After all, Li Xinyu and Ming Jiajia did not say that a group of elders really couldn't do anything about them.
After all, they are girls. What can you do? Can't you hang them up and take a leash?
But there must always be an explanation.
Li Xinyu can only vaguely say that she and Ming Jiajia have made such rapid progress, and indeed use some secret methods, but these methods are trade secrets and must not be leaked. As long as you know that these methods really do great help to them, and it's all harmless.
Li Xinyu has always been principled, and the elders have nothing good to do about what she doesn't say.
But they did not have any reason to ask further.
After all, Li Xinyu said that there was a trade secret, and her vitality had increased by 0.4 in two months, and she had no negative impact on her body. If use this gimmick to advertise, let alone 0.4, even if it rises by 0.3 in two months, it is also a lot of people willing to spend money to improve.
