The best way for anyone to learn Pill refinement was to observe someone that was the reason why Zero wanted Lily to be present. The last time Zero talked to Lily about Pill refinement he found out that Lily had problem with flame control and that's why Zero started teaching her about flame control first.
They worked at improving Lily's flame control the whole night and it was only when the sun was rising that her flame control was good enough for her to start refining pill. Again Zero was amazed by her talent to be able to improve her flame control so quickly.
After working on flame control the whole night Zero was ready to start refining pills but this time he was not going to use his Sharingan, one of the reason was that he did want Lily to find out about his biggest secret and Zero did not want to depend too much on the Sharingan for all things and he wanted to use it as a trump card.
Without the help of the Sharingan to Zero was refining pill slower than before put Zero was happy because the quality of the pill that he refined was still as good as when he was refining them using the Sharingan. When Lily gave Zero the herbs that her mother had prepared for him he was shock by the amount of herbs in the space stone that Lily gave to him. The herbs were enough for Zero to refine one thousand cauldrons of Body cleansing pill.
After ten days of tireless work refining pills Zero finally reached his limit and he still did not leave a dent on the herbs in his position now. All Zero managed to do was refine just over 50 cauldrons of pills and he still had a long way to go. Zero skill at refining pills were improving at an amazing speed and now he was starting to feeling confidence that he could refine a level 2 pill. Refining level 2 pills was a very difficult problem was a big challenge for Zero because no one has ever refined a level 2 pill while they were still at Body cleansing stage.
After resting Zero decided that it was time for him to get his revenge against the bronze golem that nearly killed him last time, this time Zero was more than prepared to fight with the golem he put on his Devil king spirit armor and his full body armor that Lily gave to him. The full body armor was a pair of cloths that were made out of beast skill and made it had for swords and other weapons to penetrate through it.
The Devil king armor looked like the armor that solders would wear in the roman mythology movies (Hercules). Begin a Spirit artifact the Devil king armor was made to block more than half of the force that it was hit with.
Zero walked into the training grounds with pride and his head held high knowing that the time for his revenge was soon coming.
When Zero walked into the training ground the golem was already waiting at the other end of the training grounds. "Begin" Zero shout and charge at top speed at the golem holding nothing back his Sharingan activated mid stride, the golem did the same from the other side of the golem. Zero and the golem meet at the middle of the training ground and the golem was not playing and lunched a punch at Zero. After the crashing defeat that Zero suffered in his last fight with the golem this time he was even more careful when facing the golem and wanted to keep his distance from the golem. Seeing the punch coming Zero put all the momentum from running into his legs and leaped and sent both feet at the golem and pushed with all his strength to push at the bronze golem back.
The golem took two step back and that did not even phase the bronze golem it went back to attacking right away put Zero was more than ready for the attack and he managed to change the direction of the attack. The bronze golem kept making one attack after another and was met with the same result time and time again.
With all its attack easily dealt with the bronze golem was starting to make Zero nervous its attacks did not change at all but it was starting to give Zero a different feeling now. The body of the bronze golem was starting to heat up and with attack Zero could feel the change in the temperature of the golem. The bronze golem was not human so its body should not heat up after fighting for a long time and what Zero was most worried about was that he would not be ready for what the bronze golem was trying to do.
While the fight continued Zero noticed that the golem was getting stronger and stronger its momentum in the fight kept increasing and Zero was starting to have trouble keeping up with it. Knowing that this might be his only chance to act before the bronze golem got too strong for him to handle Zero took a chance pushing his body to its limit he exploited the flows in the bronze golems foot work and tripped it and while the golem was falling Zero delivered a punch with all his weight behind it.
The bronze golem was knocked to the ground and a small smile of certification filled Zero face as he saw the bronze lying down but his smile did not last long because when the bronze golem it was as if an animal was let out of it cage. The training ground was quickly filled with a strong oppressive force that made Zero suffocate. Without even needing to be told Zero guessed that this was the Dragon subduing art that was famous in the entire realm.
Seeing the Dragon subduing art Zero confident took a major hit knowing that all this time that he thought that he was keeping up with the bronze golem but it turned out that the bronze golem was not even trying.
