Start with push-ups to gain experience

A deep, rumbling sound erupted from the depths of the ocean.

It sounded as if bursts of thunder were exploding in the darkness.

The seawater in the abyss gradually began to rotate around the city ruins.

At first, it was just a slightly sluggish surge.

But after only a few breaths, the water flow turned into a rapid eddy.

Tens of thousands of powerful undercurrents collided and intertwined, carrying an overwhelming momentum as they surged towards the sky above the underwater city.

In the blink of an eye, a giant vortex, a hundred times larger than the crater, appeared out of nowhere, almost completely engulfing all the ruins.

The vortex was pitch black, like a giant maw that could devour the sky and the earth, releasing an incomparably powerful force of nature.

Seawater was continuously drawn upwards, forming surging waves in mid-air.

Amidst the turbulent currents, Fang Cheng's feet seemed rooted to the ground, firmly planted in a horse stance.

All the muscles in his body tensed up instantly, and his blood and qi surged, making a sound like a raging river.

With his strong physique and composure, he withstood the pulling force that was enough to crush an armored vehicle.

buzzing-

It seemed to be responding to the massive vortex overhead.

Even the towering, round stone pillars surrounding the ancient city ruins began to move.

The ancient patterns, which had been blurred and indistinct, suddenly lit up all at once, faintly radiating a deep blue light.

"Has the formation been activated?"

Fang Cheng's eyes narrowed slightly, and a look of surprise appeared on his face.

Meanwhile, the earth's crust continues to tremble violently.

Seabed sediment and volcanic ash, accumulated over millions of years, were violently ripped apart by an invisible force.

The mud and sand mixed with the water flow, turning into turbid waterspouts that shot straight into the sky.

A massive wall of water rose from the ground, surging upwards and forming a dramatic flow resembling countless rivers flowing into the sea.

This spectacular sight is like a giant dragon lurking deep in the trench opening its mouth, swallowing the entire sea like a whale sucking in water.

After tens of thousands of tons of seawater were pumped away, a vast vacuum zone was suddenly torn open at the bottom of the 10,000-meter-deep abyss.

The thick layer of mud that had covered the building ruins was swept away, revealing the clean, smooth white bricks underneath.

Fang Cheng felt a sudden lightness throughout his body, as the immense water pressure, as heavy as a mountain, vanished completely.

He immediately withdrew his domain, extinguished the golden flames on his body, straightened up, and looked up at the sky.

A magnificent and awe-inspiring scene unfolds before our eyes.

At this moment, he felt as if he were standing in the eye of a storm.

Above their heads, hundreds of millions of tons of dark seawater were lifted up by an invisible array, like a thick, black thundercloud.

The surrounding waters squeezed and rubbed against each other, producing a deafening roar.

That pitch-black "ocean sky" hung overhead.

It could transform into a massive, earth-shattering downpour at any moment, crashing down once more.

Just as Fang Cheng was secretly on guard.

The remains of all the giant beasts scattered in the streets and squares seemed to have been summoned by some ancient will.

The azure light on the surface of the bones burst forth in an instant, reaching its peak brightness.

Countless ribbon-like blue particle trails rose from the skeletons, rapidly intertwining and overlapping above the city ruins.

In the blink of an eye, these particles transformed into a massive blue light barrier covering an area of ​​several miles.

The barrier hummed and shaped like an inverted bowl, forcibly isolating the dark abyss above and the terrifying water pressure.

Before Fang Cheng could recover from this earth-shattering change...

The focal point of space in the center of the crater behind him was also expanding rapidly.

boom!
A blue beam of light, tens of meters in diameter, shot into the sky from the vortex at the bottom of the crater.

The beam of light, carrying immense pressure, pierced straight through the city and plunged into the center of the "black storm" that enveloped the entire ruins.

The colossal vortex that blots out the sun in the sky and the tiny focal point leading to another world inside the crater, under the guidance of the blue beam of light, create a strange resonance.

The violent pressure from above and the spatial suction from below pull at each other and cancel each other out, ultimately forming a strange balance.

The light barrier, which had been trembling violently, quickly stabilized under the soothing force of this balancing power.

A soft yet indestructible shimmer flows across its surface, completely eliminating the risk of seawater collapse.

The surroundings became completely quiet.

Fang Cheng slowly exhaled a long breath, his gaze sweeping over his surroundings.

Without the cover of seawater and the concealment of volcanic ash, the original appearance of the entire city is clearly revealed.

