Castle of Black Iron

Whenever it was, the deep night was always the best protection for all the nocturnal animals.

Few people moved in the evening. Additionally, even if they had night-viewing medicaments, their vision could never match that in the daytime. If it was too far away from the target, the effect of night-viewing medicaments would be greatly discounted.

After using up all the 20-odd water-element crystals in his hand, Zhang Tie opened his eyes. Although it was still windy and snowy outside the mountain cave, it had already been pitch-dark. As the gloomy sky was covered with thick clouds, no starlight could be seen through.

It was time for action.

The huge boa just slept on Zhang Tie's side quietly. Zhang Tie picked himself up as he teleported those empty water-element crystals into Castle of Black Iron. In a split second, he was in the hard and grim armor of Chaos.

Zhang Tie triggered a master-level hiding skill. Closely after that, the pitch-dark Chaos had become looming like the skin of a chameleon, completely integrating its color with the background color of the mountain cave, manifesting the grains of nearby stones.

When Zhang Tie exited the mountain cave, the Chaos changed its color into a dark gray. When the snowflakes fell onto his Chaos, snowflake-shaped spots soon covered over his Chaos.

Being silent, Zhang Tie immediately rushed into the sky from the boulder and reached the cloud over 20,000 m high as fast as a lightning bolt before moving towards the north.

In this case, clouds could prevent him from being discovered.

Zhang Tie could see through the clouds and see things far away by his lotus flower eyes; however, the others couldn't do it.

Zhang Tie moved very fast as he had already triggered his flight ability as a divine dominator. Only after a short while, he had reached 8 times the speed of sound. Benefited from such a high speed, he soon flew across Ningzhou Province and entered the air territory of Huanzhou Province. After passing by Huanzhou Province, Zhang Tie changed his direction and flew towards Helan Mountain Range in the west.

At such a high speed, Zhang Tie was like a specter and a lightning bolt that penetrated through clouds. Even heavenly knights couldn't catch up with him.

Only after a short while, the familiar Helan Mountain Range had appeared under his foot.

Compared to the two banks of Weishui River, Helan Mountain Range was another battlefield. Because Helan Mountain Range had sophisticated terrain, high mountains and dense woods like a huge barrier that lasted thousands of miles, no troop of over 10,000 population could carry out the action in the mountains freely. Additionally, ground forces would find it difficult to move to the mountains. There were many dangerous abysses in the mountain range where even birds couldn't fly across. In this case, demons put their main force to break through Weishui River while only leaving 10 more spider demon corps in Helan Mountain Range and some demon knights in the periphery of Helan Mountain Range.

Helan Mountain Range had become the battlefield of middle and small forces between Taixia Country and demons.

The battles in Helan Mountain were not as mighty and overwhelming as that on banks of Weishui River. However, it was more dangerous for fighters of Taixia Country to attend battles in Helan Mountain Range.

Even at a high altitude, Zhang Tie could still see clearly the sparkles and silent killings in the woods of Helan Mountain Range lasting 600 miles.

The sparkles were caused by incendiary mines and bolts. Killings were undergoing throughout the time. Both parties were trapping and killing each other. Tens of thousands of small units of Hua fighters and demons were crisscrossing and spraying blood over the snow land in Helan Mountain Range.

Zhang Tie flew by Helan Mountain Range and continued to move towards the west.

Although the battlefield at the foot was fierce, it didn't belong to him.

Demons set a floating battlefortress in the west of Helan Mountain Range. Demon Knights were accessing to it. Similarly, Taixia Country set two floating battle fortresses in the east of Helan Mountain Range, confronting with demons.

This place was not far from the main camp of the demon army. Additionally, many demon knights were guarding there. It was not proper for hunting earth demon knights here. Therefore, Zhang Tie rushed over without demur, leaving behind the floating battlefortress of demons.

After flying across Helan Mountain Range, Zhang Tie entered the air territory of Wuzhou Province. At this moment, the entire territory of Wuzhou Province had been collapsed. Zhang Tie kept moving towards the west.

After crossing the frontline of the demon army, Zhang Tie could see a demon camp in every 600 miles. Each demon camp was based on the original city of Taixia Country and contained millions of demon fighters and over 100 demon knights. In case of Hua knights' raid, demon camps were strictly safeguarded. Knights were taking actions in terms of squads, sparing no chance for Zhang Tie.

Last time, Yan Feiqing almost fell in a trap set by demons in such places. Of course, Zhang Tie would not make the same mistake.

In fact, Zhang Tie had long predicted about such a situation. Therefore, he didn't target these demon camps. His target was actually in Yinzhou City. Yinzhou City was once the provincial city of Yinzhou Province and now the "capital" of Heavens Reaching Empire. A band of remnants of Heavens Reaching Church who betrayed Taixia Country and went and sought refuge and honor with demons was ruling the city.

At least half of the 29 earth knights on the ranking list of criminals in Supreme Court of Taixia Country were in Yinzhou City.

Yinzhou City was about 8,000 miles away from Helan Mountain Range.

In addition, Yinzhou City had already been renamed as Heavens Reaching City by the remnants of Heavens Reaching Church.

Zhang Tie flew over demon camps and cities which were occupied by demons one after another. At the speed which was 8 times the speed of sound, it only took him less than 2 hours to arrive at the sky above Yinzhou City.

Yinzhou City was a magnificent Class A city. The entire city was girdled by a demon camp. All the way here, Zhang Tie found that most of the cities occupied by demons were pitch-dark. However, in order to prove the "prosperity" of the capital of Heavens Reaching Empire, the entire city was covered with fluorescent lamps, including the top of city walls. From the sky, Yinzhou City was a bit boisterous.

Squads of demon fighters were patrolling in the city. Whenever those patrolling demon fighters passed by Hua captives, those fraught Hua civilians would hurriedly give way to them as they stood on the roadside...
