"I just said how I feel that the shield is heavier, but why is the gravity so much worse?" Niu Dazhi scratched his head, wondering why.
Han Youwei helped to clarify: "On the surface of the planet, the closer to the center of the earth, the greater the gravity; but inside the crust of the planet, the closer to the center of the earth, the lower the gravity. In other words, the position we entered this time is closer The center of the earth in the star beast world."
The five members of the team continued to move forward, and all they saw along the way were the strange Kyanite caves.
The beef picked the crystals along the way, and said: "I didn't have time to take these gems back last time. This time I must take a few pieces back. It must be very valuable."
"Very worthy ghost, ten dollars a dollar." Eve rolled his eyes.
"No, how could it be so cheap? This is something in a rift in space, how many people dare to come over and get it?" The beef didn't believe it.
"Silica, how expensive do you think it can be?" Eve continued to roll his eyes.
"What is silica? It sounds familiar." The beef ball pressed.
"Teached by the junior high school chemistry and physical education teacher." Eve laughed presumptuously, squeezing beef all day.
"Fang Yuan, what exactly is silicon dioxide?" The beef ball was a little angry and turned to ask Fang Yuan.
"I really convinced you, how did you get into the first high school?"
Fang Yuan was a little speechless, but still answered his question: "It's a crystal, it's really worthless. Picking up a piece and going back, maybe you can get a bowl of beef noodle... right?"
As soon as the beef heard that they were crystals, they immediately threw them away: "No more, bargains all over the world!"
He moved his attention away from the crystal and asked, "Why is there so much silica in the star beast world? And there is no oxygen. Does the star beast need not breathe?"
"Class A star beasts are not the same thing as you. Of course you, a carbon-based life, don't understand." Eve began to tease him again.
The beef sternly said, "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 looked bored.
Han Youwei saw that they were about to fight, and said: "Eve, don't bully him. Tell him the answer."
"You said, I don't want to explain this kind of common sense problem." Eve curled his lips.
Han Youwei had no choice but to explain: "Okay. Carbon-based life is an organism based on carbon. We humans are carbon-based life. The proteins and other substances in the body are based on carbon and are composed of nitrogen, hydrogen, and oxygen. ...
"The star beasts are different. There are many silicon elements in the star beast world. The creatures that lead to the emergence of the star beast are silicon-based life.
"Furthermore, carbon and silicon are adjacent to each other on the periodic table, and their chemical properties are relatively similar. If we replace all the carbon in our body protein with silicon, then we will become silicon-based life."
Having said this, Han Youwei paused, and then added: "However, only Class A star beasts are silicon-based life, and Class B star beasts have absorbed some of the genes of earth creatures, and all of them are carbon-based."
After listening to the beef balls, it suddenly dawned on him: "I understand it this way. The chemical elements in the body of the star beast are different from ours."
Eve covered his forehead and commented: "It's a fool to understand, and it's quite thorough."
"Captain, we must pay attention to the time. We must go back before the oxygen tank is used up. Moreover, after coming in for so long, we haven't seen the star beast nor the star beast corpse. Will we go in the wrong direction?" Ye Zhe Yu reminded.
Fang Yuan checked the time and said, "Come in for almost 30 minutes, explore for another 30 minutes, and turn around."
The five members of the team continued to move forward.
A few minutes later, Fang Yuan stopped and looked up around.
"what happened?"
"We seem to be back to the original point. This place seems to have passed before." Fang Yuan was not sure because the crystal caves all looked similar.
"Every place here looks the same, are you sure?" Beef Ball doesn't remember at all that he walked through this place just now, or he felt exactly the same everywhere he walked.
Eve swiped with the tablet and said, "We are indeed in a circle. The road we have just walked is turning right as a whole. It is indeed possible to return to the original point."
Han Youwei walked to a crystal cluster to check, and said, "There are indeed marks. We have walked here before."
Eve began to calculate and draw pictures on the tablet, and quickly 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. ."
She said, pointing to the invisible abyss on the 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, with the cave wall on the left and a bottomless abyss on the right.
Use the eyes of the ghost to explore the bottomless abyss, you can't see the bottom.
However, you can see the edge of the bottomless abyss, there are a circle of exposed caves, like rings, nesting on the bottomless abyss.
The cave where the five members of the team are located is one of the circles.
"Don't you want to see the next cave?" Fang Yuan asked everyone their opinions.
"If you fall into the bottomless abyss, there will be no rescue." Ye Zheyu was more cautious.
"All came in, and I didn't find anything. It's boring to go back like this. I support to go and take a look." Eve raised his hand to comment.
After the five people discussed, they finally decided to go to the next cave to continue exploring.
So Fang Yuan made an iron chain, tied it to a crystal cluster, and put it down along the bottomless abyss.
The five buckled the buckles of the combat uniform on the iron chain and slid down the iron chain.
After descending fifteen meters, he entered the next cave.
The team of five continued to explore.
Finally found a star beast lair.
These star beasts were only level 6 or 7, so Fang Yuan attacked decisively and destroyed the star beast lair.
Eve found a small amount of light blue powder in the star beast's lair, and carefully filled it with a small glass bottle, with an excited expression on his face.
The beef moved up, wanting to see what she was doing.
"Go away and kill you if you lose one milligram." Eve threatened.
"what is this?"
"Xingyuan Mine."
The five people gathered around, looked at the light blue crystal powder the size of a thumb cap in the glass bottle, and asked in confusion: "This is Xingyuan Mine?"
"Isn't the ore supposed to be piece by piece?" The beef ball scratched his head.
"This is the Star Source Mine, which was collected by the Rift Star Beast. That's it, it's invaluable." Eve explained.
