Chapter 213: A Small Group of Xingyuan Mines (Guarantee One)

"The gravity is 13g, which is smaller than the last space crack." Fang Yuan felt the change in gravity and reported the approximate value of gravity.

"I just said why the shield feels so much heavier, but why is the gravity so different?" Niu Dazhi scratched his head, wondering why.

Han Youwei helped solve the puzzle: "On the surface of the planet, the closer it is to the center of the earth, the greater the gravity; however, inside the planet's crust, the closer it is to the center of the earth, the lower the gravity. That is to say, the position we enter this time is closer. The center of the star world."

The five people in the team continued to move forward, and all they saw along the way were the strange aquamarine caves.

The beef balls picked crystals along the way and said, "I didn't have time to bring these gems back last time. This time I must bring a few pieces back, they must be very valuable."

"It's worth a fortune, ten dollars a piece." Eve rolled her eyes.

"No, how can it be so cheap? This is something in the space rift, how many people dare to come and get it?" Beef Balls didn't believe it.

"Silica, how expensive do you think it is?" Eve continued to roll her eyes.

"What is silica? It sounds familiar." Beef Balls asked.

"It was taught by the junior high school chemistry and physical education teacher." Eve laughed wildly and enjoyed running on beef balls all day.

"Fang Yuan, what exactly is silica?" The beef balls were a little angry, and turned to ask Fang Yuan.

"I really convinced you, how did you get into the first middle school?"

Fang Yuan was a little speechless, but he still answered his question: "It's just a crystal, it's really worthless. Picking up a piece and going back, it can probably be exchanged for a bowl of beef noodles... right?"

Hearing that the beef balls were crystals, he immediately threw away the crystals in his hand: "No, there are bargains all over the world!"

He turned his attention away from the crystal and asked again, "Why is there so much silicon dioxide in the star beast world? And there's no oxygen, so the star beast doesn't need to breathe?"

"A quasar and you are not the same thing, of course you carbon-based life will not understand." Eve began to tease him again.

The beef balls said with a stern face: "Can you say something that people can understand? What is carbon-based life?"

"I have many secrets, I won't tell you, I won't tell you..." Eve sang.

The beef balls looked suffocated.

Seeing that they were about to fight, Han Youwei said, "Eve, don't yell at him. Tell him the answer."

"You said, I don't want to explain this kind of common sense problem." Eve pouted.

Han Youwei had to explain: "Okay. Carbon-based life is a creature based on carbon element. We humans are carbon-based life, and the body's protein and other substances are all based on carbon element, combined with nitrogen, hydrogen and oxygen. ...

"The star beast is different. The star beast world has a lot of silicon elements, and the creatures that lead to the star beast world are all silicon-based life forms.

"And carbon and silicon are adjacent to each other on the periodic table, and their chemical properties are relatively similar. If we replace all carbon in our human proteins with silicon, then we will become silicon-based life."

Having said this, Han Youwei paused, and then added: "However, only the a-type star beasts are silicon-based life forms, and the b-type star beasts have absorbed some of the genes of earth creatures, and some of them are carbon-based."

After listening to the beef balls, he suddenly realized: "I understand it if you say this, that is, the chemical elements of the star beast's body are different from ours."

Eve covered her forehead and commented: "It's a fool's understanding, and she understands it very clearly."

"Captain, we have to pay attention to the time. We must go back before the oxygen tank runs out. And after coming in for so long, we haven't seen the star beast, nor the body of the star beast. Will we be going in the wrong direction?" Ye Zhe Yu reminded.

Fang Yuan looked at the time and said, "Come in for about 30 minutes, explore for another 30 minutes, then turn around."

The team of five continued to move forward.

After a few minutes, Fang Yuan stopped and looked up at the surroundings.

"What's wrong?"

"We seem to have returned to the starting point. This place seems to have been passed before." Fang Yuan is not very sure, because the crystal caves look very similar.

"Every place here looks the same, are you sure?" Beef Balls didn't remember passing this place just now, or that he felt the same everywhere he went.

Eve swiped with the tablet and said, "We are indeed turning in circles. The road we just walked is turning to the right as a whole, and it is indeed possible to return to the original point."

Han Youwei walked over to a crystal cluster to check, and said, "There is indeed a mark, we walked here before."

Eve began to calculate and draw on the tablet, and soon came to the conclusion: "According to our moving speed, we are probably going around a circle with a circumference of 8 kilometers. It is probably the bottomless abyss on our right hand side. ."

She said and pointed to the bottomless abyss on her right.

The cave where the five members of the team are now is very special.

The entire cave is a circle with a circumference of eight kilometers, the left side is the cave wall, and the right side is a bottomless abyss.

Explore the bottomless abyss with the eye of the ghost, and you can't see the bottom at all.

However, you can see the edge of the bottomless abyss, and there are circles of exposed caves, like rings, set on the bottomless abyss.

The cave where the five members of the team are located is one of the circles.

"Would you like to take a look at the caves on the next floor?" Fang Yuan asked everyone for their opinions.

"In case of falling into the bottomless abyss, there is no way to save it." Ye Zheyu was more cautious.

"It's all in, but I didn't find anything. It's boring to go back like this. I'll support it and see." Eve raised her hand to express her opinion.

After the five people discussed, they finally decided to continue to explore the cave on the next floor.

So, Fang Yuan made an iron chain, tied it to a crystal cluster, and put it down the bottomless abyss.

The five people fastened the buckles of the combat uniforms on the iron chains and slid down the chains.

After descending fifteen meters, he entered the cave on the next floor.

The team of five continued to explore.

Finally found a star beast lair.

These star beasts are only level 6 and 7, so Fang Yuan decisively launched an attack to destroy the star beast lair.

Eve found a small amount of light blue powder in the star beast's lair, carefully packed it in a small glass bottle, her face full of excited expressions.

The beef balls moved up, wanting to see what she was doing.

"Go away, one milligram less will kill you." Eve threatened.

"what is this?"

"Xingyuan Mine."

The five people gathered around, looking at the light blue crystal powder the size of the thumb cap in the glass bottle, wondering: "This is Xingyuan Mine?"

"Shouldn't the ore be chunks?" The beef balls scratched their heads.

"This is the Xingyuan Mine, which was collected by the rift star beast. It's just that, it's worth the price." Eve explained.
