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

Chen Yu's eardrums were almost ruptured from the sudden loud talking. He covered his ears with one hand while turning down the volume.

His father had been emotionally stable for decades, so this sudden outburst must mean that these things were extremely valuable and had special significance. So, he quickly rubbed his ears, grabbed his phone, and rushed outside.

Gu Xixi just left, so she should still be able to catch up.

However, when he ran out and looked around, he found that he couldn't even see Gu Xixi's back. He wondered, "Does she walk so fast?"

In the video, Mr. Chen, already wearing reading glasses, squinted as he followed the camera's movements, but as the search dragged on, he grew increasingly impatient, asking, "Haven't you found it yet?"

Chen Yu shook his head and gave an awkward smile, "Um, it seems like they've already left..."

"You useless piece of trash! You can't even do one thing right, and you still have the nerve to laugh!" Old Master Chen cursed, "You left them your contact information..."

"I'll keep her, Dad, stop scolding her. She'll come to my place tomorrow, there's still time!" Chen Yu then turned off his voice, creating a physical barrier.

He only turned on his voice again when the old man's expression softened in the video, but before he could speak, the other person only said, "Never mind, bring the things back first, and come back for a meal."

The video call was cut off the next second, as if watching him for even one more second would hurt my eyes.

Meanwhile, Gu Xixi was sitting in a black sedan by the roadside.

In the back seat of the car sat a man in his sixties, in excellent condition, wearing black-rimmed glasses.

He wore gloves and carefully examined Gu Xixi's hairpin.

A full ten minutes passed, and he still hadn't put it down, nor had he said anything else.

Gu Xixi didn't dare to speak. She had just come out of the shop intending to ask about prices at other shops when she bumped into the most senior professor in the history department of her former college.

The professor spotted her hair ornament at a glance and recognized her because she had audited many of her classes and answered questions when she was pursuing her crush. Her answers were so messy that they were remembered.

Normally, you wouldn't have the chance to meet such a big shot outside of school. The professor said he could help her take a look, so she naturally agreed. It was like someone offering a pillow just when you're about to fall asleep.

Moreover, the professor is renowned throughout the school for his noble character and would not harm her.

However, his expression doesn't seem too good.

【System, System Bro, what era is this from?】she asked in her mind.

The voice of the Multiverse Trading System appeared, its tone calm, like a news anchor: "[The Great Huang Dynasty in this parallel world runs parallel to Earth's timeline, and should, in practical terms, precede the Shang Dynasty on Earth.]"

Wow, that's really a long time ago, and the information matches what Boss Chen Yu said.

"Student Gu!" The old professor's voice startled Gu Xixi, who was engrossed in her conversation with the system. She immediately snapped back to reality. "Ah, what's wrong?"

“Gu, this hair ornament you have is very strange. It seems to be from before the Shang Dynasty, but many details don't match up. For example, the style, shape, and pattern shouldn't have appeared so early… I have a guess. If it's real, many historical records might need to be changed… This is a very important matter, so I can't make a judgment…”

The old professor carefully put the hairpin into the box, then held it in his palm and rubbed it repeatedly, reluctant to return it.

"How about this? You sell me this hair ornament for 20 yuan first, let me take it back and check it out. If its value exceeds that amount later, I'll make up the difference. Of course, I'll give you an invoice, and you can keep my ID card too, okay?"

This thing is too important; he really doesn't want to give it up.

The driver in front suddenly turned around. What kind of antique could make the professor lose his composure like that?

Gu Xixi was stunned when she heard that she was given an ID card. "There's no need to be so formal, Professor. Just sign an agreement and you can take your time to study it."

"Okay, great! Let's go, we'll draft an agreement right away. Here, let's add the teacher's contact information first. This is my green bubble, this is my phone number, and here's my ID card. This way you'll feel more at ease, and your parents will feel at ease too."

The old professor insisted on giving it to her, so Gu Xixi had no choice but to accept it. She drove to the nearest print shop and got the matter done. With the agreement in hand, Gu Xixi headed straight home.

Let's wait for the professor's results before discussing the rest.

She immediately took another taxi to a herbal medicine shop near her home after getting off the bus, intending to purchase a batch of Chinese medicinal herbs.

The old professor sat in the car laughing non-stop, then took out the hairpin, took a few pictures, and posted them to a group called "[A bunch of immortal old relics]":

【Look at this! I suspect it's an artifact from the Great Yu Dynasty. It looks a lot like some totems found in recently discovered tombs. Anyone interested in coming over to my house tonight to take a look?】

One sentence, three photos, and the whole group was in an uproar. Even the old man from the Chen family was in the group. For the first time in his life, he tagged him not to start a fight, but with the comment, "How come you're in here too?!"

Then a few pictures were shown, showing hairpins. At first glance, the two items looked like they came from the same family.

The old professor was also dumbfounded and replied, "Where did yours come from?"

The two then started discussing it in the group chat, and another Professor Xu quietly chimed in: "Hey, aren't you two sworn enemies? How come you're suddenly so harmonious?"

The next second, he saw that he had been kicked out of the group chat by the administrator: 【陈老老不死】.

Professor Xu: ...

Group members: ...

Half an hour later, Gu Xixi arrived at the medicinal herb wholesale market. The shop, which was over 200 square meters in size, was filled with densely packed medicinal herbs, and the air inside was filled with the fragrance of herbs.

Gu Xixi really liked the smell, so she took several deep breaths before queuing at the medicine counter. While waiting, she took out her phone to search for what diseases might occur during a prolonged drought and what medicinal herbs would be needed.

The search results showed that schistosomiasis and plague were the most likely causes, and there were also prescriptions from Kyoto Hospital.

So she scrambled the order, copied the names of the medicinal herbs and arranged them on a memo, making a list: green tangerine peel, poria cocos, artemisia capillaris, astragalus membranaceus, licorice root, sophora flavescens, gardenia, talc, scutellaria barbata, bupleurum chinense, phellodendron chinense, rehmannia glutinosa, buffalo horn... and 25 other medicinal herbs.

She made a list and waited for another half hour. The person in front of her had just finished getting their medicine. The proprietress behind the counter was so engrossed in getting medicine that she didn't even look up, just stretched out her hand and said, "Do you have a list? If not, just tell me what you need."

"Do you have 50 catties of each of these medicinal herbs?"

Chinese medicine is usually sold by the gram, so 50 jin (25 catties) is quite a lot. She was worried about not having enough money, so she bought some first and gave it to Shen Qingyan. If it wasn't enough, she could buy more later.

Upon hearing this, the shopkeeper was taken aback for a moment, then took Gu Xixi's phone, looked at the 25 kinds of medicinal herbs, and looked up, "How much? How much do you want?"
