Using the Void Spirit Body to manage an Immortal Position and operate a Divine Position, while the true body cultivates in the Emperor's Mansion, is a very worthwhile endeavor.
Zhang Jian is not the only one who would take it easy.
In the Three Primal Spirit Official Hall, other Emperors also use Incense Fire Golden Bodies condensed into Divine Position incarnations to station there, while their true bodies have long roamed to unknown places.
Unless it's an occasion like the Great Dynasty Meeting they previously participated in, it is very rare for other Emperors and Ancient Immortals to reveal their true forms.
Of course, using incarnations to handle things does not mean negligence.
On the contrary, all changes remain under the control of the Immortals' true bodies.
Zhang Jian's Void Spirit Body is no less formidable than an Incense Fire Golden Body; in fact, it is even more 'real.' If necessary, Zhang Jian can use it as a nexus point to directly descend in his true form.
