"Father, these books..."

"Those ministers said there was no way to govern, but I just didn't believe it. I fought south and north, and I had nothing to do after many years? Now I just want to control the river, how can I be rare to fall down?! The ministers never proposed a tree matter like this, but I found it out!"

Liu An didn't say much, and sat directly beside Ah Father and looked at the books in front of him.

"By the way, has my father read the book of the geography master?"

"No..."

"I remember that their books have drainage methods. I built drainage facilities for the King of Wei in China... I'll look for it. There are also trees planting in this farmer. Actually, I think that planting a large number of trees in the middle and upper reaches is still of great use..."

Liu An quickly found a few books, but Liu Chang couldn't even understand the title of the book.

The father and son talked seriously and wrote, and more and more books were piled up in front of them.

At some point, when Liu Chang recorded a successful method again and was about to ask Liu An, he found that the man was lying on the eucalyptus and was sleeping soundly. Liu Chang looked out the window and it was already late at night. Liu Chang put down the melody in front of him, bent down, gently picked up his son, and walked out of Tianlu Pavilion.

The breeze was gentle, and Liu Chang's arms were so stable, holding a half-aged child, not moving at all.

Liu An slept soundly.

ps: I have been on the plane for nearly five hours and have arrived at home and exhausted. I don’t know if I can write it out in Chapter 2...
Chapter completed!
