Li Feng drew everyone's attention, while Lin Chen and Feng Jiu arrived at the stone door.
There was a keyhole on the stone door.
Seeing the color of the keyhole, Lin Chen felt a surge of joy in his heart.
The keyhole was blue.
This meant that the stone door could be opened with the blue key.
Lin Chen took out the blue key and inserted it into the keyhole.
Accompanied by a dull noise from the stone door, it slowly opened.
Upon entering the stone chamber, Lin Chen discovered a small emerald-green herb growing inside.
The herb looked no different than ordinary grass, but green energy emanated from around it, giving off a pleasant scent.
"Little Handsome, what kind of grass is this?" Lin Chen asked.
"This grass is called Spirit Source Grass. No matter how grievous the injuries, consuming this herb can bring one back to life."
"Oh, it truly is something precious." Lin Chen nodded.
