Let's move the story back a bit.
Five minutes before the exam ended.
When Feng Luotian was selecting his monster cores, Mei Yue'er retrieved the injured Ying Lizhua and met up with the rest of the party at the rendezvous point.
She then distributed Theríon Recovery Pills and Basic Healing Pills for everyone to recuperate their strength.
But Ying Lizhua refused to take it because not only did his pride not allow it, he would like to reserve his blood loss percentage to maximize his damage in their last move.
Mei Yue'er did not bother with the guy's attitude.
She turned around and gave a hard slap to Sun Wuji, whose face was already covered in blood.
With a knock, Sun Wuji immediately woke up.
Mei Yue'er was with him long enough to know that even though his mind was blank and his face was blood-soaked, Sun Wuji was the most tenacious when it came to life force, so a little slap would not give him any pain at all.
