Chu Wanwan and Si Mingye flew forward for a short while before they discovered a city.

This city is different from any city Chu Wanwan knows.

Its city walls soared into the clouds, seemingly constructed entirely of a dark stone that emitted a faint glow, giving it a solemn and mysterious feel. Engraved on the walls were symbols that Chu Wanwan couldn't understand, which seemed to tell the ancient legends of the city.

The city's interior boasts a unique architectural style unlike anything Chu Wanwan knew. These buildings seem to blend nature and artifice, possessing both primitive charm and exquisite beauty.

On the streets, people dressed in strange costumes busily moved about...

Chu Wanwan and Si Mingye landed not far from the city gate. As they approached, they immediately attracted the attention of the guards. The guards wore long black robes of some unknown material and held spear-like weapons, watching them warily.

A guard came up to them and spoke a lot of gibberish in a language they couldn't understand.

Chu Wanwan and Si Mingye exchanged a glance, both looking completely bewildered.

When the guard saw that the two ignored him, he became enraged and charged at them with a weapon that resembled a spear.

Chu Wanwan and Si Mingye did not move, but the spear stopped one centimeter away from them. How could human weapons break through their protective divine power?

Seeing that the spear could not penetrate, the guard glared at them warily, muttering something unintelligible.

As soon as he finished speaking, several guards behind him stepped forward, their spears aimed at them, beams of light emanating from them. These beams struck Chu Wanwan and Si Mingye's protective divine power, creating small craters in it.

Although it didn't penetrate, the sheer power of the attack still sent a chill down Chu Wanwan's spine.

"Let's leave first!" Si Mingye took Chu Wanwan's hand and leaped into the air.

Seeing the two leave, the guards did not chase after them, but instead turned around and went back into the city to report.

Chu Wanwan and Si Mingye arrived at a dense forest...

Chu Wanwan patted her chest and said to Si Mingye:

"Could this be the legendary prehistoric civilization? It's incredibly powerful! The weapon of a mere city gate guard could actually break through our protective divine power! If war were to break out in this world, it would undoubtedly be the end of the world!"

I suspect that the extinction of dinosaurs in the future will actually be due to those people!

Si Mingye listened to Chu Wanwan's words, seemingly understanding but not quite. He asked Chu Wanwan to take out the Ancient and Modern Compendium and inquire about the situation of this world.

Following Si Mingye's advice, Chu Wanwan took out the "Tonggu Jin" (a magical artifact) from her spatial storage.

"Throughout history, why do the humans here possess such powerful abilities? Their weapons can emit a light that is extremely destructive, capable of even penetrating our protective divine power!"

What kind of world is this?

Ripples spread across the mirror's surface, which seemed to connect the past and present, and then the mirror projected the world's events onto the surface like a projector.

The mirror reflects a world where dinosaurs and humans coexist. The human settlements are surrounded by high walls made of black stone, seemingly to prevent large carnivorous dinosaurs from entering the city...

"This world is the world of dinosaurs, but besides dinosaurs there is another advanced civilization, a civilization that transcends the so-called modern society you have experienced."

Their weapons are highly advanced, capable of fighting against even lower-level gods, which means you are in great danger!

Tong Gujin suddenly spoke up.

"Damn! Is this what they mean by the end of science being theology? These people can contend with God, can they still be called human?" Chu Wanwan was shocked.

"They are the ancestors of humankind, and the modern humans you see are their descendants. Many similar small worlds go through this process. First, they develop a highly advanced civilization, and when that civilization reaches an absolute level, it is nearing its destruction."

Because less advanced civilizations cannot pose a significant threat to the world, while highly developed civilizations have the capacity to destroy it.

Humans are inherently greedy; they will wage war for profit, and the price of war among advanced civilizations is the destruction of the world,” Tong Gujin explained.

Chu Wanwan was speechless with shock after hearing Tong Gujin's explanation. She had always believed that the more advanced technology became, the stronger humanity would be, but now it seemed that everything had two sides. Excessive technological advancement wasn't necessarily a good thing.

"So, in the modern society I once lived in, the claim that the dinosaurs went extinct because of an asteroid impact was wrong? And that the dinosaurs were ultimately destroyed by our ancestors?"

Chu Wanwan exclaimed in shock.

"Perhaps! The exact history will only be known when I go to the world where my master once existed. But what I can tell my master is that most of the smaller worlds are in a cycle, and they are quite similar."

Barring any unforeseen circumstances, the master's guess should be correct!

Tong Gujin spoke mechanically in a childlike voice.

"Okay! I understand!" Chu Wanwan said, putting Tong Gujin into her spatial storage.

"What should we do? Should we intervene?" Si Mingye asked, frowning.

"This time, let's not stop the march of history. I want to stay here for a while and see how the world has developed. I want to see how the dinosaurs went extinct, how humans made such a fatal mistake, and how primitive humans came into being!"

Chu Wanwan felt that she shouldn't interfere with the world's progress. After all, to stop the war in this world, the civilization of this society would have to be destroyed. She couldn't just take action and wipe out everyone in this world!

Otherwise, even if she successfully prevented a war for a certain period of time, such an advanced civilization would eventually destroy the world!

Since we can't stop the course of history, let's just look at it from an outsider's perspective.

Si Mingye nodded in agreement: "Let's get the Heavenly Stone first."

Si Mingye and Chu Wanwan were not in a hurry to return to the Immortal Realm because the flow rate of the small world was different from that of the Immortal Realm.

For example, in the previous world, they stayed for three years, while only three days passed in the Immortal Realm. Therefore, they had ample time to stay here and observe the so-called prehistoric civilization for a while.

"Alright!" Chu Wanwan responded, then summoned the Azure Flame and headed towards the location of the Heavenly Stone...

This time, the Heavenly Stone was located inside the volcano. Chu Wanwan and Si Mingye stood above the crater, looking down at the rolling lava and the blue stone that was faintly visible in the lava. That blue stone was their goal for this trip—the Heavenly Stone.
