Chapter 18- Chen Vs Chu Wu
Ji feng Choose a isolated place were no one can get near sea shore and began his cultivation. As expected, It created a horizontal vortex which pulled sea water at an unimaginable speed towards ji feng and got absorbed through ji feng's skin. Human Skins have multilayers. As ji feng born as a human, He still had same method of structure except for the bone covered heart due to his cultivation technique basic nature. As the Sea water gets absorbed, it forms a thin layer inbetween ji feng's outer skin and inner skin. This layer improves its strength as time passed. Ji feng continued this as a regular basis during the day, and went and check up on Chu wu at evening and spend the night with her. Eventhough Chu wu's in meditation state, ji feng still wished to be with her.
After 3 days, Chu wu woken up from her meditation and explained ji feng that she understood the technique and she can perform it with appropriate environment. The next day, They went outside to the sea shore and as usual found an isolated place and started their cultivation. Chu wu's technique allows her to merge her full body with the sand. At the beginning of cultivation, Chu wu suffered heavy pain that she began to shout and she even chose to give up in cultivating, but ji feng persisted for her to cultivate this technique as she considered her future safety and chu wu can't deny ji feng's request and continued her cultivation. Sand body techniques allows the bond between physical elements with the sand. It allows one to think each and every particles of sand as their cells and allows them to control each of their cells and some cells can even protect them on their own depending on the instincts. This technique takes some time to completely master it, as each cells need to be connected with single consciousness and each need to merged with Sand with atmost compatability. Not all the sands can merge with chu wu's cell as the requirement of technique only needs fine sand which have similar shapes that can match Chu wu's physical requirements. Even after merging is done, it can be increased in property by mutation after cumulative increase in merging.
After 2 years of Cultivating peacefully, Ji feng finally completed his Third stage of Demon heart body cultivation technique. Demon heart first stage improved ji feng's blood and bone strength from nomal human being just by cultivating without any requirements, Second stage required lot of blood to increase his blood density to a saturation level upto skin leakage occurs, and the third stage required Salty water Which forms an unpenetrable layer inbetween his skin. He observed his physique for a while and thought that " This Physique is suitable to withstand the mana absorption upto 3%, All i need to do is to find an ancient material with stored mana and to improve my mana quantity".
During this 2 years, Chu wu also cultivated deligently, Sometimes she will collapse by heavy pain suffering and ji feng have always took care of her. After 2 years, Chu wu's full body merged with sand, each and every parts, even blood of chu wu became merged with sand. Chu wu looked like a sand statue after 2 years and only by ji fengs light conversion magic and with certain magic arrays fixed on Chu wu's forehead which can't be seen with normal eyes, her appearance looked normal as before. These magic arrays are stable and it becomes merging with chu wu and will be permanent after few days if not without any heavy damage. Eventhough Chu wu fully merged with sand, She still had a long ways to control sand for her own needs as she still needs to link each sand merged cells into her consciousness. Eventhough she can't fully use her strength, She became immune to any physical attacks as she become like Chen in some aspects. As she even began to compare herself with Chen.
