Take the System to Dousan

What kind of sparks will be created when the spell encounters the system, encounters rebirth, and encounters the Douluo Continent? This book is purely fictitious and any similarity is purely coincidental. Note: All the couple combinations remain the same, there is only one heroine fabricated by me. There is no harem here, only brothers and the system. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
