Saleen felt a little disappointed, but he did not show it on his face. He immediately thought of a problem. "The Pan's turtle alchemical boat is powerful, but I only have one and I am not hopeful of capturing another creature like the pan turtle. The pan's turtle alchemical boat is Metatrin City's secret weapon, the enemy mustn't know about it. If I have a warship that can dive the existence of the pan's turtle alchemical boat will be concealed. Holy Rock City uses this item to equip its navy which means that it can be repeatedly produced unlike my pan's turtle alchemical boat. If I create a manufacturing method, I will possess a huge number of it, which will be very practical. I don't have to use metals to craft it because I possess thundercloud wood. The thundercloud wood is much tougher than metals and isn't heavy. A lot of magic nuclei can be conserved if it is used in underwater navigation."
