286 A Small Test Run

"This is the all-out effort Gu?"

In the secret room, Wei Yang held this Gu in his hand as he exclaimed, strange light shining in his eyes.

All-out effort Gu, it was shaped like a rhinoceros beetle.

Now, it was sitting quietly in Wei Yang's palm, its body was almost the size of Wei Yang's palm, and was quite heavy.

It was oval in shape, and had a strong armor exoskeleton. There was a strong horn on its head, looking heavy and powerful.

It had three pairs of legs, all strong and thick. Its body was dark brown, and glistened with a metallic surface. People only needed one glance to know it was not ordinary.

"That's right, this is the rank three all-out effort Gu. Once used, it would summon a beast phantom, able to move according to my will." Fang Yuan was sitting on a cushion opposite Wei Yang, as he explained.

Wei Yang breathed in deeply, handing the all-out effort Gu back to Fang Yuan.
