My Subordinates Can Grow Stronger Without Limit

[Ancient-Era Transmigration + System + Ensemble Cast + Unlimited Followers + Nation-Building + Power Fantasy] Jiang Linyun transmigrates to an ancient parallel world with no supernatural powers, and awakens a Slaughter System. He can exchange Slaughter Points for weapons for his followers. Whenever one of his subordinates wields a weapon, each person they kill lets them absorb 10% of that person’s attributes, while Jiang Linyun earns 1 Slaughter Point and gains 1% of those attributes. Later, he discovers the weapons do more than boost attributes: they can even restore severed limbs and... increase lifespan! He thinks this will make him invincible, but he never in a million years expected that, even after becoming invincible... people from beyond the heavens would show up! Well, in that case, he’ll just have to borrow a few lives from you all...!!!
