Qian Bing's pupils shrank, and he immediately withdrew all his energy and entered a state of preparation for war.

Sure enough, the next second, Yu Xiaogang was ready to pull Qian Bing's braid in a meaningful tone.

"Student Qian Bing, do you have any questions about my class today?"

Qian Bing didn't know what he meant. He replied obediently:

"Teacher, I keep all the knowledge you mentioned in my heart!"

"Yeah?"

Hearing Qian Bing's answer, Yu Xiaogang's eyes showed a hint of playfulness and said:

"Then I'll give you a small exam in class. What is the maximum age for a soul master to absorb the first soul ring?"

When Qian Bing heard this test question, he sneered in his heart.

Do you have any other materials to take the exam? These are the things you can do when you come and go.

He complained in his heart, but he answered well:

"Theoretically, the limit period for soul masters to absorb the first soul ring is about 400 years, and if you want to infer that the specific time is 423 years.

However, I don't think this time has substantial significance, at most it can only be used as a reference.

Because the specific years for a soul master to absorb soul rings is affected by his own physique. For ordinary soul masters, not to mention 400 years, even if they absorb soul rings that have been over 300 years, there are considerable risks.

For those who have practiced special skills since childhood and have made great progress in their physical fitness, or for those who have special talents in physical fitness, it is much more likely to absorb the soul ring for more than 400 years.

Even for those evil geniuses, 423 years may not be their limit.”

Qian Bing stood up and answered without any fright, and spoke in a while. When he finished his answer, he realized that Yu Xiaogang, who was standing in front of him, had wide eyes and his face full of disbelief.

Could it be that I said something wrong?

Or did I say something I shouldn't say?

Since Qian Bing had been distracting his mind to practice Xuantian Gong before, he was not very clear about the content of Yu Xiaogang's subsequent lectures.

Seeing Yu Xiaogang ask him this question, he thought he had just told the whole class the maximum period that the first soul ring could absorb in class.

Yu Xiaogang has always believed that the limit collection period for soul rings of all levels is his own unique research result, and of course it is impossible to announce it easily.

Suddenly, when Qian Bing heard data exactly the same as his research results, he was naturally shocked for a while.

He quickly searched for memory fragments in his mind, searching for all the intersections between Qian Bing and himself, or the possible intersections. Finally, he thought that the two had a brief contact only when they registered for the freshman.

"My theory was not spread and promoted at Notting College, and it is logically impossible to be known."

Yu Xiaogang was thinking about it and was about to say something, but the bell rang just now, interrupting his thoughts.

He turned his head and looked at so many students staring at him, and simply swallowed the words to his mouth, gave Qian Bing a wink, and said:

"After class, come with me, I want to have some questions in-depth exchange with you."

Then, Yu Xiaogang announced loudly:

“Second.”

Qian Bing didn't know the answer he said, so he was shocked by Yu Xiaogang. He thought he was going to teach him a lesson alone, so he gave Tang San a helpless look and signaled him to go back to the dormitory first, and then followed Yu Xiaogang out of the classroom.

Yu Xiaogang didn't say anything along the way, and silently took Qian Bing through the teaching building to his separate room in the dormitory building.

After entering the door, he asked Qian Bing to sit down on the chair, while he sat casually on the bed opposite and said lightly:

"If I remember correctly, you are Qian Bing from Taolin Village. He has a natural soul power. I will take you to report it myself when I entered school."

Qian Bing nodded and said gratefully:

"Yes, teacher, I'm Qian Bing. I've always wanted to thank you but couldn't find a chance."

Yu Xiaogang didn't care about Qian Bing's attitude and asked again:

"Have you been to Notting City before?"

What does this question mean?

Didn’t he come to scold me? Why did he start investigating his household registration? Did Douluo Dalu also file a complaint for home visits?

Qian Bing showed a hint of doubt on his face, and he shook his head and said:

"No, this is my first time leaving the village."

A trace of sharpness flashed in Yu Xiaogang's eyes, and he finally asked what he really cares about.

"Then how could you know so much knowledge of the soul master, even the limit time of the first soul ring absorption?"

Well……

With Qian Bing's alertness, he immediately realized that he attracted his attention because he revealed the specific years of the soul absorption ring.

He reacted very quickly. After thinking through the key information, he showed a puzzled expression on his face and replied in a daze:

"Teacher, isn't this the ordinary soul master knowledge that everyone knows? I have known it since I was a child!"

After hearing Qian Bing's answer, Yu Xiaogang's heart trembled and felt uncomfortable as if his heart was being knocked.

Is this ordinary soul master knowledge?

Whose soul master theory is so ordinary? It is comparable to my decades of research!

A little brat is a little brat, and there is too much misunderstanding about the word "ordinary"!

However, Yu Xiaogang did not express his emotions in front of Qian Bing and explained:

"Child, this is not ordinary knowledge. It is a theoretical achievement that I have spent a lot of time and cost to research."

"Ah, so good?"

Qian Bing immediately exclaimed, his eyes wide open, his mouth wide open, his eyes full of disbelief, and his expression vividly showed his "uninformed suspicion".

"Note, teacher, the notes left by my parents speculate that the first soul ring absorbs the age of 423, the second soul ring absorbs the age of 764, the third soul ring absorbs the age of 1760, the fourth soul ring absorbs the age of 5,000, the fifth soul ring absorbs the age of 12,000, the sixth soul ring absorbs the age of 20,000, the seventh soul ring absorbs the age of 30,000 to 50,000, the eighth soul ring absorbs the age of more than 50,000, and the ninth soul ring absorbs the age of more than 100,000 years. It is clearly written."

Qian Bing's mouth completely shocked Yu Xiaogang, revealing the incredible feeling that he was as good as Qian Bing. The two of them looked at me and I saw you kicking each other.

After a while, Qian Bing asked softly:

"teacher?"

"Ahem..."

Yu Xiaogang came to his senses, secretly observed Qian Bing's expression, and made a secret judgment in his heart:

"From the performance of this child, it doesn't seem like he is lying. And I have never published any guesses about the absorption years of the next few soul rings. Is there really someone in the world who has developed the same theoretical achievements as me? Is this unlikely?"

Yu Xiaogang asked with a question in his heart and unwilling to give up:

"Child, can you tell me who your parents are?"
