Doomsday: My magical right hand can store tens of billions of materials

[Apocalypse + stockpiling supplies + space + not the Virgin + killing decisively]
Giant beasts invaded and doomsday came, Zuo Hao found that his right hand had mutated.
All items touched by him can be strengthened.
"You touched a metal warehouse and strengthened it into a super-large warehouse."
I rely on!
Huge space, let’s stock up tens of billions of tons of supplies first.
"You touched a watch and strengthened it into a time-suspended watch."
Time paused.
I can do whatever I want!
"You touched a dog, and your dog turned into a beast."
Is there any king law?
Can even living things be strengthened?
"You touched your own body, and your body became an artifact."
I rely on, really everything can be touched. ...
