The last time he entered the Black Mist Valley, Chu Chen had already been able to penetrate a distance of sixty zhang away.

This time, after coming to a distance of sixty zhang, the pressure Chu Chen felt was already very great...... Although he hadn't reached his limit yet, he didn't have the feeling of being at ease when he entered the last limit of Black Mist Valley after every time he grew up.

Sure enough, this time the evolution of Cheng dù is very limited, and he seems to have really encountered the bottleneck of evolution!

When Chu Chen penetrated into the distance of sixty-six zhang away from the Black Mist Valley, he could no longer advance a single cent.

Obviously, although the strength in Chu Chen's body has skyrocketed by several percent, it is only six zhang more advanced!

After sixty zhang, the pressure of each zhang is dozens of times that of before!

No, it's the limit. If you go any further, you'll really be crushed.

Feeling the vast and endless pressure ahead, Chu Chen sighed and slowly retreated.

The Black Hawk clone had fallen into the bottleneck of evolution, which made Chu Chen a little depressed.

In fact, this Black Hawk clone has already become his biggest reliance and means of pressing the bottom of the box, and it is by virtue of exploring the Black Mist Valley to hunt for treasure, and the current growth rate can no longer keep up with the need to go deep into the Black Mist Valley.

Do you want to leave some treasures there in vain? Absolutely not!

It is imperative that we find a way to solve this problem, and only when the Black Hawk clone becomes stronger and stronger, can his body become stronger and stronger.

Once Black Eagle reaches the limit, then his ontological cultivation will probably also be greatly restricted.

In the following time, Chu Chen spread his wings and roamed the void with some unbelief in evil, and flew almost all the iron mines within a radius of a million miles.

Whether it was refined iron ore, dark iron ore, hematite or some other rarer iron ore and ore, he almost tried it all over the time, but once all the iron ore entered his stomach, he could only be full, but he could no longer provide a trace of dark iron essence!

Tut...... What should I do?

Seeing that there was nothing to be done for the time being, Chu Chen flew to the eagle's nest above the Black Mist Valley to sleep after the Black Eagle clone had eaten up, and his consciousness quickly returned to his body.

In fact, until now, he still doesn't know what kind of beast this mysterious Black Hawk doppelganger is, so naturally he doesn't know how to make Black Hawk break through the evolutionary bottleneck.

Who should I ask about this......

An incredible thought suddenly flashed in Chu Chen's mind, who was frowning.

His face suddenly lit up, and he plunged his hand into his arms and pulled out a round ball of flesh.

"Chubby, I've raised you for so long, it's time for you to repay the favor, wake up!"

Chu Chen spread out the mouse rolled into a ball of meat with his two hands, and at the same time whispered a few times in its ear, "Every day you know that you eat, sleep, sleep and eat, you are still really a little white pig!"

"Oh, it's annoying, uneducated bad guy, don't you know it's rude to disturb people's sleep?"

The little hamster was obviously very upset when he was woken up, rubbed the corners of his eyes with his little paws, and yawned, "Uncle Ben is busy sleeping, don't disturb me!"

"By the way, the last time you dreamed of that black eagle, it seems to have appeared nearby......"

The corners of Chu Chen's mouth twitched, and before he finished speaking, he saw that the little hamster's face was not very good-looking.

"What, where's the eagle with the golden-winged ......?"

The little hamster looked horrified, its whole fat face became distorted by fear, its fat body trembled a few times, and it buried its head in Chu Chen's neck, its fat ass trembling all the time.

"Don't be so afraid?" Chu Chen took it out again.

"Of course I'm afraid, that ** thing can even eat the Nine Heavens Dark Iron, if Uncle Ben swallows it in one bite, it will really be doomed!"

"Then do you feel it?" Chu Chen asked deliberately tentatively.

"I've long felt wrong, I've long felt the breath of that ** thing!!"

The little hamster came out of Chu Chen's neck, crossed his waist, and looked angry, "Since Uncle Ben dreamed of it for the first time, it didn't feel right. Uncle Ben is the body of the Xuan Spirit, all diseases are invasive, and he has always slept very well, how could he have that kind of nightmare! It turns out that every qiē is your kid, it turns out that your kid's body actually has the breath of that ** eagle!"

Chu Chen's cold sweat almost flowed down, he really couldn't hide anything from this little hamster.

The little hamster stood on Chu Chen's shoulder, and sniffed Chu Chen's body fiercely, "Boy, I don't know where you got your shit luck from, your soul is actually contaminated with the breath of that ** guy, is it possible that you have taken it as a spirit **? But no, the breath of the spirit ** is not like this! Boy, you tell me honestly, what does it have to do with that guy?"

Chu Chen's eyes couldn't help jumping a few times after hearing this. I can only admit that this fat mouse really has two brushes, and he can actually sense the breath of the black eagle clone in his soul, and it seems that it is the right question to ask.

Thinking of this, Chu Chen pursed his lips quietly: "What is my relationship with it, I can't say this first, it will definitely not hurt you, but I have a question for you." ”

"Hmph, stinky boy, play tricks with Uncle Ben, come on, what trouble are you in this time? ”

The little hamster's expression suddenly relaxed, and this old fritter could naturally see the true thoughts in Chu Chen's heart, so he simply lay down on Chu Chen's shoulder and lifted Erlang's legs, "What's the trouble, it's right to find Uncle Ben." ”

"It's not my trouble, it's the eagle's trouble, it seems to have evolved to a bottleneck, no matter how much iron it eats, it can't evolve! ”

Once it came to the cultivation of his Black Eagle clone, Chu Chen didn't dare to be sloppy, and carefully explained the situation of the Black Eagle clone.

It's just that the more detailed Chu Chen said, the more surprised the little hamster's heart became. Its eyes widened, staring at him as if it had just met Chu Chen. This owner actually knows so much about that guy's situation, does he really accept it as a spirit? It's against the sky...... This kid is absolutely against the sky......

No matter how frightened he was in his heart, the little hamster pretended to be indifferent on the surface, and after listening to Chu Chen's description, he coughed slightly: "According to what you said, that golden wing...... The eagle is estimated to have successfully condensed the fine iron body. The next step is to go through the process of 'molting bones'. ”

"Molting bones?" Chu Chen frowned, "What do you mean?" "It's bone replacement." The little hamster pouted, "Goldwing...... That ** eagle is a desolate alien species, and after condensing the fine iron body, it means that its ** has reached the limit of mortal bones. If you want to evolve again, you must make the bones of the whole body get a metamorphosis and transform them into 'fairy bones'. ”
