Because when he was in heaven, Dr. Hu gave some detailed explanations on the characteristics of Caiyu day by day according to the master's information.

Among them, Dr. Hu emphasized one point.

That is, when the night comes, Caiyu's vigilance will be raised to the extreme, and even sleep will always pay attention to everything around him.

And the cave that this colorful feather chooses day by day is an extremely empty cave, and the sound here will be amplified to the extreme, so the slightest movement will disturb it.

Don't look at it now sleeping with its head curled up in its wings, it's actually very alert.

The two didn't startle the snake.

It's not that he doesn't have the confidence to take it, but Dr. Hu is ready to come up with a better plan to make sure nothing goes wrong.

This involves another special ability of Rainbow Feather Childish.

Energy storage.

Rainbow Feathers can absorb and store a portion of the solar energy during the day, and when they encounter irresistible difficulties at night, they will release this energy and burst out with the same powerful strength as during the day. And the most important thing is that it can control the use of this energy.

And once it uses this ability, it is almost impossible for Zao Wou-Ki and Dr. Hu, who are not familiar with this cave at all, to catch Cai Yu and become childish, and Flender, who is guarding outside, is likely to be caught off guard and let him slip away. At the same time, there is also the uncertainty of this cave, which is not necessarily the only exit.

So this kind of time is not the time to pay attention to enthusiasm and recklessness.

You are reckless, but the other side will not be reckless with you!

If you lose, it's a little life, and it becomes a soul ring and dinner, and if you win, it's not good, you still have to change places and start over.

So it's not stupid, it's not good to fight or not, why fight if you can run?

So Dr. Hu waved his hand, and a big stone suddenly appeared in place.

Zao Wou-Ki had never seen this thing, so he immediately asked puzzled.

Dr. Hu crossed his hands on his hips and looked at the work in front of him very proudly, "This is eavesdropping 2.0. It's my latest proud work of Dr. Hu, with snooping camouflage and the ultimate noise reduction function, even if you sing K inside, you still forget about singing K, and people outside the singing will not hear it at all. ”

"Mr. Zhao, don't look at this looks like a huge stone, but its weight is very light, this stone is actually hollow, not only that, there is a layer of earthquake-resistant cotton filling in the middle of this stone wall, and even as long as you don't knock it, you won't find that this is a hollow. At the same time, because it is very lightweight, it can be moved around very easily. ”

This is Dr. Hu's further modification of the camouflage of the stone that was found after the last Bibi Dong knocking on the door.

As the saying goes, there will be no progress without actual combat testing, and after the last actual battle, Dr. Hu found that the original work was full of flaws.

One of the most important points is that mobile performance and noise cancellation are not taken into account.

Noise cancellation is a top priority.

Because Dr. Hu guessed that the last time Bibi Dong discovered their disguise, it must have been because a few of them were talking too loudly and were discovered by Bibi Dong who was passing by.

After all, the more powerful a person's body is, the more sensitive the senses are, and it is difficult for some subtle sounds to escape their ears, so Dr. Hu spent half a year of free time focusing on various changes to its noise reduction function, both inside and out.

The result is a new product with the highest noise reduction capacity.

Eavesdropping 2.0.

Because the name is new, the old version is named Eavesdropping 1.0.

Of course, what Dr. Hu didn't know was that this design still had no effect on Bibi Dong...... Ahem~

In the face of Dr. Hu's explanation, Zao Wouji's eyes widened and he looked confused.

Are people so idle now?

And after entering the eavesdropping storm 2.0, the speechlessness in Zao Wou-ki's heart became even stronger.

In between, Dr. Hu took out two pairs of shoes that looked very light and handed him a pair.

"Mr. Zhao, this is a special silent shoe, with its unique soft characteristics and full cushioning insole, which can minimize noise. I call them the Demacia Grass Shoes. ”

Demacia Grass Shoes?

What the hell is this name?

Twitching his mouth, Zao Wou-Ki put on the Demacia Grass Shoes. Zao then discovered that Dr. Hu was not boasting, but that the shoes really worked.

Originally, the two of them walked in this cave, in order not to disturb Cai Yu, they walked very lightly, and they had to speak very quietly. And now he tried to say two words, and found that there was no echo that might have existed, and the sound under his feet was completely gone. Not only can he walk normally, he can even jump!

Dr. Hu then opened a small window inside, pulled out the telescope, and then swapped out another telescope from the soul guide.

A special gadget that senses temperature.

However, this thing is not as good as infrared detection, and only a patch of black and a yellow color blob can be seen on the lens. Even if it's used to see people, it's pretty much the same.

The result is an oval-shaped, warm color ophore.

However, it cannot be used to see things, but it is perfect for judging the distance from the target.

But even with such a tool, Dr. Hu is still a little uneasy.

His eyes turned to the hole where they had come.

