"Finally found it, this professional factory." Zhao Guang paused in front of a special factory.
Just as Zhao Guang was looking for materials for cultivation, the first thing that came to mind was titanium alloy armor. Titanium alloy is also one of the hardest materials on Earth, in terms of metals, of course.
Because when cultivating the Solid Wall Armor, one must use metal armor and not any other material.
If any other material were used, it would be impossible to dissolve and absorb it through this battle skill.
Zhao Guang himself did not understand the specific reason, but this was a conclusion drawn from countless years by the Chirali Empire, possessing very high credibility. In this regard, Zhao Guang believed he could not change it in the short term.
However, factories capable of producing titanium items were very difficult to find.
