After submitting the system, Tongzi and I became famous all over the world

Luosangsang explained with a smile. "We are dimensional merchants. We just happened to come to your dimension yesterday and will stay here for a while. If you have anything you want to trade during this time, you can come over."

"Plane merchants? Aren't you from this world?" Huo Xuan immediately reacted and asked.

"Yes, we are just passing by. Do you want to come in and take a look?"

After listening to Luosangsang's words, Huo Xuan glanced around the store. There were transparent glass walls in the room of more than 100 square meters. There was a huge three-dimensional cabinet at the door, and no one knew what it was used for. On the other side was a counter and a rest area. The rest of the place was filled with shelves of goods, and all kinds of things were neatly placed on the shelves, filling up.

"Oh my god, Captain, Captain!! I saw Coke, potato chips, and spicy strips, ahhhhh!!! They are all my favorites!!"

Seeing these, Chen Lin couldn't help but shout loudly, and the other people behind him were no less excited. These were things that could only be eaten before the apocalypse. In all the years since the apocalypse, they had never seen them, and hadn't eaten them for a long time.

"Sorry, I'm so excited to see so many things from before the apocalypse at once. These are my teammates. They are Chen Lin, Ye Cheng, Wang Tao, and Zhang Rui."

Huo Xuan pointed at the team members behind him and introduced them one by one, then he thought of something and asked.

"What do you need to trade?"

"Anything is fine, but you can only know its value after exchanging it. Gold, silver, jewels and accessories are all fine. Put the items into the exchanger at the door, and trading coins will appear. Then you can buy things in the store." Luosangsang said, pointing to the exchanger.

"Gold and silver jewelry can also be exchanged?" Chen Lin looked at Luosangsang in surprise.

After all, in today's world, apart from food, everything else is worthless, not to mention gold and silver jewelry, which are everywhere on the streets. They usually don't pick them up when they see them. After all, it's hard to get enough food, so who would bother to dress up?

"Yes, if you have any, you can bring them here to exchange."

"Can this be exchanged?"

Huo Xuan took out a red diamond-shaped gem the size of a coin from his pocket and asked Luosangsang and the other two.

Lu Chenyu took it, and the three of them looked at it curiously, but they couldn't tell what it was.

Luosangsang asked: "What is this? A gem?"

"This is a crystal core, a level one, taken out from a zombie's head. The red one is a level one fire crystal core. The color represents the attribute of the superpower. I have a level seven thunder purple crystal core, Chen Lin has a level six fire red crystal core, Ye Cheng has a level six gold yellow crystal core, Wang Tao has a level five wood green crystal core, and Zhang Rui has a level five water blue crystal core. There are also space, light, darkness, and spirit crystal cores. But these types of crystal cores are hard to come by, and we also need crystal cores to upgrade." Huo Xuan explained it to them in detail.

"Wow!"

Chen Yanxuan exclaimed excitedly.

Luosangsang and Lu Chenyu also came back to their senses from their surprise. They thought that it was the end of the world, so it was not surprising to have superpowers. It turned out that the novels she had read before did not lie to her. This was the absolute reality.

"Of course you can, but I don't know how many trading coins you can exchange for. You can go and try." After saying this, Luosangsang returned the crystal core to him, indicating that Huo Xuan could go and try.

Huo Xuan took the crystal core, walked to the exchanger, and placed the first-level crystal core in his hand into the plate in front of the trader. A white light flashed, the crystal core disappeared, and a line of words appeared on the screen above.

[Huo Xuan, Level 10 Fire Crystal Core, Trading Coins.]

The teammates saw a number 10 suddenly appear above their captain Huo Xuan's head. It was magical and interesting. However, they were all very happy to see that they could be exchanged for trading coins. After all, they didn't need low-level crystal cores anymore. They needed high-level ones to improve their superpowers. They could just exchange all the ones in the base. Food would be more delicious. And as mentioned earlier, gold and silver jewelry could also be exchanged. They could just go and collect some.

Thinking of this, they all took out the crystal cores they had with them. Although they handed in the crystal cores to the base every time they hunted, they would occasionally keep some, which they could use to exchange for something to take back.

So they pushed aside their own captain who was blocking the trading machine, and took out the small bags of crystal cores in their arms and poured them into the exchanger.

【陈林，一级水系晶核10交易币、四级木系晶核200交易币、二级火系晶核30交易币、三级木系晶核100交易币…….】共兑换1000交易币。

[Ye Cheng, first-level fire crystal core 10 trading coins, first-level wood crystal core 10 trading coins, second-level fire crystal core 30 trading coins, third-level...] ​​A total of 800 trading coins are exchanged.

[Wang Tao, 30 trading coins for the second-level water crystal core, 10 trading coins for the first-level water crystal core...] A total of 750 trading coins were exchanged.

[Zhang Rui, second-level wood crystal core 30 trading coins, second-level water crystal core 30 trading coins...] A total of 700 trading coins were exchanged.

…………..

After the exchange, Luosangsang and the others roughly knew the exchange value of the crystal core. The first-level crystal core was 10 trading coins, the second-level crystal core was 30 trading coins, the third-level crystal core was 100 trading coins, and the fourth-level crystal core was 200. However, they didn't know the value above that because the highest level they could exchange was the fourth level. After all, the fifth-level crystal core had to be kept for upgrading their superpowers.

But from this point of view, the higher the level of the crystal core, the higher the exchange value, and the more energy contained in the crystal core.

After the exchange, they rushed to the shelves together and picked out the snacks they had just liked. There was a transparent protective cover on the shelf, probably to prevent people from stealing. Seeing that the shop owners ignored them, they knew that this protective cover was definitely not simple. Sure enough, after purchasing more than their trading coins, they could not touch the goods because they were blocked by this transparent protective cover.

But they were also very happy. After all, it had been eight years since the apocalypse. Basically, those who could activate their superpowers had already done so, and those who couldn't could only accept their fate. Although life was difficult for ordinary people in this world now, they could still survive with a little effort.

Except for the nine-level strongmen in the three major bases, most of the psychics have reached level five and six, and the lowest are level three and four, so the one and two level crystal cores are basically useless. Even if they are used to exchange for supplies, they can only get a little food, and they may not be able to eat enough. Now, these can be exchanged for food, and life in the base will be better.

Chen Lin, holding a bunch of snacks, said happily to Luosangsang and the others, "This is too cheap. I haven't had potato chips or Coke for a long time. I'll go out hunting and come back to buy more later!"

"Sure, just exchange whatever you want to buy and take it yourself."
