Castle of Black Iron

Kneeling on the ground, Zhang Tie panted for quite a while. After that, he wiped off the blood at his mouth corners and slowly picked himself up. Then, he started to look around this bizarre place.

There was a huge palace behind the archway. This palace was higher than 200 m. It was so magnificent that it didn’t seem like being built by humans. Many odd runes were flowing over the walls and the ground faintly. The ground of the palace was as clean as a mirror, which could clearly reflect Zhang Tie’s shadow. Besides Zhang Tie, nobody else was in the palace. There was not even any decoration inside the palace. There were only 5 closed gates at the end of the palace which looked such mysterious and profound.

Based on his great resilience, Zhang Tie had almost recovered his wounds.

This palace should be inside Buzhou Mountain.

Zhang Tie felt an irresistible power inside this palace, which drew him to the ground. As a result, he couldn’t fly in the palace. However, his space-teleportation equipment was still available here because of the balanced time-space force.

‘It might be the place where Tang Mei could come out according to her descrpition.’

After taking a look at the 5 gates at the end of the palace, Zhang Tie ran his spiritual energy. The huge black tower in his hand instantly shrunk and finally became a 15 cm-higher mini-tower before flying above Zhang Tie’s head and rotating over there. Closely after that, Zhang Tie pointed at his central forehead by finger. The mysterious portal accessing to Castle of Black Iron in his mind immediately reflected a light&shade in front of him. Through the light&shade, the Motian Mirror that he once saw in Emperor NvWa’s Palace immediately appeared in this palace. Closely after that, the mirror started to undulate like a ripple. Then, Tang Mei in white skirt walked out of Motian Mirror.

“Brother, thank you for helping me leave Emperor NvWa City and visit another world…” Tang Mei appreciated Zhang Tie as she watched him and giggled.

“Ha, hopefully, you don’t regret!” Zhang Tie said as the light&shade disappeared. Closely after that, Motian Mirror disappeared too.

“I’m just trying my best. Brother, I believe that you don’t want to see me die soon!” Tang Mei said with wide eyes as she started to look around this colossal palace like a little girl who had just got off the tourist coach.

As for a person who would live in Emperor NvWa City for the rest of her life, it was really a rare experience for her to visit a place outside Emperor NvWa City.

Zhang Tie shook his head silently with a bitter smile.

Besides acquiring great power from Emperor NvWa City, Tang Mei’s active space was limited. As Emperor NvWa, Tang Mei couldn’t leave Emperor NvWa City in ordinary days. However, with the help of Zhang Tie’s Castle of Black Iron, she could. Meanwhile, she had determined to make a new trial. If Zhang Tie couldn’t have Castle of Black Iron integrate with the space ball of Motian Realm, even though Tang Mei could leave here alive and return to Emperor NvWa City in the end, she could only live 3 more years at most. 3 years later, she would perish. Neither would any new Emperor NvWa appear in Emperor NvWa’s Palace.

Even Zhang Tie admired this maiden’s strong will. To be honest, even Zhang Tie was not confident enough to integrate the Castle of Black Iron with the space ball of Motian Realm until now; because he would encounter many obstacles in the process. However, Tang Mei put all the stakes on him. Even Zhang Tie didn’t know why Tang Mei had such confidence in him.

“Where are we going?” Zhang Tie asked Tang Mei.

Nobody in Motian Realm knew the inside situation of Buzhou Mountain better than Tang Mei, humans or demons.

“Brother, as you’ve just passed so many obstacles, don’t you want to know the surprise behind those gates?” Tang Mei asked as she pointed at the 5 gates at the end of the palace.

Zhang Tie knew that Tang Mei wouldn’t do harm to him. Therefore, he instantly ran towards the 5 gates.

Although Zhang Tie couldn’t fly, he could also move rapidly on the ground.

The one in the middle of the 5 gates looked a bit bigger. It was higher than 100 m and could almost match the other archways outside. By contrast, the 4 gates on its two sides were relatively smaller. Meanwhile, there was an odd rune on the top of the four gates respectively.

Zhang Tie came straight to the left-most gate as he found that the rune on the top of the gate was like a seal character “fire”. Zhang Tie looked up at it for a short while. Closely after that, he put his hands on the thick gate and lightly pushed open a gap.

A strong qi of fire element instantly surged out of the gate. Being stimulated by it, Zhang Tie couldn’t help making a sneeze.

