A thought moved in his heart.
Xuanqing found himself back on the Moon again.
Gazing at the pockmarked surface and various cosmic rays in the air, such a harsh environment would be unbearable for any ordinary person with no cultivation background, even if they were clad in a spacesuit.
To make the Moon suitable for human habitation, the first issue to solve is the cosmic ray one.
"Whether it's cosmic rays or random meteorites, laying down a large formation will easily solve it."
Xuanqing pondered in his heart.
Having said that,
The ozone layer that shields Water Blue Star from cosmic radiation can actually be considered as a naturally formed defensive array.
Soon after,
There was no need for excessive deliberation.
An idea had emerged in Xuanqing's mind and he immediately mumbled in his mind:
"Exchange for a Deus Ex Machina Eight Trigram Furnace!"
