After Ye Qiong jumped off Thunder's back, he jumped directly from the dam again without any pause.
A ten-meter-high dam is naturally nothing to Ye Qiong. There is a distance of about thirty meters from the bottom of the dam to the edge of the waterfall. This area is now paved with stones.
The waterfall here is almost vertically downward. Now for the dam above the edge of the waterfall, the more fearful thing is landslides.
However, there are dense forest areas on both sides of the waterfall, and there is a certain slope buffer zone. Unless there is a large earthquake or a long period of heavy rain, the structure is still very stable.
There is no way to avoid natural disasters and man-made disasters. We can only build the dam as wide as possible to make the force on itself more even.
On the stone-paved ground, some wooden stakes with a diameter of more than one meter were placed in front of the waterfall in order to extend the vines to the entrance.
Those wooden piles are still in place, but there are now more circles of stones around them. They are already very stable, unless it is the case where the waterfall collapses as a whole.
Otherwise, based on the weight of the vines and wood that have been completely dried, the weight of these wood is absolutely sufficient.
Time has passed. Now, between the upper edge of the waterfall and the waterfall cave, in addition to the original vines, the soldiers also built some mixed ladders of hemp rope and wood, some of which were fixed on the wall.
So now from the edge of the waterfall cave to the bottom of the waterfall cave, there is no need to hold the vines and descend like at the beginning. There is already something under the feet that can be stepped on to receive the force.
When steel and iron tools are limited, wood is the best building material. It is not easy for the current Ye Qiong tribe to build such a relatively safe vertical cableway on such a cliff.
Ye Qiong went down to the waterfall cave alone from above.
There are soldiers and tribesmen building fortifications on the other side of the dam, but in the area that has been established, there is no need to arrange for soldiers or tribesmen to guard it.
This time entering the waterfall cave, Ye Qiong's mentality also experienced some subtle changes.
Once again, I couldn't help but have a fantasy in my mind, which was the huge particle collider based on the entire Dinglong Mountain Range!
"Huh... I must have been overthinking it..." Ye Qiong breathed a sigh of relief, then jumped directly from the connection between the vines and the wooden board to the protective wall at the edge of the waterfall.
In order to know the situation below the waterfall base as soon as possible, there are still several soldiers taking turns on duty at the entrance of the waterfall.
If an emergency occurs in the Waterfall Cave, it can be reported to the bottom immediately.
In addition to a few soldiers, various supplies and food are also placed in some areas inside the waterfall cave, as well as black iron sand collected from the space on the left.
When he came to the mural, Ye Qiong still stopped and looked at it for a few times, then turned and walked towards the left passage.
The light in the passage is now much brighter, and the air is filled with the unique smell of burning grease.
It's not fragrant, nor smelly, just a bit fishy.
After walking a little further inside, you quickly get used to the smell.
Just like for shepherds and cattle herders, when entering the cattle and sheep pens, they will not actually feel any smell, only the fishy smell. Most of the feces of herbivorous animals are not smelly and are air-dried. After that, it becomes a natural reserve energy, which can be used as wood and coal.
Nomads used them to make fires and cook.
Most of the grease in the barrel grease lamp is extracted from the eyeless monster, and the smell after burning is that fishy smell.
As long as the tribe doesn't have any major problems with food supply in the future, Ye Qiong doesn't want his tribe members or even the tribe's guardian beasts and snowy demon wolves to eat the meat of those eyeless monsters.
But it can’t be wasted. The number of eyeless monsters killed by the cave defense line every month is still very impressive. While cooking the oil, the minced meat is also stored. Ye Qiong’s plan is to use it directly as fertilizer in the future. use.
In fact, there is another use, which is to crush it together and burn it directly as the bottom material of the biogas pool.
Now the tribe has no shortage of energy, and coal is enough for daily use. Therefore, Ye Qiong has not put this plan on the agenda. However, with the gradual improvement of the pyramid living area, central heating has also been put on the agenda. If biogas can be used, Pools provide central heating to the pyramid's residential areas, which is much more efficient than coal.
The most important thing is to be environmentally friendly. After all, coal is a non-renewable resource, and those eyeless monsters...
Ye Qiong now wishes that they would be extinct quickly, so that there would be one less security risk for the central tribe.
Following the passage on the left, after turning a corner, you came directly to the cliff area.
The light of the grease lamps is still limited. Although many wooden barrel grease lamps have been lit in the passage here, outside the cliff, there is still a kind of void darkness.
Under the void space, the pontoon bridge that extended far inward like a long snake also appeared in front of Ye Qiong.
It seems to be quite large, but no one knows when it will reach the other side.
Ye Qiong can't even imagine now. If it were really a particle collider based on the Dinglong Mountains, how huge it would be. The cross-section of any area would be an architectural miracle for humans. .
With the support of the spirit of exploration, while ensuring safety, the exploration inside the waterfall cave will not stop.
The warrior in charge of the space on the left is also an old warrior of the Yuanfan tribe. His name is Hua Yu. He is about forty years old. He is on the left and right of Tang Li. He is now responsible for handling everything in the waterfall cave.
Tang Li is in charge of the female soldiers on the right side, and Huayu is in charge of the male soldiers on the left side. If an emergency occurs at the waterfall base, Huayu will be in charge of the command.
Huayu is currently on the pontoon, directing the soldiers to continue extending the pontoon.
Standing next to Ye Qiong were two younger warriors from the Yuanfan tribe, who were already very familiar with Ye Qiong. They were talking to Ye Qiong about the development of the space on the left side of the waterfall cave these days.
The pontoon continued to extend for a certain distance, but the breakthrough point was that in addition to extending a little further to the front, it also extended for a distance to the left and right sides just below the cliff.
When Ye Qiong heard this, he immediately took them down, wanting to see what the walls on the left and right looked like up close.
If Ye Qiong's thoughts about the Dinglong Mountains are true, it means that the civilization that built this space is already very advanced, at least hundreds of years ahead of Ye Qiong's Earth era.
So there will definitely be some traces left on the wall...
