Mu Yan smile, fingers again pluck string: "I hope we have a happy cooperation!" Outside the demon ape cave, the foundation of Tianjian gate is guarding diligently. But suddenly, the earth trembled, and countless sparks splashed out. Everyone was startled and backed away“ What's going on? Why are so many fireballs splashing out all of a sudden? "“ I hear the roar of the demon ape. Is the demon ape crazy? "“ It can't be true? Elder, are they going to be ok? " At the moment of panic, suddenly the splash of Mars stopped, and the roar of the demon ape weakened a lot. Instead, the melodious sound of the piano“ Why? How can there be a piano sound? And it's like a musician with auxiliary skills can play the piano? "“ Is there an assistant musician in tianjianmen? " Everyone looked at each other and saw the doubts on each other's faces. Did not wait for them to think clearly how can suddenly have the piano sound, suddenly like a meteor shower of fireballs splashing out. Bang bang!! This time, it's not just gravel wrapped in flames, it's huge molten rock. The people guarding at the door were scared to run away, straight away for hundreds of meters, before they were not powdered by these fireballs. Throughout the valley, the earth trembled violently. In an instant, the green grass and the elixir plants above were destroyed by the fireball "meteor shower". It took more than half an hour for such a violent shock to subside. The roar of the ape turned into a whine. But because the roar and roar disappeared, the melodious music became more vivid. At last, the disciples of Tianjian sect couldn't help but separate out a few people and carefully probe inside. Hao Zhixin is one of the outstanding young disciples of tianjianmen. Less than 40 years old, he was already a strong man at the peak of Yuan Dynasty. So this time, the leader gave him the responsibility to guard the cave. Now, there are strange movements and strange music in the caves. Hao Zhixin was not at ease, so he took a few younger martial brothers into the cave. When the scene in the cave came into view, Hao Zhixin and others showed an incredible look. In the lava pool in the center of the cave, the demon ape is covered with wounds, and its cry is full of pain. But the three elders of tianjianmen are not much better. Their ice armor is almost broken. There are signs of burns all over the skin. On the ground of the cave lie many Tianjian disciples, who don't know whether they are living or dead. But what attracted Hao Zhixin's attention for the first time was not the scene of the fierce struggle. It's a girl floating in the air, playing the piano slowly. In the flaming cave, the girl's face is not real. But that kind of ethereal feeling, but let unconsciously be surprised, attracted, even fascinated. Hao Zhixin's heart suddenly jumped and asked in a low voice, "who is this girl? When did you come in? " The people around them all shook their heads. However, it can be seen that the girl should be helping tianjianmen. With the piano playing, you can see the pale face of the girl and the sweat drops on her forehead. And the sound of the piano is in the ear, but it is rapidly replenishing the spiritual power in their bodies and repairing the injuries on their bodies“ Elder martial brother, what should we do? Are you going to help them? " Hao Zhixin hesitated and was about to answer.
