I traveled through the plane space with the trading system

When night fell, Meng Kexin brought Cui'er back to Hangu Pass. After saying hello to her parents, she returned to her room.

As soon as she returned to the room, she opened the system panel and sent some of the fine rice, flour, fruits and vegetables she had collected today to Mu Changfeng.

At this moment, she felt that there were a lot more things in the system warehouse, including gold bars, jewelry, and dozens of high-end cars.

At the same time, I also received a video invitation from Mu Changfeng.

Meng Kexin immediately accepted the invitation, and Mu Changfeng's handsome face instantly appeared on the screen.

Mu Changfeng: "Ke Xin, long time no see, how have you been lately?"

Meng Kexin: "I'm doing fine. I've found my parents and am back with them. How about you, Brother Mu? How have you been lately?"

Mu Changfeng smiled and said, "Thanks to you, I don't have to go on missions anymore. With the magic potion you gave me, I'm invincible in the apocalypse. So, no one dares to mess with me. I used the refined rice and flour you gave me, and the meat from the Tiger King, to open a small shop, and my business is booming every day. Let me tell you a story. This is my personal experience of using the water and food you gave me in exchange for a crystal core."

Meng Kexin nodded, and then heard Mu Changfeng say:

That was the first time my brother used water and rice to exchange for crystal cores. At that time, I was carrying a large bag of rice and flour and a large bucket of water in my hand, and I was struggling to move forward in the ruins of the apocalypse.

My target is a survivor camp. It is said that the people there are willing to exchange crystal cores for food and water.

After several hours of trekking, my brother finally arrived at the camp. I saw a group of haggard survivors sitting around a campfire, discussing how to survive in this apocalypse.

I walked over and explained my purpose. "I have some rice, flour, and water, and I'd like to exchange them for some crystal cores."

When the survivors heard what I said, a glimmer of hope flashed in their eyes. They gathered around me, looking at the food and water I brought with eager expressions.

A survivor named Li Hua stepped forward and said, "We do need food and water here, but the crystal cores are the key to our survival in this apocalypse. We can't give them to you easily."

The eldest brother certainly knew the true meaning of wanting to survive in the apocalypse: "I understand your concerns, but I also need crystal cores to improve my strength so that I can better survive in this apocalypse."

Li Hua thought for a moment and said, "Okay, we can exchange the crystal core for your food and water, but you must ensure the quality of the food and water."

Hearing this, the eldest brother smiled and said, "Don't worry, I brought all this food and water from a safe place. There's absolutely no problem."

Li Hua nodded, took out some crystal cores from his pocket and handed them to me. My brother took the crystal cores, counted them carefully, and then put them in his pocket.

Then he handed the rice, flour and water to Li Hua and said, "You can enjoy these food and water slowly. I hope they can help you get through this difficult time."

Li Hua looked at his elder brother gratefully and said, "Thank you, you are truly our lifesaver."

The eldest brother was of course very happy to help them, so he smiled and said, "You're welcome. We are all people struggling in this apocalypse, and we should help each other."

Meng Kexin: You are amazing, brother. Were those cars and gold jewelry you gave me exchanged for food?

Mu Changfeng: Yes, in the end times, things that cannot be eaten or drunk, such as gold, jewelry, cars and motorcycles, are the most useless and are usually exchanged for crystal cores.

Although the eldest brother no longer needs the crystal core now, others still need the crystal core to improve their abilities, so the eldest brother can act as a middleman in exchange for more supplies.

After all, crystal cores are hard currency here. There are more than a dozen bases of varying sizes here, and crystal cores can be circulated in any base.

It has been seven years since the end of the world here. Who wouldn’t want to taste the food and meat that hadn’t mutated before the end of the world?

Even the military special ability team here wants to recruit me into their group. Isn’t it because they are attracted by my top special abilities and the ability to get food and meat?

So, I really want to thank you. Without you, I wouldn’t have such a comfortable life today.

Meng Kexin: Look at what you said, we have a mutually beneficial relationship. I have also received so many good things from you. And brother, do you still have drinking water? If not, just tell me. I will provide it to you at any time. You can also trade water with them.

"Thank you, sister." Mu Changfeng said with a smile.

Meng Kexin: Oh, Brother Mu, it's not safe out there, so be careful. I heard there are mutant beasts that often appear and attack humans. If you need any help, please let me know.

Mu Changfeng felt warm in his heart. This girl was really kind. He decided that he would repay her well if he had the chance in the future.

After hanging up the video call with Mu Changfeng, Meng Kexin filled all the buckets that Mu Changfeng had sent her with water and sent them to him.

At this moment, Lisa from the magic plane called with a video invitation, and Meng Kexin answered the call immediately.

Lisa: Beautiful little sister, first of all, I want to thank you for providing me with the energy stone, which has greatly improved my magic. May I ask if you still have energy stones? I would like to trade with you again.

Meng Kexin: Yes, but what are you going to trade with me?

Lisa: Beautiful little sister, I have magic weapons here, especially the magic bow, which is very suitable for your plane. It is a long-range weapon and can attack the enemy continuously.

Also, I can provide you with potions for treating external and internal injuries, as well as invisibility and detoxification potions. These are all top-notch stuff.

Meng Kexin thought that when the army was fighting, injuries were inevitable, and healing potions were definitely indispensable. And that magic bow was really a good thing.

Therefore, Meng Kexin did not think too much about it. She exchanged a magic sword for Mu Changfeng and a thousand magic bows for herself, as well as some of the potions that could be used. This transaction left Meng Kexin with few crystal cores, but she still needed crystal cores to support the use of the magic bows.

So she quickly sent a message to Mu Changfeng: "Brother Mu, if you have extra crystal cores, please send some to me. I am running low. Also, I have exchanged a magic sword for you. It is said that this magic sword can exorcise demons and monsters. It will definitely be of great use to you.

It happened that Mu Changfeng was not busy at the moment. When he saw Meng Kexin's message, he sent him a lot of crystal cores below level three without saying a word, and explained the grade classification of the crystal cores.
