"Huuuu…"
Inhaling deeply, I focused my attention on my muscles. Like a calm well, I immersed myself in my own mind as everything around me disappeared.
It was important for me to take note of the different nerves used throughout my body as I felt every twitch and movement.
"To harden my body completely, I must break the microfibres within my muscles and replace them with stronger ones."
It was just like building muscles.
A person's muscles become stronger and more durable by breaking the microfibers inside of them through exercise and building them again through recovery.
As for me, I intentionally destroyed the micro-givers according to Han Yufei's instructions in order to build them back up, stronger and more durable than before.
By carefully snapping a selected few micro fibers, one would find their body rapidly hardening.
This method had only one drawback, and that was that it required a high level of concentration.
