Star Iron, building an empire starting with game development

"The Goliath Tripod Mech... you know, the one that almost beat three Martian mechs, with its big main cannon, thick armor, but super slow speed? Let's just produce a few of these." Xing looked at the blueprints in his hand and threw the thing into the factory.

"Then there's Sky City... Its power goes without saying. It comes with a large number of combat robots, making it a good choice to pair with Goliath-class flying warships. Oh, and those flying paramecia-like flying warships too."

"Then there are ornithopters... let's just put them on flying warships as carrier-based helicopters. As for gunboats and those three WWII planes, let's talk about them when we have a flying aircraft carrier," Xing said, glancing at the other items.

"Finally, there are those new warships... Forget it, just throw them all into the factory. We'll build them from the blueprints, and the ships will be disassembled and rebuilt." Xing threw everything into the factory in one go.

"I think you should build more flying warships and such. What if you end up in a world war someday?" the system said.

"Whatever, anyway, the factory produces at least a legion-level item," Xing replied with a shrug.

"Beep beep beep..." The communicator suddenly rang. Xing paused for a moment, then picked up the communicator, glanced at it, and answered the call.

“Sylvia? Why are you calling me all of a sudden?” Xing asked.

"We and our system have found a new person, we've found a new person!" Sylvia's tone was full of excitement.

"Do you need my help?" Xing asked Sylvia.

“Hahaha… Yeah, we do need your help. The newbie has agreed to join the group, but he’s at war with people in a world I don’t understand, and he needs some World War II-era weapons to help him out,” Sylvia replied.

“You timed it perfectly. I just received a batch of modern military equipment from within the planet. Tell me their coordinates, and I’ll send some weapons and equipment over in a bit,” Xing said.

"Thanks!" Sylvia's excited voice rang out, and then she hung up the call.

"The world coordinates have been received. What are your plans?" the system asked.

"Let's go to that world and see why they can only use weapons and equipment from World War II." Looking at the portal opened by the system, Xing responded and stepped inside...

Unknown World - The Frontline of a Battle

"Whoosh whoosh whoosh~ Boom boom boom——~~" Countless shells landed on the ground, and countless fiery flowers bloomed on the land that had been fought over dozens of times.

"Whoosh~ Boom~!..." A vehicle that looked like a tank with six legs was moving forward, with a large number of infantry behind and beside it.

"Boom boom boom..." In the distance, the enormous steel behemoth moved slowly.

"Buzzing..." In the sky, the two sides' flying warships bombarded each other incessantly.

"Aaaaaah!!!" The soldiers on both sides were caught in a meat grinder-like melee, and were occasionally bombarded by the cannon fire of those steel behemoths and the cannons of flying warships.

…………

In a grove of trees ten kilometers from the edge of the battlefield, a portal appeared, and Xing emerged from it.

Boom! A huge stray bullet streaked across the sky and exploded in the distance...

"Good heavens, what kind of weird weapons are these?" Xing glanced at the fierce battlefield in the distance and found the weapons and equipment there to be very strange.

"In the world of dieselpunk, there are classic, powerful, and brick-like weapon designs, but the weapons used by soldiers are no more than those from the early stages of World War II, and some parts of the world are even still in the era of World War I," the system said.

"Are those flying warships also?" Xing asked, looking at an airship in the distance.

"I know what you're trying to say. That thing is a bit high-tech compared to the Goliath-class flying warship. Although Sky City belongs to the steampunk era of the industrial age, it can't compare to the steel behemoths of this world," the system responded.

"Of course, those World War II-era fighter planes and bombers you have are still capable of fighting."

"Then let's use sheer force to send a large number of flying warships and... By the way, how efficient are the fighter jets in this world?" Xing asked, suddenly remembering something.

"A bunch of free-range chickens with two legs," the system said bluntly.

"Then send out all the BF-109s, F4Us, and B25s to cooperate with the flying warships to resolve the battle ahead." Xingyi waved his hand, and a large number of portals began to unfold...

…………

On the battlefield, the two sides fought fiercely, with their respective positions being contested hundreds of times within ten minutes.

"Whoosh! Boom—!!!" A steel behemoth was struck, and the violent explosion was something people had never seen before.

"Buzzing..." In the distance, hundreds of flying warships were heading this way, and beside those flying warships were a large number of fast flying units.

The battle commenced quickly, with a barrage of aerial bombs blasting the still-stunned troops on the ground to smithereens. Then, the flying warships unleashed their long-range naval guns, bombarding both the sky and the ground.

"Crack~ Crack~ Crack..." On the ground, a hundred Goliath tripod combat mechs walked from a distance. The weapons on the abdomen of the mechs directly fired lasers that swept across the soldiers on the ground who were stunned by the bombing, turning them into dust.

"That's strange. Didn't Sylvia say that the new transmigrator was in this world and even had a system? I've made such a big commotion, why hasn't he contacted me yet?" Xing Youqi said strangely on the bridge of a flying warship.

"Beep beep beep..." The communicator rang again, and Sylvia's holographic projection appeared in front of Xing.

“Star, have you found that friend?” Sylvia asked.

"Not yet, and the contact information you provided seems to be incorrect; the other party hasn't contacted me either," Xing replied, shaking her head.

"Hmm? Let me see..." Sylvia started operating the system, and then...

"Ah... I gave the wrong world coordinates."

“…Uh…” Xing opened her mouth as if to say something, but ultimately swallowed it back.

"Hehe~ This is the real coordinate." Sylvia smiled sheepishly, then transmitted another set of coordinates...

“…Fine.” Xing’s lips twitched, then she opened the summoning module and performed a summoning…
