Lambda Light Band

In 2070, He Qi is a lieutenant colonel in China's Space Force. The newly established force is mainly responsible for clearing asteroids from Earth's orbit. During a mission, a fragment of an asteroid damages the engine of He Qi's small spacecraft, sending it out of control. With no other option, He Qi can only steer the ship, carrying the nuclear bombs used to clear asteroids, toward a lake on Titan...

A hundred years later, in 2170, scientists wake He Qi. They explain that they need him to report what really happened during that disaster. As it turns out, what struck the spacecraft's engine was not an asteroid fragment, but a streak of light speeding past. There are clear burn marks on the spacecraft's hull.

He Qi begins adjusting to the future, but soon discovers that his former unit has been disbanded. When he asks his superiors, he learns that fifty years earlier, a defecting spacecraft fled into an unknown region while being pursued by several large starships. When the pursuing fleet was about 200,000 kilometers from the defector, several bands of light flashed over the starships, pierced the defector's vessel, then shot straight into the depths of space.

Many wondered whether this was merely some kind of natural phenomenon, but repeated observations proved otherwise. The bands of light began appearing frequently, and each time they appeared, they flew off in the same direction.

The sudden interference of another civilization dealt a heavy blow to Earth's leaders' confidence in space exploration. They reduced the Earth Space Force to its smallest possible size and did their best to disguise Earth as a primitive world: planting vegetation and relocating humanity to underground cities.

During this time, human aerospace and information technology advanced by leaps and bounds. Humanity planned to use these technologies to find a way to survive. He Qi's revival was no coincidence. Earth's government was trying to recall as many first-generation officers as possible, because it intended to rebuild the Earth Space Force.

He Qi had made enormous contributions to the founding of Earth's Space Force a century earlier, so he naturally joined the team. To his delight, he met many people he had known before, including his former superior Wang Zhenmin and his friend Zorn...
