Over the next two days, Rod had mostly spent his time in the sewers.
Clearing the sewers had become routine for him, and he could solve most problems with a Spirit Gun. In rare troublesome cases, he just needed to use an additional Thunder Stone.
Moreover, Rod's combat skills and basic abilities had far surpassed those of the past. Not only had his travelling speed increased significantly, but he also no longer feared sudden dangers.
It's no exaggeration to say that on the upper layer of the sewers, he could easily walk sideways.
Therefore, Rod's already high cleaning efficiency improved dramatically once again, and the soul strength of 2430, coupled with the enhancement from his Spiritual Energy, rendered him invincible.
Moreover, Rod discovered that the Soul Strength seemed to also enhance the Eye of the Soul. It was clear that, originally, his ability to see through physical objects was only 7-8 yards, but now it had extended to 10 yards.
