Castle of Black Iron

3 days later, in Castle of Black Iron…

A human flashed in the sky of Castle of Black Iron at a terrifying, high speed like a lightning bolt. People could barely catch his movement by naked eyes even being close to him. Only in the distance could people see a looming grey fine line streaking over the sky…

With a “boom…”, a barren 50-m higher hill was exploded into pieces after the human flashed by, sending broken stones flying about 1,500 m in all directions, leaving a huge hole whose depth and radius were both over 10 m.

“Boom…”, “Boom…”, “Boom…”

The thunder-like explosions sounded one after another. At the same time, those hills at different heights were exploded one after another, leaving many huge and deep holes on the ground. The flying man was like a hypersonic bomber. Wherever he flew over, he would leave a huge, evident trace on the ground.

h.e.l.ler, Edward, Agan and Aziz were standing on the top of a mountain peak of Immortal Mountain in Castle of Black Iron and watching how the land over 10 miles away was spoiled by Zhang Tie"s kinetic energy strikes.

That land was newly formed a couple of days ago right beside the Immortal Mountain. It covered 1,200 square miles and was 1,000 m in thickness. It was taken as the training field for Zhang Tie to practice his battle skills in Castle of Black Iron.

Based on his current battle strength; of course, Zhang Tie could practice common battle skills in trouble-reappearance situations; however, as the battle skill of kinetic energy strike which required special spears couldn"t be trained in trouble-reappearance situations. Whatever, he couldn"t find a blacksmith"s shop in the trouble-reappearance situation and build his spears over there before taking them out for the practice. Although it was feasible theoretically, Zhang Tie didn"t have so much time to do that.

As the Immortal Mountain had a very picturesque scenery, of course, Zhang Tie couldn"t destroy it. After leaving Immortal Mountain, there were many residents. As those residents had already regarded Castle of Black Iron as their home, even though Castle of Black Iron belonged to Zhang Tie, he didn"t expect to practice his battle skill on the land in others" home and spoil the earth surface.

Given those factors, Zhang Tie finally accomplished another s.p.a.ce and terrain formation and modification after so many years.

In the eyes of those residents in Castle of Black Iron, their G.o.d was creating the world once again.

Since the elements abyss connected the elements realm, elements had been constantly flowing into Castle of Black Iron. After 4 months" absorption, the basic energy storage in Castle of Black Iron had been available for an unprecedented terrain and s.p.a.ce expansion.

This s.p.a.ce and terrain modification of Castle of Black Iron was indeed unprecedented.

The basic energy storage converted by elements abyss each month could provide Castle of Black Iron with 540 square miles" land as thick as 50,000 m. If he didn"t need such a thick earth"s crust, 130,000 square miles" land as thick as 200 m could be formed per month in Castle of Black Iron.

After negotiating and calculating with h.e.l.ler, Zhang Tie knew that over 110,000 square miles" water and land area was increased this time.

Before this, the total area of Castle of Black Iron was only 2,400 square miles. This time, Zhang Tie increased the total area of Castle of Black Iron by over 40 times.

Besides the increase in land area, the average thickness of the earth"s crust of Castle of Black Iron also increased from 200 m to 1,000 m. In the 1,000 m thick earth"s crust, the upper half part of the earth"s crust was fertile soil; the lower half part was hard rocks. Therefore, the entire Castle of Black Iron became thicker and steadier.

The earth"s surface increased by 40-50 times; the earth"s crust"s thickness increased by 5 times. What a tremendous change for Castle of Black Iron!

Besides the increase of the earth"s surface area, Zhang Tie increased over 12,000 square miles" ocean in the east of Castle of Black Iron. The appearance of this ocean made the surface landforms of Castle of Black Iron more complete. Castle of Black Iron had contained both land and ocean; instead of being purely land. Although the ocean in Castle of Black Iron was a bit small and was more like a salty lake than an ocean, it could already serve as the base for the reproduction of all the maritime plants in Castle of Black Iron and make Castle of Black Iron more vigorous.

Of course, this new land included the exclusive training field which covered over 1,200 square miles at the foot of the Immortal Mountain.

Looking down from the top of the Immortal Mountain, this training field was completely a barren land. It was crisscrossed with rises and falls like a checkerboard. Additionally, it was covered with dense stone hills and mounds. As the best training field for practicing his battle skill, such a terrain could never be seen in nature.

At this moment, Zhang Tie was testing the power of his kinetic energy strike.

Compared to his trial in the trouble-reappearance situation 3 days ago, Zhang Tie completely displayed the terrifying effect of kinetic energy strike at this moment.

Zhang Tie"s flight speed in the sky could reach 4,478 m/s in Chaos. At such a high speed, he threw out the two spears that he had people made in Castle of Black Iron.

The spear weighing 680 kg left Zhang Tie"s hand at a speed of almost 1,600 m per second and accelerated to greater than 6,000 m per second in a split second. Like a flame and lightning bolt, it hit the ground within 0.1 seconds. The kinetic energy of almost 12.9 billion Joules made a huge pit which was wider than 30 m and deeper than 70 m in a split second. The invisible hypersonic impact wave caused the land within 500 m to rise and fall like ripples and caused dust flying in the air. After the dust fell down, many rocks within dozens of meters were shattered and cracked…

After throwing out the last spear, Zhang Tie roared as he flashed back to the mountain peak where h.e.l.ler and the three servants were standing on.

“Congratulations, Castle Lord, you"ve almost grasped the kinetic energy strike skill!” h.e.l.ler and the other three people bowed towards Zhang Tie at the same time as they said in unison.
