Shen Qingqing quickly registered her store according to her memory from the previous session, and then uploaded the vegetables she grew.

She remembered that in the last time, the vegetables and grains grown in the space were very popular in some wasteland worlds and the end worlds.

Although she didn't know the difference between these worlds and hers, she was happy as long as her things could be sold.

When trading here, she can exchange with the other party, and can also use the material coins that come with the mall to make purchases.

Shen Qingqing didn't have any material coins at the moment, so she planned to sell some vegetables first. Who knows, the mall might have what she needs.

Shen Qingqing set the price according to the type of vegetables, and after setting it, she left the space. If someone needs it, they can directly use the material coins to buy these vegetables.

Even if you don't have material coins, you can send her a message and exchange it for other things.

Almost on the same day that Shen Qingqing set the transaction price, all the vegetables in her window were sold out.

Shen Qingqing, who had left the space, knew nothing about this. When she found an opportunity to sneak back into the space, she was stunned to see the empty inventory on the trading panel. Then she looked at the supply coins on the upper right corner and saw that she already had thirty gold coins.

Shen Qingqing quickly checked the sales records in the background and found that almost all the goods she put on the shelves were bought by a space master from the wasteland.

This is a big deal. Shen Qingqing was so happy that she couldn't stop smiling. She immediately transferred another batch of vegetables from the warehouse to the shelves. Because her current trading system level is low, her window only has three trading columns, and the upper limit of each trading column is ten, so she can only put thirty kilograms of vegetables on the shelves each time.

Fortunately, she set the vegetable unit according to the weight rather than the number of pieces, otherwise she could only put a maximum of ten vegetables on each trading column.

Shen Qingqing couldn't help but feel lucky for her foresight. Because Shen Qingqing's alien trading system had just been opened, many functions had not been launched, and many inventory columns were gray, which meant that she could not use this function yet.

However, Shen Qingqing was not discouraged. Based on her previous experience, when her transaction amount reached one thousand and the number of transactions reached thirty, the system would automatically upgrade and add two more trading item slots.

In order to upgrade the trading system as quickly as possible, Shen Qingqing would sneak into the space whenever she had time to check the trading volume and amount. For such items, if there was no obvious difference in quality, the price could only be set once. Therefore, Shen Qingqing's vegetables were always sold at the price of one material coin per kilogram.

At first, she only put cucumbers, peppers and rapeseed on the shelves. But after several transactions, the space master of the wasteland world on the other side took the initiative to send her a message, hoping that she could put more other vegetables or food on the shelves, preferably seafood.

Shen Qingqing thought about it, and then put two more kinds of grains, rice and wheat, on the shelves. So her window now has five kinds of goods. However, because the inventory can only hold three items at a time, Shen Qingqing has to go out of the space frequently to check and replace the goods.

While she was working hard to increase the trading volume, Zhou Yuanzheng keenly noticed his wife's unusual behavior in recent days.

In the past, although she was busy during the day, she had plenty of time after work, and the two of them could spend time together every night. But recently, she always disappeared suddenly, or found various excuses to sneak into the study. In short, the time she spent with him was very little. There were even several times when they were talking, Shen Qingqing suddenly said that she had something to do, and then left him alone.

Shen Qingqing was completely unaware of Zhou Yuanzheng's resentment, and instead became more focused on her own space trading system. Every time she entered the space, she could see the increasing amount of material coins on the trading panel, which made her very happy, so she left the space more frequently. She was so focused on improving the level of the trading system that she ignored Zhou Yuanzheng, the man next to her.
