Chapter 310 Buried Alive!
Zhang Yan took a deep breath.
Three thousand two hundred meters.
Upon reaching the target depth, the sea-devouring shark automatically switches to deep-sea cruising mode. All external lights are switched off, retaining only passive detection.
Darkness pressed in from all sides.
Complete and utter darkness.
Zhang Yan closed his eyes, allowing himself to adapt to perceiving the surrounding environment solely through sonar and system data.
It is seven kilometers from the entrance to the rift valley.
He went through the plan one last time in his mind.
Two torpedoes, directional detonation, sealed off the rift valley.
Rush into the basin at full speed.
The Black Scorpion was released, and the two of them attacked the one guarding the house, suppressing it.
Mining fragments.
Evacuate.
Three to five minutes.
The phone vibrated one last time.
Nie Qingcheng: "The signal's about to drop. Goodnight. Come back."
Zhang Yan replied with two words.
"wait for me."
The notification flashed briefly, and then the notification bar turned gray.
The world above the sea has ended.
From that moment on, at a depth of 3,200 meters, only he and the sea-devouring shark remained in the ocean.
Two monsters were waiting for him in the darkness ahead.
Zhang Yan opened his eyes.
His finger gripped the torpedo launch trigger.
It is three kilometers from the entrance to the rift valley.
Zhang Yan did not slow down.
The distance of three kilometers takes less than five minutes at a speed of twenty knots.
On the sonar spectrum, the A+ signal, guarding the bottom of the rift, remains silent. It lies at the narrowest point of the passage, like a stone.
If it weren't for the system's continuously flashing red indicator, the passive sonar wouldn't be able to distinguish between living creatures and terrain.
It was hidden very well.
Their ability to disguise themselves is ridiculously high.
Zhang Yan narrowed his eyes.
An A+ rank monster has even gone this far with its disguise. If it were to go all out, its aggression would be even more terrifying.
It is 1.5 kilometers from the entrance to the rift valley.
He began to calculate.
The rock mass of the rift valley sidewalls is metamorphic basalt with a density of approximately 3.0 g/cm³. The sidewalls range in thickness from eleven meters at their thinnest point to over thirty meters at their thickest.
The directional explosive yield of two supercavitating torpedoes is enough to tear apart the thinnest rock wall and trigger a chain reaction collapse—provided that they hit the thinnest points on both sides at the same time, causing the debris to come together from both sides.
The error must not exceed two meters.
Underwater torpedoes are less accurate than those launched from the surface due to ocean currents.
However, if the distance is close enough, this deviation can be reduced to within one meter.
It is 800 meters from the entrance to the rift valley.
Zhang Yan's fingers fine-tuned the flight parameters of the two torpedoes on the control panel.
Torpedo No. 1 – 18 degrees to the upper right, struck the second weakest point on the right side wall of the rift valley.
Torpedo No. 2 – 22 degrees to the lower left – struck the first weakest point on the left side wall of the rift valley.
The detonation interval between the two torpedoes was set to 0.3 seconds.
First right, then left. Let the rubble on the right fall first to block the target's right flank retreat, then let the left side collapse and close to seal off the entire passage.
500 meters.
New changes have occurred in the sono.
The A+ level guard moved.
It didn't move much; it simply changed from a prone position to a crouching one. It sensed something.
But no attack has been launched yet.
Three hundred meters.
Zhang Yan could see the outline of the rift valley—not with his eyes, but with the three-dimensional outline drawn by the sonar echoes.
A huge chasm, forty meters wide and more than seventy meters high, with the rock walls on both sides as if cleaved by an axe.
At the bottom of the rift valley, a blurry biosignal clung tightly to the rock face.
The system automatically marked its outline.
It resembles a flat, tailless giant ray. Its body is over thirty meters wide, almost filling the rift valley.
Its back is covered with dense thorns—each thorn is over two meters long.
Two hundred meters.
Zhang Yan pressed the trigger.
The two supercavitating torpedoes detached from their launch tubes almost simultaneously, leaving two long, thin trails of bubbles in the water, and hurtled toward the rock walls on either side of the rift valley at a speed of over two hundred knots.
0.7 seconds later.
The first muffled thud.
A huge low-frequency vibration traveled through the seawater, causing the sea-devouring shark's shell to vibrate violently.
Zhang Yan was jolted in his seat.
The right side wall of the rift valley exploded, and the metamorphic basalt shattered into countless tons of gravel under the high temperature and pressure of the explosion, carrying astonishing kinetic energy as it crashed into the bottom of the rift valley.
0.3 seconds later.
A second muffled thud.
The left side wall also collapsed.
In the sonar footage, the entire rift valley passage was swallowed up by the debris flow that converged from both sides within two seconds.
Thousands of tons of rocks cascaded down from a height of seventy meters, burying the A+ class giant ray and the spot where it was crouching into a pile of rubble.
On the sonar spectrum, the A+ grade signal jerked violently for a moment—like a giant ray struggling for a split second before being buried alive.
The signal was then covered by layers of rock, attenuating into a blurry mass of noise.
Zhang Yan stared intently at the swirling noise.
It did not disappear.
It is still alive.
An A+ level of vitality cannot be killed by rubble.
But being trapped under thousands of tons of rock, it will take time to dig it out.
How long?
The system popped up an estimate: "Based on the target's size and estimated strength, it is estimated that it will take 240 to 330 seconds to break through the rock blockade."
Four to five and a half minutes.
enough.
Zhang Yan pushed the gear lever all the way to the bottom, aiming for full speed.
Like a black arrow, the sea-devouring shark swept across the collapsed rift valley, over the top of the rubble, and plunged into the open basin on the other side of the rift valley.
On the system panel, the timer started counting down.
330 seconds.
The outline of the basin's sonar unfolded before Zhang Yan.
An irregular circular depression about 300 meters in diameter, with a flat bottom and covered with thick deep-sea sediment.
The fragment is located in the very center of the basin, eight meters below the sedimentary layer.
But seventy meters above the debris, a second A+ grade red marker is moving rapidly.
It heard an explosion.
It is turning towards the direction of the sea-devouring shark.
Zhang Yan pressed the storage space release button with his right index finger.
The colossal silhouette of the Black Scorpion materialized out of thin air sixty meters to the right of the Mechanical Shark.
In the deep sea, the tens of tons of mechanical giant scorpion's exoskeleton instantly withstood the enormous pressure of a water depth of 3,200 meters, and a series of sharp metallic stress sounds emanated from its joints.
But it held on.
Zhang Yan split off half of his consciousness and connected it to Xuanxie's control port.
"Directly ahead, 120 meters away, 70 meters high. Intercept."
The black scorpion spread its six segments in the water, its thrusters fully activated, dragging its heavy body diagonally upwards.
Its mission is not to kill the target.
It's about blocking it.
310 seconds.
On the sonar, the complete outline of the second A+ grade was analyzed by the system.
It wasn't a ray, nor was it any form Zhang Yan had ever seen before.
It resembles a deep-sea eel without scales, but its body is covered with layers of dark red soft tissue that curl outwards, as if a new layer of something that doesn't belong to marine life has grown after the skin has been peeled off.
It is over forty meters long.
The head—if you can call that four-lobed front end the head—was opening towards the sea-devouring shark.
The inner side of the four "petals" is densely covered with inward-curving horny teeth.
A giant live meat grinder.
