The reason is quite simple.
Chen Ming is a Psychic, and at the same time, a researcher with a rather complex research focus.
Although he hasn't systematically studied psychic powers, he is not lacking in understanding of them.
Moreover, he knows people who work at the Spiritual Ability Research Institute.
Therefore, Chen Ming is absolutely clear about the nature of the Eros Spiritual Stone.
Even if the Legion Commander doesn't know whether Chen Ming understands the effects of the Eros Spiritual Stone.
When he presented the gift, Chen Ming, without even touching it, had already seen the unique effects of the Spiritual Stone, understood the Legion Commander's intent and expressed gratitude—these are signs that Chen Ming is knowledgeable.
Moreover.
Chen Ming doesn't just have one valuable item with psychic qualities, many people know this.
