A familiar and cheerful girlish voice came from outside the door, and Thor's eyes widened in surprise.

He removed the devil vine in front of the door and released his spiritual power.

There was indeed a man and a woman standing outside the door, and they did not resist Thul's mental scanning.

After this exploration, Thor immediately opened the gates of Blackcastle.

Klee, who still had a metallic reflection on her face, stood in the doorway expressionlessly.

The other, frowning, seemed to be wondering what "old couple" meant.

"Klee!"

"Byron, senior!"

Thor didn't expect to see both of them outside the tower at the same time.

"How did you all end up here at the same time?" Thor looked at Byron first, "Could it be that the senior came over to take over the Black Castle?" ”

"It's me, it's me!" Klee raised her hand and shook it in front of Thor, "Senior Byron just happened to be looking for you again, so he came all the way with me." ”

"Hmm." Byron didn't open his mouth, just nodded in agreement.

Savor was a little surprised, and he got out of the way and let two friends who had traveled long distances come in to rest.

The three of them walked together in the Black Castle, and Thor asked Klee, "Aren't you only in the second level, how can you take over the Black Castle?" ”

"Aren't you also level two?" Klee rolled her eyes, but she was only habitually complaining, "I won't run around when I come to Blackcastle, just do some study and experiments here, and help pass the news between the Principality of Kema and the Wizard Tower by the way." ”

Thor paused, his brow furrowed, and made his concern clear, "It's not safe in Blackcastle. It's better to have a Level 3 apprentice in charge. ”

Kree frowned and stopped, "I know, so I don't usually leave Blackcastle except to deliver news." And the mentor gave me a powerful witchcraft prop. If anyone really wants to invade Blackcastle, this thing can protect me until the Wizard Tower comes to my rescue. ”

"And there's a reason why I applied for this job on purpose......"

Senior, who was silently walking at the back, didn't know what he was thinking. Thor and Klee were still walking forward when they stopped, and then slammed into Thor's shoulder.

This directly interrupted Thor's conversation with Klee.

Because when Thor came into contact with Byron's body, there was a sudden ripple in his gray-white skin.

Although he was obscured by his clothes, Thor could feel as if his skin had cracked a small opening.

The tear didn't hurt, and it seemed like something was moving inside the wound.

Solmer silently smoothed the skin and allowed the wound to heal on its own, then looked at Byron with a blank expression.

All of this happened in a short period of time, as short as a flash of thought.

Klee only realized what was going on at this time, and she also turned around, "Instead of worrying about whether I can live well in Black Castle, you should ask Senior Byron about the situation first." I think he's in a bit of a hurry. ”

Thor looked at Senior Byron seriously this time, and Byron stood there and let Thor observe him.

"Senior...... Was it the last question? ”

Byron hesitated and nodded, but still didn't "open his mouth".

Saul realized that after meeting Senior Byron this time, the mouth on his neck had never cracked, and he had always used body language or a dull "uh-huh" instead.

Is the problem so serious that you can't even open your mouth to speak?

Thor immediately said to Byron, "Senior, you can wait for me in the laboratory on the third floor." I'll go over to you as soon as Klee and I hand it over. ”

Byron nodded.

In the past few years, he has often been in and out of the Weeping Hand Valley, which is close to Mobei City, so he is still familiar with Black Castle Bisol.

The three of them split up the stairs in the antechamber, one going up and two going down.

Thor walked along the basement, the cellar, and the cave to see the giant taproot veins of the Devil's Vine.

"This is the Devil Vine, I was in a hurry to take up my post, and I only knew that by injecting spiritual power into the taproot veins of the Devil Vine, I could become a temporary master. But you took the assignment and should know more than I do. ”

"Of course." Kree nodded proudly, and she rolled up her sleeves, revealing two white arms that had not seen the sun all year round.

Her skin was fine, and there was a surging golden glitter on it, like a girl sprinkling a layer of gold dust with makeup.

Thor stared at Klee's arm.

"Is it pretty?"

"Haven't you had a metal toxin on your body yet?"

"I left it on purpose." Kerry said, pulling out a tube of blue potion from her coat pocket, "It's for my next research." ”

She opened the potion and swallowed it all with her head up. Then she immediately lowered her head and covered her mouth, tears welling up in her eyes, like swallowing a tube of mustard.

After a few seconds of waiting, she blinked the fog from her eyes and hissed to Thor, "The radioactivity of the metal you mentioned last time gave me a little inspiration. I decided to try to develop this particular metal toxin. However, this toxin can easily get uncontrolled and affect the people around me, so my supervisor suggested that I find a closed and uninhabited space and continue my research, and if I have any problems in the middle, I can contact him directly. ”

"So you thought of Castle Black?" Thor sighed, "Do you know how to contact the Wizard's Tower in Castle Black? ”

"Of course, I came here with a lot of preparation." Klee smirked at Thor and raised her eyebrows, "Only those who have officially become the owner of Castle Blacks can contact the Wizard Tower, and the temporary master cannot." So don't worry, I won't be in danger but unable to call for help. ”

"I see." Thor was stunned.

So Brie and the others were sure that there was no way for them to ask the Wizard Tower for help.

Kree let out a long breath, raised her hands, and approached the devil vine in a posture as if she was going to strangle someone.

[Hello, it seems that you are my new master in the future. 】

The Devil's Vine's voice sounded a little excited.

But Klee didn't respond to it, and continued to slowly approach the Devil's Vine.

"You seem to be a little nervous." Thor was a little confused.

Kree didn't need to be reminded by him, she obviously knew the process of becoming the master of Castle Black, but she seemed much more solemn than Thor was at the time.

Klee stared at the Devil Vine, "Don't talk to me yet." I heard from my mentor that it was very difficult to establish a spiritual connection with the Devil's Vine, which prepared me for the fact that I might not be able to succeed at the first time...... I don't want to drink a second dose of potions. ”

She told Thor to keep his mouth shut, but she was there to talk.

Thor couldn't help but smile, "I'm really nervous. However, is it so difficult to establish a spiritual connection with the devil's vine? ”

Thor squinted at the Devil Vine.

【……】

A few tiny air roots twitched twice for no apparent reason.

At this moment, Klee finally walked up to the devil's vine and pinched it with both hands, leaving a crescent moon on the surface of the rhizome with her neatly trimmed nails.

The muscles on Klee's face tensed, and it was clear that her brain and body were working together.

After another minute, she suddenly opened her eyes, her mouth slightly open and a look of surprise.

"I succeeded?" She pursed her lips, "It's not that difficult!" ”

She suddenly looked at Thor, "Did you do something?" ”

Thor spread his hands innocently, "You have established a connection with the Devil Vine, what can I do?" ”

Klee narrowed her eyes, "Hmph, when you say that, it's even more unbelievable!" ”
