Invincible After My Spiritual Root Was Stolen

After his heavenly-grade golden spiritual root was secretly drained by an elder, Lin Mo spent eight years stuck at the third level of Qi Refining, becoming a laughingstock in the Qingyun Sect. His childhood friend, Su Qingyuan, is sharp-tongued but soft-hearted, scolding him as trash while secretly giving him foundation-building pills and using her cultivation to protect him, making him a target for others. In a desperate situation at the back mountain, Lin Mo drips blood to bind a rusty broken sword, awakening the dormant remnant soul of the Heavenly Sword Venerable. 'So what if your spiritual root was stolen? I'll teach you the Chaos Sword Bone Art, forge an unmatched sword body, and reaching the peak of the sword path is just the beginning!' With marrow cleansing and meridian rebuilding, he reforges his foundation. One sword breaks all techniques, and leaping realms is as easy as drinking water. He masters alchemy and formations with ease, invincible at the same level, and slays prodigies across levels. Those who once trampled and humiliated him fall to his blade, and the mastermind behind his stolen spiritual root will pay in blood. From a dark horse in the outer sect competition to a stunning presence in secret realm treasure hunts, he rises from sect trash to a sword supreme guarding his domain. Su Qingyuan, blushing, shoves high-grade talismans at him: 'Who, who's worried about you! I just don't want you to embarrass me!' Lin Mo smiles, holding his sword. He will reclaim what is his and protect those by his side. — Description from novelcodex.org
