Xia Country, Tai City.
The moment Zhou Yi's Blood Infant clone stepped out of the house, the system's voice sounded.
Ding!" Congratulations to the host for leaving home alone. The reward is one point of spiritual power…"
A little bit of spiritual power was useless to the current Zhou Yi, even if he stole it a hundred times.
He looked up at his surroundings. In the distant sky, there were all kinds of immortal carriages, immortal chariots, and people flying in the air. This place looked like a paradise on earth.
"The place you live is a little remote.”
Looking from afar, one could feel the prosperity of Tai City, but also from the suburbs, one could feel that there seemed to be some distance between this place and the city.
"There's still more than ten days before the mysterious person summons the Vengeance Black Slaughter Society.”
Zhou Yi had memorized the map of Tai City by heart. Although he had not gone out since he was born, he knew every street and alley in Tai City like the back of his hand because of his photographic memory and powerful spatial understanding.
Zhou Yi came prepared this time.
"I've checked the envelope for my mother online. It should be produced by Brilliant Paper. There are a total of twelve places in Tai City that sell this kind of letter paper.”Zhou Yi thought to himself. He was prepared to use his terrifying reverse deduction ability to find the person who sent the letter.
" The messenger stuffed the letter into the door. This means that it's not a post office worker. The official will put it in the mailbox or send it to the owner of the house…Then, the messenger might be the mysterious person or someone hired by the mysterious person…"
"The contents of the letter indicate that You-Know-Who gathered many people who had been harmed by the Black Kill Society, so at least he sent more than one letter.”
After knowing so many clues, Zhou Yi smiled.
"At this time, the importance of knowledge is revealed. The tracking technique I learned can be put to use.”
The tracking technique was not rare. It could be learned in the fifth grade of primary school. Not only did Zhou Yi learn it, but more importantly, his understanding of immortal numbers far exceeded ordinary people!
Even the lowest-level tracking technique was comparable to the high-level tracking technique.
"Let's start with the place where the letter is sold!”
Zhou Yi could confirm that the letter was produced in Tai City. He prepared to check the twelve places where it was sold.
……
Time passed slowly.
After about half a day, Zhou Yi stopped at an immortal shop in the center of Tai City.
"Did you buy it here?"
After entering the shop, Zhou Yi stopped in front of a pile of letters. His eyes were filled with spiritual energy fluctuations. This was a sign that he was using a tracking technique.
Through investigation and analysis, especially with the help of the tracking technique, Zhou Yi had already determined that a large number of letters had been sold here, and they had been bought by one person.
"The tracking technique can distinguish the characteristics of spiritual power…It's easy to tell if someone bought a lot of letters. I might be able to find the person who bought the letters by tracking the characteristics of spiritual power.”
The characteristics of spiritual energy were also called spirituality.
Not only did Zhou Yi learn it, but he also understood it. He understood that everyone's spiritual power in this world had its own characteristics, and where it stopped, it would definitely leave traces of spiritual power.
The tracking technique was actually an immortal technique that tracked the traces of spiritual energy.
Just as Zhou Yi was about to turn around and leave, he suddenly saw a young girl and the boss behind him come to the place where he was standing just now.
"Boss, this is the letter paper. Are you sure that a customer has bought a large number of letters recently?”
"Of course," The boss nodded." I'm a law-abiding citizen. I definitely won't lie to the people from the anti-crime squad."”
"Thank you, Boss." The girl frowned after she finished speaking." This is troublesome. Fang Mu isn't here. His high-grade tracking technique might be useful. No, it shouldn't be useful even if he comes. Although he cultivates high-grade tracking techniques, his skills aren't good enough. He can't accurately distinguish the characteristics of spiritual energy. If we expect him to distinguish the characteristics of the spiritual energy of the person who bought a large number of letters and track him down, there's basically no hope.”
"Unfortunately, there are too few people who are good at tracking and have this ability. There are too few people who cultivate this kind of obscure and difficult magic technique.”
As the young lady muttered to herself, Zhou Yi stopped in his tracks.
Is it difficult to distinguish the characteristics of spiritual energy? Difficult to be accurate? The young girl's words made Zhou Yi feel a little strange…Wasn't this super simple? However, on second thought, it was normal. After all, what seemed simple to him might seem as difficult as ascending to the heavens to others.
However, the girl's words caught his attention.
The girl seemed to want to hire someone?
Zhou Yi didn't mind being hired. Han Yue 'er and Zhou Wu's wedding anniversary was coming up, and Zhou Yi wanted to give them some gifts, but he didn't have the money…
"This woman is from the Black Assassination Group, a subsidiary organization of the government. It seems that she is also investigating the mysterious person of the Black Assassination Group. There is no risk in cooperating.”
Thinking of this, Zhou Yi walked in front of the girl and glanced at her work card. Her name was Xin Yu!
"Commander Xin Yu, do you want to hire someone who is good at tracking? I happen to be slightly proficient in tracking.”Zhou Yi suddenly opened his mouth and gave Xin Yu a fright. However, she quickly regained her composure and looked at Zhou Yi.
"You eavesdropped on me?" Xin Yu's tone was unfriendly.
"Coincidence." Zhou Yi smiled.
"Are you good at tracking?" Xin Yu asked expectantly.
"I know a thing or two."
"Then tell me, has this letter been sold in large quantities recently?”Xin Yu asked.
"Not many people have bought this letter recently. The highest number of people bought sixty-one letters in one go, and the second highest number only bought three letters.”Zhou Yi said calmly.
Xin Yu looked at the shop owner and the shop owner revealed a surprised expression,"How do you know that at most, someone bought sixty-one letters at a time?”
"According to the characteristics of Spiritual Energy." "It's very easy for people who are good at tracking to distinguish the characteristics of spiritual power," Zhou Yi said indifferently.”
Xin Yu revealed a shocked expression. The person in front of her really seemed to have some skills?
"Can you track that person's whereabouts through the characteristics of Spiritual Energy?”Xin Yu had some anticipation.
"Sure, this is the basic skill." Zhou Yi replied.
Basic skills? Xin Yu felt that this person was being very humble. After all, even Fang Mu, who was skilled in high-level tracking techniques, couldn't tell the difference so clearly. She probably didn't expect Zhou Yi to be talking about basic skills…
The immortal techniques that Zhou Yi knew had all comprehended the essence of them…Although they were only elementary level basic immortal techniques, after comprehending the essence, they were stronger than high-level immortal techniques of the same type.
"My name is Xin Yu, and I'm representing the Black Gang to hire you!”
"Then we should talk about the commission.”
