Under the biologists' dissections, the "cannon" on the back of the vesicle organisms was removed.
Through dissection, the biologists determined this was a channel about two meters in length made of endoskeleton and muscle. It indeed belonged to something that could grow on a biological entity, but no normal biology or naturally existing individual could develop such an organ on its own body.
As for its working principle, it compresses a large lung chamber within the vesicle organism that's connected to the cannon barrel through muscle contraction, similar to a child shooting paper balls through the nostrils, ejecting vesicles filled with high-temperature corrosive liquid to attack the enemy.
Moreover, the vesicles ejected were not as Chen Xin and his team initially expected, forming as spheres within the body of the vesicle organisms.
