"Raw steel is a mineral extracted from the bones of mutated creatures, and it has strong plasticity when melted, just like steel before the apocalypse, and it is very hard after solidification, for example, C-grade raw steel is extracted from the bones of C-level mutant creatures, which can easily break the defense of C-level mutant creatures, and masters can use it to break through the defense of B-level mutant creatures. It was discovered in April of the last year of the calendar year, and the technology of extracting raw steel now represents the level of science in a city. I can extract 80 cubic centimeters of raw steel with a mutant creature of about 5 meters here, which is considered to be a better technology, and the best is Paul's in country M, and a mutant creature of about 5 meters, they can extract about 100 cubic centimeters of raw steel. Han Chao also knew that there was a fault in Liu Xin's basic knowledge, so he answered it for Liu Xin.

"The end calendar, what's that?"

"There's a big gap in your basics, let's go back first, I'll tell you from the beginning." Han Chao took Liu Xin back to his residence, poured a cup of tea for Liu Xin, and spoke slowly.

"The last calendar is the time after the end of the world, and from the first day of the end of the day the Common Era is overthrown and becomes a last calendar. The end of the calendar 0 year 1 1, that is, 2014 December 21 0 o'clock, that day the end of the day began to come, the end of the calendar is the end of the calendar, you don't think about the previous year of the Common Era, January 13, the zombies for the first time collective evolution. On January 17, the first human base, Base City of New York, was established. On February 10th, the first zombie siege was in Spring City, and then because of the addition of mutant creatures, the zombies were forced to retreat. On February 15th, the zombies evolved collectively for the second time and reached the E rank. On February 20, the energy supply was revealed from the Kyoto base, and human power was restored. On February 27th, the zombies evolved collectively for the third time, reaching an astonishing D class, and the human race was completely suppressed. On March 7th, the surviving governments jointly established a mercenary guild in the novel, issuing various tasks to allow humanity to have a purposeful development, and I am an elder in the mercenary guild for the time being. On March 22nd, the zombies evolved collectively for the fourth time and reached the D+ level, and humans could no longer bear it, all the human leaders and human geniuses gathered in New York to discuss the use of nuclear bombs, and selected the 5 strongest, everyone called them Human Venerables, that is, the competition I told you before. On March 25, the world's nuclear bombs were launched en masse, destroying about 60% of the world's zombies, and the electromagnetic pulse also ruined human civilization, and all electrical appliances were unusable. Han Chao said this, and also stopped, letting Liu Xin digest this information, and he just drank saliva to rest.

"On March 30th, the darkest day of mankind, the remaining zombies evolved collectively for the fifth time and reached the C level, and the human race no longer had the power to fight, and the remaining 40% of the zombies almost wiped out the human race. On March 31st, some characters from myths and legends appeared, and three of the four holy beasts of Asia came out, except for the green dragon who was nowhere to be found, the white tiger Vermilion Bird Xuanwu wiped out most of the zombies in Asia, and then the three holy beasts disappeared. The European Union has seen the emergence of one of the five guardian dragons in the game, and the legendary 12 constellations of guardian saints have appeared in the Americas. The Egyptian pharaohs of Africa appeared with a large number of mummies. On April 1st, these legendary creatures disappeared again, and only a small fraction of the zombies on Earth remained. On April 3rd, the first ruins of a prehistoric civilization were discovered, and that ruins were actually a pre-apocalyptic game, called Adventure Island, and it was very large, like a new world, in which we learned their techniques for forging weapons, and then we began to look for materials to forge new weapons. Han Chao stopped again, said so many words in one breath, his mouth was a little dry, and he drank a sip of water before continuing.

"On April 5th, the second ruin appeared, they didn't say what their civilization was called, but their refining technology was very powerful, and we got the technology to refine raw steel from them, so that we could make new weapons against mutated creatures. The next thing is that all kinds of ruins are discovered.,Strange everything.,And some of them are various games before the apocalypse.,It's just that the ruins that belong to the game are very rare.,10 ruins appeared.,Only one belongs to the game.。 During this period, there were also various monster sieges, and this time the main force became a variety of mutated creatures, and humans relied on the original steel weapons to defend the monster siege with difficulty. Han Chao saw that Liu Xin was already shocked, and he also stopped and slowed down.

Liu Xin was indeed shocked, but not because of the shock of new technology, but because of the appearance of the game relics that Han Chao said, it turned out that the game era had begun unconsciously, and so on!! Spring City was held because of the addition of Cow Brien, the king of fangs, so is it a long time since the era of gaming began? And now Adventure Island has even appeared in the world of the game, at such an important moment, he is not there, Adventure Island is the appearance of the whole world, so the first person to enter the Adventure Island game ruins must have received great benefits.

"And who was the first person to enter the ruins of Adventure Island?" Liu Xin directly asked the doubts in his heart.

