By the time Chu Yun and Zhan Cangqiong returned to the ground, it was already dark.

Chu Yun hastily ate dinner, then returned to his room, took out the black ability crystal he took from the ability crystal library today, and carefully observed it for a while.

The pitch-black crystal actually emitted a faint glow in the pitch-black room, which looked particularly weird.

Majestic energy gushed out from the black crystal.

Now the ability crystal is available, but how to absorb the energy on the ability crystal has become a new problem, bothering Chu Yun.

He had only heard from Fang Lan that he could improve his ability by devouring the energy on the ability crystal, but Fang Lan didn't tell him how to absorb the energy on the ability crystal.

Chu Yun, who was distressed, held the ability crystal and thought it carefully.

Suddenly, Chu Yun thought of the ancient martial arts he cultivated, and the cultivation of the internal strength of the ancient martial arts was through tempering the spiritual energy between heaven and earth, slowly refining the spiritual energy, and turning it into his own internal force.

So, with the mentality of giving it a try, Chu Yun was the guide to the supernatural energy in his own body, and then tried to channel the energy on the black crystal into his own body.

However, Chu Yun tried four or five times in a row, and the ability crystal released majestic energy, but Chu Yun just couldn't introduce that energy into his body.

Chu Yun was not a person who was willing to fail, and after several unsuccessful attempts, Chu Yun did not give up, but continued to guide the energy in his body to devour the energy on the crystal.

After a long time of experiments, a faint trace of energy finally poured into Chu Yun's body, and under the wrapping of the energy mass in Chu Yun's body itself, it slowly merged into that energy group.

Seeing this, Chu Yun was overjoyed, and hurriedly increased the energy contained in the black crystal.

Streams of surging energy poured into Chu Yun's body, spinning rapidly in Chu Yun's body, slowly merging into the abnormal energy core in Chu Yun's body.

However, as time went by, Chu Yun also discovered something wrong.

It turned out that the abnormal energy core in Chu Yun's body was a golden lightning abnormal energy core, flashing with thunder and lightning arcs on three sides.

However, with the influx of the energy of this black crystal, the pitch-black energy gradually surrounded Chu Yun's original golden thunder and lightning.

Then the golden core turned gray, and was eventually completely impregnated with the black energy emitted by the black crystal.

On this side, how could it not make Chu Yun's heart frightened, Chu Yun secretly thought in his heart, could it be that this black crystal was some kind of poisonous crystal.

So, Chu Yun hurriedly stopped devouring the energy on the black energy crystal, but this black crystal seemed to be adsorbed on Chu Yun's body, no matter how hard Chu Yun tried, he couldn't stop the majestic black energy from pouring into his body.

Seeing this kind of scene, Chu Yun was directly taken aback, and secretly thought in his heart, it's bad.

However, in the face of such a situation, Chu Yun was powerless at all, only to see streams of black energy pouring into Chu Yun's body, integrating into Chu Yun's blood and bone marrow.

Slowly, Chu Yun's whole person also turned pitch black, and even the scarlet flesh and blood also turned into black like carbon.

Moreover, Chu Yun's body also became extremely uncomfortable, the qi and blood in his body were churning, and the surging energy was like a tide, constantly rolling and colliding in his body, and his whole body seemed to be about to explode.

Streams of unprecedented severe pain swept through Chu Yun's body.

Faced with such a situation, Chu Yun didn't dare to slack off in the slightest, endured the severe pain coming from all over his body, and hurriedly activated the internal force in his body, protecting his heart and stabilizing his mind.

Chu Yun knew that he had to grit his teeth and persevere, otherwise, he would most likely die.

"Huhuhu!" Chu Yun gasped more and more urgently, more and more urgently, and his mouth was open, like a blower, where he was inhaling heavily.

At the same time, the burning pain in his body stimulated him, causing his muscles to bulge, and beads of sweat the size of beans kept rolling down Chu Yun's body.

Chu Yun felt that his consciousness was getting more and more blurred, more and more blurred, and his eyelids were getting heavier and heavier, just when Chu Yun was about to be completely unable to hold on, the energy on that black crystal was finally swallowed up by Chu Yun.

