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

The man used his other hand to press down on her door, pulled it open forcefully, and shoved her backward, trying to come in!

Gu Xixi screamed in fright, abandoning her takeout and struggling to break free while pulling hard on the door. However, with her small frame and strength, she was no match for the man outside.

She also clearly saw the yellow uniform on the man opposite her; he was a food delivery worker.

"Help! Help! Fire!" she shouted, but the man became enraged and kicked her in the shin, causing her to kneel down as he entered the room.

The man closed the back door, picked up Gu Xixi like a chick, and said fiercely, "How many times have I called you and why didn't you answer? Huh, you stinking bitch, which simp you fooled into ordering takeout for you again!"

What nonsense! Gu Xixi was terrified, afraid that he would hurt her. So she could only suppress her anger and grievances and try to remain calm, saying, "Are you having some trouble? Tell me, and I'll see if I can help you."

You're dead once I'm out of danger!

The man was taken aback, then actually put her down. His lewd gaze swept over her. Gu Xixi's mind raced as she searched for a solution, and she mentally asked, "System, System Bro, save me!"

"Hey girl, come down and pick up the goods!" Uncle Wang's son, Brother Wang, who was in charge of delivery, drove up in his truck and shouted. Gu Xixi didn't hear what the system said, but both she and the man in front of her changed their expressions.

Seeing that the man was about to go berserk, she immediately kicked him in the groin, and taking advantage of his momentary lapse in attention, she opened the door and rushed out, shouting, "Brother Wang, help! Someone is holding me hostage!"

She ran out crying, and Brother Wang and the people behind him who were preparing to unload the goods suddenly changed their expressions and immediately took out wrenches and other tools and walked into her yard.

"Don't be afraid, there are two of us..."

He had just cautiously reached out to pull the door open when the man inside charged out like a bull. After a struggle, he finally managed to subdue him.

The man started crying and begging for mercy again. Gu Xixi was still in shock and immediately called Uncle Hat. She sat there, feeling lingering fear, waiting for Uncle Hat to arrive.

Just fifteen minutes later, Uncle Hat arrived at the door in his "Ur-Ur" car. Upon seeing Gu Xixi, he was overjoyed and exclaimed, "It's you, little sister! Where are the thugs?"

Gu Xixi recognized the man as the same young man who had greeted her when she delivered the book, but she couldn't smile now; she felt even more aggrieved.

Pointing to the tied-up man, she said, "I ordered takeout more than an hour ago and noted that it could be left at the door, but he insisted on waiting until now, saying that I didn't answer the phone. He attacked me while I was getting the takeout. Luckily, Brother Wang arrived quickly...!"

"Okay, I understand your grievances. Let's go to the police station and clear things up. Don't be afraid."

The sound of 'Ur-Ur' faded into the distance, and the group followed. It turned out that the man had been penalized for being late with many deliveries that day, and when he discovered that she was a girl, he wanted to take the opportunity to vent his anger.

This infuriated Gu Xixi, who insisted on severe punishment and refused to accept apologies or compensation. However, Uncle Hat still advised her to settle the matter privately. It wasn't that the punishment wasn't enough, but that if they really pursued the matter, he wouldn't be able to punish her for many days, and it would be easier for him to hurt her again out of hatred.

Gu Xixi had no choice but to give up in the end, feeling frustrated and upset once again about her useless physique.

[System, give me another cheat code! I want to learn the martial arts of ancient heroes, like leaping across rooftops and killing ten people with a single punch. Next time I encounter a scoundrel like that, I'll cripple him!]

The system didn't waste any time, and its gentle, clear announcement sounded again: [To help the host become a qualified interdimensional trader, a learning package is being prepared for the host. The first manual, "Strengthening the Body and Improving Physical Techniques," is now being distributed. Those who practice and master this manual will experience rapid recovery of their physical attributes, achieving the elimination of all ailments and a strong, healthy body within two months. After completing the first manual, you can begin learning martial arts.]

Great! Gu Xixi felt much better and planned to practice as soon as she got back.

Brother Wang and his friend were giving statements in another room. Gu Xixi was about to leave when the guy in the hat from before came in again. "Don't rush out yet, I have something else I want to ask you."

Gu Xixi sat down again and drank her tea.

"Do you remember the medical book you sent before? I showed it to Professor Xu, the president of the Chinese Medicine Association, and he said it was genuine. We went to your house to look for you before, but we couldn't find you there, so I want to know more about the origin of that book. Also, could we arrange another time to meet with Professor Xu?"

"By the way, my name is Xu Yi, you can just call me Brother Xu."

So those two people at the supermarket entrance were them. Gu Xixi realized that it was really difficult to face so many unknown dangers in the world alone in the future.

Moreover, if it's about exchange, she can't handle the procurement of supplies in the real world on her own... If she were to align herself with the country, she could benefit from having a powerful backer, get rich, and maximize the value of the system, achieving a win-win situation.

[Brother Tongzi, may I expose you?]

[Please do as you please, as long as it doesn't interfere with completing the Multiverse Trading Journey mission!]

With the system's approval, Gu Xixi had no more concerns. She got up, closed the door, and looked very serious. Xu Yi also became serious.

His great-uncle said that anyone who could produce this book but came from an ordinary family must have had a distinguished ancestor. There were some secrets that couldn't be shared, so he had to be careful not to say anything that might offend someone.

Gu Xixi's current caution must involve some secrets.

"You said it, I will never tell anyone!" He patted his chest and promised. Gu Xixi nodded, lowered her voice, and said it clearly, word by word.

"A few days ago, I awakened a system called the Multiverse Trading System, which requires me to go to three thousand planes to be a merchant and carry out trading tasks. The book 'Qianjin Fang' was an item that the ancients of the first world gave me to exchange for goods."

After saying this, Xu Yi froze, staring at Gu Xixi with a head full of questions. Had this child's brain been damaged by fright?

Looking at Xu Yi's expression, Gu Xixi realized he was indeed stunned.

"It's not just medical books, but also calligraphy, paintings, antiques, and gold nuggets. I'm thinking, if a world can be exchanged for so many valuable things, does that mean our country across the three thousand planes is going to get rich? I've thought about it for a long time and decided to hand myself over to the country. You should go and report to the higher-ups as soon as possible."

Xu Yi: ...

The two stared at each other. Xu Yi's face began to contort as he inhaled, as if he were holding back something. After a long while, he regained his composure and spoke seriously.

"Actually, I also awakened a system called the Lie Detection System. I can tell who is lying at a glance."

Gu Xixi: ! !

These days, are these systems mass-produced? Everyone has one!
