Studying Dark Knowledge

After setting down the thick-covered spellbook, Gu Xi turned his gaze to the remaining four wooden doors, where soldiers could learn spells.

[Mana Drain (Soldier Learning): Drains 3 mana from the enemy before the start of battle.]

Researchable derivative skill: Mana Accumulation.

[Mana Accumulation (Researchable at Level 1 Magic Tower, Progress 0%): The mana drained by soldiers can be stored and eventually transformed into Magic Potion that replenishes 100 mana points for the player to use.]

[Blood Loss Curse (Soldier Learning): Cursed enemies automatically lose 3 health points per second.]

Researchable derivative skill: Curse Deepening.

[Curse Deepening (Researchable at Level 1 Magic Tower, Progress 0%): Cursed soldiers automatically lose double their health every second.]

[Slow Spell (Soldier Learned): Reduces enemy movement speed to 50% of their normal speed.]

Researchable derivative skills: Comprehensive Slow.

[Comprehensive Slow (Researchable at Level 1 Magic Tower, 0% Progress): Reduces enemy reaction speed and decreases enemy attack speed.]

[Illusion Spell (Soldier Learns): Creates an illusion that looks exactly like the user. The illusion cannot attack and has 1 health point, but it can perform the same actions as the user.]

Researchable derivative skill: Multiple Illusions.

[Multiple Illusions (Researchable at Level 1 Magic Tower, 0% progress): Releases three illusions around you to draw enemy fire.]

After glancing at the skills that the magic-based soldiers here could learn, he made up his mind.

No matter who comes, everyone will definitely choose Mana Drain at the start.

In addition, Gu Xi also plans to research the derivative skill of Mana Accumulation.

This is a free blue potion. Although it only replenishes 100 mana points at a time, the problem is that Gu Xi's Death Avatar can use it as long as he has mana.

This is equivalent to Gu Xi carrying hundreds of them with him at all times.

As for other spells, it depends on the situation. Those more valuable Magic Unit can learn an Illusion Spell for self-protection.

If it's Skeleton Mage or something similar, just use Slow Spell.

As for the Blood Loss Curse, that's for fighting bosses.

When that time really comes, wouldn't it be better for the Skeleton Mage to use spells instead of the Blood Loss Curse?

"Anthony, do we need manpower to research derivative spells?"

"No need, the Magic Tower can research it on its own right now."

Anthony said confidently.

"Alright, let's study Mana Accumulation first, and then scattering, death and despair, and Multiple Illusions."

Gu Xi pointed out the things he wanted one by one.

Gu Xi had already figured it out. Of the three spells that players and Hero could learn, Wave of Death and Magic Arrow were the highest priority, followed by Flame Trap.

As for passive skills, Gu Xi actually encountered Dark Knowledge once. When he leveled up to level 2, Dark Knowledge was one of the three choices.

However, Gu Xi chose Undead Domination at the time, which was more suitable for necromancer skills.

Now that it's reappeared and available for free, Gu Xi naturally wouldn't miss it.

It's important to know that the curse path in necromancers is equivalent to Dark Knowledge.

In the end, they can even use an ability called "You and the Netherworld Curse" to inflict great damage on all non- Undead Creature present and transform those damaged by this curse into new undead.

This is almost equivalent to a weaker version of the Undead Scourge.

Even if Gu Xi doesn't follow the path of curses, it's still reasonable for him to learn it.

As for the three derivative skills of Dark Knowledge, Gu Xi doesn't care about them for the time being.

After all, his magic contains relatively few curses, and he currently needs to focus his energy on city construction and undead control.

Therefore, it's enough to know about the Dark Knowledge; there's no rush to deal with it.

On the contrary, the derivative techniques of the other spells are quite effective, and it will be a worthwhile investment to start researching them now.

When Anthony heard that there was something to do, he didn't say anything and quickly made the arrangements.

At that moment, Gu Xi pushed open the door to the room, which was decorated with gold trim.

After entering the small door of Dark Knowledge, Gu Xi saw that behind the door was darkness, with many books floating in the darkness, occasionally flying out of the darkness.

Gu Xi hesitated for a moment at the door, but finally stepped inside.

After Gu Xi stepped through the small door, the darkness behind it completely disappeared, and the room became an ordinary study again. Inside the study was a desk, a Soul Crystal that served as a lamp, and a wall of thick black books.

As Gu Xi sat down at his desk, a string of words suddenly popped up in front of him.

Reading ten dark books will raise your Dark Knowledge level to Level 1. Once you have mastered Dark Knowledge, you can further improve your Dark Knowledge level through reading and other means.

Looking at the pop-up message, Gu Xi glanced at the wall full of books and knew he had hit the jackpot this time.

Back then, at the Minggu Bone Wind Academy, he spent countless hours attending classes and memorizing texts, putting in so much effort to build up his Undead Knowledge and Magic Knowledge.

If I read all the books here now, my level of Dark Knowledge will skyrocket.

So Gu Xi didn't delay. He reached out and took down a thick black book. Before he even opened it, he felt a numbness in his fingers, and a black aura flowed from the book into Gu Xi body through his fingers.

"What the hell! This book is cursed or something."

Gu Xi flipped his hand over, channeling his magic power into his palm to force the black aura out.

After that, he ignored all that and began to read the thick black book.

The book contains basic knowledge of the dark side, which is how Gu Xi started learning about the Undead Knowledge.

These are the most basic things, Gu Xi quickly understood some of the information.

I read through the contents of this book.

However, Gu Xi also noticed that his skin began to change while he was reading.

This was the effect of the magic books, so Gu Xi had to stand up and relax every thirty minutes of reading, and then sit down to read again after five or six minutes.

Otherwise, he would read the reader being swallowed by darkness, and in the end, he would never be able to return from the darkness.

These are lessons learned through blood and tears at the Minggu Bone Wind Academy.

Gu Xi had a classmate who was incredibly diligent and ambitious in his studies.

He hurriedly read the Book of the Dead for three days, hoping to boost his Undead Knowledge in one fell swoop.

One morning, Gu Xi and his classmates discovered that he had turned into a Zombie holding a book of the dead, and would just keep flipping through the book in his hands.

That student is still locked next to the big tree below the teaching building.

Gu Xi didn't want to end up like that, so even though he knew time was tight, he didn't intend to read frantically.

Every now and then, he would get up and relax, and sometimes he would even go out of his room to wander around other rooms.
