Chapter 2861

The war fortress invented by the United States of mankind is the most powerful war machine specially designed to explore new planets and fight against alien creatures.

Its material is made of the strongest alloy known to mankind, even in the face of the first-class heat of stars like the sun, or extremely cold environment.

And in the desolate battlefield of this Haotian City, is the use of endless human power.

Its thickness is up to one kilometer, not to mention, there are also various large and complex Fuwen array on the top and inside, which makes it become the existence of artifact level.

In the research of Hanyu Xiaotian during this period of time, I'm afraid that the power of these talismans array in Haotian city is not inferior to the Qipin super artifact of China...

...

"it's no wonder that foreigners can't enter Haotian city... Such a huge Qipin super artifact... I'm afraid it's much stronger than the seven grade magic weapons of our Han Yu family?"

"In this case, if the truly terrifying alien beings can't enter the desolate battlefield, they can't really break the Haotian city..."

in the process of repairing and depicting the runes, Han Yu Xiaotian feels that the powerful power contained in the Haotian city is much stronger than that of himself and the five chief ministers.

This is beyond the power range of the earth level. Its power is amazing. Otherwise, it can not become a base for human beings to rely on to fight against other races...

...

"how powerful must such a huge artifact be driven by such a powerful force? Is it... The Spirit Crystal of a foreign race...

what comes to mind? Han Yu laughs at the sky.

For more than 300 years, human beings have accumulated a large number of spirit crystals in the war with other nations. These crystal spirits with extremely pure power are absolutely the best energy to drive such a huge super artifact.

And only the high-purity energy crystal of the alien world can stimulate the giant array like Haotiancheng to play an endless force of heaven and earth.

This is just like the principle of using the energy yuan stone to activate Qi Pavilion, Tibetan Scripture Pavilion and other artifacts in the Hanyu family.

And driven by millions or even tens of millions of crystals, Hanyu Xiaotian can imagine what kind of vast power Haotian city can produce.

I'm afraid that ~

is no longer as simple as the ordinary seven level artifact...

...

"how many spirit crystals should be consumed to motivate such a huge super artifact Haotian city? It's really blind. Well, it would be nice if I were Haotian city...

it's a pity that hanyu Xiaotian has a hope that he is Haotian city. In that way, he can "eat" countless spiritual crystals.

However, Han Yu Xiaotian also knows that only Haotiancheng, a super artifact of this level, can defend itself in the face of the terrifying alien creatures far beyond the human side.

After expressing his feelings, Hanyu Xiaotian began to expand again. His profession of "demon Rune master" has a lot of money....

at the same time, Wang Ruoqi, Gusu Xiaoxiao and others who came down to earth because of Hanyu Xiaotian's return also began to depict talisman and repair magic weapons with the Fuwen masters in the Fuwen temple.

As for Zihuang, Heilong and others, they started to close the door in depth, and combined the martial arts they had learned in the desolate battlefield into one furnace, so as to really reach a higher level
