Following the gangue layer downward, they went about several hundred zhang.
A crisp "bang" suddenly rang out below, and something had actually blocked Yu Taibai's path.
"We've reached the Flint Layer. Shall we keep digging downward?" Yu Taibai asked.
The Flint Layer consisted of semitransparent stone crystals, and it was a hundred times harder than the gangue layer!
Of course, no matter how hard the Flint Layer was, it could not possibly stop Yu Taibai.
"Wait. Something seems wrong with our direction," Luo Zheng said with a frown.
The last time he had escaped underground, his World Within had immediately reacted.
That brown lump of mud—namely, the Spirit Crow—had radiated an intense attraction toward Luo Zheng.
Yet this time, after going so deep underground, Luo Zheng's World Within still had not reacted in the slightest. This showed that they had deviated from their path!
Come to think of it, Luo Zheng had clearly dug downward from in front of the Tie Family's house the last time, and he had ultimately escaped from above that cavern. In the end, it had led to the pond in the Tie Family's backyard.
Luo Zheng had reached the conclusion then that the underground caverns could move freely.
However, his mother had asked him to go to the Six Ren Domain to find her, so there definitely should not be a problem here.
"Over there." Luo Zheng could only rely on his instincts now.
Yu Taibai nodded. He did not lead Luo Zheng through the Flint Layer. Instead, he moved sideways through the gangue layer.
But after traversing sideways for quite some distance, Luo Zheng's World Within still showed no reaction at all, and they ultimately had no choice but to stop...
"Could Master's Wife have left this place?" Yu Taibai asked with a frown.
