Duan Ling Tian had just returned to the Upper Province of Dao Martial Saint Land not too long ago. The first time he was in the Upper Province, he still did not know about the existence of Bodiless Celestials. When he received the message from Qing Huo, a Guardian from the Fire Worship Sect, it was not difficult for him to guess that the mysterious young man and his servant who was probably a Three Tribulation Bodiless Celestial were from the dragon clan. They had probably come because he had killed Li Bing.
Duan Ling Tian was not surprised that the people from the dragon clan knew he killed Li Bing since he noticed a Mirror Image Talisman had been activated when he killed Li Bing. The entire scene was probably transmitted to the other person who held the corresponding Mirror Image Talisman. The other person should be Li Bing's master.
