The endless sky, blue and magnificent, atmospheric and majestic, the sun slid to the horizon, blooming the last afterglow, making the whole sky seem to be covered with a layer of gold.

Gangnam Base City, Lingnan High School.

"Jingle Bell ......"

The day's study was over, and a large number of students rushed out of the twelve-story teaching building, and the square downstairs was soon crowded with people.

The crowd surged, and two long queues automatically diverted out of the square, one leading to the school gate, while the other ran to a building opposite the teaching building.

This building is not high, only five floors, but it covers an extremely wide area, only the solemn and heavy big iron door, there are more than four meters high, more than eight meters wide, there is a huge golden plaque hanging above the door, shining in the sunset, on which the dragon flying and phoenix dance are engraved with three big characters - Yanwutang!

In the center of the square, a young man with a height of nearly 1.8 meters and a delicate appearance looked at the students who entered the Yanwu Hall, and his heart was full of envy.

"It's been six years, I've been in contact with Yanwutang since junior high school, and it's been almost six years now, when will I be able to walk in here without any scruples like everyone else?" the young man's name was Cao Ye, muttering to himself at the moment.

The state stipulates that any junior high school or above must set up a martial arts hall, and students can enter it for free training.

Of course, this kind of training is completely voluntary, if the students themselves are unwilling, the school will not force it, the martial arts are extremely difficult, and not everyone has the perseverance to persevere.

Cao Ye is naturally not unwilling, but unable, he has a last resort.

"Didi ......"

The celestial news on his wrist suddenly sounded, interrupting Cao Ye's thoughts.

[Aye, where are you? Wait for me!]

This is a message from Cao Ye's good brother Li Heng, the two have been classmates since elementary school, and then went to the same junior high school and the same high school, although they are not in the same class now, their relationship has always been iron.

[Waiting for you at the school gate, ten minutes, I can leave if I don't come. 】

Cao Ye quickly edited a message and went back, this kid sent a message at noon, saying that he wanted to surprise him, so that he must wait after school, looking mysterious, but he still had to rush to Brother Biao to get the goods.

Glancing at the golden plaque one last time, Cao Ye turned his head and left, the closing time of the Yanwutang was an hour later than the end of the school, but it had nothing to do with him, he walked straight towards the school gate, and a few girls walked side by side, his eyes couldn't help but be attracted by one of them.

Yun Xi, Cao Ye's classmate, a very beautiful girl with a good personality, is the goddess in the hearts of many boys in class 302.

"Hey, Cao Ye, why did you get out of class so quickly today, I originally wanted to ask you a few questions. Yun Xi also saw Cao Ye, and after signaling a few girls next to her not to wait for her, she walked over with a textbook in her hand.

"Something happened today. Cao Ye said with a smile, although he failed to practice martial arts, his performance in cultural classes was very good, and he deserved to be the first in the age, and he was also a strong contender for the top prize in the national college entrance examination two months later, "If you have any questions, why don't you ask now, I'm waiting for someone, just a few minutes." ”

"That's good, that's good. Yun Xi smiled, and a pair of cute little dimples couldn't help but appear on his face, "It's a problem in history class, mainly a period of history before and after the Black Iron Age, I always can't remember the time, and it's easy to confuse them." ”

"Oh, this history, it's actually very easy to remember, you just need to remember a few key numbers. Cao Ye gestured with his hand and said, "First it was 3034, then 22, and then 15, as long as you remember them, this history will not be confused." ”

Learning should pay attention to methods, especially rote memorization such as history, if you can't find the right method, some time points and things are really easy to get confused.

Yun Xi hurriedly took a pen to write down these numbers, and Cao Ye explained further.

