Castle of Black Iron

In the dense demonic qi over the sky, Zhang Tie reached out his finger. Closely after that, a tiny golden flame appeared on his finger. Then, the golden flame became longer than 3 m in the shape of a dragon. After that, the dragon-shaped flame grew longer and bigger. In a few seconds, it had become a giant dragon longer than 100 m. Circling around Zhang Tie, it constantly devoured the black demonic qi beside Zhang Tie. Then, many colorful fire dragons and snakes separated from this giant fire dragon like fission. One for two; two for four; four for eight...

Only after a short while, there were already tens of billions of colorful fire dragons and fire snakes within thousands of miles. When they connected with each other, they formed a terrifying fire ocean and over 60 miles-thick fire clouds. As long as the demonic qi that came out of Demon Deity"s Abyss touched the flame, it would disperse immediately like ice or snow entering a steelmaking furnace.

It was an ocean of chakra flame.

Those fire dragons and fire snakes were the original looks of chakra flames. Such a fierce flame could burn up almost the entire King Roc which had eaten numerous dragons in the universe except for its heart.

The original looks of chakra flames didn"t manifest until Zhang Tie formed his first immortal chakra. By then, the chakra flame that Zhang Tie formed was more than tens times more powerful than that when he promoted to a sage knight.

Zhang Tie then flew into Demon Deity"s Abyss with the endless chakra flames.

The chakra flames that Zhang Tie released could just cover the entire Demon Deity"s Abyss. Zhang Tie flew downwards leisurely along with the 6,000 miles long chakra flames in an overwhelming manner...

Facing the terrifying chakra flames, the demonic qi inside Demon Deity"s Abyss was burned up and dispersed. Meanwhile, those demons" nests on the cliffs were being melted and batches of demons flew out of the dense ma.s.s of nests in a flurried way. However, before these demons figured out what happened, they had been caught in the chakra flames and turned into ashes. 

Some demons" nests were very deep. Additionally, the tunnels inside their nests were very complex. Those chakra flames in shape of dragons and snakes flew into those nests and burned everything along the sinuous maze-like route. Before Zhang Tie"s arrival, his fire dragons or fire snakes had already spurted out of the nests below. 

Almost none of the demons could survive Zhang Tie"s chakra flames. Tens of thousands of demon generals and ordinary demon soldiers would turn into ashes per second. Even supreme immortal demon generals had been devoured by Zhang Tie"s chakra flames when Zhang Tie was 10,000 m away from them.

Wherever Zhang Tie pa.s.sed by, not a single demon would survive. The cliffs of Demon Deity"s Abyss were completely meltdown like candles as their surface turned as smooth as silk. The surface of the overall Demon Deity"s Abyss changed greatly.

There were relatively more demons and demon nests left near the entrance of Demon Deity"s Abyss on the top. When Zhang Tie reached increasingly deeper, he found the effect of his lightning strikes became more and more evident and fewer demons could survive. 

Zhang Tie didn"t even calculate how many demons had turned into ashes all the way from the top to the bottom of Demon Deity"s Abyss; because it was definitely an enormous figure. 

The entire Demon Deity"s Abyss was deeper than 20,000 miles. When Zhang Tie reached its bottom, the night had fallen.

 The original topography at the bottom of Demon Deity"s Abyss couldn"t be seen at all. When Zhang Tie came here with overwhelming chakra flames, he found the bottom of Demon Deity"s Abyss was like h.e.l.l. It was steaming everywhere. Not a single demon could be seen here. Additionally, he saw over 100 huge basin-like pits here evenly. Those huge pits were filled with scorching magma. 

There was a pitch-dark cave on a place thousands of meters high on a cliff. The diameter of the cave was thousands of meters. All the black demonic qi was coming out of that pitch-dark cave. Because the cave was almost vertical to the bottom of Demon Deity"s Abyss, only a part of its entrance was affected by Zhang Tie"s lightning bolts. 

After taking a look at that entrance, Zhang Tie instantly hid his chakra flames and entered that entrance frankly, 60 miles per step. Only after more than 10 steps, he had crossed the 600 miles long cave and came to the deepest place of that cave.

