I Have Been Guilty for Seven Years, and the World's Bosses Are Begging to Be My Dog.

[Seven years of guilt + no system + revenge + master released from prison + almighty + invincible] Seven years ago, in order to repay the "life-saving grace", I was imprisoned for the crime of a wealthy young man, and was imprisoned in the "Dragon Prison" where thousands of the world's top criminals gathered. In seven years, I worshiped thousands of masters, learned thousands of Dharma, and became an unparalleled fierce god! Seven years later, I was gloriously released from prison, but my former benefactor hugged my fiancée and told me the truth about how he destroyed my whole family back then! He even tortured my true benefactor, the girl who sacrificed her life to save me, to a point where life was worse than death! At that moment, the evil god returned, and the sea of ​​​​blood surged into the sky! I, Xiao Fan, swear to God that I will make all my enemies kneel and go to hell in endless regret and fear!
