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

Upon waking up in the morning, the first thing Lu Yuan did was to check on Rhine's condition.

Rhine was still lying in bed, not awake. He would usually be up by now. It seems that the recovery from a broken bone is indeed quite exhausting.

Lu Yuan checked Rhein's forehead; his temperature was normal, and he was relieved.

Rhine definitely couldn't go to the junkyard together today, so Lu Yuan tidied himself up a bit and went out alone.

He had only taken a few steps when he went back, placed a bag of nutrient solution and a bottle of drinking water on the stool, moved the stool to the bedside, and then went out again.

On the way to the landfill, Lu Yuan saw a strangely shaped rock that looked a bit like a turtle. He chuckled and said it naturally.

"Rhine, look, that rock looks like a turtle."

His words lingered in the air, and Lu Yuan received no response. Only then did he realize that Rhine was resting at home and had not come out with him.

During this period, Lu Yuan and Rhine were basically inseparable, going everywhere together. Now that Rhine was suddenly not by his side, Lu Yuan felt quite unaccustomed to it.

Forcibly ignoring the surging sense of loss, Lu Yuan quietly continued walking towards the garbage dump.

Arriving at his own territory, Lu Yuan quietly picked up trash. During this time, Rhine had taught him a lot, and his efficiency in picking up trash had improved significantly.

His movements were as quick and precise as ever, but he seemed a little down.

"Lu Yuan, how come you're the only one out there? Where's Rhine?"

A nearby female insect asked a question.

"The roof at home is broken, and Rhine is fixing it."

Lu Yuan made up an excuse and didn't tell the truth.

Having stayed for so long, Lu Yuan had a general understanding of what kind of female insects in the garbage dump were. To put it bluntly, they were bullies who preyed on the weak and feared the strong.

If they knew that Rhine was recuperating at home with a broken leg, they would definitely dare to seize the territory now.

Without chatting much with the female insect, Lu Yuan continued to bury himself in his work. Suddenly, he saw a book lying at the bottom of a pile of scrap metal in the distance.

The Zerg Empire had long since gone paperless, with all information stored online. Paper books had long since disappeared. This was the first time Lu Yuan had ever seen a book since he had traveled to the Zerg territory.

Lu Yuan walked over and carefully pulled out the book. The book was quite thick, but the cover was covered in stains, so he couldn't make out the title. He could only vaguely make out the three characters "精", "雄", and "教".

Lu Yuan thought that he was quite bored at night recently, and Rhine had to rest and couldn't chat with him. Having a book to read would be a good way to pass the time, so he found a clean cloth, wiped the book, and then put it in his arms.

At night, under the dim light, Lu Yuan flipped through the books he had brought back.

After flipping through the first few pages, Lu Yuan roughly understood that this was a textbook that taught male insects how to train and improve their mental strength.

But can the spiritual power of male insects be trained? In the memories Lu Yuan obtained, the spiritual power of male insects is determined from the moment of birth; a higher level of spiritual power means stronger spiritual power, and a lower level of spiritual power means weaker spiritual power.

In schools for male insects on other planets, they only teach male insects how to use their mental power to soothe female insects. I've never heard of teaching male insects how to train and improve their mental power, so this book is probably a scam.

Despite his doubts, Lu Yuan had nothing else to do, so he continued reading. As he read, his eyelids began to droop.

Despite being described as a textbook, the content is indeed dry and boring, but its hypnotic effect is superb.

Yawning, Lu Yuan flipped directly to the back pages of the book, hoping to find something interesting. But what he found made him blush with embarrassment.

The following pages were not text, but pictures. At first, Lu Yuan thought it was to make the text easier to understand by presenting the content of the preceding text in the form of pictures.

Upon closer inspection, it was discovered that this was actually a picture of fairies fighting, and the two sides fighting were naturally not men and women, but male and female insects.

The moment he saw it clearly, Lu Yuan felt like his head was about to burst into flames. He reflexively slammed the book shut, stuffed it under the mattress, covered himself with a blanket, and lay down to sleep.

That very night, Lu Yuan had a long-awaited dream of fighting someone until dawn. But as he fought, he discovered that the body structure of his opponent was different this time.

Lu Yuan was startled awake. It wasn't fully light when he woke up. He sat up and gasped for breath. Just as he was about to lie back down and continue sleeping, his face suddenly darkened.

Lu Yuan lifted the blanket, and his little brother was standing tall and saluting the sky.

Lu Yuan muttered under his breath, "Shameless."

......

"Huffing and puffing..."

Early in the morning, not far from Lu Yuan's house, Rhine was jogging easily ahead, while Lu Yuan followed behind, panting heavily.

Three days had passed since Rhine broke his ankle. The elderberry had worked well, and Rhine's bone had healed completely without any complications.

Once his leg was healed, Rhine started exercising every morning, and Lu Yuan, who had long wanted to exercise, joined Rhine in doing so.

Rhine performed those movements with ease, and his breathing didn't change much after he finished. Lu Yuan, on the other hand, would turn into a zombie halfway through each exercise, his face contorted and his breathing labored.

And now, Lu Yuan is about to pass away again.

After running a few steps, Lu Yuan felt as if his legs were filled with lead, his breathing was rapid, and he could taste blood in his throat. He couldn't hold on any longer and collapsed on the road.

When Rhine returned from training, Lu Yuan was still not up.

"My lord, come up."

Rhine squatted down with his back to Lu Yuan, preparing to carry Lu Yuan back.

Lu Yuan didn't make a fuss; he was truly too exhausted to walk any further. With the little strength he had left, he climbed onto Rhine's back.

Rhine's back is very broad, and Lu Yuan felt very comfortable leaning against it.

On the way home, Rhine couldn't help but ask.

"Master, why are you training with me? These are all training programs for female soldiers, too strenuous for male insects, you can't handle them."

"Are there any training programs for male insects?"

"Uh, no."

"Then there's nothing I can do but keep training with you. I want to get my muscles back," Lu Yuan said dejectedly.

Upon hearing this, Rhine smiled.

"Master, don't joke around. Male insects can't build muscle."

Lu Yuan felt as if struck by lightning; did this mean he would be destined to be nothing more than a boiled chicken from now on?

Lu Yuan looked so pitiful after being so devastated that Rhine couldn't help but comfort him.

"Master, muscles and such are not important to male insects. What is most important to male insects is their mental strength."

Speaking of mental strength, Lu Yuan thought of the textbook he had picked up before, and he asked.

"Rhine, can the mental strength of male insects be improved through training?"
