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

Eve and the beef ball began to have a "friendly" discussion based on the plasma insect fossil.

Han Youwei leaned next to Fang Yuan and thought about her thoughts: "The Plasma Worm faces one place uniformly and should be fleeing in the same direction. But in the end it was buried in the ground and became a fossil. I thought of a kind of may....

"Do you think it might be magma? The magma gushes out from the ground, flows through the cave, and drowns the plasma insects in the magma, and finally all becomes fossils."

Fang Yuan nodded and said: "I also thought of this possibility, but it's still uncertain for the time being. The situation here is different from the situation after the magma has cooled. No volcanic ash was seen."

"Maybe the magma contains too high a silica content, forming silica crystals." Han Youwei recalled the chemical properties of silica.

Although the crystals on the side of the star beast world are usually referred to as crystals, there are more than one type of silica crystals. In addition to crystals, there are several types of crystals such as agate.

These crystals can be collectively referred to as silica crystals.

"I remember that to form silica crystals, water is needed." Fang Yuan has focused on star power cultivation for the past year, but he has not returned all the knowledge he has learned to his teacher.

"Well, there is actually an environment for the formation of silicon dioxide crystals, high temperature, high pressure, and high purity silicon dioxide. The only thing missing is water. Maybe water has washed away here. After the crystal layer is formed, the water is caused by crustal movement. It dries up slowly." Han Youwei said thoughtfully.

"There is indeed such a possibility. For the specific situation, we still have to take the sample back and hand it over to the Academy of Military Sciences for research." Fang Yuan knocked on a few silica crystals and threw them to Eve’s MEKA mecha. In the sample box.

After collecting the samples.

Fang Yuan used the advanced authority of the talker, turned on the broadcast function, and reminded: "Go ahead, it is very likely that you will encounter magma, everyone should be vigilant."

Zhao Anya answered, "Do you think these plasma insect fossils were formed after being swallowed by magma?"

"Yes, we all think this should be the case." Fang Yuan affirmed.

The beef ball frowned and asked, "Is it swallowed by magma, isn't it burning to ashes?"

"I want to burn plasma worms to ashes at a thousand degrees? Do you look down on plasma more?" Eve vomited.

"Continue to explore and see."

Fang Yuan took the lead as he spoke.

The further the team went, the more star beast fossils they saw.

Not only was the Crystalline Plasma Worm, but even saw spine predators.

"I have seen this spine-spine predator. There are fossils of this spine-spine predator in the Military Academy. It is an ancient predator 2.5 million years ago." Eve saw an ancient predator. After the fossil of the writer, he suddenly became excited.

"2.5 million years? You mean, there were star beasts 2.5 million years ago? Is this possible?" The beef **** scratched their heads, feeling incredible.

"What's impossible? The era when the earth's dinosaurs ruled the land is between 250 million and 6,500 years ago. There is a fossil beast 2.5 million years ago, and the time is not even a fraction of the Cretaceous." Eve said.

"The star beast has evolved for 2.5 million years, why is it still so weak? If humans have evolved for 2.5 million years, it would be terrifying?" Beef Ball suddenly began to diverge.

"In fact, it is not necessarily true. Human civilization appeared 5,000 years ago, but the technological explosion was only 200 years old. 200 years ago, humans did not even have electricity. The leap of civilization depends on the technological explosion. Not as much progress as the modern 50 years." Fang Yuan said.

"The development route of the Star Beast civilization is different from ours. The Star Beast civilization is not a technological route. It is not surprising that there has been no major progress in 2.5 million years. Dinosaurs have ruled the earth for almost 200 million years and have not developed into a higher civilization." Han Youwei did. Let me add.

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

"Hey... if there are plasma worm eggs, then it should be certain that this place was once very suitable for plasma worm life. If there are only adult plasma worms, it can also be said that for some reason, plasma worms were driven here. But if there are plasma worm eggs, it means that plasma worms once laid their eggs here, and this must be an environment suitable for plasma worms to live." Fang Yuan took the plasma worm eggs and observed them carefully.

"If this is the case, 2.5 million years ago, the temperature here should be around zero, not more than 50 degrees." Zhao Anya made a judgment.

The group continued to move forward.

The farther you go, the more surprising you see.

The space of the cave is getting bigger and bigger.

"You can't be wrong. It must have been an area with dense star beasts. This is clearly the Plasma Worm Nest."

Moving on, I saw a bigger nest again.

I also saw a fossil of a thunder monster, which was processed in the lair.

Thunder behemoth is a very powerful kind of star beast. It is more than ten meters tall and looks a bit like a mammoth, but it is stronger and more ferocious. Its teeth are like two machetes, which can cut prey into pieces.

Next.

The group saw the fossils of the fissure Hydralisk again, and they were clusters of Hydralisk fossils.

Fang Yuan couldn't help swallowing when he saw the clusters of Hydralisk fossils.

The Rift Hydralisk is a very dangerous star beast. The adult Rift Hydralisk has war-level combat effectiveness.

If you encounter a group of live Hydralisks, the result is really hard to tell.

After entering the territory of the Thunder Behemoth, the exit on the side of the earth has exceeded 50 kilometers.

The temperature is getting higher and higher.

The MEKA mecha began to beep.

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

"Can you stand it? I heard the high temperature alarm." Fang Yuan asked.

"This is a yellow alarm. It hasn't been able to withstand it, but it's already a bit dangerous." Eve replied.

Everyone in the team is under great pressure.

Du Jun greeted: "They are all concentrated near the mecha, and the ice-type abilities cooperate to control the temperature."

Among the twelve-member team, four have the ability to control temperature, two of the ice element, and one of heat absorption.

Fang Yuan turned around and said, "Eve, you can feed little Sunflower some spirit stones and let it cool down."

Eve opened a box of biscuits, broke one off, and said, "Little Sunflower, help cool down."

"I'm afraid you can't stand the cold." The little sunflower parrot began to communicate.

"Speaking is getting stronger and stronger, don't freeze, you can withstand it." Eve broke another biscuit and handed it over.

Suddenly, a cold wind blew around the mecha, and the temperature began to drop, alleviating the pressure on everyone.
