The angry head teacher nagged Chen Mu for three minutes before continuing the lecture with satisfaction.

"We learned that the first industrial revolution of mankind, powered by steam, is called the steam age; The second industrial revolution, powered by electricity, is called the electric age; The third industrial revolution, driven by the development of the Internet, is called the information age; Up to now, the fourth industrial revolution is underway, and the magic crystal era is the main development force of the magic crystal circuit. ”

After the head teacher's power, no student in the classroom dared to wander anymore.

In 2132, the earth's energy was gradually depleted, and the depletion of energy restricted the development of science and technology. Mankind can only pin its hopes for the discovery of new energy sources in outer space.

After years of development, astronautics finally enabled humans to land on Mars and establish Martian outposts. But the realization of the plan to migrate to Mars is still far away.

Transforming Mars into a habitable planet will not be possible in a short period of time, but the energy crisis is looming, and scientists can only turn their research focus to how to transport Martian energy to Earth.

In 2143, through the concerted efforts of scientists around the world, humans finally mastered wormhole technology.

Humans pooled the resources of countries around the world to build two wormhole generators and conduct space transition experiments in the Sahara Desert.

On the day of the experiment, the world watched the world's attention, and when scientists successfully created two wormholes in the desert and successfully completed the transfer of items, the world cheered for the success of the experiment.

Mankind is celebrating the solution of the earth's energy crisis, and the next step is to launch one of the generators to Mars and install and operate, so that the energy from Mars will continue to be extracted and transported to the earth in the future.

However, there is no next step.

After the wormhole has undergone initial stabilization, it suddenly becomes uncontrollable, creating a huge suction force. Devour everything in the vicinity.

Including two generators, scientists on site, soldiers in charge of vigilance, etc. On that day, humanity lost some of its top scientists.

This day is a nightmare for the whole world, and without this group of scientists, the scientific research capacity of human wormhole technology has been severely damaged.

And the nightmares didn't stop. Humans have opened wormholes, just like Pandora's box. Wormholes began to appear frequently around the world. The wormholes that appear are large or small, the duration is long or short, and there is no law on the time and place of appearance.

People can see the other side of the scenery through the wormhole, there are high mountains and land, there are all kinds of strange plants, it seems to be a wild land, human beings guess that it is a parallel space, a new world.

Just as the nations of the globe are organizing their hands to try to explore this new world, Earth is the first to welcome the guests of the new world, Warcraft. When humans discovered Warcraft, they didn't know that it was the beginning of a catastrophe for humans.

Later generations called that period the "Demonic Calamity Period".

Warcraft is the name given to the creatures of the New World by humans. It was a creature that had never appeared on Earth before, and most of them showed a strong desire to attack humans, and the monsters showed no weaker intelligence.

Most of them use different special energy attacks, which are similar to fireballs, wind blades, etc. It reminds people of Warcraft in fantasy novels.

The world began to become chaotic, and there were constant incidents of demonic beasts hurting people everywhere.

The power of Warcraft is incomparable to that of humans, only large thermal weapons can effectively kill Warcraft, and weapons like pistols are like tickling for Warcraft.

Whenever a monster teleports through a wormhole to a densely populated area, the army often can't use weapons of mass destruction because of the fear of the masses. Every time a demonic beast is killed, it comes with huge casualties.

Human groups are powerful, individuals are vulnerable.

In the long-term struggle with the Warcraft, scientists dissected the corpses of the slain Warcraft and found a special crystal.

The discovery of this crystal, which came to be known as the Magic Crystal, ushered in the Fourth Industrial Revolution.

After research, there will be one or more crystals in the body of all Warcraft, and the volume of the crystals can be large or small.

It's about the size of a pearl and a longan.

The size and number of crystals are directly proportional to the strength of the combat power of the Warcraft, and there is also a certain relationship with the size of the Warcraft.

