One, two, three times...

Over and over again, Andre ran between the cemetery and the stone house, feeding the balls of skeleton soul fire to the dark knight, Darkening.

Facing Andre , whose cranium flickered with soul fire, the once defiant Dark Knight lost all courage to say anything more. He obediently devoured the soul fire and, after a brief digestion, immediately converted it into dark power to release the Dark Impact.

However, failure after failure was still inevitable, which slowly bred a violent mood in the heart of Dark Knight Darkening.

Why?

Why, after each time he input metal power into the inserted bone tube, could he not succeed?!

Feeling that his mental strength was only enough for one more use, Dark Knight Darkening first sent a consciousness to Andre that he needed to replenish with skeleton soul fire. Then, without conscious control, he simply wanted to release the last Dark Impact at will.

Crackle crackle—

...

The skeleton mage that Andre had ordered not to move suddenly took three stumbling steps back, hit the wall of the stone house, and finally sat down on the ground!

“...Quickly tell me, how did you do it just now?!”

After being stunned for a second or two, Andre , who was about to leave the stone house, turned around and pounced like a hungry tiger, grabbing the Dark Knight Darkening's head knot and shaking it desperately.

"Ugh—"

The Dark Knight, whose soul fire energy was weakening, simply vomited, spat out a thin wisp of energy, and then his two blood-red eyes hidden under the iron armor started to spin circles...

"Oh, I'm sorry! I didn't know you would get dizzy when shaken, I'm sorry, I'm sorry."

In high spirits, Andre looked much more favorably upon the Dark Knight Darkening. Upon realizing that the Dark Knight was dizzy, Andre muttered to himself, "This horse-riding guy, he actually gets dizzy from a couple of shakes?

Although he thought so, he still calmly placed the Dark Knight's head back on the stone table.

"Ugh—, I just wanted to release the last Dark Impact, and I didn't think about anything else. I don't know why the release was successful."

The dazed Dark Knight took a long break before barely regaining his strength, and then replied to Andre 's question with a dizziness.

Succeeded without thinking about anything?

Now it was Andre 's turn to be dizzy. What was going on? Andre felt it was necessary to recall and review the entire process—

This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.

Hmm...

At first, he used the skeleton mage as an experiment, carving lines on them, trying to use the lines to induce and accelerate the casting time of the spell.

The final result was failure.

Then he used metal bones condensed into tubes, and in a hurry, he directly inserted them into the Dark Knight's head, commanding the Dark Knight Darkening to release the dark power from the metal bones, and also demanded that he report whether the spell was accelerated after success.

"The speed of the Dark Impact, about... well, it's a lot faster."

Finally getting rid of the dizziness, the Dark Knight Darkening spat out the last bubble of energy and hurriedly continued to report to Andre . If he didn't report, it would be a violation of the master-servant contract, and his soul fire would be cursed by the God of Death. which is not fun at all...

However, the Dark Knight Darkening had not studied mathematics, and he could not clearly express to Andre how much faster the spell was, and could only vaguely use metaphors.

Andre glared at Darkening—how much faster is a lot? Isn't that just nonsense? It seems that he still needs to continue testing with the skeleton mage.

But through what the Dark Knight Darkening said, Andre could be sure of one thing—there was no problem with all the guesses he made before, not to mention breaking the laws of the undead, at least he, Andre , could summarize some favorable ones for himself, and ultimately arm his own gang!

This is as good as buying a lottery ticket and accidentally winning five million!

After suppressing his emotions, Andre nodded at the Dark Knight and rushed out of the stone house with his shoulder blades, and soon came back with a pinch of skeleton soul fire.

"Devour it, and then continue to release the Dark Impact."

Upon hearing Andre 's words, the Dark Knight Darkening almost fainted again. Such an unpalatable skeleton soul fire... he has eaten almost ten today! But Darkening could not disobey Andre 's command now, and could only swallow and absorb the skeleton soul fire.

With the first success, this time the Dark Knight Darkening succeeded again after failing three times, just like the first success, without thinking about anything, just subconsciously injecting the converted dark power into the metal bone, and he could succeed.

After Darkening succeeded several times in a row, Andre casually dragged a modified skeleton mage over and asked the skeleton mage, who had recovered a lot of mental strength, to release the White Bone Binding again.

Strangely, although the skeleton mage's White Bone Binding could always succeed, the speed was still at least three seconds.

Why is it strange? Why was the Dark Knight Darkening accelerated, but the skeleton mage's incident speed remained unchanged? They were both upgraded and modified by themselves, with rich metal bone lines added, but why is the difference so big?!

Andre paced back and forth in the dimly lit stone house, and several skeleton mage servants stood in place without receiving his command, turning their bone heads back and forth as Andre walked around...

They were all attached with metal bones, but where is the difference?

Andre couldn't help but reach out and scratch his head. He used a little more force and actually made the skull head creak and creak.

Eh... when did the crack on the back of the head appear, if the gap is wider, even the finger bone can be inserted... insert?!

Right! Insert it!

A flash of insight struck Andre 's mind, and he suddenly figured out the crux of the whole problem—

When modifying the skeleton mage, the metal bone stopped outside the skull, but when experimenting with the Dark Knight, the metal bone was directly inserted into his head!

"Darkening, did the metal bone inserted into your brain contact your soul fire?"

Andre figured out the key issue and naturally went to ask for confirmation immediately.

"That bone penetrated through my soul fire."

The Dark Knight Darkening answered honestly. In fact, he really wanted Andre to help him pull out the uncomfortable metal bone, but he was afraid of Andre 's tyranny from the beginning and didn't dare to say more.

"Hahaha - I guessed it right! My approach is not wrong, the law of the undead can indeed be changed and utilized!!"

Andre slapped his head and crossed his arms over his waist, laughing at the sky.

It's over!

The Dark Knight Darkening's soul fire trembled—

His owner is crazy...
