Challenge the Impossible, Start from Reaching the Sky for a Hundred Days

Su Yu traveled to a world where spiritual energy was revived. Both his parents were dead and he had a blood feud. He started in hell mode. Fortunately, it was bound to the impossible challenge system, so I chose the Hundred Days Breakthrough Challenge at the beginning. Challenge nine levels in one day, and you will be rewarded with a nine-level golden body after completing it! Challenge eight levels in three days, and complete the reward as the Nine Dragons Sacred Tendon! Challenge seven levels in five days, and you will be rewarded with original essence and blood after completing it! Challenge six levels in seven days, and complete the reward to get the Supreme Bone of the whole body... Su Yu created impossible miracles one after another, shocking the whole world! On the 100th day, Su Yu broke through the first-level Heaven-reaching realm, broke the seal with his Tribulation Thunder Fist, and stepped into the outer world! Human Ancestor: "Impossible!" Demon Ancestor: "How is it possible?" Heavenly Spirit: "This is impossible!" Su Yu: "I, Su Yu, challenge the impossible!"
