You Die had no desire to merge her Split Soul with her main soul, because the Split Soul contained a Life Chain.
Though she had been constrained by Lu Ye before, if she truly steeled her heart, she could abandon the Split Soul and free herself from this restraint!
But once they merged, she would never be able to escape that restraint again. Then, she would truly share life and death with Lu Ye!
It was precisely because of this concern that she had tried to reason with Nine Infants just now, unwilling to start any conflict with it.
Yet the outcome was far from ideal. Nine Infants clearly acted as though it had Lu Ye completely in its grasp.
She had also considered simply abandoning Lu Ye. If what Nine Infants said was true, then after discarding her Split Soul, the benefits she could gain would not be small!
But after thinking it over carefully, she decided against it. Leaving aside the fact that Nine Infants had no substantial evidence to prove its claims, even if it were true, she would likely become nothing more than a lackey beneath Nine Infants in the future.
She was, after all, at the Merging Dao Peak. If she were not constrained by this stretch of starry sky, she might not have lacked hope of attaining Dao Harmony. Why should she humble and wrong herself?
Her initial retreat had merely been an act.
Under the Life Chain, she could sense whether Lu Ye was lying, and Lu Ye could naturally sense whether what she said was true.
So when You Die retreated, he knew what she was plotting.
Since the Split Soul's sneak attack had failed, and she could not allow Nine Infants to succeed, there was only one choice before You Die.
