Before us, the bridge piers of the cross-sea bridge stand amidst the morning waves.
These bridge piers are made of solid concrete and steel bars. Their surfaces were originally smooth and flat, but over the years, they have been eroded by the sea and have deep marks on them.
These marks, some deep, some shallow, some wide, some narrow, crisscross and record the contest and symbiosis between the sea and the bridge piers.
The traces looked so familiar… Xi Xi suddenly realized.
The photos that Liu Enxi had sent her earlier kept popping into her mind.
The interior of the cave is clearly visible in the photographs. Notably, the regular erosion marks are almost ubiquitous throughout the cave.
Furthermore, the presence of sea spiders in the area suggests that all these signs clearly indicate that this place was flooded by seawater during high tide!
However, this seemingly reasonable inference was soon challenged.
As far as she knew, the Yoo Eun-hee sisters had been in that mysterious cave for several days, but they had never mentioned or experienced a situation like high tide.
Judging from the photos, the location of the albino female NPC and the surrounding environment are unusually dry, which could not have been formed in just one or two days. This can only prove that this place has not been washed by seawater for a long time.
Logically speaking, tidal patterns are very stable, so what has caused the cave to become so dry?
In an instant, countless questions flooded her mind, plunging Xi Xi into deep thought.
"What's wrong?" Chu Zhiqin looked at her daughter with some confusion, and seeing Xi Xi's worried face, she couldn't help but feel concerned.
“Mom, look here.” Xi Xi pointed to the bridge pier not far away. “The waves here are one after another. It’s obvious that the salt and other chemicals in the seawater have a continuous corrosive effect on the bridge pier, so there are mottled rust spots and peeling on the surface of the bridge pier.”
"Especially in areas with large tidal ranges, look here, the lower part of this piece is clearly subjected to the scouring and erosion of seawater, and has even formed these unique shapes and textures."
Xi Xi reversed the car back to the side of the cross-sea bridge, then turned off the engine and continued, "This kind of corrosion caused by seawater erosion is very common, but if there is a place with this kind of erosion texture, yet it is very dry, what is the reason for that?"
Chu Zhiqin listened to Xi Xi's rambling explanation with a mixture of understanding and confusion, then waved her hand and declined, saying, "How would I know... I've hardly ever seen the sea."
Chu Zhiqin thought for a moment and then said, "Speaking of water, I only remember when my village was flooded when I was a child, the garage, which was usually very sturdy, was washed away and completely submerged. The power of water is not to be underestimated."
As the waves surged in, Xi Xi seemed to realize something, recalling her discussion with Li Jinshao about the painting "Tide Star" during their exploration at Dongli Post Station that day.
Xi Xi vaguely remembered that Li Jinshao had said that due to the erosive action of seawater and waves, the contact zone between the mountains and the sea may be eroded by the waves, causing cavities at the bottom of the mountains, which in turn leads to the collapse and reshaping of the terrain.
Something terrible has happened... Xi Xi's expression suddenly turned serious. She suddenly realized something, opened the light screen, and dialed Liu Enxi's light screen connection.
While keeping an eye on the connection on the light screen, Xi Xi stood up and gestured for her mother to come to the terrace with her. Chu Zhiqin nodded knowingly, took out a vehicle talisman, and followed Xi Xi upstairs.
After a long busy tone, the connection was finally established, and Xi Xi immediately took out the Magic Rhythm Telescopic Ladder.
Xi Xi (Ping): "Hurry up, find the exit and escape!"
As Xi Xi skillfully climbed, she spoke to the light screen.
Xi Xi (Ping): "We can try again on the original road that collapsed due to the earthquake. Don't give up any chance of survival! Time is very tight. Not counting today, we only have three days left!"
However, there was only silence on the other end of the line.
Xi Xi was a little puzzled. Just as she patted her trouser legs and stepped back onto the cross-sea bridge, a familiar voice, accompanied by a weak and hoarse tone, entered her ears.
"Xi Xi...is it really you!? Xi Xi!?"
Xi Xi was taken aback at first, then immediately went back to the interface to check the person she was connected to. After confirming that it was indeed Liu Enxi, she hesitated for a long time before tentatively asking, "Liu... Liu Yunyan?"
As expected, the person on the other end of the call cheered, followed by a series of rapid coughs.
Liu Enxi, Liu Yunyan… Ah? Liu Enxi's comatose sister is actually Liu Yunyan?! Liu Enxi is actually Liu Yunyan's older sister?!
Xi Xi, standing by the roadside, was shocked. A gentle breeze ruffled her hair, and her hand, which had just received the vehicle talisman from her mother, froze in mid-air.
Liu Enxi (Ji): "Miss Xi... I really didn't expect you to be the one Yunyan often mentions!"
Liu Enxi (Auspicious): "Thanks to you, Yunyan woke up! She even woke up before me!"
Liu Yunyan : "My God... cough cough, sister, your memory is just unbelievable! No wonder you were swindled out of everything by that Cui Quan!"
Liu Yunyan (Xiao Ji): "Xi Xi! You've joined our temporary team?! That's great! We're saved! We're saved!"
Xi Xi was speechless for a moment, feeling somewhat incredulous. She wondered why Liu Yunyan, who was usually very talkative, hadn't messaged her for so long. Turns out she was unconscious!
