As soon as a person's heartbeat stops, the blood stagnates and the cells in the body begin to die gradually after a few minutes due to lack of oxygen. The external environment can greatly affect the rate at which a body decomposes, and the human body usually ulcerates a few days after death, and the microorganisms in the intestines begin to break down the abdomen from the inner part of the body, while bacteria called Clostridium bacillus and E. coli begin to devour other tissues in the body.

The decaying corpse usually gradually turns green, and some substances and gases released by the corpse will make its skin swell and bubble, and after a few weeks, the hair and nails will fall off because of ulceration, and after about half a month, the body tissue begins to liquefy, only a few cells and tissues are still attached to the skeleton, and the flies lay eggs on the corpse, and naturally hatch into larvae under the air, which is the corpse worm.

.....

Qiu Yan glanced around vigilantly, and suddenly saw a red light flashing at the exit. The little spark drew a graceful arc in the air and quietly landed, only to hear a 'boom' sound in the ear, and the little spark turned into a raging fire and quickly devoured it.

"Bastard! It turned out to be the smell of gasoline, and people were sprinkled with gasoline all over the ground, no wonder the smell was so familiar! Qiu Yan was frightened and didn't forget to scold, and ran towards the depths of the cave as soon as he pulled the little third son. Hurry up, you'll die if you're late! The air here is humid and moist, so there must be a river or a pond nearby. ”

Sure enough, in the depths of this cave, there are many pools of water, the water quality is clear with a hint of turquoise, Qiu Yan grabbed the little third son and struggled hard, rolled randomly, and turned around twice, only to hear the sound of 'bang', and the two fell into the water.

The faint waves of water shook violently, countless large and small transparent bubbles appeared in front of him, and the piercing sensation approached his body from all directions, slowly suppressing the terrifying and fierce burning sensation.

This pond was much deeper than expected, but the size was just like that, Qiu Yan couldn't even straighten his body in the water, so he just hugged his body like that, like a frightened child, hiding in the silent water, letting the waves flow and wash his body.

Qiu Yan and Xiao Sanzi shrunk tightly, hiding in this water, and did not show their heads for a long time, in this silent water, his thin lips seemed to tremble slightly, he slowly raised his head, looking up from underwater, the water rippled with fiery red light, it was a vague other world, as if he could never see clearly, and there was no end in sight. The fire continued to spread through the cave, and the fiery orange-red tongue of fire slowly consumed Hu Xinrui's corpse. The corpse began to curl as it was burned by the fire, as if it was Hu Xinrui's unwilling roar, burning, and emitting an astonishing scorching stench.

"Cheap woman, you were toyed with by me between applause before you died, and you can't live in peace when you die, what can you do if you turn to ashes this time!" Outside the cave, intermittent and unbridled laughter greeted in all directions, sounding like Mu Yufei's voice.

.....

The cave was already damp and there was nothing to burn, and the gasoline burned out and the fire gradually went out. Qiu Yan and Xiao Sanzi gushed out of the pool of stagnant water and lay on the ground, desperately absorbing the few gasogens in the air. Suddenly, the sound of footsteps came from far and near, and the man seemed to notice something strange and hurried in.

"Sister!" The slender figure exclaimed in surprise, it was Juanya.

"Sister! How so, what the hell is going on? Juanya fell to her knees in despair and muttered to herself, her lips trembling in pain.

"Mu Yufei, that bastard, spilled gasoline in the hole..."The little third son walked over and wanted to help her up.

Juanya mustered up all the strength to push him away, screaming. "I don't believe it! It's you, it must be you, you listen to the rumors and think that my sister will turn into a ghost and ask for her life, so you set it on fire! Give my sister back! She was so gentle and considerate when she was alive, and she never did anything hurtful, but you hypocritical guys all have to treat her like this! ”

Juanya slapped Qiu Yan's chest hard, Qiu Yan grabbed her hand, raised her palm and slapped her hard, and shouted angrily. "Enough! Your sister is already dead, she's dead! Why are you still so obsessed? Who can't tell the difference between rumors and lies! ”

Juanya slowly turned her cheeks sideways and looked at Qiu Yan emptily, her eyes filled with death.

.....

At four o'clock in the morning, the night was as thick as ink, and when the light of the morning sun had not yet set again in this quiet little village, everything was so dark and so unknown.

Qiu Yan and the third son each performed their duties, carrying a person and a corpse, and returned to the hostel exhausted. Hu Xinrui's body was badly burned, and many places left charred and dry bones, which was simply unrecognizable, which undoubtedly added to the already decomposed corpse, which became even more ugly and ugly.

Qiu Yan discussed the follow-up with the third son, settled down one person and one corpse, and said goodbye to each other.

Returning to his guest room, he fell heavily on the soft mattress, and couldn't help but let out a groan, and suddenly a knock on the door interrupted his thoughts, Qiu Yan got up very reluctantly and opened the door.

"Who?" Qiu Yan was stunned, there was no figure outside the door. Qiu Yan stretched out his head and looked left and right, only to see that the dim orange light in the corridor became even darker, and there was a cold mist all around, constantly coiling and churning, indescribably eerie.

"Hey, this is. Dry ice!? (Dry ice is solid carbon dioxide, which condenses carbon dioxide into a colorless liquid at a pressure of 6250.5498 kPa, which is non-toxic and odorless, which explains the 'cold mist' above.) Carbon dioxide can not be seen, in fact, it is not smoke, it is water mist, carbon dioxide absorbs heat in the air when it is solid into gas, which can make the temperature of the surrounding air cool quickly, the air temperature drops, its solubility to water vapor becomes smaller, water vapor liquefaction reaction, release heat, it becomes a small liquid, that is, fog, this and summer popsicle white fog is the same meaning. Qiu Yan wanted to walk out of the room, but immediately dispelled this thought, it was so cold! The mist was like life, constantly emitting a large amount of cold breath, and the skin exposed to the clothes began to numb and dry as soon as it came into contact, as if all the moisture was greedily absorbed.
