Evolution from the crocodile

Seeing the other party staring at the treasure, the Lizard King felt a little regretful.

Lord Dragon King, if you are interested, I am willing to give you 10 gold bricks, no, twenty gold bricks... it answered cautiously, with a bit of pain on its face.

This guy... Lu Chen was speechless again.

He is guarding thousands of tons of gold, but he is only willing to give himself a few pieces, which is really stingy.

But Lu Chen really wasn't interested in this thing, so he simply refused.

The Lizard King secretly breathed a sigh of relief and led him into the second cave.

Seeing the pile of spiritual stones on the ground, Lu Chen fell into a sluggish state again, his eyes filled with excitement.

A rough estimate is that there are at least 100,000 spiritual stones in this cave alone.

Probably because it was eroded and burned by lava, the shape of the spirit stone in front of him was not as regular as the ones Lu Chen had obtained before, and the surface contained more cracks and impurities.

It looks bumpy, bumpy, and not round at all.

However, the bursts of energy fluctuations emitted inside all show that their identities are indeed spiritual stones.

First-grade, second-grade, third-grade... there are even suspected fifth-grade spiritual stones.

I have to admit that Lu Chen was completely tempted.

For a moment, the previous thought emerged again.

Should we kill all these guys and monopolize the treasure house of spiritual stones?

For a moment, he regained his senses.

Can't kill!

It's not that Lu Chen is too soft-hearted to take action. These guys are just alien ferocious beasts, not Blue Star humans. Even if they are exterminated, it won't be a big deal.

The key is to take a long-term view. Rather than fishing for the best, he is more willing to keep the water flowing.

Before entering the dragon's lair, Lu Chen had already thought about how to use the lizard tribe.

These guys are born with special physiques that can withstand high temperatures and pressures, and can go deep into the veins inside volcanic lava to find spiritual stones. It is for this reason that the alien dog-headed monks keep them here.

As long as you make good friends with them, you can get spiritual stones continuously.

And wiping out the entire lizard clan would indeed yield a lot in a short period of time, but it would become a one-time deal and it would be difficult to obtain new spiritual stones in the future.

So far, Lu Chen didn't know whether he could go deep into the bottom of magma to find spiritual stones like the lizard tribe.

If possible, genocide should be considered.

Your Majesty, according to our previous agreement, you can take 50,000 spirit stones as my ransom. At this time, the Lizard King said again.

Can I take all the spiritual stones?

Lu Chen suddenly remembered that during the previous negotiation, the two parties only agreed on the quantity and did not confirm the grade of the spirit stones.

My side defaults to the first-grade spiritual stone... but judging from the Lizard King's nonchalant look, it's obvious that any number of grades will suffice.

In this way, the operating space is large.

Of course, as long as your Majesty doesn't touch my gold, you can choose all the spiritual stones. Seraphim nodded again.

Lu Chen would naturally not be polite after being recognized by the other party.

He dodged and came closer, took the lead in grabbing the fifth-grade spiritual stone, and then took the third-grade and second-grade spiritual stone and pulled it all at once.

After all the high-quality spiritual stones have been selected, we can start to get the first-grade ones.

Even so, Lu Chen felt like he was spoiled for choice.

He was even thinking about how to make all the spiritual stones in front of him his own.

Exchange for gold? ? !

Judging from the appearance of the Lizard King, it is obvious that he values ​​gold more.

You can exchange gold with the other party and travel through two dimensions to become a villain.

According to Blue Star's human calculations, a first-grade spiritual stone can be sold for a high price of millions, and can be exchanged for four or five pounds of gold.

So as long as you do a one-to-one exchange, it will be several times the profit.

However, it is a waste of time to go back and forth between the two dimensions, and it is not safe to do business with humans. It is easy to be cheated if you are not careful.

Lu Chen suddenly remembered that a leader of the crocodile tribe had once presented a gold nugget to him as a treasure, indicating that there were also gold mines in the crocodile tribe's territory.

You can try to mine and extract gold for trading.

Wait...it seems there is a cheaper one.

In addition to the bright yellow gold, the Lizard King's treasure house also contains many high-purity gemstones of various colors, most of which are ground into spherical shapes.

Seeing those gems, Lu Chen immediately thought of a great invention in the human world - artificial crystal.

This thing is absolutely shiny after polishing, crystal clear, and looks high-end and classy.

In fact...artificial crystal is glass containing lead oxide.

The higher the lead oxide content, the higher the refractive index and hardness, and the more pure and crystal clear the finished product will be.

Just now in the Lizard King's treasure house, Lu Chen didn't see any glass products, which meant that these guys didn't get the glass-making technology from the alien kobolds.

Judging from the current level of development of the lizard civilization, they certainly have not invented relevant technology.

The materials and methods for making glass are very simple. You just add something to the sand and heat it to a certain temperature to melt it.

But if you don't understand its production process, it may take thousands of years to study it.

As far as Lu Chen knew, in the previous life, for a long time after the invention of glass, the production method was classified as a secret.

There is even a country that deliberately set up a glass factory on an isolated island in order to prevent craftsmen from leaking secrets.

Later, you can try to customize some high-purity crystal glass and colorful glass balls from Dong Mingjun, preferably larger.

Then show it to the lizard tribe to see if they are interested.

If this method works, you will definitely make a lot of money.

It's a completely independent business, with no one competing with you at all.

After coming out of the Lizard Palace, Lu Chen tentatively asked if he could go near the volcanic lava to have a look.

I originally thought that the Lizard King would shirk, but I didn't expect that this guy would agree without hesitation.

Under the leadership of the other party, Lu Chen passed through a tall, spacious and dark cave passage, and finally entered the belly of the mountain. After running for four or five miles, a rolling heat wave suddenly hit the front, mixed with a strong and pungent smell of sulfur.

Feeling that his nostrils were filled with volcanic ash, he quickly held his breath.

With Lu Chen's current state, it would be no problem not to breathe for more than ten hours.

A few dozen meters away, a huge volcanic lava lake appeared in front, covering an area of ​​100,000 square meters.

The bright red magma flows slowly, and under the huge pressure from the ground, flames continue to erupt into the sky, emitting billowing black smoke, like a giant dragon rising into the sky.

Among them, traces of spiritual energy energy fluctuations are constantly coming out.

Standing next to the lava lake, Lu Chen felt his body temperature rise sharply.

Among the volcanic lavas of Blue Star, basic basalt magma has the highest temperature, reaching 1000-1300°C. The acidic rhyolite magma has a lower temperature, about 700-900°C.

However, this data is a temperature measured by humans under normal pressure on the surface. Due to volatilization and heat loss, it cannot fully represent the true temperature of magma deep underground.

With Lu Chen's current body, he could withstand high temperatures for a short period of time, but at most a few hundred degrees had reached its limit.

As for the high temperature of thousands of degrees, he has never tried it.