In the end, Dr. Hu did not forget to arrange five layers of nets, three layers of barbed wire, and two layers of hemp nets at the entrance of the cave, and then set up some sharp spears on the rock wall of the cave, which was to prevent Zao Wou-Ki and him from making a mistake and preparing a slowdown package for Cai Yu to become childish.

The spear will make Cai Yu unable to accelerate boldly with confidence, because once the deceleration is not timely, then it will hit the muzzle of the gun, and if you don't die, you will be injured, and the net behind it will be simpler.

The first layer of iron mesh belongs to hard deceleration, and then the hemp mesh is soft deceleration, and then after soft deceleration, it is hard deceleration, then soft deceleration, and finally hard deceleration.

Dr. Wu refers to this as a combination of hard and soft.

Coupled with the toxin on it, Dr. Hu promised that even if it went out, it might be careful, and the sound of it hitting the iron net would also alert Flender outside.

Kill two birds with one stone.

After making sure that everything he could do was done, Dr. Hu satisfactorily retracted into the eavesdropping 2.0 and officially started the first step of the battle plan.

Suddenly, Zao Wou-Ki felt that he might be superfluous.

Especially when he saw the obstacles that Dr. Hu had set up, he was so chilled.

What kind of villain is this.

The cave was originally crooked, and this kid actually set up corner barriers at the first two corners.

The five-layer net came out at the big corner at the back, where there was not only a net, but also a spear in the net, and the spear was also slaughtered with poison.

What a dirty heart this is......

Even Zao Wou-Ki began to feel sad for this colorful feather day by day.

Why are you so attracted by this kid!

You see, this is not all arranged clearly~

Of course, the complaints in his heart belong to the complaints in his heart, but as the highest combat power on the ground, Zhao Wou-Ki still maintains a calm and relaxed elbow demeanor. Hold your hands on your chest and watch the play.

What do you say let him control this, what eavesdropping 2.0?

So why do you need Dr. Hu? Isn't he the driver?

The plan went very smoothly, and the eavesdropping Fengyun 2.0 successfully reached the range of five meters of Caiyu's daily childishness, and this silly stupid bird still didn't feel the obvious abnormality, although he raised his head to probe during the period, he didn't notice the approaching eavesdropping Fengyun 2.

And this is also in Dr. Hu's estimate.

After all, Caiyu is a light-seeing creature that belongs to the daytime, and its sensitivity to changes in the night environment is not as strong as imagined, and eavesdropping on Fengyun 2.0 is originally a stone, and it is not easy to feel anything.

But even so, when Dr. Hu and Zao Wou-Ki got closer to within three meters, Cai Yu's strong sense of crisis still made it release Dr. Hu's ill-intentioned eyes.

Cai Yu first looked at Dr. Hu's eyes for a moment, and then the hairs all over his body stood up in an instant, and an unprecedented fear appeared in his heart.

Obviously, he is already so cautious, why are there still Diao people mixed up in this kind of place!!

Dr. Wu: We like you!

Cai Yu is childish: No, you are just greedy for my body, my soul ring and soul skills!

Run, you have to run, you have to run as fast as you can.

A strong sense of crisis made Caiyu subconsciously prepare to burst out of his accumulated energy.

Dr. Hu lifted the eavesdropping wind and rain 2.0 "Teacher, do it!" ”

Zao Wou-Ki instantly completed the possession of the martial soul, and the soul rings on his body lit up in turn.

"Third Soul Skill: Gravity Enhancement!"

"Fifth Soul Technique: Gravity Squeeze!"

"Second Soul Technique: Mighty King Kong Palm!"

Gravity enhancement suppression, gravity squeezing and pulling monsters, and strong King Kong palm output, this is Zao Wou-ki's most commonly used package, and there is almost no one within five meters of this set who can not eat his blow. The sum of these three tricks is not a matter of one plus one equaling 2. Many enemies ate his trick and directly opened a hole in the chest.

Of course, they can't be blurred, so go straight to GG.

However, although Zao Wou-ki's movements were fast, they were still a beat slower than Cai Yu's childishness.

A burst of white light lit up from his body, and the colorful feathers directly resisted Zao Wou-ki's move, and then turned over with a claw, leaving three claw marks on Zao Wou-ki's arm.

Zhao Wuji didn't open the first soul technique to increase defense, and the sharp claws of the soul beasts of the 10,000-year-level were always a little worse, and the blood splattered out, sprinkling the colorful feathers day by day. Cai Yu didn't pay attention to any of this at all, and after getting rid of Zao Wou-Ki's attack with one claw, it rushed headlong into the hole where it entered.

It's going to get out of here as fast as it can.

Of course, even so, it still hasn't let its guard down, and experience has taught it that humans are cunning, and their favorite thing to do is ambush it around corners that it can't see.

So it deliberately slowed down and even paused around the corner.

Sure enough, rows of spears blocked the way.

