This plan is not complete. The routes shown have all been detected by the outpost, and the blocked passages are also among them. However, the three passages leading to the mining area have been blocked by huge rocks, so that this plan
The map can only be used as a reference, and the access to the mining area must be re-explored.
Everyone studied the floor plan and found that after sneaking along the original passage for about RU0 meters, there was an open area. Of course, this open area had been submerged by underground river water, forming a large lake.
The map shows that there are several passages around the open area, skipping the blocked passages, and several other passages have been explored, but at the end of these passages is a rock wall of unknown thickness, making it impossible to move forward.
As for the other passages, the ends are not marked. However, the depths of the passages extend in all directions and there are many forks. The area detected is only a small part. How deep are these passages and where do they lead? There are no clear markings on the map.
After some research, Ning Xiaofan and others selected two passages. These two passages have no end. Most of the areas are shown with shadows, indicating that they are unexplored areas. Fortunately, the direction they are going and the mining area are
In agreement, if we can find an exit, I believe that even if we deviate from the mining area, the distance will not be far.
After discussing the route, Lao Wang and Xiao Shanzi brought in a large wooden box. At the same time, members of the prospecting team composed of foreigners also brought in a large wooden box.
The two prospecting teams were in the same board room. Perhaps because of the competitive relationship, the two parties did not communicate verbally, but just looked at each other secretly. As a beautiful and charming woman, Aunt Xiang naturally has extraordinary
Due to the attraction, the eyes of several foreign men kept wandering on Aunt Xiang's beautiful face, and the lust in their eyes could not be concealed at all.
Ning Xiaofan noticed the covetous looks shown by those foreign men towards Aunt Xiang, and felt unhappy for no reason. However, this outpost was a safe area, and the use of force was strictly prohibited. Ning Xiaofan could not get angry, so he could only suppress his inner feelings.
Not happy.
The large wooden box contains a complete set of diving equipment, respirators, air tanks, diving suits, frog feet, goggles, etc., all available for each person.
After everyone received the diving equipment, they first packed their backpacks, weapons and other belongings in waterproof bags, and then vacuum-compressed them. Then they entered the temporary changing room converted from a board room and changed into the diving equipment.
When everything was ready, Ning Xiaofan and Aunt Xiang walked towards the dark river under the guidance of a permanent staff member.
Before entering the water, the staff member asked Ning Xiaofan and others if they knew how to dive. If someone did not know how to dive, they would need to undergo simple diving training.
As a blasting expert, Ning Xiaofan has worked underwater and is no stranger to diving. However, Aunt Xiang has served as an overseas mercenary. Diving is a necessary subject, so naturally there is no need for further training. This makes Ning Xiaofan feel a little surprised.
What's surprising is that Fatty, Hou San, Zhang Chun, and Chen Biao, four undistinguished guys, can actually dive, which really impressed him.
In addition, Yang Hai can also dive, and only Lao Wang and Xiao Shanzi can't.
The staff member immediately called Lao Wang and Xiao Shanzi in front of him and explained the breathing method of diving, precautions, etc. Finally, he went into the water to give a demonstration himself, and then called Lao Wang and Xiao Shanzi into the water to get used to it.
After a while, it took less than a minute, and the diving training was complete.
Of course, this underground river is no better than the sea. The hydrology and geography are not complicated, and there are no undercurrents or undercurrents. The danger is not great. After this simple training, Lao Wang and Xiao Shanzi can actually go diving. In addition,
There is also a hand-held power-assisted thruster, so you don’t have to worry about the two of you not being able to keep up with the team.
After Lao Wang and Xiao Shanzi barely adapted to diving, they saw the prospecting team composed of foreigners also coming to the water's edge. The location of these foreign men was on the side of the flooded channel.
The foreign men seemed to know how to dive. When they arrived at the water's edge, they went straight into the water and disappeared quickly.
Ning Xiaofan glanced over there a few times, frowned and asked the staff member: "Excuse me, which route did those people take?"
The staff member replied: "The route they take is different from yours. There is only an underwater passage less than a meter long from here. There is an underwater monitor installed at the exit of the passage. They dare not mess around and go out of that passage."
Channels are open water, and there are many channels under the water. You only need to enter the pre-selected channel, and you don't have to worry about meeting them."
Ning Xiaofan smiled noncommittally. He was not worried about meeting those guys underwater. For him, even if they met, it was not certain who would win. He just didn't want to cause trouble on the way to find the exit of the mining area.
To be on the safe side, Ning Xiaofan planned to wait for a while and let Lao Wang and Xiao Shanzi get more familiar with their diving skills.
