Meng Xing's intelligent light-emitting device (actually a stolen pioneer technology device that can detect other pioneers' relics) can accurately explore the existence of human beings. Meng Xing originally thought that the luminous signal displayed on the intelligent luminous device represented the relics and scientific and technological items left by the pioneers, but in fact, every luminous signal is a recycler and a person. In the novel Battle of Fengxing, it is precisely because the jackal missionary ship discovered the so-called "relics". The Star Alliance worships pioneers as gods, but kills humans who may be descendants of pioneers. This may be because if the truth that human beings with quite backward technology are descendants of pioneers spreads in the interstellar alliance, it may lead to the collapse of faith and make the interstellar alliance cease to exist.
So far, engineers are the only known "non-mechanical" life race created by pioneers and joined the Star Alliance.
Pioneers can copy a complete life individual according to the coded data of DNA/RNA/ silicon element samples recorded in the information flow database. All this information is mentioned in bestiarum: the coded data of DNA/RNA/ silicon samples are stored in the information flow database, and any personal copying behavior under the pretext of research and analysis is prohibited in the facility.
The pioneers seem to have a subtle and close relationship with human beings in genetic inheritance, and the information in Rainbow 5 server also confirms the above view in some aspects. The mention of human beings in the data may be the final answer to the mystery left by the pioneers themselves. Prejudice monks also made similar remarks in the novel Halo: Battle of Fengxing. After learning from the Oracle that human beings are descendants of pioneers, the three archbishops finally decided to wage a genocidal war against human beings.
