Concept Definition
Stellar-class hydrogen bombs are super nuclear weapons developed under the leadership of Wallfacer Manuel Rey Diaz during the Wallfacer Project. Rey Diaz, the former president of Venezuela, was known for his hardline political style and his fixation on nuclear weapons. As one of the four Wallfacers, he was granted virtually unlimited resource allocation authority by the United Nations and devoted all his efforts to developing super nuclear weapons.
The "stellar-class" in the name is not rhetorical exaggeration — Rey Diaz's goal was to create nuclear weapons powerful enough to affect stellar-scale celestial bodies. Traditional hydrogen bombs are measured in megatons of TNT equivalent, with the largest (the Soviet Tsar Bomba) at only fifty megatons. Rey Diaz's stellar-class hydrogen bombs far exceeded this scale, reaching levels that could produce significant effects at planetary or even stellar scales.
Development Process
Rey Diaz's Obsession
Even before being selected as a Wallfacer, Rey Diaz had an almost obsessive focus on nuclear weapons. As a leader from a developing South American nation, he understood that conventional military forces could not compete with major powers — nuclear weapons were the only path for small nations to achieve strategic deterrence capability. This belief in nuclear weapons extended directly into his Wallfacer plan.
Upon becoming a Wallfacer, Rey Diaz immediately launched the stellar-class hydrogen bomb development project. He mobilized the world's top nuclear physicists and engineers, investing astronomical resources. Ostensibly, his research was to "enhance Earth's defense system's nuclear strike capability" against the Trisolaran fleet. While the UN Wallfacer Commission was puzzled by his project's scale, the Wallfacer's privileges prevented them from questioning his true intent.
Technical Breakthroughs
Rey Diaz's team achieved a series of major breakthroughs in nuclear weapons technology. Traditional hydrogen bomb yields are limited by the amount of fusion material and detonation methods; achieving stellar-class power required entirely new physical mechanisms. His scientists explored multiple methods for enhancing nuclear fusion reaction efficiency, including special chain reaction designs that allowed nuclear fusion to become self-sustaining and amplifying, rather than releasing instantaneously and quickly extinguishing like traditional hydrogen bombs.
They also conducted multiple experimental verifications. In space near Mercury's orbit, stellar-class hydrogen bombs were secretly test-detonated. The energy produced far exceeded any conventional nuclear weapon — the flash was clearly visible from tens of millions of kilometers away, and the shockwave and radiation were sufficient to affect planetary-scale bodies.
The True Plan: Destroying the Solar System
The Logic of Mutual Assured Destruction
Rey Diaz's surface plan was to use stellar-class hydrogen bombs to strike the Trisolaran fleet. But his Wallbreaker revealed his true strategic intent: Rey Diaz planned to use the bombs to destroy the Solar System itself.
Rey Diaz's actual plan was this: deploy tens of thousands of stellar-class hydrogen bombs on Mercury's surface and in its orbit, forming a massive chain reaction system. When all bombs detonated simultaneously, the energy generated would alter Mercury's orbit, pushing it toward the Sun. After Mercury plunged into the Sun, it would introduce massive amounts of matter and release enormous gravitational potential energy, triggering runaway nuclear reactions within the Sun — the Sun would undergo a nova-like catastrophe, releasing enough energy to engulf the entire inner Solar System.
This was a mutual destruction plan: if the Trisolaran civilization did not abandon its invasion of Earth, Rey Diaz would destroy the Solar System, leaving the Trisolaran fleet to arrive at nothing but superheated ruins and a dying star. Earth and human civilization would be annihilated in this catastrophe, but the Trisolaran civilization's invasion target would also become meaningless.
Strategic Logic
Rey Diaz's plan had a cold but internally consistent logic. He believed that facing an alien civilization with technology far superior to humanity's, there was no possibility of military victory. All conventional defense plans — whether space fleets, planetary defense systems, or underground shelters — would be useless against Trisolaran technology.
The only bargaining chip for "equal dialogue" with the Trisolaran civilization was the capability for mutual destruction. If humanity possessed the ability to destroy the Solar System and demonstrated the resolve to use it, then the Trisolaran civilization would be forced to reassess the cost of invading Earth — conquering an already-destroyed star system would be pointless.
This logic shares striking similarities with the Dark Forest deterrence Luo Ji later established. In fact, Rey Diaz's plan can be viewed as a primitive version of Dark Forest deterrence — using the cost of self-destruction to deter the enemy. The difference is that Rey Diaz's deterrence targeted the Trisolaran civilization itself, while Luo Ji's deterrence targeted all hidden hunters across the universe.
Wallbreaking and Failure
The Wallbreaker's Exposure
Rey Diaz's Wallbreaker saw through his true intentions. The Wallbreaker pointed out that while Rey Diaz appeared to be developing weapons against the Trisolaran fleet, he was actually preparing an apocalyptic strike against the Solar System itself. The deployment location of the stellar-class hydrogen bombs (Mercury's orbit), their quantity (far exceeding what was needed to strike a fleet), and their detonation method (chain reaction to push Mercury) all pointed to an inescapable conclusion: Rey Diaz intended to destroy the Sun.
The Wallbreaker's revelation caused worldwide panic and outrage. A Wallfacer — a guardian entrusted by humanity to defend Earth — had been secretly preparing to destroy Earth itself? This sense of betrayal was even harder to accept than the threat of alien invasion.
Rey Diaz's End
After his Wallfacer plan was broken, Rey Diaz was stripped of his Wallfacer status. Upon returning to Venezuela, he was attacked by furious crowds. The people who had once supported him now viewed him as a traitor to humanity — a madman who had tried to destroy humanity's home with nuclear weapons. Rey Diaz was ultimately stoned to death by the angry mob, meeting an extremely tragic end.
Rey Diaz's tragedy lies in the fact that his logic was, in a certain sense, correct — facing an absolute technological gap, mutual assured destruction may indeed be the only means of deterrence. But he overlooked humanity's most basic emotion: people would rather walk toward an uncertain future with hope than accept a certain apocalypse. A guardian who prepares to destroy humanity in the name of protecting humanity is morally unacceptable.
Comparison with Other Wallfacers
The four Wallfacers' strategies reflect different approaches to facing existential threats. Tyler chose the risky gamble of quantizing the military, Hines chose psychological manipulation to alter human thinking, and Luo Ji ultimately found the ultimate answer in Dark Forest deterrence. Rey Diaz chose the simplest, most brutal, and most desperate approach — nuclear annihilation.
Rey Diaz's plan was the most controversial among the four Wallfacers, but it revealed a profound truth: all Wallfacer plans implicitly involved some form of "disposal" of human fate. Tyler disposed of the military, Hines disposed of human thought, Rey Diaz disposed of the star system, and Luo Ji disposed of human civilization's very existence — suspending it above the threat of broadcasting coordinates. The Wallfacer's power is essentially dictatorial authority over humanity's fate, and the exercise of such power inevitably brings moral dilemmas.
