From the Start in Snow: Sign-In for the Heaven-Swallowing Art, I Am Xu Xiao's Eldest Son

Tianlin is transmigrated as Xu Xiao, the King of Beiliang’s illegitimate son, kept hidden from the world and treated with contempt. At sixteen, his martial arts sign-in System awakens, granting him the peerless art Devouring Heaven and Creation from the start! On the night he is acknowledged by the Beiliang royal household, experts from the Liyang royal family slaughter everyone there. He transforms into a demon of slaughter and devours his powerful foes. Xu Xiao’s tiger eyes brim with tears. “My son! Today, your mother’s blood feud will be avenged!” Xu Fengnian hands him the Beiliang saber. “Big brother, you should be the heir!” Once he leaves the palace, every sign-in makes him stronger: he overwhelms Xuanyuan Dapan with his sword at Snowy Flat, then shatters Wang Xianzhi with his saber in Wudi City! The Liyang emperor trembles. “The plot against the princess consort back then… it was the will of the Celestial Realm!” Surrounded by beauties of the martial world, with a demoness from the demonic sect warming his bed and a fallen princess taking arrows for him, Xu Tianlin sneers. “This world isn’t worthy of a single drop of my mother’s blood.” Then envoys from the Celestial Realm descend, intent on destroying the mortal world. He devours all the immortals and Buddhas in the sky, and the System booms: 【Ultimate sign-in complete. Welcome the new Heavenly Order!】 Wherever the Beiliang cavalry rides, the laws of Heaven follow!
