On the vast night sky, it was dark, deep and mysterious. Suddenly, ripples appeared, forming a vortex circle by circle, and slowly elongated into a vortex channel.

    This channel, like a black hole, seems to connect another world, cold as a ghost. At this time, if someone saw it, he would scream loudly, because something suddenly flew out of the dark, deep and seemingly endless vortex channel.

    This thing is like a meteor. It falls down quickly. Because of the speed, the friction with the atmosphere forms a layer of air flow outside this thing. Strangely, it doesn''t make any sound.

    The airflow is black, almost like the night, so it is difficult to see it even if you look at it.

    I don''t know whether it''s lucky or unfortunate. This thing fell down towards Tang fan''s forehead, vertical in a straight line.

    With emotion, Tang fan suddenly looked up at the sky. It was not what he found, but just a subconscious action.

    "Ah..."

    With a scream, Tang fan fell to the side and fainted.

    A blood hole opened in the forehead, and the blood gurgled out. The thing fell on Tang fan''s forehead, revealing the prototype. It looked like a piece of metal.

    The blood was first-class on the metal. A strange scene happened. The metal was like a sponge. It absorbed all Tang fan''s blood and didn''t fall to the ground at all.

    Then, with a buzzing sound, a layer of gray light was emitted from the metal. The whole metal flew up and suspended over Tang fan. It turned out that the metal was a book.

    The gray light covered Tang fan''s whole body. The gray light continuously penetrated into Tang fan''s body, and a shocking scene appeared.

    Under the gray light, Tang fan''s appearance changed dramatically. His black hair was like a wild grass that had lost water. It became boring and seemed to shatter at the slightest touch.

    The skin gradually loses its luster, becomes shriveled and shriveled a little, and the face grows old quickly. The original smooth skin shriveled like withered old bark in just a few decades, with sunken eyes and cheeks and protruding cheekbones, leaving only a shriveled and wrinkled skin wrapped around the skull.

    Not only the head, but also the body and limbs. The hands exposed outside the clothes are as thin as bird claws, and the finger joints are seriously protruding.

    At this time, Tang fan was like an old skin wrapped with bones, which was very terrible, enough to scare the timid people to death.

    The gray light didn''t stop because of Tang fan''s change. The light shone on him and drilled into his body through his clothes along the skin pores.

    In Tang fan''s body, if he could look inside, he would see gray airflow as thin as silk thread, flowing rapidly towards his chest.

    Where I passed, all the muscles lost water, the blood seemed to dry up, the bones became gray, full of holes, serious lack of calcium, and the internal organs shrank constantly, as if they were exposed to the sun for ten days and nights.

    It can be said that Tang fan at this time was on the verge of death, and only an extremely weak breath proved that he still had a glimmer of vitality. If it were not for the solid foundation laid by soaking medicine juice to exercise when he was a child, his physique would be much stronger than that of ordinary people, and he would not last long.

    However, if this situation continues, I''m afraid it won''t take a minute for Tang fan to die, and then it will become another new thing in Linjiang news program tomorrow night, and another conversation for people after dinner.

    In the body, the gray air flow gathers in the Tanzhong hole on the chest, gradually forming a nebular vortex. More and more gray air flow is sucked in by the gray nebular vortex, and the speed is faster and faster.

    Tang fan''s breathing weakened again. He was only one step away from falling into death completely.

    At this time, the gray light disappeared into Tang fan''s body like running water, and the book fell automatically and rolled aside motionless.

    The gray light was lost, and all the gray airflow in his body was absorbed by the nebula vortex at Zhongdan field. Tang fan''s breathing gradually returned to normal. Although it was very slow, he was separated from the edge of death step by step.

    The nebula vortex continued to rotate. At Tang fan''s lower Dantian, there was a white air flow. The original motionless air flow seemed to feel Tang fan''s crisis at this time and suddenly threw out several channels. These air flows quickly swept Tang fan''s internal organs, bones, muscles and even skin.

