He simply couldn't understand what kind of person in Hekou County could mobilize so many people to dig up the sweet potato and potato seeds at once.

Just when Zhu Yunwen was at a loss for what to do, he could only make the decision to go and see the dug-up fields to see where the problem lay.

So Zhu Yunwen went out of the city again and went to some fields to conduct on-site inspections.

Walking outside the field, Zhu Yunwen looked inside and found that the field had been dug up in a mess.

The sweet potatoes and potatoes that were originally planted were completely stolen, not a single one was left.

Zhao Qingzhu asked with some confusion:

"This is too strange. How could such a large amount of work be accomplished so easily?"

Zhu Yunwen also frowned: "The issues here are far too complicated."

After thinking carefully for a moment, he searched the field again.

Finally, they found a small piece of sweet potato in a patch of soil in the field.

He picked up the small piece of sweet potato and looked at it. This sweet potato was not planted as a whole as before, but was a part of a whole sweet potato.

It looked like something had gnawed it down.

Zhu Yunwen then carefully examined the gnaw marks, compared them with several other bite marks, and then frowned and said:

"It really was man-made!"

Zhao Qingzhu asked, "How did Your Highness discover this?"

Zhu Yunwen took a deep breath:

"The teeth marks on this sweet potato are human teeth. It was nibbled on haphazardly a few times and then thrown on the ground. It seems that when digging up sweet potato or potato seeds, one gets hungry and can't help but eat these seeds."

This sweet potato can be eaten raw, and it was quite large. The fact that only a small portion remained indicates that the person was very hungry. However, after eating more than half, they couldn't finish it because it was so big, and thus discarded it.

By this point, Zhu Yunwen already had a guess in his mind.
