What was the cosmological constant?
General speaking, if multiple universes did exist, a cosmological constant would be the special DNA for a universe. The cosmological constant was what made the universe different from the others.
After arriving at the world, Lucien had found that although this world was very similar to the Earth, there were still a few major differences, for example, the undiscovered stars linking to destiny, the existence of magic, arcana and Blessings, great dragons, demons, vampires and so on. Therefore, Lucien subconsciously took it for granted that this world was in a different universe, thus, of course, the cosmological constant would also be different.
