National Interstellar Survival: I Upgrade My Spaceship by Being Stingy

The gamma-ray burst arrived at Earth 72 hours later. The atmosphere was stripped away, seawater was boiled dry, and all carbon-based organisms on the surface were wiped out. Humanity has devoted all its efforts across the globe to build 10,000 fire arks. Each ship carries 100,000 people and is the last hope for all mankind. Lin Mo didn't get a ticket, but only picked up a defective ship that was rejected during quality inspection—— Pin Xixi number. Other people's arks are streamlined space swans, and his ships are tin cans with patches on them. Others have a load of 100,000 people, but his ship has a discount of 50,000 people. It was 372 kilograms overweight before takeoff. The engineer was so anxious that he was sweating and couldn't fly. Lin Mo smiled. A god-level picker in the 22nd century, charges are based on the gram. Three hundred and seventy-two kilograms? That's it? [The god-level picking system is successfully bound! Since then, there has been an outrageous and outrageous ark in the universe. Armor too thick? After cutting off seven centimeters, the weight was reduced, but the strength increased by 37%! Engine wastes fuel? Eighteen tons of waste parts were removed, the thrust was quadrupled, and the fuel consumption was cut in half! Can't the shield hold up? Turn off the 360-degree global defense and change it to a cone-shaped precision shield, which will triple the power! Not enough food? The ecological cabin is dug three times from beginning to end, and the production capacity is tripled, directly realizing a material closed loop! Other captains: "Does a broken ship deserve to be called an ark? If it falls apart, don't hurt us!" Pin Xixi started from the 10,000th place and rushed all the way to the top 100.
