Qin Fengyi first tested the depth of the water with a stone, the surface of this pond is only 3 meters square, the edge of the pond is a shallow water area, and if you continue to go deeper into it, the water in the deep water area is extremely deep, and the stones thrown to the test splash a lot of water.

"The water is so deep, it's like the seepage hole last time. Lin Qingxue shrunk her neck, looking at the dark and deep puddle was particularly terrifying, especially the bright light on the water.

"I suspect that this place seems to be connected to our well. Qin Fengyi took out the piece of foam from his backpack and was picking at it with his fingernails, separating out many foam particles.

"Impossible, the two places are so far apart, how can they be connected?" Han Xue Ning frowned, estimating the distance between the two places, which were at least several miles apart.

"You can't ignore the capacity of the underground waters, it's like an underground river, maybe there's an underground river underneath the island. Qin Fengyi wrapped the foam particles with bush leaves, and a stone was also stuffed inside.

"What is this guy going to do?" Lin Qingxue couldn't understand Qin Fengyi's operation, and was pushing Han Xuening, who was frowning and contemplative, "Teacher Han, do you understand?"

"It was as if he was going to get the foam particles deep into the pool. Han Xue Ning rolled her big eyes.

"Puff ......"

The stones wrapped in leaves are very heavy, driving the leaves to sink obliquely towards the bottom of the water, and the stones thrown by Qin Fengyi are quite tricky, because the water on the side of this waterhole is very deep, and there seems to be a waterway, and the leaves fall towards the underground water road under the gravity of the stones.

It didn't take long for strings of foam particles to float up from the black pool, and the foam particles wrapped in leaves were not strong, but soon loosened, and the buoyant foam lost the wrapping of the leaves and floated to the surface.

There are only a few foam particles floating above the water, and the rest should flow down the underground water, which is very high, and according to the practice of flowing water downward, it may flow down with the water.

They made a lot of foam particles and carried them to the underground water with leaves and stones, and everyone was ready to leave here to see what they had gained from the shipwreck.

Qin Fengyi...... Are you worried that we have these monsters in our well?" Lin Qingxue followed Qin Fengyi's side, staring at his more handsome face.

"Well, but our well is relatively safe, the water is at least 5 meters from the wellhead, and even if there are these guys, they can't climb up. Qin Fengyi recalled what he saw in the well in the morning, and was a little sad.

In case of...... What to do if the water table skyrockets?

If the water from the well overflows, the guys can climb out unimpeded, so that they can see what they really look like and taste the salamander.

The salamander is supposed to be the same species as the salamander, but it is only very large on the island, estimated to be 2 meters long.

......

After burying the woman's body, everyone went up to the raft and paddled through the shallow sea transition of more than 300 meters, where the water was about 2-4 meters, and saw crabs, conchs and larger marine fish on the raft, and then came to the coral reef.

"The sea is so rich!" Lin Qingxue and Han Xuening were already dazzled, the coral reef had white-red corals, and there were many marine fish, red, blue, and yellow...... Numerous.

Of course, there are sharks too!

The largest number of them are hammerhead sharks, which feed on coral reefs and chase all sorts of small fish.

"There are sharks...... Lin Qingxue looked at the bottom of the water worriedly, grabbed Qin Fengyi's arm with her little hand, and pleaded slightly, "Don't go down, it's dangerous down there." ”

"It's okay, hammerhead sharks don't eat people, and I go down with Yayale, there will be no danger!" Qin Fengyi gently patted the back of Lin Qingxue's hand, Xiao Nizi's little hands were smooth and soft.

Looking at the bottom of the sea through the sea, the current light is quite good, and you can roughly see the shipwreck on the bottom of the sea, and from above, the water depth is about 10 meters, and the shipwreck sinks in front of the coral reef.

"Okay, you guys wait for me here!" Qin Fengyi didn't go into the water with a bow and arrow, only a Miao knife and a dagger, because the resistance was too great, he couldn't shoot an arrow in the sea at all, "The bow and arrow are left for you, if a shark dares to come out of the water to attack you, shoot it with an arrow and stab it with a spear!"

"Got it, we'll take care of ourselves, and so are you, if you can't hold your breath, hurry up and get your breath. Lin Qingxue was a little reluctant, although the distance was only more than ten meters, but the water was not as good as the land, and it might be dangerous for humans to be in the water for a long time.

"Good!"

Qin Fengyi didn't say much, he spit twice in the diving goggles in advance, and smeared the lenses with his fingers, so that there would be no fog when diving, and then Yayale went into the water, Qin Fengyi followed, "Wangcai, protect them!"

Wangcai is very dragged on land, and there is almost no combat power in the water, and with it, the girls will not be in much danger.

Holding the tail of Yayale diving, Qin Fengyi did not turn on the shark's breath at first, he wanted to try how long his limit was, when he was a child, he held his breath in the countryside to swim, among many friends, he held his breath for a long time, the limit was 2 minutes, but with the gradual dive, you can clearly feel the change in water pressure and water temperature.

At first, the water temperature is about 20 degrees Celsius, which is a little cool, but it is acceptable, but as you dive down to the reef, the water temperature drops sharply, and you can feel the pain like a pinprick and the chill engulfs.

Under the action of water pressure, there was a feeling of being squeezed all over his body, and he was feeling an invisible pressure in his chest, Qin Fengyi kept counting for a few seconds, about 30 seconds, and he couldn't hold it anymore.

At the same time, Qin Fengyi also dived about 12 meters, and the arrival of him and Yayale disturbed many swimming fish, the small fish scattered and fled, the sea anemones in the coral reef also put away their tentacles, and the polyps hid.

In the coral reef, there are many lobsters, which belong to no man's land, and the lobsters have not been caught in a big way, and at the first time, Qin Fengyi found several lobsters, among which several larger ones are hiding in the rock caves under the coral reef.

Catch a few lobsters first, and go up to breathe by the way!

Qin Fengyi didn't use the Miao knife in his hand, but directly reached out of his hand, outside the coral reef cave, there were two long tentacles, which were the marks of the lobster, and it didn't know that it had been exposed.

"Whoa~!"

There was a burst of turbid sand, Qin Fengyi grabbed the lobster who was struggling with his life, this guy was very big, as much as 6 catties.

The first time I caught a lobster in the sea, I had a lot of fun hunting!

Lacking enough breath holding, Qin Fengyi motioned for Yayale to rise, and at the same time had to send the lobster back to the raft.

Grabbing Ya Le's tail and floating, he saw through the bottom of the sea that the sea surface was a piece of fragmented light, and the surging waves cut the sunlight, just when he was about to emerge from the water, Qin Fengyi seemed to see something, and immediately signaled Ya Ya Le to stop!

"Tooth tooth...... Gurgling ......"
