Adam pointed out all of Chase's flaws and didn't miss any minor detail, knowing that Chase would put everything he said to use and improve as a whole.
His main points were that Chase needed to continue working hard and developing, but would need to take on board Adam's advice and improvements.
Adam recommended Chase to temper his body using harsh methods that only Chase's body and mind could handle, and also handed over a forbidden body tempering method to him.
It was forbidden because it had caused many deaths and many were unable to even get past the first step due to the extreme pain and strain that it caused the body, but Adam believed that Chase could handle it.
Along with that, Adam told him all the improvements that he could make in terms of how he fought, and advised him not to become too reliant on his Hardening Ability.
It should be something that he used to its fullest, but it shouldn't be his only method of defence or combat.
