The heart is located on the left side of the chest.

But there are a few people with the right heart.

And if you are not an acquaintance, it is impossible to know about such a thing.

Qin Ran looked in the direction of the door lock again.

There are no signs of being pried.

However, the third person who died, the retired athlete who died at home, had obvious signs of lock-picking.

"That 'keeper' has started to attack acquaintances?"

"Or, the goal was this acquaintance at the beginning!"

"The previous deceased was just to cover up himself?"

"Or, just a poor disguise?"

Qin Ran thought with his left hand on his chin, and suddenly a bold guess appeared in his heart.

Such bold speculation undoubtedly requires sufficient evidence to support it.

However, Qin Ran has a simpler way to tell whether his guess is right or wrong.

Qin Ran, who turned on the [tracking] field of vision, was looking for footprints inside and outside the room.

There are various footprints on the ground.

But most of them are from someone on the scene, and Qin Ran can clearly find the belongings of the footprints based on their footprints.

There is only one pair of footprints.

Who has been to the scene but disappeared?

murderer!

Moreover, these pair of footprints have obviously been here more than once.

Under the perspective of [Tracing], the brightness and dimness of footprints indicate the difference in the time of occurrence.

The bright traces, just a few hours ago, stayed in front of the dead body.

The dim traces were from a few days ago.

After comparing the pair of footprints, Qin Ran turned to look at Shi Qi.

"Give me a pen and a piece of paper!"

He said.

"Do what he said!"

Schi ordered to the policeman beside him.

After taking the paper and pen, Qin Ran began to quickly draw the footprints according to the size of his footprints he saw.

In three minutes, a pair of footprints appeared on the paper.

The patterns on the soles of the shoe are clearly visible.

At this time, the policeman who had left before trotted into the house with a marked map.

"Thanks!"

Although he knew that it might be his fuss, Qin Ran still thanked him and took the map in the other party's hand and confirmed it seriously.

There is no rule at all.

This is true whether it is normal knowledge or mysterious knowledge.

Qin Ran folded the map and handed everything to Shi Qi with the footprints in his hand, and said slowly: "I found some clues to this case!"

"What?"

Shi Qi was stunned.

"Simply put, I think the previous four cases are just to cover up this case!"

"After that guy took you into a dead end, he covered himself up so that no one would doubt him!"

"Of course. It's also possible that this case is a sloppy imitator!"

"So, I can only say that what I found was the clue of this case, the other party was an acquaintance of the deceased, and there were his footprints here!"

"But you just need to find him to know what's going on! By the way, I'll remind you. If you are not an imitator, that guy should be quite strong and good at using short blades like daggers. It's best to be careful when you act!"

Qin Ran told the other party what he knew.

"Go to investigate the dead acquaintance who matches this pair of footprints!"

While looking forward to walking, Shi Qi ordered his men.

"yes!"

After answering in unison, the police at the scene took action quickly.

Apart from the few patrol officers and forensic doctors who were guarding the scene, only Qin Ran was left.

As for which landlord?

He was also temporarily taken away for review.

Start with footprints.

Qin Ran looked around and it was obvious that no one could send him back to No. 1, Hei Street.

Shrugged. Qin Ran walked out of the house.

...

It was an hour later when Qin Ran took a rental and returned to No. 1, Black Street.

After paying enough fares, Qin Ran pushed the door and got off.

After learning that he was about to enter the dungeon world [Psychic Partner], Qin Ran, who had experienced the same dungeon as the same world as [Island Prison], was ready.

Not only weapons and equipment, but also a lot of necessary living needs.

Thanks to the blessing of [Unqualified Detective], Qin Ran has enough attributeless gems.

Although the equipment cannot be embedded, the money used to exchange for the dungeon world is still enough.

Of course, the system does not provide such redemption.

You need to find your own way after entering the dungeon world.

Fortunately, Qin Ran has many jewelry stores in this city.

Welcome back!

On a white cardboard, the ghost housekeeper Felid wrote such a text.

"Thanks!"

Qin Ran smiled and nodded, then walked towards Nikailei's study.

He did not forget that Nikailei had opened up the entire collection of books to him before.

A collection of 'spirituals' is tempting enough for Qin Ran, who urgently needs to increase the level of [mysterious knowledge].

Perhaps, there is no skill book that can directly ‘get’ and ‘prompt’ skill levels.

But there must be similar related knowledge.

Based on Qin Ran's understanding of "skills", each skill has been accumulated to a considerable degree of knowledge in this field and achieved a qualitative change process.

Without being able to directly obtain the skill book, he relied on knowledge accumulation to complete the process of obtaining the "skills", which may be slow.

But it is his only choice now.

Qin Ran would not give up on this only choice.

In fact, if Shi Qi had not arrived suddenly, he would have already read what kind of collection of books there existed.

As for Fellid's inability to communicate with voice?

Qin Ran guessed that it was because the other party was a ghost.

But Qin Ran couldn't know what the specific reason was.

His [Mysterious Knowledge] level is too low.

This made Qin Ran more and more eager to read the "Psychic" collection.

After pushing open the door of the study, Qin Ran looked at the carpet that should be an alchemy product under his feet, and then looked at the bookshelf.

It’s not that Qin Ran doesn’t want to study this carpet that looks special at first glance.

But he knew what he needed most now.

It is a good idea to set a lofty goal to motivate yourself.

But what is more important is: move forward to that goal with a down-to-earth perspective, rather than fantasy!
