Everyone spent several hours in the Virtual World.
Except for Xu Lin, who had a special case, others stayed for a maximum of just over four hours, and the shortest was a bit more than two and a half hours.
There are many technical challenges to overcome next, and extending the duration of the stay is one of them, but there isn't just one technology involved here.
Besides testing the duration, there is also testing the sensory system.
In Xu Lin's view, the sensory system is crucial, much more important than how long one can stay.
After all, if by that time they can complete a sensory system that is indistinguishable from reality, the Virtual World would essentially be a parallel world. For example, if your auditory, olfactory, tactile, and taste senses are the same in the Virtual World as in the real world, then wouldn't that world be real enough?
After a few hours, Xu Lin and the others had tested quite a lot of data.
