However, now sleepiness is coming, and the slave is looking at Zhang Yifeng as if he is looking at his long-lost relative.
An unreasonable sense of trust arose from the bottom of his heart, and he subconsciously handed the token into Zhang Yifeng's hands.
Looking at the token handed over by the servant, Zhang Yifeng's eyes flashed with surprise, and he quickly reached out and took the token.
Unexpectedly, he just didn't want this slave to stay in the steward's palace and spoil his affairs, but instead obtained the token by accident.
In this way, Zhang Yifeng can move freely in the palace of officials.
With a deep look in his eyes, Zhang Yifeng watched the servant leave the side hall.
After pondering for a moment, Zhang Yifeng changed his appearance to that of a slave and prepared to act using his appearance.
After walking out of the side hall, Zhang Yifeng just asked about the structure of the office hall, and the most important thing was where Lei Ling's study was.
Now that he had found out where the study was, Zhang Yifeng moved without any hindrance and easily arrived at the door of Lei Ling's study.
There are not many guards in the entire Secretary Hall, because Lei Ling's Secretary Hall is deep inside the inner gate of the Lei Department.
Naturally, there is no need to worry about any outside thieves sneaking in, so Lei Ling does not need guards or the like at all.
All that is needed to enter and exit each room is the token given to Zhang Yifeng by the slave earlier.
According to the method given by the slave, Zhang Yifeng posted the token on the study door.
Immediately, there was a bright light on the token, and the study door opened by itself without Zhang Yifeng pushing it with his own hands.
Zhang Yifeng did not rush into the study, but first spread out his spiritual consciousness and checked whether there were any formations or traps in the study to guard against outsiders.
Sure enough, with Lei Ling's cautious character, how could he only set up such a defensive measure?
I saw that almost every one or two steps behind the study door, there would be an identity verification formation, unless it was Lei Ling himself or his aura that he had entered in advance.
Otherwise, once someone breaks into the study without authorization, the alarm will be triggered instantly and sound throughout the entire mine.
At that time, Zhang Yifeng will not be able to leave here. There are many masters in the Lei Department's inner sect, and they can easily lock Zhang Yifeng's aura.
Fortunately, Zhang Yifeng is now wearing the disguise of a slave.
On a daily basis, the study and other rooms need to be taken care of by slaves. Naturally, the aura of the slaves is recorded in the formation by the thunder spirit.
But even so, Zhang Yifeng couldn't easily rest assured. With a frown, Zhang Yifeng chose the safest method.
Although it will take a little longer, at least Zhang Yifeng's next actions will not be too dangerous.
After thinking about it, Zhang Yifeng activated his spiritual energy and began to invade the formation that Lei Ling had set up in the study.
Lei Ling's formation was obviously arranged by himself. Even though it was crude, it was not something that would stump Zhang Yifeng.
With Zhang Yifeng's formation genius level, it is not difficult to break the formations laid out by Lei Ling.
The only thing is that there are too many formations in this study, and Zhang Yifeng has to crack them one after another quickly, which takes a long time.
Time passed bit by bit, and Zhang Yifeng finally assimilated the last formation.
Even if Zhang Yifeng reveals his true aura in Lei Ling's study, there is no need to worry about touching the formation.
Taking back the spiritual energy wandering in the study, Zhang Yifeng stepped into it.
Just using the erosion formation technique, Zhang Yifeng also checked the general situation in the study.
From the various layouts in the study room, Zhang Yifeng really found something wrong, which seemed like a suitable location for setting up a mechanism.
It's really shocking that people still use such things as mechanisms in the fairy world.
But in the fairy world, it is safer to use mechanisms to hide items.
After all, if you use formations or barriers to cover items, there is a possibility that they will be detected by divine consciousness.
But if you rely on mechanisms and special materials, it can be as effective as ordinary bricks and stones in isolating the monks' spiritual consciousness.
Therefore, in most cases, using mechanisms to hide items is much safer than using formations and barriers.
After thinking about it, Zhang Yifeng began to test each position he suspected one by one.
Finally, under Zhang Yifeng's deliberate exploration, he found a mechanism on the bookshelf.
Simply opening a mechanism does not seem to be enough to reveal the secrets Lei Ling has carefully buried.
Then, after several attempts from Zhang Yifeng, all the mechanisms in Lei Ling's study were activated.
During this period, Zhang Yifeng only made a wrong order once, and since then he has not missed a single order.
Zhang Yifeng can maintain such a high degree of accuracy because he has extremely firm beliefs in his heart. Even when faced with a choice, he will find little clues in every inch.
When the last mechanism was opened, there was a clicking sound inside the bookshelf where Zhang Yifeng found the mechanism first.
Immediately, the bookcase moved forward slightly, and Zhang Yifeng realized that the bookshelf seemed to be pushable.
Narrowing his eyes slightly, Zhang Yifeng stepped forward and gently pushed the bookshelf.
Suddenly, a gloomy secret passage appeared in front of Zhang Yifeng, and a cold wind kept blowing from the secret passage.
The dim road, coupled with the constant cold wind, is really a bit penetrating.
Zhang Yifeng didn't feel much about this. He had seen a lot of ghosts, but he was still afraid of this evil wind.
As he walked down the secret passage, a spiritual light appeared in Zhang Yifeng's hand, illuminating the road ahead for him.
At the same time, Zhang Yifeng's consciousness was always open to prevent any changes ahead.
For example, Lei Ling, a cautious guy, arranged some formations at the end of this secret passage.
However, all the way to the end, Zhang Yifeng's consciousness did not detect any formation or anything blocking his way.
It is probably that Lei Ling himself felt that it was very troublesome to make too many arrangements in the secret passage, so he simply did not make any more formations.
Of course, the main reason may be that Lei Ling is worried that if he arranges the formation in the secret passage, it will be inspected by someone who is interested.
As the saying goes, a cautious person like Lei Ling should think this way.
At the end of the secret passage is a small room, and the dark wind that blows out from time to time comes from small openings extending in all directions in the room.
The place where these small mouths finally gathered was on the table in the room. It can be seen that the thunder spirit hidden in the secret room under the room turned out to be an intelligence gathering point.
Looking at the spiritual papers that had gathered on the table, Zhang Yifeng narrowed his eyes slightly and stepped forward to open the spiritual papers.
The pieces of spiritual paper were opened, and Zhang Yifeng couldn't help but feel shocked when he looked at the words written on them.
"Hey, this Lei Bu is actually doing this kind of thing secretly, it's really disgusting!"
