Tingen Nord, Wendelstraße 26.

Grandin, dressed in black, took advantage of the fact that there was no one around, quickly removed the cordon that blocked the road, opened the door of the room blackened by the fire with a wire and some simple techniques, and walked into the room.

Because of the 'gas explosion' a few days ago, there was another group of police patrolling the streets of Wendell Street after nightfall. And some of the surrounding residents have increased their own guards and hired a lot of security personnel.

Of course, Grandin could have come here to investigate in a big way in his inspector's uniform, but for reasons that he didn't even know himself, he didn't want too many people to see him.

"Click."

As the cylinder snapped back, the door was closed again. After making sure the door was locked, Grandin turned his head and began to observe the room.

Because the broken windows had not been blocked, the smell of smoke in the house had dissipated. Taking advantage of the not-so-bright moonlight outside the window, he took out the 'tracking potion' from his coat pocket, and with a few shakes, the green fluorescence spread out in the space.

The room has been cleaned, and the items that survived the various fires have been taken away after several inquests and inspections by the night watchman and the National Police Agency.

Now there is only a scorched black background in the empty room, and now the house will be sold again when the police department closes the case.

This is also what makes him most puzzled, if he left something behind, it should have been discovered after many searches by the night watchman and the police, right?

With questions in mind, Grandin stepped through the hallway, past the living room, and finally into the once-luxurious bedroom.

The words 'There is hope' still on the wall, and it can be seen that the investigators did not pay much attention to these handwritings, probably thinking that it was some kind of prank, so they still left them as they were, and did not do anything about it.

The handwriting is a dragon and snake, and it has his usual writing characteristics.

Grandin followed the strokes and tipped his fingers on the wall again, then sighed and said to himself without making a sound:

"Depending on my personality, there is a real possibility that I will leave something ......"

"The night watchman and the police can't find it, which means that a special method is needed."

He tried to let his spiritual spread cover the handwriting on the walls, but it was in vain and didn't make any difference.

"Hey, it's too easy to discover the secret if you infuse the spirit, and I'm sure I'll make sure that only I can activate it in the future...... Maybe it's hometown? ”

Grandin coughed, and continued to try in Chinese:

"Open the sesame door."

"Alajo Cave Open."

Grandin Ode...... Golan. ”

The last name evoked memories and made it difficult for him to speak, but the handwriting on the walls was unresponsive.

"Maybe my guess is wrong, this is an ordinary brick wall. Klein also did a simple divination at the time, and confirmed that there were no secret rooms or secret compartments here......"

Grandin pondered for a while, and then suddenly spoke coldly:

"Fate!"

In the cold green light, the walls were still silent.

"Heh, this won't work, there's nothing here?"

"If anything...... It shouldn't be difficult for me to open it, and it needs to be unique, and only I can do it......"

Suddenly, Grandin thought of the weirdest and most special thing in himself, and as soon as he thought about it, the branches of the 'Numerology Tree' that others could not see poked out of his body.

The dry branches were traced along the handwriting under his manipulation, and when he finished writing, Grandin's heart jumped, and he vaguely seemed to grasp some kind of opportunity.

Following his vague intuition, Grandin pondered for a moment, and then his eyes widened, and the spirituality gathered and burned in his eyes, pure golden flames overflowed his eyes, and the dead branches of the 'Numerology Tree' retracted, and then a large tree phantom like a dead tree jumped out from behind him.

Its branches continue to grow verdant young leaves, which then decay and wither.

The crimson moonlight outside the window also shone on the wall through the shadows of the leaves, and this time Grandin did nothing, and the wall changed.

A little light rose from the middle of the handwriting, and then an invisible vortex absorbed the handwriting, moonlight, and brick walls, and the whole room was plunged into absolute darkness.

But in just a moment, a splendid river with no end in sight appeared in front of Grandin's eyes, and it flowed with a 'boom'.

The river stretched from his feet to the end of his sight.

He tentatively took a step forward, only to find that the soles of his feet were pinned in place, unable to move.

The brain wanted to swing his hands, but his body refused, and he couldn't even blink, he was forced to open his eyes wide, and sour tears soon filled his eyes.

These restrictions seemed to force him to use the only thing he wasn't constrained by.

So the branches of the 'Numerology Tree' poked forward and stretched out into the bright river. When it retracted, Grandin's body sank, and the tip of the branch actually brought back an object from the river!

Before he could take a closer look, there was an illusory sound of shattering, and all the visions of the long river and the dead trees disappeared with the sound. In front of him, there was still the same gray and black wall, and the 'tracking potion' in his hand was also emitting a glowing green light.

But something did happen.

"You can pass me the item, why don't you leave a word by the way? Oh, am I going to be a Riddler in the future? ”

Grandin grumbled and held up the 'Tracking Potion', relying on its light to carefully examine the items he had obtained.

I have to say that his curiosity has been completely aroused now. After all, this is a gift from the future self to the present body by traveling back to the past!

With the joy of successful decryption, he looked down, but the more he looked, the more stunned he became. The strange sense of familiarity turned over in his mind:

This is the lead box where I store the 'Flesh Badge'!

When he had this clear realization, the pocket in his chest suddenly emptied.

The seal box with his body temperature was gone, and the slightly cool back of the 'Flesh Badge' was directly attached to the lining of his waistcoat.

"Is this an experiment that I will do in the future, heh, without knowing if the experiment will be successful, I will indeed start with the cheapest and most ordinary things......"

Grandin habitually shook it twice, only to feel something inside hit the inside of the box.

"It's not a living thing, it's not a liquid, it's a soft material......," Grandin closed his eyes and carefully probed the lead box with his spiritual coating for a while before exhaling, "There is no danger." ”

What's in the box? For a moment, all kinds of possibilities flashed in his mind.

But in the end, he made up his mind, and only after throwing out his Hidden Blade and walking around the bedroom and laying out the spiritual wall did he solemnly hold the lead box in the palm of his hand and open the sliding cover.

The lid opened, and a drop of golden heart-shaped gem like a liquid and a crystal, and in the middle of it contained an illusory balance, appeared in front of his eyes!