It's a small thing, though. Rainbow Feather flew over the area as if dancing on the tip of a knife, but when it came, it realized that it was just an appetizer.

A wire net and countless spears blocked the way.

Damn humans!

But this level will not stop its determination to survive, even if it is injured, but as long as it can survive, it is excellent. Therefore, Caiyu burst out with the greatest strength and found an area where the spears were not densely populated, and crashed into it......

And then......

Then it was caught in the hemp net behind it......

Because of the hard iron net, there are many small wounds on its body, and the toxin on the soft hemp net that is trapped enters Caiyu Zhizhi's body along the wound, and Caiyu Zhizhi, who was already twisted by the hemp net, slowly began to become unconscious under the action of the toxin.

looked at the iron net and hemp net that were still blocking the way after this, and then looked at the hemp net Caiyu who was holding himself, and there was only despair left in his heart.

And a minute later, as it was about to fall asleep from the toxin, it saw the terrified eyes it had just seen.

But this time, Caiyu was no longer frightened, and Caiyu felt calmer than ever.

Yes, it has resigned itself to its fate.

It's not that I'm not cowardly enough.

It's that the other party is too dirty.

Humans are so dirty.

Everything is calculated......

It died unjustly.

Zao Wou-Ki glanced sympathetically at Cai Yu, who had closed his eyes, but it was not completely dead.

The body of the 10,000-year-old soul beast is not something that this toxin can kill quickly, and even as long as it is released, it will probably not be long before it can find some way to remove some of the toxins, and then resist this wave. But......

Zhao Wou-Ki looked at Doctor Hu, who was still putting simple spears into the soul guide behind him, and felt a chill down his spine.

How can people be so dirty?

Well, I seem to have scolded myself too.

But I, Zao Wou-Ki, am really not that kind of person. I'm honest and kind...... Well, I'm a tough guy......

Finally, after Dr. Hu recovered most of the props, he left the last hemp net before he walked in front of Caiyu Zhizhi and took out a knife to end Caiyu Zhizhi. drew an end to his unwilling to be ordinary life.

Then the overflowing soul power condensed into a black soul ring in front of Cai Yu Zhizhi.

But before that was over, another ball of white light flashed, and a milky white chicken paw fell in front of Dr. Hu.

Zao Wou-Ki was stunned?

He had never seen anything like that.

But haven't you ever eaten pork and never seen a pig run?

This is the appearance of the legendary soul bone.

At this moment, even Zao Wou-ki, who had been calm, was completely sour.

"What kind of shit luck did you kid take, and you still have soul bones?!"

Dr. Hu took back the last net, and Cai Yu was already completely GG, so it was no longer necessary to keep these.

Grabbing this milky white chicken paw with one hand, the more Dr. Hu looked at it, the more he felt that it was very similar to a thing he had seen in his previous life.

Isn't this just pickled pepper chicken feet?!

"Stinky boy, don't be stunned, hurry up and absorb the soul ring, and then absorb the soul bone when you're done, I'll go outside and call Flender over, you hurry up."

Since this cave can be selected by Cai Yu as a temporary place to live, it is naturally safe, so it is also very safe for Dr. Hu to absorb the soul ring. At least not as much as worrying about the threat inside the cave.

Doctor Hu looked at Zao Wou-Ki gratefully, then sat down cross-legged, showing his martial soul and began to absorb the soul ring.

And at the moment when he took out the martial soul in front of the soul ring, the staff of the angel ...... The hammer of judgment shook.

As if to say: Ahhhh

As soon as the soul ring was attracted to it, it began to absorb it frantically.

And the accompanying great wave of soul power, Dr. Hu also had to close his eyes and began to adjust.

Normally, the fourth soul ring of the soul master is to choose a soul beast soul ring of about 5,000 years, and no matter how high it is, it will not choose a 10,000-year soul ring.

And the reason why Zao Wou-Ki and Flender still helped Dr. Hu hunt even though they knew that Cai Yu was a 10,000-year-old soul beast was because of Tang San.

Tang San's fourth soul ring was the Ten Thousand Year Soul Ring.

Humans have a habitual perception that once something appears once, it will not be so surprised when it appears a second time.

And Tang San's experience, under the master's explanation, they also understood that physical fitness was a hardcore condition, and Doctor Hu, who obviously had physical fitness that did not belong to Tang San, naturally also had such a condition.

This is also one of the reasons why Dr. Hu dares to do this, and at the same time, because of the soul power protected by the Northern Spiritual Skill, I can't use it, can't I still suck it?

As long as it doesn't exceed the amount of his own soul power, Dr. Hu has no worries at all.

And the subsequent soul ring absorption was indeed as smooth as expected. It's even a lot easier than Tang San who took his life.

After all, Dr. Hu's body has been developing in a perverted direction under the reinforcement of the Northern Spiritual Skill many times......

Then Dr. Hu picked up the pickled pepper chicken feet...... Colorful feathers are childish soul bones......
