The Douluo System Master: Giving Tang San a System from the Start

Li Ping'an woke up one day to find himself transmigrated into the Douluo Continent, becoming a nameless extra with no innate soul power. Fortunately, he discovered he possessed the Source of Systems, allowing him to grant subsystems to those with strong fortune and skim rewards from them. The stronger the subsystem user's fortune, the more Li Ping'an could skim. The kind-hearted Li Ping'an immediately gave the protagonist Tang San a system, making Tang San work for him.

Tang San: "Why do I have a system, yet I still can't compare to Li Ping'an?"

Yu Xiaogang: "The Evil-Slaying Sword Manual from the system is truly powerful—I actually broke through the twenty-ninth level bottleneck!"

Ning Rongrong: "I'm only doing this to complete the system quest. It's definitely not because I like Li Ping'an!"

Zhu Zhuqing: "Dai Mubai, stop bothering me. I'm afraid Ping'an will misunderstand!"

...Years later, Li Ping'an found more and more girls around him and realized something was wrong. "System, what subsystems did you give them?"
