Damian had been thinking about the idea while he was absorbing energy to replenish his energy storages and it was also a good way to clear his mind and sort out everything that he had learnt so far systematically.
To recover his external energy he needed food, resources that could be eaten such as pills and medication and sleep, but his internal energy could be restored by absorbing energy from the atmosphere into his body.
However, that was merely what he had been taught and Damian didn't like to be restricted. He wanted to try out everything, explore and be the greatest. It was the dream of most, but Damian actually had the potential and talent to do so.
[What if I can absorb energy like I do to cultivate internally and stream it into my muscles and try and use it to recover externally] thought Damian to himself.
While breathing, one was unconsciously breathing in energy with the oxygen that their body needed and was why even ordinary people had quite amazing physiques. It was also how small animals, could transform into large beasts.
The energy they were breathing in was also how people were able to recover their external energy, also known as stamina, so quickly. So, what if he could directly absorb energy to recover externally, which would be much quicker and efficient.
If others were to know what Damian was thinking they would call him crazy, but to Damian it made sense, but he knew that it really was as easy as he thought, then people would have been doing it for centuries before him.
Trying to do so, no matter how much he tried to steam his internal energy to recover his external energy, he would always end up reinforcing his body instead of recovering.
He had been trying to do so for so long and in the process, strained himself mentally so much, yet still hadn't been able to even recover his External Energy at all.
[It must be because my External Cultivation is too low compared to my Internal Cultivation and I also need to find out how to completely harmonise them. Even if it isn't the key breaking past the Mortal Cultivation Level, it will increase my power and skill] thought Damian to himself as he collapsed onto his bed and slept deeply.
His mind had been fatigued massively and his body still hadn't recovered, so the best thing for him to do was sleep and while he was sleeping, Utsusu was helping his body to automatically absorb energy in his sleep to assist his recovery.
Utsusu had ignored his questions and declined to talk to Damian about his idea because he wanted Damian to find out most things himself and come to his own conclusions so that he is more independent and capable.
Upon waking up, Damian felt much better than the day before, but was extremely hungry and needed a large amount of food again to complete his recovery and sustain his growing and developing body.
However before he left his room to get some food, he had confirmed to himself and was sure that he was onto something, and as soon as he reached that conclusion, he felt a weird sensation within his mind.
He recognised the sensation and knew that it occurred when he had unlocked something within the Golden Flame Inheritance. Damian wanted to jump up in joy and instantly steamed his consciousness into his mindscape where the Golden Flame Inheritance was, leaving his body unconscious on his bed, seemingly asleep.
Seeping his consciousness into the Golden Flame Inheritance he found that he had unlocked another manual that seemed to be some sort of cultivation, but he didn't recognise the cultivation method that had a golden cover, with flames engraved into it.
Before he could check out what the cultivation method was, he suddenly received another manual that seemed to a technique and was shorter than the cultivation level and Damian was overwhelmed with joy.
He knew that he would only unlock things once his body and mind were ready for them, so it must have had something to do with his idea and the realisations that he had during his spar with Milo that helped him open his eyes to wider truths around Internal and External Cultivation.
The Golden Flame Tempering Method
Using the Golden Internal Flames and resources that are dense in fire energy to temper the user's body externally and gives the user immunity to fire and also gives them greater explosive power compared to an ordinary external cultivator.
Matched with the Flame within his dantian that he was still forming and improving until it was completely gold, from the red flame that the Maxwell Family made it to be, it would give him incredible power.
It was an external cultivation method and exactly what he needed since he wanted to get his external cultivation to match his internal cultivation, so that he would be able to break past the Mortal Cultivation Level.
Damian believed that his idea was true wholeheartedly and even if it wasn't, his body would be more stable and powerful if he cultivated both internally and externally, so he wasn't losing anything by doing so.
The effects of the Golden Flame Tempering Method were incredible and he could temper his body using his own flame, other flames and resources that are rich in Fire Energy, such as the beast core of a Fire Beast or a pill that was made with materials that grew in environments filled with Fire Energy.
When it came to resources and beasts, Damian was quite limited as the Gobe Country hadn't opened trade with other countries or explored much of the area around the country, but he was sure he could still find the resources he needed.
[I can ask my mother for a pill that has a lot of Fire Energy and I will repay her for it with the spirit coins that I earn from my missions. But before I begin cultivating the Golden Flame Tempering Method, I need to see what that other manual was] thought Damian to himself.