There are also certain rules for the color of crystals, for example, a monster with a crystal like an emerald color can send out a wind type energy attack, and a monster with a crystal like an amber color can control a certain range of the earth, and so on.

Although humanity has lost a number of top scientists in the Sahara Desert, there is no shortage of genius.

As scientists experimented with this crystal, they were pleasantly surprised to find that this crystal is simply a universal energy source.

The purer the color of the crystal, the greater the energy it contains. Scientists then created a device that harnesses the energy of crystallization, which they called the Magic Crystal Circuit.

The New World has brought great crises to the planet, but also opportunities. Scientists have used the magic crystal circuit to develop a new type of weapon, which is known as the magic crystal weapon.

In 2048, the first magic crystal weapon was released, which made it a little disadvantage in the struggle between humans and Warcraft. For the first time, individual combat can also bring damage to Warcraft.

But after several years of demonic beast rage, the structure of human society has been greatly damaged. Even more terrifying than Warcraft is human desire.

In the face of the wreaking havoc of Warcraft, there were people who watched and helped, and more people killed each other in order to survive, and during this dark time, the global population was reduced by two-thirds.

What really turned the tide in the fight between humans and Warcraft was when the soldiers in the army used the magic crystal weapon for a long time.

A small number of them slowly found that their physical fitness became extremely strong. They can become infinitely powerful, or they can be as fast as thunder and lightning, and even some soldiers can unleash energy attacks without the help of magic crystal weapons.

After discovering this phenomenon, scientists immediately used magic crystals for the study of life on earth.

The results of the study show that the energy extracted by the magic crystal circuit can be absorbed by a small number of humans. The human form did not change after absorbing the energy, but a small portion of the genetic fragments became similar to those of the Monster.

Scientists speculate that this is the reason for the birth of superhumans. However, other earth life other than humans reacted with the magic crystal energy to form an existence similar to that of a demonic beast, and this research was immediately listed as a taboo.

The discovery that the Magic Shard can promote human evolution brings the dawn of victory to humanity.

In order to produce more superhumans, the Crystal Loop has spread to the general public. After all, the larger the population base, the more superhumans will be produced. But this also led to the spread of the magic crystal technology.

It is not that the leaders of the world are unaware of this consequence, but it is a choice that has to be made to solve the human crisis. Moreover, the most advanced magic crystal technology has always been firmly grasped in the hands of leaders of various countries.

All transhumans are organized to work together to defend against the Monsters. They are given birth to a variety of abilities, some weak and some strong. The weak ones may just have better eyesight and better hearing. The strong one is completely a "humanoid monster", which can hunt the existence of monsters alone, and was later called - witch hunter.

In times of war, often the more critical the moment, the more people need heroes.

The Witcher is the hero of the people's minds. And the leaders of various countries did not miss this inspiring opportunity to continuously improve the image of the Demon Hunter and broadcast the heroic posture of the Demon Hunter against the Warcraft.

As the Witcher hunts more Monsters, the more Magic Crystals will be obtained, which in turn will give birth to more Witchers. The fighting continues to move towards a situation that is beneficial to humanity.

It was made to be seen as the end of the war when the space force field stabilizer appeared.

As mentioned earlier, there is no shortage of genius in human beings. Although an accident a few years ago swallowed up a group of the world's top scientists in the field of wormholes, the remaining scientists have made incomprehensible efforts to create a space force field stabilizer that can stabilize the space force field by referring to the wormhole technology and combining the magic crystal circuit.

Powered by a magic crystal loop, the Space Field Stabilizer is shaped like a signal tower and is capable of continuously emitting invisible fluctuations. Within the area of the force field, the space becomes stable again, and wormholes no longer appear.

Immediately after that, humanity began to reclaim the city, building a space force field stabilizer in the city.

The Demon Hunters, on the other hand, attack everywhere to protect the surrounding people and move safely to the big cities. The army built a defensive line around the city to defend against the monsters that might break in......
