Jia Yan was entirely sincere about this. The first of these monsters chosen to go 'there' and undertake the first phase of the work was of utmost importance. Although there may not be a significant threat present in the solar system, the fatigue from the journey and the change in mindset could put immense pressure on the first batch of individuals. Thus, he took the time to encourage them.
There was an additional hazard he hadn't told anyone about!
That was the earlier Auster representative who existed on Earth, perhaps the most scientifically advanced 'Auro' among all the aliens known to Jia Yan!
By now, he didn't believe that such a terrifying figure had died in Daphne's assault, or even that he had lost his life due to an argument with Daphne, when he attempted to report the presence of 'star-condensed substance' on Earth to the exploration ship of the Auster Empire!
In retrospect, it all seemed like groundless rumors!
