I'm only three years old, how could it be a world-ending catastrophe?

Three years ago, Jiang Luo transmigrated to this world, becoming a newborn baby and awakening the [Attribute System].
The system told him that the world was dangerous, but he would gain an attribute point for every day he survived.
Jiang Luo believed it and cautiously lived until the 100-day celebration, only to discover that this world was exactly the same as the Blue Star world of his previous life. From history and culture to technological development, even the timeline had not changed, and there was no danger in sight.
This led Jiang Luo to believe that it might be a misaligned system.
However, after his failed attempt to manifest himself in front of others when he was two years old, he realized that the system was completely useless!
Just when Jiang Luo thought he would live a peaceful and uneventful life, a sudden and dangerous event shattered his tranquil existence...
……
"Calamity? Extraordinary beings? Mystery? Ferocious beasts?"
"What the hell?! You damn system, you're actually right?"
Jiang Luo was completely dumbfounded.
