Yet William misunderstood the real intentions of the headmaster.
"Come, I have a business to discuss with you," out of the blue the headmaster said these words before turning to the rest, "everyone else leave now. This matter is closed."
Although Guo and his gang of traitors didn't like such an ending, they had no other choice but to leave. William watched them walk away while dragging their legs and lowering their heads. No matter what, this clash ended up with his victory.
"Send for my son to come," just as William and the two girls followed the headmaster back to his throne, he ordered one of the servants. "Tell me, do you know what toxin this was?"
As the headmaster asked, William didn't hide his knowledge about it. "I have learnt little about toxins, and that one is a nasty toxin."
"Hmm…" the headmaster seemed to think about something, "I heard you have a mysterious master who excels in forging, but never knew she also is an expert in toxins."
William didn't feel weird for the headmaster to know about his little white lie. But if he had to cover up many of his brilliant actions, he was now more than happy to stick closer to such a lie.
"My master isn't just a forging master. She is a formidable spirit master who is experienced at many things," he said while adding more mystery to his master, adding more layers of protection for himself.
"That's great then," the headmaster sat on his throne while William sat on one of the smaller seats in the front. The two girls were acting respectful and silently stood just half a metre away from William.
"Do you know that my son died a few years ago?" The headmaster suddenly said something out of the blue that made William surprised. He looked at the old man with a questionable gaze while the headmaster bitterly smiled.
"I had one son, and he had one son and one daughter. The daughter is around your age, in the third year class right now. As for my grandson…" the face of the headmaster changed.
For a brief moment, William noticed a flash of sorrow and regret over the face of that old man. At this brief moment, it looked like the headmaster aged decades over his years, looked so old and quite miserable.
But that didn't last but for more than one second. The headmaster sucked a deep breath in, controlled his ragged emotions before his face returned to its normal.
"My grandson is like a son to me, after all my legacy and my family's legacy will be inherited by him," he said while his eyes returned to fall on William, "but as my son mysteriously died at such a young age, his son is also following in his footsteps. Fifteen years of age but he is still limited to class four in the academy."
"Isn't it considered good?" William knew that by the standards of this world, being fifteen years of age and becoming a fourth year student here wasn't that bad.
Yet if he compared this dude with his little sister, then he'd be doing a little worse than her.
"If I told you he had been stuck there for four years, what would you say?" the old man dejectedly said before adding, "our family is world famous for the rapid ascension of our spirit power. He can't stay there for all these years without a reason, and…"
The old man didn't say more, yet William could already read in between the lines and guess what the headmaster wanted to say.
"Did you suspect he got poisoned by the same toxin?" William asked, "or did you smell its awful arsenic scent before coming out from his body?"
The eyes of the old man shone. For a moment there, a merciless pressure exuded uncontrollably from him. William strengthened himself in response using his spirit power. Yet he failed to sustain the pressure.
He used his full spirit power, but it wasn't enough to face such a mighty and berserk aura of a formidable spirit master.
In the end, William had to stand up from his seat as he staggered a few steps behind. As for the two girls, they both screamed in fright, ending up falling to the ground in trembling bodies. As for William, he had his entire body drenched in sweat under the pressure he was facing.
Despite the immense pain he felt, he didn't shout or scream like the two girls. He simply gritted his teeth, and tried to resist and persist, not falling to the ground.
"If I found out that my son and his son were poisoned with that nasty toxin… The ones responsible for this…" the old man said the moment his aura went out of control, in an icy cold tone.
Then in the next second, he recalled his aura and spirit power back, stopping the pressure William and the two girls suffered from.
"Sorry about that," the headmaster said in an honest and apologetic tone, "I only need to ask a favour from you. Can you check him out for me? He is now my sole heir, the one who is supposed to inherit my place in the next few years."
Despite William not liking the unjust treatment this old man was treating his two grandson and granddaughter with, he didn't refuse to help the headmaster.
"I'll see what I can do," William didn't promise him much. After all, he got lucky to see the toxin in its preliminary inactive form. If that toxin went into one of the girls' bodies back then, he would stand powerless and couldn't do much.
Getting exposed to this toxin would only leave a weakening effect on any spirit master. But if he got repeatedly poisoned, then the situation would greatly differ.
If the spirit master got poisoned for a long time, it would affect his spirit power growth, stagnating him at his current level of strength.
