The reason for this arrangement was because the Adjutant thought that perhaps this alien had his own followers. Although intelligence showed that all actions against them only appeared to involve this alien alone, who could guarantee he didn't have other companions?
The Shi Family on Sek Planet organized a meeting. They arranged for the scapegoat and buried a significant amount of explosives at their feet. Additionally, to ensure safety, they arranged a considerable number of Long Warriors and heavy weapons.
At that time, the Adjutant who planned this scheme thought, even if this alien traveled alone, he would have numerous followers who worshipped him. No matter what, his followers would accompany him eventually. They would not let these civilians go, so he planned meticulously, deploying a large number of troops in Zhou District to prevent any mishaps.
