"Boom!" After a long time, a deafening explosion sounded in the stone chamber, and the entire cave trembled violently, but fortunately, this stone chamber was strong enough to withstand such a powerful blast impact.

Ah Tu twisted the ball body and turned to the stone door in the stone room inside, scratched the ball-like head with a cute purple hand, and let out a low "woo" sound from his mouth, Mu Yun also ran to the stone gate very worriedly, and pushed the stone door with her hands, but the stone gate did not move, so she raised her aura to the peak state and began to cast earth magic.

"O holy god of earth! Please give me ......" As soon as Mu Yun was halfway through the mantra, the stone gate opened from the inside with a "boom", and billowing smoke poured out, "Ahem, cough, cough!" A moment later, there was a coughing sound from inside, and after a while, the red-haired old man rushed out in disgrace, and the placket of his clothes had become tattered, and even his red hair was burned to black, and he looked extremely embarrassed.

"Poof! Hahaha! Mu Yun couldn't help but laugh, and burst out laughing, even Ah Tu trembled with joy, and there was a low sound similar to laughter from the sphere.

"Two little things, how dare they laugh at the old man!" The red-haired old man pinched his waist with both hands, and looked at the person and ball in front of him with a feigned anger, "Believe it or not, the old man will refine the two of you in a while!" ”

Ah Tu was so frightened that he hurriedly covered what looked like his mouth with his two small purple hands, and his whole body began to tremble slightly.

"Mr. Fire Dragon, you better spare me," Mu Yun pretended to be very scared and said, "Your success rate is extremely low, if I fail to be refined by you, there will be no second Mu Yun to repair me." With that, she covered her mouth and snickered.

"Who told you that the old man failed this time?" The red-haired old man raised his old face and said proudly, "The old man has succeeded in all of them this time!" ”

"All successful?" Mu Yun and Ah Tu both looked at the red-haired old man with a look of disbelief, "Just brag!" Mu Yun raised his little face and put on a posture that was even more proud than the other party, "Then what happened to the explosion just now?" ”

"Hahaha!" The red-haired old man smiled heartily and said, "Just now the old man tried to test the power of these treasures, so if I accidentally didn't control them, there was an explosion, but fortunately, I used the power of the spatial source in advance, otherwise, the old man's dragon nest would have been blown up." ”

"The source of space?" Mu Yun's eyes widened, and he looked directly at the red-haired old man, "Do you actually have such a thing?" As she spoke, there was a look of extreme greed in her eyes, and it was the red-haired old man's turn to worry.

"Hey, what are you going to do?" The red-haired old man folded his hands on his chest and stepped back nervously.

"Hey, hey, hey!" Mu Yun smiled evilly, "Dear Mr. Fire Dragon, can you show me your spatial source?" ”

"No way!" The red-haired old man didn't think about it, and refused in one bite, "This is the lifeblood of the old man, how can I give it to you?" ”

"Ugh!" Hearing this, Mu Yun felt very awkward, "Why did you suddenly become so stingy, you can't lose a piece of meat at a glance." ”

"Who knows what you think in your little head?" The red-haired old man's face looked very vigilant, "In case the source of this space confesses to you again, then the old man really has nothing!" ”

"Buzz!" As soon as the red-haired old man's words fell, a piece of silver light shone on his body, and then a transparent ball with a diameter of a foot suddenly appeared in front of him, and these silver rays were scattered from the ball, and this transparent ball floated in mid-air and flickered, which was the only source of space that Mu Yun lacked in the seven systems.
