Chapter 243

As soon as Xu Zi'an returned to Brilliant Island.

He saw a small unmanned delivery box floating at the entrance.

No need to guess.

This must be his spoils of war.

Opening it, sure enough, it contained a palm-sized Cat Star Stone.

This thing is worth five hundred million.

And don't look at it being only palm-sized.

In reality, because of its properties, just a tiny bit can improve the rigidity of an entire cruiser.

It is definitely a rare natural treasure.

It's just a pity...

The system does not add wealth value for this thing.

But it doesn't matter.

And speaking of this natural treasure.

Xu Zi'an suddenly remembered.

The day he first moved into Brilliant Island.

He seemed to have bought a full 700 points worth of natural treasures for tempering his physical body.

During this time, he was either busy obtaining evolution points or busy with starship evolution.

He had actually forgotten about it.

But now that he had enough time, it was just right to try using the natural treasures to temper his body!

The physical body is Xu Zi'an's biggest weakness.

And with the tempering of natural treasures.

When he becomes even stronger in the future.

Maybe even a cannon shot hitting him wouldn't necessarily kill him.

He immediately took the items and returned to the island.

Looking at the Cat Star Stone in his hand, Xu Zi'an felt.

He needed to build a dedicated vault.

He didn't want these good things to be lost or stolen.

It's not that he can't put them on the Cui Can.

Even if he isn't personally near the Cui Can, it's fine.

A biological starship is called a biological starship for a reason.

It is that mental connection with the biological captain!

And this mental connection is not limited by distance.

For example!

Xu Zi'an is currently on Earth in the Milky Way.

And the Cui Can is placed on the accommodation planet.

Suppose the accommodation planet is suddenly attacked at this time.

Then the star crystal brain on the Cui Can would instantly analyze the situation and transmit the situation here to Xu Zi'an.

And Xu Zi'an, far away in the Milky Way, could also synchronously receive this transmitted message and directly control the Cui Can to escape or fight with his mind!

This is also one of the main functions of the Excellent-grade red Xiannian series star crystal brain!

It is even more of the terror unique to biological starships!

Of course, pure mental control is definitely not as good as when the person is personally piloting the starship.

The combat effectiveness, flexibility, and all other aspects are much worse.

Basically, it is impossible for anyone to remotely control a starship to fight.

At most, they would only control it to escape or something similar.

But that is enough.

This is the huge difference between biological starships and mechanical starships!

The matter of the vault.

We'll talk about it later.

Now let's go check out those natural treasures first!

Things like natural treasures.

Xu Zi'an definitely keeps them in the storage room inside the villa.

Arriving at the storage room, he found a place to put the Cat Star Stone.

He then conveniently took down those natural treasures.

Because of the high cost of natural treasures.

Even with 700 points, Xu Zi'an actually only bought two types.

One is a plant called 【Wang Xinghua】, and the other is a plant called 【Steel Bone Grass】.

These natural treasures that strengthen the body and increase biological energy.

The vast majority come from plants.

Only a very small number are non-plant items.

Wang Xinghua looks quite similar to a sunflower.

It likes shade.

Because its vitality is extremely fragile, even in the interstellar era.

This kind of thing is extremely, extremely difficult to cultivate artificially.

Even if artificially cultivated, it is the kind with very small quantities and extremely high costs.

In reality.

Almost all natural treasures.

Are very difficult to cultivate artificially.

After all, if they could be cultivated artificially on a large scale...

Then they wouldn't be natural treasures, would they?

They would be things every household could eat as vegetables.

Steel Bone Grass looks quite strange.

It is segmented, like bones.

And because its effect is indeed able to strengthen human bone density, it is named accordingly.

It's the same principle as drinking milk to supplement calcium, and supplementing calcium strengthens bones.

These things...

Nowadays, they could have been explained by science long ago.

If placed in ancient Earth hundreds of thousands of years ago, they could probably be treated as fairy herbs or something?

Hmm, probably.

Since these things were bought back, Xu Zi'an hadn't opened them to look.

Of these two natural treasures, the Wang Xinghua is worth 400 points.

The Steel Bone Grass is slightly cheaper, worth 300 points.

Both are packed in alloy freshness-keeping boxes.

He excitedly opened one of the boxes.

What met his eyes was a plant that was still fresh, with a flower shape similar to a round sunflower.

Natural treasures, although humans cannot cultivate them on a large scale, small-scale artificial cultivation is possible, but the cost is too high.

However, there is absolutely no problem in how to ensure the freshness of natural treasures.

Let's put it this way.

The Wang Xinghua in his hand is still in the state it was in when it was dug out of the soil.

Even though its vitality is extremely fragile, using this kind of alloy freshness-keeping box to ensure its life is frozen at the moment it was dug out is no problem.
