Shakyamuni shook his head slightly when he saw Shen Yuan jumping out from the Saha Flowers and came before him.
He didn't use the Three Lifetimes Karmic Curse. Its effect wasn't very great.
At Shen Yuan's level, the Extreme Spiritual Divine Monkey's Heavenly Eyes and Ears became very powerful. His Heavenly Ears could listen to the matters of the past, while his Heavenly Eyes granted them vision to see the changes of the future.
His understanding of everything reached a rather high level. Even if it couldn't compare to the Buddha's Three Lifetimes Karmic Curse or Lin Feng's Dao Fruit, it was still at a very deep level.
The effect of karma pestering Shen Yuan was very limited. It was unlikely to cause sufficient disturbance to him. Comparatively, it was more effective on Xuan Shang.
That was why Shakyamuni didn't hesitate at all. He unleashed his palm towards Shen Yuan!
