Castle of Black Iron

The huge sword in Zhang Tie's hand was called Devouring Dragon, the largest and heaviest silver secret item that Zhang Tie gained from the Weapons Mountain except for Thor's Hammer.

Devouring Dragon was 3.46 m in length, as wide as a threshold and as thick as 20 cm. After being manifested, it weighed 2,700 kg and could easily cut gold, jade and iron. Additionally, the sword carried two powerful striking effects: super great sharpness and blade storm. This sword was another version of the "man's certificate" that Zhang Tie used before. It was definitely a rarity even among silver secret items.

It was his first time to use this sword since he gained it. This time, Zhang Tie used the blood of an earth demon knight to activate it...

During the 6 decades in the tower of time, through so many times' combat simulation with Yan Feiqing, Zhang Tie's kinetic strike skill had long entered an immortal realm. With Devouring Dragon in hand, he could kill earth demon knights easily like chopping melons and vegetables.

As Devouring Dragon was lighter than Thor's Hammer, the energy of kinetic energy carried by DevouringDragon was less than half of that of Thor's Hammer. However, on the battlefield; especially in large-scale chaotic battle, Devouring Dragon was more destructive than Thor's Hammer.

Why?

Because Thor's Hammer attacked its enemy using its flat side; however, Devouring Dragon attacked the opponent using its sharp blade. The force area of Thor's Hammer was many times that of the blade of Devouring Dragon. In this case, even the energy of kinetic strike carried by Devouring Dragon was less than a half of that of Thor's Hammer, its blade would cause greater stress and destruction to the opponent's protective battle qi and body within a unit area. Plus its super great sharpness effect, how could the protective battle qi of an earth knight resist Zhang Tie's marvelous "inch strength" skill in close combat?

When the Devouring Dragon split open its protective battle qi and cut off its body, the earth demon knight had already been shattered into pieces by the blade storm effect of Devouring Dragon. It didn't know what had happened until it died.

Being a bit late than Zhang Tie, soon after Feng Cangwu dodged away from a battle qi strike of a demon knight and was approaching a black iron demon knight had he seen how Zhang Tie got such a terrifying huge sword out of the void and shattered an earth demon knight into pieces in a split second. Feng Cangwu was really startled by what he saw. 'F*ck, is that a motherf*cking man? Did that demon knight make any preparation or it's just a coincidence...'

Since he had a fight with Zhang Tie in the trouble-reappearance ball in the incarnation of a demon fighter, Feng Cangwu had known that there was a difference between him and Zhang Tie on battle strength. However, he had not imagined that this difference was so irreparable. 'What the hell! That's impossible...'

After killing that earth ox-head demon knight at such a transient moment, Zhang Tie's battle intention surged at once. By killing demons, he would save humans. To kill one demon knight meant to save tens of thousands of people. Zhang Tie felt that he had returned to the former Iron-Blood Camp as he was fighting demonized puppets by the "man's certificate" together with his brothers.

"Go die..." Zhang Tie roared as he flashed and slashed his longsword towards the head of a black iron iron-armored demon knight. In a split second, the iron-armored demon knight's protective battle qi was cut open while its head was sent flying off. At the same time, Zhang Tie activated the effect of blade storm and shattered the entire iron-armored demon knight together with its armor.

In less than one minute, Zhang Tie had already killed two demon knights. After noticing that at the corner of his eyes, Feng Cangwu immediately gave up contending with Zhang Tie. 'What the hell! What a man...'

With Devouring Sword in hand, Zhang Tie roared as he flashed into the demon knights which were as thick as huckleberries in terms of a sharp sword light. Singing a song loudly, he started to slash demons...

"What is more frustrating and dismal is the departure, not to mention that northeast and southwest is so far away from each other. When the moss has just put forth in spring, the autumn wind has risen. Therefore, people leaving their hometown would feel desolate..."

The familiar lyrics flew out of Zhang Tie's mouth, which couldn't be covered by the battle calls on the battlefield. Being different than that when he sang it for his junior sister apprentices in Hidden Dragon Island at the beginning, this time, this song was filled with dismal and sad feeling. At this moment, even though the lyrics remained unchanged, they sounded especially heroic, imposing, frank and heart-wrenching...

After the word "dismal", Zhang Tie's Devouring Dragon had turned into a sword qi hurricane which involved 4 black iron wing demon knights inside, though they were hundreds of meters away from him. After the word "desolate", the four black iron wing demon knights had been shattered into pieces by Zhang Tie's sword qi, leaving blood mist in the air...

"Go die..." An earth demon knight brandished its huge black saber towards Zhang Tie with an air-splitting killing saber intent.

This earth demon knight was an iron-armored demon knight, whose battle strength was indeed much greater than the first earth ox-head demon knight that Zhang Tie had just killed.

"The wuthering wind sounds different than usual. The undulating clouds presented a bizarre color. Ships stagnate near the bank. Vehicles became hesitate beside mountain path. How could oars be pushed forward? Horses are neighing forlornly."

In the song, Zhang Tie's DevouringDragon vibrated and rang. Zhang Tie combined with his sword and broke the strong saber qi face to face. He split the saber qi into halves using his sword while resisting the cutting of the opposite saber qi. In a split second, he had pushed to the front of the earth demon knight.

"The sunbeams on the wall gradually disappear. The clear and bright moonlight spray over the corridor. The red orchid holds autumn dew. The green catalpa is covered with thin frost..."

After the word "disappear", the hug saber in the hand of the earth demon knight had been broken by Zhang Tie's Devouring Dragon. Closely after the word "Corridor", blood had spurted out of the place between its thumb and index finger while half of its handle flew out of its hand. Soon after the word "dew", one arm of the earth demon knight had been broken by Zhang Tie. The earth demon knight was so scared that it wanted to escape; however, after Zhang Tie finished the word "frost", the former fierce earth demon knight had turned into blood mist as it diffused like frost...

It was the 2nd earth demon knight that Zhang Tie had killed on this battlefield...

'Parents travel across the old rooms and close the doors. They stroke the brocade curtain and feel cold and dismal. After their sons leave home, they often dream about their sons lingering around them and guess that their sons' souls are wandering after departure.'

At this moment, a 3-in-1 formation of 3 earth demon knights besieged Zhang Tie while Zhang Tie's sword light flashed in a confident and elusive way...

When Zhang Tie killed the second earth demon knight, all the 100,000 more human and demon knights from Xuanyuan Fortress and demon battlefortress moved their eyes onto him at the same time...

On the battlefield, Zhang Tie's sword light and song were like a bright moon in the evening and a morning huge sun which lit up the bank of Weishui River, the main battlefield of the holy war...
