Countdown, 25 seconds!
The Xiaolong took photos of all angles of the military restricted area, including the fixed patrol routes of the two patrol teams, and sent them to Li Yao's mind for modeling.
Li Yao's main consideration was what to do if the patrol team changed its patrol route midway?
Jin Xinyue said that in the standard warning drill of the Ten Thousand Demons Alliance, each patrol team will set up three to four different patrol routes, which will change every half an hour or an hour.
If Li Yao and the Fire Ant King had more time to observe, they could see the pattern of changing patrol routes.
But they only had a few minutes to prepare and had to try their luck.
Once the opponent really changes course, Li Yao must be prepared.
Based on the terrain in the military restricted area, he calculated in advance twenty-three changes that the patrol might make, and determined that he only had 7 seconds at the minimum.
Countdown, 15 seconds!
The Fire Ant King took out a very delicate cylinder engraved with demonic patterns from his arms.
He gently unscrewed it and flew out from the cylinder two black beetles with a green vertical stripe growing on their backs.
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 to the entrance of the No. 2 ventilation duct in advance.
Countdown, 5 seconds!
Li Yao took off his disguise as a secret treasure merchant and put on a new leather suit.
This suit is so thin that it clings to the body like a second layer of skin, with almost no gaps, and the direction of every muscle is highlighted.
"Uh-huh!"
Li Yao lightly touched a rune on the waist of the suit, and ripples appeared on the surface of the light gray suit, gradually becoming translucent, and finally seemed to melt into the air.
Make him completely invisible!
This is a cellular invisibility cloak prepared by experts from the Blade of Chaos organization by extracting cells from chameleons, silver fish, bamboo insects and other monsters with color-changing, mimicking and transparent powers.
When it is still, it is extremely difficult to detect, like an ice cube thrown into water.
The only flaw is the ingredients that make up the cellular cloaking suit.
They are all highly active and need to be stored in a special culture medium.
Once taken out, their lifespan will not exceed five minutes when exposed to the air.
Basically, after four and a half minutes, the cloak wears off.
On the other hand, this invisibility cloak only works best when stationary, and when moving at high speeds.
There will still be afterimages left behind, making the air appear strangely distorted.
Countdown, 0 seconds!
Li Yao floated out like a wisp of smoke.
"Uh-huh!"
He keenly sensed the thermal energy ray net on the high wall of the military restricted area, but he contracted the bones and muscles around his body to the limit, not much bigger than a cat, and got through the gap in the thermal energy net!
The two patrol teams were heading in the opposite direction of the No. 2 ventilation duct, and Li Yao was counting the time it would take for them to turn back.
While observing the scanning angles of several biochemical monitoring eyes high up, they moved around in the blind spots as large as the tip of a needle.
Move quickly towards the target.
Just then—— One of the patrols turned back early and changed a new patrol route before reaching the end of the military restricted zone!
"Damn it!"
Sure enough, it’s 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.
Without releasing any heat or breath, he watched helplessly as this patrol came towards him.
As long as you stay absolutely still, the invisibility cloak will work.
The invisibility time is five minutes, which is enough!
The patrol team passed by Li Yao.
The nearest soldier could touch Li Yao's head just by stretching.
Fortunately, they didn't notice a slight distortion in the air very close to them.
Even half a minute after they walked over, Li Yao remained motionless, relying on the Xiaolong to observe their new patrol route.
After switching to the second set of patrol routes, the blind spots between the two patrols were completely different from before, and everything had to be recalculated.

After silently calculating for one minute and two seconds, Li Yao started it again!
Deep in his brain, the biochemical monitoring eye above his head, and the two patrol teams' combined twenty or thirty eyes, seemed to emit a series of substantive red rays, forming a criss-crossing line of death in front of him. .
The dead line kept changing, and he danced along with it, sometimes fast and sometimes slow, sometimes advancing and sometimes retreating.
It took him more than three minutes to move with difficulty to the entrance of the No. 2 ventilation duct.
At this moment, there is only the last minute left before the invisibility cloak expires.
In order to transport air to the main underground part of the huge Blood Demon Eye, each ventilation duct is about one foot in diameter, and a medium-sized adult can barely squeeze in.
But the entrance to the ventilation duct is covered with an extremely fine barbed wire mesh, and there are warning arrays around it to prevent cutting.
Li Yao took a quick glance and figured out the working principle of the warning talisman array.
It should sound an alarm by sensing vibrations.
Once an external force breaks through the barbed wire fence, there will definitely be abnormal vibrations.
As long as it is sensed, an alarm will sound.
