Mental Obstacle

The moment Alex's dantian freed up, a wave of Qi escaped from it, rising directly through his body.

It stopped once near his heart before continuing on its way up to the brain. When it reached the brain, it stopped once more, quickly enriching his mind.

As it did, Alex felt his spiritual sense quickly improve.

This was the point when one's Spiritual sea would open up. However, since Alex had already opened it, the energy instead enriched it, making his spiritual sea far stronger.

Bit by bit, Alex felt his spiritual sense spread throughout the mountain. He could only focus on it partly as the majority of it was still focused on his breakthrough.

His spiritual sense slowly grew from the 900-ish meter range he had managed to get it to in the last year and a half, and quickly reached the 1-kilometer mark.

However, it didn't stop there. It continued growing further and further.

1100 meters, 1200 meters, 1300 meters, and so on.
