With doubts about the filthy Yin Qi, Li Ji'an followed Yuanbao True Monarch into the middle layer of the Secret Realm.
The moment they passed through the outer layer's stone gate, a wave of far denser filthy Yin Qi rolled over them, tangibly entwining their limbs and bones.
This Yin Qi was no longer the elusive probing of the outer layer, but rather had a clear erosive quality, infiltrating their nostrils with each breath, skimming their throats with an icy sting, even traveling slowly through their meridians, attempting to penetrate the Dantian and Sea of Consciousness.
Compared to the outer layer, the concentration of Yin Qi in the middle layer had at least doubled, yet it still posed no substantial threat to Li Ji'an and Yuanbao True Monarch.
Li Ji'an's brow furrowed slightly, as the Nascent Soul Primordial Spirit abruptly activated in his Sea of Consciousness, forming a pale golden shield that completely blocked all the invading Yin Qi outside his body.
