Another three days passed in a flash. The students of Tianwei Academy were mostly busy preparing for the upcoming promotion assessments.
The so-called promotion assessments naturally included both cultural theory courses and evaluations of their cultivation realms.
To advance from yellow-tier students to mystical-tier students, they must have opened at least ten meridian gates. Otherwise, they would remain yellow-tier students. If they failed to advance after a second assessment, they would be ruthlessly expelled from Tianwei Academy.
As for the cultural theory courses, they accounted for twenty percent of the overall assessment. Although not too important, poor performance in these courses would still affect their promotion.
During this time period, both martial arts instructors and theory course mentors were undoubtedly the busiest.
On this day, Su Qingxuan finished her class as usual and returned to her residence, only to find a guest in her courtyard.
Seeing the middle-aged man tending to the weeds in the medicinal herb field, Su Qingxuan was momentarily stunned.
"Yes," Su Dongling nodded slightly, turned to look at Su Qingxuan, and smiled. "Not bad, your cultivation has improved quite a bit over the past six months."
Su Qingxuan squinted her eyes and smiled, quickly walking over to Su Dongling and hugging his arm. "Of course!"
Su Dongling looked at his daughter dotingly. Over the years, as he traveled far and wide, his only concern was this precious daughter.
The father and daughter entered the loft. Su Qingxuan hurriedly poured tea for her father and asked, "Daddy, when did you come back?"
"A few days ago," Su Dongling replied with a faint smile. "I first went to the Alchemist Guild."
"Hmph, so in daddy's heart, alchemy is more important than your daughter!" Su Qingxuan pouted, feeling a bit jealous.
"Silly girl," Su Dongling shook his head with a smile. "By the way, did you complete the pill formula I left with you?"
"Of course!" Su Qingxuan chuckled. "I completed it just recently."
"Oh? That means your alchemy skills have improved rapidly."
Su Dongling nodded before saying, "Let me see the pill formula. And since you completed it, do you have a sample of the Purple Light Dust Pill?"
"Here you go." Su Qingxuan made a hand gesture and took out a slightly yellowed scroll and a jade box from her storage spirit ring. "I knew you would want to test the pill."
"You little trickster!"
Su Dongling unrolled the scroll and found the additional medicinal ingredients, proportions, and ages before silently nodding in approval. He was even more surprised by the fire control techniques described at the end.
"Uh... Did you really complete this?"
Su Dongling looked at his daughter in disbelief. This wasn't just completing a pill formula; it was perfecting one.
If Su Qingxuan had truly done this, then her alchemy skills might be on par with a sixth-grade advanced alchemist, not much lower than his own.
"What is it?" Su Qingxuan pouted, feeling a bit guilty.
"You little girl." Su Dongling took a deep breath, opened the jade box, and swallowed the pill inside.
After a moment, he slowly said, "Three times the efficacy of a normal Purple Light Dust Pill. Girl, who helped you with this? Tell me the truth."
Su Qingxuan blushed and bit her lip, "Why couldn't it be me who completed it by myself?"
"You little girl, if you could perfect the Purple Light Dust Pill formula to this level, what need would there be for me to teach you anything? Your alchemy skills wouldn't be much different from mine."
Su Qingxuan's eyes widened in surprise. "I didn't know he was that skilled!"
"Hehe!" Su Dongling lightly tapped Su Qingxuan's forehead with a faint smile. "Did you ask your Uncle Hong for help?"
"No." Su Qingxuan bit her lip, looking a bit embarrassed. "Actually, I sought help from one of my students."
"A student?" A figure flashed in Su Dongling's mind, and he quickly asked, "What's his name?"
"Ling Feng!" A gleam flashed in Su Dongling's eyes. "So it's him?"
"Daddy, you've met Ling Feng already?" Su Qingxuan asked in surprise.
"Yes, if it's that boy, then it's not surprising. His alchemy skills are truly rare," Su Dongling laughed heartily. "I knew it! His method of refining medicinal liquids bears some resemblance to the technique I created. It turns out that you taught him."
"Taught?" Su Qingxuan shook her head repeatedly. "Daddy, I didn't teach him anything. He just watched me refine a pill once."
"What!?" Su Dongling almost jumped out of his seat. "You mean he grasped a part of my Nine Spirits Refining Method just by watching once? Incredible, truly incredible!"
Su Dongling couldn't help but rub his hands together in excitement. This boy is the perfect successor for my poison master skills!
Even Su Qingxuan, due to her limited talent, might not become a truly top-tier poison master.
"Daddy, I promised him that after you taught me the Nine Refinements of Mystic Fire, I would pass it on to him." Su Qingxuan bit her lip, looking pitiful. "Now that you know I didn't complete the pill formula, will you still teach me the Nine Refinements of Mystic Fire?"
"You little rascal, stop acting pitiful." Su Dongling rolled his eyes. "All my skills will eventually be passed on to you anyway. I'll teach you. With your current level in alchemy, it's time you learned the Nine Refinements of Mystic Fire."
"Haha, thank you, Daddy! You're the best!"
Su Qingxuan cheered, acting like a lively little girl in front of her father, which was a stark contrast to her cold demeanor as Mentor Su in the classroom.
"But, there's one more thing I need to tell you," Su Dongling said seriously, looking at his daughter.
"What is it?" Su Qingxuan blinked her bright eyes in confusion.
"You can teach Ling Feng the Nine Refinements of Mystic Fire, I have no objections. But you also need to give him something else."
"The essence of my years of experience and the knowledge from past masters... The Classic Formula of Ten-thousand Poisons I personally compiled."
"What...? Daddy, isn't that your life's work? Why don't you give it to him yourself?"
"That boy is already Yan Cangtian's disciple. I wouldn't stoop to snatching Elder Yan's student. But since he has the potential to become a poison master, there's no harm in nurturing him."
Finding a good candidate to become a poison master was extremely difficult. Despite traveling far and wide for many years, Su Dongling hadn't found a suitable successor until now with Ling Feng. Even though they were not destined to be master and disciple, to ensure his teachings didn't die out, he decided to give the Classic Formula of Ten-thousand Poisons to Ling Feng.
Of course, Su Dongling also had some personal motives. Although Ling Feng couldn't be his disciple, his daughter seemed to have a favorable impression of the boy.
If not a disciple, having him as a son-in-law wouldn't be a bad outcome either!
