"My Lord, you should still remember what I told you last time about the five generations of kingdoms ruling under our feet, right?"

Gu Bo asked.

"I remember."

"Ever since the rise and destruction of the Sand Empire more than 8,000 years ago, this land under our feet has experienced another four generations of kingdoms."

"The latest kingdom is the Aurora Kingdom, which borders our territory."

Blood Bat said.

Its voice was a little sharp.

Gu Bo nodded and pointed at the murals.

"This mural describes the history of two ancient kingdoms that have ceased to exist."

"One of them is called the Violent Storm Kingdom, and the other is called the Ancient Gold Kingdom."

"If the four kingdom eras after the Emperor of Sand are called the four kingdom eras, then the era they belong to is the second generation of kingdoms after the Sand Empire."

"They were about 3,000 to about four years ago."

"It doesn't say much else."

"The content on this mural roughly describes that these two kingdoms were mortal enemies in that era."

"The content on this mural roughly describes that these two kingdoms were mortal enemies in that era."

"The prince of the Violent Storm Kingdom and the princess of the Ancient Gold Kingdom developed feelings for each other because they fought many times on the battlefield."

"The two of them were already tired of war, so they wanted to use a union between them to resolve the hatred between the two countries."

"But the enmity between the two countries is already deep. How can a man and woman in love resolve it?"

"That's not all."

"The union of the two was also strongly opposed by the higher-ups of both countries."

"Eventually."

"This pair of prince and princess stabbed each other to death with their swords and died for love together."

"But to the two countries' surprise"

"After they died, their souls became powerful vengeful spirits."

"This pair of vengeful spirits destroyed the Violent Storm Kingdom and the Ancient Gold Kingdom and turned the dead citizens of the two countries into their undead citizens."

"After that, the vengeful spirit couple who destroyed two kingdoms woke up to their senses."

"After they saw this scene, they finally decided to seal themselves and all the undead citizens deep in the ground and use storm magic to transform the area where the sealed place was into a natural disaster forbidden area in order to save themselves and not let these undead hurt others."

"This is the origin of this Sandstorm Forbidden Land."

"As for the vengeful spirit couple, they are the 'King of Eternal Silence' and the 'Queen of Eternal Silence'."

Zhou Zhou and the surrounding people fell silent.

The Blood Bat sighed softly.

Zhou Zhou did not expect this.

These Undead creatures actually had such a sad story.

"According to the ancient books."

"After the Violent Storm Kingdom and the Ancient Gold Kingdom were destroyed by two nameless powerful vengeful spirits, they disappeared without a trace. Even their corpses disappeared."

"This has even become an unsolved historical mystery."

"I didn't expect the real reason to be like this."

Gu Bo also sighed.

As soon as he finished speaking.

An energy fluctuation appeared in his body before disappearing.

The Blood Bat was stunned.

Then, he opened his personal information and realized that the other party's archeologist level had increased from the previous White Silver-Tier Elementary Grade to White Silver-Tier Advance Grade.

He was a little tongue-tied and there was nothing much to say.

This was what life professions were like.

It was different from combat professions that needed to accumulate promotion energy bit by bit.

Once a life profession made a breakthrough in innovation, it was very likely to increase by more than one grade.

It was normal to increase by a few grades.

As an archeologist, Zhou Zhou even felt that it was too little for Elder Gu to crack an unsolved historical mystery and raise it by two grades.

That was indeed the case.

After a moment of silence, Gu Bo smiled at the Blood Bat.

"If I publish the historical answer here, I'm afraid I'll directly be promoted to a Yellow Gold-Tier or even White Platinum-Tier archeologist."

"Are you going to publish it?"

Blood Bat asked.

"I'm not going to publish it."

"If the truth is really as the murals say, I'm afraid this place will be in chaos if I announce the truth about this place."

Gu Bo shook his head.

The Blood Bat nodded.

There were not only the undeads of the two kingdoms here.

