Other than the fire, there was also the problem of materials. There were many good things in Zhao Hai's space, but he couldn't take them out of the space, could he? Wouldn't the secret of his space be exposed? To be honest, he could reveal the secret of the array, but he could not reveal the secret of the space.
However, if they didn't take the materials out of the spatial space, they would have to find the materials themselves. However, it wasn't an easy task for Zhao Hai and the others. The materials for refining were very heavy. Unless they got a material like the Golden Shark sword, they would usually use alloys because it was impossible to achieve the best effect with only one type of metal.
However, they didn't even have the most basic iron material, let alone alloy. Unless Zhao Hai melted all the spare weapons to get some alloy, they didn't have any alloy materials.
