Crystal stones are artificial crystals that are placed closest to the planet's energy emission. In this way, the energy emitted from the planet's interior is continuously absorbed by a receiving device fixed to the crystal. Slowly, the crystal becomes an energy-bearing crystal stone, commonly known as an energy crystal stone.

After the crystal stone was invented, Originally, there were one or two planets inhabited by humans. However, because some planets were like those inhabited by the Dark Cold Race, because they were relatively far from the sun, they consumed much more energy than the seven planets inhabited by Yiyang Race and the seven planets inhabited by humans.

As a result, the energy crystals on their planet were not enough for them to use, and it would take at least one to two years for ordinary crystals to become energy crystals. This obviously could not sustain the Dark Cold Race's needs.

More importantly, most of the raw materials for these crystals were from planets inhabited by humans. This made it impossible for them to create more crystals. More importantly, they could not think of any other way to obtain energy. In order for their race to continue to survive, they began to covet the energy crystals of the humans.

Of course, humans would not easily hand over the energy crystal stones they had painstakingly obtained to the Dark Frost Race. As a result, another battle between the Dark Frost Race and humans began, a battle for the energy crystal stones.

The Dark Frost Race had already begun to compete with the human race for energy crystal stones before attempting to occupy the planets of the human race. The battle for the planets and for the energy crystal stones was going on at the same time. Whoever became the winner would be able to survive in this vast universe.

Xiao Yue and Du Ye left for Lufa Star three days later. Two weeks later, the headquarters received news from Du Ye from Lufa Star. Both sides suffered heavy casualties, but the human race still won the battle. Xiao Yue and Du Ye took back the energy crystal stones from the Dark Cold Race.

Afterwards, Wu Yan told them to bring the crystal stones back to the headquarters to prevent the Dark Cold Race from snatching them away again. Actually, when Du Ye was reporting to the commander, he had concealed something. Originally, he didn't want to conceal anything, but when he reported the battle to the commander, Wu Yan, he found Su Nuo in the conference room through the screen. Du Ye felt that it would be better for Xiao Yue to let Su Nuo find out about this when he returned to the headquarters.

Du Ye actually knew that although Su Nuo rejected Xiao Yue's confession, she still liked Xiao Yue in her heart. He had already noticed this point. Perhaps this was the so-called'bystander is clear '.

The thing that Du Ye hid was that Xiao Yue was stabbed in the left eye by the Dark Cold Race during the battle. Although he had received emergency treatment later, the doctor still said that Xiao Yue's chances of recovering his sight in his left eye were very low. Although Xiao Yue was calm on the surface, Du Ye could tell that beneath his calm surface was a broken and disappointed heart.

Su Nuo, who was at the headquarters, seemed to be calmly waiting for Xiao Yue and Du Ye to return. Actually, her heart had been very unstable since Xiao Yue left for Lufa Star. She knew that Lufa Star was a planet with an extremely harsh geographic environment. Although it had been modified by humans, only a small portion of it was suitable for humans to live on. The rest were desert and dry seas.

Perhaps it was precisely because of this reason that they sent Du Ye, who was the more flexible of the seven squad leaders, and Xiao Yue, who was the more skilled in swordsmanship and fighting, to carry out this mission, hoping to solve the problem more quickly.

Su Nuo had always been very worried and afraid that she would see Xiao Yue get injured. She kept telling herself that not dying was the best thing for people like them. It was not surprising that she was injured.

However, her heart was not convinced at all. During the two weeks that Xiao Yue had been on the mission, Su Nuo had been eating and not thinking. She often couldn't sleep all night. She knew that she had sunk too deep into it and couldn't move her heart away from Xiao Yue.

However, he had already rejected Xiao Yue's confession and told him that he had no feelings for him at all. The current Su Nuo did not know how to face Xiao Yue. She felt that she was the stupidest fool in the world.

Originally, he thought that as long as he left Xiao Yue, he would no longer like Xiao Yue. As long as he rejected Xiao Yue, his heart would stop loving Xiao Yue. This way, Xiao Yue and himself would not be hurt.

But now it seemed that she was wrong, and that she was wrong. Su Nuo finally understood that when the two of them had feelings for each other, separation was the greatest harm to both of them, and Su Nuo's idea was quickly verified, and it was verified with her own eyes.

There are many things that happen like the arrangement of God, destined to happen. The idea originated from a helpless explanation of the unpredictable future and the misfortune that occurred around us. In fact, this is also a comfort to the human mind when facing the misfortune. This theory is commonly called the theory of nomenclature.

When people are faced with difficulties and are prepared to solve them through their own efforts, they will use another theory, that is, the strength of a person is boundless, can solve all difficulties, people should challenge their own destiny, should not yield.

But when people, through a period of effort, discover that their strengths cannot solve problems as they think, especially in the face of serious setbacks, they will use the fatalism mentioned above to explain their failures. For the inevitable occurrence of misfortune, people will use fatalism to explain all of this.

Su Nuo had always wanted to break through this fatalism and change her fate through her own efforts. She did not know what the future would be like, but she firmly believed that as long as she did her best, as long as her choice was correct, she would definitely not regret it in the future.

But what if his current choice was wrong? What if your decision was wrong? Su Nuo did not dare to imagine that she was afraid that her decision on Xiao Yue was wrong. A deep fear gradually spread throughout Suno's heart.

Xiao Yue and Du Ye returned to the headquarters in mid-November. The captains waited in the conference room as usual to welcome the winner. When Xiao Yue and Du Ye walked into the meeting room, they naturally became the focus of everyone. Everyone smiled and welcomed them.

However, not everyone was smiling. Du Ye noticed Su Nuo at the first glance when he entered the meeting room. Du Ye saw Su Nuo staring at Xiao Yue in surprise, and then his eyes were filled with pain and sorrow.

Du Ye felt that this gaze was the same as the gaze he saw in the Lufa Star Hospital when Xiao Yue knew from the doctor that his left eye was going blind. It was filled with pain and sorrow.

At this time, everyone went forward to congratulate Xiao Yue and Du Ye. Only Su Nuo was still sitting in her seat, staring at the injured Xiao Yue motionlessly. As for Xiao Yue, who was surrounded by everyone, after sensing Su Nuo's gaze, he turned his gaze to Su Nuo. However, after looking at Su Nuo calmly, he turned his gaze away and looked to the other side, chatting and laughing with everyone.