"Swish, swish, swish!"
Inside the barbed wire, half a meter deep into the pipe, three huge fan blades were rotating rapidly at a speed of 1,500 revolutions per minute.
The fan blades were also engraved with offensive wind talisman formations, rolling up an unstoppable force of wind.
The blade turned this section of pipe into an invisible meat grinder.
There are still 45 seconds left before the invisibility cloak completely expires.
"Zizzi, zizi!"
Li Yao sensed that the invisibility cloak gradually felt stiff and sluggish.
This is a sign that the invisible cells are about to wither.
At this moment, the two patrol teams all walked to the farthest place from him, and all the biochemical monitoring eyes happened to be scanning other areas.
However, after this route adjustment, the time left for Li Yao was only 11 seconds!
"Enough!"
Li Yao's hands instantly turned into two clouds of gray mist, and he first gently attached four magnet-like magic weapons to the side of the warning talisman array.
The four magic weapons formed a temporary circuit, which was equivalent to temporarily introducing the warning talisman array into a " "Fork", allowing it to ignore the subtle vibrations on the barbed wire.
Immediately afterwards, Li Yao used an extremely sharp bone blade to carefully scrape off a large amount of rust from the barbed wire and put it away.
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 got in!
It is not difficult to break through the barbed wire fence, but the difficult thing is to restore it to its original state!
The patrol team at the farthest end of the military restricted area began to turn around, and the two biochemical monitoring eyes gradually turned their perspective back, and were about to lock on the entrance to the No. 2 ventilation duct.
Li Yao's ten fingers were like ten little boneless snakes, with a thin needle like cow hair sandwiched between the two fingers.
These thin needles are hollow, and there is a small liquid sac behind them, which stores trace amounts of natural viscose.
They were originally used to fix the components of ultra-micro magic weapons.
Li Yao manipulated the tiny muscles on his fingers, squeezed out the glue with a fine needle, and glued the short ends of the barbed wire together again.
He deliberately spilled some glue on the bonded edges, and then scraped off the glue that had just been scraped off.
The rust blew up.
Finally, he took out a can of spray and sprayed it lightly on the wire fence.
Suddenly, a layer of fine dust appeared on the surface of the "rusty" wire mesh, and there were even strands of broken wires that looked like the remains of spider webs.
At first glance, it looked seamless, with no trace of it being forcibly broken.
Li Yao then used his spiritual power to hook four "magnets" through the holes in the barbed wire, restoring the warning array to its normal circuit.
"Uh-huh!"
The biochemical monitoring eye scanned the entrance of the No. 2 ventilation duct and found nothing unusual.
But the lifespan of the invisibility cloak on Li Yao had also reached its limit, and distorted spots of light began to appear.
Once the patrol gets closer, they will definitely be able to spot the vague gray shadow behind the barbed wire.
The two black beetles of the Fire Ant King followed Li Yao in and crashed into the high-speed rotating fan!
This fan has fast rotation speed and strong suction, and it often sucks in some small flying insects.

These two black beetles were the "green oil fire bugs" carefully prepared by the Fire Ant King.
They hit the fan blade hard, and immediately made two "" sounds, and exploded into two small fireballs!
These two fireballs interfered with the wind talisman array on the fan blades.
The fan's self-protection mechanism started, and the speed dropped briefly, and it began to remove small foreign objects.
Li Yao took this opportunity to widen his eyes and his pupils kept trembling.
He could clearly see every detail of the rotation of the fan, and also sensed the wind blades that were invisible to the naked eye.
"Uh-huh!"
He successfully got through the gap in the fan blades that rotated at 780 rpm!
Three wind blades cut hard on his body, but the muscles all over his body were locked and no blood remained.
Half a second later, the fan speed returned to 1,500 rpm, and the patrol team just arrived at the entrance of the second equivalent pipe.
They were attracted by the sound of the green oil fire bugs exploding, and looked inside through the barbed wire fence with some suspicion.
The fan ran very steadily, and they saw nothing except the rapidly rotating fan blades.
The faint burning smell in the air told them that it was just a few more bugs that had been sucked in by the fan.
The rust, dust and even spider silk on the barbed wire all dispelled their trivial suspicions, and the patrol returned to its normal patrol route, completely forgetting this little incident.
Behind the fan, Li Yao wiped the cold sweat from his forehead and grinned.
The infiltration from the fourth security area to the third security area is already half successful!
In front of him was a dark ventilation duct that went straight into the ground, filled with all kinds of deadly poisonous insects, acting as a warning system. ... ...
