Cultivating the Little Five Thunder Skill doesn't necessarily require one to be drenched in the rain.
But when practicing this technique, at the very least, lightning and thunder within sight must be visible.
Staying inside a military tent, the surroundings are too well shielded.
One can hear the thunder roaring, but the lightning flickering in the sky is completely obscured from view.
In such a setting, it's not that cultivating the Little Five Thunder Skill is entirely impossible, but the efficiency would be extremely poor.
If Chen Hai were in the city, finding a place that could shelter from the rain and still allow a view of the lightning and thunder in the sky wouldn't be difficult.
Not to mention other locations, just the small pavilion in the courtyard of his West Mountain Villa would suffice.
However, at the moment, this was a wilderness.
To return to the city from here would take two to three hours by car.
