"Whizzing……"
Ye Qiong continued to shoot two lantern arrows out, and the inside became brighter.
The two arrows went to both sides and were inserted diagonally into the wall. Ye Qiong also determined the width of the space inside.
About twenty meters, that is to say, the area of the space inside is about 600 square meters.
The pool in the middle is half the size of a basketball court and a half.
Ye Qiong is still very curious about the black objects stored on both sides and what is in the pool.
However, the hole can only barely allow people to put their heads in, but their bodies cannot go in.
If you want to get in, you still have to wait a few days.
After putting down the black long bow, Ye Qiong took out the bone crystal dagger and scraped a few times on the edge of the hole, scraping off some broken particles.
The stone door is still very hard and has strong toughness, which is not comparable to walls made of concrete.
If it were just that kind of concrete wall, the soldiers would not need chisels or axes at all, they could just use swords to break it open in a short time.
After scraping a few times, Ye Qiong stopped and resisted the idea of using the bone crystal dagger to make the hole larger.
Continuing to ask Tang Li to arrange for people to smash the stone gates, Ye Qiong walked around the waterfall cave on the right and looked at the other stone gates that had been smashed deeply.
Then climb directly up the passage and come to the left side of the waterfall cave.
The iron-sand pontoon bridge below has been built further recently. Under the light, the pontoon bridge above the iron-sand bridge is like a mysterious passage at night, extending towards the seemingly endless darkness of the void.
At the edge of the passage on the left, bundles of wooden piles and wooden boards are neatly placed together, all pulled up from the base of the waterfall.
Now a lot of trees outside the wooden house base have been cut down, and there are more and more buildings inside the base, and the peripheral defense zones are also being pushed out again and again.
Ye Qiong carried a bundle of upgraded arrows and came to the end of the floating bridge.
The soldiers were still constructing, and wooden piles were driven into the black iron sand one by one to act as a support. After they were driven to the extreme position, wooden boards could be built on top.
"Ding ding... bang bang bang..."
Noisy sounds rippled around. In order to ensure the safety of the wooden bridge, there were some soldiers behind Ye Qiong who were busy reinforcing both sides.
From a macro perspective, if you look at it from the front, you will feel that this scene looks familiar...
When Ye Qiong fell into the water channel, Ye Tianlong led his soldiers to build a large floating base on the water using vines.
Now on the black iron sand floating bridge, hemp ropes as thick as an adult's thigh were pulled from the cliff and became the hanging points of the floating bridge.
Under double protection, it is still very safe on the pontoon and there will be no quicksand effect.
The range of the lantern arrows that need to be ignited first has a limited range. After the upgrade, the range of the lantern arrows that can be lit directly with the fire wick is greatly increased. After adding some windproof tunnels, there is almost no need to worry about shooting. If the speed is too fast, the sparks will go out in mid-air.
Ye Qiong directly took out the bone crystal arrow from his back this time.
He directly twisted open the cover of the wick on the lamp arrow, placed it on the bone crystal long bow, and shot an arrow.
"Whoosh!"
After using about three times of force, the arrow started to fly in the air after leaving the string. After a few seconds, the originally inclined upward trajectory began to slowly become parallel, and then the arrow began to tilt downward...
As the arc gradually increased, it finally landed on the black iron sand below.
"puff……"
Hundreds of meters away, a bright flame jumped out with a flutter.
Ye Qiong looked at the flame that had turned into a small dot, couldn't help curling his lips, and shook his head helplessly.
This distance...
It's indeed a bit scary, and what's even scarier is that this is inside a cave, not the outside world.
Although such a large space is not worth mentioning for the Dinglong Mountain Range, which is tens of thousands of meters high and more than ten kilometers wide.
But in such a non-load-bearing area, the force that the dome needs to withstand is very terrifying.
What is certain now is that this space is much larger than the one on the right side of the waterfall cave!
There are still a few large stone pillars on the right side for support, but here, so far, Ye Qiong has not seen any support points.
Ye Qiong continued to take out the lantern arrows, and with the front lantern arrow as the center, he shot three arrows to the left and right sides!
"Whoosh whoosh whoosh..."
After the six arrows were shot, both sides became brighter. Ye Qiong still did not see any supporting stone pillars.
"Can such a large space be formed naturally..."
After the seven lantern arrows were shot, there were three left at Ye Qiong's feet, but he still did not intend to continue shooting. Instead, he looked at the lantern arrow in the center in front and muttered.
Naturally formed caves have a limit to the force they can bear. Even if you don't consider the impact of earthquakes, let alone a few hundred meters.
When Ye Qiong was on Earth before, he traveled to the Tenglong Cave in China during his vacation. At that time, he felt that the cave, with a mouth more than 60 meters wide and a height of more than 70 meters, was very shocking. It was also very long inside. It is nearly ten kilometers long, and the underground water tunnel is even more than ten kilometers long.
Although it is comparable to the space on the right side of Waterfall Cave, it really pales in comparison to this dark space now.
The history of this space must be very long, at least it is the same period as the right side of Waterfall Cave, which is at least three thousand years. The upper limit is immeasurable.
He must have experienced many earthquakes in such a long time. On the west side of the Dinglong Mountains, Ye Qiong has personally experienced no less than five major earthquakes in recent years!
Sometimes it happens once every few years, sometimes twice a year.
There have probably been many super earthquakes over the past three thousand years, but this space still exists.
Ye Qiong really couldn't believe that it was formed naturally, but if it was dug out by man, it seemed terrifying!
At least with Ye Qiong's current understanding, he couldn't figure out how such a large space could be carved out manually.
The seven lantern arrows were burning quietly on the black iron sand. There was no wind, so the flames were vertically upward. The first arrow shot directly in front had already dropped by half. The black iron sand Slowly submerged into the grease lamp area of the lamp arrow.
After shrugging, Ye Qiong picked up the three lantern arrows at his feet, held them in one hand, and walked back while shaking them gently.
In the black iron sand area, ten kilometers away to the left of the cliff edge, in an absolutely dark environment, the calm black iron sand surface suddenly fluctuated, like waves, began to surge around, and passed hundreds of meters away. , the fluctuations gradually dissipated...
