Its own material is made of the strongest alloy known to mankind, even in the face of the sun's first-class heat of stars, or extremely icy environments.
And this Vast Sky City on the Desolate Battlefield was made by humans using endless power.
Not to mention its thickness of one kilometer, there are also large and complex rune formations on and inside, which makes it a first-level existence of a divine weapon.
In the research of Hanyu Xiaotian during this period of time, the power of these rune formations on Haotian City, I am afraid that at least it will not be inferior to Huaxia's seventh-grade super artifact...
.......
"It's no wonder that alien races can't enter Haotian City... Such a huge seventh-rank super artifact... I am afraid that it is much stronger than our Hanyu family's town clan's seventh-rank magic weapon, right?"
"In this case, if the truly terrifying existences of alien races cannot enter the barren battlefield, they should indeed be unable to break this Vast Sky City..."
In the process of repairing and carving runes, Hanyu Xiaotian felt that the powerful power contained in the Haotian City was probably much stronger than the power of herself and the five chiefs.
This is beyond the power range of the ground level, and its power is shocking, or it is impossible to become a base camp for humans to rely on and contend against foreign races...
...
"Such a huge artifact, how powerful it must be... Huh? Could it be... an alien crystal..."
Han Yu Xiaotian couldn't help but brighten up when he thought of something in his mind.
For more than three hundred years, humans have fought with different races and have accumulated countless spiritual crystals, and these spiritual crystals containing incomparable pure power are definitely the best energy source for driving such a huge super artifact.
And only the high-purity energy crystals like the Spirit Crystals of other worlds can spur a huge formation like the Vast Sky City to exert endless mighty power.
This is like the principle of using the energy elementary stone to stimulate the Qi Pavilion and the Tibetan Scripture Pavilion in the Hanyu family.
Moreover, under the urging of millions or even tens of millions of spirit crystals, Han Yu Xiaotian could imagine what kind of vast power the Vast Sky City could exert.
I'm afraid~
It's not as simple as an ordinary Seven-Rank artifact...
...
"How many spirit crystals have to be consumed to spur such a huge super artifact, Vast Sky City...I am really blind. Well, it would be fine if I were Vast Sky City..."
In the regretful sigh, Han Yu Xiaotian unexpectedly had a hope that he was the Vast Sky City. In that case, he could'eat' countless spirit crystals.
However, I sighed, but Han Yu Xiaotian also understood that, facing that terrifying creature in another world that was far beyond the human side, only a super artifact of the level of Haotian City could hold it.
After expressing his emotions, Hanyu Xiaotian again began to expand again. His "Wicked Rune Master" is a very rich career...
At the same time, Wang Ruoqi, Gu Su Xiaoxiao and others, who were at ease because of Han Yu Xiaotian's return, also began to follow the rune masters of the Rune Temple to continue to portray runes and repair the gods.
As for the purple emperor, black dragon and others, they began to conduct deep retreats, integrating the martial arts they had learned in the deserted battlefield into a furnace, in order to truly reach a new level...
