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

Gu Xixi kept nodding, while her mother kept saying thank you.

Speaking of three days... Gu Xixi thought of all the trading worlds. She couldn't even keep track of the three-day intervals between different worlds, and it was too rigid and troublesome.

[System, could you please change the rule that the world portal can only be opened every three days after eight attempts? Since it's a six-month period anyway, and it's once every three days, that's 60 attempts. Can you just limit the number of attempts directly?]

This makes trading between different worlds much more convenient.

[The Multiverse Trading System is modifying your rules. Once the rules have been successfully modified, you will now have the opportunity to trade 60 times within six months after completing eight transactions in each world. However, you can only have one transmigration opportunity per day.]

Gu Xixi: [Brother Tongzi, I really love you so much.]

It's astonishing that such a reasonable, understanding, and swift system exists in the world.

The system remained silent, so Gu Xixi quickly informed Shen Qingyan of the new rules. Shen Qingyan was overjoyed; this would indeed make disaster relief much more convenient.

He gazed deeply at Gu Xixi, his eyes filled with intense emotion, unable to look away.

Gu Xixi realized this time and immediately didn't know how to respond. She unconsciously held her breath, extremely nervous.

That glance only lasted a few seconds. Shen Qingyan had already left, but she hadn't recovered yet. The feeling of being enveloped by that burning gaze and unable to breathe was just too intense.

Chen Yu walked over, his lips curving into a smile. "So, now you can see it, right? Are you tempted? A pure-hearted guy like Shen Qingyan is definitely right for you. Not to mention you, I like him too."

Chu Feng: ?

He silently moved away from Chen Yu, and Gu Xixi also exclaimed "Ah!" before retreating silently with a questioning look on her face.

Chen Yu was speechless. "I'm not your sister. I'm just expressing my appreciation. It's normal for men to appreciate other women."

"Admire you my foot! Get back to work, Xixi. If he's slacking off, just give him a good slap. Don't be afraid." Old Chen came up behind Chen Yu and gave him a good scolding.

Let him talk nonsense, just go to work.

Gu Xixi was startled by Old Chen's bravery and simply nodded to appease him. The mist outside the door was changing, and the tree was about to appear.

The staff immediately transported all the things Shen Qingyan brought to the next building, and Gu's mother's medicine was also sent for testing. When Chu Feng walked back to Gu Xixi's side again, the tree also appeared.

In addition to bringing the agreed-upon different varieties of plants and stones, he also brought several tall Ganoderma lucidum mushrooms, which looked like huge red umbrellas and were quite spectacular.

Professor Wei, a biologist, arrived immediately upon hearing the news and carefully carried the tree away. This time, he taught the tree some patrol arrangements, sentry post settings, and training methods for its people.

The tribe is now famous for receiving divine help, and small tribes request to join or pledge allegiance every day. The tribe's expansion has made other large tribes wary, so the tribe's protection has become a problem.

Therefore, he reluctantly left only after Shu proposed exchanging weapons.

After he left, Gu Xixi looked at the mist with even more fervor. Emerald should be coming today, right?

“We’ll most likely choose melee weapons for the trees: steel blades for close combat, spears for hunting, and animal traps for assistance. Any more than that, and the damage to the ecosystem would be too severe,” Chu Feng discussed with Gu Xixi.

After all, primitive people had great physical strength and no concept of sustainable development.

“I think it’s okay, that’s really the best we can do. Let’s arrange it like this. Jade is here, let’s get on with this first!” Gu Xixi nodded and immediately ran over. She carefully examined Jade’s neck; her skin was as white as snow, without a single scratch.

"Did you recover so quickly? Or is it that a month there is only one day here?" Gu Xixi asked curiously.

Jade reverted to her cold demeanor. "It's just a special medicine. Let's make this clear first: this medicine is a secret and cannot be exchanged. Here, is the water storage ball you wanted."

Gu Xixi was about to ask about the special medicine when she was stopped. Fine, if you don't want to sell it, then don't sell it.

Emerald handed over several enlarged suitcases, which Gu Xixi took. The other staff members immediately took them and began to check and count the number of suitcases. Meanwhile, Emerald started running back and forth between the two worlds, bringing back a long line of suitcases at once.

She pulled the strung boxes toward this side like she was pulling a rope, handing them to Gu Xixi one by one.

"I'll give you a total of 5000 water storage balls. The last two large boxes contain 96 water storage balls, which is just enough to hold all the water we agreed to trade. Just give them to me in batches. Let me know if you need anything else to exchange along the way."

"By the way, this small box contains all the data on the production of various types of mechs."

Gu Xixi stepped aside, and Chu Feng handed her a red-headed document containing the items they had already inquired about. Gu Xixi stated directly, "We no longer need mechs for the time being. We need to exchange new technologies. For example, a space station with a capacity exceeding five figures, or a spaceship. Have you developed to that stage yet?"

If she's not mistaken, the National South Gate project, which many netizens have speculated about, has been underway for a long time.

Exploring the universe is a dream for many and a pursuit for many scientists. Emerald smiled slightly, noting that these two technologies were cutting-edge in their time.

How could I possibly reveal it so easily?

"I can provide the information, but you can only choose one: a space city that can accommodate 10 people or a spaceship. In exchange, I want all the remaining water. Once you've made your choice, our deal will be considered settled for now."

Jade was very confident that Gu Xixi couldn't possibly refuse her two research achievements being sold so cheaply.

If freshwater resources weren't truly precious to them, and if the two worlds weren't unable to plunder each other and if safety weren't guaranteed, she definitely wouldn't have agreed.

Gu Xixi pondered for a moment, then exchanged a glance with Chu Feng.

According to the document, it would be best to acquire both technologies. If that is not possible, the space station should be the priority. No, a space station that can accommodate 10 people should indeed be called a space city.

But she wanted to take both, to make China completely surpass the rest of the world, to be ahead of other countries for hundreds of years, and to make them tremble.

The technological world, lacking freshwater resources, is willing to exchange so much advanced technology for them, all in order to gain opportunities and time for survival. Besides water, anything else can sustain life.

The system's subtle hint was immediately understood by Gu Xixi. A brilliant idea flashed through her mind, and she quickly replied, "I choose all the information about Sky City, including all the necessary materials, energy, power systems, and so on. To express my gratitude, how about I treat you to a meal when you come again tomorrow?!"

When Gu Xixi suddenly made a request unrelated to the transaction, Jade was taken aback. Was there some kind of conspiracy?
