Soon Sun Fengzhao also confirmed his conjecture with practical actions: at this moment, he was walking in surprise along a spiraling stone staircase, step by step to the depths of the low cave, his face was full of surprise.

Not long after entering this cave that he smashed open at will, there were endless stone stairs in front of him, and the black soil that looked back at the entrance of the cave top neatly collapsed, didn't it hang upside down on the other side of the cave roof!

This proves Sun Fengzhao's conjecture that this gold brick is the key for the ancient monks to open the upper and lower caves.

In fact, after Sun Fengzhao entered the cave, he found that the top of the cave in the shape of an arch above his head was dotted with a number of scattered glowing crystal clear stones, and those stones were like moonstones on the wall of the cave roof, exuding bright light. But Sun Fengzhao quickly confirmed that it was not a moonstone, but a kind of immortal cultivation material that he didn't know.

Sun Fengzhao frowned, subconsciously looked around, and suddenly remembered something. With one hand on the storage bag, a piece of rune paper full of lines appeared in Sun Fengzhao's hand. This is exactly the picture that Sun Fengzhao got in the passage of the remains.

He took a closer look at the map, and then looked at the nearby environment and location. There was a hint of surprise on his face. The location of this place is like a place marked in the map, and Sun Fengzhao only then understood the view of this map, it turns out that the drawings drawn on this plane, this layer of lines, is the meaning of the next layer.

Sun Fengzhao has been equal to two floors down so far, this picture shows that this underground world is divided into four layers, and the place where Sun Fengzhao is now is not from the central layer in the picture is a shortcut, as if you will not go too far along here, you can reach the central layer. Out of this floor, go down two floors. You should be able to reach a thick point on the central layer marked in the diagram.

Looking at the thick dot marks in the picture, Sun Fengzhao groaned. He was not interested in exploring such a deep area, he was already very satisfied with the current gains, and he only wanted to get out of this ancient battlefield as soon as possible and return to Fengzhao to watch his leisurely life. Even if there were many ancient treasures in the central area, or good things left by ancient monks, Sun Fengzhao was not very tempted.

Sun Fengzhao, who now had the Geng Silver Dragon Sword, was planning to return to the temple gate where he entered, use the extremely sharp Geng Silver Dragon Sword to separate the damn temple door, and then leave this underground ruin.

But he didn't think about it, just when Sun Fengzhao dispelled the idea of going deeper, stood on the steps down and glanced at the red light prohibition below, and was about to turn around and leave, as soon as he turned around, he heard a "bang", and a burst of spiritual power fluctuations that obviously sent to the top of the cave were those crystal clear luminous stones, causing the pile of black soil that was originally hanging quietly on the side of the cave roof, and with a bang, it turned back to the entrance of the cave and returned to its original position, blocking Sun Fengzhao's retreat.

"Hey, why is this happening?"

In Sun Fengzhao's protests, even if Sun Fengzhao flew over as fast as he could, he still couldn't catch up with the closure of the cave.

Sun Fengzhao didn't have time to figure out what kind of material the black soil mound was just now, and now he understands that although the prohibition here is rough, it is all made by using the upper-level genius earth treasure materials and cooperating with the mechanism science. It's simple, but it's easy to use and very effective. Moreover, it seems that these glowing stones were not inlaid on the roof of the cave only for lighting, but turned out to be the source of power for the prohibition of import and export.

After so many years, these luminous stones are still working, I don't know how many times larger than the spiritual stones that work in the immortal cultivation realm today, the spiritual power reserves?

Sun Fengzhao was locked in the cave, but he was not in a hurry, he brought the gold brick key in with the storage box anyway.

Sun Fengzhao, who took out the gold brick, smashed it hard. In Sun Fengzhao's imagination, it can be used as a key to get in, and it can also be used as a key to get out.

But this time Sun Fengzhao was wrong again, when the gold brick flew close to the top of the cave opened by the black soil mound, it was the luminous stone embedded in the top of the cave that flew towards the entrance with a burst of spiritual power fluctuations, and with a bang, it actually rebounded the gold brick that Sun Fengzhao sacrificed, looking like the key was wrong and could not be opened.

Then Sun Fengzhao used the Gengyin dragon-shaped sword again, wanting to rely on its sharpness to forcibly cut this exit. However, the Gengyin Dragon-shaped Sword suffered the same treatment as the Golden Brick Ancient Treasure, and was rebounded by the spiritual power fluctuations like a conditioned reflex. It's just that those glowing stones, when the ancient treasure blocking Sun Fengzhao broke the ban, the brightness dimmed a little. Sun Fengzhao became more and more anxious and went out, but he didn't notice it.

All he knew was that there were some forbidden protections made of glowing stones, and it seemed that it would be difficult to reopen this portal without the right key. Sun Fengzhao also tried to pry off a few of those glowing stones with a magic weapon to break the prohibition here, but all failed.