‘How could there be such strong qi of fire element?’ Zhang Tie wondered. He then pushed open the gate completely out of curiosity. Closely after that, he was submerged in a red glow.

It was a colossal space behind the gate. At the dome of the space, there was a huge overturned sacrificial altar. There were various bizarre runes around the sacrificial altar. Additionally, four huge pillars drooped down in different directions, forming a huge claw, which caught a “huge dough” which was wriggling and giving out the glow.

The “huge dough” tinted the entire space red. The strong qi of fire element came from the wriggling “huge dough”.

When Zhang Tie came to the front of the “huge dough”, he slightly closed his eyes and reached his spiritual energy into that “huge dough”. In an instant, he was startled by what he saw.

‘F*ck!’

Zhang Tie became dumbfounded as he almost jumped up.

The “huge dough” was connecting to the Elements Realm from inside. The situation facing the Elements Realm inside the “huge dough” almost toppled over Zhang Tie’s recognition about Elements Realm. The elements inside the Elements Realm were not element crystals that were flying in the space like fireflies and meteors; instead, it was absolutely a mountain of the purest fire element.

Standing in the Elements Realm, the mountain was giving out a brilliant glow magnificently as if it could never be exhausted.

What Zhang Ties’ spiritual energy to this mountain of fire element crystals was what a mouse to a huge granary. Any cultivator would be shocked by this scene in an indescribable way.

Unconsciously, Zhang Tie was going to drool.

The mountain of fire element crystals was like a huge treasure house of element crystals in the Elements Realm whose fire element crystals would never be exhausted. If one cultivated in such an environment, he only needed to sniff the strong qi of fire element instead of taking any element crystals.

“Is it the place for cultivation inside Buzhou Mountain?” Zhang Tie asked Tang Mei when he saw her walking to his side.

Tang Mei also looked up at the wriggling “huge dough” at the dome. It was only one of its functions. Precisely, it’s an element pool inside Buzhou Mountain. Besides being conducive to people’s cultivation, the element in this element pool could even be made into any objects that they wanted by some powerful deities. It was a building material of Buzhou Mountain!”

Zhang Tie tried to draw some fire elements from the mountain. The moment he ran his spiritual energy, he had drawn a wisp of purest fire element out of the Elements Realm. After leaving the “huge dough” and the odd sacrificial altar at the dome, the purest fire element instantly condensed into top-quality fire element crystals, which fell off the dome heavily like raindrops.

In the blink of an eye, hundreds of top-quality fire element crystals had fallen to the ground beside Zhang Tie.

“Did all the element crystals in those emperor-level immortal palaces come from here?”

“Of course, however, very few people could enter here apart from immortal emperors in Motian Realm!”

“Did the element crystals of Emperor NvWa’s Palace also come from here?”

“No, there’re also four elements pools like this in Emperor NvWa’s Palace. You can take all the element crystals away from here. This element pool will be filled with element crystals in 360 years…”

After hearing Tang Mei’s words, Zhang Tie instantly ran his spiritual energy and caused fire element crystals to fall off the dome like raindrops. The density instantly increased by more than 10 times. Tens of thousands of fire element crystals dropped off per second.

Zhang Tie opened Castle of Black Iron and teleported all the fire element crystals into Castle of Black Iron.

Even though these element crystals were not useful now, they still had great value in the future. They could help others form their fire chakras.

Even though Castle of Black Iron could integrate with the space ball of Motian Realm, it would also take it a long time to complete it. All the resources inside Mountain Ruins were not under the control of Zhang Tie in a short period of time. Additionally, Zhang Tie was destined to return to Taixia Country. Therefore, Zhang Tie teleported these precious element crystals into Castle of Black Iron first…

Finally, the mountain of fire element inside the Elements Realm of the “huge dough” turned into millions of top-quality fire element crystals and was teleported into Castle of Black Iron.

After cleaning up all the fire element crystals in this room, Zhang Tie entered the other 3 rooms and teleported all the element crystals of the other element pools into Castle of Black Iron.

After cleaning up all the elements of the four elements pools, Zhang Tie and Tang Mei came to the front of the gate in the middle.

“Are you ready?” Tang Mei asked with a long sword in hand. Just now, she looked relaxed. But now, she turned serious.

Zhang Tie nodded as he asked, “How about you?”

Tang Mei nodded too.

Zhang Tie then took in a deep breath as he pushed open the gate in the middle…

Tang Mei flashed in first…
