Mu You tried to get the character to push the door open.

[You want to push the door in, but unfortunately the door of the witch's house is sealed by a magic lock, and you can't open a single crack with all your strength. 】

"Sure enough, there's a magic lock!"

Mu You was not surprised by this, opened the panel, and clicked 'Lock Heart Hole Open'.

[You want to use the lockpicking spell to forcibly unlock the door of the witch's house, but due to the witch's extremely high spell level, the probability of successful unlocking is only 1 in 100,000, do you confirm the attempt?] 】

"Hiss, one in 100,000 ......"

The corners of Mu You's eyes twitched.

It is worthy of the lock set by the witch, and the high-level lock-picking spell has only a 1 in 100,000 probability of being lifted, which can be seen from here, how powerful this witch is!

"Confirm."

Mu You clicks OK. If someone else comes here, he will definitely give up directly, and the probability of 1 in 100,000 is no different from zero.

But he has a pocket watch, and he can still struggle.

[You used the lock picking spell, but unfortunately the door has not changed, and the lock has failed! 】

"Backtrack!"

[You used the lock picking spell, but unfortunately the door has not changed, and the lock has failed! 】

"Come again!"

[You used the lock picking spell, but unfortunately the door has not changed, and the lock has failed! 】

……

Next, Mu You began an infinite journey of backtracking and unlocking.

There is no consumption when you press the pocket watch, and after going back in time, the used mana will be restored, and even the time will always stay in this five-second range, so you don't need to worry about the passage of time and the problem of running out of mana.

Theoretically, probability things are meaningless in front of the surface of time, and no matter how low the probability number is, as long as it is not zero, it can be turned into 100% through an infinite number of attempts!

- Provided, of course, that he has enough patience and willpower.

Mu You soon discovered that he had somewhat underestimated the concept of one in the order of 100,000.

The time pocket watch can indeed go back to many things, but there is only one thing that cannot be returned, that is, his memory, under tens of thousands of repeated labor, the strength of the destruction of the spirit is unparalleled!

In the first few hundred times, or even thousands of times back, Mu You's brain can still operate relatively clearly.

But when the number of times increased rapidly, reaching tens of thousands, his consciousness gradually began to be chaotic, and in the infinite mechanical repetitive movements, the human brain easily entered a state of emptiness.

Mu You can't remember how many times he has gone back, tens of thousands of times? Hundreds of thousands of times? Anyway, he kept pressing the pocket watch, and then mechanically clicked 'OK' on his phone.

Two simple movements, repeated countless times, made his brain almost turn into a paste......

Just when Mu You opened the lock and was about to have a nervous breakdown, the picture that had always remained unchanged finally showed some slight changes for the first time.

[You used the lock picking spell, and the door suddenly popped open a crack, and the lock was unlocked! ] 】

"Hmm......"

Mu You's fingers had already stopped on the pocket watch button, and he was about to press it.

Fortunately, he reacted quickly enough to stop his movements in time, giving him a cold sweat.

After watching it several times and confirming that it was really successful, not his own hallucination, Mu You burst into tears, hundreds of thousands of attempts, it can be regarded as a success!

However, this thing is a success, but it is really disgusting, Mu You swears that in the future, unless necessary, he will never engage in this kind of mental pollution operation again!

After taking a few deep breaths and pouring a large glass of cold water, Mu You recovered, hurriedly returned to the game, and controlled the character into the house.

Now, even if the witch was sleeping at home and found someone intruding and angrily crushing him, he had to go in and take a turn, otherwise he would be really sorry for the mental destruction he had suffered!

[You push open the door and walk into the witch's house, only to find that the building is empty and lifeless. The floor and all the desktops were covered with a thick layer of dust, the walls were yellowed and blackened, the books on the rotten shelves were all in tatters gnawed by insects, and not a single book could be found, and the ceiling and all the corners were covered with thick cobwebs—all signs were that it had been uninhabited for a long time! 】

"Hmm......"

Mu You was stunned, how long has this witch been away from home?

It would take at least a few years to make the books on the shelves run out of bugs, right?

He thought that the witch would only go out once in a while, and would come back soon, and that he should come back to see if he didn't travel for a few months.

It turns out that this is not the case at all now.

After not returning home for several years, the witch either died outside or had made her home elsewhere......

"However, the game doesn't prompt the inheritance of the ownerless inheritance, so it shouldn't be dead yet, right?" Mu You thought about it, and then manipulated the character to 'search'.

[You searched the building and found five bottles of intact poison in the pharmacy!] 】

[Witch Poison: A highly poisonous potion specially developed by witches in order to deal with werewolves, the smell of the potion has a fatal attraction to werewolves, and the lifespan of the werewolf is -5 after taking it, and the lifespan of the werewolf is -10 after taking it. 】

"Poison!"

Looking at the latest prompts that popped up in the game, Mu You's eyes lit up.

I found the poison he needed the most at once, and it was still five bottles in a row, and I finally didn't let him come in vain!

Mu You hurriedly clicked 'Search' again, expecting to find some other treasures.

[You searched the building, but unfortunately all the items have rotted and deteriorated, and you can't find anything usable. 】

[Jack-o-lantern effect, trigger!] 】

[Under the reflection of the cyan glow of the jack-o'-lantern, you found some strange traces in the basement of the witch's house.] 】

[The corner of the basement that should have been empty, but under the illumination of the light, the outline of a transparent cloak was faintly revealed. 】

[You stepped forward and lifted the cloak to take a look, it turned out to be an invisibility cloak!] And under the cloak, there is also a well-preserved book! 】

[You have obtained a copy of the 'Cloak of Invisibility' and a copy of 'Anseni Vivien's Journal of Dark Arts Research.'] 】

"Oh?"

Originally, Mu You was hopeless when he saw the first sentence, but he didn't expect the pumpkin lantern, which had not moved for the past two days, suddenly gave him a big gift at this time!

Invisibility cloak, needless to say, everyone who understands the role understands.

As for the second piece......

"Anseny Vivien, that should be the witch's name...... However, the study of black arts? Doesn't black magic generally represent evil? Is this a black witch who studies dark magic? ”

Mu You's face was strange.

Of course, this is not a problem for him, it doesn't matter if it's black magic or white magic, as long as it can make him stronger, he won't refuse to come!

Mu You couldn't wait to click on the 'Research Log'.

A three-inch-thick hardcover bookcase appeared in his hand, and on the cover was the words 'Dark Arts Research Journal' engraved in the language of the stars.

"Such a thick book...... How much magic is there! ”

Mu You swallowed, feeling as if he had discovered the treasure of the dragon.

Taking a deep breath, he flipped open the lid of the bookcase with excitement.

Outcome......

Empty!

It's actually empty inside!!

Looking at the empty box, Mu You was dumbfounded for half a minute before he came back to his senses: "Shenma situation? ”

Bai made him excited, but it turned out to be an empty box, and he deliberately hid it with an invisibility cloak, specializing in people's mentality, right?

Mu You had the urge to burn the box on the spot.

Fortunately, after he picked up the box, he quickly noticed that at the bottom of the box, there was also a small character engraved with the spirit of the planet.

Hurriedly took the Star Spirit Dictionary and translated it.

Want to learn dark arts? Go find it! A hundred miles away from Anning Village, in the Black Forest, go straight north, and there is a small wooden house deep in the forest, where I buried everything! 】
