The spacecraft hovered on the roof of the destroyed exhibition hall and did not fully land, maintaining a high degree of maneuverability. The hatch of the spaceship opened, and three men dressed in strangely styled full-coverage armor jumped down and landed steadily, although the heavy armor made it impossible to see the appearance, but from the shape of the body it was two men and one woman.

A bold teenager in the trapped crowd secretly took out his mobile phone and took pictures that were enough to cause a public sensation.

This alien spacecraft attack on the world's most famous scientific research organization will definitely shock the world, unlike the previous attacks where the damage was only limited, the damage caused this time is at the level of endangering the basic strength of the alliance, once the headquarters of Albert Laboratory, which has gone through hundreds of years of history, is completely wiped off the map, the loss of many top scientists will affect the scientific and technological development process of the entire human race.

What the public doesn't know is that the people who came out of the spaceship were not the alien invaders they thought they had, but three humans, because the only alien on this planet has turned into a specimen lying in the research institute of the hellfire base.

"We acted as planned."

Felix and Nix nodded, and although they didn't like Mutosuke's person, obeying the commander on the battlefield was an unquestionable rule for Hellfire.

"Start searching for the target's electromagnetic signal."

The electromagnetic wave characteristics of the space crystal are too easy to identify, Felix quickly found the location of the crystal experimental device, the security of the laboratory is no better than that of professional soldiers in a military base, and in the face of such a situation, almost no one organizes decent resistance, so that Felix and the Knicks can go all the way unimpeded.

"It's here", Felix looked at the spherical node on the huge ring detector in front of him, the spherical node was closed, and the detector was still in operation.

Felix was not sure if the machine would cause an explosion if it was forcibly blasted, so he simply raised his arm, and an energy cannon shot out of his armor arm destroyed the electric switch, and the power supply circuit of the detector was broken, and the machine immediately stopped running.

Felix concentrated the armor energy on one of the helmet's mechanical eyes, which shot a tiny laser, carefully cutting the spherical nodes layer by layer, and he had to avoid bombarding the space crystal directly with the laser.

......

Crescent Moon and Ning Fei had noticed that there were a number of civilians trapped in the exhibition hall, but there was no sign of the intruder in the exhibition hall except for the spaceship suspended at low altitude.

"Captain, call Captain", fortunately, the mechanical skeleton has a built-in communicator, and Ning Fei is connected to Captain Kevin.

"Ning Fei, we are on our way back, how is the situation now?"

"The spaceship attacked Albert, at least three people have been observed so far, these outer space invaders are very advanced in weapons and equipment, their goal is supposed to be to come and take the space crystals, and now the situation here is terrible, there are many civilians trapped, and the casualties in the ruins cannot be counted for the time being."

Kevin's face was solemn, there was still some time before his destination, but for the firepower of that spaceship, if he wanted to, he could raze the entire laboratory to the ground in an instant. And Ning Fei and Crescent have limited manpower, on the one hand, there is an emergency rescue work, otherwise more civilians will be killed in the attack, on the other hand, it is likely that they will not be able to stop the spaceship from taking away the crystals, once the alliance loses the crystals, then even the only chance to catch up with the technological strength of the alien invaders will flow away from their hands, and humanity will face a greater crisis of destruction in the future!

There wasn't time for Kevin to think too long.

"Rescue civilians!"

"Are you sure?" , This is tantamount to giving up the space crystal, when Ning Fei heard Kevin's command decision, he was surprised because he understood the value of the crystal better during Albert's time, but he was not very surprised.

"It's all up to you, hold on!" Kevin's voice is firm, more of a trust in his companion.

"I'll do my best."

Ning Fei made a gesture to the new moon, and the two began to act separately, Ning Fei went to rescue the trapped people, and the new moon was responsible for evacuation, in order not to let the spaceship above notice, and attack again, the two tried not to make too much movement.

One of the walls of the pavilion has collapsed in the bombardment, although the main structure is still partially retained, but the scattered masonry and concrete have blocked the exit, and there are about a dozen people trapped inside, looking at the clothes that should be middle school students, and a leading middle-aged male teacher, gathered in the corner.

The middle-aged male teacher was trying to remove the debris blocking the exit, but the concrete blocks that had no choice but to fall were too big, and there were exposed twisted and crossed steel bars, which ordinary people could not move.