It also had all the wealth accumulated by the two kingdoms.

Just as Old Gu had said, if the others knew the truth of this place, this place would indeed be in chaos. Even his territory might suffer.

Moreover, he wished that these two kingdoms would never come out.

Otherwise, he would be the first to suffer if they had any bad intentions after coming out since his territory was connected to this place.

He was a small faction that was not even a kingdom. He could probably not resist in front of these two big shots who could even destroy two kingdoms.

Then, he did not say anything about keeping it a secret.

"Elder Zheng."

"Don't sell the matter here as information."

The Blood Bat flew to Zheng Fugui's shoulder and smiled.

"Yes, my Lord."

Zheng Fugui said respectfully.

Blood Bat nodded. Then, he suddenly remembered something.

"By the way,"

"How did you get in if this place was sealed?"

"Is it also because of the Unlimited Right of Passage?"

Blood Bat asked.

"Yes, my Lord."

"As long as it's a secret faction that our Mysterious Caravan knows about and its faction level is below the Kingdom-level."

"No matter how secretive it is, we have the right to enter and conduct business."

"But it's only limited to doing business. It can't do anything else."

Zheng Fugui said.

Zhou Zhou clicked his tongue.

Even though there were some restrictions, this Unlimited Right of Passage still felt ridiculously strong.

"My Lord, Mr. Gu, we can talk about these things outside the seal."

"But if you enter the spatial teleportation array, it's equivalent to entering the sealed Kingdom of Eternal Silence."

"We have to be careful when the time comes. Otherwise, the identity of the Lord and Mr. Gu might be seen through."

"Even though they might not do anything because of our status, there might be accidents."

Zheng Fugui said seriously.

The Blood Bat and Gu Bo nodded.

The two of them, especially Zhou Zhou, could naturally feel Zheng Fugui's sincere concern and care.

After that, everyone did not say anything else and walked into the spatial teleportation array.

Eternal Silence Kingdom.

After Zhou Zhou saw his surroundings again, he realized that he had arrived at a dead city.

In this city.

Tailor shop, blacksmith shop, carpenter shop, grocery store, jewelry shop

There were all kinds of buildings.

Moreover, they were all functional blueprint buildings, not self-built buildings.

However, even though the buildings were complete, there was no one alive here, and the aura of the undead was extremely strong. The dim green light illuminated the city, and coupled with the dead atmosphere, it made this place look a little eerie and terrifying.

Zhou Zhou frowned slightly.

His sixth sense was astonishing, he could sense that a large number of undead creatures were sleeping in these buildings.

Tap, tap, tap

A pair of Undead Knights wrapped in black undead aura galloped over on undead warhorses.

After coming close, leading Undead Knight jumped down from his horse and walked in front of Zheng Fugui.

"Welcome to the Eternal Silence Kingdom."

"His Majesty and the Queen have been waiting in the palace for a long time."

"Please follow me."

His voice was hoarse.

Zheng Fugui nodded slightly and did not speak, looking unfathomable.

However, the other party liked this very much.

He looked at Zheng Fugui and the mysterious caravan members behind him in awe. Then, he led Zheng Fugui and the others towards the palace.

Zhou Zhou originally wanted to investigate the other party's attribute information.

But he thought of what Luo Bu had said to him before and held back.

"My Lord, if you want to understand his information, you can check it directly."

"The mysterious caravan uniforms on you and Mr. Gu Bo are not just ordinary clothes."

"Even the vengeful spirit couple won't be able to discover that."

Zheng Fugui seemed to have sensed what Zhou Zhou wanted to do and sent a mental message.

Zhou Zhou was a little surprised when he heard this. Then, he immediately looked at the Undead Knight.

Zhou Zhou could not help but be shocked after reading it.

On the one hand, he was shocked that the other party was actually an Extraordinary-Tier hero.

On the other hand, he was shocked that the "Secret Hero Inheritance Manual" could actually be dropped by killing heroes!
