About seven kilometers away from Gaoqi volcano, Chen Jing stopped by a pond.
There are actually many ponds in the mountains and forests surrounding Gaoqi volcano.
The depth of most ponds does not exceed three meters, and the deepest lake is just over eight meters.
But the pond in front of me, which is only 5 meters in diameter, is more than 20 meters deep!
And there is a crack in the deepest part.
Fortunately, Chen Jing was very careful in detecting each pond, otherwise he would have missed it.
This pond appeared due to geological activity.
Its chasm leads to an underground river.
However, the gap was not wide enough for Chen Jing to pass through.
But Chen Jing decided to dive down first to find out. After all, at the crack of the underground river, the bioradar could no longer detect the situation on the other side.
The water in the pond is cold and not the underground hot spring as expected.
The bottom is clear, but there are no aquatic species here.
Since he had never dived at this depth before, Chen Jing climbed down holding on to the exposed gravel at the bottom of the water.
This pond created by geological activities was not easy to descend into. When it reached a depth of 15 meters, Chen Jing found that he could not descend.
It's getting narrower.
If you dive forcefully, you will get stuck.
But bioradar can already detect more information.
The width of the underground river exceeded Chen Jing's imagination.
The width is more than 15 meters, while the length can only be detected to about 200 meters.
"I won't find anything strange, right?" Chen Jing was secretly shocked.
The ridiculously active geological activities of the Hengda Continent have created many strange sights. No one knows how many such underground rivers there are.
Where it leads, no one knows.
Chen Jing saw this natural scene for the first time in his two lives, and was naturally shocked.
And even better news shows up in bioradar.
The connection between this pond and the underground river is not at the upper end of the underground river, but at the bottom.
In other words, there is actually an underground river beside Chen Jing.
But the hard earth and rocks prevented further penetration.
After staying underwater for a long time, Chen Jing finally came up after feeling a little lack of oxygen.
"55 minutes. The time to stay still underwater is 55 minutes." Chen Jing looked at the time on the system and determined his plan.
That means chipping it away!
He had a strong feeling.
There is something you want in this underground river.
But before digging, Chen Jing decided to search all around.
Wouldn't it be better if there was an easier way to enter?
After three days of searching, Chen Jing was disappointed.
Apart from the crack in the pond, there is no other way to enter the underground river.
After finding a lot of iron tools from the small town and building a simple hut by the pond, Chen Jing was ready to stay here permanently.
When you are hungry, you go to look for the giant antelope, and when you are thirsty, you go to the surrounding ponds to drink water.
Chen Jing had no intention of drinking his own bath water.
The best way to open a passage to the underground river is actually to expand the crack.
After all, it only requires widening the cracked earth and rock around it.
This body is already very powerful. Even in the water, Chen Jing can still perform very well.
The banging of chisels continued in the water.
It only took Chen Jing one day to cut the last five meters of tunnel down to only four meters.
But the further down you go, the more difficult it becomes. Because there is more rock to be cut, it takes longer.
This is nothing to Chen Jing.
He has plenty of time.
And the closer he got to the crack, the stronger Chen Jing felt in his heart.
He didn't know if it was a psychological factor or something else, but he always had the feeling that he would find something as long as he entered the underground river.
However, within the range that bioradar can detect, there is nothing.
Time passes quite quickly.
Chen Jing came to Qixing for two months.
It took half a month to cut the stone.
Those who didn’t know thought he had traveled through time to work as a miner.
It was only a day or two before the crack in the underground river was opened.
Sometimes Chen Jing wishes he could be thinner so that he could pass earlier.
ashore.
Inside the cabin were some mattresses brought from a small town.
Outside the wooden house, there is a giant antelope tied with a thick hemp rope. This was specially captured by Chen Jing to better assist him in digging holes.
Chen Jing tied a hemp rope around his waist, took out the remaining awl and chisel, and walked to the pond.
In the past half month, Chen Jing spent at least more than 12 hours in the pond every day.
Perhaps the same is true today.
Skillfully dive underwater.
In so many days, Chen Jing's water quality has improved a lot.
The reason why the final crack was so difficult to cut was simply because we couldn't find a suitable starting point.
Chen Jing could only move his head up and down, put his hand into the crack, and used biometric radar to determine where he had struck.
The three factors combined, the small space, handstands, and stone chiseling, forced Chen Jing to leave after less than half an hour each time.
This was after he had once again evolved his lungs.
Under normal conditions, Chen Jing can now stay in the water for an hour and a half.
Imagine that you are now in a space that is the width of your body.
Just imagining it gives most people a suffocating feeling.
Being in a small space, the psychological uneasiness is the main reason why Chen Jing can only stay for such a short time.
After pulling the rope straight with your feet, the iron sheet on the shore will make a sound, and the giant antelope who heard the sound will start to pull the rope obediently.
In this way, Chen Jing can quickly get out of this small place.
This is what Chen Jing came up with after being stuck for ten minutes while retreating.
The giant antelope is also surprisingly tractable.
Every time after coming up, even if the oxygen storage is completed, Chen Jing still has to spend some time to get rid of the uneasy feeling.
After touching Reserve Liang's head, Chen Jing named the giant antelope Reserve Liang.
Reset the pulling mechanism and launch into the water again.
The closer to the underground river, the wider the range Chen Jing can detect.
The detection capability of underwater bioradar has been weakened, but it is still at least 500 meters away.
Counting from the crack, there is no living thing for 500 meters before and after.
There is only water.
The water flows from left to right, because the direction of Gaoqi volcano is on the right, so Chen Jing will go downstream first to take a look.
The banging sound was heard far away in the water, but no creature came here to meet Chen Jing.
The last time I was pulled up, it was already night.
When Reserve Food saw Chen Jing walking into the cabin, he lay down quietly and fell asleep.
In order to protect the safety of the food reserves, Chen Jing surrounded it with a circle of saber-toothed wolf heads.
But this may also be one of the reasons why the food reserves dare not run away.
The next day.
As soon as the sun rises, Chen Jing goes into the water.
When the last rock was broken, Chen Jing couldn't wait to explore the underground river.
The coldness of the river caught Chen Jing off guard.
But what was even more unexpected was that as Chen Jing's upper body entered the underground river, the rope around his waist straightened.
Hearing the collision of iron sheets, Reserve Liang started to pull him, and forcefully pulled Chen Jing back.
Looking at Reserve Liang's ignorant eyes, Chen Jing didn't know what to say.
But even if he wanted to say it, he couldn't say it.
Finally, after hanging the heads of the two saber-toothed wolves on the corners of the food reserve, Chen Jing untied the rope from its body.
"Let's go!"
After patting the head of the food reserver, Chen Jing turned around and entered the pool.
The grain reserve waited in place for a long time, but no more sound of iron sheets was heard.
Spring passes and autumn comes.
In the spring of the next year, a group of giant antelopes came to the waterhole.
On the head of the leading giant antelope, two heads that were already white bones hung.
