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

Eve and Beef Balls began to have a "friendly" discussion based on the matter of plasmaworm fossils.

Han Youwei leaned against Fang Yuan and thought about what she thought: "The plasmaworms faced one place in one direction, and should be running in the same direction. But in the end they were buried underground and became fossils. I thought of a possibility...

"Do you think it's possible that it's magma? The magma surges out from the ground, flows through the cave, submerges plasmaworms in the magma, and eventually becomes 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 different from the situation after the magma cools down, and no volcanic ash is seen."

"Maybe it was because the magma had too high silica content, which formed silica crystals." Han Youwei recalled the chemical properties of silica.

Although the crystals on the Star Beast World are usually called crystals, there is more than one silicon dioxide crystal. In addition to crystals, there are several crystals such as agate.

These crystals can all be collectively called silicon dioxide crystals.

"I remember that to form silicon dioxide crystals, water is required." Fang Yuan has been practicing star power in the past year, but he has not returned all the knowledge he has learned to the teacher.

"Well, there is actually an environment where silicon dioxide crystals are formed here, high temperature, high air pressure, and high purity silica. One of the missing ones is water. Perhaps water has been washed here, and after forming the crystal layer, the water slowly dried up due to the movement of the earth's crust." Han Youwei said thinking.

"There is indeed a possibility. In the specific situation, we still have to take the sample back and leave it to the Academy of Military Sciences for research." Fang Yuan said and knocked on a few pieces of silicon dioxide crystals, threw it to Eve's meka mecha, and placed it in the sample box.

After collecting the samples.

Fang Yuan used the advanced permissions of the caller to turn on the broadcast function and reminded: "Continue to move forward, you may encounter magma, so everyone should be vigilant."

Zhao Anya responded: "Do you think these plasmaworm fossils were formed after being swallowed by magma?"

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

Beef ball frowned and asked, "Will it be burned to ashes by being swallowed by magma?"

"I just want to burn plasmaworms to ashes for one thousand degrees? How much do you look down on plasma?" Eve complained.

"Continue to explore and see."

Fang Yuan said and took the lead in walking forward.

The more the team moved forward, the more star beast fossils they saw.

Not only were the crystal-armed plasmaworms, but they even saw the spine-bone predator.

"I have seen this kind of ridge hunter hunter. There are fossils of this kind of ridge hunter hunter in the Academy of Military Sciences. They are ancient hunters two million and five million years ago." Eve was immediately excited after seeing the fossil of an ancient hunter.

"Two.5 million years? What do you mean is that there were star beasts two million and five million years ago? Is this possible?" Beef balls scratched their heads, and it felt incredible.

"What's impossible? The era when dinosaurs on Earth ruled the land dated 250 million to 6500 years ago. A fossil of a star beast from 2.5 million years ago appeared, and it was not even a fraction of the Cretaceous period." 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, how terrifying would it be?" Beef balls immediately began to diverge their thinking.

"In fact, it is not necessarily true that human civilization appeared 5,000 years ago, but the technological explosion only lasted 200 years. 200 years ago, humans did not even have electricity. The leap of civilization still depends on the technological explosion. The progress in the past 5,000 years is not as great as the progress in modern times in 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, and it is not surprising that there has been no great progress in 2.5 million years. Dinosaurs have ruled the earth for about 200 million years, and they have not yet developed into a higher civilization." Han Youwei added.

After saying that, she ran a few steps, ran to the corner of the cave, picked up a crystal fossil, held it in front of everyone, and said, "Look at it, plasmaworm eggs."

"Huh... If there are plasmaworm eggs, then it should be certain that this place was once very suitable for plasmaworm life. If there are only adult plasmaworms, it can be said that the plasmaworm was driven here for some reason. But if there are plasmaworm eggs, it means that the plasmaworm once lay eggs here, and this place is definitely a suitable environment for plasmaworm survival." Fang Yuan took the fossil of the plasmaworm egg and observed carefully.

"If this is the case, 2.5 million years ago, the temperature here should be around zero degrees, and the upper and lower levels will not exceed 50 degrees." Zhao Anya made a judgment.

The group continued to move forward.

The more you go, the more surprising you see.

The space in the cave is getting bigger and bigger.

"It's definitely not wrong. This was a dense area of ​​star beasts before, and this one was clearly a plasmaworm nest."

Keep walking forward and see a larger nest again.

I also saw a fossil of a thunder beast, which was processed in the nest.

The Thunder Giant Beast is a very powerful star beast. It is more than ten meters tall and looks a bit like a mammoth, but it is stronger and more hideous. The teeth are like two scimitars that can cut prey into pieces.

Next.

The group saw the fossils of the fissure sting snakes again, and the groups of sting snakes.

Fang Yuan couldn't help swallowing when he saw the fossils of prickly snakes.

The cleft stinger is a very dangerous star beast. The adult cleft stinger has war-level combat power.

If you encounter a group of living thorn snakes, the result is really hard to say.

After entering the territory of Thunder Behemoth, the exit from the Earth side has exceeded 50 kilometers.

The temperature is getting higher and higher.

The meka mecha started to beep the alarm.

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

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

"This is a yellow alarm. It's not time to hold on, but it's already a little dangerous." Eve replied.

Everyone in the team is under great pressure.

Du Jun called out: "Everyone is concentrated near the mecha, and the ice-type superpowers cooperate to control the temperature."

Among the twelve teams, four have supernatural powers that control temperature, two ice systems and one heat absorption.

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

Eve opened a box of cookies, broke them down, and tempted, "Little Sunflower, help cool down."

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

"You're talking more and more powerfully. Don't freeze, you can resist it." Eve broke up another biscuit and handed it over.

Suddenly, a cold wind blew around the mecha, and the temperature began to drop, eased the pressure on everyone.
Chapter completed!
