Castle of Black Iron

Watching so many demon generals gathering, even idiots could guess that something was wrong, not to mention Zhang Tie.

During these days when he stayed with Immortal Being in Cloud, Zhang Tie gained a lot of information and knowledge about demons in Mountain Ruins. Being different than that under Mountain Ruins, only a few places in Mountain Ruins could be controlled by humans or demons. If Mountain Ruins was taken as an ocean, humans and demons just occupied some isles in the ocean. These isles were secret realms in the Mountain Ruins which became the strongholds of humans or demons in Mountain Ruins.

Immortal Being in Cloud told Zhang Tie that it was almost impossible for them to meet many demon generals at the same time unless they were close to those secret realms which were occupied by demons.

Tranquil Valley where they set a trap and this air zone where Zhang Tie was searching over were both "barren zones" far away from the strongholds of demons and humans. To a certain degree, such places were "relatively safe" where he could barely meet the "main force" of demons...

The experience of Immortal Being in Cloud was very useful. However, at this moment, his experience was subverted——A few days ago, Immortal Being in Cloud patted his chest and promised Zhang Tie that they wouldn't meet many demon generals at the same time; however, more and more demon generals started to appear in front of Zhang Tie's eyes at this moment. All of them were flying towards one direction.

'Something big must have happened!'

Zhang Tie mumbled.

Generally, when a human immortal general met such an occasion, he must turn around and escape away right now. However, Zhang Tie was an exception. Although his heart was pounding, his desire for adventure surged instantly due to great curiosity. At the same time, a bizarre current reached all of his cells from his spine. Closely after that, his adrenaline soared. Besides being extremely thrilled, he started to secrete sweet saliva rapidly. Meanwhile, all of his spiritual energy in his mind sea and battle qi in his qi sea became active at a stroke...

On this occasion, if Zhang Tie turned around and escaped away, he even felt not living up to the knowledge and secret methods that he had grasped.

'Don't be motherf*cking afraid. In the worst scenario, I will expose my real identity. If I determine to escape, very few demons could catch up with me. Even if I were chased by demon emperors, I could hide myself in Castle of Black Iron at the critical moment. When I come out of Castle of Black Iron, I will change my look. I'm barefoot while demons are in shoes. No matter what, demons will suffer a greater loss than me...'

After thinking it through, Zhang Tie's bravery surged as he didn't have any concern anymore. He just gazed at those demon generals and followed them towards one direction...

Being invisible, Zhang Tie didn't even reveal a bit of qi. At the same time, he flew towards one direction with those demon generals with a distance of at least 60 miles.

After a few hours, the night gradually fell. However, Zhang Tie found more and more demon generals gathering in the sky. There were more than 20 demon generals in his eyes, most of which were spider demons.

After the night fell, these demon generals didn't completely release their protective battle qi in flight; nor did they give out any light or battle qi. All of them were traveling in the dark like specters. On this occasion, average human immortal generals could barely discover these demon generals from a bit farther away; within a short distance, both parties had the same possibility to find each other. Actually, these demon generals were also looking for their enemies on the way...

...

At this moment, many air-floating mountains appeared in front, large or small. At first glance, there were tens of thousands of air-floating mountains in this air zone. They were just slowly moving in the air; some were like duckweeds in the ocean; some were like lofty heavens-reaching pillars; some were like creeping huge tortoises; some were like undulating, virile dragons, to name a few. Floating in the sky, they were like an artificial maze.

Those demon generals flew into this air zone one after another.

People could barely see so many air-floating mountains in an air zone even in Mountain Ruins. When Zhang Tie followed these demon generals into this air zone, he recalled what Immortal Being in Cloud told him about Mountain Ruins. He faintly felt that this region was Mountains Plain as was described by Immortal Being in Cloud.

'But Immortal Being in Cloud didn't mention that anything in Mountains Plain was worth so many demon generals to gather here. Did... did demons discover something or have any conspiracy here?'

Zhang Tie's heart pounded once as he kept a close eye on the heavenly spider demon knight ahead of those demon generals.

After traveling across those air-floating mountains for more than 2 hours, Zhang Tie had followed that heavenly spider demon knight to the center of those mountains. In this central area, there were 7 eye-catching air-floating mountain peaks, each of which was higher than 100,000 m. At the sight of them, Zhang Tie had confirmed that he was in Mountain Plain; because it was as same as was described by Immortal Being in Cloud.

According to Immortal Being in Cloud, the latest battle between human and demon powers in Mountains Plain was over 200 years ago. In ordinary days, as so many mountains were in Mountains Plain, it was easy to hide here; therefore, human immortal generals or demon generals could be easily ambushed in this region. Therefore, few human or demon powers would enter this region without any reason.

After entering the central area of Mountains Plain, the heavenly spider demon knight instantly came to the back of a mountain and disappeared. All the other demon powers also followed him in.

It was estimated that that valley was the gathering place of demon powers. Zhang Tie then meticulously flew to the place 10,000 m away from that mountain peak. After hiding himself in a smaller air-floating mountain, Zhang Tie released his spiritual energy, which then "swam" straight to the back of the mountain peak as if Zhang Tie was there himself...

His spiritual energy could move much faster than him. In the blink of an eye, Zhang Tie had traveled to the front of that mountain peak spiritually. Zhang Tie held his breath the moment his spiritual energy penetrated through that mountain peak.

There was a vast, open, deep valley behind that over 100,000 m higher mountain peak. At this moment, the valley had been completely destroyed. The deep valley was divided into two halves from the center by a huge, deep, round pit whose diameter was tens of thousands of meters. It was caused after the ground was hit by a meteorolite. The surrounding region of that huge, deep pit was completely destroyed by the strong impact wave. However, a huge black, lofty tower higher than 10,000 m was standing in the huge pit. The entire black tower was covered with looming black runes. The entire huge tower was releasing a frightening, time-honored, powerful qi.

If not that huge pit, this huge black tower could barely be discovered as it was 10,000 m beneath the ground of this valley.

At this moment, the huge black tower had long been closely surrounded by large batches of demon powers. At the glance of them, Zhang Tie had known there were over 1,000 demon powers around the huge black tower. What shocked Zhang Tie was that over 70% of them were spider demon powers.

Most of the 700-800 spider demons were in grim battle armors. Additionally, 40-50 spider demons were in black cloaks; over 10 spider demons were in red cloaks.

'F*ck, have all the spider demon powers in Motian Realm gathered here? What the hell!'

Watching so many demon powers gathering here, Zhang Tie had gooseflesh all over. Not until then did Zhang Tie know why Immortal Being in Cloud's trap became ineffective. If all the spider demons across Mountain Ruins were gathering here, how could the trap of Immortal Being in Cloud catch the attention of spider demons?

All the demon knights were gazing at the top of that huge black tower with excitement.

Zhang Tie's spirit extended along the direction where those demon knights were looking at as he instantly noticed two people being in an impasse.

One of the two people was an old man in blue robe. He was standing on the top of the huge black tower as a 33 cm-higher small black pagoda was suspending above his head and giving out a brilliant light. The brilliant light formed a semi-transparent round cover which covered the old man and the huge black tower under his foot like his protective battle qi.

The other one was a tall and strong spider demon in black crown and golden cloak, who put his 6 palms on the semi-transparent cover as he was releasing a powerful battle qi wave. At the same time, the semi-transparent cover was undulating like ripples which might break at any time...

Whenever the semi-transparent cover moved, the old man in blue robe would tremble all over and spurt out blood. As a result, his blue robe had been purplish-red...

"If you surrender to me now, you could survive..." The demon emperor in golden cloak opened his mouth coldly...
