Castle of Black Iron

The moment they entered the water, the Fantasy Fairy Heavens-Breaking Boat of Yan Feiqing had collapsed being influenced by the great impact force and water pressure. The cold qi over this woman even made Zhang Tie tremble once and froze her body in a split second…

Zhang Tie ran his battle qi and shattered the ice over Yan Feiqing. After that, he found her lips were so pale that they looked almost transparent.

‘Damn, that’s not good.’

“Ahh, are you okay?” Zhang Tie asked as he started to accelerate in water by pulling Yan Feiqing’s arm.

In water, Zhang Tie could be as free as fish. Even though Zhang Tie didn’t use his ability as a divine dominator, he could also reach over 1,000 m per second, which could even match their speed in air.

In the case of Zhang Tie, it was not difficult for him to extricate from the chase of the heavenly demon knight. However, he had to consider well about the method.

Since he appeared, Yan Feiqing had been treating him calmly. Additionally, as he had shown his Thor’s Hammer in front of her and met her before, Zhang Tie didn’t know whether this woman knew his real identity or not. Zhang Tie didn’t want to expose his ability as a divine dominator to this woman; neither did he allow this woman to be bullied by demons; therefore, it was a bit tricky now.

“There’s a huge hole at the bottom of the lake in front of us…enter it…” Yan Feiqing said faintly.

After hearing Yan Feiqing’s words, Zhang Tie became relaxed at once——it turns out that Yan Feiqing has been here before. Nice!

Zhang Tie hurriedly rushed towards that hole with Yan Feiqing. Being in their protective battle qis, they were moving as fast as torpedoes.

After hearing the noise from behind, Zhang Tie knew that the heavenly demon knight had been approaching them.

They were in a saltwater lake in the wilderness. The salinity of water must have been in full saturation. With no fish in the lake, there were only a few aquatic plants and a large area of salt crystals at the bottom of the lake.

In salt water, sound’s transmission speed could almost reach 1,500 m per second. Therefore, they could easily hear the noise from behind them. Given the decibel, the heavenly iron-armored demon knight was even moving faster than Zhang Tie in water as their distance was constantly narrowing. Zhang Tie was really startled by that. Not until then did Zhang Tie realize that iron-armored demon could move so fast in water because the shell and scales over iron-armored demons could reduce resistance to its minimum in water. On the premise that Zhang Tie didn’t trigger his ability as divine dominator or Castle of Black Iron, the heavenly iron-armored demon knight could even move a bit faster than him in water.

Wing demons were responsible for the air; spider demons were responsible for the earth while iron-armored demons were amphibious which could even move faster in water than on earth. This was the establishment of the main arms of the services of demons.

‘F*ck!’

Zhang Tie hurriedly rushed towards that huge hole while pulling Yan Feiqing’s arm.

In water, Zhang Tie’s spear didn’t work anymore. Zhang Tie had tried before. Although water looked weak, it could form numerous barriers to weapons being darted in it. No matter how powerful your spear was, as long as it reached 500 m away in water, it would lose its power.

After moving forward less than 120 miles in water, they had seen a pitch-dark hole in front of them. The distance between them and the heavenly demon knight also shrunk to about 2,000 m from over 10,000 m…

“You can never escape…” A grim and sinister sound drifted from behind together with the heavenly demon knight’s powerful battle qi strike from over 2,000 m away.

The moment the heavenly demon knight launched a strike, the powerful battle qi strike had directed the water all the way towards Zhang Tie and Yan Feiqing in terms of a light pillar-like impact wave.

When in water, Zhang Tie had an extremely sensitive sense. The moment his surrounding water flows moved, Zhang Tie had sensed great strength from behind. Zhang Tie instantly punched back while surging forward…

As the danger approached, even Yan Feiqing who was a bit weak lashed out a sword towards the heavenly demon knight…

In the great shock, Zhang Tie instantly felt his chest and back being hammered heavily by two forging hammers of hydraulic presses. After being involved by the aftermaths of the heavenly demon knight’s strike, his Chaos crashed. As a result, Zhang Tie felt sweet in his throat while he almost spurted out a mouth of blood.

Zhang Tie swallowed it back. However, Yan Feiqing who had long been injured spurted out a mouth of blood.

