Even with only one drop of blood, I am still invincible in the world!

Just as he was about to view the details, Su Mubai suddenly remembered something and said:

"Cancel."

"I almost forgot about this."

He opened the attribute panel and looked at his remaining skill points.

"It's a pity that neither Kakus nor Franklin dropped the intermediate skill book."

Su Mubai curled his lips. He originally thought that he could gain some skill points from these two BOSSes.

However, with the 50 points rewarded for the first single-player epic BOSS kill, he now has a total of 62 skill points.

Enough!

If it is used to upgrade [Death Feedback], it can be upgraded to level 6, while [Death Gaze] can only be upgraded to level 1.

It is obviously more cost-effective to use it to upgrade [Summon Shadow Knight].

After upgrading from A-level skills to S-level, the skill points required for upgrading will increase.

If you upgrade first and then upgrade, the skill level can be retained. This is the perfect choice!

[Your profession far exceeds the skill learning requirements. You have learned the new skill "Summon Shadow Knight". ]

Su Mubai was too lazy to check the skill details and directly upgraded this skill to the maximum level in one go.

Like summoning skeletons, this summoning skill can only be upgraded to level 9, using 18 skill points.

[Cataclysm]!

[Goal: Summon Shadow Knight]!

[Hint: Please choose the promotion grade, first/second/third. ] (Click to view details)

Option 1: Promote to S-level skill [Summon Headless Knight], no consumption.

Option 2: Sublimate to SS-level skill [Summon Abyss Knight], consume 100 million soul coins.

Option 3: Cataclysm to SSS-level skill [Summon Death Knight], consume 100,000 years of life.

Although he was envious of the SS-level Abyss Knight and SSS-level Death Knight, Su Mubai had no choice in the end.

"Promoted to the first level."

Who understands the pain of being able to see but not get, and having to choose to get it for free every time?

[Your A-level skill "Summon Shadow Knight" is promoted to S-level skill "Summon Headless Knight". ]

Before I had time to check the properties of the new skill, an unexpected system prompt sounded.

[Tip: The Headless Knight is a high-level commander type, your summoning space branch is open, and the initial commander space is 1. ]

"Commander type? Open branch? Commander space?"

A short prompt contains a lot of information.

Su Mubai was slightly stunned, then opened his attribute panel and looked at the summoning space column.

I saw that there was another summoning space below the original summoning space, but the last affixes of the two were different.

[Summoning space: 340/1340] (Normal)

[Summoning space: 0/20] (Commander)

"Hmm? Isn't it 1 at the beginning?"

Looking at the newly added commander summoning space, Su Mubai's eyes were full of confusion.

The normal summoning space increased by 1000 because of the entry of [Forgotten's Sorrow].

The commander space is because of...

[Death Recruitment]!

Su Mubai immediately thought of the SS skill attached to this profession.

He immediately checked the equipment and skills that can increase the summoning space.

As expected, with the opening of the summoning space branch, the descriptions of these equipment and skills have also changed a little bit.

The entry of [Summoning Space Expansion] and [Forgotten's Sorrow] has the word "normal".

Only the skill [Death Recruitment] has not changed!

[Death Recruitment]: (SS) Passive skill, no level.

Skill effect:

1. The casting time of summoning skills is reduced by 75%.

2. The cooldown time of summoning skills is reduced by 75%.

3. The attributes of summoned creatures are increased by 100%.

4. The upper limit of the summoning space is increased by 10 times.

It was the fourth skill effect of [Death Recruitment], combined with Su Mubai's professional catastrophe characteristics, that gave him 20 commander summoning spaces!

"It's worthy of being an SS skill."

Finding the reason, Su Mubai checked the newly learned skills.

Commander troops, this name sounds much more powerful than ordinary troops.

[Summon Headless Knight]: (S) Level 9 (0/5), active skill, summon a headless knight to fight for you.

Casting time: 5 seconds, cooldown time 10 minutes, consumes 5000 mana points.

(The headless knight panel is affected by the player's spiritual attribute bonus.)

"I want to see what the difference is between the commander troops."

Su Mubai raised his eyebrows and waved his staff directly.

[Summon Headless Knight]!

[Forgotten's Sorrow] increases the casting speed, plus this is a summoning skill, 5The casting time of 1 second is only 0.28 seconds for Su Mubai.

In the blink of an eye, a light gray portal opened beside Su Mubai.

Frost, who was digesting materials on his shoulder, looked up and then closed his eyes again.

Da, Da, Da...

Two headless knights appeared side by side.

They were wearing heavy black armor, which was covered with traces of erosion by time and scars of battle.

One hand tightly grasped the reins, and the other held a conical knight's spear.

The skeleton warhorse under his crotch was tall and mighty, also wearing heavy armor, with green flames burning on the horse's hooves, and ghost fire flickering in his eyes, exuding a chilling death aura.

Although he was called a headless knight, he wore a metal helmet on his neck.

It was not until the two headless knights took off their helmets lightly and saluted Su Mubai respectfully.

He realized that under their helmets, there were only two strands of beating soul fire, not even a skull.

"This momentum is indeed much stronger than that of ordinary skeletons."

Looking at the mighty and domineering Dual Knight, Su Mubai nodded with satisfaction.

However, he did not rush to check the data of the two, but his mind moved.

[Cataclysm]!

[Target: Dual Knight]!

[Hint: Do you confirm to overwrite the previous effect and re-promote the skill "Summon Shadow Knight". ]

"Cancel."

Getting the same answer as when he wanted to nest the skeleton before, Su Mubai frowned and turned to look at the frost that was digesting with his eyes closed.

They are all summoned creatures, why can frost be promoted for free twice, but skeletons and Dual Knights can't?

Is it because the latter two are summoned by skills?

Or... the creatures summoned by skills are not real creatures?

Thinking of this, Su Mubai had some guesses in his heart.

This can be seen from the panels of the three.

Frost has a life level, but skeletons and Dual Knight do not.

No matter how strong their attributes are, they are just summons.

Just like the Dullahan and Skeleton Legion summoned by Franklin before, the panel shows that they are always summoned creatures, and no experience points will be gained by killing them.

Although he failed to get it for free this time, Su Mubai's understanding of the Wanjie Game has taken a step further.

"How can I upgrade again?"

Su Mubai suddenly noticed that after the skill [Summon Dullahan] was promoted, it could be added again.

After taking a look at the attribute panel of the Dullahan, Su Mubai consumed 5 skill points to upgrade this skill to level 10.

However, the skill level can still be improved!

Comparing the changes after the upgrade, Su Mubai showed an expression of sudden enlightenment and directly added all the remaining skill points to this skill.

Remaining skill points: 4 points.
