Depressed Purity

Su Mo, a young man of the modern times, transmigrated to the world of martial arts. The sole survivor of the declining Su family, he inherited the Purple Sun Escort Company, a courier service that was on the brink of collapse. Su Mo was determined to restore the family business to its former glory, but he was young and inexperienced. And the martial arts world was fraught with dangers and intrigues! 
Unexpectedly, a system popped up that rewarded him each time he completed a courier mission. With this reward system, Su Mo entered an unprecedented realm. He mastered the Dragon Elephant Wisdom Technique which transformed his internal Qi and gave him boundless energy and stamina to accomplish his missions. 
Still, troubles came knocking on his door as he embarked on his missions, from escorting a benign scholar to delivering a mysterious brocade box for a dying man. Could Su Mo avoid getting tangled in other people's affairs? And would he survive the storms and gain a foothold in the treacherous martial arts world?

I Got A Maxed Level Divine Technique From The Beginning

Actually, Yang Xiaoyun already had an answer when she asked this question.

Without waiting for Su Mo to speak, she said, "I heard something."

"Wei Ruhan actually doesn't want to give the position of the chief leader to anyone."

Yang Xiaoyun continued. "Wei Ruhan originally had three sons. The eldest son, Wei Qifeng, fought with someone on the banks of the Cross River. He was killed and thrown into the Cross River. Wei Ruhan led his men to search for him for three years, but they could not find his corpse."

"The second son, Wei Qixiong, has been apprenticed to the Yin Yang Stranger since he was young. In order to cultivate the Heaven and Earth Great Millstone Yin Yang Disc, he stepped into the extreme north alone and went deep into the glacier for 10,000 miles. This trip lasted for 23 years and he had yet to return… I'm afraid everything pointed to disaster."
