Socially anxious people transmigrate to another world; living in seclusion is too difficult.

After the brief commotion, the students in the lecture hall gradually quieted down, patiently waiting for their teacher's arrival. Zhou Changning, who had come outside, quickly caught up with Jiang Jishi. He stepped forward, grabbed Jiang Jishi, and asked mysteriously, "Guess why Lord Qin suddenly wanted to come to your academy?"

Jiang Jishi asked, puzzled, "Why?"

"Come, come, let's go to your study first. I'll tell you, but you'll have to bring out some more of that tea from last time."

Jiang Jishi glanced at him, and finally said helplessly, "Alright, let's go, Dean Zhou."

Su Yang remained seated, waiting. At that moment, a woman entered the lecture hall, instantly attracting the students' attention for a moment. However, seeing that it wasn't their teacher, everyone went back to chatting. The woman then walked straight to Su Yang and sat down next to him. Since she was the only empty seat in the entire lecture hall, Su Yang didn't think much of it and paid little attention.

This woman was Qin Xiyun, who had changed her appearance through disguise. After knowing that everything was ready, she came into the lecture hall and sat next to Su Yang. Her purpose today was to observe Su Yang closely to find out his specific strength and how he had evaded her elemental detection.

Before long, the master finally arrived late. After entering, he didn't offer any explanation, but stood on the stage, opened his book, and began to explain at length, much like some of the teachers in the original world.

Su Yang listened very attentively, not missing a single point of knowledge. It must be said that although the master's tone was calm and without much fluctuation, his explanation of the knowledge points was very detailed. Starting from the elemental particles, to the formation of the elemental fusion particles, how to constitute elemental power, and how to combine with spiritual power to exert stronger power, he analyzed every point carefully.

From his master's explanation, Su Yang learned that after entering the continent, he heard that the fourth and fifth ranks could be further subdivided. Generally speaking, the world divided elementalists into seven ranks, and each rank was further subdivided into seven levels.

For example, a newborn baby, barring unforeseen circumstances, will be at the first level of elemental power. As the baby grows older, if it is not suitable for cultivating elemental power, the baby's level will remain at the seventh level of the first level, and will not be able to improve further, but will still be able to use simple elemental power.

Those suitable for cultivation generally participate in tests at various academies, known as the Transcendent Test. Passing the test signifies reaching the second rank, having transcended the mortal realm. The basis for distinguishing different stages and levels is the strength of the elemental spirit. To increase strength, there is no other way besides growing older and training one's mental strength. The most commonly used methods are adventure and meditation. Therefore, to a certain extent, talent determines the starting point, while effort determines the upper limit.

However, in Su Yang's view, this world has not yet come into contact with the science of the original world, and has not yet seen through the essence of the world. No wonder his elemental power has increased so rapidly after he came to this world.

Qin Xiyun sat to the side, secretly observing and testing Su Yang, trying to figure out his strength. However, after several attempts, Su Yang did not react. Instead, he focused on writing something on the paper. This made Qin Xiyun curious, and she adjusted her distance several times, trying to see what Su Yang was writing on the paper.

On the paper in front of Su Yang were the most basic knowledge points of elemental power written crookedly. Because he was using a brush, Su Yang's handwriting was really mediocre, and probably only he himself could understand it. This made Qin Xiyun, who was trying to see it clearly, keep getting closer and closer. However, because she was too focused, she got closer and closer to Su Yang, almost touching him.

When she came to her senses, she found Su Yang looking at her with a strange expression. Realizing her lapse in composure, Qin Xiyun quickly moved away, pretending nothing had happened. Seeing her leave, Su Yang, though feeling odd, didn't say anything and continued to concentrate on the lesson.

"Oh dear, how did I get so close to him without realizing it? How embarrassing. Wait a minute..." Qin Xiyun realized something: "I was able to get so close to him just now without being affected, does that mean there's no elemental barrier around him? Could it be that he detected my elemental detection yesterday and specifically created a barrier for that purpose?"

Thinking this, Qin Xiyun used elemental detection again, releasing an invisible wave, but it was still blocked in front of Su Yang. So she changed her approach, moving her chair closer to Su Yang while releasing detection, until she entered within one meter of Su Yang's body, at which point her detection wave reacted.

Seeing her success, Qin Xiyun was as happy as a child, unable to hide the joy on her face: "So it really was a barrier. It seems he really is a high-level elementalist. But why does he keep the barrier open during non-combat periods? Isn't that just a waste of his mental energy and elemental power reserves?"

Another question arose immediately. Qin Xiyun hadn't expected that Su Yang maintained the existence of the Flowing Cloud Barrier around the clock. The elemental power consumed couldn't keep up with the speed of recovery. In her opinion, a barrier made of pure elemental power was far stronger than those generated by other elements, such as earthen walls and water networks.

The ability to use an elemental barrier is an important criterion for judging whether an elementalist has reached a high level. The cost of an elemental barrier is undoubtedly huge, which is the main reason why Qin Xiyun was surprised, because she did not see any signs of fatigue on Su Yang's face.

At the same time, Su Yang noticed that the woman sitting next to him had started moving her chair closer to him again, and then suddenly stopped and started laughing foolishly. Su Yang thought to himself that she was not mentally normal. Could it be that she had gone crazy from exercising her mental strength?

Qin Xiyun quickly discovered a problem: "Why couldn't I detect him before, but I could after getting close enough? Was he deliberately maintaining a safe distance to give himself time to react? And when was this barrier released? Could it be that he already sensed my detection when I released it?"

To verify her idea, Qin Xiyun moved further away and released the probe again. Sure enough, the probe was blocked. She then moved closer to the original position and released the probe again, and it was successfully released. She repeated this process until she was exhausted, but Su Yang's barrier was still there. This discovery made her somewhat insecure.

"Is his elemental reserve really that deep? It's been so long, why is the barrier still there?" Qin Xiyun slumped helplessly on the table, still unable to figure out the question.

However, her unusual behavior was noticed not only by Su Yang, but also by the master on the stage. A shout came from above: "Student, why are you moving your seat repeatedly!"
