Chapter 521

When Cao Ke came to the entrance of the mountain and saw Phoenix who had been waiting for a long time, Phoenix's face was not only impatient, but also full of helplessness!

He flapped his wings twice and fell on Cao Ke's shoulder. Phoenix said angrily: "Cao Ke boy, you're not in a hurry. What's the time? It'll be noon in a little while! You don't know if the way to deal with those little tree people is feasible. Can't you be more proactive? "

Cao Kesi said, "what's the hurry? My method can work. We should be able to reach the deepest part of the cave and find the natural debris in a short time! If my method doesn't work, let's just retreat and get out of the cave! Wait to go back and think of something else! What's the use of worrying? Worry can make you achieve your goal faster? Hum! Worry will only make you mess up first! "

"Yes, yes!" Phoenix quickly flapped his wings and said: "I don't argue with you about these big principles. Just tell me what I need to do when I get into the cave! I'm too lazy to care about other things! "

Phoenix asked the question a little bit, and zouk thought it over carefully, and then solemnly said to it: "your task is to ensure that the gain state of those blessings on me will not disappear and stop! I'll take the lead and attack! If there's a little tree man in the rear who doesn't give up, try to stop him! That's all right with you, isn't it? "

Phoenix didn't even think about it and said, "no problem! It's easy for me to keep the gain state and deal with the catching up little tree people

"That's no problem!" Seeing that Phoenix agreed with his opinion, Cao kesui nodded his head mercilessly: "let's go now?"

"Get up!" Phoenix waved his wings and screamed.

Cao Ke smell speech where still need to hesitate, fast tiptoe a little bit, so a flash, rushed into the cave! Almost at the same time with Cao Ke, Phoenix's enchantment magic gradually fell on Cao Ke! That kind of power full of surging feeling, and again in the body of Cao Ke wantonly up! Cao Ke's heart suddenly had a kind of extremely excited emotion. He wanted to let it out immediately

It was almost the same as when they first entered the cave. After only two minutes of galloping in the cave, Phoenix, standing on Cao Ke's shoulder, issued a warning: "be careful, the first wave of little tree people will soon arrive!"

After being reminded by Phoenix, Cao Ke immediately thought about it. Three Unicorn fireballs of the size of a basketball jumped out and took their places!

As soon as the first wave of little tree people appeared in the sight of Cao Ke and Phoenix, Cao Ke suddenly gave a big drink. With a strong wave of his right palm, a torrent of fire spewed out from the unicorn fireball on his right palm! In an instant, the whole cave space filled in front of us!

Poor first wave of little tree people, many of them even didn't have time to see what the enemy looked like. In this fire attack of Cao Ke, they were burned to ashes! Sad into the state of resurrection!

"Hold on!" Cao Ke was so happy to see his success that he said a word to Phoenix. Then he turned his whole body into a high-speed rotary drill, chasing the tail of the fire attack he had sent out before, and passed the position where the first wave of saplings were destroyed!

When the fire attack was exhausted and finally dissipated in the air, Cao Ke also fell to the ground and continued to run forward without any reduction in speed! Phoenix, who has been standing on Cao Ke's shoulder, did not have the opportunity to look back until this time to see the place where the little tree people were destroyed. However, it was surprised to find that those little tree people who had strong vitality in its consciousness did not even have the situation that they were about to revive! We can see how fast Cao Ke's attack and forward speed are!

"Beautiful Until the first wave of the little tree people's debris completely disappeared in their own vision, Phoenix turned around happily and chirped: "Zoke! Did you see it? Did you see? Your method of rapid advance is really effective! As long as you can continue to maintain the current speed, even if those little trees are resurrected, they will never catch up with you! "

"I didn't pay any attention to those little tree people. What I worried about was another thing..." Cao Ke's face was not as excited as Phoenix. After listening to Phoenix, Cao Ke murmured to himself: "maybe our real trouble is the moment we see the natural debris..."

The excited Phoenix Contact obviously didn't hear what Cao Ke said clearly, and subconsciously asked, "what did you say, Cao Ke boy? I didn't hear you

"If I don't hear you clearly, I'll forget it!" Cao Ke is very helpless to answer a way: "you carry out your own task to go well!"

"Don't worry! It's all right Phoenix patted his chest confidently.

As Cao Ke expected, with the help of Phoenix's gain, he was not able to compete with a wave of more than a dozen small tree people! Those little tree people were killed by Cao Ke as soon as they came out. After 50 waves of small tree people were killed, Cao Ke's speed didn't drop even a little. It was like a jumping lightning all the time, moving around in the narrow cave space at a high speed!

It's another blow to wipe out a wave of little tree people! Phoenix stares at his small eyes and looks deep into the dark cave. He can't help but curse: "he's a real cat! At your speed, from the time we met the first wave of little tree people, our galloping distance is not dozens of kilometers! Why don't I have the feeling that I'm going to reach the deepest part of the cave? Who built this cave? Is there a head? "

Cao Ke frowned and said, "yes! Even if I have the help of Kirin fire, the power consumption is not so huge, but I can't stand such endless output Tens of kilometers deep cave, this is really some fabulous!... "

After a pause, Cao Ke turned his head and said to Phoenix, "stupid bird, do you have any way to explore the depth of the cave first?"

Phoenix a Leng, thought for a while, should say: "there is a way, that is, I don't know whether it works or not."

"No problem! If you have a way, use it as soon as possible! " Cao Ke urged: "now I have to get a general data to let me know how long I need to stay in this state. If the cave is still very deep, then I have to consider whether I should quit the cave first... After all, my source is limited, so I have to leave some for our retreat! Now behind us, it is estimated that more than 40 waves of little tree people can recover! These are obstacles and stumbling blocks for us to retreat safely! "

"Well!" Phoenix naturally understood what zouk meant, and saw it take a breath, then opened its small mouth like a hook, and let out a scream towards the depth of the cave!

This scream is essentially different from the ordinary one! Ordinary shrieks are equally sharp, but they spread outward in a divergent form. The closer you stand to the sound source, the louder you hear. And Phoenix's scream, as early as its throat brewing time, was its source force beam into a thin thread! Even when chouk, who is only a few centimeters away from Phoenix, hears the scream of Phoenix, he thinks that his ears are out of order... Is the sound similar to the sound of a mosquito made by a phoenix like Phoenix? Are you kidding? How long has Phoenix not had a good meal to make its voice sound so feeble

In fact, what Cao Ke didn't know was that the reason why he heard the scream of Phoenix was so small was completely determined by the particularity of the scream! Phoenix has been forced into a thin line of sound, most of the natural direction of transmission is in front of Phoenix! The sound that Zoke heard next to Phoenix was just the sound that the real scream leaked out in the process of transmission, which caused the secondary formation of air fluctuation!

If Zoke is right in front of Phoenix, the cry of Phoenix that Zoke can hear will even shatter his eardrum!

Phoenix has its own consideration in this way of screaming! Cao Ke asked Phoenix to explore the depth of the cave. Phoenix had no way to explore it by himself, and voice became the best means of exploration! Phoenix uses its unique "force sound into a line" skill to project sound deep into the cave. Once the sound reaches the bottom of the cave, it will naturally be bounced back by the cave wall. In this way, Phoenix will be able to rely on the volume, time and other factors of the rebounded sound, Roughly judge how long they have to go from the deepest part of the cave!

In order to make the sound complete such a long-distance exploration and then bounce back, Phoenix must concentrate the direction of sound transmission as much as possible. In this way, it will naturally form this strange situation in front of us. Only in this way can Cao Ke, who is close to it, hear its call like a mosquito humming
