Guided by the clues provided by the Antarctic Immortal, Xiaotian Quan, Xiaoqing, Bai Suzhen and Fahai finally found Frogface's real hiding place - an extinct volcano crater.The mountains were covered with green trees, but Roaring Sky Dog felt a heat wave that was about to start.He concluded that this must be the place of Yin and Yang mentioned by the Antarctic Immortal.However, several people searched around for a long time, but could not find the entrance to the volcano.Seeing that it is getting dark, when the sun rises again, the seven-day limit is almost over, and the frog face will merge with the dragon horn to gain the power of the dragon.Time was running out, and Tengu decided to take a risk.He blindfolded his eyes and used his sense of smell to determine the location of the cave entrance. Under the guidance of the tengu, everyone rushed into the cave... Qingbai opened his eyes and saw that he was already in the cave. He was surprised, but he was unsteady on his feet. Only then did he realize that he was in the cave.In the whirlpool of fire clouds.Bai Suzhen unfolded the Yunlei cloak and took Xiaoqing out of the whirlpool, while Fahai also used the wind and fire cassock to rescue the Roaring Dog.The four of them stopped on the cave wall, looking for a way into the depths of the cave. However, they found that the cave was surrounded by stone walls and there was no exit at all.It seems that this is another deception trick used by Frog Face.Xiao Qing asked Tengu to blindfold him and search again. This time, Tengu used his hearing to find that the entrance of the cave was in the whirlpool of fire clouds.The four of them ventured into the whirlpool.In the whirlpool of fire clouds, Fa Hai fell into trouble and was separated from everyone.Qingbai decided to follow the Tengu straight into the depths of the cave.The three finally arrived at the frog-faced water snake.There is a clear spring inside the cave, and the frog-faced water snake is meditating in the open space in the clear spring.And the pair of dragon horns were already on top of the frog-faced water snake.The green and white water crossed the clear spring to kill the frog-faced water snake, while the roaring dog pounced on the frog-faced men, blocking the shrimp soldiers and crab generals aside.Qing and Bai used their purple-gold hooks to hook the dragon's horns with all their moves. Frog Face gradually became unable to withstand it. One of them accidentally got hooked by the purple-gold hook and the dragon's horns were about to be taken away by Qingbai!At this moment, a ray of morning sun shines in from the top of the cave, the sun rises from the side of the mountain, and the sun and moon appear in the sky. This is a moment of yin and yang in the whole sky, and it is also the final fusion of dragon horns and frog faces.time.The dragon horn on Frogface's head suddenly became more powerful and shook open the purple gold hook.Seeing the frog face absorbing the energy of the sun and the moon, gradually becoming a dragon, Qingbai became more and more desperate.Suddenly, the Tengu jumped up to the top of the cave and ran towards the sun.It turns out that the Tengu planned to swallow the sun to buy time for Qingbai.The sun was swallowed by the Tengu, and the earth became pitch black again.The energy Frogface had just gained disappeared.However, Tengu can only swallow the sun for a quarter of an hour. If Tengu does not spit out the sun by then, it will be burned to ashes.
