Looking at the thick clouds outside the window of the plane, Qin Kai remembered his experience in Izumo, Japan, two years ago.

On June 5, 2017, the sun was shining and a trace of hot wind blew. Today's temperature is as high as 35 degrees, giving it a stuffy feeling. At this time, Qin Kai was blowing the air conditioner in the dormitory, reading novels, and his roommates were all out to play basketball. There was a rush of footsteps, and a boy with a computer and glasses on his right hand ran forward.

He ran all the way to room 163 and knocked on the door, "Is there anyone, Qin Kai is not here." Qin Kai put down the novel, put on his slippers and walked straight to the door, and opened the door, "It's Xiaoyu!" Is there something wrong? The person in front of him, wearing a white short-sleeved shirt and army green slacks, and a pair of glasses, is Mao Chengyu, a hacker.

Mao Chengyu sat on Qin Kai's bed panting, put the computer on the table, Qin Kai took out a bottle of mineral water for him to drink, "Say it slowly, what is the matter?" ”

"Qin Kai, you have been chosen!" Mao Chengyu drank all the mineral water and said excitedly.

"What the hell is going on! Look at you. ”

Mao Chengyu stood up, came to Qin Kai, held Qin Kai's shoulders with both hands and said, "You have been selected, and you will go to Japan for study and exchange!" You're the only one in the whole school! ”

"Ahh Just, just me, going to Japan? Learning to communicate? Qin Kai stood in place with an incredulous expression, and didn't come back to his senses for a long time.

"It's true, just wait for the official announcement."

"Where did you hear that?"

"I came out of the classroom just now, and I heard Teacher Chen and the principal discussing in the office about preparing to send a representative to Japan to study and exchange, the two of them discussed for a while, and finally decided that it was you, Qin Kai."

"To Tokyo or somewhere else?"

"Then I don't know." Mao Chengyu spread his hands.

"Can you hack into Mr. Chen's computer and check the information."

"Mr. Chen upgraded the firewall, and as soon as I entered, he would immediately notice it, and then find me according to the computer IP."

Qin Kai snorted and laughed, "Aren't you known as the little prince of hackers?" Why, even you can't do anything. ”

"Isn't there a final exam? I wanted to hack into his computer to see what my score was. If the passing grade is changed to a slightly higher level, if it does not pass, it will be changed to a passing grade immediately. I really didn't expect that when I was about to succeed, my computer screen prompted that there were three minutes left, and he was about to find you, so stop the attack quickly, otherwise the consequences will be serious. ”

"And then? You're just going to stop attacking? ”

"I thought it was bluffing, but I didn't expect an eye to appear on my screen, just staring at me so directly, I was panicked when I saw it, so I stopped attacking."

"Does that eye look horrible?"

"It's really terrifying, blood and tears flow from my eyes, and my cold hairs stand up when I see it."

"The Eye of Death." Qin Kai muttered to himself.

"What do you say? What eye? ”

"Nothing. No wonder you failed the exam after that time, I still wonder why you changed your score every time before, why didn't you change it that time, and you didn't say the reason when I asked you, so that's the case! ”

"Later, I found out that he found a master to help him upgrade the firewall and system, in order to specifically defend against hackers like me."

Qin Kai picked up the novel on the bed, "If it's true, then I guess Mr. Chen will come to me in a while." ”

There was a knock on the door, "Is Qin Kai in the dormitory?" ”

"No, is it really me?"

Qin Kai opened the door, and a man wearing glasses and shaking a fan in his hand, who looked to be in his early thirties, walked in, he was Chen Guangming, and Teacher Chen was also the head teacher. He looked at Qin Kai and said, "Qin Kai, come with me to the office." ”

"Okay."

Chen Guangming glanced at Mao Chengyu and shook his head helplessly, "I said Mao Chengyu!" You better hurry up and study hard for me, when the time comes, I will fail the credits and I won't be able to complete my studies, don't blame the teacher! ”

"Don't worry, Mr. Chen, I will definitely pass!"

"Don't use your brains this time." Chen Guangming pushed his glasses, "Let's go, Qin Kai." ”

"Xiaoyu, I'm leaving." After Mao Chengyu made an OK gesture, he turned on the computer and tapped on the keyboard.

Three minutes later, the knock on the door sounded again, and Mao Chengyu opened the dormitory door, "You're back so soon?" Are you going to Japan confirmed? ”

"It's decided, I'm the only one in the whole school."

"Tokyo?"

"It is Izumo City, Shimane Prefecture, Japan. Depart in a week. ”

"During the time you went to Japan, I want to raise my level to a higher level and break his firewall as soon as possible."

"Then come on, I'm going to start preparing."

As the sun set, the sky darkened, and Qin Kai walked out of the campus and came to his house. I opened the door, went straight to the living room, took a copy of the White Night Walk from the shelf, and looked at it.

The sky was full of lightning and thunder, dark clouds, one after another lightning illuminated the sky, accompanied by thunder and thunder, which resounded through the sky, making people frightened when they heard it. Children are crying, and adults are comforting. A man ran forward as fast as he could, muttering:

"It, it's resurrected." He fell to the ground, turned his head to look at the lightning-lit spot opposite, where something writhed, and in a moment crawled in front of him. Its eyes were as red as red sauce, its back was covered with moss and trees, its belly was festering and bleeding, and its head was covered with eight-colored clouds, and its body was as large as eight peaks and eight valleys. Eight tails wagging in the back.

It lifted eight hideous heads, and looked at the man with bright red eyes. The man was frightened and quickly lowered his head, "I, I didn't mean to offend you, please bypass me this time." His body trembled slightly, and the sweat on his face kept dripping. The thunder and lightning grew louder and louder, and it raised its head and screamed, then aimed one of the eight heads at him.

It opened its bloody jaws and bit at him.

"Ahh The exclamation was mixed with thunder and lightning, "Help, who will save me!" Yes!!! ”

A week later, Qin Kai packed his luggage, and after saying goodbye to Mao Chengyu and others, he got on a plane to Izumo City, Shimane Prefecture. I thought it would be a simple learning exchange, but I didn't expect to get involved in a case, and get a Japanese detective, the ancient legend, is it really resurrected? What will be waiting for Qin Kai?

Legend has it that Susanoo used sake to lure Yaki Orochi, who drank all the wine in the eight vats and fainted. Susanoo grabbed it the moment it was drunk, pulled out the ten-fist sword, cut off its eight heads, and was about to slash at its abdomen when the ten-fist sword hit a hard object and cracked a corner, he cut open the abdomen, and took out a sword from it, Susanoo named it, and it was called

Sky Cloud Sword.
