Time passed quickly. Lin Bei reached a certain point in the ruin challenge in the Sword Tomb Mystic Realm.
"I've already swept through all the Monarch-tier Sword Spirit ruins in the Spirit Sword Domain. Next, I'm going to challenge the Extraordinary Sword Spirit ruins."
Lin Bei stopped and fell into deep thought.
Extraordinary Sword Spirits were a hundred times stronger than Monarch-tier Sword Spirits. Not to mention anything else, just the difficulty of the three-star clone challenge had increased by more than a little.
It was still very difficult for Lin Bei to obtain the Extraordinary evaluation of the four-star and five-star challenges. However, the challenges below the four-star level in the Monarch-tier Sword Spirit Ruins were still quite promising.
Actually, as long as he was willing and spent enough time, he could obtain the Extraordinary evaluation of the 1-star, 2-star, and 3-star challenges.