The wide, brick-paved streets crisscrossed the area and appeared spotless.

The dilapidated palace buildings are scattered in a well-organized manner, revealing ancient and mysterious stone sculptures.

The towering stone pillars stand in rows, appearing solemn and majestic under the blue light.

In an instant, time seemed to flow backward.

Fang Cheng stepped on the hard stone bricks, breathing in the thin air that seemed to have sprung up out of nowhere within the formation.

Looking at the city before him, now completely cleansed, he felt as if he had traveled through millions of years, witnessing firsthand the glorious past of this ancient city before it sank into the abyss.

Fang Cheng strode along the main road, heading towards the heart of the city.

The buildings along the way are laid out in a very orderly and well-organized manner.

Even after the passage of time, the open central square, the circular park, and the various functional zones can still be clearly distinguished.

However, as the formation was fully completed, the ancient remains scattered on the ground also changed.

Perhaps it's because the energy contained within was forcibly extracted by the formation.

The luster on the surface of the bone was visibly fading, eventually turning into a grayish-white ordinary fossil.

Fang Cheng stopped, bent down, picked up a fragment of animal bone, and carefully sensed it in his palm.

The remaining radiant energy has almost completely disappeared, like a sponge that has been completely drained of water.

"Pity……"

Fang Cheng shook his head and casually tossed aside the worthless bone.

After going through so much trouble to dive to a depth of 10,000 meters, and just when they were about to have a bountiful harvest, it all turned into nourishment by this protective formation.

However, he quickly adjusted his mindset and comforted himself.

At worst, I can wait until the true energy in my dantian is fully replenished and I am ready before entering the other world through the passage in the crater.

Since these skeletons originated from there, there must be even more abundant "treasures" at the other end of the passage, or even living ancient behemoths.

Thinking of this, Fang Cheng straightened up and raised his head.

His gaze swept across the street to the blue light shield in mid-air that blocked the dark, oppressive wall of water.

Just as he was about to turn back to the crater to investigate the changes below, he caught a glimpse of something unusual out of the corner of his eye.

A silver reflection suddenly appeared in the ruins of a side hall not far ahead.

The light was very faint, flickering intermittently through the gaps in the collapsed building.

But against the backdrop of the gray-white fossils scattered on the ground and the pale blue ambient light, this silvery glint stood out conspicuously.

It was as if they were deliberately trying to lure him there.

Fang Cheng's eyes narrowed, and he immediately strode over.

He grabbed a broken stone pillar weighing several tons with one hand, and with a sudden burst of strength, easily flipped it aside. The objects buried underneath were now fully revealed.

It was a simple, silver key, lying quietly in the crack of the stone bricks.

The surface shows no signs of rust and is even clearly carved with intricate patterns identical to those on the giant stone pillar.

Fang Cheng bent down, picked it up, and examined it in his palm.

What is this?

He brought the key close to his eyes.

The silver metallic texture carries a cool sensation that penetrates directly to the palm.

With the help of the dim light from all around, you can see that the texture on the surface of the key is extremely fine.

It wasn't a simple decorative pattern, but rather a collection of countless tiny incantations pieced together end to end.

These lines are like an extremely complex code, layer upon layer, intertwined and entangled.

It seems that every engraving and every turn in the line hides secrets unknown to mortals.

Fang Cheng raised his left index finger and slowly stroked it along the texture of the key handle.

The moment his fingertips touched those raised and recessed marks, a subtle ripple stirred deep within his mind.

The "Omniscient Language" talent is passively triggered, and countless sparks of inspiration flash and recombine in consciousness.

Fang Cheng's pupils suddenly contracted, and his eyes flashed with an unusually bright light.

In just two or three breaths, he fully grasped the meaning of these complex incantations.

This is a key that can open the "ultimate door," containing the extraordinary power to traverse space.

As for what exactly the so-called "ultimate gate" is and where it leads?

The incantation did not provide a definite explanation, and Fang Cheng had no way of knowing it.

However, he fully grasped the mechanism of use of this item from the feedback.

The method is very simple.

Users need to select a coordinate point within their field of vision.

He then imprinted this coordinate into both his consciousness and the key, thereby constructing a special spiritual link.

After that, no matter how far away you are, as long as you recall that coordinate in your mind and silently recite the incantation engraved on the key, you can summon a spatial gate in the void.

