Let's start by analyzing the sun

Before long, all the streetlights along the road lit up.

These lamps were fueled by "brown oil," which comes from perennial trees called stone fruit trees.

When this tree reaches twelve years of age, it bears stone fruits, whose skin is as hard as rock and contains a viscous, high-calorie oil called "stone fruit gum."

This substance can be refined to obtain brown oil; the refining residue, mixed with wood chips, can be pressed into honeycomb briquettes; brown oil mixed with resin can also be made into candles.

In short, it has many uses.

Cheng Han felt that stone fruit gum was a bit like petroleum in his previous life.

The difference is that the latter is extracted from underground, while the former grows on trees.

Ten minutes later.

Cheng Han rode his bicycle to the main gate of Shanyi Ward.

The so-called "Shanyi Ward" is a welfare community built by the government, where civilians with low incomes live, totaling more than one hundred and sixty households, and there are not many orphans like him.

Cheng Han jumped off his bicycle and pushed it towards the gate.

"Woof! Woof!"

Loud barks came from the gate.

Two imposing large dogs, reaching the waist of an adult male, trotted over from the left and right.

They were spirit mastiffs, with intelligence comparable to a fifteen-year-old teenager, and could understand human language.

Spirit mastiffs are working dogs with "official status," belonging to the Patrol Department, which arranges several spirit mastiffs for each community to serve as security in residential areas.

Cheng Han immediately shouted, "Peach, Plum, it's me!"

The two spirit mastiffs wagged their tails a few times in a friendly manner.

The spirit mastiff named "Peach" walked around Cheng Han, and also put its nose close to his schoolbag, sniffing carefully several times.

This was a routine check.

There are many harmful items related to alien gods in this world, and one of the spirit mastiffs' duties is to identify these things and prevent them from being brought into the community.

"Woof!"

Peach barked once, and its head swung towards the gate, as if to say: Go in.

Such behavior can be described as having become an elf.

Cheng Han waved to them and passed through the community gate.

"Woof! Woof!"

The two spirit mastiffs responded once each, watching him enter the community.

Cheng Han's small apartment has a layout of one bedroom, one living room, one kitchen, and one bathroom, with a total area of more than thirty square meters.

Before he turns sixteen, he does not need to pay a single copper coin in rent, and can also receive twenty pounds of rice, ten pounds of flour, and four hundred and fifty copper coins each month.

In contrast, in his previous life, his broken single room was only ten square meters, but the rent was as high as 1,500 yuan, which took up one-third of his salary, and after deducting expenses such as food, transportation, and clothing, there was very little left over each month.

Although this world does not have various household appliances and the convenience of life is much worse, the pressure of life is far less than in his previous life.

Cheng Han put down his schoolbag and started to cook dinner.

First, pour a little brown oil into the stove to ignite it, then put in a piece of honeycomb briquette, and soon, a hot flame emerged.

Simply rinse the rice, put it on the stove, grab a handful of white umbrella mushrooms and wash them twice, and stir-fry them with a few pieces of salted meat in an iron pot, and a dinner is ready.

Cheng Han tasted a white umbrella mushroom and nodded slightly: "The taste is not bad!"

White umbrella mushrooms contain a variety of amino acids, and the oil completely stimulates the umami taste, and the deliciousness is by no means inferior to truffles in his previous life.

He deeply felt that the development and utilization of plants by humans in this world is far higher than in another time and space.

The stone fruit tree is a typical example, and fungi are also an example.

Since crossing over, Cheng Han has seen at least five hundred kinds of mushrooms in the vegetable market.

After eating dinner, he entered the bedroom, lay on the bed, and his breathing quickly became long.

The meditation class at school taught a technique called the "Fushan Breathing Method." According to Qiu Yuan, if you are proficient in this breathing method, you can enter a state of deep sleep in three minutes.

This method requires extremely high talent, and only one person in the class barely got started, and only one or two out of ten attempts can quickly enter deep sleep.

