Chapitre 432: Crystal Orb

Time flew by, and before long, the day turned to night. 

Ellis was first stunned, then frustrated, and later on, impressed at Grey's obsession with trying to figure out how the array in the passageway worked. 

He had seen people who wanted to learn, but few were at Grey's level of diligence. He had been studying Grey's expression over the past five hours, and he could tell that he made some improvements. 

Well, it's not from his expression, but from the fact that he walked into the first part of the array and it didn't light up. It was only after almost a minute did it light up. 

Presently, Grey was already midway through the entire passageway, and it hasn't lit up. When he passed it previously, he used his strength to forcibly suppress it, hence the reason he was able to casually walk through it. But Grey was carefully studying and finding the weak links in the array, this is why it wasn't lightning up even after so long.
