Such a vast and immense project undeniably posed a colossal challenge for Lin Feng. Unlike the other three Spirit Array Masters, they only needed to bury the Array Formation Materials within the Array Eyes set up by Lin Feng, and then apply a simple Illusion Technique to conceal those Array Eyes. But Lin Feng had to inscribe line after line of Spiritual Patterns, using the fresh blood of the Flame Beast as Talisman Liquid. The fresh blood of the Flame Beast could solidify rapidly, and once transformed into Talisman Liquid, it would last for a long time without dissipating. The Spiritual Patterns would also exist for a long period, unlike those made from the blood of other Spiritual Beasts, which might start to fade after a short while.
