The time traveler Qingwu accidentally landed in a different world with "Ya" as its core origin. When all creatures are born, the veins of heaven and earth will merge and converge, and a special bud base will be condensed deep in the heart. However, it is impossible to practice with only the bud base. You must step into the natural secret realm of light and absorb the energy of the sun to nourish it, so that the bud base can produce leaves and officially embark on the path of cultivation. The leaves are divided into four stages: Chuze, Maize, Yaoze, and Daquan. When each leaf reaches the Daquan state, it can break through the first level of cultivation. A monk can breed up to fifteen leaves, corresponding to the realm of one to fifteen rivers: one to seven rivers is a pulse guest, and eight to fifteen rivers are advanced to a pulse observer. The color and shape of Yaji determines the talent for cultivation. The red sword shape is more suitable for fire swordsmanship, the black furnace shape is good at dark element forging, and the transparent Yaji is the most heaven-defying and can resonate with all attributes. The special treasure called "pattern" is the key to the competition between the strong. The first to seventh grades are vein patterns, and the eighth to fifteenth grades are rare patterns, with only one or two left in the world. Patterns can be attached to the leaves, and only one per leaf is allowed. Wild patterns will be lodged on the surface of the bud beast with corresponding cultivation level. To activate the patterns, physical strength, mental energy or vitality must be converted into dazzling energy. This continent has distinct boundaries: bounded by vast grasslands to the east, endless deserts to the north, lush jungles to the west, and vast oceans to the south, with a snow-capped mountain basin standing in the center. The skies in the five regions have different colors and different circadian rhythms. The cruel thing is that advancing one's cultivation level cannot extend one's lifespan. Only the naturally born source of light energy can continuously produce the cultivation currency Yingjing, which has become the lifeblood of competition between all parties. The protagonist Qingwu is about to find a way to the top in this world of life and death.
