Li Feng resisted his temper and patiently explained: "But a big country resembling a large rundown house, with wind blowing from four sides, as soon as there is rain, one will have to work hard to pull down the east wall to make up the west wall. Is there any place that does not have to be stretched?"

Gu Yun sneered inside; it was not convenient for it to be shown on his face. Thus he only feigned indifference.

"The ground is cold, I can see Imperial Uncle's complexion is not good, even the scent of medicine on your body has not scattered yet, don't keep kneeling like that." Li Feng seemed to have cooled down, trying to be sensible with Gu Yun, "I remember as a child, Tutor Lin had said: the power of a country lies within the two arms - 'God-sent' and 'Man-made'. Does uncle remember?"

Gu Yun: "I do. 'God-sent' are mountains, grass, grains, soil and fish, the Ziliujin underground; 'Man-made' are the teachings passed down from previous wise men, industrial and trading, craftsmanship, machines, and armors. These two, resembling the beams, can still stand if one of them remains, but both cannot be broken at the same time; a ruler should remember this."

"Imperial Uncle has truly memorized all that you have read," Li Feng lowered his eyes and looked at him. "Now these two beams have both been hollowed out by insects, what am I supposed to do?"

Gu Yun actually wanted to reply: "If you weren't pushing the implementation of that ridiculous Zhang Ling Law, perhaps there would not be so many insects," but it was useless to say so. Just look at Master Feng Han, now hugging his dog children to reflect on his actions behind closed doors.

One asking and the other one answering reminded Li Feng of when they used to study together at a young age. When Gu Yun was a child, his body was in poor health, and he always fell ill, all day taking medicine. His personality was no better either, never caring for anyone. However, towards his brothers, he was very aware of his role as an 'uncle'. Although he was even younger than Wei Wang, whenever there was anything delicious or fun, he would always save it for them, never fought for it, or kept it to himself. When questioned, he would answer; when asked, he would give. Li Feng had once liked him very much.

"Get up," Li Feng's last bit of anger faded. "Imperial Uncle is the sharp blade of this country, I still need to rely on you to stabilize all four sides."

Gu Yun heard his words, slowly bent over, his forehead slightly touched his fingertips on the ground.
