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..."

'Goodness, the iron boiler and high-efficiency boiler are still understandable, but the alchemy furnace…

Su Mo was tempted when he saw the upgrade routes for the boiler room.

After all, iron seemed much safer in terms of thermal conductivity and maintenance compared to rammed earth.

This was especially true for the later high-efficiency boilers, which could significantly improve the original properties to ensure that the boilers had higher heat conversion efficiency and post-maintenance.

However, Su Mo changed his mind merely five seconds after seeing the words "alchemy furnace".

An alchemy furnace was an indispensable and essential part of the long history of Huaxia!

In the biography of every emperor, there was the shadow of its existence. Even in fairy tales and myths of cultivating immortals, the existence of an alchemy furnace was always included!

Look, Those Hearts are on Fire!
