The last class in the afternoon is usually a self-study class for students to write homework.
By this time the sky had darkened quite a bit.
Several gray crystal lamps in the classroom all lit up.
Cheng Han squinted at the elegant gray crystal lamp, thoughts flying in his mind.
The so-called "grey crystal lamp" is a lighting appliance that relies on "grey crystal" for energy. Gray crystal is a special crystal that contains a small amount of source energy.
In addition, the crystal-energy cars running on the road and the various machines running in the factory are also driven by gray crystals.
Cheng Han gave this type 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 government hall of Qinglin City gives special treatment to the school and bears the lighting costs of the school, so that the students can enjoy bright gray crystal lamps for free.
By the way, there is no electricity at all in this world.
There is no static electricity in life, and there has never been lightning or thunder in the sky.
Cheng Han once tried to make a hand-operated generator, but unfortunately he couldn't find even a magnetic item, and people around him didn't know what magnetism was.
At this moment, Qian Qingqing was sitting next to him, peeking at his profile from time to time.
Cheng Han noticed his deskmate's gaze, turned around and asked, "Why do you always look at me?"
Qian Qingqing's tone was a little erratic: "I feel more and more that you are completely different from the other boys in the class."
Cheng Han blinked: "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', saying that the gods were the source of all disasters.
"But you said that human desire is the fundamental cause. Even if there are no alien gods, as long as humans still have desires such as greed, disasters will always be inevitable in the world.
"I didn't believe it at the time. When I went home and had dinner yesterday, I talked about what you said with my dad. He thought what you said was right and said that your knowledge surpassed that of many adults."
Cheng Han smiled and said nothing more.
Where could the supernatural gods exist on Blue Star in my previous life? But from ancient times to the present, wars have never stopped, with countless dead and countless people displaced.
He truly felt that human beings' endless desires were the greatest disaster.
"Dingling~"
The bell for the end of get out of class rang.
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 gave a sweet smile: "See you tomorrow!"
Wen Jie, who was sitting in the back row, felt 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 something out of reach.
Every time the young man said "see you tomorrow" to Qian Qingqing, she always ignored him, as if she didn't hear him at all.

Cheng Han walked out of the teaching building, put his right hand in his trouser pocket, held a silver coin, and said silently: "Deduce where you can find money."
This is exactly how he usually "earns" living expenses.
According to experience, if you deduce it directly, you can succeed five times out of ten.
And if you hold a coin, you can get useful information seven times.
Cheng Han calls this phenomenon "correlation", that is, when deducing information, if you hold related items, you can greatly increase the success rate.
Soon, he saw an illusory picture:
There is a coin buried in the shallow soil under a bush. Perhaps because the skill level is not high, the picture is a bit blurry and it is difficult to distinguish the type of coin.
The illusion changed several times, indicating a rough route.
The mental value was consumed again by 0.5 points, leaving only 0.6 points, but the proficiency level still did not increase.
Cheng Han felt slightly dizzy.
This is the result of the mental value dropping to a lower level.
Cheng Han muttered in a low voice: "Dongtai Road, we need to take a detour."
At this time, the school gate was quite busy. 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 very much like cars from the 1930s. These are crystal energy vehicles in this world. They sell for more than twenty gold coins, and only rich people can afford them.
Qian Qingqing's family bought one, and her father drove the little girl to and from school every day.
On the other side, there is a group of riding beasts that are nearly 2.5 meters tall. Their bodies are covered with thick gray feathers and they make "arrogant" sounds from time to time.
Any Blue Star person who sees them will definitely blurt out—dinosaurs.
Because the appearance of these riding beasts really resembles Blue Star's prehistoric Fireraptor.
They are called "feathered beasts", their function is equivalent to horses, and the price is no less than eight gold coins. Most families with better economic conditions will buy a feathered beast as a transportation mount.
The crystal energy vehicle is a product of industrial civilization, while the feathered beast is full of a wild atmosphere, but the two are mixed together.
Cheng Han pushed an old bicycle and thought to himself: "Only those who have traveled through time can see this magical scene."
The bicycle is one of the belongings left by my predecessor. It is at least ten years old. It makes a lot of creaking noises when I ride it, as if it might fall apart at any time.
My predecessor had planned to carry out a major renovation, but was short of money and was unable to take action.
After Cheng Han traveled through time, he repeatedly used the "money-picking technique". In the first month, he picked up four silver coins, purchased a large number of parts, replaced the severely aged parts, and repainted them to restore them to 80% new condition.
My predecessor’s long-cherished wish came true so easily.
A quarter of an hour later.
Cheng Han rode his bicycle and arrived at Dongtai Road.
This is a factory area. There are not many people on the road at this time. The factory buildings on both sides are all brightly lit.
Factories in this world generally implement the "889" working system, that is, starting work at 8 a.m. and getting off work at 8 p.m., with only one day off after nine days of work.
Looking at this scene, he couldn't help but muttered: "I won't go to the factory even if I die from now on."
After walking for several dozen meters, Cheng Han found a large bush near the wall. He compared his memory and nodded: "This should be right here!"
Cheng Han parked his bicycle, walked to the bushes, took out a small shovel, and started digging in the mud.
After more than ten seconds, I heard a "ding" sound and the shovel hit a hard object.
Cheng Han looked happy: "Found it!"
He reached out and dug around in the soil a few times, and sure enough he touched a coin-shaped object. He wiped off the soil on the surface, revealing a silver-white metal texture.
It’s actually a silver coin!
With plug-ins in hand, making money is so easy!
Cheng Han grinned: "The silver coins have been buried, and they were probably lost here a long time ago."
If the owner of the coin can be found, he will take the initiative to return it. If it is lost for too long, the current level of the Omniscient Eye is not high and cannot be traced back, so he can only accept it with a smile.
He tossed the silver coin happily and said, "It's time to go home."
"Meow~"
A cat meow came over.
Cheng Han suddenly turned around and looked at the wall behind him. He saw a black cat squatting on the top of the wall, staring directly at this side with a pair of green eyes.
The two sides looked at each other for a moment, then the black cat jumped lightly into the wall and disappeared.
Cheng Han's heart skipped a beat, and he felt faintly uneasy.
He couldn't help but frowned: "Is this an illusion? Or is this possibly a bad sign?"
Cheng Han pondered for a moment and made a decision: "For safety reasons, it's best to use the Omniscient Eye to deduce. However, the mental value is about to bottom out. Let's go home and restore the mental value first."
