Castle of Black Iron

"You want to go to the world I came from? But why?" Zhang Tie shockingly watched the elder in red robe.

Rune Emperor replied with a bit of grief, "The reason is simple. As for each immortal emperor, Motian Realm was just a cage that they could barely escape. All the immortal emperors know that Motian Realm is not a complete world. The entire Motian Realm is just a piece of space-teleportation equipment that has been amplified many times. In another world, Motian Realm is just subject to the real world where you came from. Over tens of thousands of years, immortal emperors in Motian Realm have been wishing to escape out of this cage and enter the real world for freedom. Pitifully, nobody has ever succeeded..."

"Don't you care about that I've destroyed your plan and killed your subordinates for this target?"

"I've already told you. You're more valuable than the entire Dragon Emperor Immortal Palace. As long as you promise me, all the old scores will be even once and for all. I could even help you promote to a supreme-level immortal general rapidly!"

Zhang Tie revealed a brilliant smile as he watched Rune Emperor in an extreme sincere expression, saying, "Well, I agree. Do you have a crystal plate? I need one to notice you when I'm able to go back. By then, we will leave together..." After saying that, Zhang Tie rubbed his hands as his smile became more passionate and playful. "Look, I've already agreed with you. If you don't have other things, you shall allow me to leave this... immortal emperor's realm. I'm waiting for refining those fire elements. Oh, please keep secrets of my background. You could send fire immortal generals to the Forbidden City if there're surplus fire immortal generals in Dark Emperor Immortal Palace. Thank you..."

Zhang Tie's words were pretty similar to how two familiar ones greeted each other before the Catastrophe: well, let's have a journey together one day. Let's contact by phone if there's an emergency. If you don't want your furniture and account-books any more, remember to post them to me. You know my address. Bye bye!

Rune Emperor squinted his eyes at Zhang Tie straightly.

"What? Anything else?" Zhang Tie asked with a smile.

"It's simple if you want to leave. Just accept my sacred sacrifice..." Rune Emperor said calmly as he pointed at the sky by his finger. At the same time, a bizarre golden light started to circle around his fingertip like a colorful butterfly.

Golden-Soul Rune Virus!

According to Zhang Tie's knowledge about Golden-Soul Rune Virus, at the sight of the golden light, he had known that it was specially prepared for a supreme-level immortal general. 'Rune Emperor really think highly of me.'

The bit of golden light at Rune Emperor's fingertip made Zhang Tie's smile shortly stiff as he replied, "Erm... if my master knows that..."

"Your master? Who's that?" Rune Emperor asked him calmly.

"Grand Dragon Emperor..." Zhang Tie replied firmly. Of course, he was just telling a lie. Zhang Tie just wanted to know how many secrets did Rune Emperor know about him.

Zhang Tie didn't know how many secrets did Rune Emperor know about him besides monitoring him all the way till now. Therefore, Zhang Tie felt a bit worried. 'Rune Emperor knows my background; knows what I've done; knows my kinetic strike; knows my Purgatory Samsara Method; even knows my body-changing immortal bloodline. Does he know that I have Castle of Black Iron, body-separation skill and King Roc Sutra?'

Rune Emperor burst into laughter as he replied, "Your body-separation skill is unrivaled across the Motian Realm. Even the shadow demon's body-separation method of Versatile Demon Emperor couldn't match that of yours. Additionally, there's a heavenly-level immortal outfit on you. Being a piece of space-teleportation equipment, the heavenly-level immortal outfit was different than ordinary space-teleportation equipment as it could form an ecological system inside and enable you to access to it. Such a heavenly-level immortal outfit is rare even in Motian Realm. Additionally, you're cultivating a special cultivation method. It could even enable you to imitate the effects of World Shocking Sutra which you acquired from the calligraphy of the former Dragon Emperor. Such a secret method has never appeared in Motian Realm before. Your spiritual attack is also very powerful. Do you want to hear more? I was speaking highly of you just now; don't play such a trick in front of me anymore..."

After hearing his reply, Zhang Tie gradually became worried. It was his first time to expose so many trump cards since he acquired Castle of Black Iron. At this moment, Zhang Tie really felt like standing in front of others naked.

