Castle of Black Iron

It only took Zhang Tie less than 2 minutes to catch up with the fleet of Dragon Emperor Immortal Palace from over 600 miles away at a terrifyingly high speed.

After Zhang Tie's spiritual energy turned real, with his flight ability as a divine dominator, Zhang Tie's speed increased by almost 8% in the air. He moved more leisurely in the air like a dual-drive engine being injected with high-efficient fiery oil. Although the engine remained unchanged, its output power became smoother and greater.

Not until he fully extended his metal wings did Zhang Tie start to push forward slowly by battle qi. After releasing his breath, Zhang Tie rapidly retrospected his plan in mind and ensured there was no loophole.

'The red and blue devils were going to catch a captive so as to ask whether there was a powerhouse above heavenly knight in the fleet. It's a good chance for me. Although I'm not afraid of them, I don't want to expose my body separation skill. Therefore, I could only solve them one after another for the safety of the innocent people in the fleet. The separation of the two heavenly knights will spare a chance for me to kill them respectively.'

The nickname red and blue devils were vivid. Although Zhang Tie didn't know their real names, he didn't care as he had already treated them as blue and red devils in his heart.

'The blue devil appears to be not as smart as the red one despite the secret item invisible (shen) bead. The invisible bead carries a pretty abnormal effect; however, I could take advantage of it. Because the blue devil doesn't know that I've already seen through his intention. As the blue devil becomes absent-minded, I could deal with it as fast as I can. After that, I will raid the red one. I swear to turn the two scumbags into ashes.'

Zhang Tie was not scared of the two weird scumbags; instead, he was thrilled inside.

Zhang Tie felt like watching brilliant fruits of brilliance and bloody fruits of bloodlines and two complete water chakras which were waiting for him to be absorbed. Due to the fierce reaction of Purgatory Samsara Method, Zhang Tie was always very considerate about using it. Unless demons or big notorious criminals, he didn't use such a secret method on his energies. As for Zhang Tie, the use of Purgatory Samsara Method was ethical. Zhang Tie didn't mind shattering and absorbing the chakras of those real notorious b*stards. Take the water immortal general of Star Emperor Immortal Palace that he killed in Heavenly Square City a few days ago as an instance, although he was also Zhang Tie's enemy due to different stances, Zhang Tie didn't absorb his water chakra; instead, he just chopped off his head in the end.

Zhang Tie paid tribute to his enemies and opponents, which could be killed; yet couldn't be insulted or mistreated.

Apparently, red and blue devils were opponents that didn't need Zhang Tie's respect. After hearing their talk in the mountain cave and seeing those terrifying, miserable female corpses in there, Zhang Tie had already treated the two people as demons. He could kill them in every means he could without a sense of guilt or mental burden.

Zhang Tie circled around the fleet as he gradually left it. As a result, he was over 60 miles away from the last airboat.

Such an alert distance was not far; especially for a fleet in the air.

The airboats flew in a relatively open air zone while Zhang Tie penetrated through those air-borne mountains far away from the fleet. At the same time, he seriously kept "scanning" those airborne mountains for hidden dangerous things or figures. Anyone who saw Zhang Tie would feel him fulfilling his task sincerely.

Of course, in the eyes of the blue devil, such a little immortal general was simply a gift from God. As Zhang Tie was far away from the fleet and there were so many airborne mountains in the surroundings, even if they made some noise, it would not arouse the attention of the powerhouses on the airboats, even if there were.

When the blue devil flew off the mountain cave invisibly, it was not attached with those tracing feathers that Zhang Tie had set at the entrance. This really shocked Zhang Tie. However, watching the blue devil flying towards the fleet, Zhang Tie finally became reassured.

It was definitely not because the blue devil made Zhang Tie's tracing feathers ineffective; instead, it must be the invisible shen bead that blue devil carried.

