In the cave.
Yu Daochen slowly opened his eyes. His lips were chapped, and his face was pale and weak. He eliminated the last trace of Yin energy and let out a long sigh, "Finally, the last bit of Yin energy is gone."
Yu Daochen tried to move, but his legs had gone numb from sitting cross-legged for so long, and he couldn't muster any strength.
Yu Daochen could only slowly shift his legs. It took him over twenty minutes to lie flat on the ground.
Yu Daochen was helpless and exclaimed, "Good heavens, how long has it been? Why am I so weak, as if I've been through ten rounds?"
Just as Yu Daochen was about to support himself and stand up, his body trembled. A searing pain shot from his chest, and the Yin energy that had disappeared suddenly reappeared all at once.
Yu Daochen clutched his chest, continuously spitting out Yin energy, his eyes turning blood red.
"This is bad. If this continues, I'm really finished."
Yu Daochen quickly mobilized the Qi within his body to suppress the suddenly berserk Yin energy, but it was utterly useless. His breathing became increasingly difficult, and the Qiankun Mirror stopped absorbing Yin energy.
Yu Daochen soon couldn't hold on any longer and closed his eyes, countless memories flooding his mind.
"Am I, Yu Daochen, going to die like this?"
"This is truly frustrating!"
Outside the waterfall, Liu Feng and Qin Muyu watched the situation at the cave entrance with nervous expressions.
A powerful wave of Yin energy emanated from the cave.
"What's going on?" Qin Muyu asked, preparing to enter.
Liu Feng was also unsure of what was happening inside.
As the two were about to enter, a figure slowly walked out.
Liu Feng and Qin Muyu both breathed a sigh of relief, their tense hearts finally settling.
"Wait!" Qin Muyu grabbed Liu Feng, who was about to step forward.
Yu Daochen slowly emerged from behind the waterfall. He was enveloped in black mist, his eyes blood red, and two crimson demonic horns protruded from his forehead. He grinned sinisterly, "Eat, eat, eat, eat, eat."
Liu Feng's expression changed, "Has she been backlashed?"
Qin Muyu took a closer look and shook his head, denying it, "No, it seems the fusion was successful."
Liu Feng was confused. If the fusion was successful, why did she look like this? "Then why is she like this?"
Qin Muyu stared at Yu Daochen, who was slowly walking towards them, "There are records in demonic arts that a successful fusion has a very small chance of triggering an initial berserk state. This should be what she looks like now."
Liu Feng's face was filled with worry, "Then what should we do?"
Qin Muyu smiled faintly, "It's simple. Beat her up, and wait for the berserk state to end."
Liu Feng breathed a sigh of relief upon hearing Qin Muyu's words. As long as she was alright.
"Step back, I'll do it." Liu Feng said, preparing to engage.
Qin Muyu rolled his eyes, "You're injured. Let me handle it."
Liu Feng nodded and stepped aside, "Be careful not to hurt her."
Qin Muyu scoffed, "Do you think I don't care about her?"
Qin Muyu stepped forward, raised a hand, and provocatively beckoned, "Come on, I'll let you have half my body."
Yu Daochen, having lost her reason, heard Qin Muyu's provocative words and charged forward, throwing a punch.
Qin Muyu smiled faintly. Dealing with such an irrational monster didn't require any techniques.
Just as Yu Daochen's fist was less than half a meter away from Qin Muyu, Qin Muyu extended a finger and blocked the powerful punch.
"Good strength, but still not enough."
As Qin Muyu's words fell, he raised his leg and delivered a knee strike to Yu Daochen's abdomen.
Yu Daochen's expression changed drastically. His entire body was sent flying backward and crashed into the pool.
Liu Feng, witnessing Qin Muyu's knee strike, cursed loudly, "Damn it, could you have been gentler? What if you broke her?"
Qin Muyu glared at Liu Feng, "If we don't exhaust her berserk Yin energy, she'll never regain her senses."
Liu Feng didn't listen to Qin Muyu's excuses, "But you didn't have to hit her that hard. Is this what you call caring for her?"
Qin Muyu gestured towards Yu Daochen, who was climbing out of the pool again, "See, she's fine."
Liu Feng glared unhappily, "Would you only be happy if something happened to her?"
Yu Daochen, enraged, charged at Qin Muyu again, baring her teeth to bite Qin Muyu's neck.
Qin Muyu bent his body, reached out, and covered Yu Daochen's entire face with his hand. Then, he exerted force, and Yu Daochen was sent flying again, crashing into the pool.
Liu Feng, seeing Qin Muyu's continued ruthlessness, had his eyes blazing with anger, "Damn it, don't hit her in the face! What if her beautiful face is ruined?"
Qin Muyu was extremely exasperated, "If I let her bite me, it would be disastrous."
Liu Feng ignored him, scolding like a shrew, "Would it kill you to let her bite you!"
Qin Muyu rolled his eyes, "You don't understand. If this were before, I wouldn't mind letting her bite me, or even suck all my blood. But now, influenced by the Yin energy, if she tastes fresh blood, she'll truly become a bloodthirsty monster."
Yu Daochen, like a zombie unaware of pain, climbed out of the pool again, but a quarter of the demonic energy on her body had dissipated.
Liu Feng instructed, "Can you please not hit her so hard?"
Qin Muyu was rendered speechless by Liu Feng's persistence, "The only way to exhaust her Yin energy is to fight her."
