Tian Shan Ye gave him two jade tags.
One of them contained his entire life's worth of sword and blade techniques.
The other was a jade tag he picked off the ground to record his understanding of the realm demon.
Gu Qing Shan caught the first one.
This jade tag was shining and glittering, obviously nurtured for countless years.
Jade tags are originally a milky pure white color, only the ones that contain particularly valuable information are kept by the cultivators' side for them to check and use at their convenience.
During this process, the cultivator's spirit energy will unconsciously flow into the jade tag, slowly increasing its quality throughout the years.
This was a very common occurrence in the cultivation world.
That was also why most people would feel curious about what information a particularly high-quality jade tag contains.
Gu Qing Shan was holding the tag quite tightly in his hand.
