Here's a polished and fluid version of your story:

Manav entered the dockyard and walked all the way back to the spot where he had met Gwen two weeks ago. After inspecting the area to ensure no one was around, he took out his stone pickaxe and started mining iron.
Tak
Tak
Crack
Using the stone pickaxe, mining iron was smooth but slow—three blocks per hour. However, mining took its toll on him, and he had to rest for 10-15 minutes after every two blocks, decreasing his efficiency.
The sun was high in the sky, and far off, a blonde girl swung between buildings using her web-slingers, humming a tune.
"Hey, gimme some cash!" a thug threatened an old woman in a nearby alley, waving a knife. Passersby ignored the commotion, pretending not to hear.
"Hey, man. Threatening old ladies? Not cool. Why don't you audition as a thug in movies? At least you'd make some money." A female voice echoed behind the thug.
"I tried!" the thug replied instinctively. "But I failed every audition, so here I am."
"Wow, you couldn't even land a thug role? That's rough. Maybe jail will be more suited for you."
The thug turned and slashed at the voice, only to miss as Ghost Spider dodged effortlessly and shot webs at his hands, binding them together.
"Well, off to meet your new family of thugs in jail. Bye!" she quipped before swinging away as police sirens grew louder in the distance.

High above the city, Ghost Spider swung toward her makeshift base at the dockyard.
"Ugh, I need to finish my high school assignments," she muttered to herself. "And Daredevil won't let me anywhere near Hell's Kitchen. Says it's his territory and I'm just a newbie. So annoying. I have to be home by 7."
She flipped gracefully onto an abandoned iron ship and walked into the large room.
"What's this?" She paused, noticing a 1x1x1 wooden box placed oddly in the corner.
She inspected it curiously, circling it, tapping its surface. Tak, tak.
Suddenly, she heard a rhythmic tak-tak-crack sound. Her head whipped toward the noise.
"Someone's here," she whispered, immediately scaling the wall and crawling toward the source of the sound.
Manav, oblivious to her presence, was mining iron with his pickaxe. He was lost in his daydreams of building a flying fortress and a massive mecha. His companion panel had reassured him, "You can make anything; everything in this world is minable and craftable."
Ghost Spider stopped and watched from the shadows, her eyes widening as she saw a chunk of iron vanish and reappear as a floating block. Then, she noticed his pickaxe break and disappear.
"Oh, so that's how it works…" she muttered.
Manav sighed, looking at his watch. "Guess I'm done for today. No more pickaxes. I'll have to craft more and come back tomorrow."
As he turned to leave, his heart skipped a beat. Ghost Spider stood in his path.
"Hello, Gwen—no, Ghost Spider. Good evening! Hero work going well? Uh, bye! Gotta run!" Manav blurted out, trying to sidestep her.
"So, you've known all along?"
"What? No! I don't know anything! Just a nerd minding my business…" he muttered, quickly mining his crafting table.
Swish!
"Hey, what are you doing? I'll be late if I don't leave now! Remove this silk!" His hand was stuck to the crafting table, webbed by Ghost Spider.
"Don't pretend," she said, removing her mask.
Manav froze. "Oh, hey, Gwen. Wow, you're Ghost Spider? What a shock! Your dad would be so proud if he knew his daughter was saving lives."
"Cut it. What are you doing here? What's with all the disappearing iron, the weird tools, and the blocks? Do you have powers? If you do, why aren't you helping people?" Gwen asked.
"Look, I needed iron for self-defense. It's just rusting away here, so why not? As for powers, I'm not some saint like you, Spider-Man, or the Avengers. My abilities are for construction, not fighting bad guys with knives and guns."
He hastily crafted shears from the iron and cut the web binding his hand. Surprised, he saw an achievement notification pop up.
"Also, Gwen, if you try to stop me, I'll tell your dad his 'precious daughter' risks her life every day as a superhero." He smirked and walked away.
Gwen clenched her fists, her eyes welling with tears.

Manav exited the dockyard through a dog hole, heading to where he had locked his new bicycle.
But all that remained was a broken lock.
"Damn it! I hate this crime-ridden city—especially this Marvel version of it!" he cursed, storming toward the bustling docks.
"Taxi!"
A cab stopped, and he got in. "Queens, please."
The taxi barely moved when Boom! A humanoid figure crashed onto the hood.
Manav cursed under his breath, spotting a purple figure approaching from the left, grinning maliciously.
Manav scrambled out of the taxi and placed his crafting table on the road. His hands worked quickly, crafting a bow and arrows.
The purple figure shouted, "Jessica, you can't escape me! We're meant to be! I'll make you my perfect bride!"
Jessica Jones, pinned to the hood of the taxi, couldn't move, her body controlled by his powers. Tears streamed down her face as she struggled in vain.
Manav muttered to himself, "Focus. One shot. I can do this."
He nocked an arrow, aimed carefully, and jumped to his right to align his shot. The crosshair in his vision locked onto the purple figure's throat.
Swish!
The arrow flew, piercing the figure's neck. He froze, gurgled, and collapsed, blood pooling around him.
Jessica felt control return to her body. Shaking, she stepped off the taxi.
Manav removed the crafting table and walked past her. "He's dead. You're free. None of this was your fault."
Jessica stared at him, speechless, before quietly walking away.

Minutes later, black SUVs arrived at the scene. Men in suits inspected the area.
One agent examined the arrow embedded in the wall. "Interesting," he murmured.

As Manav walked away, he muttered, "Why didn't she thank me? In all those fanfics, the damsel always falls for the hero."
He slowed his pace, hoping she'd call out to him. When she didn't, he glanced back and saw she had already disappeared.
"That's it! I'm never trusting fanfics again!" he shouted.
Jessica, walking down the street, heard his outburst with her enhanced hearing. A small smile graced her lips.
