Earth, a hundred years later, the surface environment is not so bad, but the life of the refugees is still not rich, and they are still vassals of the dungeon.

Humanity is still divided, but this time it is different from the previous one, this time the Space Fleet has become a regime on its own.

The first soldiers of the Space Army who hibernated were awakened, and these soldiers were successively marked with the 'Mental Seal' of victory at the Bill Institute.

Four wall-breakers, four plans. Mercury's plan to hit the sun, the lightning ball to create a ghost fleet, and the thought steel seal plan, and Luo Ji's no plan, the first two plans ended in failure.

The Thought Seal looked quite successful, because a group of soldiers were stamped with the Iron Seal, believing that the Earth would win. And now that the number of human fleets has surpassed the number of immigration ships of the Trisolaran, the victory of human beings has become the mainstream, so the soldiers of the Thought Steel Seal have been awakened to prepare to go to the universe, fulfill their oath a hundred years ago, and defeat the Trisolarans The earth belongs to the earth.

But just as Bill and his wife, the developers of the Mind Seal, wake up to a low-hanging victory, the unexpected happens.

His wife, Keiko Yamasugi, turned out to be a wall-breaker for her husband Bill.

After a hundred years, the wall facing plan is no longer important, but the spies of the Trisolarans have not forgotten the mission.

This is definitely a big blow, and the wife turned out to be the enemy, which is simply the greatest malice in the whole universe.

"Bill Hines, I'm your wall-breaker. Keiko Yamasugi already knows Bill's true face: "There is indeed no problem with your ideological seal, but the idea you put into the soldiers is completely opposite, it is not that humanity will win at all, but that humanity will lose." You think that humanity should flee the solar system to avoid contact with the Lord, and you are a complete defeatist. ”

This truth has caused an uproar in the world again, doesn't that mean that the soldiers are defeatists?

In this age of triumphalism, defeatism is not allowed. The Earth side immediately set about arresting all the soldiers who had been imbued with the Thought Seal.

However, just when Keiko Yamasugi, the wall-breaker, was about to be arrested, Bill suddenly said in surprise: "Keiko, in fact, I already knew that you were a spy of the Trisolaran, and Denisha had already told me." ”

Keiko Yamasugi doesn't think she's exposed, she's a greater deceiter than the one who faces the wall: "Impossible!" so she categorically won't accept this argument.

"Do you remember her Inception system? Actually, she stole all of my secrets and yours when we first met, including my defeatism and your spy. Bill remembered the image of Denisha confronting himself for defeatism for the first time, and his surprise was not to mention.

"How is that possible?" Keiko Yamasugi didn't believe it would be like this: "Then your mind seal has changed?" She found out that Denisha was the master of disguise, and this being, who had once become the greatest woman on earth, was so scheming that it was impossible to prevent it.

"No, she didn't blame me, she just told me to keep doing it. What really matters to her is you, you have provided a lot of information to the Trisolarans, and a lot of the information is fake, and a lot of this false information is implanted in your dreams through the Dream Inception System to make you believe it. ”

At this time, the wall-breaker has been completely trapped, could it be that the person who has been used for so long is himself?

"What the hell did Denisha do?" Keiko Yamasugi asked nervously, although she believed in the Trisolar, she was also worried that the wrong information she gave would affect the Trisolar.

"She used you and me as a cover to deceive the Three-Body Person, in fact, in secret, she has completed a new ideological steel seal - the Three-Body Seal. "The seal of the three-body problem is hidden in the information you transmit to the three-body world, and it spreads through the spectrum, which can make the three-body people more positive. Bill said.

"Positive?" seems like a good thing.

Bill himself didn't know what Dinisha was thinking, he guessed like this: "Maybe Dinisha hopes to save mankind by improving the ideological quality and moral level of the Trisolarans." As long as the Trisolarans themselves give up the invasion, then the earth will be fine. ”

"Jokes, in the face of survival, ideology and morality are nothing. "Keiko Yamasugi admires the survival spirit of the three-body people, two hundred civilization changes have not extinguished the three-body people's desire to survive, not only did not eliminate them, but made them more and more developed and more advanced, this alone is far less than the earthlings. So she hopes that the Trisolarans will come, and as for Denisha and Bill's efforts, they are just useless: "Denisa's methods are not necessarily superb." ”

However, Dinisha's plan is actually in cooperation with Duran, Dinisha makes the Trisolarans more motivated, and Duran makes some Trisolarans lag behind, with the ultimate goal of dividing the Trisolarans.

A united three-body society is impossible for human beings to overcome, but after differentiation, there is a chance.

Dinisha makes the Trisolarian more positive, more racialized, more extreme, and more intolerant of wrongdoing compatriots. And Duran is creating mistakes in the three-body society.

But she did it, proving that the Trisolaran is not invincible. The Trisolarans may be physically stronger than us, but we humans are superior in spirit. "I always thought that the Trisolaran was invincible, but Dinisha gave me hope, in fact, we have always been wrong, the most powerful ideological seal is not a machine, but a hero and a role model. Bill said excitedly: "Heroes and role models can bring hope and victory, which is impossible to bring with the Mental Seal, Dinisha is the strongest Mental Seal on Earth, when the human civil war is intriguing, she brings peace, when the Trisolarans spread the power of invincibility, she brings victory." Seeing her, even I can't help but have hope, believing that there is a slim hope for mankind. ”

Bill believes that Denisha is the one who can reverse defeatism, and that is the real steel seal of thought.

"It's a pity that hope has been extinguished, and Denisha has been missing for several years, but I'm afraid she's dead. Keiko Yamasugi said coldly.

Bill, however, knew that Denisha would never just give up on Earth: "She'll be there when the earthlings need her, and I'm sure that." ”

Keiko Yamasugi discovers that her husband has really changed and is no longer a defeatist.

The other earthlings didn't expect the Queen of Order to secretly play a big game of chess, and she did a better job than the wall-facing people, but could her method succeed? Will the Trisolarans let the earthlings go?

Whether it succeeds or not, the people of the earth are nostalgic for the era when there was Dinisha, and Dinisha's smile is a lighthouse in the storm, a light in the darkness, an inextinguishable warmth, and a mark of the earth.

The earth found out that Denisha really made them really feel the excellence of being a human being, and Dinisha gathered all the advantages of human beings, so that human beings have the motivation to survive. At this moment, everyone finally realized that the earth cannot lack Dinessa, and human beings cannot lack Dinessa.
