They could see it clearly, even with the naked eye.
Beyond this thick layer of the Thunder Sea, below was still a passage...
But this layer of Thunder Sea in between, was like a filter, anyone who entered would have their physical body obliterated there, and only their Remnant Consciousness Whisper would enter.
This was the greatest obstacle.
"Go ahead."
Wang Yuanfan commanded.
"Yes!"
Standing at the entrance was a member of the Heaven's Path Followers, with a Cultivation Base in the early stages of the Gathering Spirit Realm.
He did not transfer his Cultivation Base to a newly prepared body, but instead ensured he was in his most intact state as he charged towards the entrance.
What he sought was authenticity.
So that Lin Yuan could clearly see what fate and accidents would befall a real Cultivator entering.
And such a scenario had happened more than once in these few days.
From the early stages of Qi Refining, middle stages...
All the way to the Divine Sea Realm Peak.
