The final answer given by the Scepter is no more than 30%.

This made Shi Lei realize that Heika had developed his brain domain twice, five percent each time.

This time, five percent obviously has not started to be used yet and can be removed. The previous five percent was for the purpose of virtualizing black cards. Obviously, Shi Lei did not fully utilize that part of his brain area.

Shi Lei is unknown to the specific percentage.

In order to allow Shi Lei to continue to evolve, the Black Card used the lottery and reputation system to give him many cards. During the use of the card, and over the past year and a half, the battle between Shi Lei and the Black Card has undoubtedly been of great benefit to Shi Lei's brain domain development.

What Shi Lei can be sure of is that the brain domain development and growth caused by the entanglement between him and the black card obviously belongs to him entirely, and this part of the brain domain can be used after it is developed. Then, the brain domain that has been developed but has not been used obviously comes from the brain domain that is temporarily opened when using various cards.

Previously, Shi Lei just thought that when he was using a card, his brain area would be temporarily turned on. When the card's effect disappeared, this part of his brain area would be turned off again.

Now, with the scepter, Shi Lei can judge that after those brain areas are turned on, they will be turned on, and will not be closed again as the card expires.

However, after all, it is a brain domain that uses the energy of black cards, or the energy of those cards to help open it. Therefore, although that part of the brain domain has been turned on, after the card has expired, Shi Lei can no longer use that part of the brain domain. This requires Shi Lei to constantly use those cards in order to gradually put the part of the brain domain that has been opened.

However, the use of 30% of the brain domain is already quite terrifying. After all, even Einstein is only 32% and Shi Lei is not much worse than him.

Compared with Yao Er, Shi Lei has completely won the level of brain development. What he lacks is only various knowledge and common sense in life.

The former is related to whether Shi Lei can handle some complex affairs, while the latter is related to whether Shi Lei can be smooth and comfortable when dealing with life.

He is not as capable as Yao Er to deal with things now, but if he gives him time to learn, he will sooner or later surpass Yao Er.

Shi Lei thought about it and asked again: "How much has Yu Banzhi's brain domain developed?"

The scepter was a little frustrated, and it said dissatisfied: "Silly groundhog, do you want to understand the brain development level of everyone around you?"

Shi Lei said embarrassedly: "It's not that. I just want to compare how much brain development of Yao Er, a guy who is praised by Yu Banzhi as the world's smartest person, is better than that of others."

"What a greedy mole. Forget it, as noble as I am in a good mood today, I will tell you. Yu Banzhi's brain domain development has reached 27%.

"Ah? It's taller than Yao Er?"

"He has lived nearly ten years more than Yao Er. Now he is in his prime. Whether it is physical functions or brain operation, it is the most brilliant stage in his life. What's so strange about Yao Er Gao?"

Shi Lei scratched his head and said, "This means that the level of Yao Er's brain domain development will improve?"

The Scepter did not answer, but it was equivalent to default.

Shi Lei asked again: "What about Dong Chiqing?"

"Silly groundhog, are you still finished?"

Shi Lei heard that the scepter was already very dissatisfied, so he hurriedly said with a smile: "The last one, I promise to only ask the last one."

"Hmph!" The scepter was still dissatisfied, but it finally gave a value: "About 24 percent."

Shi Lei nodded, thanked the scepter, and made a general comparison in his heart.

Among the friends he knows, Dong Chiqing should be ranked very high in terms of IQ and other abilities. Beyond him, except for Yao Er and Yu Banzhi, the other people should not be as good as him.

But considering the age and experience, people like Mr. Bai, Chen Yanu, Ding Yu, Kong Fandong may also be slightly stronger than Dong Chiqing. But others should be killed instantly by Dong Chiqing.

Dong Chiqing has only twenty-four, and people like Old Bai are at most twenty-four and twenty-five.

As a tide-defying existence, Yu Banzhicai is twenty-seven, and he is in his thirties this year. This is almost the peak of his life. At most, it would be amazing to increase by one or two percentage points.

But Yao Er is only in his early twenties this year. He is about the same age as Shi Lei, but he is already twenty-six. With the increase of time and his experience, Shi Lei believes that Yao Er will sooner or later break through thirty.

In this way, the degree of brain development of existences like Wei Xingyue, Song Miaomiao and Wei Qing will be within 22.

Of course, there should be some growth in the future, but the growth will be extremely limited.

Basically after the judgment was completed, Shi Lei spoke again: "The brain domain development of most humans is no more than 20%, which has to be said to be a very regrettable thing."

"Even in the universe we used to be, the brain domain development level of smart species is only 30% to 40%, and only a very small number can break through 50%. A low-level universe like you can reach nearly 20%, which is already a very good evolutionary data."

Shi Lei was surprised by the words of the scepter. In his opinion, the universe where the black card was originally located, the brain domain development of the human beings who dominated should start at least 50% and 60% of them, and some people can even use their brains completely. Unexpectedly, most of the people there were only 30% to 40%, but why was the gap between them so big?

Shi Lei's confusion was only a short time, and he quickly understood the reason.

The Scepter has already said that the universe where the earth is located is relatively low, only three-dimensional. Shi Lei has verified several times that the universe where the black card used to be at least four-dimensional. If it is one dimension higher, the way of looking at problems will be different. The rise of technology is by no means the same way, so it is not difficult to understand that technology is so far ahead.

Seeing Shi Lei dazed, Scepter said impatiently: "Do you have any questions? If not, just return the card quickly. It seems that you are already used to using your barren striking. I will give you more data on someone. Your girlfriend, well, one of them, Sun Yiyi, is born with twenty-five percent of her brain development."

Shi Lei was shocked. Yiyi brain domain development was born with 25%? Wouldn't that mean that she is a despicable being of the same level as Yao Er?

Even higher.

"Impossible? That girl, I can't tell how high her IQ is!"

"That's because of her living environment and experiences, but don't you think that in the past year, when you don't use the supreme black card to give you the ability, your growth is even worse than Sun Yiyi's growth? Everyone has different brain domain openings. Some people may not be able to use all their already-opened brain domains in their lifetime. This was the case in the past. Before she entered university, her brain domain utilization rate was less than 80%.

Shi Lei silently calculated that 80% of the brain domain was 25%, which means that Sun Yiyi's previous brain domain development reached 25%, but she did not use 20 of them. Otherwise, she would have shown her genius long ago.

"If she had been born one by one in a family like Wei Qing, or just Jiang Yuanchao, would she have long been praised as a genius?"
