Catty Catty Catty

As disaster was about to strike, a group of survivors transmigrated into a desolated world and were challenged to a game of survival. From terrifying acid rains, to endless natural disasters, the heavens burn while the earth scorches, radiation is rampant, and nobody is spared from the dangers of this hellscape. The only way one survives is by building a shelter and slowly upgrading it in hopes of surviving another day. 
Luckily, Su Mo awoke a Doomsday Survival System that allowed him to infinitely level up and upgrade his shelter! The main shelter wooden door can be upgraded into a metal door, which in turn upgrades into a composite gate; the wooden spears can be upgraded into bronze spears, which eventually upgrade all the way into electromagnetic spears... While everyone struggled to survive, Su Mo was fully loaded, and well equipped to dominate the post-apocalyptic world. 
"While some of us are lighting oil lamps, he's been using refrigerators!" 
"The walls in his shelter alone are tens of meters thick, it's the safest place on this planet."
"Before I die, I wish to spend one day in his shelter..."

A unit of wheat weighed more or less around 0.15 catties. It was not a constant value either.

This was one of the rules of the game panel's calculation system. Some of the wheat had a higher moisture content, so less of it would be weighed. If the moisture content was lower, then more of it would be weighed.

However, in general, based on the ratio after the wheat was ground into flour, nine units of wheat would produce around a catty of flour. This was a sufficient amount of carbohydrates for an adult human's daily activity in the wasteland.

To excavate one unit of iron, a mine was needed. People who were fast enough could excavate 14 units within an hour, whereas the slow ones could only manage 8 to 10 units.

Therefore, as long as one excavated for six hours every day, by calculating based on an average of 10 units, one could obtain 60 units of iron.
