Sun Zhe suddenly remembered a record in his grandfather's medical book. According to the description, Earth Heart Grass usually grew near tombs.
This plant was also known as the "Passage to the Nine Netherworld" because its roots grew exceptionally deep, as if connecting to the underworld itself, hence the name. In ancient times, powerful figures would often plant this grass around their tombs. Not only did it reinforce the soil to prevent grave robbers from digging, but it also symbolized a passage to the netherworld.
If there was anywhere Sun Zhe could find Su Nanzhi now, it had to be the ancient tomb the Chen siblings had mentioned. It was the only and closest clue he had.
Nanzhi, I hope you're safe. No matter where you are, I will find you.
A short while later, the Chen siblings found clean clothes in their backpacks and changed. After tidying up, the three of them prepared to set off.
