Lin Mu had been close to the peak of the Dao Treading realm for quite some time now and was only waiting for his Dao Embryo to reach the limit. Only when it did would he be able to enter the Immortal ascension realm and be able to sense Immortal Qi.
But Lin Mu had not done that. Instead, the consumption of Immortal Qi rich food had allowed him to obtain Immortal Qi before he even reached the Immortal ascension realm.
Normally, if a cultivator forcefully consumed Immortal Qi in any form, whether it be in the form of beast meat, immortal fruits and herbs, or even immortal pills, it would be useless.
At the best, the immortal Qi would dissipate automatically as their bodies would be incapable of holding it. And at the worst, they would explode from the immortal Qi and die from it.
