Maintaining Demon Deterrence requires continuous communication with the Demon's Heart.
Every time Zong Shen communicates with the Demon's Heart, his blood pressure starts to surge, and his blood flow speed increases.
If Zong Shen's constitution were not strong enough now, he wouldn't be able to maintain Demon Deterrence continuously for even a few minutes.
An ordinary person might not be able to bear its surging pumping force as soon as they communicate with the Demon's Heart, which is very likely to cause blood vessels to burst, putting a great load on the body.
However, Zong Shen can endure it for now, but he can't sustain it for too long at a time; every few minutes, he has to release the Demon Deterrence state to let his body recover.
Zong Shen took off his battle helmet, took a deep breath, and tied the new captive Wailing Lich and the previous one at the entrance of Zhang Zihao's Lord's Courtyard.
