Simon understood that one mana crystal of grade [1] wasn't enough for him to level up. He needed at least hundreds of them to even level up once.
With a glance, he could see approximately 40-50 crystals growing in each of the twenty or so trees of mana crystals. These trees were still in their sapling stage and with time and adequate mystical energy, their growth might produce more of these crystals and even some higher grades.
Not to mention there was still Cecilia whose powers was like a mystery to him and might even induce some more changes like these in the future.
"Honestly, even I'm impressed by what this girl can do at her age. These mana crystals although they are only grade [1], they are still useful to you at this stage. There are more than 900 of these mana crystals and it seems that the numbers would go up every month. With these, you can gain a few levels".
Irene stated as if reading his inner thoughts.
