The scarlet causal line of the chaotic abyss looked abrupt and hideous in the air, and Zhao Ruhan, who had been an apprentice for more than a hundred years, would still be shocked and tremble by such a demonic causal line.

The chaotic abyss and jealousy, slaughter, and greed are called the four demons of the demon world. According to the "Four Demon Chronicles" written by Sui Liangzan, a scholar specializing in the study of the demon world, jealousy is the best at making people lose their normality through a steady stream of jealousy; Killing is to make people lose themselves in the endless pleasure of killing; Greed and extravagance, with its almost insane greed for wealth, drive people mad; The chaotic abyss is obsessed with chaos and can't extricate itself.

Di Buyan moved the causal line of the chaotic abyss to the causal line of Gongsun and Wu and put it parallel to each other, and said: "The temptation of these four demons to ordinary people in the world is actually the interference of the law of cause and effect. ”

Zhao Ruhan looked at Di Buyan who lit up the two points in time on the causal line of Chaoyuan and Gongsun Chao respectively, and asked when the explanatory text had not yet emerged: "So you suspect that the causal line of Gongsun Chao and Wu Moran was interfered with by the causal law of Chaoyuan?" ”

"No," Di Buyan said, looking at the caption that was gradually emerging, "Of the two, only Gongsun Chao was interfered with by the law of cause and effect. You look at these two points. After speaking, he motioned to Zhao Ruhan to look at the explanatory text at two points in time.

Zhao Ruhan read out the two paragraphs while reading: "In the first year of Hanrenzong's Chang'an, that is, in 940 AD, Gongsun Licheng burned a total of twenty and five books in the southwest annex of Tiancheng Academy.

"On February 21, 940 A.D., on February 21, 940 A.D., high-frequency brain wave activity appeared in Cangzhou's 'that place', and the activity frequency was a new high in 500 years, accompanied by a preliminary blurring phenomenon, with a blurring degree of 2%."

Zhao Ruhan suddenly thought of something, and was stunned for a while: "So...... From、From the first time you burned a book、......? ”

"Yes." Di Buyan lit up the two time points on the cause and effect line of Gongsun Chaos and Chaos Abyss respectively, "You can take a look at this point in time." ”

"On the 17th day of May in the 1st year of Hanrenzong's Chang'an, that is, on May 17, 940 AD," Zhao Ruhan read word by word as the explanatory text slowly emerged, "Gongsun Licheng and his classmate Mei Luosheng became brothers with different surnames. In the same year, Gongsun Licheng drew the 'Trapping Abyss' circle with a large amount of human blood in the southeast courtyard of Tiancheng Academy, and sacrificed the life of Mei Luo Sheng. ...... is this circle?! ”

"Yes." Di Buyan's expression became more and more solemn, "It's the summoning circle that summons the chaotic abyss, continue." ”

Zhao Ruhan moved his gaze to the cause and effect line of the chaotic abyss: "On the 17th day of May in the first year of Hanrenzong's Chang'an, that is, on May 17, 940 AD, the chaotic abyss was virtualized by 25% in Lanzhou. So at this time, the chaotic abyss is actually enchanting...... Right? ”

When Zhao Ruhan ended his sentence so hesitantly, Di Buyan knew that this little girl must be looking at him again, with a face called "Isn't that so?" He nodded and said, "Yes, he's enchanting." ”

"He was planning to enchant Gongsun Chao...... Right? Zhao Ruhan ended his sentence like this again.

"Yes." Di Buyan said coldly, thinking in his heart when you, a hundred-year-old girl, will be able to get through adolescence and become a full-fledged boss with independent thinking ability?

But then again, Di Buyan seems to be used to Zhao Ruhan's babbling character, if she suddenly turns around and is about to leave her one day, she may still be a little lost.

At this time, the babbling Zhao Ruhan looked at the red causal line in mid-air, and her mouth opened widely: "But even if Chaoyuan interfered with her causal line, it only made the causal line between her and Wu Moran appear again after they met, but it couldn't explain why she, a weak woman, could do something big that shook the dynasty." ”

Di Buyan patted the shoulder of the apprentice who broke the casserole and asked the end, and then with a wave of his right hand, Gongsun Chao's cause and effect line "swished" to the starting point of the line segment: "In order to help you figure out this problem, let's go back to the starting point of Gongsun Chao's cause and effect line, that is, the day her father's little tadpole swam to its destination." ”

"Hmm......" Zhao Ruhan couldn't imagine that Di Siming, who had always been serious, would use such a way to describe it, so his old face blushed and he agreed softly in embarrassment.

Di Buyan, who didn't notice her embarrassment, stretched his hands in the air in a relatively opposite direction, and the starting point of Gongsun Chao's causal line was magnified to the size of a wall, and then there was a red line segment on it that was particularly eye-catching by the yellow human causal line.

"This is ......" Zhao Ruhan's mouth opened again when he just closed it.

I saw that this red line segment completely replaced the original yellow human causal line at a certain length stage, and the human life stage corresponding to this length stage is the fertilized egg stage, that is to say, when Gongsun Chao was still a fertilized egg, he was interfered with by the law of cause and effect, and judging from the red color of the line segment, this person is Chaoyuan.

"What did it change?!" Zhao Ruhan was frightened into a cold sweat by the facts he saw.

"We all know that humans have 23 pairs of chromosomes," after looking at Zhao Ruhan and nodding slightly, Di Buyan continued, "22 pairs of them are autosomes, and 1 pair is a sex chromosome. These 1 pair of sex chromosomes ultimately determine the sex of a human being. To put it simply, if the pair of chromosomes is XX, then the sex is female, and if the pair of chromosomes is XY, then the sex is male. ”

Di Buyan walked quickly to the starting point of Gongsun Chao's causal line, pointed to the red line segment and said: "Chaoyuan changed her gender from male to female when Gongsun Chao was still a fertilized egg, and what she did was to change one Y in the 23rd pair of chromosomes to X!" ”

Zhao Ruhan felt that his back was already soaked with cold sweat: "Why did it do this?" ”

Di Buyan waved his left hand, and the cause and effect line of Gongsun Chao moved to the left at an unimaginable speed, and then accurately stopped in front of Di Buyan in 947 AD, that is, the seventh year of Hanjingzong Chang'an.

"In order to make her and Wu Moran fall in love."
