Besides that, the most fatal factor is that a Cultivator Crossing the Tribulation cannot use summoning-type Treasures!
For example, Lin Xuankong's Seventh-Grade Buddha-Calling Jade Talisman... Sect Leader Li of the Spiritual Crane Immortal Sect obviously knew that Lin Xuankong possessed such a Jade Talisman that could summon a High-Grade Earth Immortal. However, the problem was that under the Celestial Tribulation, that kind of Jade Talisman was absolutely unusable!
Thinking of all this, a trace of despair rose in the heart of Sect Leader Li of the Spiritual Crane Immortal Sect. He watched as the Spiritual Crane Immortal Sect was continuously rising due to Tributor Mu. It had already achieved the status of the First Immortal Sect in the Central Divine Dynasty Western Region. Given time, becoming a large Immortal Sect of the Central Divine Dynasty was practically a certainty. Yet, now they were encountering such a situation... How could he not despair!
