Lucy was getting happier and happier, but she seemed to have sensed something and a pitiful look appeared in her eyes.

Ye Feng's heart jumped, she could feel that he was about to leave, but he believed that she would be worried about her as well. He wouldn't stay for long after he returned home, so she thought a bit too much.

"Why do you need so much energy to become invisible? "Can you control it a bit?" Ye Feng asked.

Lucy did not know how to control her, her ability seemed to be an inborn ability, so towards Ye Feng's words, she suddenly did not know what to do, her comprehension ability was also very limited, Ye Feng's explanation was complicated, and she could not understand either, causing Ye Feng to feel troubled.

He felt that she was somewhat lacking in beauty. If she could last for a little longer, or not be so tired that she wanted to sleep, then he was confident that he could bring her out and let her arrow the world outside.

"Come, let me see." Ye Feng felt that he also had some power, and laughed as he extended his hands towards her little hands and grabbed them.

Lucy simply did not understand what her brother was trying to do, and was obedient as he wished.

Ye Feng closed his eyes, and an image slowly formed in his mind!

The special scene in Ye Feng's mind clearly displayed the structure of her body, and there were even some special things. His entire body shook, maybe she really was fourth type!

One must know that Ye Feng had already directly entered the third type just now. He did not expect Lucy to directly enter the fourth type after being injected with gene medicine, but since this was a secret, no one else would know about it. This made him feel slightly comforted in his heart.

He was the only one who knew the secret. As long as he didn't say anything, no one would understand. The researchers had only classified her as the second type now.

How did Ye Feng know? It was because he discovered that the energy circulation and circulation inside this girl's body were the same as his, but there was clearly a difference between her and himself. The energy that she absorbed existed less in this space, he did not understand why that was the case.

As Lucy continued to grow, her state of mind would also slowly fade. In time, she would definitely become an outstanding fourth type expert!

After all, she looked like an adult right now, but in reality, her mind was still a child's brain. If her mind was mature enough and knew some absorption methods, maybe she would become a super abnormal person by then, Ye Feng thought. This was what Ye Feng had thought.

After all, she trusted the man in front of her the most, so she was not embarrassed in the slightest. She quietly looked at him, not understanding why Big Brother would do such a thing to her.

Ye Feng thought for a bit, and felt that he should have a way to improve on this. He only needed to teach her his own methods, and as long as he built an instinctive absorption technique in her body, she would definitely be able to remain invisible for a better period of time than before.

This discovery made him extremely happy. This was probably the best method in a short period of time.

Seeing her brother open his eyes, Lucy wanted to ask, but didn't know what to say.

"Are you going to listen to your brother?" Ye Feng asked.

Lucy nodded, naturally she had to listen to him, here she only had him to rely on.

Ye Feng thought for a while, and felt that he should give it a try. After all, it was quite pitiful for this girl to become like this. As long as she had enough energy, she wouldn't be in a state where she was tired and wanted to sleep.

Ye Feng nodded: "Close your eyes, be good."

Did he want to kiss her or was he trying to do something bad by closing his eyes? This thought appeared in Lucy's heart, and even she felt that it was strange that she did not think about it, nor did she ever think about why such a thought would appear.

"Carefully feel something in your body." Ye Feng held onto her small hand, allowing him to feel some of the restlessness within his body.

Lucy slowly found out that she was not stupid at all, so she also tried to follow Ye Feng's guidance and slowly experienced the mysterious feeling of the particles roaming in her body.

Ye Feng was also extremely shocked by her talent. If she was allowed to grow up successfully, then his mind would be much smarter than ordinary people. This was merely a simple instruction from himself, and she would be able to find it accurately.

It seemed that this girl could really be saved. He decided to stay here for a period of time, and if he had the chance, he would bring her out. Even if he released her, he could guarantee her safe return.

Of course, all of these things required her to work hard on her own. She had to work hard to make herself stronger, and the energy would have to meet some of the needs she had to go out with.