'No, it's impossible for him to know everything about me. Even though he could monitor me without being discovered, it's still impossible for him to know everything about me. He could know and see what I've done; but he could never know why I did that!' When Zhang Tie recalled what Rune Emperor said word by word, he instantly saw a beam of hope. 'Although he knows my body-separation skill, he doesn't know how to use it and its limits. Although he knows the existence of Castle of Black Iron, he only treats it as a piece of heavenly-level space-teleportation equipment that could form a complete ecological system inside. He knows that I could imitate the effects of other cultivation methods; however, he doesn't know that I'm cultivating an emperor-level classic King Roc Sutra. Additionally, he doesn't know that I'm cultivating the Great Wilderness Sutra and is not sure about the ability of my lotus-flower eyes...'

'Therefore, he's not almighty. Even the unrivaled immortal emperors are not almighty. They also don't know everything. I still have opportunities to escape from him.'

"I admit that you're right. Now that you know so much about me, do you think that I would accept your sacred sacrifice?" Zhang Tie asked Versatile Demon Emperor as his face gradually turned solemn.

"You know that you will not lose your life after accepting the sacred sacrifice. You could still keep your awareness. If you don't accept my sacred sacrifice, I'm afraid that you will break your promise..."

"I'm afraid that you will break your promise too..."

"We could make an agreement. As long as you could take me away from Motian Realm, I will detoxify your Golden-Soul Rune Virus the moment we reach the world you came from!"

Zhang Tie responded with a faint sneer, "It sounds good. But do you think that I will believe in a demon's promise?"

"What do you mean?" The Rune Emperor's eyes turned fierce at a stroke.

"After setting a trap to kill Rune Emperor, Versatile Demon Emperor has acquired the Tadpole Rune Sutra of the late Rune Emperor. Meanwhile, Versatile Demon Emperor was heavily injured by Rune Emperor and has not recovered completely. Therefore, Versatile Demon Emperor has been lurking over these years. After acquiring Tadpole Rune Sutra, Versatile Demon Emperor combined his knowledge about puppet worms which were under the control of demons and created Golden-Soul Rune Virus. Additionally, he lurked among the people in Motian Realm and founded Dark Emperor Immortal Palace. He wanted to divide and disintegrate human forces by the force of Dark Emperor Immortal Palace and create chaos among humans. He even wanted to fix your heavy losses with the power of Dark Emperor Immortal Palace. When he prepared to annex Dragon Emperor Immortal Palace, he found an immortal general who had just joined Dragon Emperor Immortal Palace was from another world. Through secret observation, he found many secrets about Zhang Tie. Additionally, this person called Zhang Tie probably knows the secret to leave Motian Realm. Therefore, he wanted to control Zhang Tie. However, he was afraid that Zhang Tie would not trust him if he exposed his identity of the demon emperor to Zhang Tie. Therefore, he decided to turn into Rune Emperor so that Zhang Tie could believe in his promise and follow his order. Do you think this story is more reasonable and could better explain the background of Golden-Soul Rune Virus than that you've fabricated?"

Watching Rune Emperor, Zhang Tie continued, "I feel this story is more reliable. What do you think about it, Your Majesty Demon Emperor? Given intelligence and tricks, nobody else could match you across Motian Realm. I believe in only a bit of what you've said just now, namely Motian Realm is really too small for superb powerhouses like you. It's just like a cage for you. Although being not a fire immortal general, I also feel it's too small..."

Watching Zhang Tie, the old man in red robe suddenly let out a sigh as he said, "It's boring to make it so explicit. If you want to battle with me, you will suffer a great loss in the end for sure. Actually, you could accept Golden-Soul Rune Virus. Smart ones always go after profit and avoid harm. Do you think that you could really escape away from me?"

"Whatever, I just don't want to cheat myself. I have to follow my consciousness!" Zhang Tie shrugged as he added, "I've told you that nothing is more difficult than death in one's life. There's only one means of communication between demons and me..."

After saying that, Zhang Tie instantly rushed forward as he shot a sword light towards the old man in red robe from his central forehead...

As Zhang Tie launched a strike, his battle qi became berserk all over. Meanwhile, he kept advancing towards the demon emperor.

——Someone would rush towards weaker ones in order to prove that he's more powerful; however, Zhang Tie always rushed towards more powerful ones in order to prove that he's more powerful...

"Go to hell..." Zhang Tie roared which was as loud as a thunder...
