Soon, the Celestial-level Creatures from the Meng Star Civilization reached the surface and then used their teleportation abilities to travel deep into the earth.

"He went underground. Do you have the ability to traverse the earth, or perhaps some special tool?" Yang Yuan asked.

"No."

Zhao Jiayan shook her head, "How about we just dig our way down? With our strength, this earth can’t stop us anyway."

At this time, Jiang Yiyi suddenly said, "Brother Yang Yuan, Sister Jiayan, my ability can directly traverse matter."

Yang Yuan and Zhao Jiayan looked over in surprise, "Your ability can traverse matter?"

"Yes. My ability is the Observer, observing everything outside, whether it’s matter or energy, it can all be ignored."

Jiang Yiyi said.

Instantly, Yang Yuan and Zhao Jiayan were both amazed and felt the magic of Jiang Yiyi’s ability even more.

"In that case, let’s follow." Yang Yuan said. 𝑓𝑟𝑒𝘦𝓌𝑒𝑏𝑛𝑜𝘷𝑒𝘭.𝒸𝘰𝑚

"Okay, okay."

Jiang Yiyi immediately took them both underground, speeding down deeper into the earth.

Yang Yuan and Zhao Jiayan realized the earth before them seemed like an illusion, not hindering them at all.

"This Observer ability is truly magical, it can ignore everything external." Zhao Jiayan marveled.

Jiang Yiyi’s ability initially was just a sense of security, a passive perception of everything around.

Later, it gradually became a passive ability, automatically disappearing when attacked, entering another realm, allowing her to attack others while remaining unreachable.

This was already quite extraordinary.

Now it’s even more extreme, she can ignore everything around her, even the earth.

When she surpasses the Celestial-level, will even Demon God Level beings be unable to touch her?

Zhao Jiayan and Yang Yuan pondered this as the three of them continued at speed, tracking the Celestial-level Creatures from the Meng Star Civilization.

Because of Jiang Yiyi’s perceptive ability, Yang Yuan and Zhao Jiayan did not release any Divine Thought, avoiding alerting their target.

After all, Jiang Yiyi’s ability could ignore others’ perception, her ability was not Divine Thought, but a kind of rule.

Suddenly, Jiang Yiyi said, "There’s a huge space deep underground, with a massive structure inside."

Yang Yuan was immediately intrigued, then said, "Yiyi, speed up, let’s get there first."

"Alright." Jiang Yiyi nodded, and then quickened her pace, taking the two of them as streaks of light flying towards the depths of the earth.

Before long, they outpaced the Celestial-level Creatures from the Meng Star Civilization, reaching the core of the planet.

Indeed, there was a gigantic palace here.

It could indeed be described as a palace, and it was truly enormous, giving a majestic feeling.

But bizarrely, from a physical perspective, this building was only a few dozen meters high.

Yang Yuan looked at this building, his eyes shining with a strange light.

Because this building was released by the Demon God Level entity from the Game Government before.

After this building merged into the atmosphere of the Rainbow Heron Star, it suddenly vanished. It was assumed that it had merged with the entire planet, but unexpectedly, the building ended up here, placed at the planet’s core.

"Judging by the exterior, this planet should have just been discovered, right? When was this building constructed? Could it have been built by the intelligent beings of Rainbow Heron Star themselves?" Zhao Jiayan curiously asked.

Yang Yuan immediately recounted what he had seen.

Zhao Jiayan’s eyes lit up with surprise, "Could this be the so-called Authority Building?"

"Perhaps."

Yang Yuan nodded, then walked towards the door.

As he approached the door, he suddenly felt an invisible barrier.

He easily passed through it, but Jiang Yiyi and Zhao Jiayan were blocked outside.

Yang Yuan’s mind flickered, as the descending Celestial-level Creature from the Meng Star Civilization was just at the initial Celestial grade.

So he said, "Wait for me here."

He strode in, reaching the door’s entrance and pushed it with force.

Unsurprisingly, the door opened easily.

Inside, there was an incredibly vast world.

It had its own sky and earth.

It was like an independent small world.

He entered curiously and opened the Door of Arbitrariness to bring Zhao Jiayan and Jiang Yiyi in.

Closing the Door of Arbitrariness, Yang Yuan looked at this small world.

Zhao Jiayan suddenly exclaimed, "This truly is a world, not an illusion. I feel a perfect sensation. I never expected the interior of this building to be like this."

Jiang Yiyi said, "Brother Yang Yuan, there’s something at the center of this world."

"What is it?" Yang Yuan’s eyes twinkled.

"I don’t know, I just sense something there, but I can’t see it, how strange." Jiang Yiyi said, this being a very rare occurrence for her.

Yang Yuan and Zhao Jiayan exchanged glances, then the three simultaneously soared into the air, flying towards the location Jiang Yiyi had mentioned.

Soon, they flew over mountains, plains, rivers, and fields, finally—

They arrived at the very center of this world.

Here, they saw a building identical to the one outside.

Strangely, aside from Yang Yuan’s own Divine Thought Power scan, Zhao Jiayan and Jiang Yiyi couldn’t sense it at all.

Even Jiang Yiyi’s special observational ability could only vaguely feel something here.
