Discovery

The Sword Crafting Hall was maintained at a relatively high temperature. Heat waves rolled about in the air, and they were accompanied by deafening sound waves that were everywhere in Sword Crafting Hall. The depletion of a person's mind and soul was incredibly great!

Happy noticed that the young men who bullied him previously had to go outside and sit down to restore their qi after only going about a few rounds. At that time, they were already drenched in sweat. 

Even some of the powerful looking Sword Crafting Hall disciples found it difficult to continue staying in the hall after some time. Once they did a few rounds, they left and had new Sword Crafting Hall disciples enter. 

Happy became more and more impressed. 

It was no wonder why the mighty northern clan could remain at the top of the business world when they had to stay in such a hot and horrible environment. No normal faction of power would be able to do it.
