Da, da, da.

The sound of footsteps echoed in the cramped dark corridor.

The voice control on the wall has long since fallen into disrepair.

Only the thick stained glass in the hallway could barely let in a little light.

Li Changan took the two little guys, Xiao Fan and Xiao Douding, to the old town of Yangcheng again, the old residence of his teacher, Professor Yan Fuchun.

Bang!

Suddenly, above the hallway, there was a heavy sound of something falling.

Li Changan couldn't help but speed up his pace.

When I went upstairs, I found that it was a middle-aged man who had fallen down the stairs.

"Are you alright?"

Li Changan stepped forward and asked, wanting to help him.

Then the man raised his hand.

"No, it's fine."

The voice was full of energy, and the state of the performance was very healthy, the man quickly stood up and said with a smile: "It's just that my foot is slipping." ”

Looking at this posture, there should be no problem, Li Changan nodded, and didn't care.

However, when the man stood up and turned his head to look at him, Li Changan couldn't help but "chuckle" in his heart.

The bloodshot eyes were full of exhaustion, and the dark circles under his eyes made Li Changan almost think that he had seen a "ghost".

"Hehe, I just got off work and I'm in a hurry to go home for dinner." The middle-aged man explained with a smile.

"But thank you."

After speaking, he strode steadily and quickly upstairs, still taking two steps at once.

Seeing this, Li Changan shook his head and couldn't help but laugh at himself secretly.

"It really left a shadow on that corpse in my heart, and everyone looks like a 'ghost'."

But this man is really weird.

Obviously, he seems to be very healthy and powerful, and his steps are extremely steady, but how can he look at his face as if he hasn't slept for five or six days?

And......

"Just got off work?"

It's almost noon.

Is it going to work in the morning and coming back for dinner at noon, or is it ....... Have been working since yesterday until now?

With doubts, Li Changan turned on the "Soul Vision" and glanced at the man who was walking upstairs quickly.

When he saw it, he felt even more wrong.

How can a healthy adult man's "soul" be so thin?

If you work all night and are sluggish, your body should also be sluggish.

But if you go to work in the morning and go home for dinner at noon, your spirit is not right.

Li Changan frowned, reached into his pocket, and adjusted his ability.

"Little Bean, psychic."

"Squeak~~"

The little guy hiding in the pocket of his coat didn't even poke his head out, and the perception of "psychic" spread.

A moment later.

"Squeak ~~" (木有. ）

"Meow?" (Looking for what?) Got a treasure? ）

Xiao Fantasy couldn't help but ask.

Li Changan shook his head.

"Forget it, it's none of our business."

Let's walk back to the second floor.

...

Came to Professor Yan Fuchun's old house again.

At the beginning here, Ran Swordfish and the mysterious black-robed man had a fierce fight, causing the entire house to be dilapidated and the contents of the house to become a mess.

But when he came in again this time, Li Changan found that the damaged walls and everything inside had been repaired, the tables and chairs had all been repaired, and even the most damaged study had been restored.

It's just that the traces of the house restoration are obvious.

And although the books in the study are neatly arranged, they don't have the neat appearance of the previous categories.

I stood in front of those bookshelves for a long time.

In his mind, he recalled how he used to study with Professor Yan Fuchun.

It's only been a few days, and it's already a matter of fact.

"It's a pity that the teacher has no children."

He said with a sigh and a pity.

Li Changan began to rearrange the classified books while searching for the ones he needed.

"There you go. "The Law of Evolution and Self-Evolution of Ancient Texts", "Complete Analysis of Ancient Texts of Spiritual Materials", "Records of Ancient Texts of Yan Fuchun", ......"

For Li Changan now, this is tantamount to entering a treasure trove, full of a treasure trove of knowledge.

When I see every book, I can't wait to open it.

Although Professor Yan Fuchun's collection of books is not as large as that in the library of the Quiet Society, Professor Yan Fuchun's books here are very targeted, and most of them are books on the study of ancient characters.

Moreover, there are many books with Professor Yan Fuchun's essay records, which greatly reduces the difficulty of reading.

After all, Professor Yan Fuchun is a noted paleographer, an expert focusing on the study of ancient languages, and has published a lot of works, which can be regarded as one of the authorities in the industry.

"Huh?"

Li Changan found Professor Benyan Fuchun's essay, and he was just flipping through it, but he saw something that interested him.

