The Formation's strength was inadequate; it couldn't withstand the pressure of the closing boundary membrane.
This was the problem with the current failure.
As for whether there were other issues, Jiang Fengwu didn't know; after all, the first experiment failed right at the beginning.
However, it was likely that there would be many more problems to come, all for Jiang Fengwu to solve one by one.
The first problem she encountered was actually easy to resolve; it only required an increase in the Formation's power.
Within three months, Jiang Fengwu had improved the Formation based on its original structure.
After another experiment, the Formation succeeded in withstanding the pressure of the closing boundary membrane, but the second problem emerged.
It was impossible to establish a connection to the Spirit Vein!
