Chapter 719: Rejuvenated

The Black Yellow Immortal Spiritual Energy from the Earth Emperor's Book was on the same level as the Emperor Brush's pure Yang Immortal Spiritual Energy. It was naturally going to be extraordinary once in use!

Back then, the Immortal Spiritual Energy from the Emperor Brush allowed the Physique Tempering Stage Three Ling Yun to breakthrough 15 realms and arrive at Qi Cultivation Level Nine!

That six to seven hours gave Ling Yun an endless amount of benefits!

Now, the Emperor Brush seemed to know about Ling Yun being his host. Because Ling Yun wasn't the nicest host, it became stingy and seldom provided Immortal Spiritual Energy for Ling Yun to use.

However, the Earth Emperor's Book seemed to be extremely generous. Up until today, it had released limitless Immortal Spiritual Energy for Ling Yun to absorb three times. Ling Yun was struggling to keep everything in his body, so he was forced to use the spiritual jade box to contain it.