Not long after waiting, Ning Xiaofan saw a faint flashlight coming through the entrance to the outpost. Then he saw a staff member not far away who turned on a flashlight and shined towards the entrance. It was estimated that another prospecting team had arrived.
Already.
A new prospecting team was about to arrive. Naturally, Ning Xiaofan didn't want to meet a team with unknown enemies and friends, so he decided not to wait any longer and immediately called for everyone to go into the water.
After going down to the water, since there was still some distance from the entrance of the passage, Ning Xiaofan and others swam in their sleep for a while until they reached the entrance, and then swam down.
With his whole body submerged in the water, Ning Xiaofan turned on the overhead lights and started the underwater thruster. With a slight motor sound, Ning Xiaofan held on to the thruster and dived into the passage first.
With the help of propellers, you only need to maintain your body balance to move forward quickly. Even if everyone carries a lot of weight, they don't feel the slightest effort. Soon, everyone exits the passage one after another.
After the passage, the water area became wider and clearer. Ning Xiaofan looked around and could clearly see the scenery under the water under the light of the overhead lamp. At this time, Ning Xiaofan was surprised to see,
There are actually many aquatic creatures in this water area. Groups of small silver fish are wandering around, gathering and scattering. There are even large or small jellyfish-like plankton floating not far away.
I raised my head and glanced at the water. I could vaguely see the uneven dome, and even a lot of stalactites hanging upside down and submerged in the water. Under the illumination of the light, these strange stalactites reflected colorful light, making them magnificent and gorgeous.
, dazzling.
The underwater world is certainly beautiful, but as Chen Li said, this vast area has been completely submerged by the underground river, without even a space to surface for air.
Ning Xiaofan and others were equipped with sea submersible air tubes. According to the water depth data detected by the outpost staff, the deepest water area reached 50 meters. The entrance of the channel chosen by Ning Xiaofan was about 30 meters underwater, excluding the water flow.
Depending on the impact and water depth, the oxygen supply from the air cylinder can last for about an hour.
Then, Ning Xiaofan and his party must find an exit or a place to stay within an hour. The time cannot be precise yet, after all, there are two divers, Lao Wang and Xiao Shanzi, in the team.
Rookie, you have to have at least a few minutes left, otherwise the team will be completely wiped out.
Fortunately, Ning Xiaofan learned from Chen Li that although all the passages leading to the mining area were flooded by underground rivers, there were still some higher-lying places in the passages. It was not difficult to find a place to rest and breathe. Just wanted to
It is not easy to find the exit. According to Chen Li, it is best to find the exit before the air cylinder is exhausted.
Entering this water area, Ning Xiaofan did not dare to delay too much in the water. He roughly identified the direction and used the propeller to dive towards the pre-selected channel.
Sneaking all the way, soon, a rugged rock wall appeared in front of me. After swimming along the rock wall for a while, a dark cave came into view.
The diameter of the cave is about two meters. When Ning Xiaofan and his party arrived in front of the cave, they faintly felt a suction force coming from the entrance of the cave, and there seemed to be an undetectable flow of water flowing around them.
Ning Xiaofan felt a little happy when he felt the suction and water flow. The suction meant the direction of the water flow, which meant that the cave was not blocked, but was figured out.
Although I don’t know if this cave can lead to the mining area at present? But the passage chosen in advance should be the right one.
Everyone filed in with the help of propellers. The cave was deep and winding, and extremely dark. If you turned off the overhead lights, you would definitely be unable to see. Not only that, the water temperature in the cave was also much lower, and even the aquatic creatures were nowhere to be seen.
Traces.
After sneaking into this deep and dark water cave for more than half an hour, not only did this cave have many forks, it also gave people a feeling of being bottomless.
Moreover, Ning Xiaofan and others have already sneaked into unexplored areas. When a side road appears, Ning Xiaofan and others do not dare to change the route easily. You know, these side roads extend in all directions, and there are also side roads in the side roads, and God knows where they lead.
Where? I can only honestly believe that the main line of the cave is sneaking.
As time goes by, most of the air tubes carried by everyone have been consumed, and the exit still has not appeared. The cave still gives people a sense of no end. Not only that, too many forks in the cave lead to the dispersion of water flow.
The feeling of suction and water flow has almost disappeared.
According to the speed of the thruster, it is estimated that we have penetrated the cave for tens of miles. Did we go the wrong way? Or does this cave have no exit at all?
However, Ning Xiaofan knew in his heart that anxiety would not have any effect. Anxiety would only cause shortness of breath, which would rapidly increase the consumption rate of the air tank.
