Seeing Rowan's sincere eagerness to learn, Director Norris nodded in approval.

"Since we're on the topic," he said, "I'll take this opportunity to teach all of you together."

He glanced at Luo Feng and the other senior trainees. It wouldn't look right to single Rowan out in front of everyone, so he turned it into a group lesson.

The senior trainees were thrilled.

After all, Director Norris was the head of the dojo and only gave lectures once a month usually to classes of over a hundred. A small, focused session like this was a rare privilege.

Director Norris began with the fundamentals of force generation, explaining each stage of the process in clear, accessible terms. Then, he offered targeted feedback tailored to each trainee's weaknesses.

Rowan, in particular, received the most detailed guidance.

By the end of the nearly two-hour session, Rowan felt as though a fog had been lifted. His understanding of combat mechanics had sharpened significantly.

Director Norris's insight far exceeded that of Instructor Wu. With just a few corrections and drills, Rowan's punching power jumped from 786 kg to 803 kg.

He could feel it once he fully internalized the techniques and improved his body a little further, he'd reach the threshold of the pre-warrior level.

Before leaving, Director Norris quietly pulled Rowan aside.

"From now on," he said, "you may come to me once a week for one-on-one instruction."

After giving those instructions, Norris left, with Instructor Wu trailing respectfully behind.

Rowan and the others continued training for another half hour.

During that time, the senior trainees warmed up to Rowan, engaging him in casual conversation.

Luo Feng, especially, made a point to connect. When Rowan respectfully addressed him as "Senior Luo," he just smiled and waved it off.

"Just call me Luo Feng. No need to be so formal."

"Heading out, Rowan?" he asked as they finished up.

"Yeah," Rowan replied with a nod.

They walked to the locker room, cleaned up, and exited the dojo together.

"See you next week, Luo Feng," Rowan said at the door with a wave.

Since Director Norris had offered private lessons, there was no need to visit daily. Once a week would be enough.

Luo Feng, however, was approaching summer break. He would probably be training here every day.

"Sounds good. Take care!" Luo Feng replied, waving as they parted.

Rowan walked to the parking lot, unlocked his electric car, and slid into the driver's seat.

Luo Feng stood frozen as he watched the sleek, high-end vehicle worth over 800,000 yuan glide away.

He hadn't expected Rowan to be so wealthy.

Driving a luxury car like that at sixteen suggested his family's assets were in the tens of millions.

Even Zhang Haobai, who loved showing off, only drove something in the 200,000 range.

Rowan's background was clearly on another level.

Still, Luo Feng didn't feel discouraged. He had grown up in hardship and built a resilient mindset. Rowan's success only deepened his resolve.

Meanwhile, Rowan glanced at his phone. Several missed calls from Howard Zhou blinked on the screen.

He tapped to call back.

"Hey, Howard! How did it go with the shipment?"

"Perfectly!" Howard's voice was bubbling with excitement. "I even got someone from Hongning Base City to inspect the goods. They were very satisfied."

"Oh? What'd they say about the Kroluminum?"

"They want to transfer it directly to you from the headquarters of the Limit Martial Arts Dojo in Jiangnan Base City. All they need is a list of goods equal in value."

So they really were internal procurement staff from the dojo, Rowan thought.

"Alright, then. Let's stick to our original price 7 yuan per kilogram. One hundred thousand tons, that's 1.4 billion credits. I want 1 billion of that converted into Kroluminum. I'll send you a list to match the value. The remaining 400 million, transfer it to my personal account."

Rowan made a quick mental calculation as he spoke.

He needed the 400 million in cash to buy more cultivation resources. The beast meat and medicinal bath packs he had stocked earlier were nearly depleted.

"Understood!" Howard replied, practically giddy. "With this deal alone, I'm officially a billionaire."

"Oh, and by the way," Howard added, "the buyer said they're looking for a long-term supplier. They want one hundred thousand tons of rice every week. What do you think?"

Rowan's eyes sparkled.

Weekly orders of that volume? That was enormous.

And given the buyer's direct ties to the Limit Martial Arts Dojo, future expansion was practically guaranteed.

"Absolutely. You don't need to worry about the supply end I've got it covered."

"Excellent! I'll get back to them right away."

Rowan hung up, feeling elated.

He hadn't expected the rice business to scale this quickly. Not only were his sales soaring, but he'd also secured a reliable channel for acquiring Kroluminum.

A perfect win-win.

When he returned to his apartment, Rowan sat down and drafted a procurement list for the Kroluminum. Once finished, he sent it off to Howard Zhou.

But instead of immediately returning to the Marvel world, he opened his computer and began researching electric vehicle technology.

The results stunned him.

In the Swallowed Star world, new energy technology had already advanced to an astonishing level. Solid-state batteries were fully mature.

Nearly 90% of all power was now electric. Fossil fuels had been completely phased out.

It made sense. After the Great Nirvana, most of Earth's oil fields had fallen into monster territory. Humanity had no choice but to embrace electricity.

With global coordination and unified effort, energy development had leaped forward.

Rowan recalled that in the original novel, even advanced weapons like laser cannons used modular batteries as power sources.

"Modular batteries…" he murmured, reading the results while stroking his chin.

In the Marvel world, this would trigger an energy revolution.

Of course, he wasn't planning to bring over top-tier battery tech just yet he wasn't powerful enough to acquire those systems anyway.

But the Swallowed Star world had long since moved past earlier generations of solid-state batteries. The older models were now obsolete freely available on public networks.

What counted as junk here would be a goldmine back on Earth.

His eyes gleamed as he sifted through dozens of technical documents.

These solid-state batteries were vastly more advanced than anything Tesla had ever produced.

Transplanting even one of these systems into the Marvel world would be enough to start an energy empire.

Without hesitation, Rowan selected three specific designs and saved them onto a USB drive:

Prismatic Lithium Iron Phosphate Series

Prismatic Ternary Series

Large Cylindrical Ternary Series

Each package included full documentation blueprints, manufacturing principles, and implementation guides.

They would be incredibly easy to replicate.

To further shorten development time, Rowan also downloaded data on fast-charging systems and next-generation electric drive technology.

Obsolete in this world, yes but revolutionary in the Marvel universe.

Once everything was backed up, Rowan shut down the computer, removed the USB drive, and with a subtle snap of his fingers

He vanished, returning to the Marvel world.
