The reason why Wang Yu could kill those soul master beasts was because of Feng Yi energy even only a small piece of it could help Wang Yu fighting those Soul Master Beast. But when Feng Yi saw the Elemental Fox he gave Wang Yu about 30% if Soul Master needed 5% the Elemental Fox needed 30% of Feng Yi energy.

"Kid I will need to rest for an hour i gave you 30% of my energy you must eat the Core of that elemental fox it will help you for sure".

"Okay Master you can rest" Wang Yu Said with a excited expression. He then rushed and searched everywhere the Fox body to find the core. Because Every position of the core depends on the beast type. After finding out that the Core was not anywhere the body he looked through the head. After a second he found it inside the middle of the forehead of the Fox. It was bigger than the Wolf Core he found before, and looked like it have something moving inside of it. It was blue and red flame, He then ate it and sat he is now meditating.

Wang Yu could feel the burning sensation inside his body. It was really hot, But Wang Yu knows that he must succeed taking on this Hotness because if not the effect will not work and it might also damage his Cultivation, That's why taking demon cores can harm your body if you are not sure that you can handle it.

The Hotness became greater and greater, Wang Yu is just using his energy to withstand it. he was already biting his lips on pain he tried not to scream, his lips were bleeding already and blood was flowing down from his mouth already.

Suddenly the hotness was disappearing, Wang Yu felt a slightly relief that he could withstand it. after the Hotness disappeared he continued meditating for 3 hours to retrieve the energy he expended.

After 3 hours he opened his eyes. he looked at his palms and said "I finally reached Rank 29 using that core, Oh what is this!?" then suddenly Feng Yi Said " Its the Red and Blue Flame Symbol, It can boost any flame skill that you use, like its being used by an Elemental Fox." On Wang Yu two hands were a red and blue flame, Red flame on the right hand and blue flame on the left hand but it was not that big. Suddenly a information got into his mind.

It was the way to make the symbol disappear and appear. He tried making it disappear and the flame disappeared, and then he made it appear again and it appeared. He then made it disappear and said " Master maybe you can give me some Fire Skill?" Feng Yi replied with " Haha, Sure thing but you must try your fireball skill first even without the flames and after that try it with flames" Wang Yu Nodded.

He then made a hand sign and right now there was 15 Fireball and he could feel that he can control each and every fireball he created. he then swayed all of it off, Suddenly a Mark appeared on both palm of Wang Yu and he Then Made a hand sign and suddenly 15 Fireball but all of it was 3x Larger than before. Wang Yu Have a Excited and Happy Expression.

"This Flames are really strong!" Wang Yu said. Feng Yi then said "For now try to hide your Flames because it is too strong, They might want to get your hands if they know about it" said while laughing. Wang Yu then said " Yes I know master I will go to the sect for now".

Wang Yu used his Shadow of Wind and goes straight towards the Sect. after 1 hour of travel he could see the Sect Gates already he then took out the badge and then showed it to the guards. For Outer Disciple they could only leave for one month while inner disciple could leave for 5 years and The Core Disciple can do it no matter how many time they want to be out.

Wang Yu then goes straight towards his residence, but he halted when he saw many people going to the Arena. He asked one person and that person said "What you don't even know what going to happen today?, Looks like you have been out, Okay i will tell you, Today is the day you can gain knowledge from sparring the Core disciples!" Wang Yu then said " Thank you for the information"

He then goes toward his residence again, It was very quiet because mostly of the people wanted to gain knowledge from the Core disciples. He then took out one pill of Energy Gathering and sat on his bed he then began meditating. it Took him 2 days and he finally opened his eyes.
