Zhuge Liang became curious and inevitably asked Zhou Yu for more questions on the Yizhou map, wanting to understand the customs and customs.

However, just as a group of people talked and discussed, Zhuge Liang realized a problem: Although Zhou Yu’s map was not accurately drawn, the shape of the island was tilted.

However, there are quite a few marked islands, and the location distribution is also very finely drawn. At least seven or eight groups of small islands around Yizhou have been marked.

Zhuge Liang didn't know where these islands were, and Li Su had read the map of later generations. After being reminded by Zhuge Liang, his inner surprise was even more serious than Zhuge Liang.

Because he found that from Penghu to Luyu Lanyu, Maodao Bird Island, even the Chi/Huangwei Island in later generations, and even some islands at the southwest end of Liuqiu were clearly marked by Zhou Yu.

This shows that although Zhou Yu has not had strong ability to draw and measure over the past five years, he has not weak ability to find islands in the vast ocean. At least he has discovered all the islands he should have. Even if the location and shape are drawn a little wrongly, the quantity is not missed.

"Where did Zhou Yu learn this skill? It seems that it is necessary to dig deeper. It's impossible. Where did he get the channels of modern navigation and geological technology?"

Even Li Su was puzzled.

However, he was already in a high position. If you want to know some inside information, there is no need to hide it. He asked him directly when he thought about it.

As long as Zhou Yu still wants to make contributions to the country and leave his reputation in history, he cannot hide it from him.

Li Su asked straightforwardly: "In just a few years, I have explored all the islands around Yizhou, and many small islands look only a few dozen miles in a radius. In the vast sea, I have never missed an island within ten miles. Could it be that I used some strange and wonderful methods?"

Zhou Yu was slightly surprised after hearing this question: It seems that the Prime Minister really knows what he knows and knows everything, and even knows about the technical difficulties in all aspects of the navigation field.
