The dragon roared causing the entire area to vibrate. Just from that alone I could tell how strong it was.

The litch called it ancient dragon.

That would mean that before it died, it lived at most 1000 to 2000 years. As with all creatures on this world, the longer they live, the stronger they become.

I could even tell that Skyrith was holding back on me yesterday. I was only acting tough.

My goal was wiping out the undead army.

My hair turned partially white as my senses heightened. I gathered spirits inside my right arm and underwent 《Partial Spirit Manifestation》.

The world underwent a change as everything seemed to lose colour.

The approaching dragon also stopped moving entirely.

“What should I call this?”

I contemplated on my new move which was obtained from ancient spirit magic. The great thing was that I could use light magic to strengthen this technique.

“Kek.”

I then chuckled and made a blade shape with my hand. A golden light spread through my finger and formed a giant golden blade.

“With the love of the spirits!” I lifted my arm into the air with a chuuni pose and both my feet spread apart, “The light shall vanquish evil and bring relief to the good! Bring upon this mortal the power to rid impurities from the mortal realm!”

The light ripped through space as it grew in size. A giant sword manifested which released a tremendous amount of energy.

“With the destruction of light, comes the power to crush my opposition!!”

I remembered something I heard in my dream and in fiction back in my old world. It’s a sword spoke about in many legend on earth. Many of the Isekai MC’s are able to use the sword’s power once they become cheat swordsmen.

“Become my light and cut the darkness! [Spirit Excalibur]!”

My icy cold voice resonated throughout a world with no sound. Even the golden sword had no sound.

I swung down my arm and along with that the manifested giant blade called 《Spirit Excalibur》 followed.

WOOOOOOING—!

Only two seconds had passed in the real world.

Crack—!

The sky broke apart like glass and then–

Boom—!

Boom—!

The dragon was sliced in half along with a majority of the undead army. A humongous tear was in the ground they stood on.

A large arc of light was left behind since time was still catching up to the light sword I conjured with spirits.

I think I destroyed about 40 percent of his army along with the undead dragon.

“Huh?”

The world returned back to normal after space broke apart my technique.

The litch looked around with an open jaw. He didn’t have a face so I couldn’t tell his expression very well.

Is it surprise? Or perhaps fear?

No, it was neither…

“Ku… Kukukuku.”

I stood there with a confused expression when I saw the undead laugh.

“Kukuku. I do not know what skill you just used but…” His mana skyrocketed for some reason, “OUR BATTLE SHALL BE LEGENDARY!!! Come! Shadow monsters!!”

Shadows rose from his feet and formed strange shapes of monsters. There were even some that looked like humans.

“Attack!!”

Multiple magic circles formed around him again.

‘Shit, another multi-caster mage.’

I gained distance from the shadows that ran towards me.

“Come forth, Undine!!”

A wall of water appeared out of nowhere; revealing a mature woman with blue skin and transparent hair.

“Yes, Master!!”

Undine summoned multiple water serpents that took down several shadow monsters.

“Summon Spirit Beast-[Hydra]!!”

Undine made a summoning magic circle which was as big as 20m.

WHOOOOSH—!

Smoke spread out from the circle and revealed a giant shadow.

ROOOOAR

A monster possessing multiple heads called a hydra. They are cousins of the World Serpent which is classified as one of the strongest monsters in this world.

‘Whoa, I didn’t know you’d be this strong…’

“It is because we are in the rich environment of the elves! I feel invincible!”

Oh, right. She could read my mind.

Undine seemed terribly excited to fight alongside me. It has been a few months since we last saw each other, after all. I was worried whether we lost contact with each other.

Her serpents and hydra fought against the monsters of the undead king.

I then saw a small red flickering spirit flying in the air.

‘Huh?’

It stood out amongst the blue and white spirits floating around.

I tried absorbing it into my body.

—!

When I did, I saw a completely different sight from before. Along with the light and water spirits, even fire spirits roamed around me and tried synching their energies with mine.

–King?

–Burn them all! Die! Die!

–Ash! Burn them down! Suffer in the flames of Hell!

