Magic coffin. Belonging to Min and Zhang Sanfeng, the shell of Xuan Coffin is indestructible, fireproof and waterproof, and even not afraid of volcanic lava. The mysterious coffin is a wonderful space. This fantasy space is not only an excellent place to practice martial arts, but also an excellent treasure house of magical powers. Wen Tianxiang kept Tian Zi's martial arts in it. It was in it that Emperor Song Ming developed the innate skills of Gangong Kun and Tathagata Palm, and it was in it that Temujin Canglang broke through the divine power of blood, and it was in it that Zhu Yuanzhang developed the highest realm of Shen Ming's code of harness. Zhang Sanfeng and Min are considered to be the strongest people in Tian6 at present.
