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

Considering Lu Yuan's status as a D-level male insect, Rhine felt that Lu Yuan must be unwilling to accept that his mental strength was so weak, which was why he asked this question.

That's normal, since mental strength represents everything for male insects. However, he couldn't comfort Lu Yuan about this, so he could only tell the truth.

"I've never heard of a way to improve mental strength. The mental strength of a male insect is fixed from the moment its level is determined."

Lu Yuan wasn't too disappointed. This was exactly what he expected; that lousy textbook was indeed a scam.

Lu Yuan didn't pay much attention, but Rhein thought about it and felt it was a bit strange. Lu Yuan had never paid attention to his mental strength before, so why would he suddenly ask about it now? Then, he had a guess.

"Master, you didn't happen to hear that story about the male insect's rise to power, did you?"

"What story?"

Rhine told Lu Yuan that decades ago, a novel about a male insect's counterattack and face-slapping appeared on the market. It was about a D-class male insect who, although born into a noble family on the capital planet, was looked down upon by all insects because of his low rank.

Not only did the house insects look down on him, but even the servant insects in the house looked down on him. Later, he was even dumped by his own A-rank unmarried female insect. After the breakup, this male insect was banished by his family to a remote planet.

Then the story of his comeback begins. This male insect has a series of adventures on a remote planet, and his mental strength actually skyrockets from D-level to S-level.

Then comes the face-slapping scene: the S-class male insect returns to the capital planet and slaps the faces of all the insects that looked down on him and bullied him. Anyone who had ever done anything bad to him met a terrible end.

Among them are various high-ranking female insects, such as S-class, SS-class, and SSS-class, who express their affection for male insects and lick them in various ways.

In the end, this male insect married the most revered female insect prince of the empire as his queen, and other high-ranking female insects who were fond of him became his female servants. Several lower-ranking female insects also cried and begged to marry the male insect, and the male insect reluctantly took them in as his female slaves.

In the end, the male insect ascended to the throne and became the insect king, living a shameless life with his female insects in the palace every day.

This novel was a sensation among the Zerg at the time, and many low-level male Zerg thought that the methods for improving mental strength in the book might be real. At that time, many textbooks on improving the mental strength of male Zerg appeared on the market, and many male Zerg bought them.

Later, even the Xiongbao Association was mobilized to find the author of the novel and to find out whether the methods for enhancing mental strength described in the book were really based on fact.

"And then, is it true?"

Lu Yuan's eyes lit up as he asked with great interest. Sure enough, the kind of satisfying plot of a comeback and face-slapping is popular in every world.

"Of course it's fake."

The Xiongbao Association later discovered that the novel was a figment of a C-grade male insect's imagination, and all the plots in the novel had no factual basis. The so-called teaching materials were also fabricated to swindle money.

After that, the trend of enhancing mental strength gradually subsided.

"So, my lord, you didn't hear about this novel somewhere and believe in those methods for enhancing mental strength, did you?" Rhine looked at Lu Yuan with suspicion.

"Ahem, no, no, I just suddenly thought of it and was just asking casually."

Lu Yuan decided not to tell Rhein about the textbook. He felt that the textbook was probably something made up to scam money when the novel was popular, and that he would make himself look stupid for picking it up.

That textbook can stay under the mattress forever.

......

After Rhine's leg healed, the female insects in the junkyard dared not provoke them even more.

The days that followed were peaceful and uneventful, with each day consisting of picking up trash, selling it, buying things, and saving money. However, Lu Yuan and Rhine's little home underwent quite a few changes.

First of all, their house became bigger, from a wooden house with only one room to a wooden house with two bedrooms and a living room.

Although the house's exterior was still indescribable, at least the space had become larger, and after such a long time of travel, Lu Yuan finally had his own room and his own bed.

However, this wooden house was not built by the two insects through hard work, but was purchased for free.

At first, Lu Yuan and Rhine were talking about the future. He told Rhine that he wanted to rebuild the house after saving enough money, because the current house was too small.

Then the next day, they had a new house, which Rhine had snatched back from the other female insects.

When Lu Yuan found out, his jaw almost dropped in shock. But the other female insects in the junkyard acted as if it were perfectly normal. Even the female insect that was robbed didn't complain. Instead, she went on to rob other female insects' houses.

This is the survival rule here at the landfill: if you want something, just rob it; if you're capable of robbing it, it's yours.

Lu Yuan, of course, wouldn't have a moment of saintly compassion and accuse Rhine of doing such a thing. After his initial surprise, he quickly accepted his new home.

Secondly, their family's diet has finally changed a bit; they no longer drink nutritional supplements all day long.

After the pressure of life lessened, Lu Yuan became eager to improve his diet, drinking nutrient solutions all day long, even worse than the lab mice.

After his plan to buy ingredients fell through, Lu Yuan decided to find them himself. Whenever he had free time, he would search around the nearby desert.

In the end, he actually found a few clumps of green grass in a patch of yellow sand; the grass looked a bit like scallions.

Lu Yuan took the grass back and boiled it in hot water. To be honest, without oil or salt, the cooked food didn't taste very good; it was just the pure taste of grass.

But it still brought tears to Lu Yuan's eyes. After so long, he was finally able to eat food other than nutrient solution.

Lu Yuan warmly invited Rhine to eat with him, but Rhine politely declined. At the same time, when Rhine heard Lu Yuan praising the grass, she couldn't help but look at him with affection.

In addition, Lu Yuan has gained a little weight recently, and is no longer the skinny monkey he used to be.

With his well-defined features and bright eyes, Lu Yuan was still quite handsome, even though he couldn't compare to Rhine's anime-model face. Standing in front of the metal plate that reflected his image, he thought to himself with a touch of self-satisfaction.

Moreover, my training with Rheinland recently wasn't in vain. Although I didn't develop bulky muscles, I'm not as weak as before.

According to Rhine, in terms of sheer strength, Lu Yuan is already able to outperform a large number of male insects.

"My lord, stop looking at yourself. We've collected enough for today; it's time for us to head back."

"Okay, I'm coming right now."

Lu Yuan, who was still admiring himself in front of the metal plate, quickly looked away, picked up what he had picked up, and walked towards the Rhine.

After the two insects reunited, they walked towards the edge of the garbage dump. Suddenly, a commotion arose from somewhere.

Then, Lu Yuan felt as if a large shadow had fallen over his head.
