Yu Qingxue proposed to provide Yu Zhesen with guidance on mental protection training.
"If you insist on continuing to investigate the nightmare in depth, you must accept my proposal." She said.
Yu Zhesen was surprised by her attitude: "Why...you have to do this?"
"I support all your actions in using your abilities for the right things."
Yu Qingxue's tone seemed very calm, and she suddenly added: "The duty assigned to me by the Supernatural Power Investigation Section is to examine dangerous superpowers, not to turn geniuses who are beneficial to society into mediocre."
"Genius? Me?" Yu Zhesen was a little unsure.
"It's just a metaphor."
Yu Zhesen calmed down and asked for advice: "Last time you said you could teach me how to fight against the intrusion of thoughts, so where do I start?"
Yu Qingxue glanced at the environment in the conference room and said, "If you have nothing else to do, you can start now."
Seeing that Yu Zhesen had no objection, she turned on the projector in the conference room, and then chose to sit down with her back to the projection screen.
"Start with the simplest part." She said, "You can now put a number on the projection and then recite the number silently in your mind."
Yu Zhesen did as she asked and entered the number "42" on the screen through the microcomputer on the long conference table. He looked at the screen and kept reciting the number in his mind.
Yu Qingxue stared at him, put her hands on the table and clasped them. After two seconds, she slowly said: "It's 42, right?"
This result is not surprising at all. Yu Zhesen knew that she had such an ability, but he was just eager to know what he needed to do to avoid the intrusion of her mind.
"Now I'll give you a few minutes to prepare, think about the next number, and try to interpret it with unconventional thinking." Yu Qingxue said.
Yu Zhesen felt confused: "What is unconventional thinking?"
"For example, in radio codes, replace the number with a symbol that only you understand."
"But even if I create this set of passwords, won't they still be stored in my mind?" Yu Zhesen asked puzzledly, "For you, it's just a matter of reading more information."
Yu Qingxue smiled: "You want to fly before you even learn how to walk? You can first make a replacement code."
It seems that this is a step-by-step teaching, and Yu Zhesen has understood her ideas of mental protection - disguise, deception and concealment, just like the intelligence war between spies and radio interceptors on both sides during the war.
He pondered for two minutes, and finally cleared the 42 on the projection screen and randomly entered a new number "59".
Yu Zhesen designed a simple password. He split 59 into two numbers, 5 and 9, and replaced them with the fifth heavenly stem "五" and the ninth "ren" among the heavenly stems and earthly branches respectively.
He silently recited "Wu Ren" in his heart and expressed his readiness to Qingxue with his eyes.
Yu Qingxue looked at him in silence for about ten seconds, with a look of approval in her eyes: "This time I can no longer solve the problem just by capturing your thought fragments. Characters are more difficult to read in thought fragments than numbers.
”
She activated her ability on Yu Zhesen.
"Wu Ren, what about the Heavenly Stems and Earthly Branches? Have you set a password for each digit of the Heavenly Stems and Earthly Branches from 0 to 9?"
Yu Qingxue smiled.
"Although you can directly guess that the number you want is 59 based on the order of the heavenly stems, telepaths should not use guessing when they can directly obtain information."
She further read Yu Zhesen's thinking and determined that the numbers "E" and "Ren" corresponded to him were 5 and 9 respectively.
"59, well done."
Yu Zhesen smiled bitterly: "So I think there is no point in doing this. Even if you set a password, you can still crack it in one go."
"But this time I spent more time, and there was also mental exhaustion that cannot be accurately measured with numbers."
Yu Qingxue explained patiently: "The current teaching and training is in an absolutely quiet environment, with only the two of us, and focuses on the attack and defense of thought intrusion. This is an 'ideal environment' that only exists in training. In actual combat
At that time, telepathic superpowers rarely had the opportunity to read your thoughts so focused on it."
Yu Zhesen somewhat understood: "So the mental protection training is to improve my information encryption and hiding capabilities. It is not to completely eliminate thought intrusions, but to try to increase the difficulty for the intruder to obtain key information and delay his time?"
"That's right." Yu Qingxue nodded affirmatively, "The longer it takes to interpret your thinking, the higher the probability that the other party will miss the key information in your thinking."
While Yu Zhesen was thinking about these words, she continued: "You don't have to think too much about people with telepathic abilities. Although powers such as mind reading can peek into your thinking, you have to peel off cocoons from the vast sea of thinking.
Finding key and useful information is not easy."
Yu Zhesen was eager to try: "Try again?"
"Okay, nod and tell me when you're ready." Yu Qingxue readily agreed.
Yu Zhesen only took a short time to enter the numbers this time.
He nodded and smiled at Qingxue.
Yu Qingxue blinked, concentrated on breaking through his outer thinking area, and started to invade.
Soon, a slightly surprised expression appeared on her face.
The information in Yu Zhesen's mind was very clear. She read it completely, but she was stunned.
A poem.
"I had to walk the same path as the martyrs and the clowns."
Yu Qingxue was a little confused for a moment, and she asked: "Our topic is to guess numbers, right?"
"Of course."
Yu Qingxue calmed down and went deep into Yu Zhesen's thinking again.
Could it be that Yu Zhesen chose a long string of numbers? Although she originally intended to use numbers within 100 for basic training, she was not afraid of Yu Zhesen choosing a long string of numbers.
The question now is what has this string of numbers been replaced with? Is this poem as a whole? Or is it decomposed into individual characters?
The main subject of Yu Zhesen's thinking has always been this poem. The poem itself is very conspicuous and not hidden at all.
It took Yu Qingxue a full three minutes to eliminate the wrong ideas. She was already surprised in her heart by Yu Zhesen's learning ability.
"17, right?" She finally found the answer.
Yu Zhesen nodded.
Yu Qingxue turned around and looked at the projection screen behind her. It was indeed the number 17.
"It's very well done. There are 17 characters in this poem. You use it to refer to the number 17. This set of thinking is very advanced even for a telepathic person like me." Yu Qingxue praised sincerely.
.
"But I only blocked you for four or five minutes." Yu Zhesen was not satisfied.
Yu Qingxue opened her mouth and said quietly after a while: "For a beginner in mental protection, isn't it something to be proud of if you can block me for five minutes?"
"If I continue to improve, can I delay it longer?"
"There are opportunities, but don't separate training from actual combat, otherwise it will just be talk on paper." Yu Qingxue said, "All training does is let you master theoretical ideas, and don't fall into formalism and dogmatism."
Yu Zhesen was in high spirits: "Continue?"
Yu Qingxue shook her head slightly: "That's it for today. If I continue, I'm afraid I will have to take a second injection of Flora."
