Shen Yurou's actions were quite smooth.
In the abyss, magma flows were rampant everywhere, thus producing a large quantity of demon iron ore.
The four of them had scoured so many palaces that they could say their hands were full of a mountainous pile of ore resources.
Since they needed to create various mechanical creations, Shen Yurou's Spatial Backpack contained a smelting furnace.
So she randomly took out a few ingots specially produced in the abyss, let the stone golems hold them in the magma to see how they resisted corrosion.
Several types of metal ingots were not afraid of the high temperature and corrosion of the magma, so she decisively picked the most abundant type of ingots to start melting in the furnace.
The lavish Zi Liyuan had bought furnaces that used energy crystals to melt metals, those special kinds of furnaces.
Thus, in just a couple of hours, Shen Yurou had melted a large metal plate as thick as a fist.
