3214。

Nangong Kexin, who had taken a bath, had just been lying on the bed for a long time, when she suddenly heard a knock on the door, and in confusion, she broke away from her hazy beautiful eyes, walked to the door and shouted through the door: "Who?" ”

She didn't know who was looking for her so late, so she didn't open the door directly.

"Kexin!"

"Yuchen?" Hearing that it was her younger brother's voice, Nangong Kexin opened the door, stretched out her head to look at Nangong Yuchen standing at the door and asked, "What's wrong?" ”

"That Kexin... Can I get in? Nangong Yuchen said with a somewhat unnatural face.

"Oh......"

Seeing that he was about to come in, Nangong Kexin didn't ask much, so she turned sideways, let him in, and closed the door.

After all, he was her own brother, so she didn't think too much about it.

After Nangong Yuchen entered the room, he glanced at the decoration inside, and found that this place was similar to his own room, but the layout was a little different.

And Nangong Kexin was only wearing pajamas because she had just taken a shower for a long time, so after letting Nangong Yuchen come in, she got into the quilt, looked at him with her head exposed, and wondered: "Yuchen... Is there anything wrong with you? ”

"It's nothing important..."Nangong Yuchen said this, and quickly smiled awkwardly: "I just want to ask you for a favor!" Haha..."

“… Help? Nangong Kexin saw that his younger brother looked a little strange, and couldn't help but be even more puzzled in his heart.

Because Nangong Yuchen in his sight, his expression and speech seemed to be embarrassed, and it was so late, he needed his own help? So what the hell is going on?

After living together for so many years, it was the first time she heard that Nangong Yuchen wanted to ask her to help.

"It's just... Kexin, can you help me break through to the second order..."

When the voice fell, Nangong Kexin glared at Meimu in some surprise and said, "Me? Help you break through to the second order? ”

As soon as he finished saying this, he felt Nangong Yuchen's gradually blazing gaze, and suddenly a pure little face turned red. Refused: "No... OK! Yuchen is so late... Go back quickly..."

She realized the meaning of Nangong Yuchen's words.

It's a pity that at this time, Nangong Yuchen had already walked towards her. "Sorry Kexin... I can only break through to the second order..."

"Nangong Yu... What do you want to do... I... I'm your sister! ”

Seeing Nangong Yuchen walking along the side of the bed, getting closer and closer to herself, Nangong Kexin instantly wrapped up the quilt, retreated to the bed and leaned against the wall, and stammered nervously: "You... You... Get me out... Ahh

The last sentence fell, and Nangong Yuchen had already climbed onto the bed and pressed it at the same time.

Seeing that she couldn't stop it, Nangong Kexin hurriedly shrunk her head into the quilt to prevent him from having a chance to suck his own blood. However, in terms of strength, she was too weak in front of Nangong Yuchen.

Soon the quilt was torn apart, and Nangong Kexin was completely exposed under Nangong Yuchen.

"South! Palace! Feather! Early morning! You... You dare to bite me, I... I'm going to kill you! ”

Nangong Kexin under her, looking at a face close at hand, suddenly blushed and hot, and under Nangong Yuchen's increasingly hot gaze, she felt that her whole body was soft and trembling!

"Whew!" Looking at his sister who was constantly struggling, Nangong Yuchen at this time was also red, but in order to break through to the second order, he could only choose to suck Nangong Kexin's blood again!

Thinking of this, after saying sorry guiltily, he directly ripped open the collar of Nangong Kexin's pajamas.

"Tear!"

Nangong Kexin, who couldn't move, watched his collar being torn open by him, and suddenly her beautiful eyes were full of tears, and while struggling violently, she trembled with extreme shyness: "Nangong Yuchen!" I... I'm going to kill you! ”

"You... Shut me up! ”

"You let go of me!"

"Woo... I... I'll kill you! ”

It's a pity that these bottomless threats are completely useless to Nangong Yuchen, because this is not the first time to hear her say this. And the snow-white and delicate fragrant shoulders and suo-bones in his sight, including the faint outline below, made Nangong Yuchen unable to hold back any longer, opened his mouth, and bit down.