"The original ancient script evolved from another script that had already formed a system, which we called 'Buqi script', and based on my years of understanding of characters and object glyphs, combined with the writing method of the first ancient script, I was surprised to find that the appearance of the formed script was reversed....... According to the way the text is written, whether it is the angle, the pen, or the finish, it is extremely similar to us humans! I would even think that the formed text was originally made by human hands.

I don't have enough evidence, but I get excited about such a discovery. Maybe I can come up with something like "Fu Si ....."

Li Changan rubbed his chin gently.

"Similar to humans? Is it an early human, similar to the Atlantean from the previous life? Or is it that there are highly intelligent beings of the humanoid race that exist in the early morning? Is 'Buqiwen' what that kind of writing is called.....

As he continued to scroll down, Li Changan frowned.

"Gone?"

The subsequent essays show obvious signs of the paper being torn off.

Writing only a beginning is not a teacher's practice.

Put away the essay.

Let's see if we can find the scattered papers in the other books.

"Yan family tree?"

Soon Li Changan found something that surprised him a little.

The genealogy of the teacher, Professor Yan Fuchun, has never heard the teacher say anything about his family.

There is a family tree, which means that Professor Yan Fuchun's original family should not be small.

It's just that I don't know if it disappeared into the long river of history, or if Professor Yan Fuchun left the family.

Li Changan was unable to get anyone's name from it, because the entire family tree was blackened by ink.

"I almost forgot what the point of being here was."

Li Changan, who reacted, hurriedly put down these books that he was interested in, and when the time came, he could take them back and read them slowly, whether he came this time to translate the "Shadow Yan" skills, and at the same time to see if he could use these books to translate the ancient text on the photos.

...

"Whew-"

When leaving the old mansion with a pile of books, Li Changan looked at the list in his hand and nodded contentedly.

[Skill]: Shadow Yan

Attribute: Shadow

[Grade]: Restricted Grade

[Condition]: Must be proficient in the "Phantom" skill, and the proficiency level must reach the third level (B).

[Introduction]: By creating a virtual shadow, we can judge and calculate the good fortune and misfortune in the future.

[Method]: 100ml of distilled water, 8 pieces of Chryan petals, 3 drops of tulip juice, 10 grams of Star Stone powder, 10ml of Lingsu bird blood, stir according to the pattern and drink.

"Although it's not a combat skill, it seems to be a little bit of a chicken rib, but it's really a skill that Xiao Fantasy can learn."

Li Changan, who has the ability to adjust the efficiency value of the spirit beast, can see it clearly.

Maybe the efficiency value of a single skill of Xiaofu increases slowly, but if you increase the total number of skills learned, won't the overall efficiency value go up?

For example, the skill "Shadow Escape", which has just been learned, now has an efficiency value of 14 points.

And these 14 points, if you simply increase the three skills it has learned before, the time it will take is much more difficult than improving the proficiency of "Shadow Escape".

Fantasy's total skill efficiency is now 93.

But even if Li Changan spent a lot of "soul" and added all the efficiency values to a skill, he couldn't make this skill show the effect of A-level proficiency.

So he guessed that the minimum standard for A-level proficiency was most likely 100 points!

Then this "Shadow Evolution" skill is particularly important to make up for the last 7 efficiency points.

After this period of training, Li Changan found a very critical point.

Like what.

When Xiao Fantasy's "Dancing Claw" skill is at the C level of proficiency, he adjusts it to reach the B level of proficiency, so Xiao Phantom can gain a lot of insights from the training, and the improvement speed is relatively fast.

And when Xiao Fan's "Dancing Claw" reached the B level of proficiency, even if he still adjusted the value, Xiao Fan's improvement speed was not as exaggerated as before, and the pace was much slower.

This is the "experience" bonus that comes with cross-level training.

And.

"Shadow Yan" is a restricted-level inferior skill, and Li Changan doesn't believe that it is really so chicken.

Limit-level inferior skills, no matter how scummy you are, getting A-level proficiency will be very exaggerated, right?

Class C can be used in actual combat, Class B is relatively rare, how exaggerated is Class A?

If it encounters actual combat in the future, Xiao Phantom can use A-level proficiency skills, then it will definitely be a qualitative leap in the strength it can show.

"Before going to collect materials, go to Granny Gu and ask, if she has it, it should be cheaper. If it's not enough, go to the spiritual material market to make up, and by the way, give the two little ones some food. I just don't know if I have enough money. ”

When it came time to spend money, Li Changan felt that the money was really unspent.

Take out the lighter you have prepared in advance and burn the paper out.
