The main hall is as thick as a mountain, like a mountain range, so that people can't rise to the slightest blasphemy, Gu Zichen stood outside the main hall, his eyes were full of unapproachable hesitation, as if he didn't dare to approach it, and at the same time mixed with a sense of homesickness. Pen & Fun & Pavilion www.biquge.info

The main hall was suddenly integrated, only in the place directly opposite Gu Zichen, at the two tightly fitting bronze gates, there was a path to enter, but on the bronze gate of the path, it was locked by a bronze ancient lock, as if the path was completely sealed.

Gu Zichen stepped forward, just a few dozen meters away, five or six hundred meters away from the main hall, suddenly, the steps that were originally taken easily seemed to have touched an invisible barrier, and Gu Zichen's body seemed to be pushed backwards by an invisible force.

Gu Zichen's complexion changed greatly, and the mana at the peak of the late stage of the Condensation Realm rose up, colliding with the huge force that was pushing the waves.

"Bang!"

What made Gu Zichen's heart frightened, the mana that Gu Zichen had pushed before seemed to be of no use, and he was directly hit by this huge force and retreated five or six thousand meters backwards before he could stabilize his body, but a mouthful of blood came out of the corner of his mouth, and he was bruised under the blow.

"How is that possible?"

Gu Zichen's heart was shocked beyond measure, Gu Zichen had already felt that this huge force was just the rebound force that he had just stepped away, and it was relatively weak compared to the invisible formation. If he attacked it, it would be difficult for Gu Zichen to imagine how strong the force of the rebound would be, attacking and killing him.

"Click, click, click......"

Just when Gu Zichen was at a loss, the sound of the door lock opening suddenly came into Gu Zichen's ears, Gu Zichen suddenly looked up, and saw the bronze key that had been speeding away before, as if it was the secret key of the main hall of the True Treasure Palace, and it looked like the ancient door lock was easily opened.

It seemed to be an illusion, at the same time that the door lock was opened, Gu Zichen suddenly couldn't perceive a trace of the previously invisible formation, Gu Zichen walked towards the True Treasure Hall with a tentative look on his face.

Everything went smoothly, Gu Zichen came to the bronze gate of the True Treasure Hall safely, the bronze key was like a naughty boy, happily flying around Gu Zichen, happy as if welcoming Gu Zichen, the master.

Gu Zichen lovingly touched the bronze key, with curiosity and confusion, stretched out his hands and pushed towards the two gates, a heavy sound sounded, and the two gates slowly opened, revealing the true face of the True Treasure Hall.

Gu Zichen hurriedly looked at it, his face was shocked at first, but in an instant, with a look of ecstasy, he kept turning his head, as if he was in disbelief, and kept visiting.

"What's going on, how can there be so many monsters on display here?"

But in the main hall, there are huge columns with waist thickness standing, which looks empty and boundless, with the size of a hundred acres, and the appearance of endless.

The gap between the two pillars of the main hall is wrapped in a formation of different colors, and within the formation, there are huge demon beasts lying down, the eyes of the demon beasts are closed, and they all look like they are dying, but they all have a breath of breath left, and they are not dead.

Gu Zichen seemed to be involuntarily, stepping forward and looking at the demon beast closest to him, but seeing that this demon beast looked like a pig, its limbs had long sharp claws, with sharp serrations, and it was very fierce.

"Tanuki!"

Gu Zichen's eyes shrank and muttered to himself. Tanuki power is a relatively ancient demon beast, although the combat power is not strong, but it is tens of thousands of years away from now, and it has become extinct.

"It turned out to be the early stage realm of the Condensation Realm, what a big deal!"

Gu Zichen carefully probed, his complexion changed, and he seemed to only have a long raccoon power, and his strength was at the level of a high-level cultivator in the Condensing Realm.

"Gu Eagle!"

Gu Zichen crossed the raccoon force and looked at the second demon beast, his face changed greatly, and he almost blurted out.

But seeing the demon beast wrapped in the second formation, it looks like a bird but not a bird, like a leopard and not a leopard, with a single horn on its head, a green face and fangs, four hooves, and a long tail, which looks extremely vicious, and it is also a fierce demon beast ten thousand years ago.

"It has actually reached the level of a Great Cultivator of the Transformation God Realm!" Gu Zichen looked at it carefully, his face was shocked, and the Gu Eagle exuded the power of the Great Cultivator of the Transformation God Realm, and through the formation, it was all transmitted into Gu Zichen's eyes.

Gu Zichen stood in front of the Gu Eagle for more than ten minutes, before he walked away, looking at the formations one by one, his face was shocked from time to time, and in the end, the original look of surprise instantly turned into surprise, wandering back and forth in the empty hall, as if he was trying his best to suppress the surprise in his heart.

At this moment, the bronze key, which had been floating beside Gu Zichen, suddenly stabbed Gu Zichen's face with the tip of the key, with a naughty meaning.

Gu Zichen's face was cold, he reacted from the surprise just now, and hurriedly looked at the bronze key, but saw the bronze key slash through a streamer, and suddenly flew to the deepest part of the main hall, came to a wall, and touched a hall wall with the body of the key, as if guiding Gu Zichen.

Gu Zichen's face moved slightly, and he knocked on the wall touched by the key with his hand, making a thumping sound, and the inside seemed to be empty.

"There's a trap!"

Gu Zichen muttered to himself, looked up and looked around, just in time to see the bronze key flying above his right side, next to a bronze ancient lamp.

Gu Zichen nodded, comprehended, stretched out his right hand and turned the bronze ancient lamp, there was a click, and the wall that the key had touched slowly opened, revealing a hole in a square foot.

Inside the hollow, an unusually simple blue-black delicate box sat peacefully inside. Gu Zichen's eyes lit up, his divine sense penetrated inward, and he found that there was no danger.

Hurriedly rolled up his mana, stretched the delicate box outward, and floated steadily in front of Gu Zichen's eyes. There is also an ancient lock that is only half the size of a fist, locking the chest inside.

Gu Zichen's face was puzzled, and he nodded to the bronze key floating in front of him, the bronze key's body lit up, emitting a bronze light, which shot directly on the ancient lock, and the ancient lock automatically opened and fell to the ground.

Gu Zichen's face was stunned, but he didn't have any doubts, and immediately reached out to open the delicate small box, but saw that inside the small box, there was a scroll of books lying peacefully, the books were facing up, and the three dark red fonts were like blood, which made Gu Zichen's heart shrink, and he shouted almost in disbelief:

"Rong Yuan Gong?"

Gu Zichen had previously obtained the exercises of Rongyuan Gong to the realm of Condensing God Realm in the Golden Immortal Secret Realm, and now he was worried about the follow-up exercises, and he actually discovered the Rongyuan Gong cultivation exercises again in this True Treasure Palace, and everything showed that these phenomena were too incredible.
