Zhang Cheng looked at the cave in front of him. The cave had been cut open. But he always felt a little strange. There was something in mind, but the eyes didn't leave the cave one step. All these are accomplished by Zhang Cheng and Birdman's cooperation and continuous efforts.

All of a sudden, Zhang Cheng felt something strange. The cave he had dug kept spraying cool spring water without any expectation.

"No, there is a spring in the upper cave." Zhang Cheng exclaimed.

"Let's get out of the way." Zhang Cheng looked at the group.

"Don't panic, everyone. Come with me." Standing on one side of a birdman said slowly. Looking at the spring gushing out, he thought of leaving the place as soon as possible.

"Well, don't hesitate to follow him out of here." Zhang Cheng cried out.

So the birdmen flew back to the ground with Zhang Cheng and some of them. To everyone's surprise and bewilderment, they saw that the mountain began to emit white gas.

"Come on, everyone! The mountain is starting to smoke white. " A man exclaimed, pointing to the mountain and looking at everyone.

"Don't be nervous. There's nothing special about this white spirit."

"How to explain these white Qi?" A birdman standing on one side asked.

"Hum ~" Zhang Cheng said with a smile.

"The reason why this mountain is emitting white gas is that there is aura before this mountain"

"the spirit that gathers all natural things, Mountain Sun and moon breath itself? Such aura is really rare. In addition, it belongs to the nature of all things. It's even rarer, "someone continued.

"Yes, it's true, but now for some reason, aura is sealed, and the geographical location here is not very good, so it's hard for the sun to gather its own temperature. In addition, the environment is very dark, so it's hard for aura to mix with nature. " Zhang Chengtou said slowly.

"Unfortunately, now that we've made a hole in the cave, Lingqi collides with the air outside the mountain. To achieve a certain degree of fit and just in the middle, so the mountain began to appear white, it can be said that it should be self adjustment. There is no problem in saying that. " Zhang Cheng looked at those white Qi, turned around and said to everyone. The natural aura of mountains is really interesting. Zhang Cheng unconsciously curved his eyebrows and eyes and gently raised his lips. That handsome face looks more charming. But he didn't know how confident he was.

"Oh, I see. That really makes sense. " It suddenly dawned on everyone that everything in the world is still reserved for explanation. Calm down, in fact, everything can be explained. There's no need to make a fuss.

"The natural aura of the mountains, after many years, has been used in China. It seems to be a pity." The Birdman King slowly looks at Zhang Cheng. There's something in my heart that I can't tell. Only he knows what it is like.

"Oh, yes! Zhang Cheng, I heard that you are leaving now? Is that true? " The king of Birdman asked. He was a little reluctant to leave now. Zhang Cheng's talent and ability are even more rare to him. He hopes that his staff can have such a powerful person. It is his honor to serve himself and the well-being of the whole country. But it's just thinking about it. If he is ready to leave himself, there is no means to keep him. Let alone an excuse to keep him. After all, everyone has his own way to go. Everyone has something they want to get and protect.

Zhang Cheng heard the King say so. Turn around and look at the king of Birdman.

"Your Majesty, yes! We really need to get out of here. Besides, we are in a hurry recently. It doesn't seem that we still have a task. So I can't stay here long. And I hope you'll forgive me. " Zhang Cheng replied.

"That's nature." The king of Birdman looks at Zhang Cheng with a smile, but he always wants to say something in his eyes.

"Since you have important business, I can't force you or keep you more. A good man is ambitious. Nature has something important to do At the same time, the king of Birdman reached out and opened his hand. It's true that he has something to give them. This is the last thing he can do for them.

"I have nothing to give you. I have a feather for you. I hope it can help you through when you are in trouble. " At the same time, Birdman gave me a blue feather in the palm of the king's hand, which was shining, showing its difference.

"Don't look down on it. He is different from ordinary feathers The king of Lilliputian looked at the feather in his hand.

"This is my most precious feather. It's different from ordinary feathers. It has special energy. From the ancient legend down, has gathered all things aura. He has his own strength. Today I will give it to you, and I hope you can accept it. Of course, I hope I can help you in the future. " The king of Birdman sincerely told Zhang Cheng that he seemed to have a kind of expectation for him, and at the same time, he had a kind of heartache. Although this is his and Zhang Cheng's "all right, your majesty," Zhang Cheng leaned over and reached for the feather. "That's where I thank your majesty." Zhang Cheng looked at the king of the two people's country, and there was an indescribable gratitude in his eyes. Then put it in the collection box. This feather is really different from the ordinary feather, and it will be useful in the future. Then look forward to his surprise.
