My supermarket is connected to all worlds, and I've won so much money handing it over to the st

The group immediately drove to the scene.

At the same time, as the mecha accelerated, Gu Xixi felt her ears and body gradually becoming uncomfortable. At first, she could barely bear it, but she couldn't handle it when the speed exceeded 500 kilometers per hour.

[Flight speed detected exceeding pilot's tolerance limit. Pilot mode changed, cabin gravity altered...]

After the mecha finished broadcasting its message, another nearly transparent shell appeared around Gu Xixi, as if an egg was enveloping her. Then, a disgusting black substance, similar to "venom," began to flow into the egg, sealing her away.

But after being sealed, Gu Xixi felt even more that she had truly achieved the effect of human-machine integration, with a higher degree of integration and a clearer vision... Amazing.

The feeling of being pulled by gravity was gradually disappearing, and I felt very relaxed.

When she turned around, the virtual figure was still beside her.

So reassuring.

Gu Xixi pressed the accelerator to the maximum speed, flying at Mach 5 (the speed of a supersonic fighter jet) for several laps before stopping. Under Elder Su's command, she then launched an attack on a distant target, creating several large craters to collect data before finally emerging from the mecha.

But she felt that half of her mental energy had been lost.

I'm so tired!

"Mecha warriors require a high level of mental strength. If you hadn't practiced military boxing for so long, you wouldn't have been able to last this long," the system explained in her mind.

No wonder, Gu Xixi sighed: "Does that mean I can't test any large mechs?"

[Yes, but you'll be exhausted for several days, affecting your daily trading, so I suggest you don't.] After the system finished answering, Gu Xixi decided to give up.

Let her do it when she's capable; right now, her multiverse trading business is the most important thing.

The mecha transformed back into a pendant, and Gu Xixi held it in her hand. Sure enough, her limbs were already half-weak, as if she had just run three thousand meters. Chu Feng, with his excellent observation skills, quickly caught her.

Old Su was still grinning when he hurriedly asked, "What's wrong, young friend Gu? Are you afraid of heights?"

"No, Elder Su, controlling medium and large mechs in combat requires higher mental strength, which I lack, so it's a bit difficult for me. For the larger mechs later on, we need to find someone with excellent physical fitness to test them."

After Gu Xixi finished explaining, Old Su seemed to have thought of something, and nodded as he wrote it down.

"That's right. The special substance that connects to your brain and envelops you is probably a special medium that allows your neural activity and conscious commands to be connected to the mecha, achieving the effect of your brain becoming the mecha's brain. That's why the human-machine integration effect is so good..."

Consequently, the mental and physical demands on the operators are indeed very high.

After all, pilots are selected from among thousands of candidates these days, let alone mechs that surpass modern technology.

He hadn't thought things through... But right now, of everyone present, only Chu Feng and the other special forces soldiers met the physical requirements, but they were all there to protect Gu Xixi...

Old Su looked around, feeling troubled, when a hearty voice rang out, "Let me test you. My physical fitness is the best within a hundred kilometers."

Several military vehicles were parked not far behind them, and a group of men wearing colonel and general badges walked over. The man in the lead was wearing ordinary training clothes, so his rank was not discernible.

But when they approached, Chu Feng and the others saluted him, and Gu Xixi knew that his rank was not low. She then politely said, "Hello, leader."

"Hello, I'm the person in charge of this military region, my name is Mao De. I find yours quite interesting, that flying around earlier was pretty good. Let me test it for you. Don't say too much, I can still make the decisions in this area."

Mao De nodded to Gu Xixi and made the request directly. Gu Xixi saw that Chu Feng also nodded, so she agreed.

Seeing that everyone agreed, and knowing his experiment needed to continue, Old Su pulled Mao De aside to explain the instruction manual. "This manual shows that this large mech is 18 meters tall in standby mode and 60 meters tall in combat mode. Its overall weight can reach over 6000 tons, and it can carry two people at the same time. Its arm strength is..."

Mao was shocked. 60 meters tall? That's almost like a giant mecha from a movie. A real-life version... is that even possible?

"Its cockpit is in its brain, and its chest holds blue-light guided bombs with high precision guidance and penetration capabilities, capable of penetrating up to 50 meters of soil or 10 meters of concrete to detonate... There are ten in total. Its fists can generate 800,000-volt electric arc pulses, and it also possesses ten small nuclear weapons, including hydrogen bombs... Even if it stands still, its body armor is incredibly tough, almost indestructible, and can serve as a massive shelter..."

Compared to the other mechs, this largest mech is purely for combat and possesses immense destructive power—a devastating weapon that kills either the user or the enemy.

It is far more powerful than any other weapon of the same function known internationally.

After the introduction, Mr. Su asked again, "Are you really sure you want to take the test? This could be dangerous for you as well."

If I just stay inside the mech, won't my protection mechanism also extend to other pilots? That way, I shouldn't need to expend any mental energy, right?

Gu Xixi checked with the system again to confirm. If so, this was the safest testing method at present.

Gu Xixi seemed to hear a soft sigh, followed by the system's firm reply: "Yes."

After she told everyone, Mao De insisted on testing it as well. The two of them took the mecha pendant together. When the others saw this, they quickly ran away until they saw Gu Xixi turn into a small black dot before waving to indicate that it was okay.

Gu Xixi skillfully pressed the switch, and the scene before them changed rapidly. They were in the midst of it, so the shock wasn't too great, but for others, the gaze went from eye level to looking up, and then to looking up at the sky until their necks ached from the upward curve before it finally stopped...

In the distance, a colossal monster, 20 stories tall, rose from the desert. Its muscular body gleamed in the sunlight. It brandished its fists, and its massive mecha eyes stared down, radiating immense pressure.

"Chu Feng, quickly help me up! I have megalophobia, it's terrifying!" Chen Yu's legs were a little weak; this was truly a gigantic creature.

Old Su was incredibly excited, holding the walkie-talkie and excitedly directing, "Gu Xixi, please begin the test."

Gu Xixi was responsible for sitting in the co-pilot's seat in the cabin, while Mao De sat in the pilot's seat. The two could hear the sounds in sync, so they started using each function one by one according to the instruction manual.

Maod completed some routine functions quickly, but when it came to lethal combat weapons, he had to drive the mech a little further away before finishing them to avoid accidental damage.

Suddenly, three small red dots appeared on the mech's intelligent virtual screen, and the mech's voice alert began to report: [Warning, three fighter jets with stealth capabilities have appeared and are approaching. Should we issue a warning or shoot them down?]

Gu Xixi was afraid it might be one of their own and was about to ask when she heard Mao De take out his communicator and ask the military, "Within ten kilometers of the camp, coordinates... have any fighter jets been spotted? Three. Have we dispatched any... no, okay."

After speaking with the other side, Mao Dexuan issued a warning before explaining to Gu Xixi.

"We don't have any fighter jets on missions, and our own monitoring towers haven't detected them. It's probably a new type of stealth material invented by another country, and they're deliberately coming to test it. Judging from how familiar they are with this place, it's probably not their first time here."

The mech warning ended, and the opposing fighter jets were also dumbfounded. After taking a closer look at the behemoth standing in the desert, one of them exclaimed, "We were actually discovered this time, and we even received a warning, but it wasn't from their control tower. Look, what's that? A mech!"
