The peculiarity of this dragon was in its location: Luan's brain. Brain protection was most crucial for a cultivator. Most organs could be replaced, but not the brain. Any damage to it would mean death, so Luan prioritized increasing brain defense. The presence of this "evil" dragon further reinforced the protection of the brain region, including mental defense.
"Urghhh..."
Luan had no time to contemplate the situation much, as any distraction increased his pain. More than half of the needles had already been absorbed. It's worth mentioning that these needles were made of natural crystals, highly valuable and incredibly nutritious for the body and Qi when assimilated.
With a roar, Luan assumed his most enhanced form. He now had fangs even sharper than those of a beast, claws more powerful than those of a Fifth Order bear, and white scaly feet reminiscent of dragon scales.
