The three heaven-breaking maps can realize the location of the Reverse Yang Wonderland and the pass to enter the Reverse Yang Wonderland, and the Reverse Yang Immortal Emperor is known as the Immortal Emperor with the highest treasure in the Immortal Demon Realm, so there must be many treasures in his mansion after he fell. Therefore, even the powerful people of the Immortal Demon Realm were very interested in the treasures in the Reverse Yang Immortal Realm, so they all sent emissaries to snatch the treasures.
The Immortal Realm sent a first-level Golden Immortal - Hua Yan, the Demon Realm was a first-level Demon King - Du Zhongjun, and the Demon Realm was a first-level Demon King - Barbarian Qian
These people are basically the elites of the Immortal Demon Realm, which shows the importance that the rulers of the Immortal Demon Realm attach to the Reverse Yang Immortal Realm. Their goal was not only to obtain several artifacts in the Reverse Yang Immortal Palace. And their ultimate goal is the 'Ecstasy Scroll'. So what exactly is this 'Ecstasy Scroll'?
In the Immortal Demon Realm, there was a 'Lost God Temple' that had fallen from the Divine Realm, and the lord of this Mythical God Temple was originally an upper Heavenly God-level alchemist in the Divine Realm, and many God Kings would look for him to refine artifacts, which showed the strength of this temple lord. Therefore, there are many treasures in the Temple of Ecstasy. Without this map, even the people of the Ninth Rank Demon Emperor could not enter the Lost God Temple, so the people of the Immortal Demon Realm wanted to enter the Reverse Yang Immortal Realm to grab this map 'Lost God Scroll', because with it it was equivalent to hundreds or even thousands of artifacts, because the artifact could make the strong person far stronger than the monks of the same rank, it was conceivable that this was the purpose of everyone who wanted to enter the Reverse Yang Wonderland.
