In the early stages of cultivation, breakthroughs didn't take long to stabilize. But as the process progressed, the time required gradually increased. Once someone reached the Immortal King Realm, a single breakthrough could take anywhere from ten days to half a month.

Since he still had some time, Liu Wuxie took out the alchemy cauldron. The Heavenly Dao Book had warned him about it, so he believed the cauldron possessed something special.

Ye Linghan leaned closer, unable to understand why Liu Wuxie had purchased a damaged cauldron.

Liu Wuxie activated Ghost Pupil and probed deep into the cauldron, but he failed to find anything unusual.

"The artifact and pill runes are bizarre. They might look simple, but their arrangement is vastly different from ordinary pill cauldrons!" Liu Wuxie reached this conclusion after carefully inspecting the cauldron.

"This is just an ordinary cauldron. Is there a need for you to examine it so carefully?" Ye Linghan asked.

She felt a little hungry, and since beasts rarely appeared at this hour, she descended the mountain to look for food.

Liu Wuxie refused to give up. He summoned a black hole and swallowed the alchemy cauldron into the Sky Devouring Divine Cauldron. The instant the alchemy cauldron entered, demonic flames surged out and wrapped around the entire cauldron.

As time passed, the alchemy cauldron's surface began to redden, creating an extremely bizarre sight. The runes engraved on the cauldron seemed to come alive as they started overlapping with one another.

The entire process lasted around fifteen minutes before the runes condensed into lines of text that hovered before Liu Wuxie's eyes.

"This..." Liu Wuxie was stunned to discover such a great secret inside the alchemy cauldron. He finally understood why the Heavenly Dao Book had reacted.

The lines of text hovered in midair before turning into streams of golden light that burrowed into Liu Wuxie's mind. He immediately shut his eyes and began comprehending the text.

"Heavenly Destiny Alchemy Art!" Four large characters first appeared in Liu Wuxie's mind, serving as the general outline of the text. It turned out to be a profound alchemy technique that Liu Wuxie had never heard of, even after searching his memories.

While Liu Wuxie did not claim to be the greatest alchemist in the celestial realm, he was confident that his skills ranked among the top ten. Yet even so, this alchemy technique was far more exquisite and profound than anything he had mastered in his previous life.

Most importantly, pills refined through this technique would contain an aura of heavenly destiny. In other words, every pill produced through this technique would seize the blessings of heaven and earth. The technique drew energy from heaven and earth to form pills, and Liu Wuxie could hardly believe such a heaven-defying alchemy technique existed.

He had found this alchemy technique at the perfect time. He did not dare to use any technique connected to his previous life. Producing low-grade pills was still fine, but once he started refining high-grade pills, he would inevitably have to rely on the alchemy techniques from his previous life. If someone were observant enough to examine those pills, they would identify him.

With the Heavenly Destiny Alchemy Art, however, he no longer had to worry about that. More importantly, it was even more exquisite than the alchemy techniques he had mastered as an immortal emperor in his previous life.

"What a profound alchemy technique! It has combined the essence of heavenly dao, destiny, creation, and various others into one." Liu Wuxie murmured. He needed time to digest it, as the text contained over ten thousand characters. But with the Heavenly Dao Book, he could break it down rapidly.

The cauldron once again appeared ordinary after flying out of the Sky Devouring Divine Cauldron. The runes on it had also gone back to normal. The most valuable thing about this cauldron was the Heavenly Destiny Alchemy Art.

Over the years, this pill cauldron had passed through the hands of countless alchemists, yet none of them had discovered its secret. The Sky Devouring Divine Cauldron could devour and refine everything in the world, allowing Liu Wuxie to uncover the cauldron's hidden secret. Otherwise, even the True Samadhi Fire would not have been able to make the characters appear.

When Ye Linghan returned, she found Liu Wuxie meditating and did not disturb him. She built a bonfire and roasted the wild animals she had caught over it as the aroma of roasted meat drifted through the air.

Liu Wuxie only opened his eyes after two hours. By then, he had grasped the essence of the Heavenly Destiny Alchemy Art. If someone else had been in his position, they might not have digested the entire technique even after three to five years.

"Smells good!" Liu Wuxie woke to the mouthwatering aroma, or he would have continued comprehending the alchemy technique for a while longer. He had not eaten dinner, and hunger had already set in.

"What were you thinking about earlier?" Ye Linghan asked, tearing off a piece of meat and handing it to Liu Wuxie. When she had returned, she had noticed a faint rhythmic fluctuation coming from his body. 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

"Thinking about tomorrow's lesson," Liu Wuxie said, brushing the matter aside. For now, he had no intention of telling anyone about the Heavenly Destiny Alchemy Art. It wasn't that he distrusted Ye Linghan, but knowing about it would bring her no benefit.

Ye Linghan possessed the Mystic Yin Physique, meaning she had been unable to practice alchemy since birth.

"That was what I'm thinking too. I plan to teach them about spiritual arrays and guide them in their cultivation tomorrow," Ye Linghan said, swallowing the meat in her mouth as she shared her thoughts.

"That works," Liu Wuxie replied. He had no objection, since Ye Linghan was the mentor while he was merely an assistant.

