When the last classmate gave up calculating the answer with Zhuo Chuan, Zhuo Chuan had already memorized for a full hour, and even the end of class time had passed, and at this time he had already calculated to more than 4,000 decimal places.

"Okay, Zhuo Chuan, you can stop" Feng Lan finally relented, reached out and touched her brows, she was already wrinkled a line, she felt that she couldn't continue to follow.

"Zhuo Chuan has made great progress, from a simple multiplication of 7 digits can't be calculated, to now can be calculated in real time to thousands of digits, it is not easy, everyone will learn more from Zhuo Chuan in the future" She reluctantly praised Zhuo Chuan.

Although Zhuo Chuan is an adult, no one doesn't like compliments, even old men.

"What the hell is ......" After complimenting, she glanced Zhuo Chuan up and down again, couldn't help muttering, and announced the end of class, "Okay, this class will come here first, the next class is a history class, this time we are going to learn a secret history, the length of this secret history spans more than eight hundred years"

After class, Zhuo Chuan was surrounded by classmates.

"Uncle is developed this time,"

"Yes, in terms of computing power, I have crushed a genius, in the end, I am the successor of a B-class citizen, and it is different when I wake up"

"No wonder the last time I came, my uncle behaved very confidently, and it seems that he is confident"

"Then why don't we celebrate the uncle tonight and wish him victory in the duel?"

Zhuo Chuan was also a little moved when he heard this, he hadn't attended the party for a long time, but he was an adult after all, and he had seen a lot when he was successful at the moment, and now he was still sober, although compared to more than a month ago, the progress can be said to be huge, however, he can still clearly know that he still lacks the key to the final word.

That is, he has not yet comprehended an offensive soul skill, or mastered the special technique that Lao Xu said to break the defense of soul power.

Neither of these two keys to victory has been grasped, and there is still a month left in the clock, although he now has great confidence to grasp it, but until it is transformed into real strength, it is useless.

"No, I still have to continue training, time is still very tight," Zhuo Chuan understood this fact, of course he would not do such a thing.

"By the way, you and Teacher Feng Lan will talk to you in the next class, I'll go to the sports training hall" Since Zhuo Chuan has determined that his computing ability has increased, it is enough to cope with the digital thinking training in the new world, and he does not want to participate in the following history course, after all, no matter how good history is, it is not of great use to him at the moment.

"The next class is a history class taught by Teacher Feng Lan, since she predicted in advance that she was talking about a secret history eight hundred years ago, you should listen to it, after all, these secret history materials are very precious, and they cannot be disseminated online and privately, because of the lack of reliability, except for the relevant teachers who can get the permission of teaching, others do not have the right to disseminate, but after everyone listens, some people may get some understanding," Fu Yun, the female class leader, came over and said.

"This," Zhuo Chuan thought for a moment, because of the restriction of one soul teleportation in six hours, the body of the new world is very strong, but it also needs to be taken care of at least once a day, which means that the time to stay in the modern world to absorb the power of the soul every day is at most eighteen hours.

"Okay then, but I remember why Feng Lan had never told this kind of secret history before? At least I've never heard of it for more than a month in class," Zhuo Chuan was puzzled again.

"Because Mr. Feng, every time before we have the final exam, we will talk about some secret history, these knowledge that is not circulated on the public network information, will help us gain a unique advantage, last time I told you, the end-of-term survival trial, is one of the final exams, for us underground reserve citizens who have not undergone any physical strengthening, it is very difficult, although the accident mortality rate is extremely low, and it is not as good as the car accident rate before the invention of unmanned driving, but this is also the only normal exam that will die." Fu Yun seemed to have thought of something, and his face darkened.

This is the first time Zhuo Chuan has heard that there are still accidental deaths in this world, because he has never seen any car accidents on the Internet, natural disasters can take away people's lives, and these, in the modern world, do not see ten or eight cases on the Internet every day, then God bless.

He naturally didn't bother to inquire at this time, and nodded, "Then I'll stay and listen to this secret history."

It didn't take long for Zhuo Chuan to understand the preciousness of this decision, at least it was worth it compared to going to the fighting room for a training session. As soon as Feng Lan spoke, he knew that this lesson was specially prepared for him by the other party.

"We humans have discovered the power of the soul, the existence of the soul skill, has a history of more than nine hundred years, sorry, I used an estimated number, although it is only a thousand years away, and human beings have entered the stage of thorough civilization thousands of years ago, and there have long been various storage devices, but the official historical record of the discovery of soul power in the early years has been wiped out, and we can only get some information from the occasional memories of some people, and deduce that the soul power first appeared in a hundred years ago in a hundred years ago, The secret history I am talking about below comes from the memories of a man."

Speaking of this, Zhuo Chuan and Feng Lan glanced at each other, and the other party didn't care about him, but talked about himself.

"This man has lived for more than eight hundred years, and he once recalled the events of the early Century Rebellion, and mentioned a phenomenon, that is, more than two-thirds of the core skills of the soul skills he has mastered now were learned in the Hundred Years Rebellion, and in the years of peace that followed, he gradually mastered only a few of them,"

…………

The secret history is very long, but Zhuo Chuan has memorized it without a word. Most of what Feng Lan said was the scene where the person comprehended the soul skill several times, and only one of them was comprehended in peacetime, and the others were comprehended at the moment of life and death.

What he comprehended in peacetime was a skill related to production and life, which he spent decades accumulating, and what he comprehended at the moment of life and death, but it was closely related to combat, and it was comprehended in a very short time.

This is easy to understand, after all, the environment determines the direction of human evolution, and pressure determines the speed of growth, and the creatures in the sea do not evolve as fast as on land. The smartest creatures in the ocean can only be treated as pets and protected animals by humans.

The content is not shocking, but Zhuo Chuan was awakened, and there is a direction, he wants to comprehend the offensive soul skill, it is possible to comprehend it in life and death, the risk is naturally great, but at least it is a possibility, it is better than not knowing the clue.

Zhuo Chuan kept this reminder in mind, but because of the risk, he wouldn't use it immediately, after all, now he can still absorb the power of the soul, and after absorbing the power of the soul, he can also appear new abilities, never forget, and terrifying mental arithmetic, all of which appear passively after absorbing the power of the soul, and he hopes that as he continues to absorb, more powerful new abilities will appear, so that he does not need to bear the risk of death.
