In the year 2200 of the old calendar, there were frequent natural disasters around the world. Various apocalyptic schools have grown, and countries around the world have introduced policies to resettle refugees, but they have not noticed that the cornerstone of this world is quietly changing.

Some substances began to simulate objective rules to produce self-consciousness, while some abstract rules, which are ties and constraints, began to materialize and materialize. Many new creatures and materials appeared in front of humanity, as if they had spied on new treasures, and for these new resources, the world began to descend into strife and war.

In the year 2356 of the old calendar, the first "living gold" appeared. The inside of the metal body mimics the nervous tissue system of living organisms. The "living metal", which is regarded as a miracle, has drawn the already tense nations into endless wars, and until the first cataclysm, humanity has been constantly fighting with each other.

In the year 2499 of the old calendar, the first cataclysm, the "metal frenzy" broke out. With the source of the South Pole, it seems that endless metal life has swept across all continents. And along with natural disasters, there are also man-made disasters. The Order of Doom suddenly rose up and used North America as a base to promote apocalyptic rhetoric. The tower of human civilization collapsed. On the ruins of blood, fire and bones, the old calendar ends and the new one begins.

The first cataclysm, the Metal Rush, devastated continents in just three months. Africa and South America, near Antarctica, bore the brunt of the losses. Just when the rest of humanity felt that death was imminent and that there was nowhere to escape, most of the metal life began to converge and return to Antarctica, where they disappeared en masse.

In the 57th year of the new calendar, the second cataclysm "Elemental Storm" appeared, and the whole of Oceania was engulfed, and the elemental spirits appeared on the stage of history for the first time. In the same year, the Doomsday Sect held a "sacrificial mass" ceremony on the American continent, and the northern and southern continents were gradually deserted, and the previous frenzy erosion was no longer suitable for habitation. The surviving populations migrated to former Asia, now the Middle Continent.

In the year 359 of the new calendar, the elemental storm that had been burning for 300 years suddenly went out, and a large amount of abundant energy ejected from the "sea eye" spread out to the world. Humanity, which is struggling with the drastic changes in the environment and the calamity, has finally taken the step forward in evolution. "Aura", "Ability", "Magic"... Humans are like newly awakened young beasts, happily groping for their newfound talents. However, children are susceptible to self-injury. A new system of power has suddenly been added to the already broken order, and countless human beings who have been carried away by this new power are greedily grabbing everything they want.

In the year 362 of the new calendar, the third man-made disaster, the "super cholera" broke out around the world.

It wasn't until the year 370 that the madness finally ceased completely. The reconstructed social system of human civilization has finally ushered in a real respite, and the global population is no longer one in the past than in the glory days of the past. The remaining countries and federations in the Middle Continent have set up security borders to provide shelter for the surviving human beings who survived the "exploration period" of 370 years before the new era.

Today, it is the year 534 of the new calendar. Even though the outside world is still full of weirdness and unknowns, at least there is enough combat power to defend every city of Anjie, and ordinary humans who have not awakened their abilities can survive.

"Individual power can destroy the city and shake the mountain, and everyone can be fed and clothed, and children as big as you no longer need to face life and death every day, which is the greatest achievement of the ancestors' hard work in the past hundred years. There were once people who forged ahead in the midst of calamity and spoke out in the midst of the mob, just so that the flame of human civilization could continue to be inherited. We cannot record the names of every martyr, but we must remember that today's stability was achieved by their blood and tears. Towards the end, the voice of the tour guide became more solemn and solemn.

"There were ancestors who paved the way, and now there are you moving forward, and there will be inheritance in the future. All the old things are returned to Tibet and started in the present. Let you know what the old times were, who did what we are now, how the world has changed... This is the meaning of the existence of the Gui Collection. ”

Outside the museum, the sun is shining, the autumn breeze is gradually rising, but the slightest coldness cannot cool the boiling hearts of the teenagers here.

Squinting his eyes at the sun hanging above his head, Mo De finally understood the meaning of the man's words. Even after listening to the man's own talk and reading it cursory from history textbooks, this trip to the collection still made his mood far more than his peers.

The vast, tragic, and tragic past came to me from the yellowed pages and galloped away. All that was left was shock.

......

It wasn't until after lunch that the silence of the crowd faded away. The head teacher, Lao Qiao, brought new news to the current group of children who are still immersed in the atmosphere of the "Returning to the Collection".

"Let me check again, has anyone decided to temporarily withdraw from the autumn hunting event?" Under the thick lenses, Qiao Yuanshan glanced at the group of children who still had some serious expressions. "Okay, make sure no personnel are exiting."

"Free in the afternoon, rest well in the evening, gather at six o'clock tomorrow morning, and set off for the autumn hunting preparation base." Old Qiao looked at the group of sixteen or seventeen-year-old teenagers in front of him, and after watching their faces gradually regain their vitality, showing a happy smile that belonged to their age, the corners of his mouth couldn't help but hook up a smile.

"However," he deliberately paused his words, and only after everyone's eyes looked at him did Lao Qiao continue: "After a while, I and the other head teachers will set off in advance and go to the Autumn Hunting Base to make some preparations. From today, everyone in Class 20 will obey the arrangement of the class leader. After speaking, he handed Su Ziwen a booklet.

"All of you are coming of age, and you have to learn to take responsibility and responsibility. I believe that the trip to the collection has made you change a little, but the next autumn hunting activities, there will be no teacher to follow the whole process. You need to learn to act independently and self-judgement, and always remember that teamwork is the quickest way to solve problems. ”

"Ziwen, in the booklet is tomorrow's schedule and various precautions for autumn hunting activities. You can choose another person to lead the team with you. ”

"Okay, Mr. Joe. I recommend Mo De to lead the team with me. Su Ziwen lifted his glasses and said in a natural tone.

"Good. Su Ziwen, the leader of the autumn hunting activity of the 20th class of Tianshui High School, and Mo De, the deputy, have a total of 41 members. He didn't raise his eyes to ask for Mo De's opinion at all, Lao Qiao directly cut through the mess and filled in the confirmation form in his hand to determine the number of attendees, and then left without looking back.

"I'll come back to pick you up after the autumn hunt, and when the time comes, I'll come back intact and a lot of jumps, I understand if there is ?!。"

"Got it!!" "What the hell ???" The roar of everyone erupted in unison completely covered out Mo De's wail.

Turning his head to look, he saw Mo De standing in the carnival crowd with a confused expression, Su Ziwen picked up the booklet and covered the corners of his lips, but a slight sly smile leaked between his eyebrows.

"Su Ziwen, you calculate my !!" The impotent fury wrapped in the wave of high-fives and celebrations naturally can't make any waves.
