As Huo Yuhao continued to develop his skills in Ghost and Idol, his proficiency can almost be called perfect mastery. Huo Yuhao knows that he's still inexperienced in anything, so he can never call it perfect mastery.
While he also makes a vow so that he will not follow the evil path of soul master. Huo Yuhao will not be greedy when it comes from any form of desire, he will not show arrogance in life, he will be kind to everyone, he will endure but not forgetting those who spread misery to others, he will not force anyone to do something for his benefits and he must be fair while not taking any side that is harmful to all.
He makes this vow as to restict his action from going stray in his path. There's also a book he made using his spiritual, soul power and the book itself. He found out this book can be considered a soul guide since it used the user own power and increasing the user spiritual power. The book allow the user to make a calm judgement while protecting their mind. He named it the Book of Development.
Over the remaining years before Huo Yuhao is 12 year old he also make a lot of trade using a lot of gold coin he made from his part time work as a butler or maid in the palace, due to his appearance that can almost rival the princess of Star Luo Empire and his kindness he has unofficial title The Saint of Empire. Originally everyone one to call him saintess but due to his gender it became a Saint which make Huo Yuhao finally became happy as all of his work to change his image pay off.
With the gold coin he used it to buy a lot of different plants seeds, stones and even knowledge from the entire of Star Luo Empire. With his new knowledge he designed an all terrain ecosystem within his land, he used the spiritual eyes to find the most suitable point to make a large ray of formation based on his previous dreams and soul guide.
He used everything in his land to create a boundary territory that can allow him sense everything in it. Next he set up the countermeasures in cases someone or something wants to be greedy in his land, all of them will be marked using spiritual power to track their location and action they do. He will strike them with lightning if they do evil action and it will not kill them but is reminder to them.
Then he set up the space array formation to increase the core and inside his territory, there's also a formation that can make anything and anyone to ignore the special zones. He used his spiritual power to guide the elementals energy to specific area until they became the natural flow of nature, it will help him to create a natural habitat for every specific plants he planted in the area.
Once everything was done, he covered his entire territory with spiritual power and asked the plants and beasts if they wanted to move or stay in the area. To which he managed to make a more suitable habitat for them inside another space, he got gratitude from them and detected the power of faith to which he felt familiar. He used most of them to increase the core strength while adding a condition to his entire terrain.
When he returned the next day he used compression of spiritual to make the purest spiritual he had. While he was doing observation of his territory he got and interesting idea which he decided to cover every part of his body with spiritual power. He could feel everything inside his entire body and his martial soul seemed to evolve, his spiritual power was evenly distributed and flowing outside to form a spirit body.
When Huo Yuhao opened his eyes again, he saw his physical body and spiritual body were against each other. He tried to move and began practicing movement using his spiritual body. It felt the same way when using skill Idol, but he felt more natural. He tried to see any changes that he could make with the spiritual body.
After a lot of testing he concluded he can transform any part of his body while also having different effects with the transformation. When he transformed it to became plants, many soul beast plants in the area showed affection towards him. When he became a soul beast the plants stopped talking and their presence was like never existed.
But when he suddenly had the idea to change his gender and sudden shock flowed through his spiritual power, he detected that the Book of Development seemed to have gained a bit of intelligence since his spiritual power became more unstable. He shuddered that he almost became a pervert when thinking about different gender.
Luckily the Book of Development were created and he want to turn into a martial soul while feeling that cretmating an artificial soul is possible in the future.
