At this moment, Xin Yun's Four Great Sword Souls had crossed the golden bridge of the Tai Chi Diagram and arrived instantly within Fanghu Immortal Mountain. As it stands, with only one layer of the Tai Chi Diagram unsealed, it's still unable to transport very large objects. Fortunately, the Zhu Xian Four Souls are only the size of soda bottles, so it wasn't a problem.
This Tai Chi Diagram, relying on the principle of Yin-Yang transformation, can open a space channel. Back in the day, the Purple Dawn Palace, before Hong Jun started his lecture, used the Tai Chi Diagram to conjure the golden bridge, allowing listeners to go up and hear it. If it weren't for the protection of the golden bridge, with no saints present at that time, who could have reached the Purple Dawn Palace amidst the chaos?
