The teaching building was extremely chaotic now. Many students were running around.
"Did something happen?"
Someone asked.
"Quickly go and take a look. Teacher Sun is challenging the unlimited challenge mode again. If we miss out on it, we might not be able to see it again."
The students who heard this couldn't even be bothered to keep their books and immediately sprinted toward the Dragon Subduing palace.
"Helian, I still have a presumptuous request!"
"Tuoba, help me teach a class. I will pay you ten spirit stones."
The two dorm mates of Sun Mo ate breakfast together and came here. After knowing the reason for the commotion, they glanced at each other and spoke out at the same time.
"Helian, I will pay 15 spirit stones."
Tuoba gritted his teeth and gave a sky-high price.
"Do you think I'm someone that lacks spirit stones?"
