What you see, hear, and think may not be true. ———— Scholars Association

The lecturer is Teacher Xue Wen, who is full of knowledge as his name suggests.

Xue Wen is not an ordinary person, but he is only a junior spiritual priest, and he is too old to have any possibility of progress. In this school, where the minimum requirement for teachers to enter is the requirement of a senior spiritual master, except for the master who guards the door and the handyman in the school, he is the weakest in strength, and he is a special existence because he is a scholar.

This class is a cultural class, and he talks about the generation of Reiki and the history of the Spirit Continent.

It is rumored that there was a society with advanced scientific and technological civilization before, more than 300 years ago, a large black hole of tens of thousands of zhang suddenly cracked in the sky of the sea in the south of the continent, the entrance of the hole and the sea surface, the black hole around the continuous fragmentation and bridge, this kind of black hole was later called the space channel.

A large number of spirit beasts poured out of the space channel, and the spirit beasts that appeared were extremely aggressive, but these spirit beasts were all injured, and they appeared on the sea, these spirit beasts were temporarily unable to reach the place where humans gathered through the barrier of the sea, and human beings did not have a way to close the channel, and later by detonating the thermal weapons of mass destruction, the human beings eliminated the spirit beasts that appeared, and the channel began to break, and there were no spirit beasts pouring in again, but it caused another disaster, which was called the disaster of the ten days of heavenly change.

Just after the weapon was detonated, the terrifying space channel shattered into thirteen large or small black holes, which instantly appeared all over the continent, and streams of invisible energy diffused from the mouth of the black hole to the heavens and the earth.

This energy is invisible but swings like a wave, colorless but visible. The world began to awaken to certain rules when it came into contact with this energy, as if the seal had been broken, and began to agitate.

The Ten Days of Heavenly Change is not all a disaster, but the world has changed dramatically in ten days, to be precise, the Ten Days Disaster is half destruction and half creation.

They are fire, thunder, wind, earth, ice, gold, water, light, wood, and darkness.

On the first day of the 10th day of the change, the whole world heated up, the world was full of fires, unexplained spontaneous combustion everywhere, even people's hearts were burning with nameless fire, the city was full of wolf smoke, the forest was also lit up with flames, the strange thing is that the flames are particularly strong, it is difficult to extinguish. Just when people were at a loss, that night, all the flames were extinguished in an instant.

The second day began, the sky was dark, not the lack of light, the sky was shrouded in thick lead clouds, layered as if the whole sky was pressed overhead, flickering thunder and lightning shuttled in it, the thunder and lightning were dense, like endless cobwebs superimposed together, the thunder echoed between the heaven and the earth, to tear the day apart, and even small electric sparks began to wander everywhere in the world.

On the third day, the clouds dispersed and the wind rose.

This wind does not come anywhere, but the more it blows, the more outrageous it becomes, the more it blows, the more weird it becomes, so weird that people can't figure it out. The wind stopped in the last second, and the next second people flew, and the lucky ones may be thrown into the air, thinking that my life is at stake, and at the moment of landing, they are caught by a gust of wind and gently placed on the ground, just like a naughty child playing with toys.

On the fourth and fifth days, the deadliest two days were the deadliest, on the fourth day the earth began to shake, crack, volcanoes began to erupt, the red-hot magma flowed wantonly along the cracks in the earth, the originally solid cement city was as fragile as white paper, there was no hard object in the world, and the smoke and dust that rushed to the sky brought up countless dust and gravel quilts, obscuring the sky, and the world lost its sunlight again and became gray.

On the fifth day, the temperature began to drop wildly, and the temperature dropped very quickly, thousands of miles of ice were frozen in one day, everything froze, and life died in this silent silence, which made human hearts freeze with a layer of frost that could not be dissolved. The five-day catastrophe had decimated the human population by more than half.

When humanity felt that the end of the world had completely appeared, hope came, and on the sixth day, the dust in the sky began to fall or dissipate, the clear sky appeared, the lava cooled, and a large amount of metallic substances were produced, and the known existence and texture of these metals were very different from the previous ones, and more belonged to new metallic substances that had never been seen before.

In order to use these new metals, mankind began a hundred years of exploration, and the reason for this exploration was that mankind had to study the use of these metals.

On the seventh day, the clouds began to converge, the rain sprinkled from the sky, from morning to night, from small to large, the rain fell for a whole day, completely washed the clean world, as if to wash away the layer of shadow that people face the disaster in their hearts, the world after the heavy rain is extremely clean, due to the discovery of science and technology brought about by the air pollution was completely washed away by the heavy rain without a trace.

The eighth day of light, also known as the day of the descent of God, was later recognized as a great day by the Church of Light.

