Mao Shengjie first mentioned in the letter the gains from this trip to Feng Yongkang city.
The green crystal stone, called 'Cyan Wood Marrow Crystal,' is a spiritual object that can enhance the cultivation of cultivators practicing wood-element techniques and can also be used in artifact refining.
Neither he nor Dou Qianyu could use it, so he left it to Liou Yuan to sell, as he's not bothered to handle it himself.
Of the remaining spiritual objects, two were useful to himself, which he exchanged for two hundred Star Stones and gave them to Liou Yuan.
However, Mao Shengjie didn't mention what the remaining spiritual objects were in the letter and directly sent them as Star Stones, which made Liou Yuan's face darken halfway when he looked at the Star Stones in the black wooden box.
Given his understanding of Mao Shengjie's money-loving nature, eight out of ten chances, this fat man took a cut.
