The grandmother sighed softly and said: "Later, the old man of the Du family came back from the capital, and he didn't bring a waiter with him, he didn't know anything by himself, I looked at him pitiful, and came over every few days to clean up for him, and then cooked on weekdays, and also gave him a little relief, which also saved him from starvation." “

Lin Yi suddenly realized and said with a smile: "Grandma is really kind-hearted. ”

The grandmother waved her hand and said with a smile: "In the past, the Du family was not thin on our family, we helped plant those few acres of land, and Master Du did not collect rent from us, but now that Master Du has become like this, I should help a little bit myself." ”

Lin Yi nodded, got up from the chair, and asked, "What is Elder Du writing?" ”

The grandmother said: "I don't know, since the day he came back, he has been writing and drawing on the ground every day, and I can't understand what he writes or paints." ”

Lin Yi stepped out, just to see what Du Jiu was writing.

The grandmother saw that Lin Yi and the others didn't look like bad people, so she stood up and said goodbye: "I've finished cleaning up today, and there are still things at home, so I'll go back first." “

Lin Yi walked to Na Du Jiu's side, squatted down to look, and saw that the ground was densely covered with numbers, in addition to numbers, there were also several arched bridges drawn.

Lin Yi looked at the patterns and numbers of the arched bridges on the ground, and she roughly understood in her heart.

This Du Jiu because the bridge built was unqualified, and finally collapsed, so he was dismissed from his official position by the emperor, thinking that after he was deposed, he never gave up, and wanted to find out the reason for the collapse of the bridge.

Even in his heart, he wanted to build an arched bridge that would not collapse in his lifetime.

According to the history of modern learning, our earliest arch bridge was built in the Sui Dynasty, so this Tianchi country should be before the Sui Dynasty.

However, there is no record of this Tianchi country in the history books, and it may be that this is another time and space at all.

Lin Yi's thoughts flew in her heart, putting aside those thoughts of time and space, Lin Yi pulled her thoughts back to the present, she stood there, didn't speak, just silently watched Du Jiu write and paint.

In the end, after all, it was Du Jiu who collapsed first, raised his head, glanced at Lin Yi indifferently, and asked, "Didn't Grandma just say that I don't take any engineering work, what are you still doing here?" ”

Lin Yi smiled: "I originally wanted to ask you to help me build a house today, but when I saw the painting you wrote on the ground, I suddenly didn't want to invite you." ”

Du Jiu snorted coldly, ignored Lin Yi, and continued to bow his head and draw his own.

Lin Yi beckoned to Ji Qianmo and said, "Jin Dou, let's go." “

Ji Qianmo walked to Lin Yi's side, took his hand, and prepared to go out.

Lin Yi's fingers scratched lightly in his palm, leaned over to his side, and whispered in his ear: "Jin Dou, ask me why I didn't invite him." ”

As soon as Ji Qianmo heard this, he understood Lin Yi's thoughts, and immediately pretended to be ignorant, and asked loudly: "Daughter-in-law, Doctor Zhang Xiaotai said that Du Jiuye's ability to build a house is good, why don't we invite it?" ”

Lin Yi smiled: "Didn't you see him write on the ground just now?" Even I, a thirteen-year-old girl, can calculate the topic, he can't calculate it for so long, do you say that with this ability, can you still build a house? If he had real talent and learning, he would not have built a broken bridge and been punished by the current emperor, I see, our house, it is better to invite another master with better skills. ”
