Chapter 377: Herbal Prescription Wall

"What exactly is going on?"

Mo Hongyi was on the verge of losing his mind. Teacher Liu, Master Teacher Zhang Xuan... weren't they the same damn person? And their students were fighting? What was the situation?

"Oh, you're really serious about this..."Seeing his complete unawareness, the teacher couldn't help but explain: "Several of Master Teacher Zhang Xuan's students, one of whom is named Zhao Ya, and Teacher Liu's student, Mu Xueqing, had an argument for some unknown reason. They've already fought once, and today was their second match..."The teacher quickly recounted everything he knew.

Upon understanding the situation, Mo Hongyi wore a strange expression, wanting to laugh but holding it back. A student in disguise fighting fiercely with his *own* student, with an almost endless intensity... Zhang Xuan must be internally collapsing right now.

"What does the Headmaster want with me?" he couldn't help but ask.

"The Headmaster's intention is simple: he wants to introduce Master Zhang and Teacher Liu, hoping they can resolve their differences with a smile. Since you're familiar with Teacher Liu, he wants you to act as a mediator!" the teacher explained.

"Me, a mediator? Persuading Teacher Liu and Master Zhang... to sit down and chat and eat together?" Mo Hongyi's expression became even stranger. "Are you kidding me? They are the same person. If Master Zhang appears, Teacher Liu can't. How can they sit together?"

"Alright then, go back and tell the Headmaster that I'll discuss this matter with Teacher Liu myself; you all don't need to worry about it..." Mo Hongyi said, suppressing his laughter. "Aren't you a genius who knows everything? I'd like to see how you handle this..."

After chatting for a while longer, Mo Hongyi headed towards Zhang Xuan's classroom.

"Yuan Tao, where are you going? Why didn't you call me?"Just as he left the room, he heard a hushed voice. Yuan Tao quickly turned around to see Zheng Yang standing nearby, smiling.

"I..." Yuan Tao hesitated.

"Alright, I know you're trying to cause trouble for that Teacher Liu. Let's go together!" Zheng Yang's eyes glinted.

"I'm afraid Master will blame us if he finds out..." Yuan Tao said. If he went alone, even if Master Zhang found out later, he'd at most get a beating. He was thick-skinned and not very afraid, but it would be bad if Zheng Yang got into trouble because of him.

"It's fine, we're good friends, good brothers. How can I let you take the blame alone?" Knowing his thoughts, Zheng Yang smiled. "However, to be honest, just the two of us probably won't be enough!"

"What do you mean?"

"It's simple. To drug Teacher Liu, we need to sneak into his classroom, right? And we need to find the vessel he drinks from to put the medicine in. Your defense is invincible, but you're too slow! I'm good at spear techniques, but my movement skills aren't great..." Zheng Yang chuckled. "Unless..."

"Wang Ying?" Yuan Tao understood his implication.

"Exactly. Let's call her. With her movement skills, she can definitely put the medicine into Teacher Liu's teapot without anyone knowing!" Zheng Yang said.

"Okay..."After thinking about it, Yuan Tao nodded, feeling there was no problem with what Zheng Yang said.It was easy to convince Wang Ying. Although the girl was a bit delicate and indecisive, as long as they found the right approach, she was easily swayed. And that approach was to seek revenge for Master Zhang! Teacher Liu's shameless favoritism was utterly despicable. Though Wang Ying didn't say much, she was also furious. So, upon hearing that she was needed to help drug him, she readily agreed after only a brief hesitation.

After their discussion, the three took advantage of the night to leave the mansion and head towards Tianwu Academy once more.

The night was quiet, and there weren't many students walking around the campus. After a brief inquiry, they found Teacher Liu's classroom.

"Looks like no one's here!"Pushing the door open and peeking inside, they saw no one, and their eyes lit up. They had expected to find students or Teacher Liu, but the classroom was empty. Zhang Xuan and Mu Xueqing had gone to the Alchemist Guild, and the other students had finished their training and left for the day. Lu Chong, who had been practicing here earlier, had already dragged his exhausted body back to his residence. Indeed, there was no one in the classroom at that moment.

They pushed the door open and went in. After searching for a while, they found the teacher's dedicated teapot and teacups.

"This is it. Put the medicine in!"The three nodded. Yuan Tao took out a jade bottle and poured all the powder inside. Unexpectedly, things went so smoothly. Just as they were about to leave, full of excitement, they heard the classroom door creak open.

The three jumped in fright. There was no time to escape now, so they quickly turned around.

"Is your Teacher Liu here?" a question was asked.

"Reporting, teacher, Teacher Liu is not here..." Hearing the question, and realizing it wasn't Liu Cheng, the three sighed in relief. Zheng Yang lowered his head and turned around.

"Not here? When he returns, tell him Teacher Sun Cheng visited!" the person outside said.

"Yes..." Zheng Yang quickly nodded.

"Hmm!" The visitor turned and left. After walking a short distance, he suddenly paused, wondering why the young man just now looked somewhat familiar, as if he had seen him somewhere before. "Never mind..." He thought for a long time but couldn't recall. Presuming it wasn't anyone important, he didn't linger and left directly.

"Let's go!"Seeing they hadn't been suspected, Zheng Yang and the others dared not stay. They hurriedly left the room and ran straight towards the mansion.

Sighing in relief, Zhang Xuan stretched. After a whole afternoon of effort, he had finally absorbed all the books from the Alchemist Guild into his mind. The exertion was immense, and he was utterly exhausted.