"It's a young man from Country M named Paul, who completes one of these missions and gets the entire space of the Adventure Island Ruins. He also wanted to transfer a base to that game world, but there were a lot of monsters in it, and Paul couldn't bear those monsters at all, and these mutated creatures in the outside world were too far behind the monsters in them. The human beings who survived in it were the mirror images of some of the people of that era, who could only teach Paul some knowledge and could not help them fight. After that, he sealed off that space, otherwise the monsters in that space would rush to the real world. Han Chao also gave Liu Xin's answer, Liu Xin believes that only a few people can know this information, not everyone can understand it.

"Okay, you go ahead." Liu Xin asked Han Chao to continue the rest of the matter.

"On May 4th, the four holy beasts of Asia gathered, and they flew into the sky together from the East China Sea, and they didn't know what they were going to do. On May 7th, for some unknown reason, all the mutated creatures collectively retreated into various large forests, away from the gathering place of humans, and humans got a precious period of reprie. But the inferior roots of the human race were placed there, and as soon as it quieted down, the infighting began, and on June 3rd, the battle between the humans broke out, and the leader of one base grabbed the pearl of the other base and prepared to be the lady of the village, and then the two bases fought. Seeing that someone is taking the lead, all the bases with hatred, or without hatred, and the strength is almost the same, and the bases that are ready to annex the other party are fighting. Because human beings have also evolved twice, the previous hot weapons have been eliminated, and everyone has used cold weapons, and the original governments of various countries have been unable to restrain their bases, and they can't manage them at all. I stopped most of the battles in Country C, so I was called the Martial Emperor, originally my title was Wuzun, Mary Sue organized the war in the European Union, and her bloodline was a vampire, so she was called the Blood Emperor. Don't you see the north of country C, where is the main battlefield, the Harbin base and the Inner Mongolia base are in full swing, as long as you see that it is the people from the other party's base, you will draw the knife, and the central conquest can't control it, so you can only let them fight by themselves, I went to stop them once, but unfortunately they didn't listen. Most of the battles in Country M were stopped by Paul, who had obtained the ruins of Adventure Island, and everyone respectfully called him Paul the Emperor of Light, but it had not yet been officially established. Han Chao said that when the human race started to fight, he was also a little angry, and the danger had not long passed, and the human race started fighting by itself.

Liu Xin is also secretly scolding those people for being stupid, the game era has begun, this is the second wave, human beings actually fought by themselves, but think about it, this information is estimated that only he and the reborn person in front of him can know. The ambition of mankind is unquestionable, because in the end of the world, everyone has gained a certain amount of strength, and no one takes the other into account, and war is inevitable.

"Today is July 7, the end of the calendar year, and they have been fighting for more than a month, and they will regret it soon." Han Chao said gloomily.

"Oh? What do you mean, I know you're a born-again, what happened in the last life? Do you know? Liu Xin asked with a big grin, he didn't know how taboo his question was, if it weren't for his strength being stronger than Han Chao, Han Chao would definitely kill himself in a way.

Han Chao looked at Liu Xin silently, and after a long time of struggle, he said, "I hope you can keep the rest of the matter secret for me." In my previous life, I was just a small character.,I can only get some information that the public knows.,In the previous life, when I was in July of the end of the calendar 0.,I don't know exactly what day.,Monsters came to attack the city again.,But these monsters are not mutated creatures.,But monsters in various games.,They broke a lot of base cities in a row.,Humans finally realized the danger and stopped the civil war.。 Then it was to start dealing with the attacks of monsters in various games, and the human race was defeated one after another, and in the last two years of the calendar, the mutant creatures were killed again, and they had a unified leader, and the earth became a three-way melee. When the three-way fight was in full swing, the fourth force appeared, they were characters in various anime movies, the pattern of the earth changed greatly, and the earth itself became bigger because of the arrival of these worlds. Han Chao said this, his eyes were also full of helplessness.

After that, humanity began to retreat, because when fighting monsters in the game before, humans lost at least half of their numbers, and after the appearance of movie and anime characters, humans were no longer able to bear it. When human beings were surviving in the cracks, alien life came, and it was also the first time you came into the sight of mankind, at that time you led human beings, united mutant creatures and characters from movies and anime, resisted the first wave of alien life, and because of that battle, everyone called you the king of men, which means the king of mankind. After that, you were betrayed by Wang Ling, he united with mutant creatures and killed you in the Pacific Ocean, because the human race lost your leader, the mutant creatures and movie characters did not unite with us, and they were completely defeated in the second wave of alien attacks and became slaves of aliens, only mutated creatures and movie and anime characters are struggling to resist. In order to deal with mutant creatures, aliens sent humans to fight as cannon fodder, and I died when aliens were lined up as cannon fodder on the battlefield. ”
