The defensive city wall was roughly 500 miles long, and Chen Jiuge divided it into five segments, using numbers one through five for distinction.
Excluding Contracted Spirit Beasts, there were only 11 True Immortal-level Spiritual Beasts, which worked out to two per segment. There was no shortage of Mahayana Realm Spiritual Beasts, totaling 2,300, not counting some special Spiritual Beasts.
"Bai Ya, you take four True Immortal Spiritual Beasts and 800 Mahayana Realm Spiritual Beasts to guard the Number One City Wall."
"Tian Que, you're in charge of the Number Two City Wall. Your personnel will be the same as Bai Ya's."
"Ming Yujing and Bali, you two have always fought shoulder to shoulder, so I won't separate you. I'll give you the remaining three True Immortal Spiritual Beasts and 700 Mahayana Realm Spiritual Beasts. You'll mainly be responsible for the Number Five City Wall."
