"I get it, Little Genius. A phone watch."
"Don't worry, I won't kill you. Tony really was in the wrong about that. I'll teach him a lesson for you later."
"But you should know what the things you're doing mean. I'll give you a dignified end."
With no room to resist, Killian handed over the hard drive and the refrigerated stock solution.
The hard drive contained every experimental log, from the first-generation virus to the current improved version.
It also held all the raw data on human genetic matching and side-effect mutations.
Rimuru didn't execute him. Instead, he used magic to alter his memories.
He erased all of Killian's research memories related to the Extremis Virus.
He left only ordinary memories of starting a business and going about his daily life, completely stripping him of his research abilities.
From then on, Killian would be nothing more than an ordinary down-and-out businessman.
He would never again be able to develop any high-risk genetic viruses.
The threat had been completely eliminated without Rimuru having to bear a murder charge, saving him both worry and trouble.
When he returned to his private research villa, it was only four in the morning, and the sky was still dark.
He sat at the lab bench and examined the underlying genetic sequence of the Extremis Virus.
The more he read, the more he regretted how badly the original had been misused.
Killian had been so focused on combat enhancement that he'd gotten his priorities completely backward.
At its core, the Extremis Virus was a technology for unlimited telomere repair.
It could forcibly repair damaged genes, regenerate necrotic nerves, and reconstruct missing or damaged bones.
Spontaneous combustion and emotional rampages were merely side effects of imperfect genetic rejection.
All he had to do was delete the segment
