However, the turning point in the story begins with Cheng Xu.

When Xi Xi received Cheng Xu's televised connection, she was doing aerobic training on the treadmill.

"Sis! My winter coat... seems wrong!" Cheng Xu's voice changed, and his breathing became rapid.

"There's something wrong here!" Liu Yunyan's voice also came from the light screen. She was the one who helped Cheng Li and the other draw the teleportation talisman and was the first to notice the anomaly.

Li Jinshao shouted sharply from the side, "Get out of here immediately! We can't go any further!"

Xi Xi's heart tightened, and she rushed to the window. She saw a sticky, heavy feeling quietly enveloping the steel car body. The seawater outside the porthole was no longer clear and transparent, but instead murky and dark like spoiled wine, making it suffocating.

"Turn around!" She didn't have time to think and immediately ordered the puppet manatee.

The manatee seemed unaffected, continuing to gallop at the same speed until it heard its owner's command, at which point it turned and circled halfway around.

Due to inertia, the RV tilted sharply, and Chu Zhiqin almost lost her balance, but was fortunately supported by Xi Zhongcang.

Xi Xi arrived at the Cheng family's RV through the teleportation array. She saw that Cheng Xu's specially made cold-proof clothing was hissing, with fine white foam rising and disappearing quietly, like a group of invisible termites frantically gnawing at it.

Cheng's mother frantically pulled at her son's coat, revealing scattered corrosion marks on the removed winter clothing. Xi Xi reminded her not to touch it, so Cheng's mother hardened her heart and threw the coat into a nearby metal basin.

"What on earth is going on?!" Mr. Cheng was busy with the transaction when he was abruptly interrupted.

Immediately afterwards, a strange crackling sound came from beneath everyone's feet, as if ice was breaking, dense and despairing.

Xi Xi suddenly looked up and saw a thin crack, as fine as a hair, stubbornly extending downwards from the corner panel of the Cheng family's RV.

The icy seawater, like the cold sweat of a dying man, hesitated before seeping out the first drop, then quickly forming a continuous line, drip, drip...

"Quick! Cleansing talisman and heating talisman!" Xi Xi seemed to have seen through the situation, her voice piercing through the suffocating panic, clear and decisive.

Leaks in underwater compartments are the most dangerous thing, and many shipwrecks are caused by this. Father Cheng was quick; he immediately pulled out a talisman and rushed forward, his eyes filled with a lingering gloom.

Water droplets relentlessly pounded against the metal floor, and against the frozen heartbeats of everyone present. The sound gradually faded, yet in the absolute silence it swelled into an immense terror.

"Emergency!" Xi Xi opened the team's group chat. "Everyone, prepare your cleaning and heating talismans! Now, immediately! Check for leaks in each house!"

After saying that, she returned to her RV through the teleportation array, her eyes fixed on the turbid, churning seawater outside the observation window.

The puppet manatee had successfully turned around. As Xi Xi approached the rear of the vehicle and activated the light screen camera, she commanded, "Stop!"

Not far away, signs of change permeated the depths of the sea—the corals and anemones that should have been supple and gently colored had twisted and grotesque branches, and their colors were strangely bright and glaring.

Scarlet like congealed blood, fluorescent green like flickering will-o'-the-wisps, and thick purple like accumulated miasma, all swirling wildly and chaotically in the murky seawater.

"Could there be something wrong with that coral?" Chu Zhiqin asked anxiously. "Should we take a detour?"

Meanwhile, in the driver's seat, Xi Zhongcang was observing the pixel map on the central screen. The glaringly red area formed a wall. "No! All directions... are blocked by those wildly growing mutated coral reefs. If we force our way through, it's suicide!"

"I'm going out to take a look." Xi Xi's tone was firm, leaving no room for negotiation.

"No, that's too risky!" Xi's mother tried to stop her, but Xi Xi revealed the invulnerable Yin-Yang Talisman of Fuxi from the Celestial Empire.

“But this doesn’t look like poison; it looks more like corrosion.” Xi Zhongcang frowned. “How could poison penetrate the exterior of a motorhome?” He tapped the wall with his knuckles.

Fortunately, Xi Xi's RV was well reinforced and there is no immediate risk of leaks.

“Hmm. I think so too, so…” Xi Xi naturally thought of this, and then took out a gas mask and a protective suit.

This was her failed attempt at creating a stroke of genius, but unexpectedly it came in handy.

She clenched her teeth and pulled the protective clothing over her clothes. The garment was heavy, and the moment the metal buckles tightened, the pressure squeezed her chest.

Xi's parents finally nodded and served Xi Xi the dish of "Jellyfish with Rare Swim Bladder". Then, she took the Whale Transformation Talisman and entered the underground cabin.

The isolation chamber door slammed shut behind me, and icy seawater instantly washed over my entire body.

I slowly swam towards that eerily colored sea of ​​death. The corrosion-resistant suit protected me from direct corrosion; all I could hear was the heavy, drum-like pounding of my own heart and the hissing sound of the coral rubbing against my outer garment.

Xi Xi carefully extended her arm and, through the heavy feel of the gloves, used sampling forceps to cut off several unusually thick coral branches and a few anemone petals that shimmered with a sinister fluorescence.

The faint sound of coral snapping was clearly audible in the still seawater, and soon the pliers in my hand were corroded beyond recognition.

Amidst everyone's tense gazes, Xi Xi successfully returned to the cabin and immediately handed the collected samples to Li Jinshao.

Li Jinshao had a lot of testing equipment inside the submarine, which he collected one by one, driven by his professional instincts.

Time crawled slowly under the weight of the oppressive atmosphere. Every second was accompanied by the crackling sound of the corroding car walls and the agonizing dripping of water.

"Xi Xi! Let's drive back a little further! Our car is starting to leak too!" Liu Yunyan's voice was filled with panic as she pleaded with Xi Xi for help.
