The end of the world: Refresh information every day, stock up on the goddess and stock up on supplie

But Ye Tong said that crystal cores can also be used to make items. What does that mean?

Chen Senyan couldn’t understand all this, he just felt that the woman in front of him was not simple.

"If I'm not mistaken, this box should have the crystal core embedded in it using a special method, and it should have some special abilities." Xue Feng said.

After these words were spoken, Chen Senyan was even more surprised.

Why did Xue Feng know?

And when he saw Ye Tong's expression change slightly, Chen Senyan knew that Xue Feng was right.

Could it be that similar technology already exists in the riverside villa?

Thinking of this, Chen Senyan couldn't help but get excited.

I even felt that coming to the riverside villa was an extremely correct decision.

There are a lot of rumors in the base now.

One of them is that at the base, there is a new technology.

It can greatly improve human physical fitness and reach the level of superpowers.

Chen Senyan initially thought that this was just a rumor.

But soon Chen Senyan also discovered that this seemed to be true.

Because there were more than a dozen guards in the base before, and now they have all been transferred away.

These guards were elite, but no one knew where they were transferred to.

I just know that some people followed Qin Fengshan.

The rest are all inside the base, in a special place for training.

Some people have seen these people display extraordinary abilities inadvertently.

Chen Senyan was there when Qin Fengshan left the base to carry out the mission without Baldhead.

I once tried to find out about this matter from Qin Fengshan in a roundabout way.

But every time Qin Fengshan had a stern face and told people not to ask questions that they shouldn't ask.

Although Qin Fengshan didn't say anything, Chen Senyan could tell based on Qin Fengshan's attitude.

There is definitely something going on here!

Now Xue Feng actually told the secret of the item in Ye Tong's hand.

How could Chen Senyan not be excited?

This proves that Xue Feng should have mastered, or at least knew part of, the secret.

"I have to admit that you are quite good at guessing. This is indeed an item that has been fused with a crystal core." Ye Tong nodded slowly.

But Ye Tong didn’t think that Xue Feng knew the technology in this area.

I think Xue Feng is just guessing.

But Ye Tong had to tell Xue Feng this information anyway so that she could make the exchange.

It doesn’t matter if you say it directly now.

"A blind guess? I have something similar in my hand." Xue Feng smiled.

"This is impossible!" Ye Tong immediately denied it.

As far as she knew, Jiangcheng did not have this kind of technology.

Of course, the information Ye Tong obtained did not come from inside the riverside villa.

The New Century Chamber of Commerce has special surveillance methods.

At least not from a distance.

"Really? Then let me show you something."

Xue Feng directly smashed something onto the table with a chopping motion.

The originally smooth table top immediately had a crack.

It's like something is embedded in it.

"What the hell?"

Chen Senyan couldn't help but exclaimed, he didn't see anything.

But judging from the noise just now, there is indeed something on the table.

Ye Tong was even more unconvinced and reached out to touch it.

"what!"

But the next second, a wound appeared on her finger.

Blood immediately gushed out and he immediately withdrew his hand.

"You should be careful about things you can't see." Xue Feng smiled slightly.

Then he reached out and touched it.

The next second, the invisible thing returned to its original shape.

It’s actually a nano axe!

But the nano axe this time is slightly different from before.

There is an additional walnut-sized crystal core on the handle of the nano axe.

It is directly inlaid.

It seems to be integrated with the entire nano axe.

This is the reward that the system gave to Xue Feng before.

Originally, Xue Feng planned to use it when the time was right.

But this time I met Ye Tong!

The other party actually knows this technique!

So in order to overwhelm the other party in the negotiation, Xue Feng just chose a mutant crystal core.

Embedded on the nano axe.

It was a third-level crystal core, a third-level mutant that once broke into Song Yan’s bathroom!

The reason why Xue Feng chose this is because the nano axe itself is sharp enough.

I can also add lightning power to it!

There is no point in enhancing the strength attribute any further.

It would be better to add some auxiliary functions, such as invisibility.

In this way, no matter whether it is a human or a monster, no one can see clearly what Xue Feng is holding in his hand.

At the same time, the method of use also appeared in Xue Feng's mind.

It’s actually very simple, just inject energy into it.

It can trigger the power of the crystal core.

In fact, Xue Feng knew nothing about this technology, but it did not affect his pretending to know it.

"Can I take a look?" Ye Tong looked at the nano axe with a frown.

Obviously she had to try it herself to be sure.

"Of course." Xue Feng nodded.

Ye Tong took a deep breath and ignored the wound on his finger.

Bring the nano axe in front of you.

She couldn't tell what the axe was made of, but it seemed very hard.

Try to input energy into it.

Sure enough, the shape of the nano axe gradually disappeared.

"I didn't expect that you also mastered this technology, and even better than ours!" Ye Tong sighed heavily after putting down the nano axe.

"Although that's the case, I don't mind trading with you. Our production is limited." Xue Feng smiled slightly. Now the initiative is in his hands.

Then Xue Feng directly asked what the function of the wooden box on the table was.

And its price!

Ye Tong explained with a somewhat lost expression.

The wooden box on the table is fused with a second-order crystal core and has a space storage function.

It can store about five cubic meters of items.

"As for the price, one sixth-level crystal core, or seven fifth-level crystal cores." Ye Tong said directly.

"This is equivalent to exchanging a second-level crystal core for a sixth-level crystal core. This is a good deal." Xue Feng sneered.

Although second-order mutants are not everywhere, they are not difficult to find.

But the sixth-order mutant is different!

The two level-six mutants killed by Xue Feng were both tough guys!

One that triggered a tide of zombies in Jinling City.

Another one was in Xinzhen, causing quite a stir.

If we want to deal with them, I don’t know how much manpower and resources will be consumed.

Now I want to use this thing to exchange for a sixth-level crystal core.

I can only say that the New Century Chamber of Commerce is a ruthless person.

But Ye Tong suggested that five fifth-level crystal cores would also be an option.

It seems that the value of seven fifth-level crystal cores should be equivalent to that of one sixth-level crystal core.

This is roughly the converted price.

"Don't think that this is just a second-level crystal core, but the variants of space-related abilities are also very rare, and the craftsmanship..." Ye Tong was about to say that the craftsmanship is unique.
