"What? The Returning to the Void Realm!" Chen He exclaimed in shock.

Rowling's expression changed, and Xu Ping'an inadvertently plucked out several hairs from his beard.

"This...this joke isn't funny, my Lord City Lord," Xu Ping'an said with a wry smile, stroking his beard.

Night Wind said seriously, "I'm not joking with you guys."

Zijing's legs trembled, and her teeth chattered together.

"Should we leave?" Zijing tugged at Yefeng's sleeve, looking at him pitifully.

Night Wind said seriously, "Are you sure? If we leave in a hurry without figuring out what dangers are here, and then pretend there's nothing here, how is that any different from ostriches?"

"An ostrich?" Rowling looked at Nightwind with a puzzled expression.

There are no ostriches in the Lingluo Great World, so Rowling doesn't know what an ostrich is.

Night Wind had no choice but to explain: "The ostrich is an extinct creature. When it encounters danger, it will bury its head in the sand and pretend that the danger does not exist."

"And then?" Rowling asked again.

"And then they went extinct," Night Wind said, spreading his hands.

Night Wind was obviously making things up, but he said it to explain the point and make Rowling and the others realize that they couldn't ignore the potential dangers.

If left unchecked, it will be too late when the danger finally erupts in the future.

"As expected of someone who has lived from seven hundred years ago, Lord City Lord, your knowledge is truly vast... Could it be that ostriches were creatures from the Luo Feng Empire era?" Xu Ping'an asked curiously.

“Yes,” Night Breeze nodded.

The Luo Feng Empire was the super empire that unified the continent and the entire human race seven hundred years ago.

The Luo Feng Empire was established five thousand years ago and perished seven hundred years ago.

The sudden appearance of the Crimson-Tailed Beast destroyed the Luo Feng Empire. The survivors fought bravely and finally repelled the Crimson-Tailed Beast. Afterwards, the survivors established two countries.

One is the Hongtian Empire, and the other is the Divine Sword Empire.

This is the history of the development of the human race and the rise and fall of empires in the Lingluo Great World.

But now is not the time to give these people a history lesson, so Ye Feng didn't waste too much breath on this topic.

But the night wind now has to stop.

He was blocked by a heavy bronze gate.

This heavy bronze gate is ten meters high and seven meters wide. It is very magnificent and must weigh at least tens of thousands of kilograms!

Moreover, there is a very complex formation on the bronze gate.

At this very moment, Night Wind, Rowling, and the others were standing right in front of this bronze door.

"I never expected there to be such amazing architecture here... It seems my previous judgment has to be overturned," Xu Ping'an said.

Xu Ping'an had previously mentioned that a senior master might be living in seclusion here, but the appearance of this bronze gate now means that such a possibility is definitely not possible.

The reclusive masters who cultivated here would never have created such a magnificent bronze gate.

Moreover, if the main gate alone is so magnificent, then the entire building must be extremely large!

“If everything here makes sense, then the ancient buildings hidden underground are probably a little bigger than the imperial palace of the Hongtian Empire!” Ye Feng said heavily.

"Where exactly is this place?" Chen He asked.

“I am researching it.”

As Ye Feng spoke, he raised his right hand and waved it, and a storm was born, blowing away all the soil that filled the entire bronze gate.

The bronze gate was fully revealed to Ye Feng and the others, with several large, elegant characters above it: First Spirit Beast Research Institute.

Looking at the large characters, everyone present showed deep confusion.

"What does 'First Spirit Beast Research Institute' mean?" Chen He asked.

“Spirit beasts… do you mean demon beasts? There’s not much difference between spirit beasts and demon beasts,” Rowling said.

"What do you mean by 'first'? This is the First Spirit Beast Research Institute, so does that mean there's a Second Spirit Beast Research Institute, or even a Third Spirit Beast Research Institute, elsewhere?" Xu Ping'an continued.

Night Breeze led the way, saying, "Old Xu's deduction is very reasonable; there probably really are other spirit beast research institutes."

After a pause, Ye Feng continued, "Do you think it's possible that the Luo Feng Empire discovered a spirit beast located here many years ago? This spirit beast possesses terrifying strength and is very likely a Void Returning Realm being!"

"However, for some unknown reason, this powerful spirit beast fell into a state of immobility. So, in order to find out the reason, the Luo Feng Empire built a massive underground research institute here to study the spirit beast."

"And the terrifying aura we just felt came from that spirit beast."

Night Breeze's words made Luo Lin and Xu Ping'an nod repeatedly.

Although this is just Ye Feng's wishful thinking, it sounds quite reasonable.

At least for now, this is the most reasonable and logical explanation.

“We should open this door; only then can we know whether the city lord’s speculation is true,” Xu Ping’an said.

Rowling thought for a moment, then nodded and said, "I think so too."

Zijing shook her head repeatedly: "No, no, what if that Void Returning Realm demon beast escapes after we open this bronze gate? That's a Void Returning Realm demon beast! The world will be in chaos!"

Upon hearing Zijing's words, Xu Pingan and Luo Lin immediately showed hesitation, indicating that they also had similar concerns.

Chen He chuckled and said, "I think it's better to open it. Even if we don't open it, won't that monster come out? If this bronze gate can't even stop us, how could it possibly stop a monster at the Void Returning Realm?"

"So, if that monster could come out, it would have come out long ago. Since it didn't come out, it means it can't come out. In any case, it has nothing to do with this bronze gate. It's obviously impossible to imprison a Void Returning Realm monster inside with just a bronze gate."

Chen He's words made a lot of sense, and Luo Lin and Xu Ping'an were immediately convinced.

Zijing thought about it very seriously, then nodded and said, "It seems that's really the case..."

"The question is, can we open this bronze door?" Xu Pingan asked.

After a moment's hesitation, Xu Pingan said, "Excuse me for being frank, but I can't understand the defensive formation on this bronze gate at all."

“I can understand it,” Ye Feng suddenly said.

Xu Ping'an was shocked: "What? City Lord, you can understand it? Yes, yes, City Lord, you are not only a Saint Realm expert, but also someone who experienced the Luo Feng Empire era. It's not surprising that you can understand it."