Holding the key, I opened the door, stepped through it, and instantly arrived at my destination.

At the end of the incantation, its true name is left: "Silver Spoon".

"Spatial jump ability... this is practically a divine artifact!"

Fang Cheng gripped the key tightly, his breathing involuntarily quickening, and his heart pounded powerfully in his chest.

The regret that had just arisen because the ancient remains had their energy drained by the formation vanished at this moment.

Compared to those bone fossils that are used up and then discarded, this silver key is clearly the most important treasure in this underwater ancient city.

With it, the constraints imposed by distance and space will be completely broken.

Speaking of which, Fang Cheng had always envied Cheng Jiashu, envying his ability to jump through space and his free and easy manner, coming and going without a trace.

Now that I have mastered similar abilities through this key, I no longer need to envy others.

Fang Cheng closed his eyes, slowly exhaled a long breath, forcibly suppressing his excitement and bringing his emotions back to rationality.

"Descriptions alone are not enough; we have to actually try it out."

He raised his head, his gaze sweeping over most of the ancient city ruins and landing on the crater a kilometer away.

Using the soft light streaming down from the dome, he spotted a protruding volcanic rock that resembled a broken sword.

With his gaze focused on the rock, Fang Cheng began to mobilize his mental energy.

He sketched out the outline of the rocks and the details of the surrounding environment in his mind.

At the same time, he slowly channeled this spiritual intent into the array of the silver key through his palm.

drop--

A faint echo seemed to resound deep within his consciousness, and a hidden mental link was instantly established.

Fang Cheng raised his right hand, which was holding the key, and muttered a strange incantation under his breath.

As the silver key emitted an incomparably dazzling light, the air in front of it suddenly began to distort.

Then, a thin, elongated spatial rift appeared out of thin air.

Immediately afterwards, the gap, like an eye awakening, rapidly expanded from the center to both sides.

It eventually opened into a door about two meters high, emitting a faint blue light.

Fang Cheng took a small step forward, aligned the silver key with the round hole in the center of the light gate, and twisted his wrist to the right.

Click.

A crisp click of the mechanism engaging rang out, and the door slowly opened.

As the blue light surged, the view behind the door suddenly opened up, clearly revealing the volcanic rock shaped like a broken sword.

Without the slightest hesitation, Fang Cheng stepped into the portal of light.

The surrounding scenery was instantly stretched and distorted, and the feeling of weightlessness brought about by the spatial transformation was fleeting.

When Fang Cheng's other foot touched the ground again, he felt the rough texture of volcanic rock beneath his feet.

He turned his head to look.

The ruins of the side hall, a kilometer away, were now far behind.

"It worked!"

Fang Cheng looked at the silver key in his hand, a satisfied smile curving his lips.

This space-traveling verification has thoroughly confirmed the incredible power of this key.

Composing himself, he lowered his head and turned his gaze back to the bottom of the crater.

The situation below is completely different from before the formation was activated.

The massive blue beam of light, tens of meters thick, resembled a towering structure, completely covering the distorted area that had previously resembled a shattered mirror.

Without the influx of seawater, the attraction of that focal point becomes negligible.

It was as if all the spatial pulling force had been guided by this beam of light into the giant vortex above the dome.

Fang Cheng stared at the surging blue particles within the pillar of light, slowly raising the silver key in his hand, his gaze flickering uncertainly.

Now that I possess this wondrous object that allows me to traverse space, I can try many things that I never dared to imagine before.

Should we take advantage of the array being activated and the spatial passage being stable, and go directly to the other side of the world for a look?
Even if there is some danger lurking at the other end of the passage, as long as you react quickly enough, you can use the Silver Key to reopen the door and immediately return to this world.

The thought lingered in Fang Cheng's mind for a few seconds, but he ultimately shook his head.

"It's not the right time yet."

The test just now was only a short-distance teleportation within one kilometer.

And traverse the void of the universe to reach another distant world, even one that is not in the same dimension.

The amount of spatial energy load it will bear during this period is completely unknown, as the two are fundamentally different.

Moreover, in order to withstand the pressure of water thousands of meters deep, nearly half of the remaining true energy in his body had already been consumed.

We must wait until the true qi in the dantian is replenished and the condition returns to its peak before making any plans.

Acting prudently allows for a higher margin of error.

To avoid any unforeseen circumstances in the other world where even the key becomes ineffective, leaving them completely trapped and unable to return. (End of Chapter)
