Fear

The first 3 months after speaking the oath, Alex spent his days thinking about what he should and shouldn't do. He kept wanting to think of ways to get out of this place, but his oath forced him to stay.

The moment he even thought of leaving without healing the old man, a feeling of suffocation would fall onto him, trying to choke him out of breath and kill him.

Fortunately, his oath had nothing about him having to try his best to heal the old man, or he would be forced to use his real cultivation base when fighting the pill clouds.

Just for his own survival, 2 times in the 3 months, he had already brought forth another 2 pill clouds. However, the weak cultivation base he was portraying could not stop the lightning, resulting in both the pill and cauldron being destroyed each time.

The old man always got mad when he saw Alex fail, but there was nothing he could really do about it as Alex was still weak, so he let it be.
