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

He took her pulse calmly, and simply asked, "How has your appetite and drink been lately, Auntie?"

"I eat and drink normally, and have a good appetite, but I always feel very tired and can't wake up," Gu's mother answered truthfully. Compared to Gu's father, her symptoms were indeed much milder.

"I used to have heart palpitations about two to three times a week, but now they're almost nonexistent, and even when they do happen, they pass quickly. Has it gotten worse?"

After asking her question with concern, Gu's mother realized that her question was inappropriate.

Shen Qingyan hadn't taken her pulse before, so how would he know if she was getting better or worse?

Shen Qingyan simply nodded, "I don't have much medical skill, but I can record your pulse and take the place of a good doctor in observing, listening, questioning and feeling your pulse. You don't need to worry, being able to eat and drink is a good sign."

Even if she is very sick, as long as she can eat and drink, it means there is still hope, and she still has time to wait.

However, Gu's mother's condition is far more serious than Gu's uncle's, and is likely more dangerous. What if something happens to him before Gu's mother recovers...?

He needs to hurry.

His words put Gu's mother at ease.

He observed and questioned Gu's mother in more detail, then memorized the information. With only two minutes left, the fog began to ripple. Shen Qingyan stood up. "Miss Gu need not worry. However, we will not see each other again for three days. Please exchange half of the grain for compressed biscuits. Also, I need more seeds. Thank you for your trouble."

Gu Xixi had a vague feeling that something was wrong. She felt that every word Shen Qingyan was saying was like saying goodbye, entrusting his son to someone, or making final preparations. But looking at Shen Qingyan's expression, she felt that she was overthinking it.

"Are you alright?" Gu Xixi couldn't help but ask.

Shen Qingyan paused slightly as she turned to leave, then smiled brightly, "It's alright, take care, Miss."

After saying that, he strode into the mist at a faster pace than usual, his figure looking resolute and determined.

[System, is the disaster relief in the parallel world not going smoothly?] This was the only possibility that Gu Xixi could think of that was causing Shen Qingyan's distress.

[According to the system check, everything went smoothly.]

Every person, even every world, has their own path and trajectory to follow, and countless experiences to go through. Problems may not necessarily arise from disaster relief, but all of this is irrelevant to you. You are merely a merchant across countless worlds. Your main mission, traversing three thousand worlds, is trading. Please remember this.

The system's reminder was delivered in a gentle tone, making Gu Xixi feel as if an old friend was nagging in her ear.

Yes, maybe she really is overthinking it.

Shen Qingyan will definitely ask if she needs anything.

At 6:40, a bluish-green mist rose, the gate to the primitive world trade opened, and the savage "Tree" arrived carrying a bundle of tree trunks on his back. As soon as he appeared, the fragrance of fresh leaves wafted onto Gu Xixi's face.

Gu Xixi's lips curled up slightly.

Ah, it's the taste of treasures, the taste of money, the taste of happiness!

"Wow, so much huanghuali wood! Gu Xixi, sell me two pieces later, I want to have a set of furniture made too." Professor Wei appeared behind her at some point and suddenly spoke up.

Gu Xixi was startled, but instinctively maintained the dignity and solemnity befitting a "god".

She gave a soft "hmm" and then looked at the tree.

He carried the trees for fifty minutes straight, carrying hundreds of rosewood logs, piling them up like a mountain in the yard. Finally, he carried back several hundred wild ginseng roots and put them down before he could rest and catch his breath.

The tree looked at the supplies God had given it, immediately bowed in gratitude, and then hurriedly carried them into the mist, afraid that it would be too late to return.

Gu Xixi noticed how he was working so hard and in such a hurry today, so she spoke up, "Shu, turn around."

The tree obediently turned its head, but its expression was anxious. "God Xi, is there anything you need me to do?"

"To reward your obedience, God is willing to increase the time available for travel to God's world. Starting today, you can stay here for twice the amount of time you used to spend each day. Do you understand?"

"You can bring more things to exchange, and you can ask questions about farming, building houses, etc. if you don't understand anything."

Upon hearing this, the tree immediately began to observe the bluish-green smoke. It was true... the smoke was still there. God really liked their Red Sand Tribe.

"Thank you, God Xi. Tree has something to tell you. The neighboring Yellow Earth tribe has merged with us and become one of our tribes. They brought a lot of animal hides and want to trade with you. Are you willing to accept them and trade with them?"

Wow, it's gotten even bigger.

Gu Xixi sighed, "If things continue like this, won't they quickly go from small tribes to large tribes, and then from primitive society to slave society? She's actually accelerating their social system development."

"can."

She replied, and the tree grinned, immediately running into the mist, returning shortly with a mountain of animal hides on its back.

The primitive people made animal hides in a simple way, so the smell of a pile of animal hides was enough to make Gu Xixi collapse. Fortunately, even though she held her breath, the staff quickly took her away in a cart, which allowed her to maintain her dignified "god-like" demeanor.

"One piece of animal hide, three pots, three packets of salt, or three packets of seeds?"

Gu Xixi pointed to the large amount of supplies remaining and asked, "Compared to rosewood, this price is quite reasonable."

Shu pointed to the supplies with great interest, "Can I exchange a little of everything?"

“Okay.” Gu Xixi nodded, and the staff immediately began exchanging the items with him, counting out the amount, and letting him take it back.

After the exchange, Tree began asking about the detailed steps and problems that occurred during the process of making pottery jars and cultivating and germinating seeds.

Professor Wei studied biology and also knew a little about farming. In addition, he came from a farming background, so he was very good at it and could handle the primitive man tree with ease.

The trees ran back and forth while studying, recording what Professor Wei said in their own way.

He didn't leave until the two hours were up, reluctantly.

As soon as he left, the bluish-green smoke gradually turned into silvery-white smoke. When the silvery-white smoke completely replaced the previous color of smoke, the system prompted again:

[The original world has completed six trades and is now opening its third trading world. The trading partner has been selected and will arrive soon. This world is a technological world, originating from Earth in a parallel star system, and is three hundred years ahead of the host's Earth.]

Listening to it again, Gu Xixi was still nervous. In this amazing world, she was protected by the system and not afraid of danger, but what about the others?

What if the people who come bring lethal weapons? We're not going to play any more games.

Everyone there is an elite talent; the loss of even one of them would be heartbreaking.

[Background information on the technological world is as follows: Technological advancements are 300 years ahead of the rest of the world; controlled nuclear fusion, lithography technology, digital society, aircraft engine nacelles, and dark matter technology have all been solved.]
