The decline of tactics? The professional talents at the beginning are both full!

Sitting on the sofa in the exclusive room, Xu Bai opened the personal information panel and found the list of secondary skills.

Sure enough, in the sub-skill list, next to the original skill tree of "Basic Array Formation", there was another skill tree.

The "Basic Array Technique" tree has not been lit yet, and there are gray skill trees everywhere.

The main trunk and some branches of the new skill tree have been lit up, while the higher places are still covered in gray and cannot be seen clearly.

That is the skill tree of "Basics·Secret Texture".

The backbone of the skill tree represents arcane science, while the branches represent biology, materials science, engraving methods, mechanism manufacturing, etc.

As well as some items that come with it that can be crafted immediately.

Currently, the content of this new skill tree is lit as follows:

The first level - "Ordinary secret pattern engraving lv.1"

"Ordinary secret pattern engraving lv.1" (Secret patterns can be engraved on any inanimate carrier. After consuming body energy, the secret patterns can be activated, allowing the carrier to obtain corresponding characteristics."

The second level - "Metal Secret Pattern lv.1" (not unlocked, unlocking requires the first level to reach lv.10.)

The third level - "Biological secret pattern engraving lv.1" (not unlocked, unlocking requires the second level to reach lv.10)

Fourth level:? ? ?

........

(The following content needs to be unlocked to view the third level)

........

Today, Xu Bai's secret knowledge is divided into three levels, and each level needs to be independently upgraded before the next level can be unlocked.

For the first and third levels, you can understand their abilities just by looking at their names.

Xu Bai tried to check the information on the second level of "Secret Pattern of Fusion" and found that although it was not unlocked, he could still check the information on this ability in advance.

Fusion of Secret Patterns: Can be used to make Secret Pattern Bombs. Each time you make a Secret Pattern Bomb, you need 1 molten stone, 5 filamentary energy conduction devices, 1 spherical metal shell, and 100 mana points.

"Explosive abilities."

Xu Bai pondered.

not bad.

Now he has only mastered the ordinary secret pattern engraving lv.1, but has not learned the corresponding secret pattern. If he wants to obtain other abilities, he needs to unlock the prerequisites.

Xu Bai began to study the secret pattern inscription and tried to improve it.

"Tip: Yes/No to upgrade the ordinary dense engraving to lv.1. Each level requires an origin coin and proficiency."

"Current proficiency: 0/10"

The skill branch of Secret Pattern Science does not seem to be upgraded in the skill upgrade cabin.

There is no need for additional crystal core stones. You only need to consume origin coins and gain proficiency at the same time to upgrade directly.

But Xu Bai now doesn't know how to obtain proficiency.

Xu Bai's heart sank. Could it be that he had learned a useless skill?

When he tried to improve the ordinary dense engraving, the Origin Coin was consumed directly. A gray stone appeared in front of Xu Bai, with a sharp carving knife beside him.

Immediately afterwards, a light curtain appeared in front of his eyes.

Displayed on the light screen were many secret symbols that he had never seen before.

There are 150 of them.

These symbols have no meaning and are simply for practice.

"Tip: Please engrave the basic practice secret pattern within 10 minutes. After completion, you will gain 1 point of proficiency."

Xu Bai was overjoyed. It seemed that this was not a useless skill.

What he had previously learned was only the basic knowledge of secret patterns.

Now, it’s time to start the actual operation.

Just like the anatomy class in the biology department in college.

After all, the content in the book is just patterns and analysis. If you really want to learn it well, you still need experimental animals to practice it.

........

After checking the prompts, Xu Bai knew that the Court of Origin would not set the upgrade price of a waste skill so high that it would require Origin Coins.

Xu Bai picked up the dusty stone with his left hand and held the carving knife with his right hand.

Start copying the secret symbols on the light screen in front of you.

The sharp carving knife touched the surface of the stone, and Xu Bai used a little force in his hand.

There was only a "click" sound, and the carving knife pierced the stone directly.

The stone cracked in half fell to the floor of the exclusive room with a crisp sound.

Xu Bai's face was covered with black lines.

He just used 10% of his strength, but who knew that the texture of this stone would be so fragile.

With the stone, the reminder of the Garden of Origin appeared again.

"Tip: Acquisition of proficiency failed, please try again."

The prompt disappeared, and a new gray stone reappeared in front of Xu Bai.

"Tip: Please engrave the basic practice secret pattern within 10 minutes. After completion, you will gain 1 point of proficiency."

Xu Bai's origin coins were not consumed again. It seemed that as long as Xu Bai did not complete it, this exercise would not end.

It’s just a matter of how many times it’s reopened.

........

Think of this.

Xu Bai picked up the gray stone again, carefully controlled the carving knife in his hand, and slowly carved the first symbol against the secret pattern of practice displayed on the light screen in front of him.

"Click~~~Click~~~"

Amidst a subtle "click" sound, many stone chips splashed up, and a strange symbol gradually took shape.

The carving knife moved slowly, two minutes later.

The first secret symbol is carved on the gray stone. Although it is extremely ugly, at least the general shape can be seen.

And on Xu Bai's forehead.

Before I knew it, fine beads of sweat had already appeared.

........

The carving knife points to the gray stone surface again.

The second, the third, the fourth, the fifth...

The carving knife in Xu Bai's hand kept twisting and carving secret symbols on the surface of the gray stone.

Just when the sixth secret pattern symbol had just been engraved halfway.

The reminder from the Garden of Origin woke up Xu Bai who was immersed in the inscription.

"Tip: The time has expired and no proficiency has been gained yet."

Immediately afterwards, the surface of the gray stone in Xu Bai's hand flashed with luster, and the gray stone that had been engraved with several secret patterns returned to its original appearance.

Xu Bai was surprised.

After checking the prompt, Xu Bai realized belatedly that the time had already expired.

Try again to start engraving.

This time.

Ten minutes passed, and Xu Bai successfully carved seven secret patterns on it.

"It's not even close."

Looking at the gray stone in his hand that had returned to its original state again, Xu Bai felt a little irritated at the thought of having to engrave a hundred and fifty secret patterns.

The third time begins.

Xu Bai carved seven and a half secret patterns.

the fourth time.

nine.

The task was still very heavy, and Xu Bai's irritability continued to increase.

Xu Bai is not like a saint, who has no emotions and six desires, and is as plain as water at all times.

Although he now has extraordinary abilities.

But on the level of life.

Xu Bai is still alone.

A living person with joys and sorrows.

Xu Bai also noticed his irritability, which was normal, after all, the task was so heavy.

After calming down, Xu Bai has a very strong ability to manage emotions.

He doesn't get agitated or irritable for no reason.

Perhaps influenced by his emotions, Xu Bai only carved eight inscriptions on his fifth try.