If it weren't for the next two days, they wouldn't even want to admit that this day was the 10th day of change. On this day, human beings finally felt the presence of the sun, the sunlight shone on the earth, and also on human beings, illuminating all the dark corners of the world, this light has the power to heal everything, and those who were injured in the disaster began to be slowly healed under the illumination of the sun.

The sun is not too blazing, warm and satisfying, compared to the turbulence of the fourth day and the cold silence of the fifth day, this day seems to be the world is heaven.

After the light of day, everything grows, plants seem to go crazy, growing at a speed visible to the naked eye, some trees even grow in a day for decades, and begin to change greatly, and even many plants that do not belong to this world appear, they begin to have signs of self-consciousness and wisdom, preying like animals. It is clear that the old plants began to mutate and evolve, and the new plants began to adapt and grow.

One of the most ordinary and magical two days of the Ten Days of Changing Heavens is the Dark Advent Sun, on this day there is nothing terrible happening, because it itself is terrifying enough, on this day, the whole world is plunged into darkness, not the darkness that covers the sky, it is as if the world is shrouded in black fog, human beings are closed to all perception, you can't sense anything, including the flow of time, all you can feel is absolute silence, so quiet that you don't even feel your own heart beating.

If a person is in this environment for a long time, he will definitely have a nervous breakdown, but because he can't feel the flow of time, the day passes quickly as if it were in an instant, but that feeling is deeply remembered by everyone.

Ten days later, the world has changed, the air is so fresh that you can't believe it, and there is a gas with plenty of energy, which makes people feel comfortable between breaths, and human beings have found that this gas has a magical effect, and some people can absorb and manipulate this energy, resulting in many magical means, even if the people who can't control the energy, their bodies begin to become stronger and stronger. Humans call this magical energy Reiki.

And according to the special attributes of the ten-day change, the aura was classified, and just as the human race began to rejoice, the thirteen spatial passages scattered around the world formed after the shattering, ten of them began to pour into a large number of new spirit beasts. This was the first beast tide that swept the earth in the true sense of the word. The types of spirit beasts are strange and strange, different in size, some like to divide the territory, the territory is relatively peaceful if it is not invaded, and some are cruel and easy to kill. When they encounter a creature, they chase after it just to kill and devour it.

The spirit beasts that appeared were all kinds of scales and feathers, and they could even control this magical energy, but they used very little, and most of the beasts relied on their strong bodies to kill humans.

In the face of the threat, humanity has to break the dream and start fighting back, and the newly acquired means, although magical, are still weak and ineffective.

However, it is bad news that high-tech and thermal weapons are starting to have problems, and even cannot be used or hurt themselves when they are used, because the use of weapons will attract magical energy between heaven and earth, such as gunpowder firearms and weapons, which will trigger fire aura at the moment when the fuse is ignited, and will cause an explosion before it is discharged.

In the same way, all energy-driven weapons begin to slowly be scrapped, which is one of the major characteristics of Reiki - infectivity.

It's that the aura will be integrated into all the matter, the living beings, and change in essence, such as making the metal harder, making the animal stronger and smarter.

The reason why this method is called infectivity is because you can't refuse the process of aura infection, you can only passively accept it, and aura is like ordinary air, it is everywhere, even if you pump an area into a vacuum, aura will exist in it.

In order to eliminate the first beast tide, the human race finally sacrificed all modern weapons, and even some of the spirit beasts scattered in the world were powerless to exterminate it, and in the face of the space passage that would gush out a few spirit beasts from time to time, the human race was completely helpless. Weapons that are reproduced will be completely unusable due to the impregnated nature of the aura.

Fortunately, the aura greatly enhanced the performance of metal, and mankind began to re-enter the era of cold weapons.

Although these descending spirit beasts are terrifying, after killing them, they have spirit beast pills in their bodies, these spirit beast pills can speed up people's cultivation, the blood and flesh of spirit beasts can strengthen the body to assist in cultivation, and the bones and skin can forge powerful cold weapons.

Human beings are also divided into nine levels according to the strength of spirit beasts, corresponding to the nine levels of human cultivation, but most spirit beasts have rough skin and thick flesh, and it is difficult for humans to face a spirit beast alone in the same level.

Fortunately, most of the spirit beasts have low IQ, and the spirit beasts of the same race will gather together, and the spirit beasts of different races will also fight with each other.

Later, under the slaughter of these terrifying spirit beasts, they could only continue to shrink the living space, huddle together for warmth, they reluctantly established a settlement, but in the face of the decreasing number of human beings day by day, people were completely confused for a while, and they didn't know where to go, until two other things happened...
