Countdown, 25 seconds!

The Xiaolong shot all photos of the military restricted area from all angles, including the fixed patrol routes of the two patrol teams, and were transmitted to Li Yao's brain for modeling.

Li Yao’s main concern is what if the patrol team changes the patrol route halfway?

Jin Xinyue once said that in the standard warning script of the Wan Yao Alliance, each patrol team will set up three to four different patrol routes, which will change once in half an hour or an hour.

If Li Yao and Fire Ant King have more time to observe, you can see the rules of changing patrol routes.

But they only have a few minutes of preparation time and can only try their luck.

Once the other party really changes the course, Li Yao must be prepared.

Based on the terrain in the military restricted area, he precalculated the twenty-three changes that the patrol could make, and determined that he had a minimum time of only 7 seconds.

Countdown, 15 seconds!

The Fire Ant King took out a very delicate cylinder engraved with demon patterns from his arms, and gently spun it away. Two beetles with black bodies all over the body and a green vertical pattern grew from behind.

Under the control of the Fire Ant King, the two beetles flew higher and higher, crossed the high wall outside the military restricted area, and flew ahead of the entrance to the No. 2 ventilation duct.

Countdown, 5 seconds!

Li Yao took off his clothes disguised as a secret treasure merchant and changed into a new set of filmed war suit.

This suit is as thin as a cicada's wings, and it is like a second layer of skin, with almost no gap at all, and the direction of each bunch of muscles is fully highlighted.

"Swish!"

Li Yao touched a rune on the waist of the battle suit. Ripples appeared on the surface of the light gray battle suit, gradually becoming translucent, and finally seemed to melt into the air, making him completely invisible!

This is an expert of the Chaos Blade Organization. It modifies the cell invisible cloak by extracting various monster cells such as chameleons, silverfish, green leaf bamboo insects, etc. that have color-changing, mimicry and transparent magical powers.

When still, it is extremely difficult to detect, like ice thrown into water.

The only disadvantage is that the components that make up the invisible pellet of cells are all highly active and need to be stored in a special culture medium. Once taken out and exposed to the air, the lifespan will not exceed five minutes.

Basically, after four and a half minutes, the invisible clothing gradually became invalid.

On the other hand, this invisible cloak only has the best effect when it is still. When it moves at high speed, it will still leave behind afterimages, causing the air to appear strangely distorted.

Countdown, 0 seconds!

Li Yao floated out like a wisp of smoke.

"Swish!"

He keenly sensed the thermal ray network on the high wall of the military restricted area, but it contracted the bones and muscles all over his body to the limit, not much bigger than a cat, and drilled into the gap in the thermal ray network!

Two patrol teams were heading in the opposite direction of the No. 2 ventilation duct. Li Yao calculated the time they returned. While observing the scanning angles of several biochemical monitoring eyes at a height, he moved around in the dead corner of the needle tip. He quickly approached the target.

Just then—

One of the patrol teams, before reaching the end of the military restricted area, turned back in advance and changed a new patrol route!

"Damn it!"

It is indeed the second patrol plan!

Li Yao stopped moving instantly, his heartbeat and breathing were suppressed to the limit, and even his pores were completely locked. He did not release a trace of heat and breath, and watched the patrol team come towards him.

As long as it is guaranteed to be absolutely still, the invisible clothing can work, and the invisible time is five minutes, which is enough!

The patrol team passed by Li Yao. The soldier closest to him could touch Li Yao's head as long as he stretched his waist.

Fortunately, they did not notice that the air was so close that it was a slight twist.

Even half a minute after they walked over, Li Yao still remained motionless, relying on the Xiaolong to observe their brand new patrol route.

After changing into the second set of patrol lines, the blind spots of the two patrol teams were completely different from those just now, and everything had to be recalculated.

After silently calculating for one minute and two seconds, Li Yao started again!

Deep in his brain, the biochemical surveillance eyes above his head, the two patrol teams, together with twenty or thirty eyes, seemed to emit red rays with substance, forming crisscrossing dead lines in front of him.

The dead line kept changing, and he danced gracefully, sometimes fast and sometimes slow, sometimes advanced and sometimes retreated. It took more than three minutes before he could move to the front of the entrance of the No. 2 ventilation duct with difficulty.

At this moment, there was only one last minute left before the invisible cloak was invalid.

In order to transport air to the underground main body of the huge Blood Demon Eye, each ventilation duct is about one foot in diameter, and a medium-sized adult can barely squeeze in.

However, the entrance of the ventilation duct is covered with a very fine barbed wire mesh, and there is a warning talisman array that is not cut around.

Li Yaofei glanced quickly and understood the operating principle of the alert talisman array. It should be to send an alarm by perceiving vibration.

