At Blue Star, in addition to his leisurely college life, Ye Qingxuan would also go to Longhu Mountain to work part-time as a Celestial Master from time to time.
On this day, he was attending class as usual, when suddenly a large group of heavily armed policemen rushed into the classroom.
"Ye Qingxuan, right? The situation is urgent, please come with us!"
 In the police station, the SWAT captain spread the information in his hand on the table with a solemn face:
　　　Why do you always go to Longhu Mountain when you have nothing to do? "
Ye Qingxuan replied calmly: "Part-time job."
“My classmates all work part-time at convenience stores, so why do you go to Longhu Mountain part-time?”
 “I don’t get paid to be a Taoist priest at the foot of the mountain.”
The SWAT captain's head was buzzing: "Then why does the contemporary Celestial Master have the same name as you?"
“Master insists on teaching me, so I have no choice but to accept...”
"Three days ago, there were thunders and storms on Longhu Mountain. Was it your fault?!"
"Well, the monsters under the mountain are making strange moves, so I'll take action to deter them."
Ye Qingxuan answered honestly, but found that everyone in the room was silent.
 The leader of the National Security Council took a deep breath after being confused: "Heavenly Master, dare I ask how to kill the demon?!"
  …
It is said that before the contemporary Celestial Master of Longhu Mountain came down from the mountain, all ghosts were free.
 After the contemporary Heavenly Master comes down from the mountain——
“Liu Captain, what are you talking nonsense to this monster? Pindao has already blown away her ancestral graves.”
“If the benefactor cannot understand Dao Zang’s words, I know a little about thunder!”
　　　『Fuso female ghost! Put your hair up!』
Seeing this situation, the entire network was shocked:
“Taoist Priest, you still say you are not an immortal!”
Countries: "How can we fight this? The Heavenly Masters of Longhu Mountain are comparable to humanoid nuclear weapons!"
