Indeed, to put it simply, there are ten layers of arrays here.
The very bottom layer is indeed based on the Divine Teaching's Ten Extremes Earth Sinking Array that Eastern Venerable set up in Suiyang back then. The framework of the Divine Teaching's Ten Absolute Array allows for ten arrays to be stacked, thereby multiplying the power.
And just Tie Dan's Sword Casting Array alone uses three layers of array bases. The second layer employs the secret technique of the Kaiyang Sword Formation, drinks from the sweet spring, flows with the eternal wind, and illuminates the jade candle, transforming the power of the array into a refining sword melting furnace. The third layer uses the YCM Reincarnation Technique, trapping the blood souls of heroes from the battle in Suiyang within the array for sword quenching. The last time, it only quenched for a month before attracting the attention of the Five Elders. This time, it has quenched for a full ten years, shocking both Heaven and Earth.
