"Powertrain Outer Armor?!" Liu Fei's body was shocked, on the Star Yao and Stan, Liu Fei has a certain understanding of the power system, simply put, the power system is the engine, if the main control optical brain is the brain of a spaceship, then, the engine is the heart of a spaceship, it not only provides power for the spaceship, it also provides energy for the entire spaceship.

If the main engine of the space city is destroyed, it will definitely be a disaster, the backup energy source will not be able to maintain the huge life cycle system at all, nor can it maintain the gravity system for a long time, people will be in a state of weightlessness, of course, the most deadly thing is that when the energy supply is lost, the warm space city will soon drop to minus 200 °, and all the residents will freeze to death......

Relatively speaking, most of the main control optical brains are in the core of the spaceship, and it is difficult to be hit by external forces, and the position of the engine is much more dangerous, because most of the engines have tail flame vents, although the tail flame will use some advanced cooling technology, but because the tail flame part cannot be moved, this part is the most vulnerable to attack......

Of course, it is not easy to attack the engine part of a space battleship, after all, the speed of a space battleship is very fast in wartime, but this is fatal to Kodo Space City, because Space City does not have the agility of a space battleship to change direction.

"Liu Fei, the pirates have divided most of the warships to attack the engine compartment of the Space City, according to this attack speed, the roundabout composite armor of the engine compartment can last for a maximum of twelve hours, and you must repair at least one battleship passage in these twelve hours......"

"The armor in the engine bay can't be repaired?" Liu Fei felt the imminent crisis in the serious voice of the small strong light.

"The engines in the Space City are too large, and besides, the engines are running, and now the DC tail flame vent has been turned off and the roundabout composite armor protection device has been activated, but because of the high temperature caused by the operation of the engine, the engineers cannot repair it at all unless the engine is turned off......"

“……”

Liu Fei was speechless for a moment, turning off the main engine at this time would be tantamount to suicide, because most of the energy shields were powered by the main engine.

"Liu Fei, because the pirate's battleship is attacking the engine room, the main engine has started the protective device of the roundabout armor, this armor has a total of twenty-four layers of protective armor, because there is an energy shield, it will take at least half an hour for the pirate to destroy a layer of armor, that is to say, if the battleship passage of the space city is still unable to open within these twelve hours, at that time, the entire space city will turn into a sea of fire......"

"Twelve hours!"

"Yes, twelve hours, you have to find a way, either leave the space city in these twelve hours, or help the space city through this difficulty, there is no third choice!"

"Let's run!" Liu Fei was used to staying away from danger, so he made a decision subconsciously.

"Escape...... Where did we flee? Xiao Qiangguang said in a mournful voice.

"Let's get to work." Powell saw that Liu Fei had been in a daze, and couldn't help but remind.

"Space City is going to be destroyed." Liu Fei shook his head.

"Hehe, no, I have lived in the space city for seven years, I know very well the strength of the space city, if it is the fleet of the seven star fields to destroy the space city, I still believe that if a group of rabble pirates can destroy the space city with a history of hundreds of years, it is simply impossible, soon, the 'poisonous bee' battleship of the space city will come out of the nest, and when the time comes, the pirate gate will scatter ...... birds and beasts" Powell said disapprerovantly.

"What if pirates attack the engine bay?" Seeing Powell's confident expression, Liu Fei couldn't help but ask rhetorically.

"According to my understanding of the space city, the designers of the space city took into account the crisis that the space city may face, the protection of the engine compartment is the top priority, the use of the most advanced roundabout composite armor, a total of twenty-four layers of composite armor, if you open the energy shield, with the pirate fire system, to completely destroy the twenty-four layers of armor, it will take at least twelve hours, with the war potential of the space city, in these twelve hours, at least one passage can be opened, unless ......"

"Unless what?" Liu Fei didn't like this way of speaking at a critical time, and asked with a frown.

"Unless, there is a mole in the space city that leaks all the external passages of the space city, if the pirates get the holographic map of all the passages, they can use the hot wire cannon to melt the metal passages and prevent the 'poisonous bee' battleship from flying out of the space city...... Not good...... There really are moles! Powell's color changed, he thought of a fact, according to the usual practice, there will be poisonous bee-class space warships cruising around the space city for a long time, and a radius of millions of kilometers will be included in the monitoring, it is impossible for the pirate ship to approach quietly, and it is impossible for the space city to have no power to fight back.

Powell naturally did not expect that the second person in the space city had already leaked all the secrets of the space city in order to seize power.

"Liu Fei, he is familiar with Space City, maybe there is a way, tell him that Peter, the number two person in Space City, betrayed the City Lord of Joey." Xiao Qiangguang's brain appeared in Liu Fei's mind.

"Yes, Peter of Space City betrayed Lord Joey." Liu Fei repeated.

"Ah...... Peter betrayed Joey, they were two brothers...... No! I can't die, I can't die......" suddenly. Powell's eyes lit up: "There is a way, let's speed up......"

Powell then shook his head again with a look of frustration.

"Speed up what?"

"The solution is very simple, improve the efficiency of the space city, but ...... It's impossible...... Look at them...... They are all residents of Space City for a long time, and they have a blind confidence in the strength of Space City......" Powell sighed.

Liu Fei followed Powell's gaze, and suddenly froze, the rush was just an illusion, many people even gathered together to chat, and the mustache was sitting on the loader smoking a cigarette, looking leisurely, there was still a rush to burn, and some waiting transport trucks were gathered together like headless flies and bumped into each other, without the slightest tension of war.

"If I make them more efficient, do you have a way?" Liu Fei asked.

"Yes, I can provide them with metal formulas, and I can also increase the resistance of their armor to blows by thirty percent!"

Powell replied categorically, with a hint of pride on his face, a sparkle of wisdom in his blue eyes, and his sloppy body seemed to suddenly become taller.

"Good!"

Liu Fei bent down and pulled out Yuehua tied to his calf, and the moment he pulled out the scabbard, Yuehua let out a pleasant humming sound, and Liu Fei's keen six senses seemed to feel the pleasure emanating from the plastic memory metal.

"What are you doing?"

Powell couldn't help but give a cold shudder, and this young man who looked thin and ordinary suddenly exuded a fierce cold aura, which was thrilling......
