After telling the headmaster about what he felt, the two stood around the hole and felt how simple and yet tricky it was to bypass that array.
The two discovered that the hole wasn't covered with the array energy, not sealing anything at all from them.
When they sent their senses through that hole, they managed to cross the insurmountable edge of the array and see what was inside.
Starting from there, the two started to try out different ways until they finally managed to totally bypass the array without the need of any holes or gaps in the ground.
Even with such devastation around, William's array covered everything up. So, outside the array, things looked quite normal.
Besides, they wanted to find a reliable method they could use in different situations to eavesdrop over the meetings and bases of the dark spirit masters without alerting them.
"Let's see what that little devil is doing inside my place," once the two finally learnt the right way to break the array, the way that even William didn't know about, the headmaster was more eager to try it out.
It happened just at the moment when William was trying his combined technique out. And they saw what he was doing crystal clear this time.
William wanted to find a way to better control his stacked-up arcs of lightning over his sword.
He couldn't lower the number of these arcs below five, and so he wanted to see if he could find another way to handle such an issue.
"This…" However, the moment he finished executing his technique, he stood in the middle of the new crater he created with his sword, feeling a little puzzled and quite shocked.
He did exactly the same as he did last night, merged the two elements together. Five lighting arcs accumulated around the edge of his sword, yet when he released the attack, something new happened.
"What's going on?!" he stood motionless while looking at his sword. Last night he tried the technique and only managed to release one arc out of five.
Yet this time he released the five and his spirit power still had close to thirty percent of its total capacity.
This was something he never expected. And he didn't feel something happening to his technique or did anything different at all.
"I have to try it out again…" such a result came as a pure shock to him, one he never expected to happen without doing anything.
As he couldn't tell what caused such a change, he decided to retry it again. But first he sat on the ground and started to replenish his lost spirit power.
"What is this kid doing?" from far, the headmaster stood by the side of Kong as the two watched what William just did.
In their eyes, William moved quite fast for a spirit master in his rank. And the move he executed next was quite novel in the eyes of the headmaster.
"I… Never saw such a technique before…" Kong's eyes kept shimmering in mysterious light, "but no matter what he did, he isn't quite satisfied with it."
"I also felt so… And it's quite weird…" the headmaster paused before seriously adding, "such a move is enough to cross ranks and threaten stronger spirit masters. How come he isn't satisfied with it?"
"I don't know what's going on inside the head of that little devil anymore," Kong felt the same helplessness as his friend about William's technique.
In his eyes, he felt this technique was on the same level of his clan's formidable techniques. However, William seemed quite unsettled and unsatisfied. And that made him wonder about the reasons William had for such a response.
If he was in William's stead, he'd be quite thrilled about doing something like that.
Least to their knowledge that William wasn't satisfied as they felt, he was just puzzled and confused.
He felt like his technique was now more perfect than ever to get used in any battle. But as he didn't know what happened to drive out such change, he wasn't celebrating such a result yet.
After replenishing his lost spirit power, he stood up and tried to execute his new technique. This time his attention was totally focused over any change that might have brought such desirable results.
"No way! This… This… How come…!!!"
And when he executed the technique for the fourth time, he finally managed to find out what caused such change.
To his surprise, what brought such change came from something he never imagined doing so, the darkness element inside his spirit!
After repeatedly stirring up the darkness element, the element got easily activated. And as the first step in activating this element relied on the fast movement, the same first move he'd take to activate his combined technique, then his darkness element got activated as well.
And as the stacking part of his light element was similar in concept to his darkness move, the darkness inside his body started to act.
However, this wasn't as simple as it might seem. To unravel the full truth about this, he started to repeatedly use the technique until the early hours of the next day.
"So… This is it…" William muttered aloud to himself, not realising that every single word he'd say was picked up by two hungry wolves watching him right now, "I didn't move the sword in the same way as the Silent Moon technique required. So even when the darkness got stirred up, it wasn't enough to fiercely clash and antagonise the other two elements…"
He paused there and started to think again about the things he discovered after all these attempts.
He felt it crystal clear by now, his darkness element got activated, but not to the degree to start impacting his entire technique in a negative way.
Just this level of activation brought up an effect he never imagined or knew it existed before, a control effect!
The combined version of the two elements had one sole side effect, it was too overbearing and explosive to get executed properly by his current level of spirit power.
