Although this alchemy manual was not the original, but a copy made by Jiang Lingxuan herself, its contents were exactly the same as the original manual.

After looking through it for a while, Ye Feng's face lit up with joy.

“I’ve got it, I know what to do,” Night Wind said with a smile.

The night passed quickly.

At dawn, the night wind flew towards the alchemy workshop and arrived at its gate in no time.

Just as the night breeze subsided, Wang Geling strode out of the alchemy workshop with a radiant smile.

"Junior brother, you've finally arrived! I've been waiting for you for quite a while," Wang Geling said with a smile.

"Is Elder Wang Tianyi at the alchemy workshop?" Ye Feng asked.

"My master is here, come with me."

After Wang Geling finished speaking, she led the way, while Ye Feng followed behind Wang Tianyi and strode into the alchemy workshop, passing through the main hall and heading towards the alchemy room where Wang Tianyi was.

Upon reaching the door, Wang Geling respectfully said, "Master, Junior Brother Ye has arrived."

"Please let him in," Wang Tianyi's voice came from the alchemy room.

"yes."

After Wang Geling responded, she said to Ye Feng, "Go in quickly, junior brother, my master is waiting for you."

"Okay, thank you for leading the way, senior sister."

Ye Feng pushed open the door to the alchemy room and strode inside, while Wang Geling did not enter and closed the door behind her.

So now only Ye Feng and Wang Tianyi are in the alchemy room.

Wang Tianyi sat cross-legged on the futon as usual, her expression serene.

Ye Feng walked up to Wang Tianyi and bowed. Wang Tianyi slowly opened her eyes and raised her hand to cast a restriction.

Once the restriction was activated, it immediately sealed off the entire alchemy room.

In this way, no matter what happens inside the alchemy room, people outside will hardly notice.

"Senior Sister said that Elder Wang wants to have a deeper conversation with me. I wonder what you want to discuss?" Ye Feng asked, feigning curiosity.

"Naturally, it's the art of alchemy," Wang Tianyi said calmly.

Night Breeze smiled and said, "Then Elder Wang, please ask whatever you want to know, and I will answer to the best of my knowledge."

"Please sit down."

Wang Tianyi pointed to the prayer mat in front of her.

Ye Feng didn't stand on ceremony and immediately sat down cross-legged on the futon.

Wang Tianyi then continued, "Ye Feng, I heard from Ge Ling that you refined six Ice Spirit Protective Pills in one batch at the Pill Workshop yesterday?"

“Exactly.” Night Breeze nodded.

"And you even broke through to the True Essence Realm while refining pills?" Wang Tianyi asked again.

"That's true, but it was extremely lucky. At that time, my true energy was running out, and I was about to fail. I don't know what happened, but I inexplicably broke through to the True Essence Realm. Perhaps it was all preordained. Heaven didn't want to see those junior sisters perish, so it helped me and used my hand to save them," Ye Feng said with emotion.

“But this is too much of a coincidence. And even if you have broken through to the True Essence Realm, to produce six pills in one batch, and six of them are Grade 7 spiritual pills, is really surprising to me. To be honest, even I cannot produce six Grade 7 spiritual pills in one batch.” Wang Tianyi shook her head and said.

After a pause, Wang Tianyi continued, "So now I'm very curious, and I'd like to ask you how you managed to refine seven Grade 7 spirit pills in one go with your True Essence Realm strength? After all, Grade 7 spirit pills are already high-grade spirit pills, and they are definitely not comparable to Grade 3, 4, or even 5 pills."

"So that's what Elder Wang is curious about."

Ye Feng smiled and continued, "Elder Wang, this actually involves one of my secret techniques."

"Secret technique?" Wang Tianyi's expression became even more curious.

“That’s right. This secret technique is a very special alchemy method called the Seven Apertures Exquisite Alchemy Method. Using this secret method, you can refine up to seven spirit pills at once,” Ye Feng replied.

"Tell me in detail," Wang Tianyi said, staring intently at Ye Feng.

Ye Feng continued, "This alchemy method places extremely high demands on alchemists. They must have mastered the control of their true qi to a highly refined level. If their control of true qi is not exquisite enough, they are simply not qualified to learn or practice this alchemy method."

"Therefore, the demanding requirements are the first difficulty of the Seven Apertures Exquisite Alchemy Method."

Wang Tianyi laughed and said, "The first difficulty? It seems that this alchemy method has more than one difficulty."

"Exactly."

Ye Feng smiled slightly and continued, "The second difficulty is the medicinal herbs."

"The Seven Apertures Exquisite Alchemy Method can refine multiple spiritual pills at once, but it consumes a great deal of medicinal materials. Simply put, it requires double or even more medicinal materials."

“Yesterday, when I was refining the Ice Spirit Protecting Meridian Pill, I asked Senior Sister Wang to prepare enough medicinal materials to make fourteen or even fifteen pills, but in the end I only managed to refine six. So this is the second difficulty of the Seven Aperture Exquisite Pill Refining Method.”

Wang Tianyi thought for a moment and nodded slightly.

After emerging from seclusion yesterday, Wang Tianyi heard about Ye Feng's success in refining six seventh-grade spirit pills in one batch. She felt something was amiss and specifically asked Wang Geling about it in detail.

Wang Geling later mentioned how many medicinal herbs Ye Feng had requested, and at that time Wang Tianyi had already realized that the amount of medicinal herbs Ye Feng had requested exceeded the amount needed to refine six Ice Spirit Protective Pulse Pills.

However, the Lingshui Clan was large and wealthy, with abundant reserves and no shortage of medicinal herbs, so Wang Tianyi did not care.

Moreover, when Wang Tianyi refines pills, she usually prepares one or two extra portions, since there is a chance of failure in pill refining, and even she cannot achieve 100% success.

If the process fails, the medicinal materials will naturally be destroyed. It is necessary to have extra medicinal materials in reserve to ensure that the process can continue after a failure.

Hearing Ye Feng say this, Wang Tianyi finally understood that Ye Feng's request for so many medicinal herbs was not for this purpose, but because the special alchemy method he mentioned required even more medicinal herbs.

"Is there a third difficulty?" Wang Tianyi asked again.

Ye Feng nodded and said, "Yes, the 'seven' in the Seven Apertures Exquisite Alchemy Method not only refers to the maximum number of spirit pills that can be refined at once, but also to the highest grade of spirit pills that can be refined. Fortunately, the Ice Spirit Protective Meridian Pill I refined yesterday was a grade seven spirit pill, which is why I was able to refine it using the Seven Apertures Exquisite Alchemy Method. If it were a grade eight or nine spirit pill, not only would my strength be insufficient, but the Seven Apertures Exquisite Alchemy Method would also be unable to refine it."

"These three difficulties mean that although the Seven Apertures Exquisite Alchemy Method is useful, it also has many drawbacks. Therefore, I don't usually use this method to refine pills very often. It was only yesterday's emergency that forced me to use this method. Fortunately, I was lucky and succeeded on the first try; otherwise, I would have wasted even more medicinal materials," Ye Feng said earnestly.
