The merits of traveling to the west to obtain Buddhist scriptures are complete, and the sound of the bells of Buddhism's eastward journey shakes the three worlds. In the name of "saving all sentient beings", Tathagata Buddha led thousands of Buddhas and Arhats to expand eastward and preach, and the foundation of Taoism was crumbling. Zhen Yuanzi, the ancestor of the former Earth Immortal, noticed that Buddhism wanted to use the power of cause and effect to erode the destiny of the Central Plains. Wuzhuang Temple in Wanshou Mountain, as a sacred place for Taoism, was the first to bear the brunt and became the forefront of the confrontation between Buddhism and Taoism.
An accident caused Zhang Cong's soul to travel through the three realms and possess the thousand-year-old mulberry tree in Wanshou Mountain. The ancient tree burst out with spiritual light due to him and turned into a human form. Zhen Yuanzi was attracted by this vision and accepted him as a closed disciple. As a stump of the hibiscus tree with innate spiritual roots, Zhang Cong started a unique path to immortality with his memories and insights from his previous life.
The concepts of Buddhism and Taoism are in conflict with each other, and there are turbulent undercurrents beneath the surface of peace. The venerable Tathagata frequently exerted pressure in an attempt to expand the power of Buddhism. Wuzhuangguan was involved in the fierce collision between Buddha's light and Taoism, and Zhen Yuanzi and his disciples were in deep crisis. Zhang Cong relied on the wisdom in his past life memories to deal with immortals and Buddhas, turning his knowledge across time and space into a strategy to break the situation. He cleverly dealt with the temptations of Buddhism, and used strategies that were not of this world to build a line of defense for Wuzhuang Temple on the battlefield where the rhyme of Taoism and the light of Buddha intertwined. Facing the menacing Buddhist forces, can Zhang Cong, the "Sang Ling" with memories of another world, protect the dignity of his mentor and preserve the peace of Wuzhuang Temple? This chess game between Buddhism and Taoism has quietly changed because of his presence.
