This time, everyone decided not to let Zhuang Zhuang dig through the mountain tunnel again. The Earth's Curse isn't something that, once you've broken it once, you can necessarily break it a second time.
This sort of curse from the Earth is at best a warning the first time. If you recklessly try to breach it again, it's going to come at you in earnest, so the option of digging a tunnel is absolutely off the table.
Ye Lingyun wasn't one to dawdle. Seeing that this path was blocked, she immediately said to Zhan Yun, "Since that's the case, let's wait three days. After three days, I will help you unlock the third chapter! Then, we will make our breakout together."
Zhan Yun nodded slightly: "Good!"
Time flew by, and after three days, the crystal skull was finally ready to unlock the third chapter.
