Second System Invasion [Progression | LitRPG | Modern London] (Book 1 written!)

The first System invasion reshaped the world. The second destroyed it. For a hundred years, humanity has coexisted with the System. This changed when a Slayer reached level 100, and the System updated. Now, the entire world is a level 100 zone. Most humans died within mere hours. Leo is a veteran Slayer. As one of his classes, he chooses the unique [Royal Astronomer] for its crafting bonuses, but soon discovers that the power of the Cosmos could be far stronger than he anticipated. Now, in the face of humanity’s extinction, this power may just let him create a safe haven for other survivors… or doom what remains of society. With the rules of society gone, old Slayer guilds of London seek to retain their control, no matter the cost. But while Leo tries to fight them off and keep his group safe, he keeps witnessing the System’s cruelty. And so, his distaste for it grows. For a brighter future, the System will have to be struck down.  What to expect: -Strong-to-strongest progression -A brutal world, but where hope still exists -No stat sheets  -Crafting & faction building -Modern London landmarks turned into dungeons -No harem Daily chapters for the first month, then every Tuesday/Friday!
