544. There are too many water caltrops_1

9:00, we had to head back, it wasn't that Song Tan couldn't handle the hardship, but the summer sun was just too scorching.

Moreover, considering Professor Song's level of dedication, there was no chance they would simply head back in such a carefree manner.

For instance, at this moment, although Professor Song had closed his tablet, he pointed towards the high ground of the small mound ahead, "Just perfect, let's check that place on our way back."

"Yan Ran, I remember you put your hoe there, right? Go dig it up and see if the soil underneath is moist."

They definitely didn't carry their tools everywhere they went, but instead made a mark on the chosen spot to dig and take a look on the way back.

This statement... Song Tan thought: If it weren't for your thorough sun protection gear, I would have thought you really weren't afraid of heatstroke!

In this weather, her dad wouldn't dare to exert himself under the sun!
