The problem Pei Yuzheng wanted to raise was that Cang Lin had added things beyond the foundational level into the ninth Starry Diagram.
For young army formation masters, that was naturally a huge problem—it was deliberately making things difficult for whoever tried to solve it.
But if it was all foundational Army-Slaying Formations, then if he failed, he could blame no one.
Young army formation masters were supposed to learn the fundamentals. If they could not solve something foundational, it simply meant they were weak. There was no other excuse.
That was why Cang Lin had stated it so openly...
At the same time, Tie Binghun and the others, who had just been stunned, suddenly brightened and immediately understood Cang Lin's intention.
Yet Pei Yuzheng refused to believe it. Staring fixedly at Cang Lin, he said, "Impossible. There must be something beyond the foundational level inside."
Among all his brothers and sisters, his foundation in Army-Slaying Formations was the most solid. The Thousand Kings Holy Tower's strongest army formation master had said that as long as he came to Ancient City, he would be able to crack Cang Lin's Starry Diagrams with ease.
The Thousand Kings Holy Tower's strongest army formation master also knew Cang Lin's attainments in Army-Slaying Formations inside out.
It was not as though a top-tier army formation master could create an unsolvable foundational puzzle. The nine Starry Diagrams were already Cang Lin's limit within the fundamentals, so Pei Yuzheng was certain to win.
That was why he believed there had to be something else within them.
But then... hahahaha!
Cang Lin answered Pei Yuzheng with a booming laugh, his white beard and hair flying wildly.
"The ninth Starry Diagram is right here. You may take it to any army formation master and have them inspect it."
