The Dark Forest (Chinese: 黑暗森林, pinyin: Hēi'àn sēnlín) is a 2008 science fiction novel by the Chinese writer Liu Cixin. It is the sequel to the Hugo Award-winning novel The Three-Body Problem (Chinese: 三体, pinyin: sān tǐ) in the trilogy titled "Remembrance of Earth's Past" (Chinese: 地球往事, pinyin: Dìqiú wǎngshì), but Chinese readers generally refer to the series by the title of the first novel.[1] The English version, translated by Joel Martinsen, was published in 2015.

Plot[edit]

The UN forms the Planetary Defense Council (PDC) to coordinate defensive efforts against the impending assault of the Trisolarans, that have launched a massive invasion fleet that will reach the Earth in around 400 years. However, subatomic semi-artificial intelligences sent from Trisolaris (the book's name for the three-star system of Alpha Centauri), known as sophons, have reached the Earth, and conduct surveillance of national secrets and private conversations, and disrupt the operation of particle accelerators, the latter serving to obstruct any new discoveries in fundamental physics. Since the sophons cannot read minds, the PDC decides, in addition to regular military expansion, there will be four people appointed as Wallfacers. They are granted access to the resources of the UN and shall develop and direct strategic plans only known to themselves in order to keep them secret from the enemy. As a result, this also requires them to misdirect and deceive the human world; they therefore don't need to give any explanation for their actions and commands, no matter how incomprehensible they may be. Three Wallfacers are chosen on the basis of merit: Frederick Tyler, a former United States Secretary of Defense; Manuel Rey Diaz, former president of Venezuela, also a nuclear engineer; and Bill Hines, former president of the EU, also a neuroscientist. To general surprise, the fourth Wallfacer is announced to be Luo Ji, an obscure Chinese professor of sociology who is lazy and un-ambitious. The story reveals Luo was chosen because Trisolaris, for unknown reasons, sees him as a threat, and ordered the Earth-Trisolaris Organization (ETO) to assassinate him. In retaliation, Trisolaris appoints three ETO members to be Wallbreakers. They are to spy on Tyler, Diaz, and Hines respectively, to discover and ruin their Strategies. Meanwhile, a PLAN officer, Zhang Beihai, is inducted into China's new Space Force; he displays an unwavering hope of victory, and blames the other officers for their defeatism. Zhang secretly murders some scientists advocating chemical propulsion, so research into non-media radiation drives and controlled fusion engines receives priority. His proposal to enter hibernation for the purpose of fighting defeatism among future generations is approved.

Tyler designs a swarm of small, nuclear-equipped kamikaze space-fighters, but his secret plan to work with the ETO to double-cross Earth's forces, and subsequently to triple-cross the Trisolarans, is published by his Wallbreaker. (The Chinese original of the book has a different plan for Tyler involving ball lightning weapons.[2][3][circular reference]) The government agents denounce him as a war criminal, driving him to suicide.

Diaz requests funding for massive nuclear warheads, and detonates one on Mercury, but his secret plan is exposed by his Wallbreaker: to build a nuclear mechanism able to propel Mercury into the sun, which would lead to Coronal mass ejection consuming the rest of the solar system, and then threatning Trisolaris. At the next PDC hearing, the USA decides to violate Diaz's diplomatic immunity and arrest him, but Diaz escapes by pretending to hold a dead man's switch which can destroy New York City. Returning to Venezuela, he is reviled by the populace as a war criminal, and stoned to death by an angry mob.

Hines conducts experiments to amplify intelligence, in the process, discovering a means of implanting beliefs. The UN allows soldiers to use Hines's device to implant faith in victory against Trisolaris as a controversial means of curbing defeatism. Hines decides to enter hibernation; while he is asleep, the program is terminated as a crime against humanity.

Luo refuses to work, instead using his power as as Wallfacer to live in luxury. He asks Shi Qiang (the detective with Wang Miao in the previous novel, now working as a security officer on the Wallfacer project) to find a woman whose description matches an ideal woman in his dreams, leading Shi to find Zhuang Yan. Zhuang comes to live with Luo, eventually marrying him and giving birth to a daughter, Xia Xia. After five years of living together, Zhuang acts on a plan put in place before she was found by Shi. She and Xia Xia go into hibernation until the predicted time of arrival of the Trisolaran fleet, to force Luo to develop a method of stopping the fleet if he wishes to live peacefully with her again. Desperate to find a way to protect Zhuang and Xia Xia, Luo reflects on a conversation of many years ago with his former teacher, Ye Wenjie, the founder of the ETO, and realizes certain truths about galactic civilizations. Accordingly, Luo arranges for the location of a star 49.5 light-years away to be broadcast throughout the galaxy, using the sun as an amplifier. He enters hibernation, asking to be awoken after an effect on the star is noticed. Four years later, an observatory notices through the tracking of space dust the Trisolaran fleet had launched swift probes on that exact day, forecast to reach Earth in merely 200 years.

