章 290: Reverse Freelance Surgery

A bunch of silver white Treasure Chests appeared in front of Ling Ran.

The piles of Treasure Chests covered Ling Ran's entire vision. Once he opened all of them, the light was as brilliant as if fireworks had been lit in front of him.

Ling Ran was not surprised to see many green bottles of Energy Serum. He also calmly accepted the fact that he had obtained two skill books after he opened thirty-one Treasure Chests.

After all, he opened the Treasure Chests once they reached a prime number. There was nothing strange about him receiving skill books at the smallest prime number available—two.

Theoretically, Ling Ran could even accept the setting of receiving thirty-seven skill books from thirty-one Treasure Chests.

"System, please put away the Energy Serum." Ling Ran was indifferent to the appearance of the Energy Serums. After all, he had already accumulated 214 Energy Serums, thus, it did not matter anymore to him ^_^.
