As for the materials needed to construct the Eighth Order Formation, he actually intended to obtain them from the Flying Crane Secret Realm.
It should be noted that so far, he had only explored the periphery and the middle layer of the Flying Crane Secret Realm.
As for the core area, he had not yet entered.
Furthermore, the Flying Crane Secret Realm was originally the main headquarters of the Flying Crane Clan.
Their downfall occurred too swiftly, perhaps leaving behind a wealth of treasures and materials.
Perhaps within the core area, he could directly find the materials for the Eighth Order Formation.
Of course, even if he couldn't find them, he could still use the power of the Object-searching Gu to search.
In any case, he felt that constructing the Eighth Order Formation in the future should not be a big problem.
"I also obtained twenty top-grade Tongtian Spiritual Treasures in the form of flying swords."
