After waiting for a while, no guards broke in.
The guards at the door seemed to have noticed nothing unusual and remained motionless.
Without a doubt, Lin Feng had directly severed all communication between the entire room and the outside world.
Elder Zhang sighed, "It seems that's the case..."
"Little one, you've come to see me late at night. Is there something you need?"
"Do you have any regrets left in this world?"
As expected of Elder Zhang.
A normal person seeing Lin Feng, who looked like a soul, would have screamed their lungs out, if not wet themselves.
Yet, Elder Zhang so quickly accepted the existence of a soul that should only appear in novels and movies.
But... what was with "little one"?
Hearing this title, Lin Feng's eye twitched uncontrollably.
But thinking about Elder Zhang's age... alright, in front of him, Lin Feng was indeed a child...
However, Elder Zhang clearly mistook Lin Feng for a vengeful spirit...
Lin Feng looked at his translucent body.
It wasn't strange to have such a thought... It seemed Elder Zhang had conjured a scenario of a wronged soul unwilling to reincarnate, wanting to go straight to heaven to appeal his case...
Lin Feng stared at Elder Zhang, speechless.
Elder Zhang's aged face wore a smile, his eyes gentle.
Even if it were a ghost, it was an Eastern ghost! Elder Zhang, having calmed down, had nothing to fear!
After all, they were all children of the Yanhuang Great Land...
As for why Lin Feng came, it was naturally to deliver a grand gift.
However, actions always spoke louder than words.
Under Elder Zhang's puzzled gaze, the semi-transparent Lin Feng flipped his hand and produced a syringe.
He quickly floated to Elder Zhang's side and, with swift movements, plunged it into Elder Zhang's artery.
"I'm here... to give you an injection, Elder Zhang!"
The green liquid was slowly injected into Elder Zhang's body.
Elder Zhang's eyes widened instantly. He felt a scorching, lava-like liquid flow through his meridians and blood vessels, reaching every limb and extremity.
Was this little ghost trying to harm him?
Before he could think further, Elder Zhang lost consciousness almost immediately under the effect of the potion.
A bio-force field enveloped Elder Zhang, helping to streamline and strengthen the energy flow.
What Lin Feng injected him with was an improved version of the Super Soldier Serum.
Extracted from the Super Soldier Serum, it was even more potent and stable.
Even ordinary people could use it.
It could repair genetic defects and continuously strengthen the body.
The reason for doing this was that Elder Zhang could not falter, and also to quickly prove the authenticity of what Lin Feng was about to present.
Without presenting something tangible, it would be hard to gain anyone's trust!
The Super Soldier Serum's enhancement was comprehensive. Among the materials Lin Feng brought, there was the complete manufacturing method for the improved Super Soldier Serum.
However, the cost to produce even one dose of such an agent would likely be astronomical.
With Lin Feng's assistance, it only took an hour for the Super Soldier Serum to comprehensively enhance Elder Zhang's body.
His pale hair regained its black luster.
The lines on his face, etched by day and night labor, receded, restoring Elder Zhang's vigorous appearance from his middle age.
After an unreasonably potent enhancement, both his bones and flesh reached peaks previously unattainable by humans.
It was estimated that even bullets could no longer penetrate Elder Zhang's skin.
The enhancement concluded quickly, and Elder Zhang also slowly regained consciousness.
"Elder Zhang, please look!"
To avoid any unnecessary misunderstandings, Lin Feng directly produced a full-length mirror, about a person tall, and placed it in front of Elder Zhang.
Before Elder Zhang could even process what had happened, he stared in astonishment at the familiar yet unfamiliar figure in the mirror.
Gradually, an incredulous light ignited in Elder Zhang's eyes.
He looked at the person in the mirror and instinctively touched his hair.
The person in the mirror mirrored his action.
Without a doubt, this was himself! No, it was himself from twenty years ago!
"This... is me?"
Elder Zhang slowly clenched his fists in disbelief.
A grinding sound of bones echoed.
Incredible!
The old injuries that constantly plagued him had inexplicably vanished!
What was this surge of power?
And this incredibly clear mind...
Elder Zhang subconsciously gripped the metal armrest of his chair.
Screech...
A teeth-grinding sound of metal deforming followed.
The metal armrest was easily crushed into a ball by his grip.
"This..."
Elder Zhang was utterly shocked.
The scene before him completely defied his understanding!
With this single feat, he could probably bend a cannon barrel!
"Incredible..." Elder Zhang murmured to himself.
A method of returning to youth, like that of an immortal?
No, it was an even more preposterous, comprehensive enhancement! Even in his youth, he couldn't crush metal into a ball!
Truly incredible, this was simply supernatural power!
"Was it that injection?" Elder Zhang instantly thought of the substance Lin Feng had injected into him.
He turned to meet Lin Feng's gaze.
Lin Feng nodded his affirmation.
It really was...
Elder Zhang's gaze softened with relief.
A misunderstanding, a misunderstanding.
So, the little one wasn't trying to harm him...
"I apologize, Elder Zhang."
"I injected you with the Super Soldier Serum without your consent."
"But doing so was necessary to make you believe what I'm about to say..."
Lin Feng began with an apology.
While no one would refuse to become younger and stronger, Lin Feng's act of injecting him without permission was indeed somewhat improper.
In Eastern terms, it had a slight hint of rebellion.
But from Lin Feng's perspective, this approach was not without its merits.
The real world was different from novels. If Lin Feng had just casually produced a syringe and claimed it could turn someone into a superhero, no one, not even a ghost, would believe him!
Let alone expect Elder Zhang to believe and inject himself with it.
Even if Elder Zhang harbored a sliver of doubt and had scientists verify the serum,
He was sorry... with current scientific capabilities, they wouldn't understand it!
"It's alright, little one. Rather, I should be thanking you!" Elder Zhang still had a kind smile, showing no anger at Lin Feng's actions.
This injection was too miraculous. Feeling the surge of power within him, Elder Zhang had no doubt that even if he were sent to the battlefield now, he could fight a hundred men.
Although Lin Feng's actions were somewhat unconventional, it was clear they were well-intentioned.
This was goodwill from a fellow countryman! Would Elder Zhang quibble over it? What a joke!
"Now, can you tell me your purpose?" Elder Zhang asked immediately.
First, he appeared in his room, and then he injected him with an unknown and powerful serum.
Elder Zhang had a premonition that what Lin Feng was about to say would be information with explosive, nuclear-like impact.