Moreover, in a daze, Chu Yun felt that the pink watch in his hand actually emitted a white soft light, enveloping Chu Yun in it.

The soft light entered Chu Yun's body, like a sweet spring, flowing into the thirsty field, moistening and the field, and the burning sensation on Chu Yun's body also slowly dissipated, and finally slowly turned into calm, and Chu Yun also completely fainted.

When Chu Yun woke up again, it was already the early morning of the second day, and the sun was already rising high.

At this moment, Chu Yun's whole body, not only did he not feel the slightest discomfort, but he felt refreshed and energetic, as if there was a surging energy in his body.

Through the mirror beside the bed, Chu Yun carefully looked at his dignity at the moment, and found that his body was now back to normal color, no longer like last night, shrouded in black energy, and his whole body was pitch black.

Suddenly, Chu Yun saw the pink watch in his hand, and at this moment, Chu Yun didn't have the slightest sense of disobedience when he looked at this pink watch, but kissed his watch a few times.

Chu Yun knew that last night, if it wasn't for the white light released from this watch, Chu Yun might have gone to report to Lord Yama.

What Chu Yun never expected was that this undeniably looking watch actually had this kind of function.

Unconsciously, Chu Yun actually dragged his watch and praised it: "Watch, you are so cute, I just love you to death!"

"Thank you, master, for the compliment!" I saw in front of Chu Yun's eyes, in a white light and shadow, a beautiful girl wearing a mini skirt said with a shy look.

Seeing this kind of scene, the surprise in Chu Yun's heart was simply indescribable, the long mouth was simply able to swallow an egg, he really didn't expect that in today's society, there would be such a magical high tech.

"Are you?" asked Chu Yun cautiously.

"I'm your watch, Min'er, is there anything I need to do for you?" replied the girl in the light curtain.

At this moment, Chu Yun revealed his signature movement again, stretched out his hand, and clasped the back of his head stupidly.

"What, can you tell me how to unlock this watch?" Chu Yun asked.

"Woo woo, doesn't the master like Min'er and wants to discard Min'er?" said the girl in the light curtain with a sad look.

"No, no!" Chu Yun hurriedly said, Chu Yun's life, the most unsightly thing in Chu Yun's life is the girl's crying, so he hurriedly said.

"Then why did the master untie Min'er?" said the girl with wide eyes.

"It's just, it's just that your color is pink, and you know, I'm a big man after all, and the pink watch is always a little twisted, so..."

"Oh, this one, it's simple, my surface is made of replicable nano materials, and it can be transformed into any style and color at will!" the girl said cheerfully.

"Really?" Chu Yun asked with some suspicion.

"Really, we have black classics, business elites, small jasper, crazy domineering, fashionable, ••••••!" The girl said a series of more than a dozen styles for Chu Yun to choose.

Chu Yun carefully observed those styles, although they were all extremely good-looking, but Chu Yun was not satisfied, he wanted to create a form that belonged to him, so he asked, "Can I customize my own style?"

"Yes!" replied affirmatively, "As long as the master gives me a model, I can transform it immediately!"

Hearing this reply, Chu Yun secretly rejoiced in his heart, and quickly took out his Heaven Killing Knife and said, "Just make me like this!"

"It's easy!" the girl said with a chuckle.

Then I saw a flash of light, and the original pink, old-fashioned electronic watch instantly became a fashionable watch with the appearance of a sky-killing knife.

"Master, are you satisfied?" the girl asked respectfully.

"Satisfied, satisfied!" Chu Yun quickly nodded and said.

"Chu Yun, you shrunken turtle, if you have a kind of you, you will come out to the master, the master will try to find you today to see whose strength is stronger!" Just when Chu Yun was immersed in experiencing the various functions of the watch, an extremely discordant voice sounded.

For such a thing, Chu Yun didn't bother to pay attention to it, and let the stupid man outside make a noise, his own people were exploring the function of this watch.

Not to mention, this watch developed by Lao Qi can be said to be a real god, and its functions are so powerful that it is simply beyond Chu Yun's imagination, it is simply an all-round assistant, no matter what, causing Chu Yun to secretly rejoice, he really picked up a treasure this time.
