Castle of Black Iron

Zhang Tie had seen a lot of sage-level knights, such as Yun Zhongzi of the Great Wilderness Sect, Zuoqiu Mingyue the Military God, the old guys of the three top sects, the Abyss Monarch of demons in Taixia Country. As Zhang Tie was acquainted with these sage-level knights, he was crystal clear about the overall strength of sage-level knights and the great power of sage-level realms.

However, this old man in red robe looked so unfathomable that he was absolutely out of the reach of sage-level knights. This space was not like sage-level realm.

In Motian Realm, only immortal emperors and demon emperors were higher than sage-level knight!

Watching the old man, Zhang Tie's pupils contracted as his heart raced unconsciously.

In red robe and silver hair, the old man was heavily wrinkled as his eyes were as dark and profound as the eternal vacant space. Zhang Tie couldn't identify whether he was kind or evil. Besides, the old man's long nose was similar to the beak of a hawk which revealed his tough temperament; his thin lips felt merciless and fierce.

Zhang Tie had seen the portraits of Star Emperor and Force Emperor. Given his look, this old man was neither Star Emperor nor Force Emperor. When Zhang Tie triggered his lotus-flower eyes, he found that the old man was surrounded by a layer of transparent fog, which couldn't be seen through.

"Senior, I wonder how I should refer to you. How do you know that I was not born in Motian Realm?" Zhang Tie asked the old man calmly.

According to Zhang Tie's temperament, he would always feel frank and calm when the situation had already reached the forefront. As for whether the old man was his friend or foe and whether they needed to fight or reach a peaceful agreement, just put it straightforward. 'Now that this old man could show up at this moment and he must have been paying attention to me for more than a day given his words, I believe that it's not a coincidence for the old man to show up here.'

The more powerful one was, the more confident and straightforward he would be about his own power instead of playing any tricks on this occasion. Even though they were going to die, they preferred to die without doubts.

"Hahaha..." The old man in red robe laughed loudly. When he hid his laughter, he took a glance at Zhang Tie, saying, "I thought you would deny that you came from another world unless I used some tricks. It's not bad for you to have such an act of courage and insight!"

After hearing that the old man was going to use some tricks on him, Zhang Tie squinted his eyes as he had been ready to fight. "As a tough man, I should stand up and fight like a man. My background is diverse. It's unnecessary for me to keep it from you. However, after coming to Motian Realm, I know that there are many differences between the two worlds. If I told others that I came from another world, I'm afraid that I would be taken as a lunatic and would arouse trouble. Therefore, I didn't mean to publicize it. Now that senior has already known that, I should be honest to you. Oh, senior, you've not answered my question yet. Is there anything wrong with your name?"

"You've just killed two of my subordinates and destroyed my plan in Cyan Lotus City, Woods Medium-sized Domain, don't you know who I am?" the old man asked casually as he watched Zhang Tie with a smile, "As for why I know you were not born in Motian Realm, it's simple. I've discovered it the moment I saw you. When humans and demons were born in Motian Realm, they had already lit all the surging points on their spines; additionally, there was a wisp of congenital qi in those surging points. However, all the surging points on your spine were lit up after you were born. You might think that others couldn't discover it; whereas, in my eyes, they are as eye-catching as a jumby bean in a pile of mung beans!"

"You're the head of Dark Emperor Immortal Palace?" Zhang Tie asked as he contracted his muscles and released his protective battle qi and spiritual energy at his full efforts. Meanwhile, he was trying his best to work out solutions to respond to the old man's attack.

If Zhang Tie was out of the realm, he might have turned around and fled; because Zhang Tie was clear that he didn't even have 1% of chance to defeat the immortal emperor, not to mention that he was in the realm of this immortal emperor-level enemy. He could never escape away unless he defeated this old man.

"You can call me Your Majesty or Rune Emperor just like how the others called me before!" The old man in red robe revealed one more secret.

"Rune Emperor?" Zhang Tie gazed at the old man out of great shock, "Wasn't Rune Emperor screwed by Versatile Demon Emperor and killed by a large battle formation of over 10,000 demon immortal generals in the Dark Valley many years ago?"

"I was almost killed at that time!" the old man in red robe replied with a faint smile, "However, at such a high realm, it's not easy for me to die even if I wanted to. What's more, Versatile Demon Emperor didn't know the significance of my Tadpole Rune Sutra..."

"Now that you're a human immortal general, why did you establish Dark Emperor Immortal Palace to disrupt the overall situation facing humans?"

"What do you think?"

With a faint frown, Zhang Tie looked straight into the eyes of the old man in red robe as a whim occurred to him. In a split second, Zhang Tie realized why Rune Emperor had founded Dark Emperor Immortal Palace. "There's only one reason. After being ambushed by Demon Emperor, although you were not dead, you suffered a great loss. When you almost recovered, you found that your influence couldn't match that of before anymore. Additionally, you found that Rune Emperor Immortal Palace had already perished. As a top power, of course, you want to recover your influence as soon as possible. All this eventually led you to establish another immortal palace. However, as the territory of Motian Realm was shared between major human forces, it was not easy for you to establish another emperor-level immortal palace anymore aboveboard; therefore, you could only carry it out secretly..."

