Capítulo 1159: Sneaking in

"Eh? Fang Heng, the one in your hand is..."

Seeing that Fang Heng had successfully controlled the magic array, Sandy was suddenly interested and came over to observe.

"Oh ho? It's a spirit catalyst crystal cube?"

Fang Heng looked at Sandy, "You also recognize it?"

"Yes, yes. I saw it when I was reading books on the third floor."

Sandy looked at the crystal in Fang Heng's hand and nodded, "The book says that the Empire has spent a lot of money on its development, but the one in your hand doesn't seem to be a second-generation product anymore. It's probably the latest generation of scientific research products."

"Do you know why the Empire is developing such a thing?"

Fang Heng thought that they probably didn't have anything like the sacred tree to feed, right?
