Son of Heaven

Chapter 19: Heartstrings Half an hour later, the room immediately became tidy. Although the windows were not bright, at least all the things that should be tidied up were tidied up, and it was not as messy as before.Although there are occasional cigarette butts on the ground, at least, now Liang Chen already has a place to lay his feet.For Li Xiang who has never cleaned up the house, this is already very rare. "Let's start class." Liang Chen walked into the room, without even looking at her, sat down and opened his military bag, and took out a third grade mathematics book. "Okay, okay, teacher." Li Xiang stammered, but then she was dumbfounded. She has become a habit of skipping classes. How can she remember where her textbooks are? "Huh? Is there any problem?" Liang Chen frowned, and raised his eyes to look at her. "I, my textbook, I lost it..." Li Xiang was most afraid of his seemingly calm but incomparably stern expression, so he shrank back desperately, his voice trembling a little. "Use mine first." Liang Chen didn't get angry, he pushed his textbook forward, and said calmly. "Yes, yes, teacher." Li Xiang answered, but dared not come over. "Huh?" Liang Chen snorted lightly, and frowned again.Li Xiang was trembling all over, so he had to bite the bullet and walk over to sit on tiptoes carefully, his buttocks only dared to touch the stool a little bit, staring at the book, not even daring to take a breath. "You're just in the third year of junior high, right?" Liang Chen nodded when he saw her sitting down, and asked. "Yes, teacher." Li wanted to nod desperately, fearing that his attitude would be bad or that this teacher would be dissatisfied, and then he would take care of her. It is still fresh in Li Xiang's memory. "Well, I just started school, so I probably haven't learned too much new knowledge. Let's review the old knowledge first, starting with mathematics. You can talk about the classification and concept of numbers first." Liang Chen nodded, "Numbers The categories include natural numbers, integers, rational numbers, irrational numbers, real numbers, and complex numbers, and the specific concept is..." Li Xiang quickly used his brain to answer Liang Chen's question. "What's the algorithm of real numbers?" Liang Chen didn't take the book, but he remembered the distant junior high school knowledge points extremely accurately and solidly, as if every word in the book had been engraved in his mind. "Including addition, subtraction, division, multiplication and mixed operations, the law of addition is..." Li Xiang didn't dare to be negligent, and answered non-stop.I have to say that although this Rainbow sister looks like a standard young lady, she can see that her previous foundation is quite good, and she remembers these knowledge points quite firmly. Glancing at her, she was immediately frightened and remembered.From the knowledge points in the first year of junior high school, to the first half of the second year of junior high school, all the knowledge points are well remembered, but from the second half of the second year of junior high school, it is basically a mess. After asking a few questions, Li Xiang was speechless and unable to answer. I couldn't help but start to sweat on my forehead.Liang Chen didn't say anything else, and changed his subject, this time the exam was English.For this homework, this rainbow sister has an amazing talent. Not only can she answer the knowledge points fluently, but she can also use an authentic Oxford accent to talk to Liang Chen. The grammatical tense is extremely accurate, and there are few mistakes. Liang Chen guesses the least. Should have a college English level around CET-[-], it seems that he has worked hard in this area.
