The castle walls were as hard as iron, unaffected by the hail's bombardment.
Reinforced with crystal core energy, the castle walls could withstand any extreme weather damage, ensuring extremely high safety.
Due to the immense wind resistance, the castle's flight speed was very slow.
From atop the castle, they could faintly see a dark mass surging towards their direction from the other side of the sea.
That was the impending tsunami!
Seeing this, everyone's hearts were gripped. They didn't return to their rooms; instead, they stood in the open areas or by the castle walls, awaiting the tsunami and praying for their survival through this disaster.
For them, this was the first time standing in a flying, mobile home, and also the first time witnessing a tsunami, as seen only in movies, actually happening before their eyes.
The water, as tall as a wall, made them feel apprehensive and fearful.
Even though they were inside the mobile home, higher than the wall-like tsunami, they were still afraid.
The castle flew even higher, creating a significant distance between it and the wall-like seawater.
Once it reached a certain altitude, ensuring the castle's safety, it stopped flying forward and hovered in mid-air.
Meanwhile, in the control room, Shang Qi was already seated at the console with Su Ling. The console was transparent, allowing them to sit inside and clearly see everything happening.
Su Ling watched the ever-rising wall of water surge towards the sea island, sweeping past beneath her. The immense commotion directly impacted the flying mobile castle, making it feel the tremendous power of the tsunami.
Su Ling's gaze followed the sky-filling curtain of water, witnessing firsthand as it engulfed and covered the sea island's dock. It then proceeded upwards into the lower-lying areas of the sea island, unobstructed, unrestricted, and devastating everything.
In just a few minutes, the sea island, which Su Ling and the others had chosen as their base for survival in the apocalypse, disappeared from their sight, replaced by a vast ocean.
The sea island itself had already slowly sunk into the seabed with the arrival of the tsunami.
Everything happened in an instant. After that instant, everything had undergone a cataclysmic change.
Su Ling watched everything that unfolded without much emotion or profound feeling.
Stretching lazily, Su Ling tilted her head and looked at Shang Qi, "We really have to thank Jiang Jiang this time; otherwise, we would have been in trouble."
Had they not evacuated in time, all of them would have become sacrifices to this earth-shattering tsunami, vanishing into history along with the sea island.
Because of Jiang Jiang's forecast, they had evacuated early and witnessed the arrival of a tsunami, bearing witness to history.
Shang Qi nodded, taking Su Ling's hand. "The castle can now navigate underwater. Let's show everyone how beautiful the underwater world is."
"But I think, no matter how beautiful it is, it can't compare to the underwater world in A'ling's space."
That was a marine world untouched by overfishing, unexploited and unpolluted by humans, and unmodified by human hands—the most natural, pristine, and ecologically undamaged ocean world. Such beauty was indeed incomparable.
"Okay," Su Ling agreed. She fiddled with the console, and the castle began to descend slowly.
As the castle descended, Su Ling input the program, with the target destination being Lu City.
Once all operations were complete, she looked at Shang Qi, "You can go call them now."
For viewing the sea, the fully transparent control room was the most awe-inspiring place.
She still had some preparatory work to do. The console couldn't be touched carelessly; she needed to design a program to protect it.
