Eating the Immortal Grass

In the Celestial Dipper Palace, the First Elder looked at Pavilion Master Kui Xiao and said, "Even though the Sevenstar Immortal Grass is the treasure of our sect, it has quite an eccentric temperament. It doesn't even pay much heed to you even though you are the head of our Sevenstar Pavilion. Is it possible that it will make a move on Elder Liu?"

The Sevenstar Immortal Grass had been around since the founding of the sect, and it had lived for several thousand years since then. Its long life had resulted in its haughty personality, such that it would not show much respect even toward the sect leader of each generation.

Considering how young Elder Liu was, as well as the fact that his cultivation was only at the Heavenly True Immortal realm, would the immortal grass make things difficult for him?
