Slay demon beasts to gain spiritual energy and unlock martial skills. Breaking through realms comes as easily as drinking water. From a rookie at the early First Rank, he gradually grows into a pillar of humanity, standing against the myriad races.
At Qingyun Academy, he meets Su Qingyue, an aloof and otherworldly ice-element prodigy, and Lin Xiaowan, the eldest young lady of the Lin family, who excels at formations and talismans. His bond with the mysterious healer Ye Zihan also grows ever closer. Between classroom cultivation, deadly trials, and duels with geniuses, he repeatedly performs miracles with the System's help, but he also draws the jealousy of family scions and the covert attacks of a mole within the academy. Those who have allied themselves with the alien races while hiding among the cultivators are quietly opening the gates to invasion.
From the academy's trial grounds to the battlefield of the myriad races, from Rank One demon beasts to alien generals, Lin Chen wields his Green Edge Sword and leads his companions to slay demon beasts, foil conspiracies, and resist the alien races. The System's missions grow ever more difficult, and he repeatedly breaks through the limits of his cultivation. He must not only reach the pinnacle of the Nine-Rank Peak but also protect humanity's last place of survival and uncover the ultimate secret behind the spiritual qi revival.
This is a stirring legend about a young man who rises with the help of a System, fighting for humanity alongside the women he loves in a world surrounded by roaring demon beasts and hostile alien races.
