The Immortals of the Upper Realm Made Me Their Blood Food, So I Blew Up Their Realm

[No female lead, invincible protagonist, powerful expert, nurturing geniuses] Yi Jiangnan transmigrated to the Tianling Continent and broke through to the Great Emperor Realm in just two hundred years, then began his ascension. However, after ascending, Yi Jiangnan discovered that the Tianling Continent was merely a “pigpen” for the immortals of the Upper Realm. Every ascendant was captured and turned into ingredients for the immortals to refine elixirs. Unwilling to submit, Yi Jiangnan fought to the death against two immortals of the Upper Realm, then decisively blew himself up. At the crucial moment, the System he had waited so long for finally arrived, bringing Yi Jiangnan back to the Tianling Continent a hundred thousand years later. From the System, Yi Jiangnan obtained half of the supreme immortal artifact, the Creation Immortal Disc, and began cultivating the Creation Divine Art. Following the System's guidance, Yi Jiangnan founded Jiangnan Academy and became a teacher. While educating his students, he also set about creating a new, complete Creation Immortal Disc. Under his tutelage, one extraordinarily gifted student after another emerged from Jiangnan Academy. Chi Yuan: The teacher said never to give your enemies a chance to fight back. One-shot kills are best. Gu Xiting: The teacher said only the weak complain about their circumstances, while the dead can only lie there stiff as a board. Meng Zhiyi: The teacher said truth only exists when your fists are hard enough. Shi Qingqian: ... Years later, outside Jiangnan Academy, one powerful figure after another, each surpassing the Great Emperor Realm, knelt in reverence and shouted in unison: “We respectfully beg our teacher to emerge and lead us in storming the Upper Realm!” Yi Jiangnan walked out slowly and said calmly, “It's about time we blew up the Upper Realm!”
