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

"By the way, Feynman, have you done any research on silver crystals?"

Rhein asked about the main purpose of his visit to the laboratory.

"Silver Crystal? What's so interesting about studying that stuff? When the rumors were at their peak, all the institutions in the empire thoroughly investigated Silver Crystal, but they didn't find anything."

"But I discovered that the silver crystal I'm wearing on my wrist can release spiritual energy."

Feynman looked at Rhine in surprise.

"That's impossible. You're not kidding, are you? Researchers have speculated that silver crystals can release mental energy, but they've studied countless silver crystals and haven't found any such phenomenon."

Rhine didn't argue, but Feynman understood from Rhine's serious expression that Rhine wasn't joking and that what he said before was true.

Feynman then roared and charged at the ring on Rhine's hand, but Rhine stopped him with one hand.

What are you doing?

"Quickly give me that ring you're wearing on your hand, let me study it. It can release mental energy, which is an incredibly great discovery. The Empire has never found anything that can release mental energy before."

"No, this ring is my precious possession."

"ha!"

Feynman was almost frantic, completely baffled as to why Rhine was being so uncooperative.

"No, Rhine, what do you want? You came all this way to talk to me about the silver crystal, just so I could figure out why it can release spiritual energy. But now you won't give me the silver crystal with the problem. How am I supposed to study it?"

Rhein was unable to answer Feynman's question.

He came to the lab to find Feynman because he wanted Feynman to figure out what was going on with the silver crystal. But when Feynman actually asked him for the ring, his first instinct was to refuse. He didn't want to give the gift Lu Yuan had given him to another insect.

"Why don't you study the other silver crystals first? I don't think the silver crystal I have is any different from the others," Rhine said.

Feynman frantically grabbed at his hair, unable to understand why his friend had suddenly become unreasonable.

"Rhine, the one releasing spiritual energy right now is this silver crystal in your hand. This phenomenon has never been observed with other silver crystals. Perhaps there is something special about the one in your hand. Of course, I want to study the one in your hand first."

Rhein knew Feynman was right, but he just didn't want his precious ring to leave his finger.

Feynman tried to persuade her again and again, and finally, under Feynman's almost insect-killing gaze, Rhine reluctantly agreed to give the ring to Feynman for research.

"You must promise me that if you find that this silver crystal on my ring is no different from the other silver crystals, you must immediately return the ring to me and go find other silver crystals to study," Rhine said.

"Okay, okay."

Seeing that Feynman agreed, Rhein struggled to take off the ring and handed it to Feynman.

Just as Feynman was about to take the ring, Rhine snatched it back in a flash, leaving Feynman's eyes wide open.

"No, didn't we already agree on this? Why are you taking it back?"

"When you use my ring for experiments, I need to keep an eye on you the whole time. Also, when I leave the lab, I'll take the ring with me, and you're not allowed to stop me."

"Okay, okay, okay."

Rhine handed the ring to Feynman again, but just as Feynman was about to take it, Rhine took it back. Feynman didn't know what to say.

"When you conduct the experiment, you are not allowed to use chemicals or cutting methods. You must ensure that my ring is returned to my hand intact," Rhine said.

"Yes, yes, I promise."

So Rhine handed the ring to Feynman again, but just as Feynman was about to take it, Rhine took it back.

"What is it now, my ancestor? Can you please tell me your request all at once?"

Feynman felt like he aged several years on the spot from anger.

After taking the ring back, Rhine thought about it carefully and realized that she really had nothing to ask for, so she reluctantly gave the ring to Feynman.

Feynman was overjoyed and immediately took the ring to the lab table, not even bothering to look at Rhine again.

Seeing Feynman's focused back, Rhine gave him a reminder.

"Feynman, I feel that this silver crystal must have absorbed mental energy first before it could release mental energy."

Feynman nodded, indicating that he understood.

That was all the hints Rhine could offer. As for the fact that the silver crystal was releasing Lu Yuan's mental energy, he wouldn't say a word about it.

Rhine had thought about this before coming to the lab: if the silver crystal could absorb and release anyone's mental energy, then with his hints, Feynman would be able to experiment with it sooner or later.

However, if only Lu Yuan's spiritual power can be absorbed and released, then he absolutely cannot let this matter be discovered. He will definitely not let the other insects notice Lu Yuan's abnormality.

......

A few days later, in the legion commander's office.

Rhein was sitting in a chair reading the postwar summary report that Fred had given him, the double-stone ring on his hand gleaming brilliantly under the light.

Fred sat opposite Rhine, his mood rather low. The battle with the Araqi insectoids had resulted in heavy casualties.

The Araqi insectoids mobilized 200,000 insectoids, and their 10th Army also mobilized almost all of its forces, deploying 150,000 soldiers to fight against the Araqi insectoids.

Although they ultimately annihilated 200,000 Araqi Zerg, their own casualties reached as high as 50,000.

The list of the dead attached to the report was so long it seemed to stretch on forever.

Rhein was not particularly affected. In his view, war was a cruel thing, and it was only natural for people to die in battle.

As the corps commander, he ensured the correctness of the decisions and led the 10th Army to victory in the war, thus fulfilling his duties.

As for the rest, he couldn't care less; he couldn't be responsible for the life of every soldier.

Whether a soldier can survive on the battlefield depends on his own abilities.

Those who manage to survive will receive their due reward; those who cannot survive will simply die.

Rhein carefully examined the list of the dead and was pleased to see that the names of his informants were all on it.

He then flipped through the report, in which Fred wrote that high-level females had also suffered heavy casualties in the war and hoped that the capital planet could send another batch of high-level females as soon as possible.

They also hope that the capital planet will allow the Tenth Army to recruit another batch of soldiers from nearby planets to replenish its manpower.

Rhine's fingers traced over the two paragraphs, and he felt he had come up with a good way to further consolidate his control over the Tenth Army.
