"What is that?"
Yu Hong squinted and focused his gaze.
He discovered that it was a circle of dark ashes from the Blackstone Grass.
This circle of ashes encircled the outer edge of the Blackstone Grass like a black ring, surrounding the small garden of grass.
"Is the Evil Shadow eroding the Blackstone Grass?" A faint suspicion arose in Yu Hong's mind.
"So, the Blackstone Grass must have some resistance to this thing," a thought suddenly flashed through his mind.
"That's right! Although I can’t use the Black Seal right now, the Blackstone Grass can recover with internal energy. As long as I continuously activate and nurture the Blackstone Grass, I can indirectly use my internal energy to resist the external Evil Shadows!"
This was not an ideal method, but in the current situation where he couldn't use the Black Seal, nurturing the Blackstone Grass with internal energy could serve as a substitute for the talisman boards, providing a temporary defense against the dangers from outside.
With this thought, Yu Hong felt invigorated.
He placed a single hand on the surface of the Black Seal, and in an instant, a faint connection with the Blackstone Grass appeared in his mind.
He could distinctly feel that through this thread of connection, he could transmit his internal energy over there.
