"What? A Great Dao hidden injury?!"
Yuanshi immediately cried out, looking incredulously at Laozi beside him.
As a Sage, Yuanshi knew all too well what a Great Dao hidden injury meant.
At their level, ordinary injuries to the physical body counted for nothing.
Even if their Dao Bodies were blasted apart, they could regenerate from a drop of blood.
Even if both body and soul were annihilated, they could be reborn through the Heavenly Dao Void.
Jieyin and Zhunti were the best proof of that.
A Great Dao hidden injury, however, was an injury that penetrated deep into one's own Origin Dao Foundation.
In other words, it was as though a crack had appeared in Laozi's Sage Dao foundation.
Such an injury was exceedingly difficult to heal.

More importantly, with a Great Dao hidden injury afflicting him, any further advancement would become harder than scaling the heavens for Laozi-perhaps even impossible.
It was easy to imagine just how terrifying this Great Dao hidden injury was!
No wonder Laozi and Yuanshi were so shocked.
Laozi's expression was utterly grim, and an unmistakable trace of horror had even appeared in his eyes.

The most important thing was to restore Laozi's condition.
Yuanshi turned his palm over,
