Master and Tang San were even more shocked. The support ability of Nine-Hearted Begonia was already terrifying, so how terrifying would Nine Spirits Black Begonia be?
Master knew about the nature of mutated martial souls; they either weaken or strengthen. But there is a ninety percent chance of weakening, similar to how offspring of close relatives may be dull-witted, though there is a tiny chance they could become exceptionally wise.
Like his own martial soul, which is a malignant mutation, unable to break through level thirty for life.
Master said, "Since your martial soul is a mutation for the better, you will surely possess unimaginable support abilities in the future. But are you really not a twin martial soul?"
Ye Yu smiled wryly, "No, or perhaps not at the moment."
Master frowned, "That's odd. Based on my theory, you are more likely than Xiao San to be a twin martial soul, but you're not."
Master hadn't expected to make a mistake, he had miscalculated.
Master inquired, "Xiao Yu, do you feel that your future soul techniques will just be healing?"
Nine-Hearted Begonia has only one skill, healing, but since it is a mutation into Nine Spirits Black Begonia, perhaps it is different. Master hoped in his heart that Ye Yu's Nine Spirits Black Begonia would have more support than just healing.
Ye Yu said, "Though I'm not sure, I feel there's not only healing, because I can sense Nine Spirits Black Begonia has not only gentleness but also strength."
Upon hearing this, Master thought that there should be more than one skill. If it can possess power, defense, etc., then it would be formidable. Combined with Ye Yu's terrifying constitution, even though a support soul master, might not be easily handled by war soul masters.
Support soul masters are inherently weak and need others' protection. Master felt that a combat support soul master would be born in the future.
Ye Yu looked at Tang San, though he knew Tang San was a twin martial soul, he still had to act surprised.
"Xiao San, are you a twin martial soul?"
Master felt awkward at once, he originally thought they both knew, but obviously, Ye Yu didn't know Tang San was a twin martial soul.
If he had known earlier, he would have talked to them separately.
Master apologized, "Xiao San, sorry, I thought you knew each other."
Tang San said, "Yes, I'm a twin martial soul, but Xiao Yu didn't know. Master, you don't need to feel sorry, Xiao Yu is my good friend, it's okay for him to know."
Ye Yu nodded, assuring, "Yes, I won't tell anyone."
Master nodded, no longer feeling conflicted inside.
Tang San was curious, "Master, how did you know I was a twin martial soul?"
Though Master's prediction about Ye Yu was wrong, perhaps Ye Yu was an exception, Master must have his own theoretical reasons.
Master explained, "I once investigated six hundred and forty-seven people with martial souls as Blue Silver Grass, only sixteen possessed soul power, and none exceeded level one, but you had innate full soul power. According to one of the core competencies of martial soul theory, soul power is directly proportional to martial soul quality. High soul power implies a strong martial soul, yet your martial soul is Blue Silver Grass, indicating you surely have another martial soul, and it must be very powerful, corresponding with innate full soul power."
Master was confident inside, his inference was undoubtedly correct, Tang San's martial soul must be famous, something he was aware of.
Tang San nodded, "I see."
Meanwhile, he felt admiration, indeed Master had unique qualities.
"Master, I wish to be your student," Tang San sincerely said.
Ye Yu naturally also wished to, under Master's guidance, he would greatly benefit. Although Master's strength was not formidable, in certain aspects, he was 'invincible'. Being taught by Master was advantageous.
Master was very pleased, "Good, from now on, you may call me teacher."
Master's gaze again fell on Ye Yu, still puzzled why there was no second martial soul.
Had he not witnessed Ye Yu's terrifying power before, he would have thought he was wrong, considering Ye Yu's martial soul a wasted martial soul. Now it seemed, the mutated Nine Spirits Black Begonia, matched perfectly with innate full soul power. However, why was his constitution so strong? This surely wasn't because of Nine Spirits Black Begonia, support martial souls cannot alter one's constitution.
"It appears there's much more knowledge I need to dive into," Master felt he needed to understand more.
Master looked at Tang San, asked, "Xiao San, can you release your other martial soul for a look? If you mind, don't need to release it."
"I don't mind, I'll release it now."
Although his father said not to show his second martial soul casually, Xiao Yu was his friend, Master was his teacher, akin to a 'father', after all, once someone is a teacher, for life they're like a father.
Tang San had no reservations, raised his left hand and opened it, azure light bloomed, a small hammer emerged.
Seeing this hammer, Master's eyes revealed shock. Knowing Xiao San's second martial soul was extraordinary, but hadn't expected it to be…
"Since Xiao San's surname is Tang… I should've guessed."
Master suppressed the excitement within, "Alright, put it away. Remember, don't casually use your second martial soul in the future, and don't add soul rings to it."
Master's statement made Tang San more curious.
"My father also told me the same, Master, why is this?"
Master was equally curious, "Xiao San, what does your father do?"
"My father is a blacksmith."
Upon hearing this, Master was surprised. He naturally understood, it wasn't just as simple as being a blacksmith.
"Seems Xiao San doesn't know his father's true identity, then now's not the time to tell him detailed reasons."
Master said, "It isn't time to tell you yet, just know that my and your father's request is for your own good."
Tang San nodded, asking no more.
Master said, "Alright, I'll take you to register. Tomorrow's the opening ceremony, then classes officially start the day after. After the ceremony ends tomorrow, I'll take you to find a suitable soul ring. Tonight, I'll start thinking about what kind of soul ring suits you best."
Tang San felt a bit excited inside, he'd soon be able to obtain a soul ring, perhaps the Profound Celestial Skill would also break through as he stepped into being a soul master.
Master earnestly said, "Although I'm there to help, absorbing soul rings depends on you. If it's a soul ring of ten or several decades, absorbing it is fine, but I demand the optimal soul ring configuration. The first soul ring must reach a hundred years."
Tang San nodded, "Yes, I also think so, the first soul ring should not be less than a hundred years."
Master continued, "The first soul ring should best be three hundred years, with my strength, it can be resolved, absorbing won't be too impossible."
After Master finished, he prepared to take Ye Yu and Tang San to register, but at this moment, Ye Yu uttered something that directly stunned Master.
"Teacher, can you kill a thousand-year soul beast?"
