"Glass Bead Seed Barrier" 

The next second, under everyone's bewildered gaze, the girl grew the seed at a fast speed but the seed just expanded in size, enveloping everyone in something that looked like a transparent glass bead! 

This one really looked like a bubble or something because the surface still reflected light, not as transparent as the invisible barrier. 

However, the strange thing was, when the seed enveloped the five people, the temperature inside slowly became warmer, and the flow of water inside the bead was also different from that outside. 

Suddenly, everyone felt as if they were back in their mother's tomb. Warm, comfortable and was just too good.

The glass bead actually didn't look like any mature plant, but if one looked closer, they would see the bead resembling a fruit and some colorful veins appeared on the surface of this bead.
