Human Immortal Martial Arts: Starting from the Synthesis of Kung Fu

In this world, there are three ways to practice: Martial arts cultivates Qi and blood, soul cultivates the soul, and true cultivation involves eating Xia, eating Qi, and refining Qi to return to the true state. However, if one cultivates one's life without cultivating one's nature in the martial arts, and one cultivates one's nature without cultivating one's life in the soul path, both will not be able to live forever and will be regarded as inferior. Only the way of cultivation that cultivates both life and life and uses the inspiration of heaven and earth for one's own use can last for a long time, and it is also regarded by the world as the true road to heaven. Chen Xing traveled through time and space. He had no spiritual roots and was unable to practice cultivation. He could only practice Qi and Blood Martial Arts and became a mediocre martial artist with a difficult future. Fortunately, he has a cheat, a synthetic upgrade function panel from the game before time travel: Invest x3 of "Zhenwu Yuan Gong" to synthesize "Zhen Wu Yuan Gong (Extreme)"; invest x3 of "Zhen Wu Yuan Gong (Extreme)" to synthesize "Zhen Wu Yuan Gong (Extreme)"; Invest x3 of the Iron Back Bow to synthesize the Iron Back Strong Bow; invest x3 of the Iron Back Strong Bow to synthesize the Black Iron Divine Arm Bow; Put in x3 of multi-year life extension fruit, and you will get a hundred-year life extension fruit; if you put in x3 of hundred-year life extension fruit, you will get a thousand-year life extension fruit... A little martial artist will use this to embark on the path of immortality that can shake the heavens and the earth, and live forever!
