To Create a Pure Bamboo Douluo, Let's Work Harder for Tang San.

Zhu Shen woke up, traveled through time and became Master Yu Xiaogang, and was bound to the [Bamboo God Pit Three Systems]. Weird restriction of the system: All Tang San's soul rings must be Lone Bamboo, and his soul bones must also be Lone Bamboo. System special effect: You can also get generous rewards by tricking Tang San, but you can't be discovered by Tang San. "Tang San, do you think you are awesome? I am helping you behind your back." "Teacher, is my soul skill Blue Silver Pole Vault... Really possible?" "Don't worry, can I still harm you as a teacher?" "For our glorious future, we can only suffer a little hardship first." (The single female protagonist Bibi Dong is funny, deceitful, adds an evil organization, and has an internal cast)
