Lin Feng stood up and nodded solemnly.
Using too much dark magic would erode the soul. Lin Feng would not use dark magic extensively until his soul strength reached a satisfactory level.
Besides, with his current strength, did he even need to use dark magic?
Hesitating for a moment, Lin Feng took out two small, capped test tubes.
Inside them was a liquid that emitted a green fluorescent glow.
Although he had only been studying at Kamar-Taj for a few days, Lin Feng's gains were incredibly substantial.
"Sorcerer, thank you for your care these past few days."
"This is for you. I'm leaving!"
Placing the test tubes on the table, Lin Feng departed Kamar-Taj and soared into the sky...
Watching Lin Feng fly away, the Ancient One thought to herself, wishing that Lin Feng had truly taken her words to heart...
After Lin Feng left, the Ancient One curiously picked up the items he had left on the table.
They were a vivid green, yet they captivated her gaze.
She didn't know what these things were, but her intuition told her they were extraordinary.
With a sudden impulse, the Ancient One uncorked one of the bottles.
Instantly, an incredibly potent life force erupted from the bottle.
"I..." The Ancient One exclaimed in shock, quickly resealing the cap, barely refraining from a curse.
In all her long life, she had never encountered anything so brimming with vitality!
Even with the cap secured, some scattered luminous particles still lingered in the air.
As these particles settled on the Ancient One's small wooden table, the surface seemed to come alive, sprouting tiny branches that grew at a visible rate.
Fortunately, the growth eventually stopped.
The Ancient One looked at the now branch-covered table with a mix of amusement and disbelief, carefully putting away the two small bottles of liquid.
She hadn't expected Lin Feng to give such a precious gift.
The Ancient One surmised that these substances likely came from the same origin as the tea Lin Feng had given her, but the sheer density of life force was astonishing.
She suspected that a single bottle might be enough to revive the dead.
In any case, it was undoubtedly a treasure...
The Ancient One felt a deep sense of relief. It was good to have made his acquaintance.
High in the sky, Lin Feng was flying home.
He wasn't using his own flight abilities but rather his Cloak of Levitation to carry him.
Since he intended to use magic frequently, Lin Feng had chosen this magical artifact to let it have some exercise.
This Cloak of Levitation, acquired during his first visit to the Zombie Universe, was capable of covering an entire solar system's eyesore after being infused with enough energy.
After leaving the Zombie Universe, the Cloak of Levitation had transformed into a decorative fabric, always affixed to his Superman bracers.
The cloak, excited, flew Lin Feng about haphazardly in the air.
For such a long time, Lin Feng hadn't used it, and it had complained to him more than once.
But there was nothing it could do. Its master was too powerful, flying faster than it could, and infinitely superior in both offense and defense.
Therefore, in ordinary times, it could only venture out for a stroll. Its ability to assist Lin Feng was practically nil.
...
Flying on one's own and being carried by another offered entirely different experiences. Lin Feng reveled in the freedom.
However, as he flew, Lin Feng began to ponder, stroking his chin.
He mused over the words "Cloak of Levitation," feeling as though he was on the verge of recalling something, yet it remained elusive... a strange sensation.
"Cloak, do you know how to increase soul strength?" Lin Feng casually asked, not expecting an answer.
As predicted, the Cloak conveyed its consciousness: [Unknown...]
To think it was the comic book version of the Cloak of Levitation and didn't know this!
However, Lin Feng didn't intend to burden the Cloak and merely murmured to himself.
He wondered if the Ancient One had held anything back. The library contained very little on soul magic, or perhaps the application of soul magic was inherently rare in the world?
Lin Feng searched his memories with a troubled mind, looking for any lingering traces of magic in the Marvel universe that he could explore.
At this moment, the Cloak's consciousness transmitted again.
[Master wishes to increase soul strength?]
"That's right!" Lin Feng replied casually.
"But I've already read through the entire library at Kamar-Taj, and I haven't found any direct and quick methods..."
The Cloak knew of Kamar-Taj and even the Ancient One. However, Lin Feng had asked it, and it stated that it didn't know Stephen Strange, and Lin Feng was its first master.
[While I don't know how to increase soul strength, you've finished the library at Kamar-Taj. Can't you visit other libraries?]
The Cloak's thought process was simple, but Lin Feng could only offer a wry smile.
"I wish I knew where else I could find books on magic."
Magic was something Lin Feng had only recently begun to explore. It was not impossible for magical races to exist in the universe.
However, to be truly useful to Lin Feng, their magic would need to be powerful enough to evade his perception.
For those magical races that Lin Feng could find with a single glance, those incapable of even shielding themselves from scrutiny, he doubted they would possess what he sought.
"Wait a minute..."
Lin Feng suddenly slammed on the brakes mid-air.
"Good heavens, how could I have forgotten that?"
He recalled the fleeting thought he'd just had.
Yes, if he had finished one library, why not visit another?
Lin Feng had indeed thought of such a place.
The Lost Library!
Damn it, he had fought alongside a corrupted Stephen Strange and the Ultimate Watcher against the Infinity Ultron, how could he have almost forgotten about the Dark Doctor Strange?
That fellow had been to the Lost Library.
The Lost Library of Kamar-Taj, a legendary library said to contain all books.
It was there that the Dark Doctor Strange had acquired the power to alter absolute points in time.
But ultimately, the Dark Doctor Strange was too weak. Although he revived his girlfriend, the world collapsed in an instant, and his girlfriend was lost again.
"Cloak, do you know where the Lost Library is?"
[Unknown...]
Lin Feng rolled his eyes. Useless, he knew nothing.
However, he hadn't expected the Cloak to know.
In Lin Feng's memory, after the battle with Infinity Ultron, the Dark Doctor Strange seemed to have remained on Earth in that universe for a period.
This... Lin Feng was always a man of action.
Once this idea struck him, he couldn't shake it.
With a snap of his fingers, he opened a portal to the universe where the Dark Doctor Strange resided.
However, Lin Feng didn't immediately step through, pausing at the threshold.
[What is it?] the Cloak inquired.
"Nothing..." Lin Feng waved his hand somewhat awkwardly, dismissing the portal.
Then, putting on his Sling Ring, he drew circles in the air and reopened the portal...
