Under normal circumstances, underwater sound will not travel more than two meters.
Fortunately, when Qiao An'an and the others went into the water, Zhang Qiang had installed waterproof walkie-talkies inside their helmets, so everyone could hear the sound.
And coincidentally, the insect that Qiao An'an threw out was within the range of the underwater searchlight.
This allowed everyone to see what the insect looked like.
Li Jianguo, who also loved reading tomb raiding novels, blurted out, "Corpse beetles!!!"
Chi Xiaoyu was speechless: "This is the FX lake worm, an early Cambrian marine organism. It belongs to a relatively primitive type of true arthropod. It is a mud-eating animal and does not pose a danger to humans."
For most people, after graduating from university, they have basically forgotten everything they learned in school. Chi Xiaoyu rambled on and on, but no one understood a word she said.
Fortunately, everyone understood that they posed no threat to them, so they didn't take the insects seriously. Just as everyone was about to continue searching for the underwater laboratory, a golden light suddenly rushed towards them from the direction where Qiao An'an threw the insects. It was so fast that before Li Jianguo could react, it had already knocked him to the bottom of the lake.
Li Jianguo fell flat on his face, spitting out a mouthful of blood: "What was that thing just now?"
The thing was moving too fast; all the people saw was a golden light that instantly illuminated the bottom of the lake, but they couldn't see what it was at all.
Because the thing knocked Li Jianguo over and then left quickly, the seabed fell into darkness again after it left. After seeing a moment of light, it went dark again, and everyone was still a little unaccustomed to it.
However, the thing seemed very interested in Qiao An'an and the others, and it rammed into them again.
The reason Qiao An'an and the others knew that the thing was coming again was because the area around them became bright again.
This thing was enormous and extremely fast underwater; a single impact would be equivalent to losing half their lives. The group quickly grabbed their weapons to prepare for a counterattack.
To their surprise, the thing didn't hit them; instead, it plunged headfirst into the mud.
Only then did everyone realize that this creature was at least 2 meters long and shaped like a large fish. It wasn't unusual for such a large fish to be found in the lake, but what was unusual was that it emitted a golden light. This light was so bright that it illuminated the scenery 20 to 30 meters below the seabed, making it even more effective than their underwater searchlights.
Shen Zhou quickly realized: "It seems to be eating the pile of insects from before, not attacking us."
Li Jianguo: "With its golden glow, it scares its prey away before it even gets close, so it can only eat insects that lie motionless in the mud."
Qiao An'an stared at the big fish, which was eating insects head down and constantly wagging its tail, for a while, then turned to Chi Xiaoyu and said, "It can glow!"
Chi Xiaoyu understood, took out a bow and arrow from her back, and shot it directly at the big fish's gills: "It will be a very good searchlight!"
The big fish was hit in the gill by the longsword and immediately thrashed about in pain. However, the arrows were barbed and attached to the small fish's quiver with extremely fine nanomaterials, so it couldn't break free for a while.
However, this fish was extremely large.
To prevent it from pulling away the bow and arrow along with the small fish in the pond, Chen Zhou, Fang Yuyang, and Li Jianguo worked together to lure the fish away. After a while, the fish finally stopped moving and let them pull it away.
With the fish providing illumination, they were able to locate the underwater base much faster, and soon they spotted a very large protrusion directly in front of them.
Although many of the protrusions were covered by mud and sand, the shape of a large submarine could still be vaguely seen.
That's it without a doubt.
They had originally planned to spend at least two hours finding the underwater submarine, and just in case, each of them carried two oxygen tanks down with them. They were surprised to find it so quickly, and everyone was excited, swimming rapidly toward the submarine's location.
But the goldfish, which was already half-dead, suddenly became agitated after seeing them swimming toward the submarine. It kept jumping up and down, and even tore off half of its gills to escape.
Qiao An'an looked at the half-eaten fish gill hanging from the arrow and said regretfully, "I was planning to eat boiled fish after we got ashore..."
Chi Xiaoyu was somewhat worried: "It seems very afraid of getting close to the submarine."
Li Jianguo: "I've seen many scientific research programs say that submarines release a kind of interference sound wave to avoid being hit by fish, which makes the fish panic and dare not approach."
Ye Jing: "You mean 'The Undersea Team'? I've seen that too, but isn't that an animated film?"
Li Jianguo emphasized: "An animated film that introduces the ocean."
Shen Zhou said to everyone, "Since the underwater laboratory can send a research submarine to attack us, it means they have already discovered our whereabouts. In any case, it's always better to be careful."
Everyone agreed that it was always better to be careful, and they cautiously moved toward the submarine's location. Once they got close, they discovered that the submarine was nearly ten meters wide, and their underwater searchlights couldn't even illuminate its exact length.
Shen Zhou and Fang Yuyang were born in Jun, so even if they had never piloted a submarine, they had learned about its functions from military programs. They told Qiao An'an that the submarine's entrance and exit were on the sail, and judging from the submarine's construction time, it was at least fifty years old and appeared to be abandoned.
In those days, the entrance was usually at the front of the submarine, and they had to find their way to the front of the submarine to find the entrance.
The group groped their way forward.
Ye Jing asked curiously, "How do people get in and out of a submarine when it's underwater? Won't it drown?"
Sunken Boat: "There are two levels of hatches. When exiting underwater, after entering the first hatch, there is a separate small compartment. At this time, there is no water. Close the hatch, fill it with water, and after the internal and external pressures are equal, open the second hatch to exit. When entering, first fill the small compartment with water, then open the door to enter the small compartment, then pressurize and drain the water from the small compartment, and then open the second door to enter the boat."
Yan Ling was listening to Chen Zhou and Ye Jing explain how the submarine enters and exits when she suddenly felt someone touch her calf. This made her very unhappy, and she asked somewhat angrily, "Who touched me?"
Everyone shook their heads. The visibility at the bottom of the lake was low, and Yan Ling didn't see the person who touched her.
Li Jianguo: "With your fierce appearance, who would want to touch you? Don't think that just because you were bumped by a fish underwater, someone touched you!"
She bumped into a fish and was touched by a person; how could she not tell the difference?
Yan Ling, who was initially just a little angry, was now furious: "Why are you so quick to say it was a fish that hit you? Could it be that you actually touched it? Are you deliberately trying to mislead us?!"
Li Jianguo was speechless: "Am I out of my mind to touch you?!"
Seeing that the two were about to start fighting underwater, Qiao An'an quickly stepped forward to break them up: "This is the bottom of the lake. Let's fight on the shore first, okay?"
Yan Ling had initially planned to let it go, but just as she was about to turn and leave, she was touched again. This time, she turned around and slapped him: "Are you sick in the head?!"