Luo, Hines, and Hines's wife Keiko Yamasuki wake up 200 years later to a wealthier and advanced society, albeit without any advancements in particle physics and supercomputing due to the ongoing sophon sabotage. The Earth now has thousands of spaceships larger and faster than Trisolaris' one thousand ships. The ETO was eliminated. The UN is confident of victory, and writes off the old Wallfacer project as an absurdity. Yamasuki reveals she was the last Wallbreaker, and exposes the secret part of Hines's plan: the belief implanting device was inverted, causing its subjects to believe victory was impossible and to conspire to escape the Earth. The human space fleet, worried that the device has produced a secret society of escape advocates, brings Zhang out of hibernation to investigate. Zhang seizes the moment to sedate the largest ship's crew, and drive the ship out of the solar system as a secret defeatist all along. The space fleet sends four ships after Zhang. Meanwhile, the first Trisolaran probe passes Jupiter, and in a show of strength, humanity launches 2,000 warships to intercept it. However, the probe unexpectedly re-activates and rams into humanity's assembled warships, piercing their fuel cells with ease because it is constructed of an ultra-strong material held together directly by the strong interaction. Only two warships manage to escape into deep space, and their crews decide to flee the system rather than return.

Hearing of the defeat, society on Earth suffers mass hysteria. The four warship crews pursuing Zhang decide to join him. However, each crew eventually concludes that they can maximize their chances of survival by killing the other crews and stripping their ships of resources, with only one ship emerging victorious. On the other side of the solar system, one of the two escaping ships also kills the other's crew. Luo explains these events confirm his earlier theory: there is life everywhere in the galaxy, but owing to exponential growth and limited resources, the incentive is very high for each galactic civilization to preemptively kill any others. The only thing stopping this is the lack of knowledge of others' locations, explaining the Fermi paradox. Luo is made a Wallfacer again after the UN notices the star marked by Luo was destroyed. His strategy was to force Trisolaris into a truce by threatening to broadcast their location. However, the Trisolarans prevent this by using their probe to blanket Earth with electromagnetic interference at the earth's Lagrange point. Luo seemingly gives up and joins the government agents in their Snow Project, a futile effort to use nuclear bombs to create vast clouds of debris to track the remaining journey of Trisolaris's fleet. He is shunned by the public for not having a plan to defeat Trisolaris, and descends into alcoholism. However, he encoded a message into the bombs: upon their explosion, the resulting precisely-placed dust clouds will cause the sun to appear to flicker to an extra-solar observer, thereby relaying Trisolaris's location to the galaxy in a type of Morse code. Trisolaris is forced to agree to a truce with Earth and give humanity the ability to produce gravitational wave transmitters.

In the epilogue, the government agents approve of Luo's work and agree to bring his wife and daughter out of hibernation, whereupon they are reunited. Luo converses briefly with the pacifist Trisolaran who had made first contact with Ye Wenjie and who suggests that seeds of love might be present in other areas of the universe.

Wallfacers (面壁者):

  • Frederick Tyler (弗雷德里克·泰勒) – Former US Secretary of Defense. Primary plan was to make a massive swarm of kamikaze fighter craft to combat the Trisolaran fleet. Secondary plan was to remotely control the fighter craft swarm to betray earth and transport a massive quantity of water to the incoming fleet. Tertiary plan was to take remote control of the swarm fleet to detonate hydrogen bombs directly on the enemy fleet ships once within range. Informed by his Wallbreaker that his plan wouldn't have even scratched the fleet. Unable to resign from Wallfacer status, he commits suicide.
  • Manuel Rey Diaz (曼努尔·雷迪亚兹) – Former President of Venezuela. Primary plan was to develop more powerful hydrogen bombs to be used to combat the Trisolaran fleet. Secondary plan was to utilize these hydrogen bombs to slow down Mercury, resulting in a chain reaction where all planets in the Solar System are consumed by an expanding Sol. Blackmails the UN with fake nuclear bombs to revoke his Wallfacer status and return to Venezuela where he is promptly stoned to death by his own people for threatening the destruction of the Solar System.
  • Bill Hines (比尔·希恩斯) – English neuroscientist and former president of the EU. Primary plan was to boost human intelligence to a high enough level to overcome the scientific block on particle physics by the sophons. Secondary plan was to instill an incorruptible state of defeatism in humanity's military, forcing humanity to develop plans to escape the solar system rather than stay and fight.
  • Luo Ji (罗辑) – Astronomer and sociologist. Given the initial axioms of Dark Forest theory by Ye Wenjie. Is his own Wallbreaker when he concludes that the axioms result in the Dark Forest state of the universe, and thus the only strategic option against the Trisolarans is mutually assured destruction through broadcast of their interstellar coordinates.
