How to display a numbered list (li) from top to bottom in one block horizontally?

Question

css

Hello! Need help masters of sword and magic html and css!
Please help me to make this numbered list:
ul_1
li_item_1 li_item_5 li_item_9
li_item_2 li_item_6 li_item_10
li_item_3 li_item_7 li_item_11
li_item_4 li_item_8
li_item_12 I need to display the block in a single list in this order without dividing it into blocks.
To be honest, even for Google I can’t formulate the question correctly, all the time heresy is issued.
Thanks to all!