"I'll guide them in their cultivation, while you teach them spiritual arrays. This way, we can split our workload into two. What do you think about that?" Ye Linghan asked. She knew she could not compare to Liu Wuxie in spiritual arrays, but she still had the right to speak on cultivation. After all, she was in the Profound Immortal Realm.

"That works too," Liu Wuxie replied.

His indifferent answer angered Ye Linghan. She threw the unfinished meat at him, stood up, and left in a huff. She did not want to remain with Liu Wuxie for another moment.

"I'll return first. You can bring them back tomorrow," Ye Linghan said. She rushed back to the Azure Flame Dao Hall overnight, leaving Liu Wuxie alone.

Liu Wuxie looked at Ye Linghan's fading silhouette, then at the unfinished meat on the ground, his face full of innocence.

"Women are really barbaric," Liu Wuxie said. He went back to gnawing the meat. His mood was excellent. Not only had he reached the High Immortal Realm, but he had also obtained the Heavenly Destiny Alchemy Art.

When the sun rose in the east, a new day arrived. After meditating through the night, Liu Wuxie had further refined his cultivation.

Relying on his footwork, he headed down the mountain in a flash.

Xiao Qian and Shi Wa had not slept all night. Both siblings were excited, and their parents were already standing outside the door.

"Have you both packed?" Liu Wuxie asked.

The siblings had only packed a small bag each. Aside from a few changes of clothes, they brought little else.

"We've finished packing," Shi Wa replied nervously. He still felt as if he were dreaming.

"Come with me then," Liu Wuxie said.

After today's farewell, the siblings would be separated from their parents by the gulf between mortals and immortals.

"Father, Mother, take care of yourselves," Shi Wa said, dropping to his knees and kowtowing to them.

Xiao Qian also sobbed, reluctant to part from them.

"Go on. Don't worry about us," the old couple said, waving the siblings farewell.

After Shi Wa kowtowed, he rose to his feet and silently followed Liu Wuxie. When they returned to Eastern Emperor City, Liu Wuxie took them to buy some necessities before heading back to the Azure Flame Dao Hall.

By the time they returned, Ye Linghan had already prepared everything, and the entire courtyard looked brand new. It turned out that she had returned early the previous night to tidy up the courtyard. The weeds were gone, and they had cleared away all the miscellaneous items piled around the area.

"There's an empty room over there, where Xiao Qian can stay. As for Shi Wa, you'll stay with me," Liu Wuxie said. He let Xiao Qian have a room to herself while Shi Wa would have to squeeze in with him.

After all, the courtyard had only three rooms, and this arrangement was reasonable. Xiao Qian was a girl, so it would be inconvenient for her to share a room with her brother.

As for Ye Linghan's room, it was so crowded with her belongings that nothing else could fit inside.

"Teacher, I can just stay in this small room with my brother," Xiao Qian said, walking toward a small room used for storing miscellaneous items.

"From this moment on, you two will listen to everything I say," Liu Wuxie said, his tone turning much stricter.

"Listen to him," Ye Linghan replied. She had no idea why Liu Wuxie was already losing his temper so early in the morning.

Then again, the celestial realm was far crueler than they imagined, and Liu Wuxie did not want to watch them die before him. If they wanted to survive, they had to give everything they had to cultivate.

Shi Wa placed his belongings in Liu Wuxie's room before walking back into the courtyard. Xiao Qian also set down her things in her room before coming out and standing beside her brother.

At that moment, Xiang Rulong and the other students arrived one after another. After Liu Wuxie took the head count, he noticed that five people were missing, leaving only seventeen students in the class. Those five had likely regretted their decision and given up on joining Liu Wuxie's class.

"Mentor, do we go to the classroom?" Xiang Rulong asked.

"We won't be using the classroom today. We're going to the seaside," Liu Wuxie replied. His class never followed conventional methods.

Most students spent their time in classrooms and went outdoors only occasionally.

Ye Linghan was confused and could not understand Liu Wuxie's intentions. With no other choice, she could only follow them.

The group passed through layers of courtyards, drawing the attention of many students.

"Look! Why are they heading toward the sea?" Most classrooms had windows, allowing the students to see Xiang Rulong and the others passing by.

Many mentors cursed, "This is ridiculous! He's taking students outside instead of teaching them. Let's see how he handles it when their elders complain!"

The students had spent considerable resources studying at the Azure Flame Dao Hall. If they failed to learn anything, their elders would surely question the Dao Hall's teaching standards, and that would ultimately affect the mentors' reputations as well.

"Go notify the upper echelons. I want to see what that brat is trying to do now," Nangong Shan said to his assistant when the group passed by the blacksmithing class.

Liu Wuxie ignored the voices around him. He could already hear waves crashing against reefs up ahead, and a refreshing sea breeze blew toward them.

"Everyone, stand in a row," Liu Wuxie said to the seventeen students.

"My teaching method is different from others, and you still have time to back out if you regret joining my class. But if you choose to stay, you'll have to listen to my orders without hesitation or objection," Liu Wuxie said, giving them one final chance to withdraw.

"Mentor Liu, what will we be learning today?" Zhang Dashan asked.

Unlike other classes, where mentors handed out lesson plans to students in advance, Liu Wuxie had no plan at all and had brought them to the seaside instead.
