She talking about the Heavenly Spirit Fruit which can allow a low-level Martial King to break through to the rank of a high-level Martial King?
Is this woman completely blind to the circumstances?
We know that a group of spiritual beasts all at the rank of Martial King had been immediately slaughtered by Gu Ruoyun. Her powers have long surpassed the level of a mid-level Martial King. She's probably a high-level Martial King at the very least. She might even be a Martial Emperor...
Would she have that level of power if she were only a mid-level Martial King?
"What do you say, Miss Gu?" Murong Rou'er smiled confidently. She was certain that no cultivator could possibly resist the temptation of a Heavenly Spirit Fruit. "I can give you more time to think about it. Though I believe that you are an intelligent woman, Miss Gu, so you should be aware of what is useful to you! You will never make any stupid decisions!"
