Mengqi stared curiously at the metal ball in the box, and when the professor said its name, he mumbled and stretched out his paws to touch it.

The professor stopped him and said, "If I were you, I would definitely not touch something that I have never seen in the past and don't know yet, otherwise I might die if I am not careful in the laboratory." ”

"Huh? Mourning...... Killed......? ”

The warning couldn't have been more severe, and Mengqi stuck out his tongue in fright, and his claws not only retracted, but also shrank behind his back as if they were burning.

Nivanch said: "The light wave encrypter, you can understand its working principle and purpose by listening to the name, which is to emit magnetic invisible light waves from the inside of the sphere to protect the electromagnetic communication frequency band from being stolen or invaded by third parties." The metal sphere appears to be complete and smooth, without a single gap, but at its core lies a seven-color spectral synthesizer that can penetrate anything. The scattered light is emitted through the molecular structure of the metal ball, and the bright crystal of the ball becomes easily suspended. But a layman who doesn't understand the principle will think that the light comes with the metal ball itself, so it loses to prevention. ”

This explanation is not difficult to understand, Mengqi understood it as soon as he heard it, but he couldn't figure out how the scattered light could kill people.

"And the way to use it, is to hang it from the ceiling?" He looked up, trying to find the orb slot on the ceiling surface.

Nivanch smiled hard and said, "Silly boy, electronic communication transmission is invisible, what are you doing hanging this metal ball on the ceiling?" ”

"This ......" Mengqi Mao's face was feverish, knowing that he had said something stupid again.

Nivanch stood up with the corner of the low cabinet and said: "Although I don't know the relationship between the unidentified particles and the celestial variable star, since I intercepted the unknown electromagnetic waves near the Authority and discovered that there were spies hidden inside, I have an extra eye and installed a small Cassegrain antenna for microwave communication on the roof of my laboratory. The antenna was never activated, and the enemy did not know about its existence. Now that the normal means of communication are no longer available, it is time to activate Cassegren. The antenna and this encrypted magnetic ball will definitely be foolproof, and no one will want to hack into my communication system again. ”

"Oh, it turns out that this metal ball is stuck in that kind of cauldron-like antenna." Mengqi had seen the antenna mentioned by the professor, and had always thought that it was just an ornament, and he always thought that such a beautiful house, why should he put such an ordinary ornament, but he didn't expect it to be very useful.

Nivanch shook his head again: "If the metal ball is stuck in the card slot and can't move, it's useless." It is installed using the principle of magnetic levitation, which can always reciprocate on the parabolic surface of the antenna suspended in the air to diverge and isolate the light waves. There was a hidden firing point on the antenna that fired metal balls that only I could find. ”

"Oh...... That's ......."

The amount of knowledge about antennas and metal balls was too great for Mengqi's brain to keep up, so he could only nod his head and dare not ask anything more, otherwise he would be too ignorant.

Nivanch helped Mengqi out of the command room and up a slender staircase to the roof.

The Cassegrain antenna is indeed not large, the inner diameter of the main reflector is only 1.5 meters, but the encrypted electromagnetic waves emitted are enough to cover the entire Infinity Egg Building.

Nivanch gasped slightly, and used one operation after another to activate the antenna program. Mengqi stood aside and tried to help, but there was nothing he could do anymore. But he noticed that from taking out the lightwave encryptor to installing it in the antenna device, the professor was wearing yellow rubber gloves on his hands during the whole process, which were anti-static gloves.

"Wow~"

With a pleasant sound, a small indicator light at the tail of the antenna lights up, turning from red to yellow and then from yellow to green, indicating that the antenna has begun to work. The light sound is the metal ball from the ball hole into the main reflective surface of the antenna due to friction with the electromagnetic waves, just when it is about to fall on the arc parabola, as if blown by a strong wind, suspended in a circle of rotation in the air, and the speed is getting faster and faster, so in the tail feed also along the edge of a circle of green lights, indicating that not only the antenna is working, but also encrypted successfully, the electromagnetic waves emitted by Cassegren can only be controlled by the operator in the Wuji egg building.

"Well, yes, the communication encryption technology obtained from the Ark really didn't disappoint me. How advanced was the science and technology of the origin earth, but where is it now? Or has it been wiped out in the depths of the universe? It's a fascinating mystery. ”

Nivanch sighed, looking into the distance with a fascination in the distance, although there was no vast universe in the distance, and there was no esoteric starry sky with twinkling stars.

Mengqi stared blankly at the professor, and although he couldn't guess what he was longing for, he knew that it must be the dream he had pursued all his life, and even before he died, it was extremely important. Unfortunately, he didn't have time to do it.

Back in the command room, Nivanch stood in the middle of the room and tapped his hand a few times, and the screen flashing black and white points of light immediately reacted, at first there were only some vague shadows, and soon the shadows became clear, becoming a busy human in a large office, and when someone noticed that the professor was trying to restore communication with them, the office immediately boiled.

"Commander Nivanchi!"

This is a name that surprised Mengqi, it seems that the humans in the Wisdom City have great respect for the old professor, and willingly let him sit in the highest position of administrator.

Nivanchi's pale cheeks flushed with excitement, of course, not because of the title of "commander", in fact, he didn't care about this title at all, he was excited that he could finally control the current situation in Wisdom City again, he needed to know how bad the current situation was.

"Dr. Lu Yang, it's great that we met again, and I hope you are as healthy as yesterday!"

Nivanch greets the person who appears on the main screen, the light curtain that covers the front wall. Mengqi knew him, the same doctor who demonstrated his filter radar to the attendees at the regular meeting.

This unusual greeting came from the Wuji Egg Building!

Lu Yang was talking to other colleagues, and his face was so anxious that he was obviously talking about a big deal. But when Nivanchi's voice rang in his ears, he immediately stopped talking and turned his head in disbelief, and it was at this moment that the crowd cheered, and he immediately understood what was going on.

"Great, Professor Nivanchi, we're all worried about you! It seems that not only is the Infinite Egg Tower safe, but you have also overcome the interference wave, and the communication between us is finally back to normal! ”

Nivanqi let the people cheer for a while before his face became solemn and asked, "Dr. Lu Yang, you are the person in charge of the overall distribution of weapons control points, so I don't know what happened in the city after not being in touch for such a long time?" ”
