In the oval conference hall of Nuoda, it seemed that every participant was rejoicing in Lu Yang's invention and creation, but one person remained silent, only sat motionless, and could not see what he was thinking on his expressionless old face.

That man was Professor Nivanch.

When the noise that resounded through the ceiling had almost subsided, Nivanch finally patted the table in front of him. There were sound transmission holes on the table, and the sound of slapping overtook the voices, so the hall was quieter.

Lu Yang was a little disappointed that he didn't get praise from Nivanchi, but he still asked respectfully: "Old professor, when this invention was still in the gestation stage, I discussed its practicality with you, and at that time, you were very interested in neutralizing toxic particles with plant carbon gas, and strongly recommended that I continue to study, but why is it so cold now?" ”

Nivanchi sighed sadly, nodded, and said, "Yes, at that time we did decide that the filter could be used as the first barrier against the enemy. If the enemy's level matches what we think they are, they won't even be able to pass the first level. However, time has passed, and the only thing I can tell you today is that extracting the sap from activated charcoal-cultured plants and vaporizing the sap into a white mist resistance can only be effective against common pathogenic viruses, including air pollution particles. If it's normal, it's a good way to purify the air. But ......"

At this point, the professor paused, and everyone looked at him with bated breath, their eyes full of worry.

Mengqi was also curious, he wondered if the professor would choose to tell the truth about the negative emotion virus at this moment: emotional particles come from the light of nothingness, which cannot be removed with industrial cleaners.

Nivanch mustered up the courage to continue: "However, for the unknown particles created by alien creatures outside the King Continent, the wisdom city has not been able to find any cleaning agent that can fight against it, so I can only tell you very sorry, Professor Lu Yang, your invention can only be used as an ordinary radar in the face of alien viruses." ”

"Ah~"

"Shiro is happy~"

"How can this be~"

......

The noise in the conference hall rose again, and compared to the cheers just now, mixed with sighs of disappointment, the atmosphere suddenly became more and more desolate.

After listening to Nivanqi's evaluation, Lu Yang, who was originally high-spirited, felt very uncomfortable, but he couldn't find any rebuttal arguments, so he could only put away the test equipment and retreat to his seat alone to sulk.

"Hmph, the professor still can't make up his mind after all, and tells the ordinary people in advance how bad the actual situation is. Isn't such a cowardly approach causing trouble for yourself? Mengqi thought indifferently.

Next, eight other scientists took turns to play, each of whom used what he thought was the best at dealing with unidentified particles, and one even had the idea of digging out an ocean in a large open space in the south of the smart city, and the water of the ocean was filled with particulate solvent and flowed underground. When an alien invasion occurs, seawater is used to absorb particles on a large scale and send them underground to prevent harm to people on the ground.

This is the most attractive of the eight ideas, the highest call to win the championship, but the final judgment is still in the hands of Professor Nivanch, when countless pairs of expectant eyes are on him, he only calmly said one sentence, everyone's fiery hearts are like falling into the sea, completely cold.

"The idea of using seawater to suck up unidentified particles is great, but the problem is that you can never know the direction in which the particles move, and no matter which method you use, they spread in all directions," the professor said. ”

Of the ten applicants, nine have been "killed", and in the end, only Nivanch himself remains.

The spectators who watched the test competition came one by one, and they really did not want to go home disappointed, and this failure also meant the destruction of the future. Such consequences are chilling to think about, and they have to pin their hopes on the gray-haired old professor.

Under the gaze of hundreds of pairs of eyes full of sadness but still mixed with expectation, Nivanch slowly got up. He stood in front of the chair tiredly, and people had the illusion that he was not sitting just now, but had done extremely heavy physical work, so he was so tired that he could not support it now.

"Professor Nivenki, are you alright? If you don't mind, we can take a break for everyone to go and put some water or enjoy some tea and snacks. The chairman-in-office, Yorkefu, said with concern, but seemed to be unaware of his confused words, which made the audience frown.

The Authority's higher-ups, with the exception of Yorkev himself, were all elegant people, and foul language such as "release water" was taboo for them, let alone on a par with drinking tea.

Nivanch didn't want to rest, he couldn't wait to introduce the Demon King to the attendees in a minute, and inform the defense center to immediately close the entrance to the smart city and change the entire defense system in case the enemy released any monsters to wreak havoc.

However, the meeting had been held for such a long time, and it was necessary for everyone to relax, so he had to nod and agree.

Yorkef announced a temporary adjournment of the meeting, and the solemn atmosphere dispersed as soon as it was "uproar", and many people began to get up and walk out. The demons who came with their master stood against the wall, and when they saw that their master was going out, they rushed forward to serve.

Mengqi also lost no time in running towards Nivanqi, the demon king did not dare to stay alone, so he hurriedly followed, and the two quietly came to the professor's side.

Nivanch reclined in his chair, seemingly deep in thought, unaware of the crowd around him.

Mengqi was about to speak, when a voice came from behind Leng Buding: "Professor Nivanqi, the work you used to participate in the competition is this stupid cow that almost squeezed and injured people in the elevator, right?" ”

"Huh?" Nivanqi was surprised, and Mengqi was also surprised. The person who spoke was Yorkeff, and everyone could hear it as soon as he spoke, but at this time his words were full of provocation, and he didn't know where to throw his sleepy fatigue.

"Chairman Yorke, why did you come to me at this time? What I bring will be revealed in a moment, and now you can't let me, an old man, rest for a while? Nivanch looked up at him and said.

Mengqi and the Demon King carefully stepped aside, and York's kind face changed, and he stood condescendingly in front of the professor and sneered: "I don't know how you discovered the secret of the Demon King, but it is impossible to close the Wisdom City, otherwise we will be completely isolated by the King Continent, and I am afraid that there will be more enemies than unknown particles at that time." ”

Nivanch was taken aback, but quickly calmed down, pushed the reading glasses on the bridge of his nose, stared at Yorkev scrutinically, and said, "Your Excellency, you can't really be the enemy spy I suspect, right?" ”

Yorkoff shook his head and denied: "No, no, no, I'm certainly not a spy. For the prosperity of the smart city, even if I have to dedicate my life. But I now understand where those unknown particles came from, it was you, Professor Nivanchi, who introduced the enemy to the Wisdom City, and my secretary Xianglu has investigated that you are the culprit of all this crisis! ”
