"It's a one-off, it's a bit of a pitfall. Xu Yi didn't expect that this could only be used once.

He naturally knew that telekinesis could not be absorbed.

It's a surprise to be able to use it like this.

"It's good for once, at least it can give us a way to deal with the beast. Xu Yi, your contribution is too great and deserves to be remembered by all of us. One of the challengers said excitedly, he was going to give up and leave.

"It's hard to get some, but it's still available. The wasteland, yes, we can go hunt those beasts in the wasteland, they have this brain crystal, right?" The other challenger had an idea, and hit the beasts in the wasteland.

"By the way, does that killer melon have a brain crystal, has anyone seen it, and where is it?" asked a challenger curiously, feeling that plants were relatively easy to obtain.

"Here, here I am, this thing. As he spoke, someone raised his hand.

The brain crystal is not big, only the size of a five-cent coin.

"When you use it, just inject your telekinesis into it. If you don't use it, the telekinesis inside should be maintained for a long time. Xu Yi explained.

"This brain crystal can become our currency. After all, you always need to trade. More than anything else, we need this brain crystal. Judging by the situation just now, a single brain crystal should be able to kill a few fierce beasts, right?" Jerry said excitedly, he had been thinking about how to build a currency system so that he could trade with other challengers.

This brain crystal is completely natural currency!

After all, everyone needs it.

"Yes, it can be used as currency. More than anything else, this brain crystal is more valuable. We can also use it to research weapons, energy guns like lightning guns, and telekinetic guns. Qin Fan also agreed, if it weren't for Jerry's quick talk, he would also suggest that everyone use this brain crystal as currency.

For the person who took away the killer melon brain crystal, everyone didn't say anything.

After all, at the beginning, everyone didn't know that there was such a thing as brain crystals, and they didn't know what it did.

"Xu Yi, I want to ask. People, do we humans have brain crystals?" A challenger asked curiously, after all, even plants have brain crystals, can humans have them?

"Probably not, at least not in my brain. "Xu Yi really can't be sure, maybe it will grow over time.

"Alright, now you can continue to look for water. With that, Xu Yi clapped his hands, and then returned to his team.

Knowing the existence and role of brain crystals, everyone really rekindled hope.

At this time, in the Eliminator camp, more than a dozen Eliminators gathered together, especially regretting that they had given up.

"This brain crystal, did Xu Yi discover it a long time ago, or did he just discover it?" an eliminator said with some distress, he felt that if Xu Yi had announced the news earlier, he would not have given up.

At that time, although he was bitten by a ferocious beast, it was not fatal, and he should be able to return to normal in a few days of recovery. After giving up, it will take at least a month to recover when you come back.

So he regretted that he had given up even more, if he was still in Linglanxing, he would have been alive and kicking a long time ago, and he didn't have to sit in this wheelchair like now, and there was no way to stand up.

"It should have just been discovered, he has just awakened his spiritual power for a long time, and it is not easy to find this major news. Another eliminator said.

"I wish the time had passed sooner, and by the 200th day, we would be able to return. When I came back, even my mental power was gone, and I was uncomfortable. "The one who spoke was given up yesterday, and the one who had already stimulated the mind. But when he returned, he found that his mental power was gone.

"If you don't give up and regret it for a while, give up and regret it for a lifetime. The other person, who also gave up yesterday, said a sentence with a face full of regret.

"Let's think about what we should bring back with us. Now that the brain crystal has become currency, we can exchange materials for currency. ”

The appearance of the brain crystal not only affected the challengers of the Spirit Blue Star, but also affected the eliminators, and affected the alliances of various countries.

Natural currency is still very different from issuing currency, and they also customize some plans to deal with the emergence of brain crystals.

But these things have nothing to do with Xu Yi and them.

The most important thing for them at the moment is to find a source of water and a suitable place to build a camp.

"Xu Yi, is there a difference between the strength and weakness of the brain crystal?" Su Yan walked to Xu Yi's side and asked curiously.

In the past, she felt that she should know Xu Yi very well after watching Xu Yi's live broadcast for so long.

However, it is ridiculous to find that I am confident now.

Xu Yi said a few days ago that he had awakened his spiritual power less than 50 days after entering the live broadcast. However, even the organizers have just found out.

She didn't know Xu Yi at all.

What she understands is only some of the situations that Xu Yi has shown. He hid it, and no one would know.

She wondered, though.

"I don't know, I've not seen many brain crystals. But I feel that there should be a difference. "Xu Yi only has spiritual power, not a perspective eye, and can see through everything.

"Then we can get the brain crystal in the future, can I study it?" Su Yan then asked, she was also very curious about the brain crystal, thinking that if she could unlock its secrets, she might be able to quickly enhance the human telekinesis.

The use of brain crystals is always with the help of external forces. If you want to be really strong, you still have to make your strength stronger.

"Absolutely. Xu Yi smiled slightly, this is a good thing, Su Yan is a doctor after all, and he is also a brain department. Maybe there's something special to be discovered here.

If you want everyone to improve, he can't do it alone.

"Water, I hear the water. One of the challengers shouted excitedly, and then sped over.

Behind him, there are plenty of challengers on his heels.

Did you really find water?

Xu Yi was a little puzzled, and he also sped up with the others.

However, he soon heard screams.

It wasn't the sound of water at all, but the sound of the beast, which made him mistake us for the sound of water.

Moreover, not just one or two, there are a total of 6 fierce beasts.

One of the challengers had his arm bitten off and was on the run.

The others hurriedly rushed forward.

"Brain Crystal, the person with Brain Crystal, hurry up. Someone in the crowd shouted.

One fierce beast made everyone a little powerless to deal with before, and there were 6 of them at once, which was definitely a huge crisis for the challenger.
