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..."

The Type-80 machine gun had a rate of fire of about 700 rounds per minute, not to mention the rate of fire of the M-1 automatic rifle

If each bullet cost 2 points, then it would cost 1400 survival points per minute. Who could afford such an expense?

"To build my great steel torrent, I must ensure that I have enough ammunition. Otherwise, everything is but empty talk."

"Smokeless gunpowder must be acquired."

On the path to making guns and ammunition, Su Mo had taken 99 steps on this road, with only the last step remaining. Even if he could not get through, he decided that he would have to go hard and, even if he could not push, he would have to push hard.

Adhering to the tradition of the older generation of scientists in China, Su Mo has full confidence in adhering to this aspect.

"Airdrop, airdrop, when will it arrive?"