    Then, the internal organs, skeletal muscles and even skin recovered their vitality little by little. The internal organs were like the rain on the dry land for three years, and the holes in the bones disappeared rapidly, and the muscles and skin gradually recovered their fullness.

    The wound on the forehead was smashed out, and the meat on it slowly wriggled, as if there were countless insects in it. It looked disgusting, but in just a few minutes, the wound on the forehead healed completely and was smooth, and there was no sign of injury.

    Withered wild grass like hair, black and bright again, looks even more energetic than just now.

    Tang fan''s breathing recovered smoothly, like a sleeping person, who seemed to have a dream. He grabbed his hair, turned over and continued to sleep.

    Maybe something was wrong when he turned over. Tang fan suddenly opened his eyes, and then got up quickly. His action was fast and sensitive, which was more agile than martial arts action films.

    But Tang fan didn''t notice that his skill seemed more sensitive than ever.

    "Which dead man dares to hit me with something? Oh, it''s still such a heavy thing. Don''t you know that if you hit it directly, you''ll die." Tang fan scolded, grabbed the book at his feet, started to sink, and let Tang fan scold again: "damn bastard, if I know who hit me with this thing, I''ll have to peel your skin."

    After scolding a few words, no one responded. Tang fan also felt boring. He simply shut up and grabbed this heavy thing and returned to the house.

    ……

    "The book of the dead? What the hell."

    Sitting on the sofa, Tang fan holds the book that hit his forehead in both hands. The whole book is gray, 16 Kai, as thick as a modern Chinese dictionary, and weighs more than five kilograms. The cover seems to be made of some kind of metal, dull.

    There are four big characters on the cover. It''s weird. It feels like a picture symbol. I can''t understand it at all.

    But what''s more strange is that I clearly can''t understand what the word is, but I just understand the meaning of the four words: the demon code of the dead.

    His fingers touched the cover, and his tentacles were cold, which made Tang fan shiver uncontrollably.

    Simply open the book and the first page is the table of contents.

    "Hell demon... Summon... Poison and bones... Curse... Magic props... Pharmacy... Magic array, eh, what is this?" Tang fan felt more confused the more he read. It was clear that he couldn''t understand the twisted words, but he just knew what they meant.

    "Hell demons..." Tang fan turned the page again and saw a few big words. Another one was a distorted text: "hell demons are a very aggressive and destructive race..."

    The general meaning of this paragraph is that the hell demon family is a race with a long life. For them, it is no different from snapping a finger for thousands of years. Therefore, in a long time, the demons always have to find something to do.

    The aggressive and destructive nature in their bones makes these demons keen to invade other planes, occupy them, enslave them and expand their territory. So far, thousands of planes have been successfully occupied under the continuous attack of hell demons.

    Hell demons, when staring at a plane, will first create some accidents. The most common means is meteorite falling, invading the target plane with the unique smell of hell.

    When the concentration of magic gas reaches a certain level and the projection suitable for hell demons comes, demons will invade on a large scale. Usually, this period of time is about 30 days.

    "Thirty days, that is, a month. If that meteor shower is the meteorite shower made by the so-called hell devil, then the time of hell devil''s arrival is... The eighth day from now!" Tang fan was suddenly shocked, then patted his head and smiled bitterly: "it seems that there are too many strange things. Even I think the end of the world is coming."

    Indeed, although the so-called demon code of the dead came very strange, and although strange things have happened frequently in the past month, Tang fan still couldn''t accept it if he wanted to believe that it was a precursor to the invasion of hell demons.

    After all, from small to large, his education, that is, science, immortals, demons, ghosts and so on, are fictional. For more than 20 years, he had such a concept. Suddenly, a book told him how to believe that hell demons were going to invade.

    Maybe it was boring. I don''t know why. Tang fan opened the book again and continued to read it.
