Castle of Black Iron - Chapter 1712: Heading for Mountain Ruins

In the pitch-dark heavenly curtain, it was snowing heavily with wuthering wind...

Zhang Tie's original body and his substitute were flashing as fast as lightning bolts like shadows. After leaving Dragon Emperor City over 600 miles, they entered a thick cloud, where Zhang Tie ran his spiritual energy and had the mysterious energy of his invisible shen bead in his mind sea cover two of them at the same time. As a result, Zhang Tie and his substitute disappeared in a split second. Even an immortal emperor who followed them all the way here could barely find them any longer, not to mention that it was densely covered with snowy clouds in the evening.

Zhang Tie didn't know whether the red and blue devils could be invisible at the same time with invisible shen bead, but he and his substitute could be invisible at the same time after integrating with the mysterious energy of the invisible shen bead.

After hiding them, Zhang Tie made a turn and accelerated towards a rare mountain range within Dragon Emperor Bid Domain according to his memory in the speed of over 10,000 m per second.

In less than 20 minutes, a tall mountain range towering in the clouds lasting 6,000 miles had appeared in front of Zhang Tie.

The top of the mountain range was circled by a snow line. From the sky, Zhang Tie found clouds were rolling at the hillside. Above this mountain range, there were a lot of air-borne mountains, large or small.

It was unpopulated here. After being fully exploited for tens of thousands of years, nobody would come to those air-borne mountains anymore.

Like how the red and blue devils did, Zhang Tie looked around using his lotus-flower eyes at first. After finding nobody within hundreds of miles, he directly came to an air-borne mountain and entered a mountain cave.

"Here we are..." Zhang Tie took a look inside after entering the mountain cave. He found it was dry inside and nobody was there not even animals. There was even no dirt in the high altitude. The mountain cave might have remained unchanged for many years. Besides some mining traces, it was pitch-dark inside. However, with his dark visual ability, it was as bright as day here.

"Dragon Emperor" and Zhang Tie's substitute exchanged a glance with each other as they burst into laughter in unison.

Of course, Dragon Emperor was fake. If he stayed with others for a short period, his loophole would be identified for real. He could imitate others easily; however, he couldn't imitate an immortal emperor's cultivation realm and the memory of Dragon Emperor, which had evident loopholes. However, in the past minutes, Zhang Tie didn't spare any chance for anyone to check whether he was real or not. He kept launching strikes for several times like a real immortal emperor which shocked everyone else; especially the battle skill that he used the two energies in the void to expose the fire immortal general from Star Emperor Immortal Palace.

The others only saw "Dragon Emperor" mauling a powerhouse from Star Emperor Immortal Palace easily from over 50,000 m away. However, nobody knew how long had Zhang Tie prepared for that battle skill. Additionally, it cost him a great amount of spiritual energy by keeping the two energies in the void in a state of being ready for a strike. The point was that he had discovered the powerhouse from Star Emperor Immortal Palace lurking in Dragon Emperor City a few months ago. After combining with so many conditions, Zhang Tie finally shocked everyone by only one strike.

It could be said that each step tonight was within Zhang Tie's delicate plan and expectation. Except for Zhang Tie, all the people across Dragon Emperor City had been cheated. The heavenly shadow demon knight became the only sacrifice on this stage tonight.

It took Zhang Tie 8 to 9 months in playing such a performance. As a result, he successfully turned himself into the disciple of Dragon Emperor and the new Dragon Emperor of Dragon Emperor Immortal Palace.

To be honest, Zhang Tie was not completely fake because it was a reality that Zhang Tie had acquired the spiritual enlightenment of the Dragon Emperor from the latter's calligraphy. As Dragon Emperor didn't have any heir or disciple in Motian Realm, Zhang Tie was the only one who was qualified to carry forward everything of Dragon Emperor Immortal Palace across the Motian Realm.

What happened tonight just made the reality aboveboard. Meanwhile, Zhang Tie prevented a turmoil across Dragon Emperor City.

If those powerhouses lurking in Dragon Emperor City started a brawl, very few of those commoners in the city could survive in the end.

Dragon Emperor Immortal Palace and Dragon Emperor City had long been treading on eggs. However, Zhang Tie's performance tonight changed everything.

No matter what methods Zhang Tie adopted, Zhang Tie felt unregretful.

In the mountain cave, Zhang Tie's original body and substitute started to change again.

Dragon Emperor slowly turned into Zhang Tie's original look while Zhang Tie's substitute slowly turned into a strange old man that nobody else had ever seen.

"I will digest and refine the wind chakra of that heavenly shadow demon knight here. I could at least promote to one change higher..." Zhang Tie's original body said as he took a look at this mountain cave.

"Well, I will take a look at the Mountain Ruins by this opportunity..." Zhang Tie's substitute said as he took off his metal wings, leaving it inside the mountain cave.

The talk was like murmuring for Zhang Tie. He felt pretty interesting controlling two bodies to speak using his multi-tasking ability.

After that, the two bodies smiled at and clapped against each other. Then, Zhang Tie's substitute flew out of the mountain cave along the route that he came in. Zhang Tie himself then found a dry place and sat down. Eyes closed, Zhang Tie started to assimilate and refine the wind chakra.

It was really a high-efficient way for Zhang Tie to use Purgatory Samsara Method. After killing the red and blue devils, Zhang Tie won another opportunity to improve his overall strength quickly overnight.

As Zhang Tie was refining tonight's achievement in the mountain cave, his substitute was heading for the Mountain Ruins...

...

According to the map of Motian Realm, humans and demons lived in the middle space between Mountain Ruins and Yaohai Ocean.

Mountain Ruins was very large; actually, it was the largest mysterious domain in Motian Realm, which was many times larger than the total of the other domains of humans and demons. Mountain Ruins existed everywhere. As long as one could reach over 200,000 miles high in the air, he or she would be able to touch the border of Mountain Ruins.

After leaving the mountain cave, Zhang Tie's substitute directly advanced toward the sky...
