Douluo: Five Thunder Drum, Starting with Sacrificing Gangzi

Yu Tianchen transmigrated into the Douluo Continent, becoming the grandson of Yu Yuanzhen, the patriarch of the Blue Lightning Tyrant Dragon Clan. He awakened a mutated martial soul, the Five Thunder Drum, with innate full soul power, making him the most dazzling prodigy of the younger generation in the sect. Just then, the system that had been dormant since his transmigration activated! By binding a sacrifice and performing a sacrifice, the greater the gap in talent or cultivation, the greater the benefits! After learning the system's function, a figure immediately appeared in Yu Tianchen's mind: his second uncle, Yu Xiaogang! In terms of talent, there was an absolute gap between them! No choice, Gangzi, for the sake of becoming stronger, I can only make you suffer a bit. [Sacrifice successful! Yu Xiaogang's soul power level permanently reduced by 5, misfortune increased threefold, duration one year] [Congratulations, host, you have received the offering: Great Sun Thunder Body] [Sacrifice successful! Yu Xiaogang's soul power level permanently reduced by 3, enters temporary kidney deficiency state, duration three years] [Congratulations, host, you have received the offering: Eight Gates Resonance Method] [...] As Yu Tianchen performed a sacrifice every ten levels, Yu Xiaogang's nightmare of a life began. Just after joining Notting College, his soul power inexplicably dropped by 5 levels, and he even knocked out his own front teeth. Going out, his soul power dropped by another 3 levels, and his steps faltered, causing him to intimately kiss an indescribable object by the roadside. Taking on Tang San as a disciple, he only dragged Tang San into suffering with him. Years later, when Yu Tianchen held the inheritance of the God of Destruction and ascended to the highest realm with a group of beauties. [You have obtained an ultimate sacrifice opportunity, rewards doubled!] Rewards doubled?! Yu Tianchen's eyes lit up. In that case, I can only make you suffer a bit more, Gangzi!
