For those that are confuse why Wang Li decided to be adopted by Grandpa Jack at first was because Grandpa Jack was the village elder. Village elder won't be poor as he is the leader of the village. With it Wang Li can live without worrying for food nor place to sleep till age 6.
That does not mean he is a calculative and ungrateful person. He needs to grow from age 1 till age 6 so he need someone to take care of him and he also plan to repay Grandpa Jack. However, as they say 'Things don't always go as planned'. He got a Heavenly Physique and he was born directly at age 2 so it safe him from the trouble of being a baby. As for why he decided to be born at Holy Soul Village was because the Soul Land MC was living at the village. There is no better way to become friend with Tang San as he won't get too suspicious of Wang Li as he is a child. He will also need Tang San help for fighting technique. If he have heaven defying cultivation manual, then Tang San has the technique to leapfrog opponent.
Wang Li as a person from 21 century, he naturally posses trait from 21 century and that is laziness. In the first place, he decided to help Tang San was because he want Tang San to do all the fighting if possible. He just want to become strong to experience the feeling of becoming strong and also the feeling of cultivating. That does not mean he like to fight and all kind of stuff. He is just an ordinary person from 21 century, so he will have trait as someone from 21 century.
He will mature though. As he lived in Douluo Continent where the strong prey on the weak. He will mature and his resolve will naturally become stronger.
I will made the appropriate plot for Wang Li to mature. Don't worry.
Anyway, back to the story. ENJOY
=====================================
As Wang Li arrive at Grandpa Jack house. He knock twice on the door and called out.
Wang Li:Grandpa Jack, I have brought you some vegetables. Please open the door.
Grandpa Jack:Alright, I am coming.
The door open and a elderly man walk out using a cane to support his walking.
Wang Li: Good afternoon Grandpa Jack.
Wang Li greet with a slight smile.
Grandpa Jack:Good afternoon Xiao Wang. You have bought vegetables again. Thank you as always.
(Xiao Wang=Nickname just like Tang San)
Grandpa Jack reply back with a greet and amiable smile.
After greeting, Wang Li walk inside the house and says.
Wang Li:Your welcome Grandpa Jack. Should I put these vegetable at the table?
Grandpa Jack:Yes, just put it at the table. I will use it to cook later.
Wang Li:Alright Grandpa Jack, I have brought you the vegetable. I have things to do so I need to go first.
Grandpa Jack:Won't you stay to have some lunch with me?
Wang Li:Thank you for the offer but I have already cook lunch at home. Bye bye Grandpa Jack.
Grandpa Jack:Alright, see you tomorrow.
Wang Li walk out of the house and went to the forest. He start to run to arrive at the highest point in the forest. He need to absorb sunlight to advance his Yin Yang Physique so the closer he is towards the sun, the better the effect of the sunlight as it contain more Yang energy.
He usually cultivate Yin Yang Manual at 12 pm and 12 am. That is the time where the Yin Yang energy from the sun and moon reach it's peak. It usually only last for 1 hour. Cultivating at that period of time will provide 3 times the result compare to other time he cultivate. With it, Wang Li only need to cultivate his body for 1 hour while getting the result of 3 hour.
Wang Li does not like to waste time as his schedule was constantly filled with things to do. So he will safe as many time as possible. Even the time of him sleeping was less compare to other kid. He only sleep for 5 hour a day which is barely enough for him to not interrupt his body growing. He only sleep for 4 hour at night and 1 hour at evening. His body can't handle constant training without rest. He still haven't reach the stages where he does not need to sleep nor rest. Sleep is for mental recovery while rest is for physical. Luckily he have cultivated the technique the God granted him. If not, he will surely collapse with his filled schedule and the amount of time he use to sleep.
Arriving at the summit inside the forest, he sat at the floor cross legged and he closed his eyes. He start to meditate to absorb the energy from the sunlight.
After 1 hour, he open his eyes and breath out some black mist from his mouth. This is the impurity inside his body. This technique will push his body impurity out each time he finish a session of body cultivation. Even though the amount of impurity forced out from his body was less, however quantitative accumulation will lead to qualitative changes. After training this technique for years, his body will be cleanse from impurities.