It was a colossal underground karst s.p.a.ce in the deepest place of the cave. A 10,000 m high statue of demon deity with b.l.o.o.d.y eyes, sharp ears, four arms and cattle hoofs was standing inside this underground s.p.a.ce. It was covered with pitch-dark scales. 

This statue was giving out black demonic qi through its mouth constantly. Meanwhile, the last 70,000-80,000 demon generals and Heavens-Reaching Demon Emperor inside the Demon Deity"s Abyss were gathering around the statue and watching Zhang Tie entering here from air leisurely with panic, enmity and despair in their eyes.

Zhang Tie burned down all the way here from the entrance of Demon Deity"s Abyss, sparing no chance for them to escape at all. As a result, they could only gather here and prepared to have a duel with Zhang Tie. 

Heavens-Reaching Demon Emperor was the most powerful ox-head demon. Because of his pair of huge golden horns, he was called Heavens-Reaching Demon Emperor. According to the legend, there were four demon emperors, namely Six-Armed Demon Emperor, Versatile Demon Emperor, Black Mountain Demon Emperor and Heavens-Reaching Demon Emperor. Heavens-Reaching Demon Emperor was the most powerful one among them. As Heavens-Reaching Demon Emperor always defended in Abyss Demon Domain, when humans heard his name, they would become fearful at once. Over 200 years ago, Star Emperor and Force Emperor launched a common attack towards Abyss Demon Domain. Heavens-Reaching Demon Emperor blocked the two human immortal emperor"s common attack alone till the other demon emperors" arrival.

However, no matter how powerful this demon emperor was, he was just an animal in a cage for Zhang Tie.

"Dragon Emperor, Zhang Tie..." Heavens-Reaching Demon Emperor almost squeezed out the four words through his teeth, causing the air in the karst cave to undulate.

Zhang Tie only took a casual glance at Heavens-Reaching Demon Emperor and tens of thousands of demon generals behind him as if they were nothing. Closely after that, he fixated onto that huge statue. The pair of b.l.o.o.d.y, grim eyes with golden pupils of the statue looked familiar. 

Undoubtedly, it should be the statue of the Demon Overlord. It was Zhang Tie"s first time to see Demon Overlord"s look.

When he wanted to return to Taixia Country from Motian Realm in terms of King Roc in the "dream", Zhang Tie only encountered the projection of a pair of eyes and a huge arm of the Demon Overlord in the Chaos s.p.a.ce; instead of his matrix. 

There was a high platform for sacrifice at the foot of this statue, on which was a huge b.l.o.o.d.y pool. The surroundings of the entire b.l.o.o.d.y pool were embedded with human bones. Additionally, there were mountains of human skulls around the b.l.o.o.d.y pool, each of which was higher than 1,000 m. There were hundreds of millions of human skulls. Given the size and volume of those human skulls and bones around the b.l.o.o.d.y pool, Zhang Tie found they belonged to kids; instead of adults.

Demons were offering sacrifice to demon overlord with human kids here. Zhang Tie didn"t know for how many years had they carried out this evil rite.

When Heavens-Reaching Demon Emperor found that he was neglected by Zhang Tie, he roared as he rushed toward Zhang Tie with a mace. He then slashed toward Zhang Tie with his mace from 10,000 m away, arousing a strong battle qi in an overwhelming manner...

However, Zhang Tie disappeared immediately. Before Heavens-Reaching Demon Emperor"s attack arrived, Zhang Tie had already reappeared next to Heavens-Reaching Demon Emperor. At the same time, he went through Heavens-Reaching Demon Emperor"s protective battle qi easily like going through a layer of silk. Under the astonished eyes of Heavens-Reaching Demon Emperor"s, Zhang Tie lightly put his hand on the latter"s head.

"Now that you like to offer sacrifice so much, you should enjoy being sacrificed!" Zhang Tie"s voice reverberated in each demon"s awareness. 

