Pacific Ocean Mariana Trench Deep in the depths, an eternal darkness was broken. Not by light, but by a low, soul-shaking hum.
A huge gap opened up in the seabed, revealing a metal structure that was definitely not a natural creation. Its surface was covered with ancient moss and sediment, and it was emitting a faint blue light at the moment.
Avengers Alliance's monitoring network is instantly overloaded.
"Fury, you'd better take a look at this."
The voices of Maria·Hill sounded in the command center, and the main screen showed a blurry image from the bottom of the sea - a huge, awakening behemoth.
Nick Fury narrowed his one eye. "It's the bottom of the sea again? Call Stark and Banner."
At the same time, Malibu Beach. Xiao Han frowned almost imperceptibly.
A low-frequency vibration came through the sea water. It didn't sound like a sound, but more like a pulse that acted directly on the neurons, making him feel... irritable.
It was like a fly buzzing in his ears, lingering. He turned over and pulled his sunglasses down, trying to ignore it.
The holographic image of Tony·Stark appears in Avengers Base, and the background is a crazy scrolling data stream.
"Okay, I'm not here for you this time, to bask in the sun." He said to Xiao Han who had just connected to the communication, "The energy characteristics are completely different.
More ancient, more... biological. Like some kind of alarm clock that had been dormant for millions of years and suddenly rang."
"Let's get to the point, Stark." Steve·Rogers is already fully dressed.
"The point is, this thing is at the bottom of Pacific Ocean, and it is turning the surrounding sea area into a restricted area for life. The energy field it emits causes all sea creatures that pass by to either die or undergo horrific mutations."
Bruce·Banner answered the call and called up several shocking pictures: twisted fish, an octopus that had expanded several times in size, and an ominous red light flashing in its eyes.
Natasha·Romanoff checked the equipment. "Target?"
"A huge biological structure, or... a living city?"
Tony projected the seabed scan, "We call it 'Leviathan'. It is absorbing geothermal energy and its scale is still expanding."
"S.H.I.E.L.D.'s plan?" Steve asked.
Fury took over. "Operation 'Abyss Strike'. Stark and Rhodes are responsible for aerial reconnaissance and fire suppression.
Romanoff and Barton led the commando team to try to infiltrate and install neutralization devices.
Doctor Banner and Vision are responsible for energy analysis and finding weaknesses. Rogers, you command the overall situation. Thor..."
"I heard the roar of the sea," Thor's voice came from the communication, accompanied by the sound of the wind, "I have already set off. This reminds me of Midgard Serpent in the Asgard record."
"Very good." Fury nodded, "Where is Doctor Strange?"
Wang's voice came in. "Sorcerer Supreme has been monitoring dimensional fluctuations at Sanctum Sanctorum. He said that the energy of this 'Leviathan' interfered with the structure of reality, and he must stay behind just in case."
The action started quickly. The battle armors of Stark and Rhodes broke through the clouds and rushed towards the target sea area. Under the sea, a S.H.I.E.L.D. submarine was silently heading towards Leviathan.
However, Leviathan's defense far exceeded expectations. Countless alienated sea creatures have now become its "white blood cells"
--Crazyly attack anyone who comes close. The giant squid whips Stark's battle armor with its reinforced tentacles, and the mutated shark hits the submarine with its sharp teeth that can bite through the alloy.
"Damn! There's no end to these things!" Rhodes shuttled through the intense firepower.
Underwater, the teams of Natasha and Clint encountered an even more terrifying sight:
Countless holes were opened on the surface of Leviathan, and guards who were half-mechanical and half-biological emerged from them. They were adapted to the high-pressure environment of the deep sea, and were fast and deadly.
"We can't get close to the core!" Natasha reported, while using a pulse gun to repel an incoming guard. "Its defense is active!"
Thor summoned lightning to bombard the outer shell of Leviathan, but most of the lightning energy was absorbed, leaving only scorch marks on the surface.
"Its shell is absorbing energy! Physical attacks are more effective!" He roared, swinging Mjolnir and smashing it hard, causing fragments to fly, but the wound was quickly covered by new tissue.
"It's learning!" Banner stared at the data in the laboratory, "It's analyzing our attack pattern! The physical resistance is improving!"
