It's 4 a.m., the darkest time of the day.

It had been 27 minutes since the last wave of attacks, and the tunnel had only been excavated by Lin Yuan for 35 meters in the end, and then there was no way to continue.

The lack of oxygen is one thing, and on the other hand, the water starts to bubble up underground, and thanks to the fact that this is the upper layer of the hill, if it is in the plain area, it is impossible to say that more than half a meter of water will come out after digging about 10 meters.

For this reason, Lin Yuan and the others had to carry out the second plan, they planned to take advantage of the attack to attack again, capture a few experimental subjects alive, and then knock them out and take them out of the underground passage to test whether they could pass through the defensive shield.

"They're coming!!"

The Siberian tough guy is a genius with eagle eyes, and even at 4 o'clock in the morning when the night is at its heaviest, he can clearly see people's faces from a hundred meters away.

The blackened assailant piloted a small flying machine with a red light swaying from its tail that shot from a distance.

In order to ensure that the plan was foolproof, Lin Yuan crawled out of the hole in the ground, regardless of the embarrassment covered in mud, opened the dark long box placed on the ground, and took out the seventh-type juqiang of the Federation that had been assembled a long time ago.

"The self-aiming system has been activated!"

"Target dynamic simulation progress 0...... 100！ ”

"Air humidity: 40!"

"Wind speed: 60s!"

"Geomagnetic field strength: 06 Gauss!"

"Ballistic calibration: 1506ns!"

“……”

In the holographic eyepiece, a large amount of real-time data is like a waterfall, brushing down.

Lin Yuan opened his right eye, separated by two lenses, and when the data in the field of vision was determined, his fingers moved a few times like cramps.

Bang!

In the night sky, a ray of light pierced the darkness and accurately hit the control center of the small aircraft.

"Let's get moving!"

The first to arrive at the fall point was Zhou Weiwei, a smaller girl, with the help of the mayfly combat system, a distance of nearly 100 meters, swept by, and when she appeared again, she stood behind the attacker.

Burst!

Because he had heard Lin Yuan describe that the attacker's body structure was different from that of ordinary humans, before the battle plan was opened, Lin Yuan repeatedly told everyone that if they were not sure that they would be captured alive, they would be killed directly.

Therefore, Zhou Weiwei attacked extremely ruthlessly, the blade swept by, and the calf of the attacker who was nearly three meters tall flew directly and broke, and before it could roar in pain, the blade floated in front of him again.

Swish!

And so its arms were broken.

"Ahhh......h

The attacker who was cut into a stick fell to the ground heavily, and the spirit that had been inexplicably transformed was extremely strong, even if it was the pain of breaking hands and feet, it had already chosen to struggle and scream.

Zhou Weiwei ignored this waste, and swept her vision around, finding that Xie Wenle and Reginald had already beaten the remaining two, and her brows furrowed slightly.

"Why are there only three people?"

"Maybe the other party is rushing their own task? I can't tell the difference! ”

"Ahhh......h

The attacker, who refused to faint, had a contorted face and screamed as if he had been tortured by the Manchus, when in fact he was in a similar situation to the torture.

"Shut up!"

Zhou Weiwei was a little irritable, flew up and kicked directly at the other party's head, the latter subconsciously wanted to twist away, Zhou Weiwei snorted coldly, and the speed of the kick suddenly became a few points faster.

Bang!

The crisp sound of the head hitting the ground, well, a little muffled.

"Let's go, without further ado!"

"Hmm!"

The three of them carried the three unconscious assailants and quickly returned to the cave.

"A hole with a diameter of two meters is still too small!"

Lin Yuan packed up his weapons and looked at the three huge bodies dragged over by the three of them, and had a headache.

"Then cut some more!"

Zhou Weiwei opened the overclocking alloy knife with a blank face, just like those butchers who sell pork.

"Don't, let's do it first!"

Lin Yuan hurriedly stretched out his hand to stop it, this guy's mentality has changed a little since he shot to kill the enemy, it should be said that he has become more straightforward and decisive, and she is a little indifferent to the lives of outsiders.

Hopefully, it's not out of control!

Lin Yuan lifted the attacker in Zhou Weiwei's hand, and regardless of the other party's still bleeding wound, he lifted the other party's hat, and what greeted him was a distorted and pale face.

The skin on the face is very poor, I think it was soaked in water for a long time, and then one day it was suddenly scooped up, the skin of the face is loose, and the edges are transparent, like the lard that has condensed in those winter days, weird, and a little pitiful.

"The age is about 24-35 years old, the pupils change, the vertical pupils? Is it to be modified from snake creatures? It has 60 teeth, a very hard face, muscular cheeks, and a strong bite that can be judged to have a strong bite, a tall nose, and deep eyes, typical of European and American appearance......"

Lin Yuan once won the first place in the international health rescue competition, and he naturally had an understanding of the body structure of the human body, and roughly judged that the survival period of the other party would not exceed two hours, and Lin Yuan's heart was stable!

"I'll go down first, if it succeeds, Miss Han will go down second, then Zhou Weiwei, and then ......"

"I'm in charge of the Queen!" Xie Wenle leaned on the back of a stone, holding an alloy knife in both hands, like a martial arts swordsman, chic and natural.

Lin Yuan changed his opinion slightly, this guy almost tried his best to reason how to escape before he escaped the attack, and on this issue, he applied various psychological guesses, trace elimination, and anti-reconnaissance skills...... A basket of escape methods, skilled like a repeat offender who has escaped from prison countless times.

And now, he has changed back to the big guy he met for the first time, which makes Lin Yuan feel a little strange, but he won't think deeply.

After all, who doesn't have a story of a few catties of wine these days!

Lin Yuan carried the unconscious attacker and jumped into the deep pit, which soon disappeared.

In the narrow and dark underground passageway, the air is extremely thin, Lin Yuan controlled his breathing, carefully descended to 27 meters, and in the direction of the north, he dug a large hole 2 meters high horizontally, the soil structure here is extremely solid, surrounded by rock inlays, but he will not worry about collapse.

Walking more than ten meters along the aisle, Lin Yuan came to a light-colored halo.

Because he was worried about the killing ability of the defensive cover, Lin Yuan did not rush to dig out, so behind the halo, there was a thick wall.

"It's your turn!"

Lin Yuan took out a diluted XG Fen Ji from his bosom and injected it into the dying attacker, and when he was slightly conscious, Lin Yuan pushed it towards the halo with a wooden stick.

One meter!

50 cm!

30 cm!

10 cm!

In an almost breath-holding moment, Lin Yuan's hand exerted a slight force, and then the attacker suddenly rushed into the halo.

Zizi ......
