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..."

Times passed as they rode on the train.

In the era of civilization, travelers could take out their phones, computers, and entertainment devices to kill time on the long journey.

However, in the wasteland, a few hours felt like years without any electronic devices for entertainment.

Fortunately, only five people were in the carriage to Heaven's Origin. Thus, it was not as crowded as the carriages in front of them.

After a brief awkwardness, the middle-aged woman and the solo passenger came over to pass the time by chatting after learning that Su Mo and Huang Xiaojuan were headed to Hope City.

The identities of the two were revealed after some small talk.

The middle-aged woman named Huang Qing was not originally a couple on earth with Gong Liang but formed a family together in the wasteland after joining Heaven's Origin.

The two were rescued from foreign troops during Year 4 of the Doomsday Calendar.
