There is a lot to work on he asks for information about rare martial souls and examples of failed or regressed mutations of martial soul incidents. His focus was intentionally on failed half-step mutation of Yu Xiaogang and the martial soul of the poison douluo family.
For the case of Yu Xiaogang, who is also the ancestor of his principal mu en white dragon douluo and his senior beri of his previous life in the DD2 era, his mutation was supposed to be in a stronger direction with the light element attribute.
With regard to the poison douluo family, why are not many strong family members with strong cultivation and powerful poisonous martial soul? As he already knows of his brief history and treatment options are given to them by tang san. He has to cash this knowledge and plan to gain access to yin-yang well.
He first put his theory regarding the reason of poison douluo family low numbers which are confirmed by the pope and her two followers using spirit hall intelligence. Huo yuhao went to poison douluo as hidden envoy from spirit hall along with chrysanthemum douluo. He accurately described the symptoms of martial soul poisoning of the body to poison douluo and his so-called suspicion for poison douluo to possess some miraculous place or treasure which prevented the death of poison douluo before his son. He put a deal from spirit hall, with a seal from bibi dong that "in exchange for that place he has they will treat his son and cure for the future generations of poison douluo's family.
In case if they succeed in findings a cure for his son and his future generation like his granddaughter then not only spirit hall will be given that miraculous place he owns but also to take an oath that if he doesn't join the spirit hall at least he will become a neutral party. At present his supporting for 4th prince for a crown, which he will have to be withdraw. So in the future, if any conflict arises he will not take sides with heaven dou empire or against spirit hall.
Through his discussions, he is also trying to change the aggressive mindset of the pope and her bodyguards that it is not always right to say that "if you are not with ME then you are my ENEMY". We can coerce those who are unwilling to join by a soft approach like what queen juzi of the Sun-Moon Empire did by providing free soul-guided instruments and types of equipment to the civilian population. He admire the approach of juzi as it was history's softest invasion with minimal bloodshed of the civilian population and civilian free spirit masters. He plans to use a little similar approach in the future.
Along with chrysanthemum and poison douluo he goes sunscreen forest. As poison douluo is not very hopeful of his son and family situation, but he has to give a face to the direct letter correspondence from pope bibi dong.
Finally similar yin-yang well scenery comes in front of him. His first plan was:
1. Using purple morning dew for the secondary awakening of his martial soul and opening of the third eye.
2. Using fire apricot and ice grass fruit enhance his physical attribute in advance before accepting silkworm brother and scorpion sister as his martial soul.
Normally he will never use multiple heavenly treasures or suicidal body tempering foolishly but absorbing and releasing the function of his unique golden space in his spiritual space might be more helpful than he thought.
As he possesses his own knowledge of space attributes and memory of his mastery over different attributes in a previous life. the elemental theory knowledge from different personnel and their insights on various attributes like insights light attributes from light dragon douluo, for fire attribute from her class teacher and his senior sister ma xiao along with dark attributes, his fight with evil soul masters and in final tutelage and discussions with silver dragon king gu yuena.
The inheritance of black magician Electrolux along with his unique otherworldly knowledge and power system mostly associated with necromancy, dark and space attributes, with a touch of life, death, and destruction laws due to his exposure with life metal, his discussions with Electrolux, life, and destruction god.
He also gets a few other unnamed insights due to absorption and assimilation of spirit power by his body from the soul master who awakens his spirit, at the time of his martial soul-awakening due to golden space.
He asks permission to use herbs from the yin-yang garden which was readily permitted by a nod from poison douluo. He also asks him to bring his son here as it will be beneficial for his body to endure and recover some poison damage.
After poison douluo goes to bring his son, he also asks chrysanthemum douluo to cultivate and meditate as it is the best spirit mimicry environment he gets in douluo continent especially sitting near the chrysanthemum flower. After that, he immediately uses drops from the fruit of purple morning dew and sits in meditation, same as in his previous life he experiences the secondary spirit awakening and opening of his third eye, and as expected from him this process only uses one-third of the herb efficacy remaining two-third efficacy absorbed and stored in his golden space in the form of purple mist.
This expectant result is a huge benefit to him as it not only wastes any drug or herb efficacy but also prevents any herb compound interactions in the blood which means he can take apricot fruit and ice grass fruit without any negative side effects from any excessive uses of multiple drugs.
He awakens and attends poison douluo and asks to use various common herbs in the garden as his son's diet even including blue silver grass which is healthy food for him due to common grass being tempered by yin-yang well.
After that, he cautiously takes both apricot and yin grass fruit using the jade hand technique and uses it simultaneously and jumps to yin-yang well using Tang san experience he gets with discussion with him in the god realm.
He starts revolving his modified heavenly version of the technique, which is more effective in the assimilation of both drugs as his body starts strengthening and tempered under the effect of dual drugs of opposite nature from inside along with duel tempering from outside by yin-yang well.
As expected absorption function of golden space started, the excessive herb efficacies in the form of red and blue mist were absorbed by golden space and then followed by its gradual periodic release of red and blue mist in small doses in his blood and meridian circulation to be absorbed accordingly. Outside pressure and extreme tempering pressure are also reduced by golden space by absorption of red hot and blue cold qi inside golden space.
There is continuous absorption of blue and red qi in golden space and in the middle of golden space there is the vague shadow of red and blue well start forming along with spreading of vitality spreading in a circle from central well to the periphery. He starts feeling some semiconscious presence start noticing his absorption, it is the semi-evolve consciousness of douluo planet before it was replaced by tang san as he placed his father Tang hao responsible for planetary laws and his mother the blue silver emperor as connecting to the vitality core of douluo plant, after dismantling and destroying this semi-evolve conscious entity (Author's ranting: yeah yeah like douluo planet is your family's house background. father is planetary law, mother connect to douluo vitality core and son tang wulin planned for sea god seat humph. End of author's ranting).
