Regarding the new efficacy after the modification of the Seven Extremes Magic Remains, An Zhen True Monarch was already aware during the modification by seven Nascent Souls in the Artifact Refining Department.
Recreating phenomena such as solar explosions and high temperatures with Immortal Path technology doesn't seem surprising to An Zhen True Monarch.
After all, the sun above the Kunxu Second Floor, known as the Sun Patrol Crow, was constructed by Wanfa University.
Compared to the Sun Patrol Crow, the Immortal Dao Sun in Zhang Yu's hand is still far inferior.
If the Sun Patrol Crow is a real sun, then the Immortal Dao Sun in Zhang Yu's hand is merely a small fireball.
Although both essentially recreate the sun using Immortal Path technology, the power, sustainability, controllability, and impact range differ by countless magnitudes, and the technical content naturally varies vastly.
