Chapter 251: A Thunderous Strike is a Must!

Half an hour later, Lin Yun had placed both devices in position and activated them.

"Two devices, total of one thousand six hundred spirit crystals, can gather resources worth about three hundred spirit crystals each day..." Lin Yun broke the surface of the water, remounted his flying car, and said softly.

This was the result of his calculations.

Every day, he was getting nearly a five to one return, which even surpassed what he gained from the professional device that absorbed and refined spiritual energy and produced spirit crystals.

Moreover, the collection devices he had bought weren't even high-end. If he had bought more advanced collection devices, his returns would be even larger.

Of course, the resources found by these detection devices weren't particularly abundant. If he changed to more advanced collection devices, he would quickly exhaust those resources and need to change locations frequently.
