Feng Jingyu's explanation, after all, is only verbal and slightly pale.
Only after stepping into the Taixu Illusionary Realm does Han Yi truly feel the way he will enter the Cave Heaven.
Years ago, during the first Cave Heaven trial, he heard a rumor that cultivators who entered the Cave Heaven possessed an immortal body, and all hundred disciples who initially embarked on the journey returned to the sect safe and sound, indicating that the Cave Heaven trial is not dangerous.
In reality, this is indeed the case.
The Taixu Illusionary Realm is located within Yujing Lake, and it connects with Facing Reality Heavenly Realm, so Yujing Lake is essentially the entrance to the Cave Heaven.
And Yujing Lake, located within the sacred grounds of Yujing Mountain, holds a special status. Around it, there must be many high-level cultivators sitting in town. It seemed that their landing was unhindered, but in reality, they must have been under countless people's watchful eyes.
