When a weak bamboo horse differentiates into the strongest A

To this day, Zhong Chuchu still hasn't figured out what is going on with his growing possessiveness towards Luo Xing.

The physiology lecturer said that it is normal for AO pheromones to have mutual attraction, but he does not think that he is completely influenced by pheromones.

Because he had a strong consciousness when he was very young - he didn't want to differentiate himself into the same gender as Luo Xing.

It's a pity that God made fun of him with a false shot.

Luo Xing at the side had no idea what dangerous things the people around him were thinking.

After the meeting adjourned, he grabbed Zhong Chuchu and began to babble about his impressions, especially the temporary marks mentioned by the lecturer.

When Omega is temporarily marked, the spirit will be in an indescribably wonderful state for a short time.

He knew a lot of people at school, and many friends who had puppy love around him revealed to him that the feeling of being bitten on the back of the neck is [-] times better than kissing and smoking.

He has always been curious about this, especially after being proved by professionals just now.

Luo Xing touched his neck, the skin there was very smooth and there was no trace of glands at all. He found the approximate location according to the method taught by the lecturer, and pressed it, but he didn't feel anything.

"Brother, what do you think it feels like to be bitten on the back of the neck?"

"do not know."

"Did you listen to what the physiology lecturer said? It seems that you will fall into a strange state, and I am suddenly interested."

Zhong Chuchu frowned, and said in a deep voice, "You're only so old, don't be interested."

Suddenly offended by Zhong Chuchu, Luo Xing curled his lips: "You look very much like my dad now."

However, Zhong Chuchu's words didn't have much of a deterrent effect on Luo Xing, he still kept talking to his brother about how he felt about the "temporary mark".

When the two returned to class, the classroom was still empty.

After Zhong Chu sat down, he pinched the center of his brows, and looked out the window, obviously not in a good mood and didn't want to talk to Luo Xing.

Luo Xing ate a rice cracker, saw that Zhong Chuchu was still looking at the scenery, and asked jokingly, "School grass, are you really not curious at all?"

Luo Xing felt that his brother's heart was as calm as water, he was about to become a Buddha immediately, and he didn't have any minor turmoil that should be in adolescence.

"Anyway, no one sees us in this corner, why don't you bite me."

Zhong Chuchu was annoyed by Luo Xing's noise, he turned his head, and what caught his eye was the part of his neck deliberately exposed on the collar of his dark brown sweater.

Almost blindingly white.

Zhong Chuchu's Adam's apple twitched: "Are you sure?"

Luo Xing nodded frantically: "Bite it, bite it, it's all Omega, and my neck has been washed for nothing, it's very clean!"

As he spoke, he took the initiative to move closer, exposing the entire back of his neck to Zhong Chu's eyes unsuspectingly.

In an instant, Zhong Chuchu felt a terrible physical impulse, but fortunately, reason gave him a few seconds to think.

The S-level Alpha's differentiation process can only be marked when it is pushed to [-]%, and his current state is like a kid who has just differentiated in the first year of junior high school, and it is impossible to mark any Omega.

So, a bite is fine.

If he doesn't bite today, he can't guarantee that Luo Xing, a skinny monkey, won't find someone else to bite him out of curiosity...

He must not allow such a thing to happen, even if the other party is an Omega.

Luo Xing opened his eyes wide and looked at Zhong Chuchu without blinking, as if he was letting you taste it. He firmly believed that his brother would not have the heart to refuse him such a small request.

Zhong Chuchu finally gave Luo Xing ten seconds to repent, and in the next second, he bit down on that delicate inch of skin.

The moment the pheromone-laden saliva seeped into the glandular skin, Luo Xing's whole body was crisp from skin to bone.

He felt like he had jumped onto a soft cloud, and he couldn't help sinking down, and was being supported all the time, making it impossible for him to really fall.

The strong mint smell enveloped him continuously, and it was a little different from what he had smelled before——

It was obviously the coolest and most refreshing smell, but it was as hot as fire, covering the sky and covering the sky, making him unable to breathe normally for a while, and could only surrender without resistance.

He even forgot what he was doing, he only remembered that the person holding his waist tightly was his brother, Zhong Chuu.

In the corner of the classroom where no one was paying attention, the big hand supporting Luo Xing's neck tightened a bit.

This is definitely the sweetest taste Zhong Chu has tasted in 18 years.

But in the end, his rationality still prevented him from continuing to force his teeth, and he just used his tongue to lick that inch of skin that smelled like green plums.

But in just a few seconds, Luo Xing collapsed onto Zhong Chuchu's body, gasped in Zhong Chuchu's ear uncontrollably, and finally moaned like a kitten, scratching his paw faintly with lust. Entering Zhong Chuchu's heart, his little brother was startled.

It seemed as if a century had passed before Zhong Chu forcibly let Luo Xing go.

The two woke up like a dream.

Zhong Chu's chest rose and fell, a few strands of hair hung down his forehead, and the expression on his face was a bit like a handsome vampire who had just sucked blood.

With her blushing cheeks on her face, Luo Xing muttered, "It turns out that being bitten on the back of the neck feels so cool."

Zhong Chuchu: "..."

is it cool?Zhong Chu frowned. He seemed to smell something that didn't belong to Luo Xing on Luo Xing.

Sure enough, half a minute later, Luo Xing nervously opened his psychology notebook.

"Temporary markings are characterized by... short-term swelling of the glands, rapid heartbeat, body temperature, body temperature..." Luo Xing's voice trembled a little after he read it.

"And absorb the Alpha pheromone until the smell is fused, and the temporary mark can last up to 12 hours." Zhong Chuchu added in a deep voice that Luo Xing didn't write it down.

Compared to Luo Xing's astonishment, Zhong Chuchu was actually even worse, but it didn't show on his face.

He most likely marked Luo Xing.

In other words, to this day, he has actually completed his differentiation, officially becoming the rarest S-level Alpha.

Luo Xing was still flipping through the notes, his heart pounding all the way to his throat, and then he was pounded hard by the things he had memorized, and soon he was half-cooled.

He was really a little confused, and he couldn't judge what happened for a while.

Isn't Zhong Chuan an Omega?

Why did he react after being temporarily marked by Alpha?

What exactly is Zhongchu?

Is it just an illusion?

……

Luo Xing thought indiscriminately, and quickly turned a dozen questions into a mess. He raised his head to seek Zhong Chuu's help, but suddenly bumped into Zhong Chuu's eyes with complicated expressions.

He retracted his gaze as if he had been burned.

Damn, the mess is even more messy!

3 minutes later--

With an extremely pious heart, Luo Xing greeted all the gods and gods from all walks of life, and then he was heartbroken, closed his eyes and raised his wrist to smell himself...

He opened his eyes suddenly, and his eyes were bigger than the copper bell.

Greengage mint.

"Damn, I'm so confused... Zhong Chuu, you bastard, big liar!!!"
