Once all the treasures had been introduced, Shen Bing had made up his mind.
To be honest, Shen Bing did not particularly care about the treasures themselves. Unless they were something like the Skyflying Shuttle, which could be a tremendous help to him in the Immortal Realm, he could take or leave most of them.
His most important criterion was how useful and valuable the technology extracted from a treasure would be to him in the real world.