"Pure Yin Physique!"With a thought, dozens of books immediately appeared before his eyes. He casually opened one.

After reading for a while, his eyes lit up. Sure enough, there were records about the Pure Yin Physique.

"The Tier-4 Cold Yin Pill has a great effect on activating the Pure Yin Physique...""Cold Yin Pill?"

After finishing all the books on the Pure Yin Physique, he only found records of activation in two books, both mentioning the Cold Yin Pill. "The Cold Yin Pill, a Tier-4 medicinal pill, is refined from ingredients with extreme Yin and extreme cold properties, making it incredibly precious..."

He tried it out and knew that this medicine was indeed effective for the Pure Yin Physique, but Zhang Xuan began to worry again. There were no Tier-4 alchemists in Tianwu Kingdom, and naturally no Tier-4 pills. He would have to purchase it from headquarters, which, just like last time in Tianxuan Kingdom, would likely take at least several days. Zhao Ya and Mu Xueqing's duel was in three days, so there certainly wouldn't be enough time. Moreover, the most crucial point was... a Tier-3 pill had almost bankrupted him. A Tier-4 pill would undoubtedly be even more expensive; he probably couldn't even afford to buy it.

"If I had the pill formula, I could guide others to refine it..." A thought flashed through his mind. He couldn't refine pills himself, but he could guide others to do so. However, the prerequisite was having the formula. Otherwise, with countless medicinal ingredients in the world, just experimenting would be enough to exhaust someone to death...

"Cold Yin Pill formula!"With a thought, he searched through all the books in the library. Soon, his expression turned grim. The Alchemist Guild in Tianwu Kingdom, with so many collected books, actually didn't have the formula for this pill. He was puzzled for a moment, then suddenly realized. This was a Tier-4 pill; the strongest alchemist in this guild was only Tier-3. How could they possibly have it?

"Without the pill formula, I can't refine the pill... What should I do?" Zhang Xuan rubbed his temples. He couldn't possibly help Mu Xueqing improve her strength and not help Zhao Ya, could he? That wouldn't be competition; it would be a crushing defeat.

"Let's go out first and see." He pushed the door and walked out of the library. By then, it was already dark outside.

"Teacher Liu!" Alchemist Mu came forward to greet him. The other party was neglecting meals and sleep to help his daughter improve her strength, leaving him filled with gratitude.

"Alchemist Mu, who in our guild has a Tier-4 pill formula?" Zhang Xuan asked. Since the books didn't have the Tier-4 pill formula, perhaps some of these alchemists had private collections.

"A Tier-4 pill formula?" Alchemist Mu shook his head. "Our guild doesn't have a formula of that level. However, if you want one, you can apply to headquarters!"

"Apply to headquarters?" Zhang Xuan gave a bitter smile. "Wouldn't that take half a month for a round trip?"He knew that headquarters definitely had such a formula, but even the closest Xuanyuan Kingdom would take at least half a month to reach by flying savage beast. Even if he applied now, the formula wouldn't arrive for half a month; by then, it would be too late.

"Half a month? No need! Pills themselves are physical objects and must be delivered in person, which takes at least half a month... but the formula can directly appear on the Pill Formula Wall!" Alchemist Mu said with a smile.

"Pill Formula Wall?" Zhang Xuan was startled.

"That's right, it's somewhat similar to the Physician Guild's Difficulty Wall, connecting to headquarters. Alchemists who reach a certain rank can pay a certain price and request headquarters to grant them pill formulas or knowledge that is not too far above their current level, or difficult to understand!" Alchemist Mu explained.

"Oh!" Now knowing the name, Zhang Xuan quickly found relevant records in his books. The Pill Formula Wall was indeed as Alchemist Mu described, similar to the Physician Guild's Difficulty Wall, connecting to the main headquarters. As long as one paid the price, they could request the headquarters to transmit pill formulas or knowledge. However, to use this, one needed to be at least a Tier-3 alchemist. Even Alchemist Mu, a peak Tier-2 alchemist, was not qualified.

"Do I have to take the Tier-3 Alchemist examination?" Zhang Xuan hesitated. He wasn't worried about passing the alchemy examination, but everyone knew Master Zhang was skilled in alchemy. If he took the examination now, it would be easy to expose his identity and arouse suspicion.

"How many Tier-3 alchemists do we have in our guild?" he couldn't help but ask.

"The guild originally only had one Head, but recently, Alchemist Hongyun broke through and also reached that level. The highest level among the others is the same as mine, peak Tier-2, just a bit short of Tier-3. So... only the two of them are qualified to apply to the Pill Formula Wall." At this point, Alchemist Mu looked over, puzzled. "Teacher Liu, do you need a Tier-4 pill formula? But... even if you know the formula, it's useless if you can't refine it!"

"Alchemist Hongyun? Where is he? Take me to him!"Without answering Alchemist Mu, Zhang Xuan's eyes lit up upon hearing "Alchemist Hongyun." This was the arrogant fellow who had delivered the Yin-Breaking Pill back then, and Zhang Xuan had also seen him during the Master Teacher examination recently. He just hadn't expected him to have already broken through to the Tier-3 Alchemist realm. Since he was qualified to make the request, Zhang Xuan could simply ask for his help, thus avoiding the need to take the Tier-3 Alchemist examination himself and reducing unnecessary trouble.
