Douluo Dragon King: Xie Xie, Starting from Giving Up to Become Stronger

One day, he transmigrated into the body of Xie Xie, the young master of the Xie family in Donghai City during the era of the Legend of the Dragon King, and obtained the "Playing it Off is Invincible System." [You refused to join the Tang Sect, and obtained a million-year soul ring!][You refused Wu Changkong's request to attend class, and obtained adaptive evolution battle armor!][You refused Yun Ming and did not join Shrek Academy, and awakened the Dragon God bloodline!][You refused Yuanen Yehui's request to cultivate together, and obtained divine inheritance!]... While the rest of the class was struggling in the training room, Xie Xie's mental power received a massive boost! While others spent a fortune buying spiritual items, he slept in the dormitory and his combat power skyrocketed. Tang Wulin's three years of hard training were not as rewarding as Xie Xie's awakening of the space-time domain. When alien creatures from the abyss tore through the defenses, everyone realized that this seemingly lazy boy who attended class on time and rushed to the cafeteria after school had, unknowingly, become the only savior of this era.
