From Gu Lianyue's mouth, the distant years covered in dust slowly unfolded to Gu Chen.

In ancient times, there was a great catastrophe, the exact reason of which is unknown for a long time, only known that in that battle, a peerless power shot at the pale yellow ancient star from the depths of the universe, piercing through the entire ancient star.

The ancient star was pierced through a hole close to the center of the earth, and the cracks in this hole spread to the entire surface. The once vast continent disappeared without a trace, and most of the area was turned into an ocean, leaving only a few isolated continents. There are Faerie Continent and Kunlun Continent.

That catastrophe changed the landscape of the entire pale yellow ancient star, and the huge void inside the earth's core spread to the continental shelf, forming a special place like Tiankeng Earth's Eye.

In other words, the Tiankeng's eye leads to the center of the Canghuang ancient star, which is an extension of the hollow in the center of the earth on the surface.

"Is this the origin of the Tiankeng Earth Eye?"

Gu Chen was shocked when he heard the words, what kind of divine power would it take to penetrate an ancient star, and what scale did the war in ancient times reach?

What Gu Lianyue told him was like a fantasy. If she told it to ordinary people, she would definitely scoff and think it was a joke.

But when Gu Chen thought of the fragmented surface of the Deep Demon Sea, and when he gradually approached the eye of the Tiankeng, the gravity he felt continued to strengthen, and he couldn't help but believe her statement.

"There are several places like Tiankeng Earth's Eye on the Canghuang Ancient Star. It is said that there is a glacier abyss on the Sky Burial Continent, which also leads to the center of the earth. These are all recorded in the ancient books left by my ancestors of the Gu family. , now the only ones on the mainland who know such secrets are us and the senior officials of a very small number of forces such as the Thirteen Immortal Sects." Gu Lianyue added.

Gu Chen took a deep breath, "I understand the origin of the Tiankeng's Eye, but just now you said that this place is related to the opportunity to become an immortal, so what's going on?"

"In ancient times, before the catastrophe happened, the Canghuang ancient star cultivation civilization was extremely prosperous. The number of immortals was far greater than today, and the connection with the universe was also very close."

Gu Chen nodded, he had heard about these things a long time ago, and it can be seen from some descriptions in the Enandu Sutra that he also discussed this matter with Gu Ziyan.

"But after that catastrophe, everything changed. Because the body of the ancient pale yellow star was pierced, the environment of heaven and earth has changed since then, and the vitality has been continuously lost. This is why the number of immortals has been decreasing since ancient times, so that Thirty thousand years ago, there were only the last thirteen immortals left on the ancient star."

"It is not only the inheritance of immortality that is affected, but also the inheritance of martial arts that was very prosperous in ancient times has also been interrupted, and the six veins of my Gu family. Fewer and fewer, the last super-body owner was the ancestor Gu Hao who brought us to the Fairy Continent 30,000 years ago."

"Since the ancestors and the thirteen immortals, the environment of Canghuang Ancient Star has become even worse. So far, no overlords and immortals have been born."

After the initial shock, Gu Chen became calm and murmured. "I heard that the ancestor and the thirteen immortals disappeared shortly after they migrated to the Fairy Continent, and I saw an ancestor with a super-heavy body outside the eyes of the Tiankeng, it seems that that person is the ancestor Gu Hao."

Gu Lianyue nodded heavily, "I'm afraid that's right, do you know why the ancestors and the thirteen immortals entered the Tiankeng Earth Eye?"

Gu Chen shook his head.

"Since the ancient catastrophe, the pale yellow ancient star has become no longer suitable for cultivation. The monks of all ages have thought of countless ways to change this situation, and there are mainly two methods."

"The first one is that when the catastrophe came, the ancient continent fell apart, and the ancient immortals died, and the prosperous civilization was interrupted. It is said that the wreckage of the ancient continent is in the center of the earth, and there is still a strong inheritance there, so many later When monks have no hope of breaking through, they will choose to enter the Tiankeng, hoping to find the treasures left by the immortals, and then break through to become immortals."

Gu Chen suddenly realized, this explains why so many heroes in the past dynasties chose to enter the Tiankeng to gamble on their chances.

"Secondly, people are looking to the distant universe. Since the pale yellow ancient star is no longer suitable for cultivation, many monks hope to leave the ancient star and enter the universe to find another ancient life star."

"In ancient times, people knew about the vast star field beyond the ancient Canghuang star, so they chose this method at the first time. They just didn't expect that after the catastrophe, Tianxu appeared in the sky above the ancient Canghuang star. It is full of nine-day storms, and no one can surpass it."

"The road to the sky is interrupted, so all monks who want to seek further can only put their hopes in the eyes of Tiankeng."

"No, if it was impossible to enter the universe because of Tianxu, then 30,000 years ago..."

Gu Chen remembered the event of the gods descending 30,000 years ago.

"It seems that you have already figured it out. Thirty thousand years ago, the gods descended on the Canghuang ancient star in order to find a certain treasure. My ancestors of the Gu family and various alliances worked hard to eliminate them, but it also led to the destruction of the Kunlun Continent. Once, it is even impossible to completely wipe out the relics left by the gods."

"After going through that war, the ancestor Gu Hao and the thirteen immortals realized the vastness of the universe and felt that they were small and weak."

"According to the warnings of the gods before they died, they are only the vanguard. In order to find such treasures, sooner or later more masters will come to the Canghuang ancient star."

Gu Chen's heart was awe-inspiring, and he couldn't help touching his abdomen. Could the mother root of all things in the dantian be such a treasure?

"Because of the threat of the gods before death, and the ancestors and the thirteen immortals also want to seek a breakthrough, they are determined to leave the ancient star. They want to cross the universe and seek a higher realm, so as to protect the ancient star Bullied by outsiders."

"Since the gods can pass through the Tianxu and descend to the Sky Burial Continent, the ancestors thought they could do the same, so they tried to ascend to the sky."

"But the result is that they failed. Like the ancestors of the past, the Tianxu is basically insurmountable."

Gu Chen blurted out, "So they also focused on the Tiankeng?"

Gu Lianyue nodded, "The ancestors and the thirteen immortals entered the Tiankeng not long after they moved to the Fairy Continent, and they never came back."

"Since then, the vitality of the Canghuang ancient star seems to have been exhausted, and no hegemony or immortal has ever been born."

"Over the past 30,000 years, whether it is my Gu family or the Thirteen Immortals, many ancestors have entered the Tiankeng Earth Eye one after another, either to prolong their lifespan, or to seek a breakthrough in the realm."

"Back then, your Xuanzu and great-grandfathers also led a large number of elites from the clan into the Tiankeng for the same reason, but they also failed in the end."
