In the northern city of Piston City, Yuki practiced hacking into a device that looked like electronic garbage.
This was already a part slightly more advanced than basic programming knowledge.
Virus, decompiling, intrusion, cracking...
These were the most primitive and initial states of Inner Strength.
The earliest Inner Strength was developed greatly in terms of offense. It was only as the enemy gradually mastered the technology that the Heroes began to develop the defensive aspects of Inner Strength.
The junk was assembled by Solo Kill King from some electronic components he found after locating this base, including a simple program. Yuki's task was to bypass the security restrictions and strip the source code of that small program.
The young boy felt exhilarated as he attempted this kind of thing for the first time.
Meanwhile, a little girl sat beside him, biting her finger.
Half an hour later, Yuki felt dizzy and his vision blurred.
He then stopped.
