"Your goal?" Na Yu shook the water in the cup with her cup, sat on her bed with Erlang's legs crossed gently, looked at Yan Yin, who was thinking about it, and continued: "In this way, I can cooperate with you, you must know that a month later is the day when the biological barrier will be replaced." ”

"What? How can we students not know about such a big thing? Yan Yin was startled and looked back at Nayu.

"I guess it's going to be said soon, I also knew about this when I checked their database, it's just a small surprise, and the things behind it are even more exciting" Na Yu took a sip of coffee and continued: "But it's a pity, those materials are confidential information of 'Dragon Island', I can't provide you with them, and it is estimated that no one has seen those materials except the principal." ”

"I'm not interested in those, but what happens when the biobarrier is gone? Exotic beast tide? Yan Yin touched his nose.

"Remember an old experiment? It's that shark and catfish experiment. Put both creatures in the same tank, but separated by a glass plate. ”

"I know that the shark gives up after dozens or even hundreds of attempts, and even if the glass plate is removed, the shark will not rush up and eat the catfish."

"So ......"

"I know what you're thinking, but isn't it a little naïve to be a hacker with an extremely high IQ?" There was a hint of sneer on the corner of Yan Yin's mouth. "It is true that the shark may be indifferent for a short time, but who said that there is only one shark, and who can say when the shark will be there? By whom? Thrown in? ”

"I'm stupid. But back to the question just now, who do you choose? Nayu took another sip of coffee.

"Anyone can be, originally I only had my eye on one person, but now, my plans have changed."

"Anyone is possible?! And Barlow? Nayu said with a smile.

"As a last resort, I have my choice." Yan Yin smiled, laughing inexplicably, laughing a little sadly.

"Sacrifice him?" Nayu asked very uninterestingly at this time.

"Sacrifice me!" Yan Yin said expressionlessly.

"Sacrifice...... I. Nayu muttered softly. Today is the last time we met in private, do you remember what 'Dragon Island' told us? Na Yu looked at the cup in her hand and said a little dumbfounded.

"Yes." Yan Yin paused.

"If you can't even fool yourself, how can you fool others?" The two of them read this sentence in their hearts. It's not a big deal, but it can make you sober up in the maze.

"Gone." Yan Yin got up and was about to walk out the door, but he suddenly stopped and whispered, "What is your real name and 'name'?" ”

Nayu thought for a moment and answered his last question seriously: "Finney Via, Darkflower Blade." ”

"Oh, then, farewell, Darkflower Blade."

"Farewell, waning moon ......"

After the two said goodbye, Yan Yin walked out of the door, and Fei Ni sent Yan Yin out of the door.

At this time, he is Yanyin, she is Nayu, it may be temporary, it may be forever.

As soon as Yan Yin stepped out of the door, the feeling of being monitored returned, and he looked tired, stuck the student in the door, and stumbled in.

The moon shone its meager light in the night sky.

It's still not full, and people are still watching.

It's really beautiful, it's a pity that no one can have it.

The boy had fallen asleep, and the girl was still staring blankly at the cup.

Time is beyond human control, and the next day is the next day in a blink of an eye.

Yan Yin washed up as usual, and then dressed up and went out, Barlow was waiting outside the door, and he smiled at Yan Yin, revealing a mouthful of big white teeth. So, the two went out together, had breakfast together, and then entered the classroom together.

"There is an important news notice at 10 o'clock, please sit in your seats in advance, today's teacher will explain the details of the important news in the afternoon, and you will be free to move around before 10 o'clock in the morning." The radio says so.

"I guess it's about the biological barrier." Barlow said mysteriously.

"What's the matter? What happened to the biobarrier? Yan Yin pretended to be at a loss.

"The biological barrier in the criminal city was the first to be built in addition to the main city, and after the biological barrier was replaced at home 8 years ago, we are definitely the next city to change the biological barrier." Barlow began to fiddle with what little knowledge he had.

"Then change it. What's more...... The White Devil 71 Catastrophe! ”

"Yes, the only variable that is well-prepared for humanity is the powerful mutant beast called the 'Undead Bird' in the A-class. The 'Immortal Bird' is different from the 'Immortal Bird' in the legend and mythology, its 'Immortal' is a powerful regeneration ability, and its other ability is 'Necromancy', which is said to directly kill the graduates of the Higher Military Academy. ”

"Like, I have the impression that the mecha killed it, the AI-controlled mecha, but at the same time it was scrapped." Yan Yin was silent.

"Therefore, people have given up the artificial control of mechas, the reason is very simple, one is that human beings are confined to such a small area, and there are only a very small amount of ore every year, although relying on this and that information, human beings have developed materials that can save ore, but relying on that machine, the price is that the less ore content, the lower the hardness."

"Half cannon fodder? Speaking of which, the city is actually made of that material, and white is its most striking feature. Yan Yin looked at the walls around him.

"Well, humans were very uncomfortable with this white color at first, but they either adapt or die, so they chose to adapt."

Barlow responded and changed the topic back: "The second reason is that isn't it a pity that a modern man with mutation ability sits in a mecha because of the ability given to him by God?" Unless the mech can match the mutant's abilities. ”

Yan Yin nodded in agreement.

"But, I've heard the unfortunate rumors of a war between the Duchy of Machine and the Freedom Alliance." Barlow's tone was relaxed, and he waved his hand helplessly, and continued: "Although there may be a fight in a few years or more than ten years."

"Heh, they're like two children in two houses a little far away, and outside the house are hungry wolves, and the two children are still talking on the phone and scolding each other, threatening to beat the opponent down, don't you think it's funny?"

"I'm afraid the wolf will break in." Barlow laughed, but stopped laughing as soon as he finished speaking.

The two looked at each other in horror and thought of something not so good.
