The stone was enveloped by Qin Che's natural spiritual energy, flying with him as they looked down at the vast ocean, filled with emotion.

"Master, I've never been to a place like this before! What a magnificent sea, so boundless!" Stone seemed very happy, stretching lazily in the air.

In fact, Qin Che was already capable of carrying people in flight. Although the consumption would be twice as great, it was nothing to worry about for Qin Che now.

“The underwater civilization and the imperial civilization stood at the same time and were both brilliant, but they never had any communication with each other, or had very little communication.”

Qin Che murmured, looking down at the ocean. His senses penetrated deep into the sea, even traversing deep trenches, and the land appeared before his eyes as if through a telescope.

Stone said, "That's why the people of the sea wanted to investigate the truth behind the fall of the Empire and obtain the Empire's psionic technology. They almost succeeded."

It's a one in ten thousand chance that Dog Step could withstand the pressure of a demigod battle and steal the Chaos Stone. He managed to find an opening, which is quite impressive.

Although the Chaos Stone has now been absorbed by Qin Che's system, he himself has not gained anything and must wait for the system update in 100 years.

Thinking of this, Qin Che said, "The compatibility of the underwater people with psionic energy is different from that of us wasteland humans. I thought about it carefully, how did Gao Quan manage to withstand the pressure and steal that stone? It must be that the genes and particles of the underwater people are not very compatible with psionic energy. Otherwise, even a mortal would not be able to withstand such spiritual pressure."

Stone remained silent: "Master, where would the underwater people's lair be?"

"I don't know, we can only search slowly, but we still have plenty of time, don't we?" Qin Che turned his head and smiled brightly at the stone.

"Mmm!" Stone nodded happily, swam over in the air, and hugged Qin Che's body in a carefree manner.

"Master, flying is so fast and feels so good," Stone said with a grin.

"Be careful not to fall." Qin Che adjusted the amplitude and intensity of the natural spiritual energy around him. He constructed a 'cloud' so that he wouldn't fall if he stayed on the cloud.

The two sailed on the sea, occasionally encountering tsunamis and waves, but none were larger than the sheer cliffs of the icy plains.

Qin Che ventured deep into the clouds, unleashing his senses to search the entire sea. After countless days, he still couldn't find the lair of the underwater people.

"That shouldn't be the case... Don't they live underwater? Then why do they call themselves that?" Qin Che asked, puzzled.

"Could there be some kind of barrier that we can't see?" Stone asked curiously.

Qin Che shook his head: "Whether it's a barrier created by technology or a barrier of psionic energy, it shouldn't be able to block my senses."

His perception covered the entire ocean, yet he couldn't find the underwater nest. It was strange; could their nest move?

Stone had a sudden inspiration and said, "That must be it. Their nest has moved to the place we searched before."

"Sigh, this is really troublesome." Qin Che sighed, rubbing his forehead. If it was a mobile nest, it would be very difficult to find. His perception couldn't cover the entire ocean, only a part of it.

But the underwater people probably didn't know that there was a demigod in the sky looking for them. Qin Che concealed his aura, so even beings of the same level couldn't detect him.

Along the way, the two encountered some islands, and Qin Che decided to treat it as a vacation, taking Shi Tou on a trip to the islands.

The portable compartment contained ample food and water, as well as daily necessities, changes of clothes, and more.

It's almost equivalent to traveling.

Shi Tou was very happy. Her face, which was in her thirties, had become several years younger during this time. Her skin was supple, smooth, fair and delicate, but even so, it could not hide the slight wrinkles at the corners of her eyes... Shi Tou was getting old after all.

A 90-year-old man took an 80-year-old girl on a long sea voyage, which was very romantic.

In the following days, Qin Che simply slowed down, no longer in a hurry to find the underwater people's nest, but instead took the stone and toured the various islands.

"If only I could live here, secluded from the world," Stone sighed. She had too much to do in the cabinet and wanted to retire.

"After we retire, let's move to the back garden and take a long trip like this every year, how about that?" Qin Che understood and made a promise.

Stone was overjoyed: "Great!"

In some places, the seawater has become viscous and sticky, like paste, as if it had been hit by some natural disaster.

To this day, Qin Che still doesn't fully understand what kinds of disasters exist in the wasteland. They are all strange and unusual, and the green clouds in the desert alone have puzzled him.

In the post-war world, various thermonuclear particles and unknown toxic substances roam freely, and even the vast ocean cannot escape their influence.

Qin Che had been to the Earth Sea, reached ancient Europe, and climbed mountains and rivers. There were even more severely damaged wastelands there, which were completely uncultivable.

Humans can only obtain food and energy through underground hydroponics and photovoltaic solar lamps, but this does not stop them from continuing to build factories on the surface.

The white people of the Green Company are trying to save the world through war, but that will never work. The wasteland must be brought into peace.

Qin Che even took a stone with him and dived into the sea to search. The dark trench was full of monsters, huge schools of fish and ugly deep-sea fish.

Qin Che used his natural spiritual energy to isolate himself from the water pressure and descended to a depth of several thousand meters. At the bottom of the trench, there were some boneless and eyeless creatures.

This made him sigh with emotion. There are countless creatures on Earth, and even with the arrival of the wasteland era, these resilient creatures still cannot be eradicated.

Suddenly, they encountered a huge lanternfish, the size of a giant elephant, which opened its tusks and maw to bite at the two of them.

Qin Che floated up, pushed off with his legs, circled around, and punched the lanternfish on the side of its head, instantly denting it.
