If it was only a one-time exile, as long as the timing was right, there was still a chance to use spatial coordinates and other means to find it.
However, once the chain banishment was carried out multiple times, the spatial coordinates would change to a certain extent. In theory, if the banishment was done enough times, the entire set of spatial coordinates would become unrecognizable.
If he wanted to find his original coordinates in the void, he had to turn back time and time again. There could not be the slightest deviation in the entire process.
If what Madam Qing said was true, and there were 36000 chain banishes from the beginning, then the possibility of going back and forth in the void 36000 times without any error from beginning to end was at least at the lowest limit in mathematical calculations.
In reality, it was impossible for it to exist. Even if the God of space came to review it, he would probably scratch his head.
