Long Ming was initially conflicted when he chose Lin Xie, Chen Yin, and Shui Huan for the Purple Crystal Pavilion's Core Zone.
The reason he didn't choose Luo Yingying was because she was proficient in the dao of rune inscription. There would be many other chances for her.
However, These three got the better fighting force among the other disciples. Giving them opportunities is the same as increasing the power of Four Seasons Valley.
When Liu Jiang replied that the division of zones just dived the pressure from the stone wall, Long Ming was relieved. That meant that it will only increase the delay of someone's immersion in the stone wall. Other than that, one can still comprehend the dao rhythm of the stone wall from the Outer Zone.
And the thing Long Ming least worried about was comprehension. When he saw all three disciples of Four Seasons Valley get adjusted to the pressure of the Core Zone, he sighed in relief.
" Alright, I should start now."
