The Black Tortoise Kingdom's Guardian Black Tortoise: Official History or Unofficial History?

As the saying went, nothing was hard for those who knew how. Once they had the right method, water veins, which seemed rather mysterious, were not actually difficult to detect.

It was merely somewhat tedious and required going there in person to confirm.

Li Yingling was currently taking Li Xingtian along to explore the water veins near Chizhou.

Li Yingling handled the detection, while Li Xingtian handled the recording.

Once Li Xingtian finished recording, he showed it to Li Yingling for comparison to see whether anything was wrong.

It was not that Li Yingling insisted on ordering her junior brother around, but if she drew it herself...

Li Xingtian would have some trouble understanding it, or rather, reading it would be a real struggle-the way Li Yingling marked things was rather similar to the notation in the Commentary on the Water Classic.

Li Yingling used her markings to skip straight over places without water veins.

Naturally, Li Yingling felt her method was clearer and easier to understand. Not having to draw the entire river system improved efficiency considerably.

However, there were simply too many places without water veins.

If Li Yingling really drew it, that vast map would contain only a few sparse strokes.

If Li Xingtian took a map marked by Li Yingling and went back to identify the water veins, he would probably have a hard time recognizing them.

Besides, before they left, Chu Xingchen had specifically instructed them to keep it simple and easy to understand.

So having Li Xingtian draw a detailed map of the water veins was the best solution.

But along the entire great river, tributaries extended in all directions, and most had no water veins, or only faint ones that seemed barely there.

Li Xingtian's method of drawing everything naturally slowed their progress
