Daming: Grandpa Emperor, please get up and sit on my throne!

He is confident in Ma Sanbao's work.

Moreover, Zhu Yunhuan had heard about the evil deeds these two had done in the past. Zhu Gang was a mixed bag of good and bad, and he seemed to have restrained himself a lot in the later period. The second brother, Zhu Chong, could be said to be a man of evil. In history, he was poisoned to death by someone in his own mansion, and Zhu Yunhuan scolded him as "deserving to die."

There is definitely no shortage of memorials and charges against them.

As Zhu Yunhuan flipped through the files, the Qianqing Palace fell silent, with only the occasional sound of flipping pages and the extremely subtle sound of burning red charcoal in the brazier.

Ma Sanbao was also doing what he was supposed to do.

Time passed slowly.

When Zhu Yunhuan narrowed his eyes slightly and raised his hand to pick up the pen to circle a satisfactory name on a piece of paper with his imperial red brush, a sound of gasping for breath was heard from the backyard of the Qianqing Palace: "Hiss... This... This!?..."

The voice did not come from someone else, but from Ma Sanbao.

Zhu Yunhuan frowned slightly, put down the imperial calligraphy in his hand, raised his eyes and looked towards the backyard. At this time, Ma Sanbao also ran over anxiously with a look of being faced with a great enemy.

"What's the matter?" Zhu Yunhuan asked. He knew that Ma Sanbao was careful and steady in his work and was not the kind of person who would make a fuss.

Ma Sanbao was seen frowning.

With a solemn expression on his face, he lowered his voice and said to Zhu Yunhuan, "Your Majesty... something bad has happened! The leaves of that vine you planted in the backyard, that 'sweet potato', seem to be turning slightly yellow for some reason!"

Ma Sanbao still doesn't know what that thing is.

But he knew how much his master valued him - he hoeed the fields and planted the crops with his own hands, looked at them every day, and kept them warm with charcoal fire to maintain the temperature like spring and summer. He was even willing to bear many insults such as "naughty", "willful", and "unfilial" for this.

No matter what it is, it must be something extremely valuable.

The leaves are turning yellow now.

Ma Sanbao was naturally anxious, even speaking incoherently: "This... the area around the sweet potato is neither too hot nor too cold, and people feel very comfortable here. It's being cared for so carefully, so how... how could this be..."

As he spoke, Ma Sanbao was sweating profusely in the middle of winter.

however.

He stood there worrying to himself for a long time.

Only then did he realize that his master was obviously very nervous about the green vines, but when he heard his words, he didn't look anxious at all. Instead, he had an unusual smile on his face and his eyes were shining.

Ma Sanbao looked bewildered and could only think to himself, "Your Majesty... could it be that Your Majesty has fainted from worry?"

After a pause, Zhu Yunhuan thought for a moment, then immediately stood up and said expectantly, "I'll go and take a look."

Ma Sanbao didn't dare to say anything more.

With a solemn expression, he followed Zhu Yunhuan's footsteps and returned to the backyard...

Zhu Yunhuan was not a person who showed his emotions on his face, or rather, he had experienced and seen a lot, and few things could cause him to have big emotional fluctuations.

Of course, sweet potatoes are an exception.

At this moment, he just looked happy and expectant.

His heart couldn't help but beat wildly, and he took two steps at a time and came to the sweet potato vines that he had planted with his own hands.

As he brought a slight breeze, a few leaves with yellowed edges under his feet swayed slightly.

He stood still and was silent for a moment, then took a deep breath and said with some emotion: "The weather is getting colder, and the leaves are turning yellow..."

"The leaves are turning yellow, and it's not far from harvest time!"

Crops such as potatoes and sweet potatoes are eaten for their rhizomes. In the later stages of their growth, the stems and leaves wither, and the lower leaves turn yellow and fall off. The nutrients in the leaves will be slowly transported to the sweet potatoes in the soil, which is a period of rapid expansion of the rhizomes.