‘Is that the power of a heavenly demon knight?’

This strike was the first round of the fight between Zhang Tie and a heavenly-level demon knight.

Although Han Zhengfang was a heavenly knight, he had declined to be a shadow knight when he was killed by Zhang Tie.

Both the halos priest of Sacred Light Empire and Gao Tianzhao were shadow knights.

Honestly, without using the ability of a divine dominator, Zhang Tie felt that the heavenly knight could kill him in an overwhelming way. The heavenly demon knight’s strike could be so destructive over 2,000 deep in water, not to mention in the sky or in close combat.

After this strike, Zhang Tie sped up with the strength of counter-shock in water as he instantly entered that hole together with Yan Feiqing.

The diameter of the entrance of the hole was over 100 m. After entering the hole, he found that the hole extended all the way to the underground space. After hundreds of meters, the cave constantly shrunk with some bypasses…

“The 3rd on the left…” Yan Feiqing’s voice entered Zhang Tie’s ears once again. Zhang Tie immediately rushed inside.

It was a complex underground watercourse like the crisscrossed roots of an old tree. After entering the 3rd hole on the left for less than 500 m, Zhang Tie met another bypass.

“2nd on the right…” Yan Feiqing opened her mouth while her voice sounded weaker. Zhang Tie instantly rushed into the 2nd watercourse on the right side.

At this moment, the diameter of the watercourse had been only a few meters high. As Zhang Tie moved forward, he kept dropping alchemist’ bombs into the pits in that watercourse like setting torpedoes.

After moving hundreds of meters ahead, he ran his spiritual energy and detonated those alchemist’s bombs directly.

With the loud booms and the impact waves in water, Zhang Tie directly destroyed a 100 m long watercourse. When the impact wave reached them from behind, their protective battle qi could withstand it easily.

Zhang Tie was thinking about that, construction would always be more difficult than destruction. Take a kid building a sand castle on the beach as an instance, it might take a kid a couple of hours to build a sand castle; however, it would take another kid only half a minute to destroy that castle. It was easy for Zhang Tie to destroy a section of the watercourse; however, it would take that heavenly demon knight much longer than him to break through that watercourse. No matter what, it couldn’t crash onto the rocks with its head.

As was imagined, the moment Zhang Tie ruined that section of the watercourse, he had heard the roars and earthshaking strikes from that heavenly demon knight.

Yan Feiqing opened her mouth which was slightly quivering, “Turn right…”

There were two watercourses in front of them. Zhang Tie directly entered the right one. After that, he continued to set torpedoes by dropping 7-8 alchemist’s bombs. Before that heavenly demon knight approached them, another 100 m long section of watercourse had been collapsed with another boom.

In this case, that heavenly demon knight was driven berserk.

Who could imagine that there was such a weirdo like Zhang Tie in this world? Besides moving as fast as a heavenly demon knight, he also carried a portable space-teleportation equipment. Importantly, he dropped alchemist’s bombs like dropping cheap white cabbages.

At this moment, even though Yan Feiqing didn’t feel like doing that, she could only allow Zhang Tie to pull her forward. Just now, this woman was giving out cold air all over; however, at this moment, Zhang Tie had felt that this woman’s body turned increasingly hotter. Whereas, Zhang Tie didn’t care about that. No matter what, he could cure her as long as she was not dead. Additionally, given her look, she would not die for the time being.

Yan Feiqing served as Zhang Tie’s guide while Zhang Tie was responsible for moving forward at a high speed. Furthermore, whenever he entered a new watercourse, he would drop 7-8 alchemists’ bombs and destroy it, causing so many obstructions and difficulties for that heavenly demon knight.

When Zhang Tie destroyed the 5th watercourse, he had not been able to hear the berserk roars of the heavenly demon knight. However, Zhang Tie was still not reassured. Not until he ruined 5 more did he stop dropping alchemist’s bombs.

After half an hour, under the guidance of Yan Feiqing, they flew out of an underground saltwater ocean and entered a bizarre underground space.

The moment Zhang Tie caught sight of that underground space, he had widely opened his mouth.

The underground space was covered with clusters of huge crystal which were always longer than 100 m. It was like a crystal wood and an urban crystal plaza.
