According to the Monk Emperor's Heart Mirror suggestion, obtaining the Blood Pill means that Zhang Wuji's Blood God Pill within his body can be neutralized. By then, if his powers are fully restored, Jiang Dali believes that resolving Shakyamuni should be much easier.
And even if he cannot kill this resilient, formidable old monster, he should be able to severely wound it again, preventing it from wreaking havoc in the Martial World and posing a threat to him for some time.
In Jiang Dali's notes, once an enemy cannot threaten him in the short term, often after this period, it will no longer threaten him at all.
In fact, ultimately, his determination to deal with Shakyamuni is because Shakyamuni's various insidious and harmful methods have gradually threatened his safety. Even the Eternal Life God, at his strongest, was once trapped, as was Qin Shi Huang of Qin State, deceived by this old dark spirit. He does not believe he can guard against this old dark spirit's tricks.