Even within the entire school, the number of people who have gotten started does not exceed fifteen.

Of course, the predecessor was not among them.

After Cheng Han crossed over, he had a whim one time and used his skill to deduce the breathing method, and actually got feedback - if a certain detail is adjusted, it will help to master the breathing method.

He tried it and found that his sleep state had improved slightly.

Surprised, Cheng Han decided to comprehensively improve the breathing method. After half a year of deduction, he finally obtained a brand new breathing method - the Cheng Breathing Method.

More importantly, this is a method that perfectly fits him.

Not only is it always effective, but the effect is also surprisingly good.

It only takes two minutes to enter a state of deep sleep, which is much stronger than the Fushan Breathing Method.

An hour later.

Cheng Han woke up.

At this time, he felt refreshed, and there was no dizziness in his head.

Checking the attributes, he saw that the mental value reached 7.2/13.2.

Compared to before, the mental value had recovered a full 6.6 points.

This is the benefit of deep sleep.

Cheng Han imagined the image of the black cat and silently said: "Using the black cat I encountered earlier as a clue, deduce its encounters in the next few days."

A cool feeling immediately rose on his scalp.

But no message was obtained.

The deduction failed.

The mental value decreased by 0.3 points.

Cheng Han took a few deep breaths and silently said for the second time: "Deduce."

The cool feeling reappeared.

But there was still no feedback.

It failed again.

This is actually a normal phenomenon.

Based on past experience, the failure rate of using the Omniscient Eye is almost 85%, and success is a minority.

Cheng Han tried five times in a row, until the sixth deduction, he finally got feedback.

His eyes blurred, and a somewhat blurry illusory lens appeared:

The black cat jumped down from the wall, landed lightly on the ground, it screeched sharply, and ran towards the distance.

A second later, a sudden change occurred.

A dark shadow like ink suddenly appeared on the ground, and a black ghost claw flashed out from it, quickly grabbing towards the black cat.

The black cat seemed to be aware of something, and at the critical moment, it jumped up high.

The ghost claw immediately changed direction and touched the black cat's body like lightning, and then turned into a wisp of blue smoke and disappeared.

An unbelievable thing happened.

The black cat's body seemed to turn into a leaking balloon, and it quickly瘪了下来.

"Pa!"

A complete cat skin fell from the air and landed on the ground with a soft sound.

Its flesh and blood disappeared strangely.

The lens froze for a moment, and then disappeared.

A message flashed by: "Proficiency +4, current proficiency is 20/1000, mental value is 2.4/13.2."

Cheng Han only felt creepy: "My previous hunch was right, there is indeed a problem with the black cat, shouldn't the shadow and ghost claw be the power of an alien god?"

He never expected that an accidental encounter on the way home would involve a terrifying alien god.

Cheng Han calmed down and began to analyze: "In the illusory lens, it is drizzling, which means that the ghost hand will appear on rainy days.

"Judging from the black cat's actions, it probably encountered something terrible inside the wall, so it fled in panic, but it failed to escape its doom."

He couldn't sit still: "There is a textile factory inside the wall, I'm afraid something big is going to happen there."

The ghost claw can instantly suck a black cat dry, so killing people is naturally not difficult, and the factory is a place where people are densely populated. If something really happens, many people will die.

Cheng Han used the Omniscient Eye again: "Deduce when it will rain."

The result came out quickly - there will be a drizzle on the morning of three days later.

This also means that the disaster will happen three days later.

Cheng Han pondered for a long time and made a decision: "Although I don't have the ability to prevent the disaster at the moment, I can secretly call the police, right?

"How about this, first find detailed evidence, and then find a way to notify the authorities.

"The black cat is the victim in the prophecy, and its fate is closely related to the ghost hand. It is naturally the best related item, which can greatly increase the success rate and deduce more information.

"I'll take a day off tomorrow, try to catch the black cat back, and then use the Omniscient Eye to do further deductions."
