Han Feng followed Su Qian to the outskirts of the Inner Academy.
After opening the space gate, the two flew towards the Outer Academy.
The location of the Library Pavilion was not in the Inner Academy, so they had to make a long trip.
Fortunately, the two were not slow. Compared to the first time when they had to take care of the students, this time they advanced at full speed.
In just half an hour, the two arrived at the Outer Academy.
Without disturbing the students, Su Qian directly led Han Feng to a corner of the Outer Academy.
Han Feng glanced around.
"A space lock?"
Unlike the layout of the Inner Academy, the space here was more hidden and solid.
Su Qian formed a profound seal with his hand, and a blast of Dou Qi shot into the void.
A moment later, two echoes sounded from within the space.
Two figures, one grey and one white, instantly appeared on the open ground in front of Han Feng.
Their profound auras made the surrounding space fall silent.
"Elder Su Qian, what do you need from us?" the two elders, Qian and Bai, asked at the same time.
"Seniors, I have brought someone here. We wish to exchange for the seventh-tier water-attribute monster core in the Library Pavilion."
"A seventh-tier monster core?"
The voices of the two elders paused, and then they turned their gaze to Han Feng.
"And this is..."
"I am Han Feng. It is a pleasure to meet you both."
"Han Feng, are you the Medicine Emperor?" the two elders said in surprise.
"Yes."
The two elders looked at each other. The famous Medicine Emperor of the Black-Corner Region, why had he come to their Jia Nan Academy?
"Ahem, Seniors, Elder Han is now an elder of our Jia Nan Academy's Inner Academy. The reason for coming to exchange for the seventh-tier monster core is precisely because Elder Han is preparing to refine a seventh-grade pill."
The amount of information in this sentence was a bit overwhelming. The two elders took a long time to process and accept this fact.
"In that case, then you two may follow us."
The two elders said no more and worked together to open the space lock.
A huge, ancient library building finally appeared at the other end of the space, flickering in and out of view, and finally stood before them like a solid entity.
"We're here."
The two elders went upstairs first, and Su Qian signaled for Han Feng to follow.
"Elder Han, a seventh-tier monster core is extremely precious. What do you plan to exchange for it?"
Han Feng thought for a moment, then replied, "How about exchanging it for a sixth-grade pill?"
"Deal."
The two elders did not make things difficult and agreed after feeling that the value was about right.
The group went straight up to the ninth floor of the library. The two elders formed a seal and took out a treasure box from a hidden compartment.
Opening the treasure box, a seven-sided monster core was placed inside. Each edge emitted a faint blue light, and the rich water-attribute energy made the surrounding air a little moist.
"Elder Han, this is the seventh-tier water-attribute monster core."
Han Feng took the monster core from the hands of the two elders and nodded. "Many thanks, you two."
"This place is quite quiet. How about I refine the sixth-grade pill here?"
The two elders were silent for a moment, then said, "If Elder Han doesn't mind, we have no objection."
Han Feng smiled lightly and walked out of the Library Pavilion.
"Elder Su, you can go back first. I estimate I'll be here for another two days."
"Alright then. When you return to the Inner Academy, just let me know."
Su Qian tossed a jade slip to Han Feng and then turned to leave.
Watching Su Qian depart, Han Feng found a quiet spot and sat down cross-legged.
Taking out the three portions of ingredients for the "Six Jia Strength Recovery Pill" that he had gotten from Elder Hao, Han Feng started his cauldron to refine the pill.
The two elders secretly watched from the library tower.
"What do you think Han Feng came to our Jia Nan Academy for?"
"He's an alchemist. Could it be for the Fallen Heart Flame?"
A moment of silence.
"That thing has been getting more and more restless lately."
"It is a spiritual object of heaven and earth, after all. If we keep it confined, it will cause problems sooner or later."
"Hey? That's not right!" Qian Mu suddenly patted Bai Lie.
"Look, isn't that a Heavenly Flame?"
Bai Lie raised his eyebrows.
"It really is..."
"So, Han Feng isn't here for the Fallen Heart Flame?"
As everyone knew, Heavenly Flames would fight each other, so unless one possessed the supreme strength of a Saint or higher, it was impossible for one person to subdue two Heavenly Flames.
Doubt rose in their hearts again, but they were too lazy to think too much about things they couldn't figure out. Anyway, the task the headmaster had given them was to guard the Library Pavilion.
As for other matters in the academy, they didn't need to worry about them at all. They would only take action if the academy was on the verge of destruction.
It was rare for the two elders to see a seventh-grade alchemist refine a pill. Since Han Feng didn't mind, they just watched quietly.
"He really is skilled. His control over the flame is better than yours," Qian Mu remarked with emotion.
Just this flame control technique had already surpassed Bai Lie by a lot.
Bai Lie twitched his lips.
"I don't compete with alchemists."
"And he has a Heavenly Flame."
Qian Mu smiled and said nothing.
Time passed bit by bit. Han Feng used up all three portions of ingredients and refined three Six Jia Strength Recovery Pills.
The entire process was as smooth as flowing water, leaving the two elders stunned.
Was refining a sixth-grade pill that simple?
Why did it feel like Han Feng was just playing?
Before the Myriad Beasts Cauldron, Han Feng brought his hands together, absorbing all the energy phenomenon released by the sixth-grade pill.
A small, icy-crystal-colored lotus flower containing powerful energy was slowly born in the palm of his hand.
He was getting more and more skilled at this technique.
Han Feng stored it in the Green Lotus Sea Heart Flame. At this moment, several similar small energy lotus flowers were already floating inside.
One could imagine what a great destructive force would be created if these few streams of energy were to explode.
This was one of Han Feng's trump cards, and also a powerful means for him to deal with the three-colored Pill Lightning.
Putting the cauldron away in his storage ring, Han Feng came outside the library with the three sixth-grade pills.
Before Han Feng could knock on the door, the two elders came out.
"Elder Han, is the pill refined?"
Weren't you two watching the whole time...
Han Feng was slightly speechless in his heart. He took out a Six Jia Strength Recovery Pill.
"Yes, this is the Six Jia Strength Recovery Pill. It's a recovery-type pill that can also increase a cultivator's strength and defense, with no side effects."
The two elders took the pill and examined it carefully. They found that the color of the pill was excellent, and the pill patterns were profound. It was definitely a top-grade pill.
They had previously thought that Han Feng's refining was a bit crude, but now, seeing this, they had to admire the Medicine Emperor's alchemy skills.
"With this, the transaction is officially complete."
"Elder Han, you must be careful of the Pill Lightning when you refine a seventh-grade pill," Qian Mu reminded him, because with Han Feng's current Dou Emperor strength, he might not be able to withstand the Pill Lightning.
"The Pill Lightning is indeed dangerous. I wonder if you two seniors would be willing to lend a hand? I would be extremely grateful."
The two elders refused without even thinking.
"It's not that we won't help you, but we need to guard the Library Pavilion and cannot go out casually."
Han Feng nodded, preparing to take his leave.
However, at this moment, Bai Lie's voice sounded again, "But, if Elder Han were to refine the pill here, we could help a little."
Han Feng was taken aback, then said gratefully, "In that case, I will have to trouble you two seniors."
"It's no trouble, no trouble," the two elders said with a smile.
The opportunity to observe an alchemist refine a pill was truly rare. If Han Feng were to refine a seventh-grade pill here, they could also broaden their horizons.
However, the two elders would never have thought how much excitement this agreement would bring to their peaceful and stable lives.
