Chapter 520: Fifty

'There should be another way…'

Lin Yun frowned. He examined the energy levels at the five points in the array, considering the problem from all angles. But he didn't know where to start. Time slowly passed, day after day, without any movement in the alchemy laboratory. Lin Yun just remained motionless as he stared at the Dragon Crystals in a daze.

In the end, on the fifteenth day, Lin Yun slowly opened the door to the laboratory, taking a deep breath of fresh air. 'Forcing the energy of the five Dragon Crystals to form a circle isn't as good as fusing them together into one Dragon Crystal to embed in the Doom Staff…'

To be more accurate, he gave up on his previous plan and decided to fuse the five Dragon Crystals instead. However, this also had some issues...

Once he came out of the laboratory, he noticed that Reina wasn't alone. Yuri was also there.

"High Mage Mafa…" Yuri caught sight of Lin Yun and rushed to greet him, looking somewhat worried.
