D-level males reached the pinnacle of life by living off women.

Lu Yuan opened the first page of the textbook and began to read it carefully. He had only glanced at it briefly before and had long forgotten what it contained.

The textbook begins with a long introduction that provides a detailed description of the origins of spiritual comfort.

Long ago, the universe inhabited by the Zerg was not dominated by the Zerg alone, but by multiple intelligent races. Moreover, the Zerg were very weak at that time and were in a backward and vulnerable position among the various intelligent races.

To ensure the continuation of their race, the female insects were the first to evolve a spiritual sea, which granted them unparalleled power, giving the insect race an advantage in competition with other races.

However, the Zerg were not happy for long. Everything has its advantages and disadvantages, and the Spirit Sea was no exception.

Soon, the Zerg discovered that the female Zerg that had evolved a mental sea would experience unbearable pain every so often. Moreover, as the frequency of the pain increased, the lifespan of the female Zerg also decreased.

Moreover, the stronger the female insect, the more intense the pain and the faster its lifespan is shortened.

The Zerg exhausted every means to find the cause of all this. Finally, research proved that the unbearable pain and reduced lifespan were due to the mental sea.

Each time the female insect uses those unparalleled powerful forces, it depletes her spiritual sea, causing cracks to appear in it.

When cracks accumulate to a certain extent, they will erupt into unbearable pain, which is now commonly known as a mental breakdown.

When the cracks accumulate to the point of mental collapse, the female insect's life will also perish.

The Zerg, having discovered the cause, were nearly in despair, for they had tried everything but could not find anything that could repair the cracks in their mental sea.

Fortunately, the Zerg were not abandoned. After a period of time, the male Zerg also evolved.

The male insect has evolved mental power, which allows it to release mental power tentacles. These tentacles can enter the female insect's mental sea and help repair the cracks within it.

However, male insects evolved much later than female insects, so most male insects are of a lower level than female insects. In practice, it has been proven that low-level male insects do not have enough mental power to effectively soothe the mental sea of ​​high-level female insects.

This also meant that in the early stages of evolution, many high-level, powerful female insects were unable to receive mental comfort.

However, high-level females are the most important fighting force of the Zerg. In order to allow more high-level females to obtain mental power...

Through the efforts of a generation of Zerg, the Zerg have compiled this textbook.

Lower-ranking male insects can train and improve their mental strength according to the methods in the textbook in order to appease the mental sea of ​​higher-ranking female insects.

After reading the whole thing, Lu Yuan felt that the logic was quite smooth and the textbook seemed to make sense. Moreover, he seemed to have seen some insects mention the fact that most male insects were of low rank in that forum before.

Lu Yuan decided that he would try to train according to the method in the textbook, betting on that one in ten thousand chance. If he succeeded, Rhine would not have to suffer when the mental sea rioted in the future.

Of course, this matter should be kept from Rhine for now. It's obvious to anyone that if Rhine were told, he would definitely not agree.

After that, Lu Yuan adjusted his daily routine. Every morning when he got up, he would go outside to run and meditate while Rhine was still asleep.

The textbook states that mental calming is a very physically demanding task, so the male insect must first have a healthy body.

When Rhine is about to wake up around noon, Lu Yuan will go home. He will spend the afternoon at home with Rhine, as they are still in the honeymoon phase. While it is important to train their mental strength, they can't neglect their relationship.

After Rhine went to work, Lu Yuan released his mental energy tentacles and trained them according to the methods in the textbook. After training for five hours, Lu Yuan went to sleep and got up again in the early morning to pick Rhine up from get off work.

The days passed in this cycle for more than three months. At first glance, Lu Yuan's mental tentacles didn't seem to have changed much; they were still only the thickness of a straw. However, he didn't get discouraged and continued to work hard.

In fact, Lu Yuan did not notice that although the thickness of his spiritual tendrils had not changed, their color had become much more solid. They were previously light blue and almost transparent, but now they were no longer transparent.

Inside the Mande Auction House.

Following his superior's instructions, Rhein and a colleague threw a troublemaking customer out of the house, beat him up as per procedure, and also took a wallet from him.

Upon opening it, I was surprised to find it was a lucrative opportunity, containing a thousand star coins.

Rhine took out the Star Coins and gave 500 Star Coins to her colleague next to her, who accepted them with a smile.

Rhine checked the time; it was already 2 a.m. She could get off work in another hour. Thinking about seeing Lu Yuan in just one hour, Rhine couldn't help but smile.

"Rhine, you're laughing like that, you must be thinking about your male master again. But your male master is really good to you, he actually comes to pick you up from get off work every day. I've never seen a male insect take such good care of a female insect before," a colleague teased.

Hearing his colleague praising the long distance, Rhein's smile became even more genuine.

"By the way, Rhine, could you do me a favor?" the colleague pleaded, clasping his hands together.

"Tell me, is there anything I can do to help?"

"I have some things to take care of and want to leave early today, but I don't want my wages to be docked. Could you help me cover it up so the team leader doesn't find out?"

"No problem, go ahead. The rest is just patrolling, it's simple. I'm fine with a bug, the captain won't notice you're not here."

"Thank you so much. They're right, you're such a good worm," the colleague said gratefully.

"You're welcome. Just don't refuse if I need your help in the future," Rhine said meaningfully.

"Don't worry about that. If you ever need my help in the future, just tell me, and I definitely won't refuse," my colleague assured me, patting his chest.

Since Rhine had agreed to help cover it up, his colleague naturally left with peace of mind.

After his colleagues left, Rhine turned and continued walking forward, beginning his patrol alone.

Halfway there, Rhine suddenly felt a needle-like pain all over his body. Although the pain only lasted for a few minutes before it disappeared, Rhine knew exactly what it meant: his mental sea was about to erupt.

His mind has never sought solace from male insects, and the pain during each rampage is escalating. This time, he may lose consciousness from the pain.

In order not to harm Lu Yuan, he needed to make preparations in advance.
