control? In this way, it can be easily controlled without too strong ideas, and the performance will be greatly improved! "

Li Yao thought in secret.

"Hoo! Whoo! Hoo

Around the test site, there were strong winds, and even artificial snowflakes, which seriously interfered with the sniper's vision and perception.

According to the Federal Code of conduct, such weather is not suitable for sniping.

The sniper of Youfu army, however, did not move. He still kept his kneeling position, just like a cold statue.

"Didi!"

Hundreds of meters away, a faint blue fountain came out. In the mid air, tiannu scattered flowers and turned into dozens of blue stars.

"Whew! Whew! Whew! Whew

The sniper of Youfu army shot calmly. Even after five times of shooting, he moved one shooting position and changed six shooting positions in half a minute. The interference of gale and blizzard had no effect on him. He almost shot in vain. Dozens of blue stars suddenly went out!

Li Yao was secretly frightened.

"The sniper version of the nutao-7 assault rifle, which has been secretly improved by Youquan Laozu, has greatly improved its firing speed, ammunition load, stability and anti-interference performance compared with the original version, and its comprehensive performance parameters have been improved by at least 35%!"

"What's more, it's not only a psionic bomb, but also a bunch of deadly venom!"

"I'm afraid that's what the two tumor like vegetations next to the psionic box do. They're venom sacs!"

Lee can fully imagine the use of this design.

First of all, use penetrating and destructive psionic bombs to destroy the target's shield, shell and armor, exposing the most vulnerable interior.

The following poison or acid can directly destroy the naked people and viscera!

No matter for the Terran or demon clan, they are extremely vicious weapons!

"Since even sniper guns have been transformed in this way, assault rifles with simpler structure must have been transformed in the same way long ago."

"The Youfu army, which is covered with demon Dan, is very difficult. If they are all equipped with such powerful weapons, it's unimaginable!"

Li Yao kept in mind the performance parameters of this "biochemical sniper gun" and steered the Xiaolong to leave quietly.

In the second test field, there was a strong man of Youfu army. He was surrounded by more than ten bullet chains, which were hung with red palm thunder.

Li Yao noticed that on his neck, which is as thick as a tree trunk, he was wearing a special collar in which a special dark red medicine was stored.

"Hiss

The thin needle on the inside of the collar gently pierced the neck of the Youfu army. All the dark red medicine was injected into the body.

"Ouch, ouch, ouch!"

This military explosion of Youfu sent out an earth shaking roar. His skin was cracked, and there was a strong flame under his red skin!

He soon turned into a three or four meter tall fire devil, the flame from red to white, the temperature is getting higher and higher, like a lump of molten steel!

Strangely, in such a high temperature, the Youfu army didn't die, but rushed to a heavy crystal chariot as a target.

The heavy crystal chariot, under the remote control of the staff nearby, roared with all its strength and rushed towards him!

"Boom!"

The weapon demon of Youfu is like a crazy rhinoceros. Every step marks a deep footprints on the ground, and its speed soars to the limit. It's like a meteor running wild. It holds the heavy crystal chariot hard. After fighting for three seconds, the heavy crystal chariot's buttocks emit plumes of smoke, and he pushes it out!

"Chi!"

The weapon demon of Youfu leaps up, and his hands seem to be turned into two flame swords, penetrating the reactive armor of the crystal chariot.

Under the burning of the high heat flame, the reactive armor, like a piece of paper, was easily exploded and torn by him, revealing a hole the size of a washbasin.

The strong man of Youfu army took off seven or eight palm thunder from the bullet chain, threw them into the crystal chariot, and blocked the hole with his chest.

"Boom! Boom, boom

The crystal chariot jumped up like a spring, and the whole turret flew up into the sky. The strong man of Youfu army was also blasted out dozens of meters away by the powerful impact force, but he got up, dusted the smoke from his chest, and gave out a deep laugh.

"Such a monster, as long as it has one head, can cause great trouble to an armored battalion of the Federation. Even if the armored battalion has its own battalion of practitioners, it is extremely difficult to deal with it."

"If it's used to attack fixed firepower points and destroy the city and pull out the stronghold, such monsters will be more sharp. It's impossible to equip a practitioner in every firepower point, right?"
