Chapter 491 Seems A Little Difficult
"Then let's go, anyway, we're just running for a while." Tong Anian shrugged.

Jin Yi and Tong Annian were still riding Xiaoxue, while Gao Xuan and Han Lang rode behind them.

There is no village behind, only mountains and forests, but there are also some small rivers. Tong Annian kept drawing all the way, until he reached a wide river.

"The drawing is finished." Tong An Nian looked down at the topographic map in his hand, Han Lang walked over and looked at the blueprint in Tong An Nian's hand.

The picture above made him a little confused, so he could only look at Tong Annian.

"What does this mean?" Han Lang pointed to the circles on the topographic map and asked Tong Annian.Tong Annian looked over, looking at where Han Lang pointed.

"Do you remember that we passed by the woods just now? This place means the woods, and this is the river." Tong Annian explained to Han Lang one by one.

Tong Annian didn't explain too much. In fact, it's not exactly a topographic map. It can only be said that it looks similar, but it almost shows that Tong Annian needs mountains, rivers and altitudes.

However, in order to complete the large-scale project of repairing canals and diverting water, we still need to record the terrain.

"Is it finished?" Gao Xuan looked at Tong An Nian and asked, Tong An Nian nodded, Gao Xuan heaved a sigh of relief, and walked back with Tong An Nian.

On the way back, Tong Annian checked the map again, and she was relieved after confirming that there was no problem.

Back at the gathering place, Qu Zishi and the others had already arrived. Seeing Tong An Nian coming back, she hurriedly gave the drawn picture to Tong An Nian. Looking at the pictures drawn by Tong Annian, and then looking at the pictures drawn by myself, it seems to be completely different!

"An Nian, what's the situation? Why are the maps drawn by the two of us different?" Qu Zi looked up at Tong An Nian in puzzlement.

"You drew a map of the place we passed by, but I drew a topographic map, of course it's different." Tong Anian smiled at Qu Zi, but Qu Zi really didn't quite understand what it meant.

Gao Xuan asked people to prepare tables and chairs, and lit the lamps. Tong Annian put together the map drawn by Qu Zishi and the topographic map she drew, and planned to explain the use of the topographic map to Qu Zishi.

"The topographical drawing is about the undulations of the ground and the position and shape of the features on the horizontal plane. Just like here, you will directly draw high mountains on your drawing, but although there are no high mountains on my topographic map, you can. You can see the shape of the mountain at a glance, look."

"So that's the case, An Nian, can you teach me to draw this topographic map?" Qu Zishi looked at the topographic map drawn by Tong An Nian, although he couldn't understand it at first, but after Tong An Nian explained it clearly to him, he actually felt This topographic map is sometimes even more useful than a map, so it is natural to learn it.

"Okay." Tong Annian taught Qu Zishi how to draw a topographic map while preparing to draw a topographic map of the map they drew.

After half of the drawing, Tong Annian asked Qu Zi to draw the rest. Although the real song was still a little unsure, with Tong An Nian's help, he still drew the rest of the terrain.

"This one seems a bit difficult." Tong An Nian smiled as he wiped the sweat from his forehead after finishing the melody.

By the time they finished painting, it was already dark, so Gao Xuan and the others lit up the lanterns.

"Let's eat first, and we'll talk about other things after eating." Jin Yi walked over, rubbed Tong An Nian's head, Tong An Nian turned around and smiled at him, got up and stretched comfortably.

The topographical map has been drawn, and the map is already in her mind. After returning home, she is going to make a big sand table to test her ideas first. If it works, she can start working directly.
