Qing Zhi immediately turned her head and looked at Ye Qiong curiously and asked.
Ye Qiong retracted his gaze from looking at the blue Jupiter, looked at the curious Qing Zhi and said, "You have to drive a spaceship to get there."
"What is a spaceship?" Qing Zhi then asked.
"It's a kind of ship that can fly in the sky, a very big one..." Ye Qiong made a casual gesture.
"Oh..." Qing Zhi naturally didn't understand. The chat content between the two people was not in the same channel.
"Let's go, let's see if we can get something up from under there today." Ye Qiong raised the triangular iron tool in his hand and said.
The two climbed up the waterfall, followed the vines above, and returned to the waterfall cave. After entering, they went straight to the cliff on the left side of the passage.
After tying the safety rope, Ye Qiong, with the help of several soldiers, gently shook the hand in his hand.
After a while, the triangular iron tool began to spin rapidly in Ye Qiong's hand. When Ye Qiong felt that the speed was almost up, he suddenly let go of his hand.
The triangular iron tool immediately flew towards the cliff underground, and the hemp rope connected to the tail was coiled together and began to rise upward in circles.
After about six seconds, the rising speed of the hemp rope suddenly slowed down, and Ye Qiong stepped on it directly.
After bending down to pull up the hemp rope, Ye Qiong began to pull it back.
The hemp rope thrown out is quite long, so it is also very heavy. Fortunately, Ye Qiong is very strong and can pull it.
In order to prevent the hemp ropes that Ye Qiong had pulled up from getting tangled together, the soldiers dragged their horses back a little behind Ye Qiong, and then directly wrapped them with a wooden stick.
As the hemp rope gradually shortens, the force Ye Qiong needs to use also becomes smaller and smaller.
About five minutes later, a dark thing appeared from the edge of the cliff.
It was the triangular iron container that Ye Qiong threw down. Now it was not empty, but full.
Everyone's eyes were on the triangular container that popped up, and Ye Qiong carried it over.
After walking into the passage for a while, he squatted down and looked at the things inside. He first touched his chin, then stretched out his index finger and tapped it lightly.
What’s inside…
It was similar to what Ye Qiong had guessed before. It was a soft thing, and it was in small pieces.
Black sand!
Ye Qiong thought of something in his heart, and the frequency of his heart beat suddenly increased.
This black sand seems to have something to do with the weapons and equipment in the right channel.
Ye Qiong pinched a little bit and made a gesture of counting money. The texture of the black sand was quite hard.
Ye Qiong is already a little excited now, even more excited than when he discovered those black weapons and armors in the right passage!
If those black weapons were made from the black sand, and if there was a considerable amount of black sand below, Ye Qiong would have solved an urgent problem.
Ye Qiong directly grabbed a handful of black sand in his hand, weighed it gently and felt the weight.
Compared with ordinary sand, these black sands are obviously much heavier.
In other words, the ingredients inside must be different. It seems that the iron content is very large.
This waterfall cave brings more and more surprises to Ye Qiong.
As the saying goes, teaching a man to fish is worse than teaching him to fish!
Ye Qiong now needs to do an experiment immediately, that is, to see if iron can be extracted from these black sands, and if so, how much is the content.
In the eyes of Qing Zhi and the soldiers around Ye Qiong, what Ye Qiong held in his hand was just a handful of black sand.
Only Ye Qiong knew in his heart what these black sands meant...
"It's black sand. No wonder the lantern arrow lost its light when it fell. It seems that it was swallowed up by the sand." Qing Zhi looked at the black sand in Ye Qiong's hand and said.
"Good stuff!" Ye Qiong adjusted his mood and put the black sand in his hand into the iron triangular container.
Qing Zhi pouted. She knew very well that she didn't understand many of what Ye Qiong said, so she stopped asking.
"Let's go! Go down and do an experiment. If it succeeds, your dream of flying to the blue mother star will be a big step forward." Ye Qiong stood up immediately, picked up the iron container, looked at Qing Zhi and said.
After finishing speaking, Ye Qiong was still a little excited holding the iron container and walked towards the entrance of the waterfall.
Qing Zhi nodded and followed Ye Qiong.
Directly from the entrance of the waterfall, along the vines, went down to the waterfall.
After landing, Ye Qiong trotted back to the wooden base, but before he got there, he showed a smile.
On top of the wooden house where he lived, Ye Qiong saw a little guy, Thunder!
I guess I was tired from flying, so I was standing on the wooden house now. After seeing Ye Qiong, I spread my wings and flew towards Ye Qiong.
Ye Qiong didn't have time to drag it away. He had more important things to do now, so he continued to speed up his pace. When he saw something in Ye Qiong's arms, Lei Lei narrowed his eyes curiously and hovered over Ye Qiong's head.
His eyesight was quite good, and he knew that Ye Qiong had no time to care about it, so he kept flying in the sky and never came down.
He followed Ye Qiong directly to the wooden house and continued to stand on top of the wooden house.
The door of the wooden house was open, and it didn't seem to have any intention of entering.
Ye Qiong dove directly into the wooden house, took out some things with a clank, and then came to the stove outside.
Qing Zhi followed behind, and the few soldiers who followed also came to the wooden house out of curiosity and watched Ye Qiong get busy.
The coal that was put in in the morning was already burning red.
Ye Qiong put the iron container directly on top and started cooking it to see how much of the stuff inside could melt.
Normal sand will explode at high temperatures, while iron will melt at high temperatures.
If it were on the earth, the melting point of iron would be about 1,500 degrees, but here is a snow star, and it is not certain whether the metal elements contained in it are iron. For the time being, Ye Qiong treats it as iron.
Even the same type of iron actually has different melting points under the atmospheric pressure of Snow Star, so Ye Qiong himself didn't bother with this, and Qing Zhi and the soldiers around him didn't even understand.
Of course, they will not have nothing to do and worry about these things, unlike those Internet trolls on the earth before Ye Qiong, who had to read a novel as a textbook.
In the Ye Qiong tribe's laboratory, there is a bellows made by Ye Qiong himself, which can make the temperature of the coal higher.
Ye Qiong's current attitude is to try it first. If it fails to melt, he will go back to the tribe to continue research, or get a bellows here.
About twenty minutes later, the results came out.
A result that Ye Qiong could never have imagined...
These black sands...
It's not sand, but...
Metal!
The pure kind, Ye Qiong saw with his own eyes that the black sand inside was completely melted!
"Surprisingly...it's not naturally formed. What kind of tribe is this tribe? And where did they get all this black sand..."
