First, let Ling Yi and the others intercept Liu Minggong's team, killing only a few people while leaving several alive.
Let the outsiders think their purpose is only because of the mutants.
Leaving the lives of Liu Minggong's other team members is to avoid suspicion if Liu Minggong were the only survivor.
In times of life-threatening danger, timely rescue would further make Liu Minggong grateful.
Then, it's about how to make Liu Minggong completely trust oneself.
Now, even hiding things from his own father, it's evident he truly completely trusts this master in front of him.
The situation at the time was so critical; after falling down the slope, it was indeed the severe shock that made the already injured Liu Minggong faint.
But in fact, he didn't faint for that long; he gradually woke up while Lingze was channeling energy to heal him.
