In this post-apocalyptic world, 10,000,000 individuals across eight continents have received a strategic-based system granted by the Organizers via a roulette selection. This system allows them to:

  

• Install Extensions – Enhancing their abilities and fortifications.
• Synthesize Weapons – Crafting advanced tools and armaments.
• Create Kingdoms & Fortresses – Establishing dominions by devouring existing infrastructure.
• Devour Materials – Breaking down buildings into sub-particles for immediate use (e.g., metals, wood, cement).
• Bury Zombie Corpses – A necessary step to prevent further contamination.

  Zombies have the ability to infect and mutate animals, making them grow faster, become more toxic, and deadlier.

  Users can level up by:

  

1. Devouring the systems of other users.
2. Fusing their fortresses with those of other system users.

  The leveling system follows exponential growth, requiring double the resources at each stage:

  

• LVL 1 = 100 A-sol
• LVL 2 = 200 A-sol
• LVL 3 = 400 A-sol
• LVL 4 = 800 A-sol

  Zombies follow a similar progression sequence, but at lower values:

  

• Rank 1 Zombie = 10 Sol
• Rank 2 Zombie = 20 Sol
• Rank 3 Zombie = 30 Sol
• Rank 4 Zombie = 40 Sol

  To devour infrastructure faster, users must collapse buildings first. Otherwise, careful deconstruction takes 50x longer to avoid damaging external structures.

  When devouring a building, materials are separated into sub-particles, such as:

  

• Metals (sorted by type and alloys)
• Wood (categorized by species and density)
• Cement, Clay, and Blocks
• Other building materials

  The MC, a campus student, has a unique system that allows him to gain harem members, servants, and workers through copulation. This is because his system requires strategic thinking and the formation of subfactions.

  

• His smartest companion is his girlfriend, who helps him navigate the system's complexities.
• Within the first hundred chapters, most of the surviving women who didn’t die from sickness became part of his harem—excluding those who were fat or unattractive.

  Among the 10,000,000 system users, some individuals hold significant influence:

  With a world population of 16+ billion, the number of deaths within one week from non-zombie-related causes is estimated as follows:

  

• Natural deaths (normal mortality rate): ~2.34 million
• Deaths from societal collapse (lack of medical care, starvation, stress): ~11.69 million
• Asthma-related deaths (without medication or inhalers): ~14.4 million
• Cancer patients (without treatment): ~8 million
• Paralyzed/immobile individuals (without care): ~9.6 million

  Total Non-Zombie Deaths: ~43.69 million

  

• Suicides (despair, hopelessness): ~8 million
• Accidents (fires, infrastructure collapse, vehicle crashes): ~8 million
• Exposure (lack of shelter, dehydration, extreme weather): ~16 million
• Violence (riots, looting, killings in panic): ~32 million

  Total Indirect Deaths: ~64 million

  ~107.69 million deaths in the first week

  This does not include zombie infections, meaning the true death toll would be even higher. Let me know if you need further breakdowns or adjustments!
