Castle of Black Iron

White clouds were floating in the sky slowly.

Time passed by.

It soon came to June, the 3593th year of Emperor NvWa's calendar with the disputes across Motian Realm.

It was already the 7th year since Zhang Tie entered the immortal prison. Over the past 7 years, many major events had happened in Motian Realm. The battle in the Mountains Plain of the Mountain Ruins where a demon emperor and dragon emperor were killed was gradually forgotten by people as time passed by. Finally, it became the topic of people like that Rune Emperor lost his life in Dark Valley and Dragon Emperor had been missing for over 900 years in Motian Realm.

Over the past 7 years, everything seemed to have been changing, except the huge black tower which was standing in the air of Mountains Plain as same as before. Even when time passed by, it didn't leave any trace on the black tower.

All the humans and demons knew that huge black tower was the legendary Infinite Immortal Prison in Motian Realm.

The immortal prison was used to confine all the devils, ghosts, specters, monsters and rebellious deities by deities in far-ancient times. Infinite Immortal Prison had been said to exist in Motian Realm for a long time; however, the immortal prison disappeared after the legendary war between deities and demons.

Previously, immortal prison was the most thrilling legend in Motian Realm. According to the legend, each generation of King Roc was responsible for managing the immortal prison. There was the most powerful deity's secret method Infinite King Roc Sutra inside the immortal prison. With the great power of Infinite King Roc Sutra, King Roc could conquer everything inside the immortal prison. Only those who had cultivated Infinite King Roc Sutra could control the entire immortal prison.

Besides Infinite King Roc Sutra, it was said that there were many outfits, secret skills, treasures and sutras left by far-ancient deities inside the immortal prison...

Of course, it was just a legend.

If one could enter the immortal prison, he would enjoy everything inside the immortal prison; if one couldn't enter it, the immortal prison was almost like a historic site.

In the beginning, many human immortal generals came to the Mountains Plain in Mountain Ruins to look at the huge black tower with reverence with different purposes. Some of them were just here as tourists; someone came here with the fluke mind of getting some benefits. Someone even wanted to open the immortal prison and occupy all the rarities and secret skills inside the immortal prison...

However, as time passed by, the third kind of people left there first. Even immortal emperors couldn't leave any trace on the huge black tower, not to mention the others. Those people had tried every method that they could. Some even released Breaking Formation Mines here. However, when they found none of these methods worked, they all left.

So did those who wanted to try their lucks in Mountains Plain. With a bit fluke mind, they might think that they were different than others; however, when those people really came to Mountains Plain and faced the integrated huge tower which didn't even have a crack, they used every method they could including worship and prayer. When they found none of these methods worked, they gradually left too.

As for the first kind of person, many travelers came here almost every day in the first couple of years. Many people were even here in groups. However, starting from the 3rd year, the population of travelers started to reduce. On the 4th year, it was said that demon generals were especially ambushing here for those human immortal generals who came here to watch the magnificent tower. From then on, fewer human immortal generals would like to go to Mountains Plain anymore. As a result, the Mountains Plain became as same as before——demons set traps here; humans then trap the demons who prepared to ambush human immortal generals here. Trap within a trap! After both parties fought here out of wits and courage for 2 years, Mountains Plain gradually became as desolate as before.

Besides the fact that the huge black tower remained unchanged forever, the hatred and battle between humans and demons continued generation after generation...

Death meant the end for many people. However, if death was regarded as a start for measuring one's value, there might only be two kinds of people in the world: those who would be forgotten after death and those who would be remembered by many people after death.

Although Zhang Tie had not come to Motian Realm for long, undoubtedly, he belonged to the second kind of person in many people's hearts.

On June 17, two immortal generals suddenly arrived at the front of the immortal prison in Mountains Plain——Su Haimei and Ying Feiqiong.

After a few years, the two people had already promoted to wind immortal generals from water immortal generals and could already enter Mountain Ruins.

After over half a month's flight and passing through the Ice and Fire Heavenly Wind Layer, the two people finally came to the front of the huge black tower meticulously.

They had already disguised themselves. At least the others couldn't recognize their original identities and beautiful looks. Given their current looks, they were just two decent male literati.

They had not leaked their real identities and beautiful looks at least before coming to the front of the huge black tower.

However, when she saw the huge black tower; especially when she came to the front of the huge black tower, Su Haimei's eyes suddenly turned red. Closely after that, she started to drop pearl-like tears. Watching Su Haimei's look, Ying Feiqiong's eyes also turned red.

Departure between alive and dead was the most sentimental thing!