The battle has reached a stalemate, and Avengers is unable to move forward. The scale of Leviathan is still expanding, and the scope of influence of the energy field has spread to the coastlines of surrounding countries.
Just when Steve was considering ordering a temporary retreat, the situation suddenly changed.
Leviathan's core suddenly emits a strong pulse.
It was not an attack, but a scan. The pulse instantly passed through all Avengers, and finally... was locked in the direction of the distant Malibu.
"... It's looking for me." Xiao Han's voice suddenly sounded in the communication channel, with a hint of displeasure at being interrupted.
The pulse was like a cold needle, piercing him gently.
"What?" Tony was stunned.
"That noisy thing," Xiao Han's voice was cold, "It just... 'looked' at me."
As if to confirm his words, all activities of Leviathan suddenly stopped.
Then, all the light on its surface was extinguished for a short moment. When it lit up again, the frequency and intensity changed subtly, becoming more concentrated and... targeted.
It no longer paid attention to the harassing Avengers around it, but turned all its energy inward and began to condense something at an accelerated speed.
"The energy reading has soared!" Banner exclaimed, "It changed the mode! It is creating something! The target is... the energy signature of Xiao Han!"
A dark blue energy beam shot out from the top of Leviathan without warning. It was not shot at Avengers, nor at the sea surface.
Instead, it shoots straight out of the atmosphere, refracting a complex arc at a certain point, and the final target is accurately locked on Malibu!
Xiao Han was still lying on the beach chair, but raised his eyelids slightly.
The beam hit an invisible barrier a few meters in front of him, Oblivion silently, and the dissipated energy melted the surrounding sand into a piece of glass.
"Boring," he commented.
But Leviathan's attack did not stop. The second and third energy beams followed one after another, with the frequency getting faster and faster and the energy intensity getting higher and higher.
They still could not break through Xiao Han's defense, but the roar of the explosion and the flash of energy completely destroyed the tranquility around him.
The air around the beach chairs begins to distort from the heat.
Tony looked at the data transmission and was shocked. "It... it's not attacking him. It's analyzing! Every attack is collecting energy data from his defense!"
Inside Leviathan, in a chamber composed of biological tissue, a vague and ever-changing energy form is gradually condensing, and its core begins to flash with a red light similar to that in Xiao Han's eyes.
Xiao Han finally stood up slowly. He glanced at the sea level that was dyed strange colors by the energy aftermath, and then at the ruined beach beneath his feet.
His expression was calm, but there was a hint of extreme impatience deep in his eyes.
"Okay," he said calmly in the direction of Pacific Ocean, "You successfully caught my attention."
The next moment, he turned into a golden beam that tore through the sky and rushed straight towards the coordinates of Leviathan. His terrifying speed plowed a deep ravine on the sea surface.
Tony was stunned for a second, and then shouted in the communication channel, "Everyone, withdraw from the impact area! Immediately!"
Avengers moved away as fast as possible. As soon as they retreated far enough, they saw the golden light crashing into the core area of Leviathan like a spear of the gods without slowing down!
There was no huge explosion, only a dull, huge roar coming from the bottom of the deep sea.
Immediately afterwards, the entire sea surface suddenly arched upward, forming a huge hemispherical bubble, and then collapsed suddenly, triggering huge waves.
Under the sea surface, a huge hole penetrated the core of Leviathan, and the material on the edge was still vaporizing.
The unformed energy copy let out a silent wail and completely dissipated.
Xiao Han was suspended in the broken core of Leviathan, looking around. The alienated sea creatures and mechanical guards froze to death and fell off one after another as if the power supply had been cut off.
"Quiet." He said to himself.
However, under his Super Vision gaze, in the deepest part of Leviathan, some extremely ancient and scarred metal structures were exposed, engraved with symbols that were definitely not from earth civilization.
He raised his eyebrows slightly.
At this time, Tony's armor approached cautiously. "Is it solved? Is it dead?"
Xiao Han did not answer, his eyes still stayed on those symbols. After a moment, he turned to Tony.
"This thing was not made by the earth." He paused and added, "Besides, it may just be... a beacon."
After saying that, he ignored the shocked Tony, turned into golden light and disappeared, returning to his beach that needed to be renovated.
Deep in the trench, although the main body of Leviathan is silent, those ancient runes
But the last glimmer of light flickered in the darkness, as if sending the last message to the depths of the universe.
