If it proved that trying to control the direction of each strike consumed more, then he'd try to lower the number of strikes he'd control. For example, if he executed ten strikes or more to stack together using the dark element, then he'd just control two of them to block the path over his enemy.
He wanted to use the entrapping method of the Burning Star technique. And that to make sure his enemy wouldn't have a chance to escape from his incoming attack and end up losing too much or die in the end.
Not to mention any foe entrapped in such an attack wouldn't have the ability to fight back.
But when he witnessed how truly scary the attack combining part of this technique was, he started to think less about the entrapment portion.
In his mind, another variation of his new technique began to take shape. He imagined if he was able to merge both stacking part of the dark technique with the combining part of the light technique, how devastating his final technique would be?
*Boom!*
This time the explosion that came out from using just five slashes wasn't fierce like the first attempt. It also didn't suck his spirit power dry.
"As I thought… The hard part lies in trying to control the direction of each slash…" he examined his spirit power and found out that he depleted almost twenty percent of it in doing so.
Follow on NovᴇlEnglish.nᴇt"If I used ten strikes then…" he replenished his spirit power for ten minutes before returning to test his theory again.
"It caused the same devastating damage as the first attempt… And it only consumed thirty percent of my spirit power…" he now realised that by only focusing over combining his slashes, the damage was brutal, and the spirit power consumption wasn't that bad.
"So… If I tried to merge the lightning and light techniques together…" he grew curious about such a possibility. After all, the two elements were compatible with each other.
The lightning part he learnt consumed ten percent of his spirit power. So he hypothesised that after using the two parts together, around half of his spirit power would get consumed at most.
But when he tried, he found himself in an unexpected situation.
*Boom!*
He flashed fast, moved his sword ten times before landing the strike over the ground. This time the explosion was so severe that he even felt the ground trembling faintly under the tip of his sword.
The explosion was fierce enough to cause a much deeper crater in the ground, almost reaching to twenty metres in depth. At the same time, the two elements combined together and that brought up changes he never expected.
First the lightning started to arc and dance around his sword. With each full swinging move of the sword, one arc was produced, and William felt how deadly the energy inside was.
But when he executed the strike, he was bewildered to see only one arc slip through his sword and touch the ground. "Such a deadly strike came only from one arc. And there are nine others?!" he muttered in disbelief while lying on the ground again.
He raised his sword in front of his face, while his spirit power got almost depleted again. He didn't get why this happened. By his calculations, it was supposed for the spirit power to only decrease by forty up to fifty percent.
And that was by hitting with all the might his technique had. But reality proved how naive he was thinking before.
"Spirit power isn't that predictable, just like the fighting techniques and special spirit elements… Tsk!" He recalled one of the phrases he once heard. He learnt about it at one of the many lectures his master once gave to him, and it was related to this part.
He almost forgot such words as he never had any of these elements in his previous life. But as he was now seeing how things turned out, these words resurfaced again, solving this puzzlement out for him.
It wasn't like one plus one equalled two. In this case, trying to merge the two special elements together yielded much different result than the one he thought before.
And that made him wonder what it would be like when merging the three elements together.
"At least I had a technique that can hit many opponents at the same time…"
*Rumble!* *Rumble!* *Rumble!*
Follow on Novᴇl-Onlinᴇ.cᴏmHe sat down and prepared to replenish his lost spirit power, muttering to himself such a good point about his attempt while throwing the sword away.
And when the sword touched the ground, it uncontrollably released the stacked nine attacks in succession.
The ground shook like it was the end of the world. And gradually William felt the ground he sat on caved in slightly with each explosive rumble.
When the dust settled, William could see a hole that extended for almost fifty metres at its centre. The edges looked like a slope of a mountain, and this hole encompassed most of the garden here.
He found himself sitting on that sloppy part.
"I can't imagine the look on that headmaster's face when he sees this…" When William saw such irreparable devastation, he could only inwardly sigh and accept such a result.
He shifted his attention from worrying about what possibly could happen to him thanks to his actions here from the headmaster and focused on how to solve this big problem he had.
When he unleashed that arc from before, he could feel his spirit power getting sucked dry by this attack. "I can't show the full power of such an attack before getting to silver… Even to gold grade at least…" he pondered about this and felt more helpless.
All the answers he found required him to get stronger. He wanted a solution for his current problem, not something for tomorrow.
"This attack… It better suits thrown out objects…" as he thought about it for much longer, he recalled the great damage the nine arcs combined did.
