Castle of Black Iron

Zhang Tie had seen the world and mountains of jewelry; however, he was still stunned by this world being composed of numerous huge crystals.

Usually, Zhang Tie could at most see crystals which were a few tons in weight and a few meters in length. However, each crystal at present was like a skyscraper.

The crisscrossed crystals which were hundreds of meters in length and dozens of meters in thickness were like bridges in the underground space. The entire ground had been covered with finer crystals which were growing vigorously like weeds on the prairie. As a result, Zhang Tie felt like entering a paradise.

Compared to such huge crystals, Zhang Tie felt being dwarfed and turned as small as an ant. What a wonderful crystal world!

This world was filled with colorful huge crystals. Each crystal contained a pyramid-shaped shadow. It was the brilliance reflected by crystals that made this space resplendent. Additionally, the strong high-intensity energy carried by those crystals filled each nook and corner of this underground space.

Any piece of crystal which was heavier than 3 kg was called crystal generator as it could make people energetic and do a favor to people’s cultivation. By contrast, this place was more like a crystal nuclear plant rather than a crystal generator. Anyone below knight who cultivated in this place would undoubtedly light their surging points in high efficiency. This was a holy land for cultivation, which was dreamed by everyone below knight.

Zhang Tie almost stopped moving at the sight of such a dreamland. He was really shocked by this scene, not because of his greed, but because of his reverence to the marvel in the great nature.

Such a marvel might take a few billions of years. How magnificent it was!

Each crystal here might drive people mad and would worth a lot if it was taken out of here. However, Zhang Tie thought that very few space-teleportation equipment could hold those huge crystals besides his Castle of Black Iron. Additionally, each of those crystals would weigh tens of thousands of tons. They couldn’t be taken away from here unless being broken in parts.

“Hurry…the demon knight is catching up with us…”

Yan Feiqing’s body turned increasingly hotter. When she spoke, she started to pant while her snow-white face turned as red as the morning glow as if she was drunk.

“Could that demon knight find us here?” Zhang Tie asked out of curiosity as he felt that it was difficult for that heavenly demon knight to break through those ruined watercourses, not to mention the maze-like bypasses.

In case of commoners, money was not almighty; however, money worked in many cases. Similarly, as for knight, equipment was not almighty; however, equipment worked in many cases. For instance, those alchemist’s bombs in his portable space-teleportation equipment helped them a lot today. Without those alchemist’s bombs, he might have to expose his trump card today.

“When we fought just now, it has already positioned me by its spiritual energy. That’s the exclusive ability of heavenly demon knight. Within 7 days, he could sense my precise location within thousands of miles. As the crystals in this hole have strong energy, they could disrupt its spiritual energy for the time being. As a result, it could only roughly judge the location from where we disappeared. Before it comes here and sees us, it’s the last chance for us to escape away…” The female shadow knight who was pretty powerful just now oozed over her forehead when she spoke at this moment. Additionally, her body looked ramshackle as if she was going to fall off at any time.

“Spiritual positioning possessed exclusively by heavenly demon knights…” Zhang Tie was startled. ‘That’s simply a portable tracing feather. Damn, it seems that we’re not over yet.’ “Ahh, it seems that you’ve been here before. Where’re we going then?”

“There’s a tunnel right in front of us. There’s an underground chasm inside there. After entering the chasm, we will enter a magma sea. A location at the bottom of the magma sea could completely isolate the spiritual perception of the demon knight…”

“What about you now? Can your protective battle qi bear it? If you need, I’ve got some medicament…”

After seeing Yan Feiqing nodding hardly and taking out a vial of blue medicament from her portable space-teleportation equipment and drinking it up, Zhang Tie instantly pulled her towards the destination.

After drinking up that vial of blue medicament, Yan Feiqing’s body temperature slowly recovered like having been poured with a basin of cold water. However, Zhang Tie felt that she was turning weaker as her limbs turned soft as if she had lost her strength completely.

In this case, no matter how magnificent this underground crystal cave was, Zhang Tie didn’t have time to appreciate it; instead, he could only escape at first.

“You’re so familiar with this place. Have you been here before?” Zhang Tie asked Yan Feiqing as he surged forward.

Yan Feiqing remained silent. Zhang Tie felt so embarrassed that he could only touch his nose quietly.

The underground crystal cave was so large that they had not flown out of it after 120 miles’ distance according to Yan Feiqing’s guidance. After making so many turns, he finally caught sight of a calm magma sea. Being reflected by the crystals, the tumbling glow of the magma sea looked more splendid in this underground space.

After feeling that Yan Feiqing had already released her protective battle qi which meant that he could enter it, Zhang Tie immediately released his protective battle qi and dove into this magma sea together with Yan Feiqing.

“Right, 9 o’clock…”

Like before, Yan Feiqing kept guiding Zhang Tie in the magma sea.

Although their speed in magma sea couldn’t match that in water, they could also move above 300 m per second. After moving forward for over 20 minutes, they heard a faint earthquake and noise from the crystal cave behind them. Zhang Tie instantly knew that the heavenly iron-armored demon knight had already caught up with them. As it had lost its target, it was losing temper in the crystal cave…

“Did the iron-armored demon lose its target?”

“Yes…”

“Are we still in that huge crystal cave?”

Yan Feiqing nodded. Zhang Tie then became reassured. In this case, unless that heavenly demon knight also had lotus-flower eyes, it would be as difficult as looking for a needle in a bottle of hay for it to find the two people in the magma sea.

Except for Zhang Tie, the other knights couldn’t see anything in the magma sea; instead, they could only sense it based on their powerful knight’s consciousness. By contrast, Zhang Tie could see clearly those black mountain ranges at the bottom of the magma sea.

Those mountain ranges were not composed of rocks but high-purity precious gold ores that had been deposited for hundreds of millions of years. Like those huge crystals, these gold ores would also worth a lot when they were carried to the surface of the earth. However, in the underground space, they just piled up like mountains and accepted the baptism of ages quietly. Unless another earth-shaking geological movement happened in this world, these items would lie in this underground magma sea forever quietly.

After a short while, the faint rock and noise gradually faded away, which meant that that heavenly demon knight had chosen the wrong way to chase after them. On the way towards this magma sea, Zhang Tie had observed the surrounding environment and found hundreds of bypasses in the crystal space. In this case, it would be impossible for that heavenly demon knight to position them. It could only try its fortune.

Zhang Tie was curious about the location which could isolate the spiritual perception of the heavenly demon knight. If that heavenly demon knight just stayed somewhere in the crystal cave in the following 7 days, it would be troublesome. Zhang Tie might be able to stay in the magma sea for 7 days; however, what about Yan Feiqing who was already injured?

Yan Feiqing was in a volatile state as her body turned cold and hot now and then. Therefore, Zhang Tie kept a close eye on her while moving forward in the magma sea and preparing to give her a favor at any time. If her protective battle qi collapsed, she would instantly turn into ashes facing such a great stress and high temperature.

Nevertheless, when Zhang Tie was wondering which thing attracted Yan Feiqing here from far away, he was dumbfounded.

Zhang Tie’s lotus-flower eyes caught sight of one thing that would be the last thing in his mind that could exist here.

Right among those gold mountain ranges, Zhang Tie caught sight of a huge pyramid, which was erecting at the bottom of the magma sea quietly and profoundly.

Compared to that pyramid that Zhang Tie saw before, this one was higher as it was higher than 10,000 m. The entire pyramid was a huge crystal which was as red as the surrounding magma sea. By contrast, it was another tower of time…
