After getting the rewards from the simulation then used his sword training experience and battle experience and cultivation experience
then does not use level 79 soul power to his body but to his martial soul because after communicating with his martial soul it can independently cultivate
Because of 10thlevel innate soul power,the martial spirit mirrorbeast soul age is 10*1000=10000,so the soul age of mirrorbeast is 10000 and then using simulation soul power mirrorbeast can also cultivate that is in this first simulation get 79th soul power of body so if it is transferred to mirrorbeast then it's soul age is (79*1000=79000)+10000=89000,so Itsuke tranfer his obtained simulation soul power to his martial soul so that it can get stronger and quality of martial soul will also be improved.
After his simulation he also practiced with the simulation experience and also cultivation also going smoothly. After some hours of training he stop his training and get rested.
After resting he get up in the morning as control the small world energy to shift to his resting and training space so that he cultivate more hours with out getting tired and quality of his soul power also improved.
It's his second day in the small world and does not simulate but convert the simulation chance to points so he can buy some thing for his use in the system store.
After that he cultivate some times and rests and simulation experience is large so that he has to digest his simulation experience slowly so day by day he cultivates and rest and some times he does not stimulate then he convert the simulation chance to points and cultivate swords.
