Castle of Black Iron

Yan Feiqing's virtual image was very strange. It was Zhang Tie's first time to see such a virtual image which was completely like a 10-m long silver shuttle. Being wrapped by that silver shuttle, they flew in the sky rapidly...

'Maybe this is not a virtual image at all but a secret method. It might just be similar to the virtual image in effect and is used to save her life. There're so many secret methods in Taixia Country, I couldn't know all of them whatsoever!'

The heavenly demon knights kept catching up with them with a distance of less than 5,000 m.

This might be a long distance for commoners; however, it would only take a heavenly demon knight a few seconds to finish it. Yan Feiqing couldn't extend the distance between them and that heavenly demon knight; instead, that heavenly demon knight was gradually narrowing the distance between him and Yan Feiqing. Only after a few minutes, their distance had been narrowed to about 4,500 m...

When Han Zhengfang was severely wounded and escaped out of Xuanyuan Hill using the secret method of Bloody Soul Sutra, he also reached almost 4 times the speed of sound. Given the speeds of Yan Feiqing and that heavenly demon knight, Zhang Tie immediately understood it. As for ordinary heavenly knights, they might only reach 4-5 times the speed of sound normally; if they wanted to move faster, it depended on their cultivation bases and overall strength.

The heavenly demon knight kept approaching them aggressively with its eyes closely on Zhang Tie and Yan Feiqing.

"You can never escape away..." From over 4,000 m away, the heavenly demon knight's voice sounded in their ears, "The armored shadow knight. When I catch you, I will withdraw each of your bones out of your body and make your skull into a cup..."

When knights used their secret sound-transmitting skill, they spurted their pure battle qis out of their mouth by turning them into fine waves through their chests, abdomens and throats. Therefore, their sounds could be transmitted far away at a speed many times greater than the speed of sound while not being destructive. However, only heavenly knights could transmit their voice secretly from over 4,000 m away.

As Zhang Tie's first strike was unusual and was in his Chaos, that heavenly demon knight treated him as a shadow knight.

It was not simply threatening. Now that a heavenly knight's voice could enter their ears, it indicated that his battle qi strike would soon arrive.

"Is the shuttle your virtual image?" Zhang Tie asked Yan Feiqing secretly.

"It's one of my secret methods. It's neither a virtual image nor a non-virtual image..." Yan Feiqing replied as her face turned abnormally pale and as icy and crystal as jade. Even in flight, Yan Feiqing was also releasing a faintly cold qi, which formed a thin fog around her body.

Zhang Tie didn't know about Yan Feiqing's current situation. He didn't know whether the cold qi was aroused by her secret method or caused by the poisonous Demon God's golden viper. It was hard to judge it; however, her cold qi and pale face didn't look good. Therefore, Zhang Tie cut the crap, "I'm afraid that the demon knight would strike us when he was about 3,000 m away from us. I could slow down his speed by darting spears. However, I need your coordination..."

"How?"

"When I would dart my spears, could you stop releasing this virtual image for the time being; it would work even for a millisecond. If you cannot do that, just let me go. I will block him. You leave first..." Zhang Tie put it straightforwardly. However, he didn't know that what he said sounded like that he was going to sacrifice himself for the sake of Yan Feiqing at this moment.

After hearing Zhang Tie's words, Yan Feiqing turned around as she gazed at Zhang Tie's face under his mask. After being silent for a few seconds, she opened her mouth, "I could control the virtual image of this Fantasy Fair Heavens-Breaking Boat, just send me a signal..."

After hearing Yan Feiqing's words, Zhang Tie knew what this virtual image was called. It was a special name. Not until now did Zhang Tie know that there was such a bizarre secret method whose effect could be similar to that of the virtual image. This secret method was simply a wholly new tool. That was amazing! When Zhang Tie recalled his incomplete King Roc Sutra, he could only let out a sigh inside.

"Fine. When I pinch your hand, you remove the shield of this Fantasy Fair Heavens-Breaking Boat for the time being..."

"You eject when I pinch you..." Yan Feiqing said icily. Even in this state, she also maintained a mighty position as she didn't want Zhang Tie to touch her hand casually.

'You eject when I pinch you?'

Zhang Tie muttered inside as he felt her words sounded a bit weird. However, in this case, Zhang Tie dared not make a joke with her. Zhang Tie knew that this kind of woman had the weirdest temperament. Sometimes, a common sentence might irritate her. As a result, she might chase after you with a saber. Therefore, Zhang Tie directly replied, "Fine!"

Soon after that, an ordinary spear appeared in Zhang Tie's hand. Closely after that, Zhang Tie felt Yan Feiqing to intensify her gripping power. Zhang Tie then instantly darted his spear towards that heavenly demon knight.

When the spear left Zhang Tie's hand, the virtual image that covered the two people disappeared in a millisecond. Closely after Zhang Tie finished his ejection, the Fantasy Fairy Heavens-Breaking Boat recovered its original look.

It was such a transient period that even though they were not covered by the Fantasy Fairy Heavens-Breaking Boat, their flight speed would also not be influenced due to great inertia.

When the spear left Zhang Tie's hand, it had reached several times the speed of sound. Zhang Tie didn't trigger his ability as a divine dominator because he felt it was not necessary for him to manifest that trump card at that moment.

The spear that Zhang Tie had thrown collided with the heavenly demon knight. Due to the great speed of the heavenly demon knight, the relative speed between the spear and the heavenly demon knight increased by 4 times abruptly and the spear became much more powerful...

This principle was akin to how a bird could destroy an airplane in the sky.

Zhang Tie threw a spear instead of a bird; neither the heavenly demon knight was an airplane. The heavenly demon knight only had 3 choices to deal with the spear which was darting towards it at a speed of almost 10 times the speed of sound, namely, face-to-face, dodge and hit it down.

Whichever choice it made, it would slow down.

The first spear was hit down by the heavenly demon knight from 2,000 m away. During this interval, the distance between the Fantasy Fairy Heavens-Breaking Boat which covered the Zhang Tie and Yan Feiqing and the heavenly demon knight increased by over 50 m at once.

Zhang Tie burst out into laughter as one more spear appeared in his hand, "One more..."

Yan Feiqing pinched Zhang Tie's hand once again. Zhang Tie then threw the second spear, causing a loud sonic boom in the night air...

The spear was hit down once again. However, the distance expanded by 100 more meters.

The heavenly demon knight was driven mad as it kept screaming loudly...

'This method works!'

Zhang Tie was spirited, 'Who said that the bolt-in-palm, the highest realm of spear throwing skill could only be used to deal with battle spirits at most? In this case, such a simple spear throwing skill could absolutely save our lives. Even a heavenly demon knight is at the end of its rope.'

...

After 1 hour later, the distance had been expanded to over 10,000 m. Whenever the heavenly demon knight approached a range, Zhang Tie would throw his spear towards it so as to expand the distance once again. When Zhang Tie felt that they could completely extricate it, Yan Feiqing's snow face suddenly turned red while she spurted out a mouth of blood...

At this moment, the two people might have been out of the territory of Wuzhou Province and entered the wilderness while an endless lake appeared in front of them. The Fantasy Fairy Heavens-Breaking Boat suddenly quivered a bit as it instantly dove into the wild lake out of control or on purpose, arousing a 100 m higher billow...
