There were many types of Celestial Supreme Treasures. For example, the Jasper Celestial Sword on the second floor of the Seven Treasures Exquisite Pagoda was an offensive-type Celestial Supreme Treasure. On the other hand, the Astonishing God Halberd on the third floor of the Seven Treasures Exquisite Pagoda was an offensive and defensive-type of Celestial Supreme Treasure. The Universe Ruler on the fourth floor of Seven Treasures Exquisite Pagoda was an assist-type Celestial Supreme Treasure that could be used to confuse one's opponent with its unique divine ability, the Universal Teleportation.
With Duan Ling Tian's current strength, he possessed only the barest of strength to use the Universe Ruler. For this reason, when he cast the Universal Teleportation, the effect was very weak.
