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

"So, what should we exchange with each other?" Gu Xixi muttered to herself. Others are hundreds of years ahead in technology, what could they possibly lack?

She always had this feeling that she was poor, but she was doing business with billionaires.

However, upon closer reflection, every era has its own advantages and disadvantages, and their world must also contain things that the future world needs.

She should be more confident and not underestimate herself before even discussing business, which would undermine her self-assurance.

The silvery-white smoke began to change, gradually extending to a height of at least three stories. As everyone looked up, a colossal object gradually approached, shrouded in the smoke.

Because Gu Xixi had a systematic defense and protection mechanism, everyone felt at ease, so they took her directly to the roof of the supermarket, where they barely made eye contact with the enormous creature that had just emerged from the smoke.

Only then did everyone see clearly the true appearance of this behemoth... majestic, tall, and awe-inspiring.

Chu Feng, who was usually calm and composed, opened his mouth slightly in surprise this time, uttering a shocked expression of disbelief, "This, this is a mecha!?"

He wasn't sure.

Gu Xixi wasn't sure either, because she wasn't usually interested in robots, and she had only heard about mechs from other people, which seemed to be some kind of super-sized robot that could be used for combat.

The enormous mecha was about 9 to 10 meters tall, and it was quite a sight under the bright blue sky.

His armor was entirely black in outline and plates, interspersed with golden radiance like that of a volcanic eruption. At the center of the radiance, there was a flowing red light that was constantly being released, but it was not warm to the touch.

Like a superhero suddenly appearing in the world, he was tall and strong, shining brightly even in the normal daylight, and not to be underestimated.

Even if Gu Xixi didn't understand, she still had to admire her; she was both capable and beautiful.

The mecha slowly moved its body, looking left and right before looking down at Gu Xixi and her group.

Its large eyes seemed to have a human-like expression.

It was the people inside who were watching them.

"Gu Xixi, talk to her." Chu Feng was the first to come to his senses and gently patted Gu Xixi's shoulder. The next second, Gu Xixi felt that all the eyes of the person inside the mecha were on her.

"Hello, friend, this is Earth in 2024. Welcome to this place. I am Gu Xixi, a trader from countless worlds. It's a pleasure to meet you."

Gu Xixi's words were translated, and the mecha nodded. Suddenly, its huge hand raised an index finger and pointed to the ground, making a deep and resonant voice, like the voice of a mecha in a 3D surround sound movie theater.

A mechanical voice said, "Get down. I will shrink. Please tell me more details about this world."

Gu Xixi nodded, and the group immediately went downstairs. As soon as they entered the backyard, they found that the mecha was transforming. In a fantastical ten seconds, like a movie special effect, the ten-meter-tall mecha became more than three meters tall.

A head also emerged from within, a human-shaped head, a blonde girl with black eyes, who looked strong and powerful, and was estimated to be no more than twenty-five years old.

It turned out to be a girl.

Gu Xixi was surprised. The girl had a cold expression and icy eyes, and curiously looked around. "Earth three hundred years ago, interesting."

She even took a few deep breaths of fresh air before looking Gu Xixi in the eye.

"Gu Xixi? There's no such thing as a free lunch. Tell me what you want, and if I can afford it, I'll naturally negotiate with you."

Hmph, trying to test her bottom line? No way.

Gu Xixi smiled slightly and sent the question back to her, "Then tell me about your world first, what Earth will be like three hundred years from now, and what good things it will have, otherwise I won't know what I should exchange with you."

The girl's face remained cold, but her eyes had gained a sharper edge.

She raised her chin slightly, a hint of pride in her voice. "Of course, it's space exploration and gene technology. Three hundred years later, we've found the key to human lifespan through research on human telomeres. Through long-term experiments, gene replacement technology has matured, and ordinary humans can now live to 200-300 years old."

"Moreover, humans don't need to eat. Furthermore, we have already established a permanent research base on the moon, built a human town on Mars, and traveled to space via space elevators for the price of an airplane ticket. In short, our technological level is far beyond what we can imagine now."

Xu Yue let out a soft "wow," that's amazing! But living so long... She blurted out, "What will we eat in the future? And another soul-searching question: Did Mount Fuji erupt? When did it erupt? Are the people at the foot of Mount Fuji alright?"

This is the most important thing for her besides working and making money.

It's unclear which of her questions touched a nerve, but the mecha girl's face suddenly turned sour. "There is no Mount Fuji. It has never existed in history. Earth has gone through four eras, but only our Chinese race has remained strong."

She then chuckled softly, "It seems we're not from the same planet."

Xu Yue's expression immediately changed; she realized she had said something wrong.

She looked to Gu Xixi for help, but Gu Xixi was not in a hurry; she was very calm.

"We are indeed not one Earth; we are parallel worlds, similar yet different. We certainly have complementary aspects and mutual needs. Our Earth is a battleground of many powers, so your advanced technology is something we need. I think you also need our abundant resources, clean water, soil, and even plants..."

When they talked about what they needed, the girl's expression changed again, looking annoyed that her thoughts had been guessed.

The system also added to Gu Xixi's mind: "Their Earth's technology is highly advanced, so natural resources, especially non-renewable resources, are scarce. Water alone is enough to negotiate with them."

Gu Xixi became even more certain of her thoughts and continued to say to the mecha girl, "So you can't afford to eat not because you don't need it, but because there's no food for normal humans to eat, right?"

She guessed right!

The mecha girl carefully examined Gu Xixi. This so-called interdimensional trader was more powerful than she had imagined and should have enough resources to exchange with her.

But do they have enough resources?

"I am a trader from all realms. Even if the resources you need in this world are insufficient, I can go to other worlds—thousands of worlds—to find them for you and trade them. Now, have you made up your mind?"

The mecha girl then revealed a faint smile, "Hello Gu Xixi, my name is Emerald, and I am the mecha warrior commander of Ferrep Earth. I came here by accident while on a mission."

"The first thing I want to exchange with you is water, clean fresh water. By the way, you can travel through countless worlds, so can you come to our Earth?"

If possible, could she also bring an army to this Earth... and plunder it?