Wang Li:Hahhhh, it really take quite a bit of time to reach the third stage of Yin Yang Manual. I have already accumulare more than 1 month of energy from sun and moon and it's still not enough to break through the second stage. With my progress, I probably need to accumulate Yin Yang energy for 1 more week before I can enter the third stage of Yin Yang Manual.
Yin Yang Manual was different compare to Infinity Manual as it have stages and each stages require more and more energy to break through. While Infinity Manual does not have stages and can be constantly train without meeting any bottleneck.
Yin Yang Manual is a bit similar with Heavenly Attribute Manual as both manual have it's own stages. However, Yin Yang Manual does not need Spirit Ring to advance each stage. Unlike the Heavenly Attribute Manual that require Spirit Ring for each stage bottleneck, Yin Yang Manual only require Yin Yang energy to accumulate and it will break through without problem.
However, the Yin Yang Manual for third stage and seventh stage was different compare to other stages. The third stage require the user to accumulate huge amount of Yin Yang energy and form a mini sun and mini moon inside his body. This stage can be regarded as the turning point of Yin Yang Manual as creating a mini sun and moon inside human body needs lot of Yin Yang energy while having a high requirement for the physical body. This won't be a problem for Wang Li as he has the Heavenly Physique coupled with his Yin Yang Physique that he cultivated.
Upon succeed in creating a mini sun and moon inside the physique, it will allow the user to cultivate his physique even in places that have none Yin Yang energy. This is because the user can use the mini sun and moon as a medium for his physique and Spirit Power. The user can inject the mini sun and moon with Spirit Power. This will allow the Spirit Power to change to energy belongs to Yin Yang and it will be directly used to cultivate the body.
If the user cultivate in Yin Yang places, the result of cultivating will double if the user have created a mini sun and moon. This is because the speed of transforming Yin Yang energy from the surrounding to pure Yin Yang physical energy are faster compare to the first and second stage of Yin Yang Manual. The mini sun and moon act as a medium to transform the energy from surrounding to pure Yin Yang energy. This will greatly increase his speed when he refine and purify the Yin Yang energy from the surrounding.
The mini sun and moon will also act as absorber of energy from the damage he received. The energy that can be absorb from his opponent are only Yin Yang attribute and poison. The Yin Yang attribute attack will be refined by mini sun and moon to transform to pure Yin Yang physical energy while the poison will be absorb by user physique to allow the user to have higher resistance and immunity towards poison. The poison can't be refine by mini sun and moon as the poison will directly burn to ash or freeze to the point of turning into cold breeze. So it can only be use to raise the immune system towards poison.
While the seventh stage was another turning point as it require a lot of Yin Yang energy to break through from the sixth stage to seventh stage. If Wang Li continued his body cultivation without having any heaven and earth treasure or heavenly land for cultivation, he will need at least 10 year to break through the sixth stage. The accumulation of Yin Yang energy was more than 100 times the energy he require to break through the fifth stage to sixth stage. That is because the seventh stage involve the evolution of mini sun and moon.
The seventh stage will not only bring him qualitative changes in his physique, it will also increase the benefit of mini sun and moon. The mini sun and moon will evolve and bring it's benefit up a notch higher and directly allow the user to be the controller of Yin Yang energy. This will allow the user to understand the Law of Yin Yang.
Most people knew that Time and Space ranked second in Law while Law of Nothingness ranked first. However, in actual the Yin Law and Yang Law also ranked second just like Time Law and Space Law.
The Yin Law have control over ice, water and many more as long as they have characteristic belong to cold. The Yang Law on the other hand control all fire, essense fire and many more as long as they have characteristic of heat.
That is why, Wang Li cultivation manual was heaven defying. By cultivating the manual to the peak, he can have full control over Yin Yang Law which is consider absurb in Soul Land Universe. Most God in Douluo Divine Realm only chose 1 Law to cultivate as even 1 Law need to cultivate for a long time. Most God can't reach the peak of Law as it was too deep to be fully understood. Only those low ranked Law can be fully understand by the 1st Class God or God King.
However, Wang Li can completely understand the Yin Yang Law by just cultivating the manual. With it, his understanding of Yin Yang Law will be as deep as those God King.
