Fantasy: Start Practicing from a Centenarian Old Man

When Su Yan woke up, he found that he had traveled to a world where spiritual energy was revived, and had taken away the body of a hundred-year-old man. The old man's vitality and blood were declining. Faced with Tian Jue's start, he was bound to a sign-in system, and he signed in every day to get rewards. "Ding, congratulations to the host for successfully checking in and getting the youth potion." "Ding, congratulations to the host for successfully signing in and receiving the eight-nine Xuan Gong skill reward." "Ding, congratulations to the host for successfully signing in and gaining immortality from the ten thousand acres of spiritual spring." It was originally Tianjue's start. After obtaining the system, he signed all the way to counterattack, formed his own force, expelled all races, killed the Martial Emperor, and achieved the supreme martial arts.