"Poof!"

The sharp teeth that erupted, pierced the snow-white skin, and bit into it.

"Woo... It hurts! Nangong Yuchen, you... Bastard! I'm going to kill you..."

"Gollum!"

……

Gradually, Nangong Kexin's struggle became less and less, and at the same time, the scolding in his mouth turned into a soft moan.

Because at some point, the pain in my shoulder disappeared and was replaced by the same strange feeling of comfort as the last time......

A few minutes later, Nangong Yuchen got up, retreated under the bed, and looked at her beautiful and swollen sister on the bed with embarrassment and guilt.

"But... Happy... I'm sorry... I'll go back first! ”

Nangong Yuchen didn't dare to stay longer, so he quickly opened the door and slipped out.

And Nangong Kexin on the bed, her face was blushing, and she was lying on the bed soft, and she could only use her tearful eyes to stare angrily at the back of her younger brother leaving...

"Bang!"

After returning to his room, although Nangong Yuchen felt a little guilty about his sister, he was more excited in his heart!

This excitement comes from the excitement of gaining great strength in the body!

He could clearly feel that at this time, his body had finally broken through the shackles of the first order and truly entered the second order! Became a second-order demon! In the same way, according to Angel, her current body has also reached the second-order standard of human physical fitness!

Whether it is strength, speed, or the overall strength of the body, it is much stronger than half an hour ago!

If he meets Li Wei in the cake shop again, he has a strong self-confidence, even if he doesn't expose his speed, the neuroreflex-type mecha can easily solve him in just one minute, relying on the power-type mecha!

While clenching his fists and feeling the strength, a thick doubt suddenly rose in Nangong Yuchen's heart.

Why?

Why, after sucking my sister's blood many times, can I still get stronger?

If memory serves, this is the fourth time, right? The first time I sucked my sister's blood, I seemed to have broken through to the first order directly!

And the second time, his three physical abilities, under the test of Shangguan Mulong, directly skyrocketed to 150!

The third time, such as the battle outside the walls of Xia City, his physical energy was exhausted, and he was seriously injured at the same time, and after sucking his sister's blood, his physical strength and injury were completely recovered!

The fourth time, and this time, I broke through to the second order!

Why is that? Listen to Angel, her blood can only be used for the first time, so that her strength can be strengthened and her injuries will recover!

Truly! That night, after sucking her blood, all the injuries on his body recovered, and his strength also skyrocketed to the peak of the first order!

But except for the first time, she said that there was no effect later, so outside of the city wall, she rejected herself, and she rejected herself just now!

Nangong Yuchen could hear that Angel was not lying!

But it was because of this that he fell into a deep doubt at this time!

Why can I suck Kexin's blood many times to recover from my injuries, as well as become stronger and break through! And Angel's blood can't?

After a long time, he really couldn't figure it out, so he muttered to himself: "It seems that there is time to find Angel to ask all this clearly!" ”

After putting this matter aside for the time being, Nangong Yuchen took off his coat, lay on the bed, and thought about the next second-order mecha!

Five of the six mechs need to be upgraded, and the cannon sniper, because there is no way to upgrade, can only be replaced with a new second-order firearm!

In addition, after breaking through the second order, strength, speed, and nerve reflex have each increased one mecha, so I have to buy three more second-order mechas!

Nine mechs!

(Note: There are two pieces of the first order, three pieces of the second order, and four pieces of the third order, and after Nangong Yuchen breaks through to the second order, he can wear three more mechas!) One additional item for each of the three types! ）

How much does it cost?

After thinking about it, he suddenly found the biggest headache, that is, no money!

The five mechs of their own are upgraded to the second order, and the cannon sniper is replaced by the second order, which is worth a million to say the least!

And adding three more second-order mechas, it is estimated that it will be at least 1.5 million!

In this way, even if he breaks through to the second order now, the problem of the mecha will not be able to be solved in a short period of time! Without mechas, the combat effectiveness can't be enhanced too much!

……

"Whew!" The more Nangong Yuchen thought about it, the more he felt a headache, and finally he was too sleepy, so he closed his eyes and fell asleep.
