Riding in a horse-drawn carriage, Ferrin arrives at Cleveland Hospital, the hospital run by the Secret Medicine Society, where the Constant stronghold is located.

He had come here to borrow the bell of yesterday.

The creator of the humanoid mist monster cannot be traced by scent and traces, so only breath tracking and past imagery are left.

The humanoid mist monster has been destroyed, and it is no longer possible to search for the remnants of the creator on the humanoid monster, so it can only be searched with the help of past images.

Thinking of searching with the help of past images, he naturally thought of the cursed object of the Secret Medicine Society, the Yesterday's Bell, so he came to the Secret Medicine Society.

After arriving on the top floor of Cleveland Hospital and revealing his identity, Ferrin was received.

In the parlor where the potted plants in the room were medicinal herbs that he had visited more than half a year ago, Felin met Christine Otto, the head of the Secret Medicine Society in Conston City.

She was wearing a white coat, her brown hair was coiled, and she had an elegant temperament.

In addition to her, there was also a young woman who was also wearing a white coat with beautiful facial features and beautiful blue eyes. Mechel.

"Director Sox, what's the matter with your visit?"

Christine looked at Ferrin, who was sitting opposite her, and couldn't help but sigh in her heart.

When I met the other party more than half a year ago, the other party was just a newcomer who had just become a mystician, although he showed a good talent, but after all, talent is only talent and not strength.

But I don't want to think that in just over half a year, the other party already has a strength far above him, and has become the deputy director of the Security Bureau, and he has been assessed as having the potential to become extraordinary, and his reputation is mysterious.

"Lady Otto, I have come this time to borrow from you the cursed object of the Secret Medicine Society, the Bell of Yesterday."

Fei Lin explained what he meant.

"No problem, Helen, go and fetch the clock of yesterday."

The Secret Medicine Society and the Security Bureau are cooperative, and it is naturally impossible for Christine not to agree, she instructed Helen next to her.

"Okay, teacher."

Helen left the living room for another room, and soon after, she returned with a half-foot-wide and one-foot-long clock in her hands.

The casing of the clock, made of brass, already has a slight patina on the surface, which is the same yesterday's clock that Ferrin once used.

Helen came to Felin's side with yesterday's bell and placed it on the coffee table next to Felin, who nodded to her and smiled.

"Thank you."

"No, you don't."

Helen smiled and shook her head, happily sitting back in her seat.

After lingering for a while, Felin took his leave, and in the carriage, he went straight to the street where the humanoid mist monster was killed.

The use of yesterday's bell will cause some movement, so in order to avoid causing a commotion, it is best to use it at night.

For this reason, he had gone to borrow the clock of yesterday when it was almost time to get off work, and now he had finished work, only an hour or two before it got dark.

After dining at a nearby restaurant, it was almost dark, and he came to the place where the humanoid mist monster had been killed, crossed the cordon, and entered the house.

Houses that have just died look a little permeable in the evening, where few pedestrians can be seen.

Occasionally, pedestrians pass by, and they will walk briskly, obviously avoiding this place.

However, Fei Lin did not have the emotion of being afraid, even if he had killed all the real ghosts, he naturally would not be afraid of the rooms that had only died.

He sat down on a stool in the middle of the room and waited for darkness to come.

I didn't have to wait long, it was completely dark, and there were no pedestrians on the street.

Felin stood up and picked up the Yesterday's Clock that had been placed beside him.

When you flip the knob of yesterday's clock in reverse, the hands of yesterday's clock begin to recede backwards, and the room changes.

It had just fallen at night, but the room was slowly getting brighter, and soon it seemed like daylight.

This is the extraordinary ability of yesterday's bell to activate, and the images of the past are recreated.

Rewind time to the time when Ivy and Essie encounter the humanoid mist monster, and images of Ivy and Essie's past appear in the house.

Felin looked for the humanoid mist monster, and then, with surprise on his face.

"No?!"

Although there are images of Ivy and Ash in the room, there is no image of a humanoid mist monster.

It's not that the time is wrong, it is not difficult to judge from the standing posture of Ivy and Ash that the two have encountered humanoid fog monsters, but there is no image of humanoid fog monsters in the room.

"Yesterday's bell was disturbed by some force."

Ferrin's brow furrowed.

The reason why the humanoid mist monster cannot be seen is probably because the past images of the humanoid mist monster are disturbed by some kind of force and cannot be revealed.

"Being able to interfere with past images, it seems that the maker of the humanoid mist monster is not ordinary."

Felin fell into thought.

He originally thought that the humanoid mist monster should be at the Central level, but now it seems that it is not just the Central level.

If it was only the Central level, it would never be possible to interfere with the Type 2 curse of Yesterday's Bell.

"Type 3 Yesterday's Bell may be discovered, with my current mystery point is enough to raise Yesterday's Bell to Type 3, do you want to upgrade Yesterday's Bell to Type 3?"

After a moment of consideration, Ferrin decisively chose to upgrade the Yesterday's Bell to Type 3.

Now he can not only improve extraordinary items, but also downgrade extraordinary items, and he doesn't have to worry about returning it, the Secret Medicine Society will find out that the Yesterday's Bell is abnormal.

Swish!

Stopping the Yesterday's Bell from activating, Ferrin puts the Yesterday's Clock into the panel and chooses to upgrade the Yesterday's Clock.

The mystery point is reduced by 195, and the word "Type 2" on the Yesterday's Clock begins to flash.

With this flickering, a strong mystical power fluctuated, and a mystical force was invisibly attracted and came this way.

Enter the panel, and then pour into the Yesterday's Bell to improve the grade of Yesterday's Clock.

After a few moments, the mystical power ceased to infuse, and the word "Type 2" of the Yesterday's Bell disappeared into the word "Type 3", indicating that the Yesterday's Bell had reached Type 3.

"Make sure I can afford the side effects."

Ferrin removed yesterday's clock from the panel and used the Eye of Identification to check for changes.
