Outside the underground ancient city, more than 20 cultivators from the four sects of Qi training stopped on a pile of rocks under the leadership of four foundation-building monks.

"I really didn't expect that this underground ancient city was so big, no less than the capital on the ground. Moreover, the buildings of this ancient city were quite similar to the capital above. There were ordinary houses on the outside and an inner city inside. Could it be that this underground ancient city was once the capital of a country, and that inner city was the imperial city?" The young foundation-building monk of the Nine Formation Sect looked at the ancient city ahead, with a hint of thought in his eyes.

"The capital of a country? It should be impossible. After all, the history of the mortal country of Jiang Kingdom has been traced for nearly tens of thousands of years, but I have never heard of any country Kyoto falling underground!" The young man in the white robe of Wanjianmen shook his head slightly.

"Sleeping underground? Haha, fellow Taoist is afraid he was wrong. This ancient city should have been built directly underground." The old man in the black robe of the Demon Sect smiled and looked at the ancient city with a strange look.

At this time, several other monks in the Foundation Establishment Stage couldn't help but look at it. Even the golden-robed Taoist priest from the Xingxing Sect was slightly looked at it.

"Fellow Taoist has seen something, can you tell me?" The young man in the white robe raised his eyebrows and asked directly.

"I just thought of a secret that was vaguely recorded in the sect. It was related to the disaster in the entire immortal world ten thousand years ago. As for the authenticity, I cannot confirm it." The old man in the black robe of the Demon Sect sniffed his nose, took a sip of the gas around him, closed his eyes and felt it carefully.

"The disaster in the immortal cultivation world tens of thousands of years ago? But that invasion of the ancient demon world!" The young man from the Nine Formation Sect exclaimed and asked in disbelief.

"Apart from the invasion of the ancient demon, what else can be called a disaster in the world of immortal cultivation!" The old man in black nodded.

"Brother Dao, don't keep it a secret. We have heard of the invasion of the ancient demons, but is there any connection between the invasion of the ancient demons and this underground ancient city? Could it be that this ancient city was built by those ancient demons?" The young man in the white robe frowned and continued to ask.

"According to the sect's records, the main target of the ancient demon invasion was not our earth, but the Central Earth Jin Kingdom. Our earth was just occupied, but even so, our earth was still unable to resist the invasion of the ancient demon. The entire earth cultivator cultivator died in battle to more than 70%. In the end, only some large sects fled overseas with remnants of power, which made the earth cultivator cultivator not extinct. After the earth was occupied by the ancient demons, many mortals were enslaved and many demon kingdoms were established. I think this underground capital is the capital of one of the demon kingdoms, so that this can explain why this capital was not included in the sect's records. After all, human cultivators had lost control of the earth cultivator at that time." The old man in black robe explained word by word, and at the same time, there was a little more heat in his eyes looking at the ancient city.

It's no wonder that this old man in black robe is a cultivator of the Demon Sect, and all he practices are magic skills. This underground ancient city is related to the ancient demon clan. Maybe he can leave some things related to the demon clan, which may be of great help to these demon cultivators.

"The country is called Yue, and its territory covers the three countries around Jiangguo. It was built three years after the ancient demons invaded the land north. The royal Ye surname existed for more than ten years. Then it disappeared overnight because of unknown reasons. At the same time, more than one million mortals disappeared. It turned out that they were all here." The golden-robed Taoist priest from Shengxing Sect looked at the ancient city, with some inexplicable expressions in his eyes.
