After waiting for over three hours, there was finally some movement from the secret passage. Elder Qin and Qin Ya both stared wide-eyed into the tunnel.

Then, they saw Chu Qingyun walk out, his steps light and unburdened.

"Young Master Chu, what was the result? Did you pass the test? Did you meet the senior?"

The moment Chu Qingyun emerged, Elder Qin couldn’t hold back and rushed forward to ask. He fired off three questions in a row, making Qin Ya, who was watching from the side, cover her mouth to stifle a giggle. She had never seen her grandfather so nervous.

Chu Qingyun smiled and said, "Fortunately, I managed to complete the mission and pass the senior’s test. However, that senior... he has already..."

Hearing this, a trace of sorrow flashed in Elder Qin’s eyes, but he quickly shook his head. "Actually, for that senior, this might not be a bad thing. You could even call it a release."

Chu Qingyun nodded in agreement.

A wisp of a Residual Soul, waiting alone for centuries in that sunless, underground Array... perhaps letting go of its lingering attachments and fading with the wind was indeed a form of release.

Watching the two of them speak in riddles, Qin Ya grew a little unhappy. "Hey, Chu Qingyun, what did you actually get down there? Being all mysterious..."

"Haha, speaking of which, Elder Qin, I wonder if you’ve ever heard of an Elixir called the Spiritual Longevity Pill," Chu Qingyun said with a smile.

Spiritual Longevity Pill!

Upon hearing the name, Elder Qin’s aged face suddenly flushed red. He was so agitated that his hands and feet began to tremble. "Young... Young Master Chu, could it be that you obtained the Pill Formula for the Spiritual Longevity Pill?"

Chu Qingyun nodded, walked to the table, and took out a brush and paper. On one sheet, he wrote down the names of more than twenty Spiritual Medicines.

After a moment’s thought, he picked up another sheet of paper and wrote down the Spiritual Medicines needed to refine the One Yang Pill as well.

Taking the paper with the ingredients for the Spiritual Longevity Pill, Elder Qin quickly scanned it. His brow furrowed tightly. "Young Master Chu, while the Spiritual Medicines for this Spiritual Longevity Pill are all Tier Three, several of them are extremely rare. I’m afraid my Ten Thousand Treasures Tower can only gather enough for two attempts at most. This... this will be difficult..."

As he said this, Elder Qin couldn’t help but sigh, his expression growing even gloomier.

The greater the hope, the greater the disappointment.

Alchemists have a high failure rate when Refining Elixirs. Furthermore, given his physical condition, he could no longer perform Alchemy himself. If a novice like Chu Qingyun were to try, the failure rate would likely be terrifyingly high.

With only two sets of ingredients, successfully forming a pill was practically impossible!

"Haha, rest assured, Elder Qin. Two sets of ingredients will be more than enough," Chu Qingyun said with a confident laugh.

Although he had obtained the senior’s lifetime of knowledge, including all sorts of Alchemy experience, in terms of practical skill, he was still a complete rookie. After all, someone else’s experience could only serve as a reference; it was ultimately theirs, not his own.

It was like a master teaching an apprentice, relaying every piece of their experience, but without practice, the apprentice would still know nothing.

However, Chu Qingyun was very confident.

Because on his way back, he had thought of a trump card.

And that was... the Light Card!

Chu Qingyun had obtained a Light Card from the Great Xia Dragon Guard’s Illusion Realm trial. Inside that Light Card, he could simulate all sorts of things he had seen before.

Before, Chu Qingyun had always felt that besides being a toy to mess around with when he was bored, the Light Card had no other use.

But just now, as he was walking out of the secret passage, he suddenly realized something. He could use the Light Card to practice Alchemy, using Spiritual Medicines and a Pill Furnace simulated by the Illusion Realm.

The rules inside the Light Card were the same as in the real world anyway. As long as he learned it in the Illusion Realm, it was equivalent to learning it in reality.

And no matter how many times he failed inside, there wouldn’t be the slightest loss!

Alchemists are rare, and powerful, High Grade Alchemists are even rarer. This is because being an Alchemist is an incredibly, incredibly expensive profession!

To accumulate Alchemy experience, improve one’s Alchemy skills, or learn new Pill Formulas, massive amounts of practice are indispensable.

Massive amounts of practice mean massive amounts of failure, wasting vast quantities of Spiritual Medicines and other Celestial and Earthly Treasures. And the higher the grade, the more waste is produced.

One could say that every successful Alchemist has risen from the ashes of countless Celestial and Earthly Treasures.

But with the help of the Light Card, Chu Qingyun could completely avoid such losses!

Moreover, one day inside the Light Card was only one hour in the real world. This would save him a great deal of time on the Alchemy Dao, preventing it from interfering with his progress on the Martial Dao.

It was killing two birds with one stone!

Faced with Chu Qingyun’s confidence, Elder Qin was still a little worried and asked one more time, "Young Master Chu, are you truly confident you can refine the Spiritual Longevity Pill with just two sets of ingredients?"

"I’m 90% certain!" Chu Qingyun replied.

"Good! Ya, go and fetch the Spiritual Medicines on these two lists. For the Spiritual Longevity Pill materials, gather as many sets as you possibly can. As for the One Yang Pill... bring ten sets for now!"

Elder Qin said, handing both pieces of paper to Qin Ya.

Even though he still had some doubts about a novice like Chu Qingyun, Elder Qin was willing to trust the senior’s judgment. ’Having received that senior’s inheritance, perhaps Chu Qingyun really does have some extraordinary qualities.’

Besides, he had no other choice now but to believe in Chu Qingyun.

Qin Ya was a bit reluctant to fetch the Spiritual Medicines. She grumbled, "What’s the big deal? It’s just getting some Spiritual Medicine. Can’t you just order the servants to do it..."

In response, Elder Qin just smiled and said, "The Spiritual Longevity Pill is a Spirit Level Elixir. When consumed by a Martial Spirit Realm expert, it can increase their lifespan by one hundred years."

Hearing this, Qin Ya froze on the spot, her small mouth slowly forming an "O" shape.

"I’ll go get the Spiritual Medicines right away! You guys wait here!"

"I’ll be back in a flash!"

Before her voice had even faded, Qin Ya had already dashed out in a hurry.

Chu Qingyun and Elder Qin both smiled and sat down.

"Elder Qin, there’s one more thing I’d like to ask you. I was wondering how many Tier Four Spiritual Medicines your Ten Thousand Treasures Tower might have?" Chu Qingyun hesitated for a moment but asked anyway.

Although Chu Qingyun had not yet obtained the Secret Techniques for the Fourth Layer and Fifth Layer of the Profound Celestial Divine Pattern, he already knew that cultivating these two layers would require Tier Four Spiritual Medicines!

Going from Tier Three to Tier Four might seem like just one step up, but that single step represented a qualitative change.

In this regard, it was the same for Spiritual Medicines as it was for Martial Souls.