"Why were you so stupid? They all said you could leave here that day. The demon emperor didn't discover you at the beginning at all. However, you exposed your own identity for the sake of a stranger's life and finally lost your own life. Why were you so stupid..." Su Haimei sobbed as she stroked the smooth surface of the tower.

Even Zhang Tie didn't know how many women were fascinated by him when he saved the immortal generals of Yin-Yang Sect in Cyanlotus City. This grand elder of Yin-Yang Sect was one of them. Previously, Su Haimei had a crush on "Donder" who used to wander lonely and secretly; when she found Donder was Zhang Tie the incumbent Dragon Emperor, Su Haimei had transferred her love to Zhang Tie unconsciously.

If Zhang Tie was still "alive", she might still not express her love to him in this way; when he found Zhang Tie was already "dead", Su Haimei didn't need to hide her love for him anymore...

At that time, only two people saw how Zhang Tie and Six-armed Demon Emperor entered the tower, namely Star Emperor and Force Emperor. However, neither of the two men were big mouths. Most of the people heard about it from others. Therefore, very few people knew the details.

In the "legends", Zhang Tie and Six-armed Demon Emperor were sucked in the immortal prison together. Undoubtedly, if the situation inside the tower was worse, neither Zhang Tie nor Six-armed Demon Emperor could survive there; if the situation inside the tower was not worse, Zhang Tie must have been killed by Six-armed Demon Emperor.

Nobody thought that Zhang Tie could survive inside; instead of Six-armed Demon Emperor.

No matter what, Zhang Tie must have died.

Additionally, this huge black tower remained silent over these years. Therefore, both Zhang Tie and Six-armed Demon Emperor must have died.

"How poor we are..." Ying Feiqiong heaved a sigh. She knew that her disciple Ji Yuelan, her senior sister Su Haimei and Su Haimei's disciple Jiang Ruoxin had long been fascinated by Zhang Tie.

When she recalled that scene when she contacted Donder temporarily in Si Clan's castle, even though Ying Feiqiong admitted that she almost had a crush on him. Thankfully, due to the short contact between them, she had not got a chance to fall in the same trap. She was relatively sober-minded.

The thing that two elders and one grand elder fell in love with the same man had almost never happened in the history of Yin-Yang Sect; not to mention that they all had an unrequited love with him.

All the females who cultivated Three-lives Sutra had to face such a catastrophe in their lives. As long as these female disciples fell in love with someone, they would feel no regret even being heavily injured. Take Xue Yuxiu as an instance, when senior brother Luo died, Xue Yuxiu almost destroyed the entire Yin-Yang Sect out of fury; she even burned herself into ashes in the end.

This time, if only Ji Yuelan and Jiang Ruoxin had promoted to heavenly immortal generals, they must also be hugging the tower and crying aloud like Su Haimei.

After staying here for more than one hour, with the persuasion of Yin Feiqiong, Su Haimei finally wiped out her tears and left Mountains Plain with Ying Feiqiong.

...

However, before getting out of Mountain Plain, Su Haimei suddenly told Ying Feiqiong, "Feiqiong, you can go back alone. I prepare to stay in Mountain Ruins for a few more months. When the core of Mountain Ruins is opened, I prepare to have a try inside..."

"Ah? Haimei, are you crazy?" Ying Feiqiong asked as she watched Su Haimei with great shock, "We've just promoted to wind immortal generals. We've not even consolidated our realm. If we deepen into the Mountain Ruins, it's nothing different than courting death. We've been risking a lot coming to Mountain Ruins..."

"Therefore, Feiqiong, you should go back. Yin-Yang Sect could not run without you. I will go there alone!" Su Haimei said resolutely as she gnashed her teeth, "It's said that there're numerous immortal outfits and secret methods in the core of Mountain Ruins. Even though in the periphery of the core of Mountain Ruins, there're also many superb items. If I could get a set of heavenly-level outfit, I might be able to break the immortal prison..."

"Ah? But the immortal prison is said to be made of the king roc's heart. Nobody or nothing could hurt it, even immortal emperors..."

"But I want to have a try!"

"But..."

"It's meaningless for me to live alone!" Su Haimei said with a desolate smile, "Even though I cannot break the immortal prison, I could at least kill some more demon generals for him with the help of immortal outfit..."

Ying Feiqiong didn't speak; however, her pupils suddenly contracted. Right then, a man in black robe flashed towards them from afar as fast as a lightning bolt.

"Long time no see, I really miss you..." Si Dan, the grandmaster of Si Clan, greeted in a vicious tone, causing the two women to change their faces greatly at once.

"Feiqiong, run..." Su Haimei roared as she forcefully pushed Ying Feiqiong...
