Let's start by analyzing the sun

The black cat, previously perched on a tree branch, quickly stood up, its eyes fixed on the light emanating from the window.

It could vaguely make out an extremely blurry black shadow projected onto the glass surface, constantly changing shape, as if someone was moving inside.

After a few breaths, the light brightened slightly.

A black shadow, resembling a snake, abruptly appeared on the glass.

The black cat's eyes widened immediately.

It recalled a statement Cheng Han had made: "The school has several botanical gardens, yet the mastermind specifically targeted the delicate silk vines, he is likely researching the vines."

The black cat leaned its head forward slightly, its expression more focused.

Could this snake-like shadow be a vine?

It felt that the possibility was extremely high!

After a while, the black cat observed a new change.

The figure walked back and forth in the room, and who knows what he did, but some patches bulged on the surface of the shadow, expanding rapidly like inflating balloons.

The shadow quickly became unrecognizable, and its shape no longer resembled a snake.

The black cat was a little confused.

Could it be that it guessed wrong earlier, and this wasn't a vine?

The next moment.

The black cat suddenly woke up.

Leaves!

The vine grew leaves!

A hint of surprise appeared in the black cat's eyes.

So the other party can make the vine grow quickly.

Another half hour passed.

The light completely disappeared, and the window was once again swallowed by darkness.

The black cat waited patiently for a while, but there was still no movement in the house.

It understood that the other party should have gone to bed.

The black cat stood up and decided to go home to report the situation to its master.

The master said that tonight was just the first reconnaissance, and don't risk entering the house. After figuring out the other party's background, make the next plan.

This is called "not fighting unprepared battles".

It carefully climbed down from the tree and quickly walked away.

*

Two o'clock in the morning.

Cheng Han used the Eye of Omniscience to analyze the sun again.

The completeness of the True Flame Remnant Mark increased to 1.88%, and the skill proficiency increased to 112/1000.

"Snap!"

Cheng Han snapped his fingers, and a wisp of orange flame appeared at his fingertip.

Compared to before, the flame color was much deeper.

This means the temperature has increased.

The power is naturally stronger.

An idea popped into Cheng Han's head: "Right, I can measure the flame temperature."

Although there is no thermometer, it doesn't matter.

As an engineering student, how could he be stumped by this small problem?

Cheng Han found pliers, clamped an iron nail, and placed it above the flame. The iron nail turned dark red at a speed visible to the naked eye.

And the temperature of dark red iron is between 600 degrees and 700 degrees.

Cheng Han grinned slightly: "The iron nail turns red so quickly, the heating rate is abnormally fast, it is indeed an extraordinary flame!"

He extinguished the flame and thought: "Extraordinary abilities that ordinary people can only dream of, but I use them to make fire and cook every day, which is really not presentable.

"There are alien gods in this world, and alien god believers are causing trouble everywhere. I must explore the practical combat skills of extraordinary flames to have a certain ability to protect myself."

Cheng Han immediately thought of the most common game skill - Fireball.

He smiled: "In the future, when I encounter an enemy, I will first smash a fireball at them, let them feel the enthusiasm of this young master, just thinking about it makes me feel very happy."

However, the ideal is very full, and the reality is very skinny.

Cheng Han's face turned red before he could condense a sesame-sized fireball.

Well, perhaps it is more appropriate to call it a light spot.

He tried several times in a row, but the "ultra-mini fireball" only flew more than two meters before losing control and collapsing into a ball of flame.

Cheng Han shook his head helplessly: "Then I can only take the close combat route."

He struck a rather chuunibyou pose and shouted: "Eat my Dragon Subduing Eighteen Palms!"

Just then.

A small wooden board in the corner of the roof was suddenly pushed open, and a dark cat's head poked out from inside.

This is the sheriff's private door.

The black cat happened to be back at this time.

"Meow~"

It called out suspiciously, as if saying: What are you doing?

One person and one cat looked at each other, and the air solidified.

The atmosphere was a little awkward.

Cheng Han's psychological quality was excellent, he waved his right palm forward without changing his face, and shouted at the same time: "Dragon has regrets!"

At the same time, he activated the True Flame Remnant Mark.

Along with the waving of his palm, a bright flame spewed out of thin air, instantly forming a dazzling arc of flame, and then dissipated into the air.

When the black cat saw this scene, its pair of cat eyes widened again.

Just now it thought the master was a bit silly, but now it thinks he is too powerful.

Cheng Han asked with a smile: "Is it handsome?"

This move is not only handsome, but also has no weak lethality. If an ordinary person is hit by the flame, they will definitely be burned to pieces, and there is a high probability that they can handle the funeral.

"Meow~"

The black cat's cry was full of disbelief.

Cheng Han beckoned to the sheriff: "Come down quickly."

The black cat jumped up, its two front legs stepped on the opposite wall, and then using the reaction force, jumped back, and finally landed on the ground extremely smoothly.

Objectively speaking, it is also very handsome to jump down so cleanly from a place nearly three meters high.

Cheng Han asked: "Is there a result?"

The black cat nodded: "Meow!"

Cheng Han stretched out a finger and ordered: "Concentrate your mind and recall the information you think is most important."

After the Spirit Control Remnant Mark is completed, it can not only transmit information to the black cat, but also directly extract information from its mind. This is two-way communication.

The black cat jumped on the sofa and called out: "Meow~"

It meant: Ready.

Cheng Han took a light breath, activated the remnant mark with his mind, and pointed at the sheriff's forehead.

In an instant, he received the black cat's memory.

Starting from the appearance of the black shadow from the window of that house, until the window was completely dark, all the details were included without any omissions.

Cheng Han praised fiercely: "You did a great job!"

The black cat wagged its tail happily.

Cheng Han rubbed the cat's head a few times and said, "Your judgment is correct, the black shadow projected on the glass is indeed a vine."

He sighed: "The delicate silk vines in the school's botanical garden have turned into grass dogs, and vines have also appeared in Tan Zicheng's home. This is by no means a coincidence. It seems that this guy is indeed the mastermind."

Originally he was just suspicious and could not be completely sure.

Now he has conclusive evidence.

The black cat looked up at its master and meowed several times.

It was asking: What else do you need me to do?

Cheng Han pondered for a moment and ordered: "Help me catch a few birds tomorrow. I need small birds, preferably no more than a palm."

The black cat was puzzled: "Meow~"

Yesterday the master clearly said not to catch birds, why did he change his mind again?
