Several days ago.
After Lu Ban had sent off the package, he pondered that it might take some time for the people at the institute to make a breakthrough, so he didn't hold out much hope.
The physical annihilation of the Demonic Tide meant that Lu Ban needed a continuous output.
The original Demonic Tide lasted for seven days, but who knows how many days the ancient Demonic Tide would last, and according to Shia, in the ancient Night Country, humans had a much larger range of activity. Defending against Demonic Beasts along such a long defensive line, relying solely on explosions might not guarantee success.
Therefore, items like the "Small-Scale Catastrophe Generator" or an enhanced, amplified plus version, capable of creating a sun, would be far better.
He first went to the Silent Department Store to search, hoping someone had picked up that radio in the Wasteland and listed it in the store.
Unfortunately, Lu Ban did not find the familiar figure.
