徐青云控著機甲， chunks of earth shattered beneath its massive tread as each step it took left behind an indentation as deep as a crater. The roar of each impact was thunderous, echoing throughout the quiet area, and those who had ventured outside their facilities to witness this spectacle were left in awe.

"Is this real?" someone whispered, their voice barely emitting above the din of the mechanical beast.

The ground beneath their feet trembled with each powerful move, making it hard to believe that this was not a dream. Across the base, word had spread quickly. The sound of thudding boots and the realization of the ground's tremors had mobilized the staff.

"Is something happening?" someone asked, their voice echoing with concern.

"Did you hear that? It sounds like someone is hammering on the ground!" another replied, stepping out of the building cautiously.

"Let's go check it out!" a third person exclaimed, and they were off, a bustling group of men and women who had been thrown into a state of confusion and curiosity.

As they reached the edge of the base, they were met with an oversized figure, a childlike exuberance visible in its every action. The massive silhouette of the mecha, decked out with a towering cannon reminiscent of the tank it was based on, was a sight that defied reality.

"What on Earth is that?" a military personnel exclaimed, rubbing their eyes in disbelief.

"It looks like a mecha..." someone pointed out, though it was obvious to all.

"This isn't possible," someone else muttered, their voice filled with disbelief. "Our military has no such thing!"

"No applications for mecha tests here or anything," a third person confirmed, confusion etched on their face.

"Then what is this?" someone demanded, their voice tinged with urgency.

That was when the office of General Shen Yining was thrown into a chaos of its own.

Shen Yining, perched in his leather chair, was deeply engrossed in a complex set of blueprints, his brow furrowed in concentration. The圖紙 before him were intricate, but the meaning behind them was a mystery he couldn't unravel.

"How can this little Lu draw something like this?" Shen muttered to himself, scratching his head in frustration. He had been poring over these since the completion of the super-energy particle collider modification, but to no avail.

"This is as clear as a book written in a language I don't understand," he said, finally throwing up his hands in defeat. "I need to find the time to confer with Lu."

With that, he gathered the blueprints and was about to leave. But as he made his exit, a series of mighty booms shook the entire base, followed by the sharp tremors felt on the ground.

"What's happening?" Shen asked, shocked, steadying himself against the desk.

An earthquake? But earthquakes don't make such sounds...

No, it wasn't an earthquake. It was something else...

He glanced outside, but all he saw was the colossal figure, still running and leaping around the base, its actions as erratic as a child's excitement.

"What is that?" Shen gasped, his eyes wide with shock.

He reached for the phone on his desk just as a shrill alarm interrupted his thought process.

"What's going on?" Shen demanded, picking up the phone, his voice echoing with urgency.

Before he could speak, a voice on the other end was fraught with panic.

"Mr. Wang, something is wrong!" the voice exclaimed. "We've found a massive mecha in the base; it's launching terror attacks on us!"

Wang was taken aback, the notion of a mecha terrorizing the base absurd. He knew about the mecha; it was one he had seen transform right before his very eyes.

But terror attacks? He looked up, staring at the leaping figure of the mecha, which was now more childlike than terrifying.

This was no terror attack; it was a test!

"Discharge the alarm, this is just a test!" Wang declared, hanging up the phone, then explaining to the surrounding crowd.

General Wan Zhizhi, who had joined the group, took it all in stride. He was amused and curious about the mecha, watching intently as its pilot, Xu Zhengqing, moved it with both precision and power.

"The test can end now," Lu Feng announced, reviewing the data he had collected.

Xu Zhengqing stopped his actions, his excitement bubbling over. "I'm already familiar with the mechanics of this mecha. Teacher Lu, are we moving on to the firing test?"

"Stop!" Lu's voice was firm, while Wang Lianan cut in, his expression a mix of surprise and a sense of duty.

The group looked at Wang, who quickly explained that the target range they had used for the tank test was still unrepaired, and the remaining ranges couldn't handle the impact of the mecha's cannons.

"Then we should find an uninhabited mountain area for the test," Wang suggested, receiving nods of agreement from everyone present.

"Alright, let's find a mountain area to test it out," General Wan agreed, leading the group towards the numerous mountains surrounding their base.

But just as they were about to set off, Wang Lianan's phone rang again.

"It's a call from our superiors," he said, looking at his phone and his expression growing increasingly solemn.

"What happened?" the group asked curiously.

Wang sighed heavily, his face filled with gravity.

"The weather has been hot and dry recently. There's been a blaze in the mountainous area, and the fire is spreading. The fire departments will take a long time to arrive, and I need to rush soldiers to control the flames."
