Evolution from the crocodile

There are also several murals with dots of stars connected by dotted lines, which seem to be star maps.

However, Lu Chen looked carefully for a long time and couldn't see anything.

He simply stopped caring about the murals and turned his attention to the huge sarcophagus in the center of the tower.

According to the universal theorem, whether humans or alien creatures, they will place funerary objects in tombs.

I hope this can bring me some surprises.

But when Lu Chen came closer, he felt an inexplicable sense of crisis in his heart. It seems dangerous inside.

Immediately, he summoned swamp black mud from the inner space, covering the surface of his body with a layer of mud armor.

Then he condensed two broad toe claws and opened the top of the sarcophagus.

swish swish...

A few seconds later, there was a sudden noise in the sarcophagus, as if something was awakening.

Click click click...

A black beetle as big as a fist suddenly crawled out from inside.

These guys stretched their wings and suddenly flew quickly towards Lu Chen in a group. After landing on the mud armor, he opened his sharp and hard upper jaws and gnawed at it frantically, making holes one after another in the blink of an eye.

Damn... Fortunately, I was prepared!

The swamp black mud covering the body surface once again spread into black mist, quickly enveloping the strange beetles in it, and then exploded...

After feeling that they were all blown up, Lu Chen breathed a sigh of relief.

These beetles have a hard body and fly extremely fast. In a confined space, it is really easy to get hit if you are not careful.

Sensing that there were indeed no beetles in the sarcophagus, Lu Chen moved closer to observe.

There are no remains of alien creatures inside the sarcophagus, only a honeycomb-shaped object.

If nothing else, this should be the nest of those beetles.

They were sealed by the runes carved on the sarcophagus and should have been sleeping. After they opened the top of the sarcophagus, they woke up from their slumber and attacked the living creatures in the tomb.

Therefore, this is an anti-theft method used by alien creatures. According to the records in the Sixteen-Character Yin-Yang Feng Shui Secret Technique from the previous life, there must be real coffins here.

However, Lu Chen looked at the entire space and found no other secret passages.

With doubts, he carefully observed the paintings on the stone wall again.

After checking it for a week, something felt wrong.

He is now 16 meters long. From one end to the other, he is almost five feet long, which is about 80 meters.

Lu Chen suddenly woke up and finally understood where this strangeness came from.

In order to verify his idea, Lu Chen went outside the pyramid again and carefully measured the length of one side of the tower base.

This pyramid is the shortest of all the pyramids. The outside length is less than 70 meters, but the inside of the tower is 80 meters... This is not scientific at all.

So there may be a structure similar to inner space inside?

Lu Chen felt that he had guessed the truth, and was bombarded by another wave of compressed energy bombs.

Sure enough, countless runes flashed on the stone walls inside the tower, forming a transparent light shield to block the attack.

He didn't need to take any deliberate aim at all and continued to bombard randomly.

Lu Chen firmly believed that magical powers were no match for the powers of heaven.

No matter how powerful the defensive runic array is, it cannot withstand the erosion of time.

It can also be seen from the thick vines outside the tower that these pyramids have existed for at least a thousand years.

There is probably not much energy left inside to maintain the defensive array. Otherwise, he would not be able to easily break through the outer protective shield.

Sure enough, after a dozen attacks were launched in succession, the transparent mask shattered. The true structure inside the pyramid was completely revealed in front of Lu Chen.

The inside is not made of stones, but made of bronze metal. It is engraved with dense runes and shines brightly.

Especially the goose egg-sized ball at the top is as bright as a small sun.

Spiritual stone? !

Those stone buildings are indeed just a cover-up.

The real internal structure is a bronze fortress with a side length of hundreds of meters and a height of tens of meters, with many mysterious and mysterious runes engraved on it.

Although it has gone through countless years, the entire interior shows no trace of decay. Embellished by countless spiritual stones, it still exudes a cold metallic luster.

In the center of the pyramid, there are rows of bronze coffins. The shape is similar to the sarcophagus he destroyed before, and the surface is also engraved with countless runes.

Seeing the spirit stone, Lu Chen's beast eyes shone with joy. Being in it, he felt the rich energy aura, as if his whole body was bathing in the hot spring, feeling comfortable and comfortable.

There are hundreds of these...

Especially the goose egg-sized one at the top of the pyramid, which is at least third grade!

Developed, really developed this time!

Without any hesitation, Lu Chen immediately summoned the swamp black mud and flew to the top. A huge dark clay hand grabbed the spirit stone directly from the bronze ceiling.

Click, click...

Almost as soon as the spirit stone came out of the groove, there was a sound inside the pyramid fortress, and something was broken.

As early as when he grabbed the spirit stone, Lu Chen was highly concentrated.

Hearing the unusual noise, he immediately controlled the dirt platform to fall rapidly, making a warning gesture.

He fell back to the ground and waited for half a minute. When no creature appeared, Lu Chen breathed a sigh of relief.

Then, he noticed that the newly shiny bronze fortress began to rust. It seems that in just a few dozen seconds, a hundred years of vicissitudes have gone through.

This...may be related to the spirit stone in his hand.

It is these spiritual stones that maintain the operation of the rune array in the bronze fortress. Once the structure is destroyed, it will naturally be unable to withstand the erosion of time.

However, Lu Chen had nothing to be embarrassed about.

Even if the pyramid in another space is a cultural relic, it is still an alien cultural relic and has nothing to do with me.

With curiosity and greed, he looked again and again at the goose egg-sized ball in his toe claws.

When you are close at hand, you can feel the majestic energy contained in it, which is far beyond any spiritual stone obtained before.

After confirming that there was no problem, Lu Chen couldn't wait to open his mouth and swallow it.

The broken fifth-grade spiritual stone can provide 920,000 energy points...

How many?

Fifth-grade spiritual stone, 920,000 energy points?

Lu Chen was surprised at first, and then a little regretful.

A fifth-grade spiritual stone is probably the only one in Blue Star.

From previous conversations with Dong Mingjun, Lu Chen learned that the highest grade of spirit stones currently mined in Xia was only the third grade. The one he had just swallowed had already reached the fifth grade, which was beyond imagination.

However, the energy points it contains are somewhat disappointing.

After devouring so many spiritual stones, Lu Chen also had a general understanding of the energy points contained in each grade. For each additional level, the energy points increase tenfold.

The first level is about 400 energy points, and the second level is 4000 points. By analogy, the fifth-grade spiritual stone should be about 4 million points. Unfortunately, the one I got was incomplete and provided less than one million energy points.

However... there are many spiritual stones inside the fortress. Although the grade is not as good as the one in front of me, they should still be able to provide a lot of energy points.

In addition, there are dozens of pyramids in the mausoleum area.
