Zhang Sheng planned for a total of five hundred and twelve Immortal Swords, each level and position having a predetermined number, not randomly cultivated. Missing any one of them means a deficiency in the Dao path, no matter how insignificant, it remains a flaw.
After the Dao Heart shattered, to restore it and tread a more powerful and challenging Immortal Path, how difficult is that, Wei Yuan knew all too well. He understood that if Zhang Sheng's Dao Heart had any blemish again this time, it might never be recovered again, thus the Immortal Path would be cut off, unable to pass beyond the Dharma Image.
Twice in succession, the journey on the Path to Heaven was interrupted midway; whichever way it is interpreted, it's the Heaven's Will. However, with the Ancestor Witch orchestrating, and the Sky Witch as the pawn, it could also be considered Heaven's Will.
Therefore, upon seeing Zhang Sheng's Dao Sword, Wei Yuan realized that he had no choice at all.
