Well, given Zhang Yanhang's current situation, perhaps it is not easy to encounter Fourth Tier Monsters, and more often he would meet Fourth Tier Awakened. However, as the saying goes, the earlier you upgrade, the earlier you enjoy, and it's always good to be prepared.
In case he was suddenly attacked by a Fourth Tier Monster one day, wouldn't that skill come in handy? Although the probability is frighteningly low.
Therefore, to some extent, compared to the anti-interference ability, which is only effective when facing the rare Fourth Tier Monsters, increasing the Penetration Power is more practical for Zhang Yanhang.
"Now that the Penetration Power has been strengthened again, this means that the range I can scan in the Crimson Iron Ore Vein will definitely increase significantly, which will definitely assist greatly in my subsequent cleanup. It should lead to a very noticeable improvement in my hunting efficiency."
