During the period from fifty to sixty years old, Yu An was very busy, this period can be said to be his golden age, with the gradual accumulation of experience and experience, Yu An, who showed amazing wisdom and strategy when he was young, and when he was close to retirement age, he almost rarely studied the skills of using spiritual abilities to fight, and he put more attention on the study of all the supernatural things in this world, and gradually became a consultant-like role.

As a result, the number of peers who came to him for help increased, and he basically did not refuse to come, like an avid mathematician who would only continue to be interested in the face of a constant stream of difficult problems.

Whether it is those difficult and famous big events, or some small cases from private commissions, you can see Yu Anna's wise figure appearing, many amazing achievements and some inevitable failures are the result of this long period of continuous work.

And today, what Xue Ling is about to say is undoubtedly one of the most dramatic.

"For the previous two months, every seven days, he would appear at a place where souls gather, hospitals, cemeteries, or funeral facilities, in short, if he made a move, all the souls in that place would disappear in an instant. He leaves no traces, he doesn't hurt the living, and it's clear that the target is those souls. ”

Yu An thought for a while: "You just said, 'At least my father thinks it's destruction'?" ”

Xue Ling pushed her thick glasses: "I do have a different opinion, I think those ghosts were not destroyed, but 'taken away'. ”

"Do you mean to die or to be captured by a magic weapon?" Yu Andao.

Xue Ling said: "No, I think, it is to use spiritual ability to imprison or transfer the soul." ”

Yu An nodded and said: "Regarding your father's judgment, I can understand that within the coverage of spiritual consciousness, a large number of souls suddenly disappeared, and the first reaction must be that some powerful person has eliminated these souls at one time, because the procedure of overtaking a large group of ghosts at the same time is very complicated, so the situation of passing away should not exist." And this inference of yours is very peculiar, and listening to your tone, it seems that there is a certain basis. ”

"I have no basis." Xue Ling replied very frankly.

"Oh?" Yu An didn't expect the other party to say this; "Then why don't you agree with your father's judgment?"

"Intuition, my psychic powers, provide me with a super-intuition beyond the ordinary, and after going to every event, I have a feeling that those souls are not dead...... They still exist somewhere in the world. ”

"Well......" Yu An fell into deep thought, the clue of this incident is almost none, and people have said it, leaving no trace......

There are people dying every day in this world, even if only 5% of them will become earthbound spirits, and 1% of people will become unjust ghosts, that is also a very considerable number, these ghosts, the ghost hunting world will not deliberately care, after all, you have overtaken them today, and a batch will die tomorrow, moreover, most of the earthbound spirits are harmless, just like those in the cemetery in the north of the city, at most come out at night to scare and scare passers-by, and when they encounter that kind of nerves, they have no spiritual sense at all, and people don't feel anything.

Therefore, there are actually quite a few such soul gathering places, and if that actor never shows his feet, I'm afraid no one will be able to find him.

After a long time, Yu An spoke: "At present, you can't make any assertions, if the truth is what your father thinks, that person's strength will definitely be among the first-class masters, after all...... Even if it is to bind the sky and blade the sea, it is necessary to make some movement to kill ghosts on a large scale, and it is very difficult to leave no traces of them......"

Xue Ling nodded in agreement.

Yu An continued: "And if that person used spiritual power to instantly transfer a large number of ghosts, the question becomes - why? What does he want these souls for? At this time, Yu An suddenly thought of another question, and he said, "By the way, how do you know that there is only one actor?" Wouldn't it be a lot of people doing it together? ”

"It's spiritual sense, my father has confirmed that when a large number of souls disappear under his detection, in that short period of time, you can sense the spiritual power of the giver, maybe he deliberately hides himself in normal times, but at the moment of the shot, it is inevitable to be exposed, even if there are many people who act with him, but there is only one person who directly causes the disappearance of a large number of souls, and there are no other powerful souls around."

Yu An raised his head and quickly made a list in his mind, all of them were spiritual powers, these people could destroy a large number of souls with their own strength, or even the power of a single blow, or transfer a large number of souls.

But there are obviously not many names on this list, and it seems that none of them would do so here and now......

The reasoning has reached an impasse, and Yu An often sighs at this time, "I am old, and my brain is not as flexible as before." Six years later, when a young man named Gu Chen joined the ghost hunting world, Yu An never mentioned this sentence again, he was afraid that the faceless and skinless boy would come up and reply proudly: "Of course, it's my time now!" ”

However, at this moment, he still sighed so long, Xue Ling had no choice but to say goodbye first, and let this senior think about it alone.

…………

A few hours later, it was already midnight, and Yu An still made no progress after the long exam, so he decided to put the case aside for the time being, and wait for new clues to make a decision.

He glanced at the wall clock on the wall, and suddenly thought that his apprentice had gone out in the afternoon, and he hadn't come back yet, and there was no spiritual sense in the room next door, Yu An also used the backup key to open the door and go in to confirm with his own eyes that Shui Yungu was indeed not there.

Fortunately, Emperor Song's old man's spiritual sense is not weak, and it is not a big problem to cover the whole city, so he searched intently, not worried about what will happen to this little Yama, but to see where this kid who didn't return home at night ran.

Who knew that when he checked, he happened to notice that there was a rather powerful spiritual ability in the cemetery in the north of the city, and then, all the souls around him disappeared......