"Right, you're smart. I appreciate you more!" the old man in red robe clapped his hands as he said, "But you've only hit half. If you have any question, just let me know!"

Another whim occurred to Zhang Tie as he asked, "When did you discover me?"

"Now that you're so smart, you could guess it again?"

Being silent, Zhang Tie started to consider it with a tight frown. This question was very important. If he didn't figure it out, he would not sleep well; nor would he have a good appetite. Zhang Tie was completely confused about his mistakes and loopholes. 'Although we are talking peacefully and calmly at this moment, I might be killed by this Rune Emperor after a short while.'

When Zhang Tie was happy for getting the biggest achievement today, he fell into the realm of the immortal emperor. After putting one piece in the wrong place, he had already lost the game. Therefore, Zhang Tie wanted to find out his loopholes as he started to recall each detail and scene since he came to Motian Realm seriously.

After a long while, Zhang Tie suddenly raised his head as he heaved a sigh, saying, "It turns out that you've already been in Dragon Emperor City when I arrived at Dragon Emperor City for the first time. You've already made your plan in Dragon Emperor Immortal Palace for many years and have long treated Dragon Emperor Immortal Palace as the flesh in your tray. When Dragon Emperor Immortal Place recruited immortal generals on a large scale and shrunk its force back to Dragon Emperor City, you might have already wanted to gulp it down. As for power, before you wanted to take an action, of course, you needed to confirm whether there were someone tricky or moles of other emperor-level immortal palaces among the new immortal generals in case of trouble. Therefore, you should have already noticed me the moment our airboat arrived at Dragon Emperor City or Flyingdragon Mountain Villa!"

After saying that, Zhang Tie revealed a bitter smile as he couldn't imagine that he had won the attention of an immortal emperor-level power the moment he arrived at Dragon Emperor City. After retrospecting it carefully, Zhang Tie realized that he was indeed a bit careless. Before he came to Dragon Emperor City, he had already known the bad situation facing Dragon Emperor Immortal Palace and that Dragon Emperor Immortal Palace might have already become the target of immortal-emperor powers. There were absolutely many surging hidden forces in Dragon Emperor City. However, Zhang Tie still chose to involve himself in. He realized that he was indeed a bit presumptuous inside.

What was more, Zhang Tie felt that he was innocent. 'F*ck, there's no immortal-emperor level powerhouses at all in Taixia Country.' How could a shadow knight know the terrifying power of an immortal emperor-level powerhouse? How would he know that the fact that he was not an aborigine of Motian Realm was instantly exposed the moment someone took a look at him from somewhere secretly. This was Zhang Tie's top secret in this world. Therefore, Zhang Tie realized that there was a sharp difference between him and this immortal-emperor level powerhouse...

"Hmm, not bad. Exactly, I had intended to kill the other elders of Dragon Emperor Palace so as to pave a way for Xia Yangming and Shi Zhongyu at that time. But I didn't imagine that I could discover you in Dragon Emperor City!" Rune Emperor said as his dark and profound eyes suddenly shone. Gazing at Zhang Tie, he looked a bit greedy and surprised, saying, "As for me, you're my biggest achievement in Dragon Emperor City. You're the real surprise. In my opinion, your value is far greater than that of the entire Dragon Emperor Immortal Palace. You're priceless. God really treats me good. After surviving the battle, I discovered you, hahaha..."

Rune Emperor started to laugh loudly. Facing his crazy laugh and greedy and surprised look, Zhang Tie felt cold inside as his heart raced while his anus contracted despite being always composed. 'Damn it! Hopefully, this old douchebag doesn't have any abnormal hobby. I just look a bit handsome; instead of being very handsome. Even if this old douchebag has some strange hobby, he shouldn't find me...'

"I've already been trapped by you. Do you want to take revenge for Qian Changqing, Xia Yangming and Shi Zhongyu?" Zhang Tie asked as he pretended to be composed.

"Take revenge for them?" Rune Emperor stopped laughing as he shook his head, saying, "You're wrong. I would not avenge anybody's death in the Motian Realm. They're just some fire immortal generals. Their meaning of existence was to sacrifice themselves for me. If you want, I could find some more for you. You could refine their chakras and promote to a fire immortal general as soon as possible, even a supreme-level immortal general!"

"What do you want then?"

"I want you to be my guide!"

"Be your guide?" Zhang Tie blinked his eyes as he thought he had misheard it, "You want me to be your guide?"

"Right, I want you to be my guide." Rune Emperor nodded seriously.

Zhang Tie revealed a faint smile as he replied, "Is there any place that you don't know in Motian Realm?"

"Take me to your world. Now that you could come here, you could leave too..." Rune Emperor watched Zhang Tie as two fierce flames blazed in his dark and profound eyes...
