Sam was sure that he wouldn't be able to complete this machine in ten days. So, he decided that he would do what he can and leave the rest to later and return to the camp.
Anyway, with the aid of beasts at least the process of excavation would not stop.
After working for ten days and making more than half of the required parts, Sam came out of the tower and was greeted by the sunset.
His teammates namely Philip, Kelly and Jack returned to the mansion.
Watt is the first one to greet him. They knew he was here as they saw the fire type beasts working vigorously in the estate to melt the impact crystal.
But they don't know how they collected the molten crystal and cleared it up.
This credit was given to the shadow mice.
They used the space jade rings and delivered everything into the Divine dimension, to be precise to the second floor, where Sam prepared some moulds to let the impact crystal solidify.
