Three days later, the Dark Iron Fort...

A streamer-like figure flies in the sky of the Black Iron Fort at a terrifying speed. The speed of that figure is so fast that if standing close up, it has been completely incapable of being caught by the naked eye. Only from a distance can you see a trace. The thin gray lines looming in the sky crossed the sky...

"Boom..." With a sound, there seemed to be thunder light across the sky. On the ground where the figure flew, a bare stone hill of more than 50 meters high was bombarded and cracked by the thunder light. Like an arrow, it spread to the surrounding area. The small mountain bag after the explosion left only a huge hole with a depth of more than ten meters in the ground.

"Boom..." "Boom..." "Boom..."

The thunder-like rumbling sounded continuously. With the loud noise, the high and low underground mountain bags with flying shadows like a streamer were exploded one after another, leaving huge on the ground. In the deep hole, the flying figure is almost like a supersonic bomber, just flying through the sky, he ploughed a huge trace on the ground.

Heller, Edward, Forrest and Aziz stood on a peak of the sacred mountain of the Black Iron Fort, looking at the ravaged scene of the land more than 20 kilometers away.

That piece of land was newly formed in the Black Iron Fortress in the past two days. It is next to the sacred mountain. The total area of ​​the land is 2,000 square kilometers and the surface thickness is 1,000 meters. It was specially generated to give Zhang Tie in the Black Iron Fortress. A training venue for tempering combat skills within.

With Zhang Tie’s current combat power, ordinary combat skills can naturally be tempered in the realm of soul catastrophe, but combat skills such as kinetic energy attacks, especially when special flying spears are needed, cannot be in the realm of soul catastrophe. After completing this kind of training in the realm of soul catastrophe, he could not find a blacksmith in the realm of soul catastrophe to build out the flying spear he needs and then use it for training experiments. Although it is theoretically feasible to do so, but Zhang Tie’s time, It is not used for such consumption.

In the Black Iron Fort, the mountain is picturesque and beautiful. Zhang Tie naturally can’t do damage on the mountain, and within the range of the mountain, there are many people living in it. The people in the Iron Fort have already regarded the Black Iron Fort as their home. The so-called do not do to others what you do not want to do. Even if the Black Iron Fort is his own, Zhang Tie does not want to use it on the homeland and land that others cherish. Tempered his combat skills and messed up the surface.

Taking into account various factors, after a lapse of several years, the Black Iron Fort has ushered in a new space and terrain generation and transformation within these two days.

This process, in the eyes of the residents in the Black Iron Fort, was another demonstration of their god's ability to create the world again.

After the elemental abyss of the Black Iron Fortress opened up the element absorption channel with the element world, the endless elemental energy in the element world continued to pour into the Black Iron Fortress. After four months of absorption, the Black Iron Fortress is now The basic energy reserves of the fort are already sufficient to support an unprecedented terrain and space expansion and transformation of the Black Iron Fort.

This time, the space and terrain transformation of the Black Iron Fort is indeed unprecedented.

The elemental abyss now converts the basic energy reserves every month, which can generate 900 square kilometers of land with a crust thickness of 50,000 meters for the Black Iron Fort. If such a thick crust is not needed, the thickness of the crust can be changed to 200 meters. In other words, the land area it can generate every month can reach 225,000 square kilometers.

After discussing and calculating with Heller, the newly added land and water area of ​​the Black Iron Fort this time reached more than 180,000 square kilometers.

You know, before this, the total area of ​​the Black Iron Fort was only 4000 square kilometers. This time, Zhang Tie directly increased the total area of ​​the Black Iron Fort by more than forty times, nearly fifty times.

In addition to the increase in land area, the average thickness of the crust of the Black Iron Fort has also changed from 200 meters before to 1,000 meters now. In the 1,000-meter crust, 500 meters above are fertile soil layers and 500 meters below. Rice is a layer of hard rock, and the entire Black Iron Fort has become thicker and dignified.

The surface area of ​​the ground has increased forty to fifty times, and the thickness of the crust has increased five times. Such a change is indeed an earth-shaking change for the Black Iron Fort.

In addition to increasing the surface area, Zhang Tie also added an ocean of more than 20,000 square kilometers to the east of the Black Iron Fort in the newly added 180,000 square kilometers of land and water area. Appearing, the surface form of the Black Iron Fort has become more complete. The current Black Iron Fort is already a place with land and sea, and it is no longer the simple land before. Although the ocean of the Black Iron Fort seems to be a little smaller now, it may be more appropriate as a saltwater lake, but for Zhang Tie, the more important thing is that this small ocean can already become the Black Iron Fort The breeding base of all marine plants in it makes the Black Iron Fort even more vibrant.

Among the newly generated land this time, naturally also included this exclusive training field with a radius of 2,000 square kilometers, which Zhang Tie deliberately created at the foot of the mountain.

If you look down from the sacred mountain, the 2000 square kilometer training field is a barren land with no grass. This area is undulating and intertwined with ravines, like a chessboard. It is densely covered with large and small high and low stone hills. And the mound, in nature, it is absolutely impossible to see such a terrain, and such a terrain has become the best place for Zhang Tie to test and train his combat skills.

At this moment, Zhang Tie was testing the strength of his kinetic attack.

Compared with the sledgehammer test in the realm of soul catastrophe three days ago, Zhang Tie at this time fully demonstrated the more terrifying side of kinetic combat skills.

The speed of Zhang Tie wearing Chaos Armor in the sky at this moment has reached 4,478 meters per second. At this speed, Zhang Tie held the newly created fly in the Black Iron Fort that he held in his hand for the past two days. The spear was thrown out.

The flying spear weighing 680 kilograms left Zhang Tie’s grasp at a speed of nearly 1,600 meters per second, and the speed instantly reached more than 6 kilometers per second, such as a flame of fire and lightning, and it hits in a tenth of a second. On the ground below, the kinetic energy of nearly 12.9 billion joules instantly exploded a huge pit with a diameter of more than 30 meters and a depth of more than 70 meters on the ground. The invisible supersonic shock wave shook the surrounding area within 500 meters like waves. The ups and downs, the dust was flying, and then it fell again. Many stones within a few tens of meters around the big hole were shattered and shattered...

Throwing out the last flying spear in his hand, Zhang Tie let out a long roar, his figure flickered in the air a few times, and he came to the mountain peak where the people of Heller were.

"Congratulations, Lord Lord, for the first achievement of kinetic combat skills!" Heller and Edward bent down towards Zhang Tie together.
