The next day...

Inside the training room, Jeremy was currently practicing his null elemental spells.

For many eras, Jeremy had been finding the truth of the planet Earth's whereabouts.

Where was Earth exactly situated?

Was it situated from the same universe as Ortus or not?

Still...

He couldn't find the actual answer to that question at all, as he didn't even know where Earth was anymore after being teleported into Ortus.

Fortunately, Earth still existed in this timeline...

So, Jeremy decided to do experiments to find out the answer to his long-lived curiosity. Firstly, he started casting some simple spells that the Ancient Mages used until the slightly more complex spells of the Modernistic Mages.

Right after that, he tested many other things such as Spell Formulas, incantations of various Runes including Runes Spells, some of the very simple revised arrays, Rune Enchantment on the wooden dummies, and lastly, the loathed ritual of most mages.

Of course, he did the ritual and prayed to himself. In the first place, Jeremy didn't dare pray for any forbidden existence.

After all of the experiments were finished. Jeremy finally came to the conclusion that Earth was in the same universe as Ortus.

What did that mean then?

It meant that the rules and laws of everything that he got used to on Ortus could also be applied here on Earth.

This was one of the questions that he really wanted to know in his previous life.

And now, he finally knew the answer...

Just like that, Jeremy had been practicing for quite some time already. Right now, he felt that his mana pools inside his dantians were almost running dry.

After all, he was still only an Apprentice Mage. His mana amount was quite limited by the size of his mana whirlpools, and his class rank was still low, of which he was not even a class 1 True Mage as of yet.

At the moment, it was already a miracle that he could still practice magic for a bit more before he became utterly exhausted.

It was all thanks to the pure mana particles he had been using to practice for a while now.

It was a miracle already that this planet had mana particles. Furthermore, it was even the purest of the purest mana at that.

Because of the pureness of those mana energy particles, he now could cast a spell with higher effectiveness and higher efficiency with less amount of mana used.

Right now, there was an almost transparent ball shaded with light blue color floating above Jeremy's hand. Then it started to move and rotate rapidly around his body.

Its shape was continuously being changed according to Jeremy's commands.

Then when it flew out to around 2 meters from Jeremy's body. It started to shake a little until after it reached 3 meters away from his body, its structures began to change from a ball into a seemingly unstable water balloon.

And when it had reached 5 meters away from his body, the mana ball finally dropped to the ground and dissipated into thin air.

That signified that the radius of his mana control was about 5 meters. That meant the farthest mana barrier he could create was also around 5 meters.

However, the barrier structures, mana cost-effectiveness, mana cost-efficiency, and its potency wouldn't be satisfying in the least.

If he wanted to create a mana barrier at the 5 meters range away from his body, it would cost him his own leg at the very least.

In contrast, if he created a mana barrier at around 2 meters around his body, it could still be as stable as when it was generated around his body directly.

Well, anyone might be confused that he already had a mana field at around 10 centimeters outside his body at all times; why did he still need a manual mana barrier to protect himself?

It was simple...

That was because a mage was a powerful yet fragile existence at the same time.

They were at their strongest in long-range and when they were prepared enough, but they were very frail and feeble at close range and when they were ambushed abruptly without any preparation.

That's why every mage needed to have hidden cards and hidden measures as many as possible.

And this mana barrier was the second protective measure of most mages to protect them from external threats.

Next, he tried to throw a mana ball the size of a tennis ball at a dummy at around 20 meters in front of him.

First of all, he created a mana ball on his right palm at a breakneck pace. The process and time used to create a mana ball could also signify one's talent in magic, precisely a talent in combat magic.

The faster they could create a spell, the higher their chance to win the fight.

After that, while the ball was gaining a circular shape, Jeremy started to chant some unknown language and use his left-hand index finger to write runes near the mana ball.

When Jeremy finished chanting, the runes that he had written on the vicinity of the ball-shaped mana suddenly permeated into the ball until they disappeared wholly inside.

Subsequently, Jeremy postured his body like a baseball pitcher who was going to throw a ball.

Then...

'[Mana Bolt]' Jeremy thought lightly in his mind.

*Whoosh*

The mana bolt that was accelerated by Jeremy's throwing force, including his mental force coming from the precise control of his own mind power, generating a very fast speed mana bolt that was almost untraceable by the naked eyes.

Well, even with this high speed of travel, the mana bolt still remained its shape as a spherical shape.

And it was currently going in a straight line to the target?

No...

It was actually curving to left then right along the way. Sometimes, it was even going up and down, producing a very unpredictable trajectory if anyone was able to see it in the first place.

Because it was just too fast...

Then...

*Booomm!!*

The sounds akin to a dynamite explosion occurred within the close-shut garage generating chaotic and turbulent air within.

The dust and unknown powder were blown away in every direction. historical

*Cough* *Cough*

"D*mn... *Cough*... *Cough*... it." Said Jeremy while coughing nonstop.

Jeremy then hurriedly ran outside of the garage, waiting for the dust to settle down.

After a few minutes, he walked back inside to inspect the result of his deeds.

What was waiting for him was an astonishing sight of the heavy wooden dummy that was almost indestructible by ordinary people's force...

It was now missing its head and some parts of its upper torso...

Jeremy's face twitched a bit from the sight in front of him because even from when he was a former sage, he couldn't produce the same result while using the same amount of mana as a moment ago.

'I'm truly surprised by the result. This was good, really good. Suddenly, I feel like my future is so bright ahead.' Jeremy thought satisfactorily after seeing that he had half destroyed the dummy.

Even with this much astonishing result, Jeremy didn't show body signs or express anything outwardly.

After all, he was the one who had experienced heaven and hell first hand.

He had even undergone something much more astonishing than these things, like when his impenetrable and indestructible mana barrier and mana field were being forced through quickly like butter by the enemy assassins. Or when he went back in time with a 9th circle spell that shouldn't be possible to use when he was only a sage.

In the past, he even fought with dragons and demigods.

He wouldn't let something like this cause him to get ahead of himself.

He was a man of culture, after all.
