Lier spent almost every second of his time working on a new Second Heart based on Lizard Serum.
He still didn't know what the difference in the flow of time between the two worlds would turn out to be, so he had to hurry and get this thing done.
Overall, its structure was quite simple. It could basically be seen as a minor modification of the original Cyberware.
There weren't many bioplastics to choose from with 2011 technology, but if he did a good enough job, he could hide the small components that would trigger a massive immune response inside the Second Heart.
The design process was complicated, but the real problem was how to carry out the modification:
The Cyberware was directly inside the body, so of course the modification would have to be done inside the body too-but who would perform the surgery?
Lier thought of a way: perform the surgery on himself.
He wouldn't lose consciousness or his reason from the pain of surgery. That was a considerable advantage.
Furthermore, the Spinal Cyberware he had installed was quite advanced. If he handled it well, he could control nearly every nerve in his body.
Preprogram some instructions, then make them into a Behavior Shard and use it to perform the surgery semi-automatically-that was the only solution he could think of.
But that meant he would have to send over the Ripperdoc gloves from the cyberpunk world-
After removing the replaceable tools and extensions, the gloves weighed 500 grams while retaining their full functionality. He had to thank his past self for choosing gloves instead of replacing his entire arm.
Even so, he still didn't have enough Tech Points to spend.
So Lier spent a great deal of time cramming on genetic engineering and working all day in Connors's
