Gu Yan kept thinking, and released his mental energy to find the weakness on King Yaozhi.

   After observing around, although I found several weaknesses in the Demon Zhi King, Yu Qingqian's strength could not touch the opponent's body at all, and it was difficult to break through them one by one.

   "Does King Yaozhi have anything to be afraid of? Or can he use some restraint?" He couldn't help but ask the Spirit of the Secret Realm in his hand.

   The eyes of the spirit of the secret realm kept rolling, thinking for a while, and suddenly his eyes lit up.

   "By the way, King Yaozhi likes rhythm, and the guardian of the secret realm of Lingxi will often play the piano and flute, and use this to suppress it. Every time he hears that note, King Yaozhi will fall asleep quietly."

  Gu Yan's eyes lit up at the same time, "I hope this method works."

   So he immediately sent Yu Qingqian the method that the spirit of the secret realm said.

  Yu Qingqian was smashing the master-level poison refined in the low-level continent into King Yaozhi, and the infiltration of the poison also caused the opponent a headache.

The direction of   's attack shifted from Doudou to Yu Qingqian.

   However, the Demon Emperor Grass was on Doudou's body, and he could teleport with it in an instant. After Yu Qingqian was swept away a few times, Doudou appeared in front of her and resisted King Yaozhi's attack.

   Hearing Gu Yan's words, Yu Qingqian wiped the blood on his lips, the five internal organs in the abdomen felt as if they were dislocated, burning and hurting, and the wood-based healing power continued to work in the inner abdomen.

   Yu Qingqian hadn't been injured so badly for a long time, but she didn't have the slightest fear, instead she showed a fighting spirit and faith.

What    needs is this kind of stimulation, so that she will find that her cultivation base lacks too much strength, and she needs to keep getting stronger.

   "Sick beauty, the spirit of the secret realm said that King Yaozhi may fall asleep peacefully when he hears the rhythm. Let's try it together." Yu Qingqian dodged and landed next to Feng Chen.

   "Okay!" Feng Chen took out the simple and dark guqin that he got at the treasure hunt and put it in front of him.

   Yu Qingqian also took out the crimson guqin, put it in front of him, and sat in a circle, playing it a few times before.

  The ethereal and crisp sound came from the guqin, and the deep black guqin also seemed to be unwilling, and made a Weng Ming.

  Feng Chen's fair and slender fingers landed on the strings, looked up and looked at Yu Qingqian, the two of them plucked the strings in perfect harmony.

   A melodious and gentle tune poured out from the two guqins, and the notes with charm were injected into the spiritual power of the two, circling and echoing around.

  The two were completely immersed in the qin music, and the ensemble tune and the guqin produced a sense of incomparable resonance.

  Suddenly, a crimson light shot straight into the sky from Yu Qingqian's guqin, instantly turning into a phoenix spreading its wings and making a loud cry.

   Then, Feng Chen's quaint and dark guqin seemed to resonate in response, and a black light swept out, turning into a giant dragon with a cold and stern power, roaring up to the sky.

  The phoenix and the giant dragon circled and intersected in mid-air, and finally turned into two light spots, one red and one black, and penetrated into King Yaozhi's body.

   King Yaozhi, who was still irritable and angry, gradually calmed down when he heard the gentle note, and the vines attacking Doudou also became much slower.

   As two light spots, one red and one black, drilled into its body, a slow-paced music reverberated in the sea of ​​consciousness of King Yaozhi.

   It wants to control its mind and not sink, but it cannot escape the influence of the jumping notes in the sea of ​​​​knowledge.

   Gradually, the humanized face of King Yaozhi showed a hint of sleepiness, and slowly closed his eyes. The body sank into the river little by little, and the spreading vines sank into the ground.

   Including the vines holding the small ball that sealed Shixi, and they also fell silent into the river.
