There was no doubt that this was the work of inner demons. His inner demons had discerned Chu Yunfan's feelings and triggered the scene that he missed the most. However, Chu Yunfan's heart was firm, so it was impossible for him to be affected by this illusion.
However, since this was what his inner demon brought out, Chu Yunfan faced this problem squarely. After solving it, it did not affect him in the slightest. On the contrary, it made his heart toward the dao even more firm.
For any cultivator, inner demons were a huge problem. In the process of cultivation, they would often encounter all kinds of problems. When these problems accumulated, they would form inner demons.
