When Shen Ming, a doctor of traditional Chinese medicine, died while saving a child in a car accident, when he opened his eyes again, he was in a green brick market suspended in the chaotic void - this is the "City of Ten Thousand Boundaries" that connects thousands of worlds, and the birthmark of the bronze door knocker on his wrist is the key to controlling causal transactions. The Shennong inheritance given by the system can refine the strange fire of "Fights Break the Sphere" and the unicorn blood of "Wind and Cloud". The book of cause and effect can provide insights into "cracks in fate" such as Li Yunlong's brain injury and Xiao Feng's life experience.
As a level 1 small city lord, Shen Ming welcomed Zhao Gang from the "Bright Sword" world when he opened the door for the first time. The political commissar covered in gunpowder used seven bloody Japanese gold bars in exchange for the "Resurrection Pill" that could repair Li Yunlong's brain damage. When the Shennong Cauldron was refining the medicinal materials, the afterimage of the independent cavalry company's charge appeared in the cauldron - it turned out that every transaction was weaving a new thread of cause and effect. From Tong Xiangyu's exoneration gold medal in exchange for a time-travel charm in "Wulin Gaiden" to Wu Xie's Warring States silk books in exchange for insect repellent powder in "Tomb Robbers", there is salvation across dimensions hidden under the blue brick house: Bai Zhantang's sunflower acupuncture hand collided with the fighting skills of the special forces in the martial arts field, and Gray Wolf's sheep-grabbing shovel unexpectedly dug up meteorite copper in "Old Nine Gates".
As the causal value accumulates, the City of Ten Thousand Realms has been upgraded from a blue brick market to a Tiandao-level fortress, and the connected world has also climbed from a low-level city to a prehistoric myth. Shen Ming gradually discovered that the earth where the spiritual energy of the main world was revived was actually the "Laboratory of Heaven", and the city pattern on his palm was the fulcrum that moved the gears of destiny. When the lightsaber of "Star Wars" resonates with the particle cannon of "Gundam" at the Civilization Expo, and when Lin Daiyu's poetry club opens in the metaverse, he must wander around as a "half-saint"