Lucy slowly leaned on Ye Feng's guidance, and continuously absorbed the strange energy within the space.

When Ye Feng saw that during the process of her absorption, his body would actually emit faint rays of silver light, which further confirmed that she was using fourth type as proof!

"That's all. How do you feel?" Ye Feng asked her.

When Lucy mastered this method, she was especially happy. She felt that her body was much stronger than usual, and her heartbeat used to be very fast whenever she walked, let alone when she used her ability.

If she followed this method, she would definitely not be sleepy for a short period of time, and she would even be stronger.

"Listen to me." Ye Feng laughed and said: "Just continue practicing like this, the faster the better. Once your strength has grown, I will bring you out for a walk, and not let those people discover you, understand?"

's eyes revealed a strong desire. Going out was something she really wanted, but hearing Ye Feng say that she had the chance to do so, that desire was even stronger than anything.

This time, she was determined to get out as soon as possible. Otherwise, if her brother left, she wouldn't be able to do anything.

She was wrong in her understanding of the situation. Ye Feng had brought him out for a stroll and not to bring her away, she had to stay here forever and Ye Feng could not stay either. After all, he knew her here, and this was her wrong idea.

The first day, Ye Feng taught her a few things.

The second day!

This also meant that her energy was increasing more and more in her body, and the speed of the cells that were splitting up was also increasing, it was exactly the same as's body. If not for Lei Ao's pressure, which allowed him to break through to the fourth type, he wouldn't have noticed this special change.

Time slowly passed, and Ye Feng went to look for Xiao Ya a few times. This girl's life was also getting better and better, she just came back and continuously watched Lucy practice.

But very quickly, he discovered the changes on Lucy's body. She had an even more bewitching ability, and her hair had astonishingly changed as well. Why was that so?

He was not a scientist, and for some reason, her hair grew longer and longer until it almost reached her buttocks. Furthermore, the white spots could be freely converted into black!

The black haired Lucy was very different from normal people. As an Oriental, Ye Feng liked black hair even more. The current Lucy gave him a feeling that he was about to run a horse whenever he looked at him, and his own lower body had unknowingly become tough as well. This idea was very scary to him.

"Big brother …" Lucy watched as Ye Feng walked in and then grabbed his own hair, and was a little curious as to why he would undergo such a change.

Ye Feng had thought about her hair, probably because there was not enough energy in her body to support her needs, but also because her hair had a type of ability that needed to be absorbed. He observed that under the state of Internal Inspection, her hair absorbed the most energy, so every time she lost energy, her hair would turn completely white.

She looked at herself with teary eyes, as though she had changed. She didn't know if Ye Feng would still like her, and Ye Feng was able to see through her thoughts.

"Did you see that?" Ye Feng pointed to his hair and asked.

Lucy nodded, it was black indeed.

"We all have black hair, and your brother and I love black the most. Right now, you are even more beautiful than when your hair was white." Ye Feng comforted her. This was indeed not a problem, she did have the ability to change back.

Hearing Ye Feng's explanation, Lucy beamed with happiness, and no longer had any misgivings.

"Come, let your brother see how much your ability has improved." Ye Feng rubbed her head and asked.

Lucy slowly raised her head, looked into his eyes, and then slowly turned around, her black hair fluttering in the wind.

Ye Feng didn't even dare to look. He was afraid that he wouldn't be able to take it any longer, so he directly pounced towards her and seized her for himself.

Lucy didn't put any guard around him, and very quickly, her hair started to turn white, and slowly her body disappeared into the air, in just a second!

Although it was only for a second, Ye Feng was still very surprised at her progress. It was completely invisible, he could not even see what was wrong with his, he finally had some experience how strong this girl was.

After her stealth state had been confirmed, there were still some faint shadows, but that second of complete disappearance was a testament that she had enormous potential.

Furthermore, Ye Feng had subsequently discovered that she did not seem to be exhausted after Lucy had changed back to her usual self. Her hair was also alternating between black and white, which made his feel that it was very strange.
