Level 5
James had only planted about ten of each seed because if Cassy one day needed more, she could always use the seeds that would automatically be stored in her inventory after all the magic herbs were matured and gave more seeds.
And finally, when all the preparation had been done and James had planted all the magic herbs from level 1 to level 10 while being careful to respect the spaces that everyone had made their own here, he had called Cassy as soon as she had finished making her 5 level 3 magic pills at the same time, and he had given her the special light pill asking her to use Angel's power to help them mature faster.
But Cassy had told him that there was no need for that because everytime she leveled up, all her magic herbs would grow at once thanks to the evolution of her Divine Space.