"Hell, are all the doors here like this?

Hated and discouraged, Sun Fengzhao sat on the steps for a while. It suddenly occurred to me that since the key to open and enter this level could be found on the upper floor, the key to return was on this floor.

"Then go down and find out!"

Sun Fengzhao, who had regained hope, started to explore downward again, but after walking for a full cup of tea, there was still no sign of the end.

Sun Fengzhao's curiosity was aroused, could it be that the exploration he had just made just now was wrong, and the place where the ground was wrapped in red light was actually built in such a low place?

Holding the doubts in his heart, Sun Fengzhao calmed down and walked along the steps, going deeper little by little unhurriedly.

After walking more than 100 steps up, Sun Fengzhao finally saw the rich flowing red light. Immediately, he sped up his pace, and sure enough, after turning a corner, an ordinary square entrance was in front of him.

Looking faintly along the entrance, the scene inside made Sun Fengzhao's expression move, and he hurriedly strode down.

Just after this entrance, another temple door appeared, but this one was open. Next to it is a huge sign more than one person high, the brand is obviously the texture of the materials used by immortal cultivators, but I don't know why, there is no trace of time on it, and it still looks like a streamer.

And this brand, there are only a few crooked text symbols, which are obviously ancient immortal cultivation text symbols that Sun Fengzhao can't understand.

Sun Fengzhao didn't bother to study these characters, anyway, he saw too much. I just rubbed it down and prepared to go back and hand it over to my master Lu Wantian to study slowly.

But after getting closer to the palace gate, it showed its tall and majestic, and Sun Fengzhao estimated that it was at least three or four times the size of the palace gate he had seen before.

After entering the unclosed temple gate, there is a semicircular arch, two feet high, and a layer of red light curtain seals the entrance and exit of the arch.

Sun Fengzhao did not rush into the arch and the red forbidden shield, but carefully studied the environment around him, and only after making sure that it was okay and dangerous, did he start.

Although the red curtain displayed by this arch is not large, the astonishing fluctuations of spiritual power emitted within it are unfathomable, and a faint white fluorescence envelops it. It seems that this place has been laid out by the ancient monks with an extremely powerful forbidden formation.

Sun Fengzhao, who had been observing for a long time, finally moved, and he first released his divine sense again, wanting to penetrate the forbidden layer to see the situation inside. But soon Sun Fengzhao gave up this way of exploration, because Sun Fengzhao, who had always boasted of his powerful divine sense, released his divine sense, and as soon as his divine consciousness encountered that layer of prohibition, Sun Fengzhao felt that his heart was shaking, dizzy, and daunting!

After staring at the discomfort for a while, Sun Fengzhao still retracted his divine consciousness without finding anything.

Then Sun Fengzhao walked directly to the forbidden layer without hesitation. He slowly stepped through the archway, and walked towards the forbidden place step by step.

When I got to the door, I looked at the forbidden light curtain. Sun Fengzhao tilted his head slightly and thought about it, the silver light flashed in his hand, and a silver sword light that was only a few feet long appeared in his hand. This is the Gengyin dragon-shaped magic sword that Sun Fengzhao has just obtained from the ebony storage box.

Since the gold brick is the key to open the entrance to the next layer, then this magic sword may also be the key to open this forbidden layer?

This time, Sun Fengzhao was right, he lightly injected a little mana into the dragon-shaped magic sword, and then lightly touched it with his fingers, and the silver sword light gently poked at the forbidden light curtain.

The ripples rippled, and the silver sword light was easily inserted into it, without the slightest hindrance.

This situation made Sun Fengzhao a little surprised, but also a little expected. Immediately, he put away the silver sword light, and then stretched his arm into it in the same way, and it passed the same, and there was no discomfort at all when he stretched it in and out, but it was a little cool, as if it was wrapped in a mass of liquid.

Sun Fengzhao's figure jumped forward without hesitation, and the person disappeared behind the forbidden light curtain through the forbidden light curtain.

But after passing through the arch, Sun Fengzhao, who was standing in front of the wider cave at the other end, was stunned again.

In the huge cave at the other end, Sun Fengzhao was located on a platform about one person high, and on both sides was a circle of circular steps down. And down there are rows of amazing things, which seem to be large or small transparent covers, oh no, they should be transparent water pattern masks, like upside-down bowls, and there are independent platforms like stone platforms on the base.

Sun Fengzhao silently walked into the cave at this end from the circular steps, and found that the space of each platform was not large, except for a spherical water pattern mask of different volumes on the top that was fluctuating regularly, there were several strange characters of different numbers engraved on the corner of the platform on each platform, and there were tube-like things connected to each other between each platform.

Naturally, these characters were all ancient characters that Sun Feng couldn't understand, and in front of the first water-patterned light mask about a few feet high, there were five or six strangely shaped giant eggs floating quietly in it through the dazzling light that exuded a blue softness.
