The Master of Xuandu and the Wan Xiang Immortal stood in the underground formation chamber, looking at the surrounding Tai Yi Escaping Armor Yin Yang Great Formation.
The dense runic scripts that had originally covered the room from front to back, left to right, and top to bottom, now left a large empty space in the center of the ceiling.
"What is this?" the Master of Xuandu asked Luo Yan with an inquiring look.
"I compressed and encrypted a portion of the original formation," Luo Yan replied calmly, "Although the formation set up by my master was perfect, it was somewhat cumbersome. After simplifying some of the standard but unnecessary runic scripts, we not only save space for adding new elements later but also significantly increase the security. At least it won't be easily mastered by someone who steals a few years of learning."
"This is an ancient formation technique," observed the Wan Xiang Immortal with admiration.
Luo Yan respectfully responded, "Yes."
