The Demon King's avatar controlled by the system was very important to Tang Zhen. He must firmly control it.
If he allowed the system to do as it pleased, it would seriously affect his future plans and might even cause a lot of unnecessary trouble.
Therefore, when he was refining the bone corrosion scroll, Tang Zhen had deliberately held back a trick. When the system was about to show signs of demonization, it would give a timely warning and wake up.
Tang Zhen had obtained the strongest exorcism Scripture from the old monk, which could be used at the critical moment.
The exorcism Sutra was indeed effective. However, in the blink of an eye, the system had regained its senses.
The huge Demon King was chanting the exorcism Scriptures, which reverberated in the wilderness like a Bell.
After hearing the exorcism Sutra, the demons around them were stunned.
To demons, the exorcism Sutra was extremely lethal and would cause them serious harm.