When the blue devil was over 120 miles away from the fleet, it caught sight of Zhang Tie who was penetrating through those airborne mountains. The blue devil instantly changed its direction and accelerated towards Zhang Tie with strong killing intent. When it was less than 10,000 m away from Zhang Tie, it slowed down its speed at a stroke in case of arousing Zhang Tie's attention. After that, it continued to approach Zhang Tie at a speed slightly greater than that of Zhang Tie.

Only after a few seconds, the blue devil had been less than 1,000 m away from Zhang Tie.

The blue devil then became more meticulous like a fierce beast which was going to catch its prey. Besides slowing down, it even circled around Zhang Tie for a few seconds. After confirming that there weren't any ambush in the surroundings, it didn't charge at Zhang Tie directly; instead, it made a detour around Zhang Tie and stopped at thousands of meters ahead of Zhang Tie, where it was ready for the prey.

The blue devil stayed in a valley of an airborne mountain which lasted dozens of miles. Zhang Tie was flying with the fleet in the same direction along this valley; meanwhile, he was "seriously" checking the situation in the valley in case of emergency.

The terrain and space of the valley were relatively narrow. As a result, the response in an emergency would be limited. Additionally, the valley could block the inspection from the fleet. As long as the noise was not loud here, the powerhouses in the fleet in the distance would not discover it, including the wind immortal general.

The blue devil was good predator; however, it didn't know that it had selected the same location for action as Zhang Tie with the same reason.

The blue devil was lurking there quietly like a poisonous spider who extended its web while accumulating its venom, waiting for the innocent "bug" and pricking its fangs into the prey. After completely paralyzing and disabling the prey, it would enjoy the good food.

However, the confident blue devil didn't know that it had long caught the attention of Zhang Tie. Since the beginning, Zhang Tie had been paying attention to its movement, even if it remained innocent apparently.

The blue devil was making a trap to capture Zhang Tie, which was the same trap that Zhang Tie was using to kill it.

In the blink of an eye, Zhang Tie had been less than 1,000 m away from the blue devil.

Zhang Tie saw the blue devil raising its hand and moving its body in the air. It was calculating Zhang Tie's route and waiting to incapacitate Zhang Tie when he arrived in front of it. As for a low-level knight, it would prove fatal if a heavenly knight touched his body by hand without releasing his protective battle qi. It was like sending a little white rabbit under the teeth of a timber wolf. The heavenly knight could use many methods to break the low-end immortal general into pieces or subdue him in a split second.

It was definitely more difficult to subdue a knight than killing him without making a loud noise. The predator should launch a lightning strike when the prey was absent-minded.

The blue devil made a perfect plan; pitifully, it chose the wrong target.

Zhang Tie just flew leisurely, gradually narrowing the distance between him and the blue devil, 1,000 m, 800 m, 600 m, 400 m, 200 m and 100 m...in less than 7 seconds, Zhang Tie was already 50 m away from the blue devil.

Even if he had not seen the face of the blue devil, Zhang Tie could still sense the evil fleer of the blue devil. Even so, Zhang Tie still remained relaxed.

At 50 m, the blue devil raised its hand again; at 20 m, the blue devil extended its arms and was ready to charge out like a venomous snake catching its prey and a lion catching a rabbit.

Within 0.001 s, the blue devil had reached 5 m away from Zhang Tie. When the blue devil thought the battle was coming to an end...

Deity-killing Sword, out!

Just when the blue devil's hand was about to touch Zhang Tie, Zhang Tie's central frown suddenly turned bright as he shot his deity-killing sword into the mind sea of the blue devil without any omen.

After Zhang Tie's spiritual energy turned real, his deity-killing sword also turned real. After flying off Zhang Tie's central frown, it turned into a 3-cm long golden sword and hit the target...

Like a fish being towed out of the water, the blue devil instantly became visible. Meanwhile, its ears, eyes, mouth and nose spurted out blood in a pretty miserable way as it watched Zhang Tie with a frightened look as if Zhang Tie was a ghost...