"Hey, the people inside, I'm here to help you, listen to me", Ning Fei whispered to the trapped people outside the collapsed pavilion: "Let me come, all stand back, be careful of falling rocks!" ”

The middle-aged male teacher and his students hurriedly stepped back.

After adjusting the output power of the mechanical skeleton, Ning Fei grabbed the steel bar on the concrete block and pulled it outward, and the concrete block weighing hundreds of catties began to be moved, the dilapidated wall "clicked", more gravel and dust fell down, and the cracks became bigger and bigger.

Suddenly, there was a "click" sound, and the entire wall above fell suddenly, pressing the concrete block, and the huge gravity came down, Ning Fei almost couldn't support this force, fortunately, the body subconsciously leaned forward quickly, and used one shoulder to hold the concrete block to death, and the heavy concrete block was connected to the falling wall above, and it fell more than 20 centimeters, before Ning Fei was half-bent over.

The situation became dangerous in an instant!

If it weren't for the fact that the mechanical bone armor on Ning Fei's body had been relatively completed, even if the strength was enough to support it at this time, I am afraid that his shoulders would be pressed into a blur of flesh and blood.

The concrete blocks could no longer be moved, otherwise the walls would fall down several meters high and bury everyone in the rubble.

"Hmm...... Come on...... Try this thing, it's my favorite tool! Ning Fei said with difficulty.

Saying that, Ning Fei switched the mechanical glove to the fingertip form, and the fingertip of the index finger of the left glove rotated to reveal a tiny laser emitting hole, aimed at the steel bars on the concrete, and the hot fine laser beam sprayed out, melting the steel bars and cutting them into a smooth section, and the steel bars that were cut off fell down with a "clang".

It worked!

Ning Fei was overjoyed, and continued to cut, cutting out a channel from the twisted and staggered steel bars, just enough for a person to climb out.

"Quick! Come out quickly, I can't hold it for long", Ning Fei shouted to the people inside.

"One by one."

"Hey...... Little fat man, you have to lose more weight and work hard......"

The middle-aged male teacher was the last to crawl out, looked at Ning Fei gratefully, and said, "Thank you for saving us, I am a teacher from Ayton Middle School, they are my students, how can I help you?" ”

Ning Fei was still struggling against the wall, and it would collapse if he moved, so he said, "Help me find a support." ”

"Is this okay? Sorry, the stick is too short, I'll look for it again. ”

"Oh, forget it if you don't, take everyone out first", Ning Fei pointed to the sky, reminding that the spaceship was still above, don't attract its attention.

The middle-aged male teacher understood that staying where he was would only drag Ning Fei down, so he quietly retreated and evacuated with the students, and after retaining a safe enough distance, he stayed to pay attention to the situation on Ning Fei's side.

Although Ning Fei's transformed mechanical skeleton is more flexible and intelligent, it is not as sufficient in energy as the military mechanical skeleton, and the continuous high power output support force will sooner or later consume energy.

Ning Fei hooked the stick under his feet, compared it in his hand, it was indeed too short, and threw it aside, propped his hands on the concrete block, mobilized the output power of the mechanical skeleton to concentrate on his arms, lifted it up hard, and the wall moved up!

Ning Fei's shoulders no longer supported the concrete block, only the strength of his hands to resist, and the mechanical skeletal system had begun to alarm, and the output power exceeded the load.

Overload operation will damage the components, and in addition, Ning Fei also found another problem with this set of devices, the mechanical skeleton in the process of use, the stress is often concentrated on the connector, although the material of the connector is a metal material that has been worked hardened, it still has an elastic limit, once the external force exceeds this limit, irreversible plastic deformation will occur, resulting in the entire part can not be used normally.

In the case of the feedback of the mechanical skeletal system, the limit design of the arm connector material, in the face of the current situation, its limit value is too small, and then a certain degree of upward force, the connector may be deformed or even broken, and the arm parts can no longer be used normally.

In the face of this internal and external troubles, Ning Fei no longer hesitated, no longer continued to exert force upward, but changed the direction to push the concrete block into the exhibition hall, his body quickly tilted, and with the help of the reverse thrust, he quickly retreated.

At this time, the dilapidated and cracked wall completely lost its support and fell down directly, and Ning Fei quickly rolled and dodged.

The middle-aged male teacher and students also breathed a sigh of relief for Ning Fei when they saw this scene.