They were spouting some really crazy lines unlike the playful water spirits. If I were to compare the two; the water spirits were the disciplined students while the red spirits were the delinquents.

I felt a powerful gaze amongst the fire spirits.

A red giant of a man with a burning beard crossed his arms. He grunted when he saw me. I thought I was hallucinating.

“Master!” I then heard Undine calling out to me, “Ifrit has agreed to give you authority over fire!”

I shivered.

The monarch of the most destructive element really wanted to synchronize with me.

I then heard his voice.

–I shall burn their very souls to ashes, my lord. Please allow me to materialize in your world. You shall not regret having my flames by your side.

‘Undead are weak against fire, right? Maybe it could work...’

Maybe it was only possible for me to see Ifrit because we were right below the World Tree.

A powerful heat spread through the surroundings.

A bright light then landed in the middle of the undead king and us.

–YOUR ANGUISH SHALL BECOME THE FUEL OF MY ELEMENT, YOU SPAWN OF FORBIDDEN MAGIC!

A muscular man with red burning skin and flaming hair appeared.

“Onwards, Ifrit!!”

–Yes, my lord! [Dragon’s Breath]!”

His chest swelled up as he inhaled.

BOOM—!

A powerful force of energy came out of his mouth and headed for the litch. The surroundings was bathed in the powerful surge of flames.

“Two spirit monarchs!? What the hell are you!? You can use human magic and elven magic!?”

His surprised voice reached me within all the chaos.

He casted a giant barrier that seemed to be strong enough to block Ifrit’s attack. But that was useless.

Probably knowing that undead was weak against fire, he used [Flight] to fly into the sky. A few hundred more of his skeletons were burned to ashes.

‘Damn. He’s overpowered.’

I had never seen such destruction. I was positive that I wouldn’t be able to cause that same amount of destruction if I casted that spell. It’s pretty amazing that he copied a dragon’s technique. There was this legend that fire spirits were the ones who taught dragons how to use dragon’s breath. It sounded stupid but after comparing Ifrit’s breath with the Edna’s, I started to believe that legend.

Then again, the consumption was a lot. I felt my spirit core being drained by half from that single attack that wiped 20% more of the undead army. My core is used as a fuel tank for them to cast their magic.

Since it was a contract, it was my responsibility to gather all the spirits inside my body so they could fight for me. The downside of that was that I couldn’t use arcane magic. I might break my concentration of gathering spirits. I had to switch between the two.

“Magnificent, human. You truly exceeded my expectations. Here I thought I didn’t have to use my strongest spells.”

“Huh?”

A giant cluster of energy appeared behind him. The dense sphere was black and releasing a force similar to spatial magic.

I tilted my head and lifted my arm.

“Now taste a spell similar to a black hole–“

Whoosh—!

The spell vanished into nothing but mana.

“…Huh?”

The mana gathered around my white spirit arm and was absorbed. I felt the mana enter my body and made it my own.

“…What just happened…”

The undead litch was staring at me with a fiery gaze.

My two spirits were still fighting his summoned monsters.

I also flew into the air using [Flight].

“You are quite the troublesome fellow. Your technique that allows you break apart magic is outstanding but...” Dark mana circulated into a magic circle, “Why have you not used it against my undead yet?”

Shit. He noticed that I couldn’t dispel his undead army. Since the undead army was summoned with black magic, I couldn’t break it apart. My Mana Bending didn’t work for black mana.

“Fuck...”

I chanted my next spell in my head.

High rank magic–[Element Vortex]

I could combine all three nature elements; which is water, fire and wind in a single spell. Earth magic is excluded since it’s a physical manipulation of an element. Throwing some rocks wasn’t impressive. And even if I wanted to then I could just use [Telekinesis]. Sure, water was the same but the difference was that water could be combined with other sub elements. Take space for example. Using my control over space, I could amplify its power. I could perhaps alter the spell to be similar in power to underwater pressure of 10000m. That depth could literally crush human bones.

With fire, the hotter the fire, the more destructive the power.

“[Abyss].”

“[Elemental Vortex]!”

Both of us threw our spells at each other.

BOOM—!

Rumble—!

The air itself became several times heavier when our spell collided.
