Vacuum decay was a true cosmic disaster.
Put simply, it was a process in which the metastable vacuum of the current universe decayed into the true ground-state vacuum through quantum tunneling.
In plain English, it erased everything—energy, matter, and space—then remade them all.
It was also one of the legendary methods of restarting the universe.
Gao Gong had heard that among the "doomsday-level weapons restrictions" signed by the level-nine civilizations, one of them was the cosmic-level "vacuum decay."
But that did not mean "vacuum decay" did not exist outside the level-nine civilizations.
During a "void expedition" like this, spatial energy leaped from low density to high density. In theory, there was a chance of running into "vacuum decay."
But in reality, the probability of this thing appearing was even lower than winning the lottery.
This was the main universe, after all. Who would expect the main universe to suffer cosmic disasters every day?
Even though the vacuum decay before them had not yet reached the legendary "cosmic-scale formatting" stage,
the white line that erased everything had just appeared from the "kaleidoscope" before swallowing half the fleet.
Whether it was Velvey, the Great Void Dweller, or the several fourth-order lifeforms in the fleet, none of them had any power to fight back against a disaster of this level.
In fact, one of the ships enveloped by a white line even contained a fourth-order lifeform—Lady Number 19.
This gravitational-wave lifeform, who had completed a planetary Big Bang, was devoured by the white mark and erased without the slightest ability to resist.
"The legendary power of 404."
Gao Gong frowned deeply. This had not even reached the "vacuum bubble" stage, yet it could easily swallow a fourth-order species.
Would this void expedition be wiped out completely?
Were they really that unlucky?
However, in
