Looking at the three huge gears in the hall, Ye Qiong thought of the stone gates in the three large passages.
The existence of these iron chains and gears are all prepared to pull up the stone door.
No wonder it takes dozens of warriors to pull the iron chains at the same time to pull up the stone door in the large passage!
When Ye Qiong saw these chains and gears with his own eyes, he felt...
It is not easy for dozens of people to pull up the stone door below. It requires a tall warrior. Otherwise, the weight of the iron chains alone is heavy enough.
That gear should be able to play the role of some fixed pulleys. There are probably some smaller pulleys connected below, which can adjust the transmission ratio of kinetic energy when transmitting the force, so that these dozens of warriors can move together With force, the stone door can be pulled up.
The distance between the gears is about fifty meters, and it seems that the distance between the stone gates between the large notices below is the same.
Thirty meters away directly opposite the three large gears, three large stone pillars stood.
The three stone pillars are of the Tongtian Pillar type and are directly linked to the top dome. Each stone pillar is about five meters tall and looks very thick.
On both sides of the three large stone pillars, there are two smaller stone piers next to each other. Each one is about three meters high and two meters wide. There are many threads on them, which seem to be used to fasten those large iron chains.
As long as the large iron chain is tied to these two stone piers, and then wrapped around the large pillar, a very stable structure is formed, which can ensure that when the iron chain can bear enough load, the stone door below will never be damaged. It will fall.
Nearly a hundred warriors divided into two waves and came to the two wings of the first gear. With the help of more than a dozen forest apes, they pulled up the two iron chains directly.
Two large iron chains converged and intertwined in front of the giant gear, forming a larger iron chain...
As the iron chain was gradually tightened, the whole body slowly lifted up. As the iron chain in the middle area left the ground, it began to approach the straightened state.
But before the iron chain was tightened, the giant gear began to move.
As the giant gear rotated, a deep sound came from the large passage below, and the stone door began to slowly rise...
Ye Qiong was just looking at this magical scene. The tribe that built this place was highly civilized, at least it had reached the peak of the cold weapon era.
When the first stone door in the first large passage was pulled up, it didn't take long for the stone doors in the second and third large passages to be pulled up as well.
They are all facing the stone gate within the Dinglong Mountain Range.
Within the three large passages, a total of nine stone doors were slowly lifted up one after another.
In order to prevent the stone door from being unable to be pulled up, the stone door on the side within the Dinglong Mountain Range, that is, the outermost stone door, is not immediately adjacent to the outer wall, but extends about ten meters inwards.
However, within this ten-meter passage, there are also corpses of sea beasts, and there are quite a lot of them. In the lowest area of the stone door, red ice crystals are directly connected to the stone door, so this last door was just opened At this time, it was very laborious, and the iron chains seemed to be stretched straight, and then the stone door was slowly pulled up.
The ten-meter buffer area formed an upward slope, which was made up of the corpses of sea beasts.
These sea beasts were either squeezed to death or suffocated.
When the bottom area of the dike was sealed by the corpses of sea beasts, there was no ventilation inside. The stone door and the upper wall were close together without any gaps, so the sea beasts in the buffer area would never think of it. There is actually such a large space above his head, and the stone door that completely blocks them can also be pulled up.
Outside the buffer zone of Shimen is an area completely blocked by the corpses of sea beasts. It is very high. Now these sea beast corpses can only be transported to the Dinglong Mountains through large channels.
After all the nine stone doors in the three large passages were pulled up, the warriors of the Na Ning tribe began to walk inside.
It is not dark inside the large passages. In the years when there were no sea monster attacks, these passages still played a role in connecting the inside and outside of the Dinglong Mountains, so there were grease lamps hung up by the warriors of the Na Ning tribe.
The cleaning work has begun...
Ye Qiong came here purely out of curiosity and wanted to see what else was worth studying in this dike base. He had no intention of helping at all and did not bring any warriors from his own tribe.
This kind of physical work should be left to the soldiers of the Naning tribe. Under Ye Qiong's instructions, Huahuangji took the soldiers who had not rested and entered the small passage under the dike base. Went to scrape the flames and saltpeter.
After seeing the power of the iron pot bomb, everyone was very excited and wanted to move the dam base directly back.
Three days later...
Under the dike base, inside the wooden house base, there are ten sacks neatly placed next to the wall!
The sacks are not full, they are all half sacks.
The density of flame salt is still quite high. In the dusty state, half a sack of flame salt is already very heavy.
Ye Qiong's current plan is to ask each soldier to bring half a sack with him when he goes back.
If there are too many, it will affect the marching speed of the Snow Demon Wolf. It is too heavy!
As for whether eighty sacks of flame salt could be scraped off, looking at it now, it was not a big problem. Ye Qiong took the time to go into the small passage and made a rough comparison based on the current output and the remaining areas that had not been scraped. The storage capacity of flame salt is still considerable.
But time may not allow it. In three days, so many warriors registered ten copies in total. If you want all 80 warriors to bring flame salt, you will need to stay at the dike base for at least more than 20 days. .
If we count the time now, nearly ten days have passed since Ye Qiong led the soldiers out of the wooden house base.
Coupled with the journey back, Ye Qiong's plan is to stay here for about a week and then take the soldiers back...
Ye Qiong did not plan to bring too much fire salt back this time. It was not that he planned to leave it to the Na Ning tribe, but he was worried that if he brought too much, if something happened on the way, the loss would be too great.
It is absolutely safe to leave the flame salt in this small passage. No monster will care about this thing. With the current relationship between the two tribes, as long as Ye Qiong explains it, I believe the Na Ning tribe will not have any evil intentions. They Even if he really had some evil intentions, Ye Qiong actually wasn't worried.
Black powder, if used well, can indeed work wonders in defensive battles, but in battles between humans, its effect is not that great. Its power is very limited, and Ye Qiong will not panic. When leading troops to attack their big shell base, in wild encounters, the effect of black powder may not be as great as that of a giant crossbow.
If they had the ability to develop fire blunderbuss, they would be considered powerful, but in fact, their power is just that. Within a certain distance, even the arrows shot by the ancient forest apes cannot match the power of the arrows.
So after Ye Qiong thought about it, he decided to take thirty copies back for research and leave the remaining flame salt here. If needed later, just come over and continue.
This thing cannot be greedy, it must be worked on steadily. After these flames and salts arrive at the central tribe, they must be controlled strategic materials, and normal tribesmen cannot have access to them.
Two days later, one of the three large passages under the embankment base was finally dredged. Looking down from the top of the embankment, you can see a funnel-like blank area appearing in front of the large passage in the middle. Connected to the large passage.
At the same time, Ye Qiong also gathered a small team of twelve people next to the wooden house under the dike base, planning to go to the V-shaped passage to have a look...