"3034 represents the year, the most tragic black iron age in human history, it is from this year, things about the black iron age are more complicated, remember the test point, its origin is because the earth's resources are overexploited by human beings, the environment is seriously damaged, and there is thick dust floating in the atmosphere, which causes the world to be dark, science and technology are unusable due to the depletion of resources, and human beings finally return to the primitive state of life, so it is called the black iron age. ”

"The 22 years before 3034, the period from 3011 to 3033, on the contrary, was the most glorious period in human history, which is probably the so-called boom and fall, when technology was very advanced, and several great inventions during this period must be remembered, such as interstellar speeders, laser cannons, and spaceships. ”

"Then there is 15, 15 represents the duration of the Black Iron Age, in which more than 80% of the Earth's population died, and it must be remembered that its end event was 3049, when the Bermuda wormhole appeared. ”

"Understood, it should be easier to use this method to memorize, right?" After some explanation, Cao Ye looked at Yun Xi and said.

"Hmm...... It's really much easier!" Yun Xi looked excited, secretly saying that such a simple learning method, why didn't she think of it?

"By the way, Cao Ye, about the Bermuda wormhole, I think the last question of the college entrance examination paper may involve some, can you tell me about it?"

"Bermuda wormhole...... Cao Ye thought for a while and said: " In fact, it is a space-time tunnel that links two multi-dimensional spaces, one is the earth, and the other is called the monster planet by scientists, the wormhole opens every ten years, and a large number of monsters pour into the earth every time it opens, these monsters are the saviors of mankind, it is they that bring inexhaustible energy to mankind, end the black iron age, and avoid the extinction of human beings, but monsters have also brought endless disasters to mankind, and it is precisely because of the Bermuda wormhole that human beings will build the eternal wall and enter the era of base city. ”

"Hmm...... In addition to these, some of its characteristics also need to be understood, such as it is a one-way wormhole and does not have the ability to pass through both sides, so all matter on the earth will be repelled when it enters it, and every time it is opened, it will last for about five minutes, etc. ”

"Wow, Cao Ye, you know so much, what kind of explanation of a one-way wormhole, it doesn't seem to be in the textbook, right?" Yun Xi said with some admiration.

"Actually, it's nothing, it's all from scientific magazines. Cao Ye smiled and said, "Okay, it's about time, I'm leaving." ”

"Well, thank you, bye-bye. ”

After greeting Yun Xi, Cao Ye turned around and left, but what neither of them noticed was that when they were chatting happily just now, in a corner of the square, a boy who was gorgeously dressed and looked quite handsome, but there was a kind of gloomy meaning on his body, secretly stared at them for a long time.

Cao Ye stood at the school gate and waited for a while, and the ten minutes agreed with Li Heng would arrive soon, so he didn't plan to wait any longer, after all, if he offended Brother Biao, one of the bigwigs in District 19, the consequences would still be a little serious.

But the footsteps have just moved......

"Ano be careful!"

Hearing a sudden sound from behind, Cao Ye turned his head sharply, and then quickly dodged to the side, at this time, a blue and white interstellar speed car just flew past his body.

"Grass! Zhao Tingkai, you give labor and management!" A young man who was slightly shorter than Cao Ye, but whose body looked more sturdy, stepped on a flying skateboard under his feet, and rushed from behind at great speed.

"Li Heng!" Zhao Tingkai glanced at the visitor, and knew that the plan to make Cao Ye suffer a little bit today was about to come to naught, this kid knew that he was pursuing Yun Xi, and he was so close to her, he simply didn't take himself seriously!

But now that Li Heng has arrived, he can't help it, unlike Cao Ye, a white melon, Li Heng's combat power is not weaker than him at all, and he is also a junior student of Yanwutang.

White melon - people's name for people who cannot practice martial arts, with derogatory connotations. After all, in the era of Base City, the genes of human beings evolved very well, and there were really not many people who couldn't practice martial arts.

Of course, it is extremely difficult to become a real martial artist, it is easy to say that it is one in a million, and most people are just martial arts students all their lives.

"Hmph!" Zhao Tingkai snorted lightly, and drove his beloved Knight series flying car and climbed into the air.

"Don't chase it, your thing has a height limit of ten meters, and other people's interstellar cars can fly up to thirty meters high, chase a fart?" Cao Ye saw that Li Heng was about to rush up on a flying skateboard, and quickly called out to him.

