The remaining seven thousand kilograms of the tungsten steel were sent to the castle as Dudian returned. He ordered Nicholas to arrange people to transport the raw materials behind the castle. As for the already melted three thousand kilograms of the tungsten steel, they were stacked next to the training ground.
Dudian commanded Sergei and Jin to carry the furnace from the basement to the training field. It was a small melting pot about three meters high. He had bought it for 10 gold coins from the market. Although ten gold coins wasn't worth mentioning for him but for civilians it was the amount of savings for seven or eight years.
Sergei brough the coals that were bought by Nicholas. In the absense of electricity they were using coals to fire for steel welding.
"Master, why are you making such a big cage?" Jin asked out of curiousity as he saw the length of steel columns.
