"By the way, I have a plant called Tianjingcao here. It is said that it can purify water and soil. I don't know if it is useful for your situation." Chen Xiayue took out a pot of Tianjingcao and handed it to Zhou Mingxu. He looked.

"I heard that most of the land on your plane is infected with zombie virus, and I don't know if it can be purified by qualified Tianjing Grass. Do you want to try?"

Zhou Mingxu looked at the crystal clear plant in front of him in surprise, with a look of suspicion and anticipation on his face, "Is what you said true?"

"According to the introduction of Tianjingcao, it can purify land pollution and water source pollution, but I don't know if zombie virus infection can be purified. But you can also buy one and try it out to see if it can be purified."

"By the way, the water purified by Tianjingcao is fresh water. Don't think about planting it in seawater. If you want to purify seawater, there is a plant called Chlorella on my side. It is a It can purify sea water.”

"How? Do you need it?" Chen Xiayue asked.

"How to sell Tianjingcao?" Han Zhengting asked.

"Tianjingcao is 150 yuan per plant." Chen Xiayue said.

"Two first-class crystal nuclei, I bought this Sky Pure Grass." Han Zhengting said.

Chen Xiayue waved her hand and said, "Tianjingcao is really worth 150 yuan. If you have two crystal cores, I will give you something worth 50 yuan."

Han Zhengting had no objection, and took out two first-class crystal cores from his pocket and handed them to Chen Xiayue.

Han Zhengting and Zhou Mingxu continued to move out the various supplies they bought. After all the purchased things were moved out, Zhou Mingxu left the store holding the flower pot of Tianjingcao.

Chen Xiayue looked at what she received today. She couldn't exchange crystal cores and gold jewelry now. She sold the crystal cores directly to the system, and then the gold jewelry was kept in the system warehouse for next month. Go to Sanya to exchange, and then pay back the money and pay taxes.

Even though her shop is just a small grocery store, even though most of her customers are from other worlds and other planes, she still has to pay taxes. She is a good citizen who abides by the law.

Chen Xiayue continued to look at the magical plants in the system mall, and then she planned to replace the street tree in front of her store with the Yunling tree. After all, the Yunling tree can generate aura, and a place with good aura has good air and a good environment.

Chen Xiayue looked at the crystal cores she received today and was able to buy three Yunling trees, and then replaced the street tree in front of her store, and replaced the other two with the two trees in front of and behind the village of her grandfather and grandmother in their village. Tree.

The leaves of the Yunling tree are not much different from ordinary big trees, so even if the system helps her replace the original tree with the Yunling tree, there is no need to worry about someone finding out.

After replacing the Yunling Tree, Chen Xiayue was satisfied.

She happily started to organize things. Fortunately, most of what Han Zhengting and the others bought today were food and water, and they rarely bought things such as seasonings, drinks, biscuits, and daily necessities, so she didn't need to work hard to replenish them. It can be moved directly from the warehouse.

[System, I’m really helpless with such a large amount of purchases, can you give me a channel for purchases from the system mall? 】 Chen Xiayue asked.

[Just like food, if I buy a lot of goods, it will definitely attract attention, can you help me? 】

[You didn't have this idea to hand over the grocery store system? If your actions arouse the attention of the relevant departments, and then find out the abnormality of your store, then you can report the incident of the grocery store? ] System Road.

[But I am afraid that before the grocery store is handed in, I will be invited to have tea or go in. 】Chen Xiayue said with a sad face.

【You didn't break the law, what are you afraid of? 】

When Chen Xiayue heard the words, she thought, yes, why was she afraid that she didn't break the law?

[However, food is indeed a problem. It is better for you to buy some grains often, such as sweet potatoes, potatoes and corn. I will give you the contact information of the planting base, so you can buy from this company. ] System Road.

[Thank you, system, you are such a good system. 】

[I don't know who it is, I was said to be a garbage system before. 】

【how could be? The system is so cute, you are the best system in the entire universe. 】

【…】

Chen Xiayue joked with the system for a while, and the time slowly reached 11:30. The plane store was closed, and she should go back and have a good sleep.

When Han Zhengting and the others went back, they were welcomed by the leaders of the entire base, because they exchanged too many things.

Although it is said that tens of thousands of things are not too much, it is more to replace them with food. A 50-pound bag of rice costs 95 yuan, and 20,000 yuan can buy more than 200 bags.

Although they did not buy more than 200 bags of grain this time, they bought enough rice, flour and water, which made everyone very happy.

You must know that when they go out to find supplies, they have to guard against zombies and other people who go out to find supplies.

But now, you only need to exchange first-class crystal cores and gold jewelry, which are worthless in the apocalypse, isn't it gratifying to be so relaxed?

"You two are great." Han Song couldn't help but said happily. Originally, he wanted to pat Han Zhengting on the shoulder, but seeing his son's expressionless face, he could only pat Zhou Mingxu.

Zhou Mingxu smiled and nodded, "By the way, the lady boss told us something just now."

Zhou Mingxu told the leaders about the rice crackers, salt crackers, oil crackers, bread crackers, and steamed bread crackers mentioned by Chen Xiayue, and wanted to ask them if they wanted to buy these magical plants.

Their northwest side has less water resources after the end of the world. If it wasn't for those with water system abilities, they might not be able to live well. However, most of them have no water to drink.

Zombie viruses are really pervasive, both land and water sources are polluted, and even the southeast, southwest and other places with abundant water sources in the south have little water to drink, let alone the northwest?

Water is one of them, and there are very few oils and salts.

It is really difficult to obtain salt now, and the ocean also contains zombie viruses. Sunbathing and other things may also cause viruses to remain in the salt. Inland well salt and mineral salt are also polluted, and it is more difficult to find a salt mine that is not polluted.

And the salt fruit that Chen Xiayue said really made them very excited. The salt that is indispensable to the human body is very important. In the last days, salt and food are definitely the most valuable things in the world.

"By the way, this is what Boss Chen sold to us, it's called Tianjingcao." Zhou Mingxu put the flowerpot on the table and said, "According to Boss Chen's meaning, this Tianjingcao can purify water and soil and can be planted on land. It can be planted in water.”

"Why don't we try planting it in the river water and see if it can purify the river water infected with the zombie virus?" Zhou Mingxu said.
