Rainbow Tower, midsummer.

The city above the clouds is bathed in a blazing sun, and despite the protection of the magic barrier, most of the heat has been transformed into the power to protect the city, but looking up at the dazzling sunlight still makes people feel a sense of heat from within.

At the Stein Institute, Robinson was sitting boredly in his chair, pulling his neckline at the air outlet of the thermostat circle, trying to get cooler.

"As long as you have peace of mind, you can feel cool."

Beside him, a bespectacled man Odyssey with a book in his hand was looking at Robinson with disdain for some indecent behavior.

"It's been so hot this year, I remember it wasn't that hot last year."

Robinson picked up the Rainbow Tower Daily on his desk as a fan and glanced at the weather forecast on it.

"Today's maximum temperature is 36 degrees, oh my God, last year I remember the maximum was 34 degrees? At that time, there was already a continent-wide drought, and it seems that this year's artificial rainfall work has been even harder. ”

"Some people think that continuous high temperatures are not normal, and perhaps the exhaust gases emitted by our factories pollute the environment."

Odyssey said lightly.

"If Ora is here at this time, he will definitely say something...... Alas, it's a pity ......"

Robinson sighed as he looked at the corner of the lab, where it had been cleared.

Their colleague and classmate Ola was eventually found dead in his home after a massive explosion that destroyed an area including his apartment in the heat, where Ora's body was found.

This matter is in the official caliber with the previous defection of the high-ranking mage Enrique. Levin was connected, and after the traces of magic remained, Euler did die at the hands of Levin, but why Levin killed Euler and why there was such an explosion, people can't know.

For Robinson and Odyssey, although Ora is a guy who likes to boast and show off, he is always his companion, and such a friend who gets along day and night disappears in an instant, and the impact on both of them is huge.

On the one hand, Robinson and Odyssey originally thought that the Rainbow Tower was the safest place in the world, and they were already a little lazy and neglected to take precautions on weekdays, but they didn't expect that in this area, a mid-level mage was blatantly killed, and even according to their teacher Ludwig. Stein's account of the defected High Mage Enrique. Levin also almost caused great damage to the Rainbow Tower.

On the one hand, it also inspired the two of them to study magic harder and strive to improve themselves, because only in this way can they effectively prevent similar things from happening.

Of course, there is a limit to hard work, and at this moment, in this sleepy afternoon, the two took the opportunity of afternoon tea time to start fishing.

"Ah, the teacher asked me to bring you snacks."

At the door of the laboratory, Wendy, who was wearing a long dress, walked in with a plate of black tea and snacks, and the back of her head was tied up with a light blue ribbon, which seemed to have a bit more mature charm.

"Thank you."

Robinson took the plate with one hand, placed it on the bench, picked up the teapot and poured black tea into both cups.

"Wendy, you're getting prettier."

His words made Wendy smile a little shyly, and the ring on Wendy's fingertips reflected the sunlight, showing a little starlight.

She worked with the High Mage Ludwig. Stein registered her marriage at the beginning of the new year and is now Mrs. Stein, but despite this, Wendy still serves the front desk work, serving tea and water to the mages in the institute, in her words, although her magic level is not high, as long as she can support your research work, it is enough.

"I really envy the teacher, I can marry such a beautiful wife, I really want to have a girlfriend!"

Robinson took a sip of black tea, the richness of the tea that deepened his envy.

"Speaking of which, many of my classmates are single, and I can organize a fellowship when I have time, and they also have a lot of respect for mid-level mages."

Wendy said that they have just graduated, and most of the students are still staying in the Rainbow Tower, hoping to find a job, of course, the competition in the Rainbow Tower is also extremely fierce, even in institutions of higher learning such as the Rainbow Tower High Academy, less than 10% of the graduates who can successfully stay in the Rainbow Tower for more than three years each year, and more are returning to their hometowns to get a job in the Magic Association in their hometown.

"Okay, okay, Wendy, you're so nice."

Robinson showed a hearty smile, he is a straightforward person, not secretive at all, although it is easy to offend people, but he is also very easy to communicate.

Odyssey didn't get involved in this kind of talk, he liked magic more than women, and he didn't understand how women could be more attractive than studying the elements and magic.

But the black tea is still delicious, Odyssey has to admit it.

Wendy said goodbye to the two of them, prepared a new afternoon tea, went to the third floor of the institute, pushed the door and walked into Ludwig. Stein's office.

"I got some afternoon tea, my dear."

Wendy now became more like a virtuous wife, and her arrival caused Stein to raise his head slightly.

"Thank you, you can rest for a while, I'll finish reading this paper."

Stein's brow furrowed slightly, but when he lowered his head to continue reading, his face became more gloomy.

Wendy sat on the sidelines, put her hands on her knees and waited for a while, and when she saw that Stein did not move, she stood up and came to his side.

"Is there something going on at work?"

She could see that Stein seemed worried, but she didn't know why, so she could only ask.

"Hmmm......"

Stein put down the paper in his hand and nodded slightly.

"This is Reiner. Ian Gray's latest paper is also his first since last year's High Council. ”

Stein had many notes on the parchment in his hand, which he had apparently read many times.

"Ah......h

Wendy was a little panicked, she hurriedly touched Stein's forehead, and was a little relieved to confirm that there was nothing abnormal. Ian Gray's thesis was not even spared by the high-ranking mages, and she was afraid that something would happen to Stein because of it.

"I'm fine, don't worry, it's better to say that his paper coincides with some of the ideas I mentioned earlier. Ian Gray thinks more deeply and long-term than I do. ”

With that, Stein turned his head and looked at Wendy.

"Wendy, do you believe that the length of time will change?"
