A passage that had been abandoned for an unknown period of time looked dark inside. The warriors of the Na Ning tribe seemed to have little interest in it. The areas they cleaned were all above the embankment.
Based on the size of this dam, although the population base of the Na Ning tribe is more than 30,000, it is actually not that many. It just looks quite big compared to the small tribes outside the Dinglong Mountains.
This dike is more than three kilometers long. On weekdays, only more than 200 soldiers can be arranged inside. This also requires patrolling the construction areas outside. In years when there are no attacks by sea monsters, some soldiers are sometimes arranged. Garrisoned outside.
In addition, it is really inconvenient in winter, so there are many places on this side of the embankment that still look very messy.
The main force of the Na Ning tribe is in the battle area with the Red Flame Leopard tribe on the west side.
Ye Qiong took the fire fold and walked into the small passage. At this time, the sky had darkened. Although the stars were still hanging on the top of the mountain, the light could no longer shine on the earth.
The light emitted by Huozhezi reflected back and forth in the small passage, illuminating a distance of about five or six meters in front, and it looked completely dark further down.
On the stone wall, you can see the traces of human beings using tools to repair it. After walking more than ten meters inside, some familiar stone gates appeared on the left and right sides of Ye Qiong!
When those sealed stone gates appeared in front of him, Ye Qiong immediately thought of a place.
It's right next to the waterfall base, where the weapons and equipment left by the ancestors of the Na Ning tribe are stored, and the stone gate above the steps.
They are all sealed up, and depending on the situation, they can also lead to the underground. However, they are too old. Unlike inside the waterfall cave, the stone door above has some gray-brown bacterial plaque around it.
"Bang bang..."
Ye Qiong held the fire folding piece with one hand, raised his right foot, and kicked the sealed stone door several times.
A response came from Shimen immediately, and a low voice echoed in the passage.
The passage looks very deep. The entire embankment is three kilometers long and more than five hundred meters wide, which is about the same width as a V-shaped building.
With this width, many buildings could be crammed into it. Ye Qiong continued to walk inside for a while and found that the small passage was quite deep. The smell inside was getting more and more stuffy, and there was a very strange smell.
If a normal person, such as a warrior from the Naning tribe, smells this smell, he will definitely cover his nose and run back.
But when Ye Qiong smelled this smell, he didn't feel any discomfort. Instead, he curled his lips in confusion and muttered: "Could it be..."
After muttering, Ye Qiong continued to walk inside for a while, and saw a lot of gray-brown and gray-white mold intertwined on the walls on both sides.
When he saw these molds, Ye Qiong showed a smile, this thing...
Finally, he found what Ye Qiong had been searching for all this time.
The first time he went to the altar above the waterfall base, Ye Qiong was intentionally looking for this kind of thing. Unfortunately, the stones there seemed to be made of special materials. Perhaps it was due to the climate. No such plaque was found inside, or in the area where the boulders were stacked up inside the altar.
I didn't expect to find it in the dike base of the Na Ning tribe.
Those intertwined gray-brown and gray-white things are what Ye Qiong has been looking for all these years.
Nitre!
Fire saltpeter!
Those things that appear gray-white under the light of the fire are saltpeter. This thing is also called flame saltpeter. Under normal circumstances, it will appear white or off-white. If it is processed, it can be used as a pigment. Glass can also be made.
at the same time……
It also has a very big use, it is the raw material of gunpowder!
This stuff is also easily soluble in water, colorless and odorless...
Within the passage, on the stone walls on both sides, there are these dense moss-like bacterial plaques. The number is very considerable. If they were all cut off, there would probably be quite a few.
Ye Qiong's original intention when he came this time was to help the Na Ning tribe and resist the sea beasts they mentioned.
I didn't expect that I would gain so much. First of all, the discovery of those monsters with eyes can be related to the eyeless monsters in the cave.
Although these two species cannot be classified into one category, they can be studied as a system.
There is also the sea. Ye Qiong has always wanted to see what the sea looks like above the snow stars, but for a long time, there has been no record within the tribe, and the tribes that have been blocked by the Dinglong Mountains and the dense forests in the south for generations, if not Qingzhi and Qinglie accidentally discovered the water channel. If Ye Qiong wants to rely on the development of the tribe to bypass the Dinglong Mountains or the dense forests in the south, he will really have to wait until the Year of the Monkey and the Horse.
If we pass here now, as long as we have the ability to prevent the attacks of sea monsters from behind, we can directly cross the V-shaped channel behind the dam and expand our marine resources.
Now Ye Qiong's position is already deep in the small passage. If you look ahead, you can see a deep black hole with only a few meters of visibility. This is still the case when Ye Qiong has a fire stick in his hand, and the light from outside can no longer be reflected. .
If you look back, you can actually see the light at the entrance of the cave. At this moment, you just lay your big head on the fallen rocks at the entrance of the cave.
Waiting quietly for Ye Qiong to come out.
Ye Qiong continued to walk forward for more than ten meters, and found nothing else except the saltpeter on the wall and the sealed stone gates.
Pulling out the bone crystal dagger and taking out a small bottle from his pocket, Ye Qiong found a place with more flames and salt and started scraping it.
Soon, the small fired ceramic bottle in his hand was filled with gray-white powder.
Ye Qiong stuffed the small bottle directly back into his pocket and took out a new one.
After getting three bottles, he nodded with satisfaction, turned around and walked back.
Unknowingly, he had walked more than a hundred meters. Now Ye Qiong felt the majesty of this dam personally, and he expected to find many interesting things inside.
After arriving here, Ye Qiong saw the surging eyed monster sea beasts for the first time, and knew that their attack this time would not stop in a short time.
Every time they attack, since the time interval is so long, it means that they must have accumulated a lot of numbers.
Ye Qiong had already made plans to stay at this dike base for a while, and he just happened to take this opportunity to study gunpowder!
Now the tribe has to face many threats, such as the beast tide in winter, the crazy crowds that gather from time to time, the Thunder Madman King who climbed to the heights of the Dinglong Mountains, and the Red Flame Leopard within the Dinglong Mountains. tribe……
Now coupled with the eyed monster sea beasts rushing from the sea at the dike base, these threats require warriors within the tribe to resist!
Therefore, increasing the comprehensive defense power of the tribe is something that Ye Qiong must speed up as soon as possible. Otherwise, let alone taking the tribe to the blue mother star, it may not be developed by that time. In the winter, these real The threat was eliminated.
