The old man is still happy, looking like Lao Tzu is joking without saying anything.

The other people, except for the two grandsons of the Liu family who were a little nervous, the rest of the adults looked very calm.

Feeling the relaxed atmosphere of eating melons in this family, Yan Bei's heart finally fell halfway.

Zhang Hong retreated from the balcony and said to Yan Bei with a smile: "When Lao Wang left, he came to my house to explain it again, saying that he was not at home during this time, let us take care of your mother and son more." ”

"Isn't it!" Liu Ying also walked over, this is Wang Xiaoming's aunt, she stared exaggeratedly, and said loudly:

"Don't say it, Ren Lao Wang looks like an elm pimple, but people still know that they love their wives and children."

"yes, I really can't see it on weekdays." Zhang Hong also joked with a smile.

When Yan Bei looked at them like this, he knew that the purple vortex in the sky was not expected to have any impact on himself and the others.

Chong smiled embarrassedly at the two and asked curiously, "What is the purple vortex outside?" ”

Hearing her ask, Liu Wenbo, who was standing by the window, explained: "That's a formation, there may be masters fighting, but don't worry, there is a formation, they won't affect innocent people." ”

"Formation?" Yan Bei looked over suspiciously, she had never seen such a formation before.

Liu Wenbo nodded, and explained with a light smile: "This is a conic curve equation formation that can only be understood by high school students, although it is not the first time I know this equation formation, but this is the first time to feel the power of the conic curve equation formation." ”

After speaking, he looked at the whirlpool in the sky with envy on his face, and sighed: "Alas~, I think when I took the high school entrance examination, if I hadn't fallen in love, I should have become an excellent high school student now." ”

Hearing this, Rao already knew that this world was such a strange setting, and Yan Bei couldn't help but twitch the corners of his mouth.

Putting down Wang Xiaoming in his arms, and asking Grandma Liu to watch, Yan Bei walked to the balcony and looked at the huge whirlpool outside through the window, and somehow, he suddenly lost his fear of it.

She tried to read silently in her heart: "Chibi Fu, the autumn of Renxu, the hope of July, Su Zi and the guest are boating under the red cliff." The breeze is coming, and the water is not rippling. Raise wine and belong to the guest, recite the poem of the bright moon, and sing the chapter of the slender ......"

Silently, he couldn't control his muttering.

The crisp voice, with the sonorous and powerful tone, with the display of the whole word, everyone in the room seemed to sense a stable force, suddenly quieted down, and the world in front of them changed, as if entering some kind of mysterious and mysterious world.

The purple vortex in the sky no longer seemed to be just a simple vortex, they raised their eyes to see, and in the purple, where they couldn't see anything, two figures suddenly appeared, one black and one white.

The black shadow turned left and moved, and the white shadow bullied up, and the two of them had words in their mouths, the black shadow recited one ancient text after another, while the white shadow typed out one complex mathematical symbol after another.

There are log, ln, cos, tan and other mystical symbols, only to see Liu Wenbo's head swelling and pain, he just graduated from junior high school, he can't understand the mystery of high school mathematics at all.

And Liu Ying, Zhang Hong, and Grandma Liu had already been defeated, and they were holding their chests and gasping for breath, obviously it was not hot today, but the foreheads of the three were covered with fine beads of sweat.

However, Old Man Liu is still as usual, the corners of his mouth are slightly raised, and he seems to have integrated into the mysterious world full of mathematical mysteries.

Suddenly, a strong mysterious energy suddenly attacked, waking up Old Man Liu, who was contemplating, and at the same time causing Yan Bei to frown.

She didn't think about it, it was almost an instinctive reaction, and she directly shouted: "Hydrogen, helium, lithium, beryllium, boron!" Carbon, nitrogen, oxyfluorone, neon! ”

As soon as the periodic table of chemical elements came out, a layer of white defensive enchantment immediately appeared in front of Yan Bei, firmly protecting her and the few people behind her

The powerful defense directly rebounded the mysterious energy that attacked.

After a while, I heard a scream of "ah" from the window, followed by the sound of a heavy object falling on the ground, and finally fell silent.

Everyone in the Liu family looked at the woman in front of them in shock, and they couldn't believe that the fatal blow that came to the high school student just now was actually defused by her like this.

Of course, they can't understand why they, as melon-eating people, are attacked like this.

The purple vortex in the sky had disappeared, and the two black and white figures in the sky had disappeared from the sky.

I don't know what I remembered, Liu Wenbo hurriedly bent down to look at the flower bed downstairs, and saw a white figure fainting in the flower bed, with blood at the corner of his mouth, I don't know if he is dead or alive.

"Grunt", Liu Wenbo, who had never seen such a big scene in his life, swallowed his saliva fiercely, and then turned his head to look at Yan Bei, who was surprised in the room, and weakly reminded:

"Xiao Yan, what if someone dies?"

"What should I do?" Yan Bei put away his surprise, looked down downstairs, and unexpectedly met a pair of black eyes.

It was the black shadow, and at this moment she was standing beside the white shadow with blood in the corner of her mouth, looking upstairs.

"Thank you." A soft voice spat out of her mouth, and Yan Bei blinked his eyes to make sure that he had not mistaken the golden halo above her head, so he reluctantly pulled the corners of his mouth and replied:

"It was an accident."

If it weren't for the man in white attacking her first, she would just continue to eat melons instead of beating him like this.

Of course, there was one thing that she had completely unexpected, and that was the power of the periodic table of chemical elements.

These simple ten elements, in fact, junior high school students have learned, but I didn't expect it to play such a big role.

Could it be that the more knowledge people have, the stronger the effect of using it?

Xiang Meili saw that she was actually stunned, so she could only show a helpless smile, said thank you again, and then picked up the man in white who didn't know whether she was alive or dead.

After all, the matter was provoked by her, although I don't know why this woman suddenly helped her halfway, but she can't leave trouble for others because of this, she must solve her own affairs.

When Yan Bei was still thinking about the power system of this world, Xiang Meili had already disappeared.

The Liu family looked at her in surprise, completely unable to believe that the neighbor they had been with for so many years was actually a high school student.

"Xiao Yan, I didn't expect you to be a high school student!" Liu Wenbo said in surprise.

The rest of the Liu family nodded one after another, and the eyes of the two children of the Liu family who looked at her were already full of stars.

Of course, the most shocking was Wang Xiaoming, because he never knew that there was such an existence as a high school student in his ordinary family.

Moreover, this high school student turned out to be his mother.