"Ah..." Heavens-Reaching Demon Emperor shrieked. In the blink of an eye, his 2-m high frame had started to shrink and deflate like a balloon. Meanwhile, that pair of golden horns were losing their l.u.s.ter. Finally, his frame collapsed and turned into ashes. The most powerful one in Motian Realm died in Zhang Tie"s hand in this way without any resistance and became the first sacrificial offering with Zhang Tie"s secret skill All of Infinite King Roc Sutra.

It was not that Heavens-Reaching Demon Emperor was not powerful; but that Zhang Tie was much more powerful than him. What Heavens-Reaching Demon Emperor to Zhang Tie was what a toddler to a heavyweight champion in the ring. The former was too weak.

"Kill him." Watching their most powerful one being killed by Zhang Tie with great fear, all the remaining demon generals broke down mentally completely. Before Zhang Tie launched a strike toward them, some demon generals had roared. In an instant, all the remaining demon generals rushed toward Zhang Tie disorderly with furious red eyes. To kill Zhang Tie or to be killed!

Looking straight into the b.l.o.o.d.y eyes of that statue of Demon Overlord, Zhang Tie said, "You"re powerful. Pitifully, you"ve already repelled by all the universal rules in this world. As a result, your matrix couldn"t even enter this world or those neighboring s.p.a.ce. Additionally, none of your descendants or your projections could defeat me. I know that you can see what"s happening here. You should see how I am gonna burn all of your descendants into ashes," Zhang Tie said with a sneer, "From today on, the nightmare will not belong to humans, but demons! If you want wars, I will give you wars..."

After leaving these words, Zhang Tie punched out.

All of a sudden, a sun appeared in the underground karst s.p.a.ce. There was a huge light&shade of golden spike shrimp in the core of the sun.

If not form his immortal chakra, he could not realize the universal rules. Only when he formed his immortal chakra could Zhang Tie release the power of his punch of universal rules.

At this moment, the whole world was quivering.

The windstorm higher than 20 million Celsius degrees devoured everything in the karst cave immediately.

The 70,000-80,000 demon generals who were rus.h.i.+ng toward Zhang Tie...

The colossal statue of Demon Overlord...

The blood pool and the mountains of bones...

All the terrifying, grim and sorrowful things...

All those above were wiped out by Zhang Tie"s punch!

The entire underground karst s.p.a.ce was shattered and disappeared. Meanwhile, a huge s.p.a.ce entrance like that above the core area of Mountain Ruins appeared here.

"h.e.l.ler, let Castle of Black Iron integrate with the s.p.a.ce ball of Motian Realm!"

After leaving a sentence to h.e.l.ler, Zhang Tie entered that s.p.a.ce entrance with one stride.

...

In the weird and unpredictable chaos s.p.a.ce, Zhang Tie was wandering leisurely while being circled with golden light. However, his speed was even faster than that of the king roc in his "dream".

At this moment, the pair of golden pupils reappeared in the black mist in the nihility with infinite fury and fierce qi. Closely after that, the black mist in the nihility formed into the projection of the huge Demon Overlord as same as the statue he saw just now. Meanwhile, the Demon Overlord"s projection punched at Zhang Tie with his four fists.

At this moment, a giant paG.o.da appeared in Zhang Tie"s hand as numerous runes were flowing over its surface. When the giant paG.o.da cast strong light onto the projection of demon overlord in the Chaos s.p.a.ce, it instantly shattered the latter. Meanwhile, the giant paG.o.da"s gate opened and absorbed all the broken black mist.

At the same time, a growl drifted from the Chaotic s.p.a.ce...

...

Not knowing how long had pa.s.sed, Zhang Tie finally saw the s.p.a.ce bubble in his memory in a s.p.a.ce mezzanine of the Chaos s.p.a.ce which was much more complex than a maze. 

When he flew in the s.p.a.ce bubble, he instantly saw a vast brilliant ocean.

Right then, the Infinite Immortal Prison flew out of the mouth of King Roc"s and turned into a huge paG.o.da as high as 600 miles. After that, it opened the gate at its bottom and absorbed the entire ocean before returning to Zhang Tie"s mouth.

...

After absorbing the ocean of energy, the king roc went through heavy black mist and s.p.a.ce mezzanines toward one direction, leaving a streak of golden light...

"Taixia Country, I"m back..."

...
