Staring at Old Gao, Di Tou waited to see if there was anything else he had to say, and seeing that Old Gao seemed finished, Di Tou even went the extra mile and asked again, "Is there anything else I should know about or should be cautious for?"
Blinking, Old Gao scratched his chin and shook his head. "Just go in and select a material. It won't be hard." After pausing for a moment, Old Gao smacked his head and said, "Ah! Actually, if the seal is red, it means that it's missing some information or is outdated in the current era, while if it's blue, it's complete and currently in circulation. Anything between that is just a mix"
Seeing this, Di Tou couldn't help but let out a sigh. Where had the charismatic and talkative Old Gao from years past gone? You had to know, Old Gao had once been a breakfast salesman, although he wouldn't talk your ear off, he could at least make a d*mn good sales pitch!
