The last class in the afternoon is usually a self-study class dedicated to students writing homework.

By this time it was getting a lot darker.

The few gray crystal lamps in the classroom were all lit up.

Cheng Han squinted at the elegantly shaped gray crystal lamp, and thoughts flew in his mind.

The so-called "gray crystal lamp" is a lighting appliance that relies on "gray crystal" for energy, and gray crystal is a special crystal containing a small amount of source energy.

In addition, the crystal energy vehicles galloping on the road, and the various machines running in the factory, are also driven by gray crystals.

Cheng Han gave this kind of item a name - Jingneng Technology.

However, although Gray Crystal is easy to use, it is relatively expensive, and only wealthy families can afford it.

The council hall in Qinglin City gives special treatment to the school and bears the cost of the school's lighting, so that students can enjoy the bright gray crystal lanterns for free.

By the way, there is no electricity in this world at all.

There is no static electricity in life, and there has never been lightning or thunder in the sky.

Cheng Han once tried to build a hand-cranked generator, but unfortunately he couldn't find a single magnetic object, and the people around him didn't know what magnetism was.

At this moment, Qian Qingqing was sitting next to him, peeking at his side face from time to time.

Cheng Han noticed the gaze of his fellow tablemates, turned his head and asked, "Why do you keep looking at me?" ”

Qian Qingqing's tone was a little fluctuating: "I feel more and more that you are completely different from the other boys in the class. ”

Cheng Han blinked his eyes: "What's the difference?" ”

Qian Qingqing gave an example: "In yesterday's history class, the teacher talked about several terrible disasters related to the 'three great gods', and said that the other gods are the source of all disasters.

"But you say that human desires are the root cause, and even if there are no other gods, as long as human beings still have greed and other desires, there will always be disasters in the world.

"I didn't believe it at the time, but when I came home for dinner yesterday, I talked to my dad about what you said, and he thought you were right, and said that your knowledge is beyond that of many adults."

Cheng Han smiled and didn't say anything more.

Blue Star in the previous life, where is the existence of alien gods? However, since ancient times, the war has not ended, and countless people have been killed and countless people have been displaced.

He truly felt that the infinite desire of human beings was the greatest disaster.

"Jingle Bell~"

The bell rang for the end of class.

The classroom immediately became lively.

Cheng Han quickly packed up his personal belongings and said goodbye to the little girl: "See you tomorrow!" ”

Qian Qingqing sent a sweet smile: "See you tomorrow!" ”

Wen Jie, who was sitting in the back row, was jealous again when he saw this.

For Cheng Han, saying "see you tomorrow" to each other every day is just a trivial matter, but for Wen Jie, it is unattainable.

Every time this young man opened his mouth to say "see you tomorrow" to Qian Qingqing, she always ignored it, as if she hadn't heard it at all.

*

Cheng Han walked out of the teaching building, inserted his right hand into his trouser pocket, held a silver coin, and said silently: "Deduction where you can pick up money." ”

This is exactly how he usually "earns" his living expenses.

As a rule of thumb, if you deduce it directly, you can succeed five times out of ten.

If you hold a coin, you can get useful information seven times.

Cheng Han calls this phenomenon "relevance", that is, when deducing information, if you have related items, you can greatly increase the success rate.

Soon, he saw an illusory picture:

A coin is buried in the shallow dirt beneath a bush, and perhaps due to the low skill level, the picture is a little blurry, making it difficult to distinguish the type of coin.

The illusion changed several times, indicating the approximate route.

The spirit value has been consumed by 0.5 again, leaving only 0.6 points, but the proficiency still does not increase.

Cheng Han felt a slight feeling of dizziness.

This is the result of a drop in mental value to a low level.

Cheng Han muttered in a low voice: "Dongtai Road, you need to take a detour." ”

At this time, the school gate was quite lively, in addition to a large number of students, there were also some parents who came to pick up their children.

There are several four-wheeled vehicles parked on the road, which look like cars from the thirties of the previous life, this is the crystal energy car of this world, which sells for more than twenty gold coins, and only the rich can afford it.

Qian Qingqing's family bought one, and the little girl was picked up and dropped off by her father every day when she went to and from school.

On the other side, there is also a group of riding beasts of nearly two meters and five, their body is covered with thick gray feathers, and they make a "Angang" cry from time to time.

Any Blue Star person, the moment they see them, will definitely blurt out - dinosaurs.

Because the appearance of these riding beasts is really like the prehistoric fire raptor of the Blue Star.

They are called "feathered beasts", which are equivalent to horses, and sell for no less than eight gold coins, and most families with better economic conditions will buy a feathered beast as a substitute mount.

The crystal energy car is a product of industrial civilization, and the feathered beast is full of wild atmosphere, but the two are mixed together.

Cheng Han pushed an old bicycle and muttered, "Only a traverser can see this magical scene." ”

The bicycle is one of the legacy of its predecessor, at least ten years old, and it creaks around as if it could fall apart at any moment.

The predecessor had planned a major renovation, but he was too shy to do so.

In the first month, he picked up four silver coins, purchased a large number of parts, replaced the seriously aged parts, and resprayed the paint to restore it to a new state.

The long-cherished wish of the predecessor for many years was so easily realized.

A quarter of an hour later.

Cheng Han rode a bicycle and arrived at Dongtai Road.

This is the factory area, there are not many people on the road at this time, and the factories on both sides are brightly lit.

Factories in the world generally implement the "889" work system, that is, go to work at 8 o'clock in the morning, leave work at 8 o'clock in the evening, and work for nine days before one day off.

He looked at this scene and couldn't help muttering: "I won't go to the factory if I am killed in the future." ”

After walking for dozens of meters, Cheng Han found a large area of bushes close to the wall, he compared his memory, nodded and said, "It should be here!" ”

Cheng Han parked his bicycle, walked to the bushes, took out a small shovel, and began to dig in the mud.

After more than ten seconds, I only heard a "ding" sound, and the shovel touched a hard object.

Cheng Han's face was overjoyed: "I found it!" ”

He reached out and dug through the dirt a few times, and sure enough, he touched a coin-like object, which wiped the dirt off the surface, revealing a silvery-white metallic texture.

It's actually a silver coin!

With plug-ins in hand, it's that easy to make money!

Cheng Han grinned: "The silver coin has been buried, and it is estimated that it was lost here a long time ago." ”

If the coin can be found by its owner, he will return it voluntarily, and if it has been lost for too long, the current level of the omniscient eye is not high, and it cannot be traced, so he can only laugh at it.

He flicked the silver coin in a cheerful mood: "It's time to go home." ”

"Meow~"

A cat meow came.

Cheng Han turned his head abruptly and looked at the wall behind him, only to see a black cat squatting on the wall, with a pair of green and faint eyes, staring straight at this side.

The two sides looked at each other for a moment, and the black cat jumped lightly into the wall and disappeared.

Cheng Han's heart skipped a heavy beat, and there was a faint hint of unease.

He couldn't help frowning: "Is this an illusion?" Or is this a bad omen? ”

Cheng Han pondered for a moment and muttered: "For the sake of safety, it's best to use the omniscient eye to deduce, but the spirit value is about to bottom out, let's go home and recover the spirit value first." ”

He stepped on his bicycle and sped away.
