Hu Zijing followed Xiao Lian to the bedroom. The back of the desk surprised him.

Until the two of them walked to Chu Yiyi's side, she didn't notice it at all, and still muttered softly in her mouth, looking extremely focused.

"You see, I'm not wrong, Mom went crazy." Xiao Lian tugged at Hu Zijing's trouser legs on the side.

Hearing the voice, Chu Yiyi turned around as if he had just woken up from a dream. His gaze shifted from the innocent-looking Xiao Lian to Hu Zijing. His gaze was soft at the moment, and he actually showed a little appreciation.

"Wait, don't go yet." She got up and moved a stool, which she placed next to her own, "Sit here!" She patted the stool and looked at Hu Zijing who was stunned.

"I have a few questions for you." Her expression was serious, as if an archaeologist was trying to explore some hidden secret.

"Huh?" He sat down, glanced at the books spread out on the table, and frowned slightly.

These books are all newly bought, and when have they been painted so unrecognizable. The line spacing, which was not spacious enough, was filled with dense small print, and the entire page of the book seemed to be glued together, unable to be distinguished.

He picked up the book and flipped through a few more pages, only to find that the whole book was densely packed.

"Explain, what is this pH?" Chu Yuyi's eyes blinked, full of curiosity and desire to learn.

"Soil pH, also known as "soil reaction". It is an acid-base reaction of a soil solution. It mainly depends on the concentration of hydrogen ions in the soil solution, expressed in pH. ”

Chu Yuyi looked at him blankly.

Xiao Lian looked at the two of them and felt bored. Unexpectedly, even his father went crazy with him, he shook his head and walked out of the room.

"Let's put it this way, if the red soil has a small pH, the area can be planted with acid-loving tea trees, and alfalfa is strong alkali resistance, so it can be planted in places with a high pH."

"It seems to be somewhat understood. It's like although you and Brother Ziyao are brothers, but you have a bad temper, Brother Ziyao has a good temper...... Those with a bad temper need to use force, and those with a good temper need to use literary ......" Chu Yuyi was happy with the metaphor, and didn't notice that Hu Zijing's face was gloomy.

"A bad temper may be violent." The voice pierced into the eardrum with a coldness.

She seemed to be able to see the black lines on Hu Zijing's forehead, as if she was about to eat people. Hurriedly changed the subject, "What about this...... I've heard of this grafting and cuttings, but what is the fast propagation of rose tissue culture? ”

She gestured to that line.

"Take the young stem segments as explants, and propagate them with axillary bud culture and stem segments as subgeneration...... he said unhurriedly. Chu Yiyi listened attentively.

These are the books he has read in his study whenever he has free time since his father asked him to take over the company. It was a bit boring for him, and at the time it was only a pastime, a little dabbling. I didn't expect this woman to be able to read so many questions, and remembered that Brother Ziyao once described her as Ben 100,000 whys, which is really appropriate.

"What are you laughing at?" Chu Yiyi looked up and saw that he had been careless, and he actually smiled slightly at this moment. Do you think she's stupid?

He retracted the smile on his lips, his eyes rolling slightly, "I'm a little thirsty." ”

His voice was indeed a little hoarse, it must have been too much just now.

Chu Yan went to bring tea as he wished, and offered it to him respectfully, "Your tea." ”

Although he was very thirsty, he still drank it without hurrying or slow, as if the tea had to be tasted carefully to get the true meaning.

"I'll go to work tomorrow...... Nervous? "I saw that she had done so much homework and taken notes on everything. It's the first time I've seen her so attentive.
