The sky was a little overcast, and a breeze was blowing on the shore of Yeyin Lake. The siblings talked about the weird old professor again. Speaking of the old professor, they couldn't help but think of the mark on his forehead and the oath in the name of love.

They thought about it for a long time, and decided to go to the old professor themselves.

Inside Li Yun's office.

"Do you want to find an old professor?" Li Yun looked at the two children in surprise, "He is an old man in our academy, and even the dean has to call him a senior." Why are you looking for him?"

Bai Di said sincerely: "I heard that the old professor's magic is very powerful, and we want to apprentice." ”

"Apprentice?" Li Yun raised his eyebrows and said, "The old professor's apprentice is not so easy to be. And he won't necessarily take you. ”

Bai Ling said: "Teacher Li Yun, just tell us where the old professor lives, and we will visit him ourselves." ”

Bai Di also nodded. Li Yun was helpless, so he told them that he didn't know where the old professor lived, but there was an office in the college that the dean had reserved for the old professor, and they could go there and wait for him, but he didn't have much time to stay there.

The brother and sister said goodbye to Li Yun and walked to the old professor's office. Although Li Yun is their teacher, all he learns in the first grade is the knowledge from books, and Li Yun himself does not understand the true abilities of these children. Magic practice classes don't start until the second year.

The old professor's office is on the top floor of the faculty office building. Bai Ling and Bai Di climbed up to the top floor and saw a bronze lock hanging on the only wooden door.

People are not there.

"Go back or keep waiting?" Bai Ling asked.

Bai Di shook his head and grabbed the lock with his hand, red elements appearing in his hand and around the lock. The bronze lock melted directly, and the crimson liquid fell to the ground.

"Go in and wait for him. Bai Di said, pushing open the wooden door, "By the way, take a look." ”

The old professor's office was very clean, and the layout was similar to Li Yun's office, there was nothing special, not even the wardrobe and bed, and it was obviously not a place to sleep. Bai Dila sat down on a wooden chair, closed his eyes, and began to cultivate.

The only difference between the old professor's office and other places is that there is a skylight on the top floor. Bai Ling saw that his brother was cultivating, so he climbed out of the skylight by himself. It was the highest place she'd ever climbed.

You can see every part of the college, including the lake in the back mountain. Bai Ling felt that she liked this lofty feeling very much, so she sat down and cultivated.

......

Time passed slowly, and the brother and sister didn't eat dinner, and instead practiced it. It wasn't until late at night, when they were about to go back to their dormitory, that they suddenly heard a voice coming from outside.

"Huh, why is my lock broken again?, and what little bunny came up to do the bad thing?" a slightly older voice.

It's the old professor who is back. Bai Ling and Bai Di hurriedly leaned aside, waiting for him to come in.

The old professor was still dressed in a gray robe, and his gray beard never seemed to be shaved. But unlike the bombastic old professor that the brothers and sisters had seen in their dreams, he was walking a little unsteady at this time, and he still exuded a smell of alcohol.

The brother and sister looked at the old professor who walked in in shock, staggering, and didn't even notice them. I can't help but regret a little, should I really believe in a dream?

The old professor staggered into his office. He drank quite a bit tonight, in fact, he went to drink some every night. Every time he went to the bar near the academy to drink the worst wine, and only occasionally when he was in a good mood would he buy slightly more expensive wine.

Although he went to a bar, he never drank alcohol, not girls. Of course, it has nothing to do with your physical state. It's just that, in his eyes, the bewitching woman in the bar twisted her ass, which made him have no beautiful imagination at all, so how could he think of going to the bubble? So, he became an old bachelor for the rest of his life.

What's wrong with the old bachelor, he hasn't met a girl who makes him tempted. The old professor snorted and pouted unhappily. The expression is like that of a child.

At this moment, he suddenly felt two guys in front of him, looking at him with amazement.

"Ahh

"Ahh

The screams rang out at the same time, and the old professor's drunkenness was half awake at once. When I looked closely, it turned out that two children were standing in front of me, as if they were still wearing the uniforms of the Persian Junior School of Magic.

"What are you doing here?" asked the old professor solemnly. Just now, when my ugly state was seen, I was in a bad mood, and the consequences would be very serious.

"First time we met, old professor, I am Bai Di, and this is my sister Bai Ling. Bai Di replied, "We are here to ask you to answer your own troubles. Like, a dream. ”

When the old professor heard this, his anger suddenly went down by more than half. smiled slightly: "It turned out to be you." Didn't I say I would come to you? and it wasn't a dream, it was something that actually happened in my space. ”

The brother and sister looked at the old professor in surprise, a little speechless. Space ability, that shouldn't be the ability that this world has, right? What is the identity of the old professor?

"As you might guess, I'm not from this world. But I can't tell you, that's the rule. The old professor said.

"But we're willing to apprentice. The brother and sister replied in unison, as if they had known that the old professor would say this.

The old professor was stunned for a moment, shook his head slightly, and nodded again. smiled: "Yes, I'll take it." ”

Bai Di and Bai Ling glanced at each other, both saw the excitement in each other's eyes, and then knelt down together, ready to kowtow.

"I can't do it. The old professor put his hands on his hands, took the bodies of the two children up, and explained, "After making that vow, we are equal." You can't kowtow to me, that's the same rule. ”

"If you don't kowtow, you can also be considered an apprentice?" the brother and sister asked suspiciously.

"Why not, I never take in apprentices easily, let alone be as dogmatic as other teachers. The old professor said lightly, "Okay, children, since you have recognized me as a master, you must never abandon each other for the rest of your life." So, I'll give you a welcome gift, come with me. ”

As he spoke, the old professor waved his hand, and an eight-foot-long white scepter appeared in his hand. The crystal ball at the top of the scepter emitted a dazzling rainbow of light, and the old professor held the scepter up, and a purple light sprayed into the skylight on the top floor.

The moment the purple light touched the skylight, the entire skylight collapsed, and the back of the skylight was no longer night, as if it was connected to another space.

"Go up, kids, and welcome to visit my home. The old professor smiled slightly.
