Castle of Black Iron

As for wing demons; especially wing demon knights, human airships were absolutely their toys, even weaker. Any wing demon knight could easily hit down all the airships within their sight and cause great damages to humans.

There were so many airships in the sky as if they came from Wuzhou Province. Being close to each other one after another, over 500 airships were evacuating towards Huanzhou Province like a chain of barges on the canal.

This was a piece of fat. It might belong to the official or the major clans of Taixia Country.

The wing demon kept watching the airships with bloody eyes being close to the surface of the water.

The airships in the sky were alluring to wing demons. However, there were also two blurred black points ahead of the airboat in front of those airships.

The two human knights in the sky could barely find the wing demon knight under the water.

‘Damn human knights!’

The wing demon knight swore under the water. Without the two human knights, the 500-odd human airships would be completely its toys. However, because of the two human knights, the wing demon knight could only watch these toys sliding away in front of his eyes.

Of course, it could launch a strike and hit down dozens of airships; however, he would be surrounded by the two human knights. As they were all black iron knights, the wing demon knight could barely survive the siege of the two human knights.

After thinking about it for a while, the wing demon could only see those airships flying away escorted by the two human knights…

The moment Zhang Tie caught sight of that wing demon knight, Zhang Tie had already left the thunder hawk and flew towards the wing demon from tens of thousands of meters high at the speed which was 13 times the speed of sound.

With the effects of rapid moving skill and hiding skill, the sonic boom in flight was reduced to the lowest volume; additionally, Zhang Tie’s body emerged like an invisible owl.

At this moment, Zhang Tie wore a pair of metal caliga, a full-moon dragon’s soul waistband and a pair of metal wristbands. Although these items looked trivial and nobody knew what they were, they were actually Zhang Tie’s “simplified flight suit”. With the ability of divine dominator, if he flew 100,000 miles, of course, this simplified flight suit didn’t feel as comfortable and labor-saving as Chaos. However, it was enough for Zhang Tie to fly 1,000 miles by these equipments.

Zhang Tie also saw a troop of airships and the two human knights flying towards him. Zhang Tie didn’t know who was inside those airships and the airboat; however, in order to avoid from being discovered by them, Zhang Tie purposefully ascended and kept flying higher than 300,000 m. Additionally, he passed by the airships from aside instead of from above them.

When Zhang Tie flew over, the two knights also heard the faint sonic boom; however, as the sonic boom was too weak, they could barely identify the precise location of the sonic boom. What was more, the speed of sound was much slower than the speed of Zhang Tie’s movement. The two knights looked up with suspicious looks; however, they found nothing abnormal.

After discussing it for a short while, the two human knights determined to prioritize the convoy of the troop of airships. They didn’t look for the source of the faintly strange sound as this sound might be the resonance of thunder in the far or some sound on the ground…

At 13 times the speed of sound, it only took Zhang Tie 10 minutes to arrive at the lake since he fixed his eyes on the wing demon knight. However, the wing demon knight was still lurking in the lake.

Not until Zhang Tie arrived above the lake did he slow down and enter the lake quietly.

The moment Zhang Tie returned to the lake, it was like how a dragon returned to the ocean and how a tiger returned to the deep mountain.

When in flight, Zhang Tie would cause some sound more or less; however, when in water, as long as he liked, he could completely be as quiet as a bubble or a drop of water.

Ironically, not until Zhang Tie came to the side of the wing demon knight from over 1,000 miles away, the demon knight had not discovered Zhang Tie.

It was already a bit unfair for an earth knight to raid a black iron knight; however, that earth knight was a divine dominator who cultivated an emperor-level secret method and had a myriad of secret skills. Such a duel was like putting a 150 kg professional boxer and a 7-year old kid in the same ring. That’s too unfair…

Finding that the wing demon knight was still immersed in his own world and plan, Zhang Tie became a bit embarrassed.

“Ahem…”, Zhang Tie purposefully coughed in water which was finally heard by that wing demon knight through water waves.

The wing demon knight was shocked as it turned around at once; however, it saw a punch approaching him…

Zhang Tie directly punched onto the lower abdomen of the wing demon knight. Before the wing demon knight released its protective battle qi, its bones all over had been completely broken. Additionally, its eyeballs bulged 1 inch outside of its eye sockets. Its face twisted like a wrinkled dishcloth.

Besides the extremely terrifying strength, Zhang Tie’s punch also carried a strange strength. When Zhang Tie’s fist touched the wing demon’s lower abdomen, the strange strength immediately disordered the battle qi of the wing demon as a whole. At the same time, its mind sea shocked heavily as if it was going to pass out.

This punch was called Bloody Mark Three-Kill Fist that Zhang Tie had just learned from Bloody Soul Sutra . With this punch, Zhang Tie could break the opponent’s body, qi and soul. This wing demon was fortunate to be the first target of Zhang Tie soon after Zhang Tie grasped the secret skill in Bloody Soul Sutra .

Before this wing demon screamed or ran its battle qi, Zhang Tie had punched onto its head. As was imagined, this wing demon knight passed out at once.

Zhang Tie grasped its neck and teleported it into Castle of Black iron…

Since the beginning of this raid, Zhang Tie only caused some ripples on the lake when he punched towards the wing demon knight as if a big fish jumped out of the water and fell down, nothing else…

Heller’s chuckle drifted from Castle of Black Iron as he said, “Congratulations, Castle Lord, if you teleport 20-more black iron demon knights like this one, Ockham will be alive once again…”
