This is quite complicated ... Before the mass production of Star Warrior, the Emperor created some super humans similar to Star Warrior, called Thunder Warrior. Thunder warrior is more powerful than ordinary star warrior, but because of imperfect technology, it is very unstable and has a short life. Originally, the Thunder Warriors also made great efforts in expanding their territory, but after the Star Warriors could be mass-produced, the emperor killed them all because of the instability of the Thunder Warriors. This is one of the foreshadowing of the warriors' betrayal. )
Zhan Shuai has a good relationship with the emperor. How good is it? Once the emperor and the war general were discussing the battle plan ahead, and neither of them was wearing power armor. As a result, the headquarters was raided and the two men fought side by side back to back. Zhan Shuai was shot in the head by plasma without wearing power armor (real head iron … ordinary SM doesn't need to wear power armor, even if he wears power armor to get plasma, his head will be smashed …) The emperor kept guarding Zhan Shuai until reinforcements arrived. On another occasion, the emperor and the war commander went to crusade against the orcs. When the emperor was caught by a huge orc Lord and was about to be crushed to death, Zhan Shuai rushed to cut off the arm of the orc Lord and saved the emperor. It turns out that the two really have a lifelong friendship ... The emperor is very satisfied with Zhan Shuai, and Zhan Shuai also respects the emperor.
It was just around the corner for two people and other protozoa to conquer the whole galaxy. However, Zhan Shuai was later stabbed to death by a cult with a ritual dagger blessed by Gao Na (one of the four evil gods), cursed by the power of evil gods (the symptom is that there is always a voice echoing in Zhan Shuai's mind, torturing Zhan Shuai's spirit), and then invaded into the spiritual world by Erebus (evil things are always made by the latter product ...), with the power of evil gods, Zhan Shuai thought that the emperor would kill all the stars like killing all the thunder fighters after unifying the galaxy. At the same time, he declared to Zhan Shuai that the four evil spirits in subspace are the truth of the universe, and the emperor was just a clown who stole the power of truth (the most terrible thing was that the technology of 20 genomes really came from subspace ... and the emperor didn't tell Zhan Shuai about it), so Zhan Shuai believed the temptation of Erebus and called on other warring factions eroded by evil spirits to overthrow the "cruel" rule of the emperor.
