After calculating for a week in the secret room, Lin Yun almost completed a small part of the analysis of the 8th character. He gradually was able to tell that this character was far more powerful than the previous seven. If he succeeded, it would most likely give him a huge strength boost and might even help his Magic Array become more refined.
This discovery immediately made Lin Yun look forward to mastering the 8th character, and eventually all the rest, too.
After all, Lin Yun hadn't found a good opportunity to break through ever since he completed his 5th Magic Array in the prince tomb. Although Lin Yun had gained several tens of thousands of runes, he had yet to find a suitable opportunity to turn these runes into another Magic Array.
