"See?" The tank pointed in one direction, and that place was behind the waterfall. Andy peeked there with the telescope in his hand, and it was a bit difficult to tell what was there through the huge splash of the waterfall, if according to the tank brain, his eyes could tell that there seemed to be some traces of man-made structures in the gap between the huge waterfall and the mountain wall behind it.

He looked and looked, and after his eyes were sour, he finally caught some signs of reinforced concrete, and it seemed that there was some human element in the environment here.

"There seems to be a road there?" Tank Brain nodded.

"It's not going to be enclosed, if the water above is coming from a pipe, then it's definitely an artificial landscaping, and in that case there will inevitably be maintenance spaces and maintenance passages, whether for human employees or robots." String searched left and right and found a vague path among the plants, so the three of them followed the path towards the back of the waterfall, but when they arrived, they were dumbfounded.

There was also severe damage, with the earthquake filling the mountain wall behind it with cracks and shattering the artificially built corridor.

"How is this going to pass?" Andy looked speechlessly at the waterfall above, the endless water pouring down from the cliff, and couldn't believe how the people who built the nursery had artificially realized this attraction in the first place..... After a while, he came up with a plan.

"Look over there, there should be enough for us to get into." She pointed to a crack deep behind the waterfall, wide enough for the few of them to use as an entrance when they got closer.

But this leads to a new question, how do you get close to this place with all the deep water and a waterfall next to it?

.............. At this moment, the group returned to the shore where they had just been, and finally found a solution, which was a small dark red boat that remained here in a hidden mooring on the side of the lake.

It's rusty, but miraculously it's still floating on the water, and it's big enough to hold three people.

"Are you sure this is okay?" The mechanical arm of the cylinder brain grabbed a piece of rusty iron with a force.

"If we sink halfway, all three of us will be doomed.... Who knows how deep it is underneath? Andy forcibly pushes him onto the boat and then asks if String can swim, which he answers in the affirmative.

"Don't be afraid, I'll throw you out if the ship sinks!" So the three of them boarded the boat, and Andy began to row with two old oars, he was still a little confident in his swimming skills, even if the boat sank, as long as he was closer, he still had the confidence to swim past.

Crash..... Crash..... The tank was frightened and shrunk in the middle of the boat, not daring to move, with its weight and mobility, if it fell into the water, it would be miserable, and maybe it would never have a chance to return to the shore.

The movement of the ship quickly attracted the huge snakes, who quickly approached underwater, surging towards it like a black countercurrent.

The guys were bigger than the ones downstream, and they slammed into the boat so ferociously that it swayed from side to side, and a few of them rushed straight out of the water and opened their jaws towards Andy.

Before he could pull out his pistol, Andy slapped the snake away with the oar in his hand, and the force was too great to cause the oar to deform a little.

The strings and the tank brain also launched a counterattack against the water, and the witch snake continued to roll and retreat. The group finally came to the waterfall, the torrent that fell into the lake made the snakes retreat, and then they went around the edge to the back of the waterfall, which was dark and damp, and the majestic sound of the water echoed on the mountain wall, causing their hearing to be reduced to 0, and there was no point in communicating verbally.

But the noise aside, the waters are much calmer than outside, after all, most of the water flowing out of the lake is directly from the outside of the waterfall, and the back of the waterfall forms a large backwater pool.

There are huge cracks in the wall of the mountain next to it, and some places have exposed the space inside, which has obviously been severely remodeled, and it is likely that the interior of the mountain has been completely hollowed out.

As you can see, the path that could have been accessed from the shore outside has been destroyed by the earthquake, revealing steel bars that roll up like bones.

With Andy's efforts to shake, the three of them were about to reach the thickest of cracks, through which they could even see some of the rotten cabinets and broken doors inside.

Looking at the traces of human activity, the fear of deep water in his heart was slightly reduced, and while complaining about the strange taste of the builders here, he came to the side of the boat and glanced at the water, who would have thought that this look directly saw him in the psychological shadow.

Deep beneath this tranquil pool, with the help of his electronic eye, which was more sensitive than the human eye, he could see one coiled into one under the water

The behemoth of the "volume". The width of the thing was even much wider than the boat, and the length was even more difficult to assess, as only a part of it could be seen.

The tank collapsed into the boat with a thud, and because of the loud noise of the waterfall, String and Andy couldn't figure out what was wrong with this guy.

“.... You...... Hurry .....up" grabbed Andy, the manipulator kept pointing underwater, Andy couldn't hear what he was talking about at all, and turned on the light of the beep-boy for some reason, and then he was also startled.

A few meters underwater, there is a large unidentified monster like a black dragon. String didn't see anything underwater, but seeing the panicked looks of the two of them, he knew that something was probably wrong, so he quickly ran to Andy's side to help him row together, and even the cylinder brain inserted his mechanical arm into the water and spun wildly, trying to get closer to their destination and not continue to float on this dangerous water.

But it was too late, a black unidentified object came out of the water and slapped at the boat, Andy didn't have time to think about it, grabbed the string with one hand and threw her towards the chasm, and then threw it with both hands in the same way as he threw the shot put.

As soon as he had done all this, the tail casually slapped the boat into pieces, and Yu Wei knocked Andy away, and he rolled directly into the curtain of water falling from the waterfall.

"Grunt....." Andy, who was spinning in the sky, was stunned by the water flow above, and couldn't even tell the difference between the south, east, west, north, west, left and right, all directions were full of chaotic splashes and bubbles, and his body was full of pain.

Fortunately, he had a high level of stamina, recovered from the chaos, held his breath, and used the positioning of the Pip-Boy to find his way back in the water, and struggled to move forward in the chaotic underwater undercurrent.

But it didn't take long for an indescribable pain in his back that caused him to choke on a large mouthful of water on the spot.

A witch snake spotted him, swam over and bit him, clinging to it like a sucker, and the dense fangs in its mouth were all firmly bitten.

Not only did it instantly start sucking a lot of blood, but it was also tearing at the flesh, because the most comfortable space for the witch snake was the abdominal cavity of its prey.

The beep-boy sounded the alarm. [Warning: You are losing severe blood, and your health is fixed to drop every second] [Warning: You are running out of oxygen, the countdown is 15s, and the countdown will start to deduct health quickly after the countdown] Andy didn't have time to look at that, he gritted his teeth and swam towards the water, and finally exposed his head to the surface of the water to breathe air.

"Woo...! Poof...."After a few quick breaths of misty air, Andy immediately looked for a direction away from the water, and he saw that the Cylinder Chord seemed to be yelling at him not far away, but because of the waterfall, he could only see them open their mouths, but he couldn't tell what they were saying.

A flash of lightning struck, briefly illuminating the dimly lit space. Andy saw a huge snake staring at him underwater, its head about the size of a boat was densely packed with eyes, and a random whisker on the side of its mouth was almost as big as the snake he was biting, and the thing that smashed the boat just now was its huge flat black tail.

Its ugly face was looking at Andy at the moment, slowly opening its mouth, which was numbly numb with teeth, and its mouth was like a crusher leading to a black hole.

Andy froze in place, feeling such suffocating despair for the first time.

"Plop! A splash of water burst into Andy's face, waking him up from his fear. He jerked his head to see String leap out of the water from the side of the rift.
