The sandstorm appeared unusually fast. If Lex was not prepared by designing such a metal house beforehand, everyone would have been exterminated in the sandstorm no matter how powerful they were.
The atmosphere in the room was very tense. Black sand particles pounded the exterior of the metal house. The mages were silently calculating. They were calculating how long the metal in the house could hold out for.
"This is the material used for making the giant shields wielded by the war puppets, with an additional ten-thousandth of copper and two hundred and forty-thousandth of thorium. It has a thickness of half a yard. The innermost layer contains only stainless steel, with a thickness of half a centimeter though." Lex provided the specific details of the metal house.
"If the sandstorm doesn't stop, this house will be able to last for six hours." Saleen was the first to calculate the duration.
