Outside the entrance to the underwater ruins.

After Ye Chen disappeared at the entrance, the communication was also cut off.

Li Muyue clenched her fists tightly, her heart filled with tension and anticipation.

Under her gaze, time seemed to stretch out, slowing down to the point of a snail's pace.

Fifteen minutes later, a tiny ripple began to appear at the once calm entrance, like a gentle breeze rippling across a lake.

Then, the ripples continued to expand, gradually turning from tiny ripples into surging waves, as if a wild beast was rolling inside the spherical space, trying to struggle to break free.

Despite the increasingly intense tremors, even causing the eight spheres to start shaking, the power was firmly controlled by the array.

However, as time went on, the sphere trembled more and more violently, like the prelude to an impending storm.

Cracks even began to appear on the eight spheres, as if they might break at any moment, and wisps of energy began to leak out.

The outer sea could no longer remain calm. As energy overflowed, the entire sea began to churn, like a raging beast, causing tremendous tremors.

Li Muyue had to retreat another fifty meters to barely maintain control of the submarine's attitude and avoid it being capsized.

Her gaze was fixed on the entrance to the ruins, her hand unconsciously touching a red button.

This is the emergency rescue button. Pressing it will cause the submarine to concentrate all its energy into a single point and fire it out.

The energy gathered by the small nuclear fusion device was so great that it could break through space and help Ye Chen escape.

However, this would destroy the cave formation, and the mission to collect the underwater ruins would naturally fail.

Li Muyue bit her lip, her heart filled with conflict. She wanted to press the button immediately, but she was also afraid that she would make a mistake in her judgment.

Time ticked by, the overflowing energy grew, and the surrounding seawater churned more and more violently.

The submarine was like a small boat in a raging storm, barely maintaining a stable posture, and could capsize at any moment.

Li Muyue's face had turned as pale as paper. Her hand was about to press the button several times, but she always stopped herself at the last moment.

The crack in the sphere grew larger and larger, just as Li Muyue was about to press the button.

A silver figure appeared in the center of the wave.

"Mu Yue, it's a success. I have already taken over the cave heaven."

Ye Chen's voice came from inside the submarine, and communication between the mecha and the submarine was restored.

Li Muyue breathed a long sigh of relief, her tense nerves finally relaxing. She sat slumped in her chair, feeling completely exhausted, and her vision blurred.

Only then did Li Muyue realize that her back was already soaked with sweat.

"Mu Yue, are you alright?"

Ye Chen's voice rang out, and Li Muyue reacted, quickly replying, "I'm fine. You should hurry back to the submarine; I think there's a risk of it collapsing!"

Upon hearing this, Ye Chen quickly swam to the submarine and crawled inside through the open entrance.

Li Muyue had recovered by this time. Upon seeing Ye Chen, she couldn't help but hug him tightly, murmuring, "There was such a commotion just now, I almost thought you couldn't get out!"

Sensing her worry, Ye Chen comforted her, "There were some setbacks, but we succeeded in the end."

He glanced at the raging waves outside the submarine and said, "Let's get out first and then talk."

On the way back to the Dragon Palace base, Ye Chen briefly recounted the process of acquiring the cave heaven.

"So, the entrance to this grotto-heaven is now inside this jade bead?" Li Muyue asked curiously, holding a jade bead about three centimeters in diameter and examining it closely.

The jade bead was brought out by Ye Chen from the cave heaven; it is the core of the cave heaven, or, scientifically speaking, the controller.

"The cave is a space cut out from the existing universe. Through this control core, the entrance can be opened at will, and even the basic rules inside can be controlled."

"In the beginning, the cave was a void. It was only by continuously adding soil, air, water, plants and animals that it gradually became a habitable space."

Ye Chen took the stone bead and laughed, "Doesn't this sound a bit like the legendary creation myth of Pangu? Maybe if this cave continues to expand, it will become another universe!"

Li Muyue chuckled and said, "If it really expands into a universe, wouldn't you be the creator of the world!"

“One creator isn’t enough; we also need a creator’s wife, otherwise how can this universe thrive?” Ye Chen whispered teasingly in her ear.

"Virtue!"

Li Muyue rolled her eyes at him, then said, "Now that you've taken over this grotto, you should give it a name."

Ye Chen casually suggested, "How about we call it Mousse Cave Heaven?"

Li Muyue said irritably, "You really are casual."

Ye Chen laughed and said, "A name is just a label. Why don't you choose one?"

Li Muyue's eyes sparkled as she softly asked, "What do you think of calling it Morning Moon Cave Heaven?"

"Chenyue Grotto Heaven?"

Ye Chen repeated it, then his eyes lit up and he laughed, "This name is good, let's call it Chenyue Cave Heaven, Ye Chen and Li Muyue's world!"

"Mmm, my husband is so good!"

Li Muyue said happily, and gave Ye Chen a light peck on the cheek.

"That's not enough!"

Ye Chen laughed, pulled her into his arms, and lowered his head to cover her cherry-like lips.

After a brief moment of tenderness, the submarine had already entered the Dragon Palace base.

Ye Chen stepped out of the submarine with a smile on his face, followed closely by Li Muyue, whose face was flushed.

Upon boarding the automated teleportation platform at the Dragon Palace base, Li Muyue asked, "How do you plan to use the Morning Moon Cave Heaven?"

Ye Chen pointed to the Dragon Palace base in front of him and said, "I plan to move the Dragon Palace base inside. Also, the time flow inside is a hundred times faster than outside, so some scientific research that doesn't require human intervention can be carried out inside!"

Li Muyue clicked her tongue in amazement: "Such a large base, when will it be ready to be moved?"

Ye Chen laughed and said, "It won't be long, Mu Yue, just you watch!"

As he spoke, a round platform floated over, and he took out a stone bead and placed it in the groove on the platform.

The next moment, the stone bead began to light up, and intricate patterns appeared on its surface.

Then, these patterns detached from the stone bead and gradually expanded.

Before long, an entrance about ten meters wide was formed.

"This...this is the entrance to the cave, how did it become so big?" Li Muyue exclaimed, dumbfounded.

"The stone bead is the core of the cave, and it can change the rules inside. Expanding the entrance is a given, and with enough energy, it can even become bigger!"

As Ye Chen spoke, he directly ordered Zhizi, who was controlling the circular platform, to increase the energy input.

As the energy increased, the entrance continued to expand until it reached a width of nearly 50 meters before stopping.

"This width is sufficient. It should take less than two days to move the Dragon Palace base."

Ye Chen said that he had issued the relocation order.
