The seal could not hold any longer.
Chen Mo stared at the Scouter.
Eighty-five billion.
Ninety billion.
The two Cell Jrs. were no longer pink.
Black-red scales emerged across their skin, and Shadow Dragon bone spines grew from their backs.
Their eyes turned red, their pupils glowing.
"They're evolving," Android 18 said.
"It's fusion," Chen Mo said. "Cell's cells and the Shadow Dragons' Negative Energy are eroding each other."
On the Scouter, the Underworld seal's energy reading dropped to its critical threshold.
In three more minutes, the seal would collapse.