Once external force forces forcefully break the barbed wire, abnormal vibration will definitely be heard, and as long as it is sensed, an alarm will be issued.

"Swish, swish, swish!"

Inside the barbed wire, half a meter deep into the pipe, three huge fan blades rotated rapidly at a speed of 1,500 revolutions per minute. The fan blades were also engraved with an offensive wind talisman array, rolling up a sharp wind blade, turning this piece of pipe into an invisible meat grinder.

There are 45 seconds left before the Invisible Cloak is completely invalid.

"Sizi, sizi!"

Li Yao sensed that the invisible jacket gradually felt a stiff and stagnant feeling.

This is a sign that invisible cells are about to wither.

At this moment, both patrol teams had all walked to the farthest distance from him, and all the biochemical surveillance eyes were scanning other areas.

However, after this route adjustment, Li Yao only had 11 seconds left!

"Enough!"

Li Yao's hands instantly turned into two grey mist. He first gently absorbed four magnet-like magic weapons next to the warning talisman array. The four magic weapons formed a temporary loop, which was equivalent to temporarily introducing the warning talisman array into a "fork" to make it ignore the subtle vibrations on the wire mesh.

Immediately afterwards, Li Yao carefully scraped off a large amount of rust from the barbed wire mesh with an extremely sharp bone blade and put away all of the rust.

It took Li Yao three seconds to finish all this.

Next, he drew a circle on the barbed wire, cut the barbed wire silently, and drilled in!

It is not difficult to break the barbed wire, the hardest thing is to restore it to its original state!

The patrol team at the farthest part of the military restricted area began to turn around, and the two biochemical surveillance eyes gradually turned their perspective back, and were about to lock the entrance of the No. 2 ventilation duct.

Li Yao's ten fingers were like ten boneless snakes, and there was a fine needle like cow hair between the two fingers.

These fine needles are hollow, and there is a small liquid sac behind them, storing traces of natural adhesive, which were originally used to fix the components of ultra-micro magic weapons.

Li Yao manipulated the tiny muscle bundles on his fingers, squeezed out the glue with a fine needle, and re-glued the short holes of the barbed wire mesh together. He deliberately overflowed some glue on the edge of the bonding, and then blew the rust that had just been scraped off.

Finally, he took out a can of spray and sprayed it gently on the wire mesh.

Suddenly, a thin layer of dust appeared on the surface of the "rusty" barbed wire mesh, and even strands of broken wire like spider webs.

At first glance, it was seamless and there was no trace of being forcibly broken.

Only then did Li Yao use his spiritual energy to hook four "magnets" into the hole in the barbed wire, allowing the warning talisman array to return to normal circuits.

"Swish!"

The biochemical monitoring eye swept through the entrance of the No. 2 ventilation duct and no abnormalities were found.

But the lifespan of the invisible cloak on Li Yao also reached its limit, and twisted light spots began to appear.

Once the patrol approaches, you will definitely find vague gray shadows behind the barbed wire.

The two black beetles of the Fire Ant King followed Li Yao and crashed into the high-speed rotating fan!

This fan has a fast speed and strong suction force, and often sucks in some small flying insects.

These two black beetles were the "green oil fireflies" carefully prepared by the Fire Ant King. They hit the fan blade hard, and made two "" sounds, and two small fireballs exploded!

These two fireballs interfered with the wind-type talisman array on the fan blade. The fan's self-protection mechanism was activated, and a short speed drop occurred, and small foreign objects began to be eliminated.

Li Yao took this opportunity to widen his eyes, his pupils kept trembling, seeing every detail of the fan rotation, and also sensing the wind blades that were invisible to the naked eye.

"Swish!"

He successfully drilled into the gap of the fan blade at 780 revolutions per minute!

Three wind blades cut hard on him, but he locked the muscles all over his body, leaving no blood behind.

After half a second, the fan speed returned to 1500 rpm, and the patrol team happened to reach the entrance of the same pipeline No. 2.

They were attracted by the sound of the bursting of the green oil fireflies, and they looked inside through the barbed wire with some suspicion.

The fan runs very stably, and they see nothing except the fan blades that circulate rapidly.

The faint burnt smell came from the air, which made them know that a few more insects were sucked in by the fan.

The rust, dust and even spider silk on the barbed wire mesh all dispelled their insignificant suspicion, and the patrol team returned to the normal patrol route and completely threw this little thing behind their minds.

Behind the fan, Li Yao wiped away the cold sweat from his forehead and grinned.

The infiltration from the fourth warning area to the third warning area has been half successful!

In front of him were black ventilation ducts that went straight to the ground, covered with various deadly poisonous insects, acting as a warning system.
