The gate
/*unedited*/
While everyone was in a panic and in a state of helplessness, Shin Jiao has slowly but meticulously pieced out every piece of information he got from the glasses. Then with the speed of the glasses in computing the result, it didn't take long enough for it to show Shin Jiao the probability and the solution to his problem.
There are two options.
The first one is to create a hole in the cloud defense array as it is actually a moving formation. If Shin Jiao could time it out and hit it exactly with an array breaking formation slab, then he can break the defensive barrier. But the problem is he didn't have time to watch the movement of the dark cloud.
The second option is the fastest but the most dangerous. This is because there is a chance that Shin Jiao might let someone or something inside the gate as it would open it within the window of time of around 5 minutes before it would close.