"Damn it, a rich dog calf!" Li Heng scolded angrily, if he hadn't arrived in time just now, and Cao Ye's reaction was quite fast, then he would have to hang up some color.

"Okay, don't be angry, this guy hasn't been upset about me for a day or two, when have you ever seen him take advantage?"

"Huh?" Li Heng was slightly stunned, and then smiled, yes, who is Cao Ye? This guy was spanked by a female teacher when he was in elementary school, and he dared to cross his neck to peek at other people's bottoms.

"Haha...... With you, what are the new tricks this time?" Li Heng jumped off the flying skateboard and patted him on the shoulder and asked.

Cao Ye smiled, and then handed him a small bottle in his hand.

"Damn! Demon spray, ruthless enough!"

The original intention of the inventor was to use it for students to change their homework, and later found that the effect was wonderful, so they simply upgraded it, and now it is widely used in all walks of life, especially in the area of spray paint, such as interstellar speed and flying skateboard, a little bit of scraping or something, a spray will look new!

Of course, you have to choose the right color first, otherwise if you spray it wrong, you will have to respray it as a whole.

However, the bottle in Cao Ye's hand is black......

"Haha...... This time, Zhao Tingkai's guy has to find a place to cry, and it costs a lot of money to repaint a flying car!" Li Heng said with a fluttering eyebrow.

Starspeed is not really able to fly in the stars, as for the name, it is completely an advertising method of the original inventor.

"Let's go, let's talk as we go, I still have to rush to Brother Biao to get the goods!" Cao Ye urged.

"Uh...... I said why are you in such a hurry, understand!"

Immediately, the two left the school shoulder to shoulder.

When he was halfway down, Li Heng took out two small tickets from his arms with a smug face, and shook them in front of Cao Ye's eyes.

"One-time consumption voucher for Jack's cafeteria!" Cao Ye snatched the meal roll, his eyes green.

"Sad, it's really someone who hasn't eaten meat in his life, and it makes you excited. Li Heng looked disdainful.

"You think about it as a labor-manager!" Cao Ye's two eyes stared directly at the big beast leg pattern on the meal roll, and his saliva almost didn't come out, meat!

For a bite of meat, he dared to blow up the school!

"Okay, I've got the meal rolls, it depends on when your illness will be cured, didn't you say just a few days?"

"I'll put this meal roll here first. Cao Ye put away the two meal rolls very preciously, buffet, what does this mean? It means that he can eat meat until he wants to vomit!

"Breath!" Li Heng looked at his little actions, and couldn't help but be speechless for a while, he had a lot of reason to believe that this guy might be able to do anything undisciplined for a bite of meat.

"Hehe...... " Cao Ye grinned, not caring about his contempt at all, "Well, it should be soon, my dad said that there is still one last course of treatment, and after that, the buddies can eat meat to their heart's content, damn, all the food that has been missed in the eighteen years will have to be made up for by then!"

"Anyway, what kind of disease does your kid have? You can't eat meat, and you can't go into martial arts training?" Suddenly thinking of something, Li Heng asked again, this question he had asked countless times from elementary school to now, but he had never received a positive answer.

"I really want to know?"

"Of course!" Li Heng looked curious.

"Listen, it's a very rare disease, and it's a very obscure name. ”

"Oh, I'm listening!"

"The medical jargon is called, Ji Ji Xiao Mu Heng Li. ”

"What's that?" Li Heng looked confused.

"Okay, I'm going to catch up with maglev, you can experience it yourself. ”

After that, Cao Ye turned the road at the intersection in front of him, his family lived in District 19 of Jiangnan Base City, and Li Heng's family lived in District 21, dozens of kilometers apart, and there was only a short section on the same road.

"What the hell is this?, why have you never heard of it before?" Li Heng looked at his back, and said in his mouth: "Ji Ji Xiao Mu Heng Li ...... Oh, that's not right!"

Suddenly signaling something, he subconsciously reversed these words......

"Damn, Cao Ye, you bastard, dare to fool me!"
