Quick time travel: The system wants me to save the sick girl

Lu Yan took a shower and went downstairs. Zhou Yixing was already at the dining table.

Auntie is fast and quickly prepared some simple food for them to fill their stomachs. The taste should not be bad.

Seeing Lu Yan come down and sit down, Zhou Yixing stood up and poured a glass of water for Lu Yan himself and came to his side. Then he leaned slightly and placed the water glass in front of Lu Yan.

"Thank you."

Lu Yan held the water glass, and Zhou Yixing made sure that there was no messy smell on Lu Yan's body out of Lu Yan's sight before he stood up and left.

Although Zhou Yixing's sudden intimate behavior was strange, it was not surprising when he thought of his high favorability.

After returning to the room at night, Lu Yan immediately found the system's knowledge points.

'System, please explain to me the issue of marking and the issue of estrus. What is a mark? I never heard you say that. '

System' Then I have to explain it to you carefully. I still can't explain it clearly in these two sentences. '

Lu Yan lay down on the bed, looking like he was listening.

'The first is the issue of marking. I will explain it to you from the perspective of alpha. The first is the issue of marking. This is divided into temporary marking and permanent marking. '

'Omega asks a familiar and trustworthy alpha to make a temporary mark during the estrus period, which can help the other person get through the estrus period. The temporary mark only requires biting the glands in the other person's neck and injecting pheromones. Glands are very private parts and not everyone can touch them. '

'The permanent mark is made by alpha or beta in the omega's reproductive cavity and is valid for life. If it is not through medical means, it is difficult to remove the permanent mark left by alpha on the opponent's body. '

'Host, once an omega is marked, other people's pheromones will have an oppressive effect on him, which will make the other person very uncomfortable. '

Lu Yan nodded and recalled the very strong pheromones he smelled in the bathroom. "Then why was the pheromones I smelled so strong before?"

"Because the other party was in a fever period at the time. Omega has a fever period once a month, while alpha has a susceptible period once every three months, which lasts about three to five days."

"When the pheromone concentration is at a standard level, it constitutes induced attraction, which requires the use of means to eliminate, such as injecting inhibitors. When it is high, it is accompanied by pressure in addition to attraction induction, so when the alpha concentration is too high, it will produce pressure, just like your first I felt the same when I saw Zhou Yixing."

Lu Yan nodded. He did feel oppressed when he saw Zhou Yixing. He thought it was because of the other person's temperament, but he didn't expect that it was also due to pheromones.

"So host, you must control your pheromones at ordinary times. Once you mark an omega, you must be responsible for the other person, otherwise you will be a scumbag."

Lu Yan was ashamed. Is he the kind of irresponsible person?

"The other thing is the issue of estrus. In this world, except alpha, beta and omega are all capable of pregnancy, but beta's fertility is lower than omega."

"There is also such a thing, doesn't that include male omegas..."

"Yes, host, it's what you think."

Lu Yan got up early the next morning. Maybe it was because he heard the system's bold speech yesterday, which caused him to sleep uneasily.

And when he woke up in the morning, he felt something was wrong with his body, that is, his pheromones felt a little out of control.

But he recovered quickly. In just a few minutes, Lu Yan put on a barrier patch just in case, and took the inhibitor before going downstairs.

Today, Zhou Yixing's friend made an appointment with the two of them to play badminton. The appointment was made before Zhou Yixing went on a business trip, so he couldn't shirk it.

So Lu Yan couldn't be absent. Anyway, he felt pretty good. The only discomfort was only for a few minutes in the morning, so he went with him.

Lu Yan went down the stairs and Zhou Yixing was already at the dining table.

Lu Yan sat down opposite him and said, "Good morning."

"Yeah." A cold voice said.

Lu Yan raised his head and looked over. His originally tied hair fell down. Lu Yan asked tentatively, "Lu Xiangheng?"

Lu Xiangheng looked at Lu Yan and said, "Call me brother."

"Brother." The cold tone made Lu Yan change his mind immediately. The three of them didn't know what the other had done, so even if Zhou Yixing was interested in him, Lu Xiangheng didn't know.

Lu Xiangheng only regarded Lu Yan as his brother.

Lu Yan finished his breakfast in silence, which was very depressing. He was used to getting along with Zhou Yixing, and suddenly Lu Xiangheng came out.

It's only been a day, why have they changed people?

'They won't always switch so frequently. ' Lu Yan thought to himself.

System' who knows. '

Lu Yan had never been to the place where we made the appointment this time, so he could just follow Lu Xiangheng.

'It's quite novel that there are still people asking to play badminton. Shouldn't these people be more interested in playing golf? ' Lu Yan thought to himself.

There was no one in the badminton court. It must have been cleared. There were a few people inside who had changed into sportswear. When they saw Lu Xiangheng and the others walking in, they said hello from afar.

Lu Xiangheng raised his hand to signal.

"Go change clothes." Lu Xiangheng said to Lu Yan.

Lu Yan nodded, "Let's go."

The changing room was not big, so they both changed in the same room. Lu Yan's back was turned to Lu Xiangheng and he didn't notice anything wrong.

But Lu Xiangheng could see Lu Yan in the mirror in front of him.

Originally he wanted to look away, but when Lu Yan took off his shirt and exposed his back, he couldn't take his eyes away. From this angle, he could see the barrier sticker hidden under the hair, which was the location of the glands.

Lu Xiangheng thought to himself, 'Not like an alpha at all. '

Then he quickly changed his clothes and walked out with Lu Yan.

They seemed to be competing, so Lu Yan and Lu Xiang went to the side to warm up and play against each other.

Lu Xiangheng's skills were very good, and Lu Yan's was not bad either. They barely managed a tie. Lu Yan subconsciously pulled up the hem of his clothes to wipe his sweat, exposing his abdominal muscles.

His abdominal muscles are like natural gemstones, with clear lines and as smooth as jade. Every rise and fall is full of strength and beauty.

This move directly caused the people next to him to scream uncontrollably.

Lu Yan looked over and saw that they were the administrators of the stadium. Although they all looked male, Lu Yan still couldn't tell their gender.

Lu Xiangheng also saw Lu Yan's actions and was inexplicably dissatisfied. He took a towel and threw it over and said, "Wipe it off."

Lu Yan took it, "Okay, thank you, brother."

Lu Xiangheng turned around and left, and then Lu Yan walked over and met the man who invited them to play ball.
