The Nine Dragon Wall looks smooth, but when viewed with divine sense, it reveals numerous cracks, resembling a pile of massive, grayish-white rocks.
Zhang Ling suddenly waved his hand, a flash of cyan light appearing, and a sword light struck the wall before him. A muffled sound echoed, leaving only a long, white mark.
He couldn't help but inhale sharply. This Nine Dragon Wall had been here for countless years, yet it remained so sturdy, surely due to some kind of formation or restriction. At the same time, he beckoned with one hand, and several stones from the ground flew towards him.
These stones had fallen from the Nine Dragon Wall and were very irregular, looking like naturally formed rocks.
However, Zhang Ling discovered that these rocks were grayish-green on the outside, but the inside was divided into several layers, as if different rocks were compressed together.
“Oh, this layer seems to be compressed black ironwood, and this layer is cast from gold-copper rock.” He examined these stones for a while, recognizing some of the materials in the several layers inside.
Black ironwood and gold-copper rock are tough materials for refining tools, commonly found in the cultivation world. If this entire Nine Dragon Wall was cast with such mixed stones, it would be unimaginable.
The Nine Dragon Wall is thousands of feet high, forming a complete circle, encompassing a vast area. The materials alone would be an unimaginable expense.
Zhang Ling stood below, examining the Nine Dragon Wall for a while, then began searching for the city gate along the way. There was also a Nine Dragon City built here.
To call it a celestial city isn't entirely accurate. Nine Dragon City isn't like ordinary celestial cities; it's built on this Nine Dragon Wall. There are a total of nine city gates, corresponding perfectly to the nine major spiritual veins of Tianheng Mountain, Flying Cloud Valley, and others.
Flying around the Nine Dragon Wall for a while, he heard the loud sound of water. The sound was very loud, like a waterfall.
Sure enough, before long, he saw a huge gap in the Nine Dragon Wall above, and a silver stream of water fell from the sky, forming a wide river below that flowed into the distance.
The water flow was hundreds of feet wide and five or six hundred feet high, making it look extremely shocking. Suddenly, several black shadows tumbled in the water and fell into the water below.
Zhang Ling focused his eyes and saw that they were several black strange fish covered with bumps.
At the same time, a cooing sound came from above, and a blue shadow swooped down, swallowing several black strange fish with its big mouth. This was a two-丈 large flying bird covered with blue feathers.
The blue bird flapped its wings and hovered in the air for a moment, then flew directly towards him.
Zhang Ling snorted lightly, and a flying sword was released. The sword light flashed and cut the blue bird into several pieces.
The blue bird cried out, and its broken body fell down. This was just a fourth-order demon bird and posed no threat to him.
Zhang Ling didn't stay in place and flew directly upwards. Soon, he saw a stone gate built on the Nine Dragon Wall.
Water vapor rose from below the stone gate, and a huge black shadow was hidden in the water mist. On closer inspection, it turned out to be a huge dragon head, of course, just a dragon head statue carved from a huge stone.
Some cyan-black spiritual patterns also appeared on the surrounding stone walls. It seemed to be some kind of formation pattern, very regular, like the scales on a giant dragon.
The stone dragon statue was lifelike, raising its head and spitting water. The dragon's mouth was the source of the waterfall, and the water flowed down from this place.
The stone gate above the dragon head was also engraved with spiritual patterns, turning into a layer of golden spiritual light covering the stone gate. This stone gate was also very large, arched at the top and vertical at the bottom, more than ten 丈 high.
Zhang Ling came to the stone gate and took out the Tianyuan Token. He cast a spell on it, and a layer of five-colored spiritual light appeared on the Tianyuan Token. With a flash, he passed through the golden light curtain without any hindrance. Inside was a long, deep passage, leading to who knows where.
He looked at the place marked with the teleportation array on the Tianyuan Token and directly searched along the passage.
……
Inside a dark passage, a loud bang came.
Zhang Ling opened a stone room and entered. There were many things inside, but it was a mess. Wooden shelves, bottles, jars, and other things were scattered all over the floor. After checking for a while, he left the stone room without finding anything useful.
This was the seventh stone room he had checked.
After entering this place, a stone room would be found every so often. Not long ago, Zhang Ling found a small piece of Tiangang silver in the third stone room, which made him interested and started checking these stone rooms.
Tiangang silver, like the Jinyuan stone he had previously mixed into his flying sword, was a top-level treasure refining material. Moreover, the effect was much better than Jinyuan stone. If flying swords, flying knives, and other magic weapons could be mixed with some Tiangang silver, their power could be greatly increased.
The Tiangang silver he just found was only the size of a thumb, probably not enough to mix into a flying sword. But this was just an unexpected gain, and he didn't have much hope of finding other Tiangang silver.
That piece of Tiangang silver might just be a treasure refining material left behind by ancient cultivators.
Continuing forward, after a while, Zhang Ling saw a light gate. Holding the Tianyuan Token in his hand, he easily passed through the light gate. The environment behind was exactly the same, another long tunnel.
The place he was in now was actually inside the Nine Dragon Wall, divided into several layers. Apart from finding a stone room every so often, there were no other discoveries.
These stone rooms were mostly the cave dwellings of ancient cultivators, but they were basically empty and yielded nothing.
The light gate was the passage to the upper and lower layers. There was only one mark on the Nine Dragon Wall for the teleportation array he was looking for, located on the bottom layer.
The long, dark tunnel made people dizzy, like a maze. Fortunately, there were no other dangers in entering this place, just a long journey.
As for using earth escape techniques or other methods to travel, Zhang Ling tried it as soon as he came in, but it didn't work. This Nine Dragon Wall has powerful restrictions, and escape techniques cannot be used here. He could only walk along this passage.
In this way, two hours passed, and he finally reached the bottom layer.
The passage on the bottom layer was wider. As soon as he entered this place, everything in front of him was a vast expanse of white.
Zhang Ling quickly released his divine sense and checked his surroundings. He found that the white mist was just ordinary water vapor, which had little effect on cultivators. He was about to move forward again when his face suddenly darkened and he shouted in a low voice.
“Which fellow Taoist is here?”
Zhang Ling stared at a place in the passage with an icy expression. A cyan light flashed in his hand, and two flying swords appeared beside him, looking like he was facing a formidable enemy.
“Haha, it turns out to be Fellow Taoist Zhang.”
A pleasant voice came from that direction. Hearing this voice, he felt a sense of familiarity, but he couldn't remember where he had heard it before.
