"The Lord of Eternal Life?" Qi Ling frowned.

This name does not sound simple.

However, he thought about it and didn't come up with the name of which strong man was the Lord of Eternal Life.

"I haven't heard of it." Qi Ling shook his head and said.

"The Lord of Death and the Lord of Life, have you heard of it?" Lin Yifan thought for a while and asked.

But at this time, it suddenly occurred to him that the amethyst space was said to have been picked up by their Lin family's ancestors in the apocalyptic period, if this matter was true...... Then, his master, may have fallen in the apocalyptic era, the situation at that time was said to be very chaotic, and a lot of information was lost, and now, more than five hundred years have passed, and it is also very normal for Brother Qi not to know the Lord of Eternal Life.

"Lord of Death and Lord of Life?" Qi Ling frowned again.

"I've only heard that there is a superlatively strong man whose name is the god of death, and as for the Lord of Death and the Lord of Life, I have never heard of it." Qi Ling groaned.

"Haven't you heard of the Lord of Death and the Lord of Life?"

Lin Yifan's heart sank slightly, could it be that his two senior brothers had fallen in the apocalyptic period?

After thinking about it, he didn't ask the Lord of the Mountains again.

Master said that before he cultivated the Mixed Yuan Wuji Gong to the eighth layer, he should not deliberately inquire about the affairs of the three senior brothers, but wait until he has cultivated the Mixed Yuan Wuji Gong to the eighth layer, and then inquire about the information of these three senior brothers.

Seeing Lin Yifan bowing his head and pondering something, Qi Ling stood quietly and didn't ask Lin Yifan why he asked him these three names.

Everyone has their own secrets, and there is no need for him to get to the bottom of it.

"Brother Qi, don't worry, I will definitely help you avenge your revenge." After a moment, Lin Yifan raised his head, looked at Qi Ling with a firm gaze, and said.

"Yifan, I believe that you will be able to surpass my previous achievements in the future, but I hope that before you are promoted to a ninth-level martial artist, you must not provoke that person, the family behind that person has existed since the end of the world, and it has been in operation for more than five hundred years, and its strength is very strong, and ordinary ninth-level martial artists cannot afford to provoke ......" Qi Ling's face changed slightly, and he said in a deep voice.

"Well, Brother Qi, don't worry, I won't be reckless." Lin Yifan nodded calmly and said.

Ordinary ninth-level martial artists can't afford to provoke them?

Lin Yifan sneered in his heart, he didn't know if he could afford to provoke that family after he cultivated to the realm of a ninth-level martial artist, and then successfully cultivated those martial arts in the amethyst space?

However, in order not to worry Qi Ling, he didn't say these words.

"By the way, Brother Qi, how can you recover from your injuries?" At this moment, Lin Yifan suddenly remembered something and hurriedly asked.

"Unless there are some powerful heavenly and earthly treasures, it won't recover ......" Qi Ling shook his head and said bitterly.

"This injury, the number of my brain cells has lost too much, brain cells are the root of the strength of the brain domain, the root of mental power, a large number of brain cells die, the strength of the brain domain will decrease, and the mental power will decrease......"

"The number of brain cells in a person, once born, will not increase again, and when a person becomes an adult, the number of brain cells will continue to decrease, and only when a martial artist advances, will it increase a little......"

"In the realm of high-level martial artists, the strength of the brain domain must reach the same height, if the number of brain cells is too small, it cannot support the strength of the brain domain to reach too high a level, so the number of brain cells of a person represents a person's martial arts potential in a certain way......"

"Under the same conditions, the greater the number of brain cells in a person, the faster the strength of the person's brain domain increases, and the farther the future will go!"

"Now the number of my brain cells has been reduced to a limit of a fifth-level martial artist, if there is no powerful heavenly treasure that increases the number of brain cells, I can only stay in the realm of a fifth-level martial artist in this life!"

"However, the heavenly treasure that increases the number of brain cells is so precious that it is priceless in the entire Federation!"

"Actually, our conflict with that ninth-level martial artist this time is because of a heavenly treasure that can increase the number of brain cells."

Qi Ling sighed.

"Is there a price in the market? Is it expensive to increase the number of brain cells? Lin Yifan's brows moved slightly.

If he uses amethyst space for smuggling, he can make money at a high speed.

"It's expensive!" Qi Ling nodded.

"You should have learned in culture class that the number of brain cells in a person at birth is about 12 billion!"

"After the age of eighteen, the number of brain cells in a person begins to decrease, under normal circumstances, an average of 100,000 brain cells per day, and if a person exercises excessively, this rate will increase!"

"Hmm!"

Lin Yifan nodded slightly, his expression a little solemn.

He didn't care about this problem originally, at the beginning, he was bent on increasing the strength of the brain domain, and he was bent on breaking through the realm of martial artists as soon as possible, and their head teacher, Pang Long, only focused on these two points!

Later, he transferred to the third (9th) class of high school, listened to Xu Ruxuan's lecture, and coupled with Qi Ling's teaching at that time, he began to pay attention to the damage to the body, as well as the damage to brain cells!

But now, when he heard Qi Ling say this again, he really paid attention to it in his heart!

The number of brain cells seems to be really important!

Ordinary people, if they can be promoted to the realm of martial artists, it is very remarkable, if they can be promoted to the realm of second-level martial artists, the realm of third-level martial artists, it is very powerful!

Therefore, some teachers only value the strength of a person's brain domain, and only value whether this person can break through the realm of martial arts, they don't pay attention to brain cells, which is very normal!

But at this moment, listening to Qi Ling's meaning, if a person wants to be promoted to a more advanced martial artist realm, the number of brain cells of this person is very important!

"According to statistics, only people with more than 11 billion brain cells are eligible to advance to the realm of martial artists!"

"If the number of brain cells in a person is less than 11 billion, it will be very difficult to advance to the realm of martial artists in a lifetime!"

After a pause, Qi Ling said.

"People with less than 11 billion brain cells are not qualified to advance to the realm of martial artists?"

Lin Yifan's face changed slightly.

He hadn't seen this in his culture class.

"In order not to cause panic among the public, this information is a secret information, ordinary people don't know, even if they know, the Federation will not admit it, you don't know this, it's very normal, this information is actually recognized at the level of high-level martial artists!"

Seeing that Lin Yifan was surprised, Qi Ling shook his head and said.

"Only people with more than 12 billion brain cells are eligible to advance to the realm of second-level martial artists!"

"Only people with more than 13 billion brain cells are eligible to advance to the realm of a third-level martial artist!"

"Only people with more than 14 billion brain cells are eligible to advance to the realm of a fourth-level martial artist!"

"By analogy, only people with more than 19 billion brain cells are eligible to advance to the ninth-level martial artist realm!"

"The number of brain cells mentioned here is only qualified to reach that level...... In fact, it is still difficult to break through to that realm! ”

"However, in general, the more brain cells a person has, the faster the person's cultivation speed will be, and the easier it will be to break through to the realm of a high-level martial artist!"

Qi Ling said slowly.

"Brother Qi, I don't know how much our brain cells increase every time a martial artist advances?"

Lin Yifan thought for a while and asked.

According to the data that Brother Qi said, the number of brain cells at the time of a person's birth is only about 12 billion, and it will decrease in normal times, if every time a martial artist is promoted, the number of brain cells of a person increases very little, doesn't it mean that most people are not qualified to be promoted to the realm of high-level martial artists?

"Every time a martial artist advances, the number of brain cells in a person will increase by about ten percent." Seeing that Lin Yifan grasped the key point at once, Qi Ling glanced at Lin Yifan with some appreciation and said.
