"Who told you that fossils are formed by petrification?"

Eve and Beef Maru begin to have a "friendly" discussion about the fossil plasma worm.

Han Youwei leaned over to Fang Yuan's side, thinking about it and saying her thoughts: "The plasma worms are facing the same place, they should be fleeing in the same direction. But in the end, it was buried in the ground and became a fossil, and I thought of a possibility......

"Do you think it's possible magma? Magma gushes out of the ground and flows through the caverns, drowning the plasma worms in the magma and eventually turning them all into fossils. ”

Fang Yuan nodded and said, "I also thought of this possibility, but I am not sure for the time being, the situation here is not the same as the situation after the magma cooled, and I didn't see the volcanic ash." ”

"Maybe the magma has too much silica and silica crystals have formed." Han Youwei recalled the chemical properties of silica.

Although it is common to say that the crystals on one side of the Star Beast World are crystals, there is more than one type of silica crystal, and in addition to crystals, there are several crystals such as agate.

These crystals can be collectively referred to as silica crystals.

"I remember that to form silica crystals, you need water." In the past year, Fang Yuan has mainly focused on star power cultivation, but he has not returned all the knowledge he has learned to the teacher.

"Well, there is actually an environment for the formation of silica crystals here, high temperature, high air pressure, high purity silica, and what is missing is water. Perhaps there was water washed over here, and after forming a crystalline layer, the water slowly dried up due to the movement of the earth's crust. Han Youwei said thoughtfully.

"There is indeed such a possibility, and in the specific case, it is still necessary to bring the samples back and hand them over to the Academy of Military Sciences for study." As he spoke, Fang Yuan knocked on a few silica crystals, threw them to Eve's Meka mecha, and put them in the sample box.

After the sample is collected.

Fang Yuan used the advanced permission of the intercom to turn on the broadcast function and reminded: "Continue forward, it is likely to encounter magma, everyone be vigilant." ”

Zhao Anya answered: "Do you think these plasma worm fossils were formed after being swallowed by magma?" ”

"yes, we all think that's the case." Fang Yuan affirmed.

Beef Maru frowned and asked, "Swallowed by magma, isn't that burned to ashes?" ”

"A thousand degrees want to burn the plasma worm to ashes? How much do you look down on plasma? Eve complained.

"Keep exploring."

Fang Yuan said and took the lead to walk forward.

The further the team went, the more Star Beast fossils they saw.

Not only crystal beetle plasma worms, but even stingy predators.

"I have seen this kind of spiny predator, and there are fossils of this kind of spiny predator in the Academy of Military Sciences, which is an ancient predator from two and a half million years ago." Eve was excited when she saw the fossil of an ancient predator.

"Two and a half million years? You mean to say that there were star beasts 2.5 million years ago? Is this possible? "Beef balls scratch their heads, it feels incredible.

"What's impossible? Earth's dinosaurs ruled the land from 250 million to 6,500 years ago. The appearance of a 2.5 million-year-old star beast fossil is not enough for even a fraction of the Cretaceous period. Eve said.

"Star beasts have evolved for 2.5 million years, why are they still so weak? How terrifying would it be if humans had evolved for 2.5 million years? Beef balls suddenly began to diverge their thinking.

"Actually, it is not necessarily, human civilization appeared 5,000 years ago, but the Big Bang of science and technology was only 200 years old, and 200 years ago, human beings did not even have electricity. The leap of civilization still depends on the big bang of science and technology, and the progress of the past 5,000 years is not as great as the progress of modern times in the past 50 years. Fang Yuan said.

"The development route of the Star Beast Civilization is different from ours, the Star Beast Civilization is not a scientific and technological route, and it is not surprising that there has been no great progress in 2.5 million years. Dinosaurs ruled the earth for almost 200 million years, and they did not develop into advanced civilizations. Han Youwei made a supplement.

After she finished speaking, she ran a few steps, ran to the corner of the cave, picked up a crystal fossil, held it up in front of everyone, and said, "Look, plasma worm eggs. ”

"Huh...... If there are plasma worm eggs, then it should be certain that this place was once very suitable for plasma worms. If there are only adult plasma worms, it can also be said that for some reason, plasma worms are driven here. But if there are plasma worm eggs, it means that plasma worms once laid eggs here, and this must be a suitable environment for plasma worms to live. Fang Yuan took the fossil of the plasma insect egg and looked at it carefully.

"If that were the case, 2.5 million years ago, the temperature here would have been around zero degrees, and it wouldn't have been more than 50 degrees up or down." Zhao Anya made a judgment.

The group continued to walk forward.

The further you go, the more surprising you see.

The space of the cave is also getting larger.

"You can't be wrong, this must have been an area with a dense concentration of star beasts before, and this is clearly a plasma worm nest."

As I walked on, I saw an even larger nest.

I also saw the fossil of a thunder beast, which was disposed of in the lair.

The Thunder Behemoth is a very powerful of the Star Beasts, more than ten meters tall, a bit like a mammoth in appearance, but stronger and more hideous, with teeth like two scimitars that can cut their prey into pieces.

Next.

The group saw the fossils of the Rift Stinging Snake again, and it was a group of stinging snake fossils.

Fang Yuan couldn't help but swallow when he saw the swarm of stinging snake fossils.

The Rift Stinger Snake is a very dangerous star beast, and the adult Rift Stinger Snake has war-level combat power.

If you encounter a swarm of live stinging snakes, the result is really hard to say.

After entering the Thunder Behemoth Territory, it was already more than 50 kilometers away from the exit on the Earth side.

The temperature is also getting hotter.

The Meka mech began to beep the alarm.

"It's 500 degrees, it's over 500 degrees." Eve reminded aloud.

"Can you still withstand it? I heard a heat alarm. Fang Yuan asked.

"It's a yellow alert, it's not too much to stand it up, but it's already a bit dangerous." Eve replied.

There was a lot of pressure on everyone in the team.

Du Jun greeted, "All gather near the mecha, and the ice ability will cooperate to control the temperature." ”

Of the twelve, four have temperature-controlling abilities, two ice-based, and one heat-absorbing.

Fang Yuan turned around and said, "Eve, you feed the little sunflower some spirit stones and let it help cool down." ”

Eve opened a box of biscuits, broke a piece of it, and seduced, "Little Sunflower, help cool down." ”

"I'm afraid you're too cold to stand it." The little sunflower parrot began to communicate.

"I'm talking more and more, don't freeze, you can withstand it." Eve broke another cookie and handed it over.

Suddenly, a cold wind blew around the mecha, and the temperature began to drop, relieving everyone's pressure.
