"Boom..."
After the hard object fell into the water, it made a thud, and then followed the water flow and fell to the lowest position in the channel at a very wide speed.
Ye Qiong continued to use the bone crystal dagger to dig forward, and now it was obvious that it was very laborious.
I got a piece of hard material that was about the size of my palm and weighed it on my palm. It was very dense.
As for what material it is made of, Ye Qiong is really not sure yet.
Urgent……
If you want some light, you have to at least see what color this thing is.
When he thought of this, Ye Qiong leaned directly on the slope, rested for a while, and climbed down.
Somewhere above the groove, Ye Qiong dug a hole perpendicular to the slope, placed the bone crystal longbow and quiver inside, and went into battle lightly while digging the hole.
After returning here, Ye Qiong took out two arrows from the quiver, held them in his hands and made no movement. He seemed a little hesitant.
After a while, Ye Qiong rubbed his nose, broke the arrow directly from the center of the arrow, stuffed it into the inside of the bag on his waist, and climbed up.
After arriving at the location of the hard object, Ye Qiong took out the arrow from the bag.
One in each hand.
"call……"
After exhaling, Ye Qiong opened the bow with both hands and slammed the two iron arrows together.
"when!"
Following the sound of metal collision, there was a string of small star points with a red shimmer.
Friction will generate a large amount of heat energy. The dynamic potential energy is converted into heat energy at the moment when the iron arrows come into contact, causing the metal fragments that are collided to reach a height of several hundred degrees in an instant, thus producing light!
To be more precise, it is the ultra-high temperature produced by atomic collisions, which is more than a few hundred degrees...
Not only metals, but also stones with a certain hardness will be affected by collision.
This is the reason why flint can be used as a match.
Ye Qiong's eyes had not been exposed to light for a long time. Just the light of some metal scraps made Ye Qiong feel dazzling.
"Dang-dang-dang...!!"
After rubbing his eyes, Ye Qiong hit the two metal arrows continuously at the fastest speed.
The red metal fragments produced continuously appear very bright in the absolute darkness.
Ye Qiong's hands were constantly making alternating movements, and taking advantage of the light, Ye Qiong finally saw clearly the color of the thing blocking him.
off-white.
To be sure, under this kind of light, there will be errors, but Ye Qiong can at least eliminate a lot of minerals.
After stuffing the arrows back into the bag on his waist, Ye Qiong picked up the bone crystal dagger and continued digging forward.
I want to see how thick this thing can be.
An hour later...
Ye Qiong wiped the cold sweat from his forehead, rubbed his arms that were already sore, and discovered a serious problem.
The hard material blocking him now seems to be very deep...
It should be said, thick!
So far, Ye Qiong has only dug forward about twenty centimeters, and the diameter is only ten centimeters...
It could barely fit Ye Qiong's right hand and wrist into it.
Instinct tells Ye Qiong that the back is still very thick!
"Your uncle's!"
Ye Qiong breathed out, lay down on the slope, and couldn't help but curse.
After only resting for a few minutes, Ye Qiong wiped the sweat from his forehead and started digging on both sides...
Since it is so thick, Ye Qiong can only try it first to see how big its area can be.
Holding the bone crystal dagger, Ye Qiong began to dig into the surrounding area. Although Ye Qiong could not dig the things in front of him, the ordinary soil layers in the surrounding area were just a matter of moving his arms.
After a while, Ye Qiong cleared a piece of space. The space where Ye Qiong is now is much larger than the space below, allowing Ye Qiong to easily stretch his arms.
Ye Qiong continued to expand into the surrounding area, but as the area became larger and larger, Ye Qiong's heart became colder and colder.
Two hours later.
Ye Qiong stopped, with a calm expression on his face. Everything up, down, left, and right was extended about two meters by Ye Qiong, but there was no sign of disappearing anywhere.
And Ye Qiong was also shocked by a guess in his mind...
The gray-white obstacles in front of him were very smooth. Now Ye Qiong felt that the probability of these things forming naturally was very low.
Ye Qiong now speculates that what is standing in front of him now...
It's a wall!
The artificial wall was buried under the ground and was very thick and hard. Even if Ye Qiong held a bone crystal dagger, it would be difficult to dig it.
If the thing in front of him was not artificially constructed, Ye Qiong really couldn't figure out how such a flat thing could be formed in nature.
Now that the surrounding space has been dug up by Ye Qiong, Ye Qiong once again touched the barrier in front of him. The more he touched it, the more he felt something was wrong...
The current location is more than 100 meters away from the surface of the pool, and there is a drop of more than 500 meters from the waterfall.
What Ye Qiong is thinking about now is how deep is the huge altar. If it is deep enough, it seems...
It can be completely extended here.
But if this is the case, how powerful the tribe that built this altar must have been at the time!
According to Ye Qiong's current understanding, it is conservatively estimated to be more than 100,000 people.
The wall blocking him in front of him seemed to be synthetic and harder than cement.
This hard and corrosion-resistant composite has remained unchanged beneath the earth's surface for thousands of years.
Ye Qiong adjusted his mentality, and after slamming the obstacle a few times, he turned around and slid to the position where the fish was stored.
While gnawing on the fish, I was thinking about what to do...
If it was really a wall, then Ye Qiong's situation would be really troublesome now. Based on the size of the altar, Ye Qiong roughly estimated that the thickness of the wall was estimated to be more than five meters.
It took a long time just now to dig out a small hole with a depth of 20 centimeters and a diameter of 10 centimeters with a bone crystal dagger. If you want to dig a hole that can accommodate yourself in, it will take several months.
And whether the bone crystal dagger can withstand it is a question.
After eating and drinking, in order to make sure that what was standing in front of him was a wall, Ye Qiong climbed up again and continued to expand around the small hole he had dug just now.
After Ye Qiong dug out an area that was five meters horizontally and vertically, and there was still no end in sight.
Ye Qiong finally concluded his guess, this thing is an artificially constructed wall!
It is harder and more corrosion-resistant than the stone clay soil currently used by the Ye Qiong tribe, and even stronger than cement.
"Protruding!"
Ye Qiong couldn't help but kicked the synthetic wall, and then sat on the slope...
The plan to dig a hole was in vain. Now Ye Qiong felt that he had been blind for so long.
