Once Naina taught Zuko the method of cultivating these arts, Zuko gave in all that he had and cultivated these arts all day and night. The arts that Naina passed on to him were of fire that NWO practiced and the other art was of disguising oneself and it was also a trademark art of the Knights of justice. Although Zuko had no prior knowledge of martial arts but once when Naina provided him the preachments, Zuko showed his talent for martial cultivation. In just two weeks, Zuko had passed the beginner's level for both arts. He had a higher talent for disguising art than the art of fire which was more based on explosive strength than one's control over oneself.
Both Zuko and Naina had been in that place for more than two months, practicing all day and night. Naina was busy with her cultivation and in free time she would study the torn map of the Hanging garden, whereas Zuko was all the time studying his arts. With his talent, Zuko now was at the intermediate level and was progressing in a beastly manner.
During this period, neither Naina nor Zuko stepped outside the hanging garden. With Nania's strength and abilities, they had no reason to go out to fetch things as Naina had everything at hand.
"What is that piece of paper that you study all the time." appeared Zuko from the corner of the cave and had a smile that showed his blissfulness. At this moment Zuko gave off a different sort of aura not like the one that he had two months before.
"It seems you have achieved a breakthrough once more." Naina when say Zuko appearing from the cave, she nodded appreciatively. "With your beastly talent, I am afraid you will soon dominate all the powers at that time do take care of me, don't abandon me, my lord." Naina then joked with Zuko and when he arrived by her side, she showed him the torn out part of the map. "This is the map of the Hanging garden but the other part of the map is with Skulls And Bones. With only this torn out piece, it is not possible to decipher the mysteries of this place."
"Can I have a look for a moment." Then Zuko took a look at the map. " Yeah, this map is indeed quite complicated." Said Zuko when he passed back the map.
Their training continued like this when one day Naina told Zuko that she had some work to do and left the Hanging garden. while she was gone, Zuko was still submerged in his cultivation only when he broke through once again did he stop for some rest. Although Zuko was resting, he still was thinking about the arts and their cultivation methods and the different affairs that Naina informed him of. While he was considering all these matters, he suddenly thought of the map that Naina showed him. When he pondered over the map for some time he comprehended the map. It turned out that the map was always complete it just so happened that, the map was drawn in a bit mystifying way, the person had to solve a puzzle inscribed on the map and how did Zuko do that, it was just a coincidence. The cave that Zuko trained in different murals drawn all over it so when Zuko was training there he would also study them to relax his mind but to his fortune, Zuko coincidently completed the map. Zuko was quite happy that he completed the map and waited for Naina to surprise her. During this period while he was waiting for Naina, a thought clicked his mind. It was this thought that made him realize many loopholes during his interaction with Naina.
Darkness and silence lingered in the Hanging garden, a boy of eighteen years was sitting cross legs and a fire was lit in the space above him. This boy was non-other than Zuko, who was at this moment covered all over in sweat, small beads of sweat were apparent on his face and many on them fallen to the ground. There was even a sweaty stench in the surrounding air. With a woosh, the lit fire extinguished and Zuko gasped heavily.
"That is indeed impressive, I never thought that your talent is so high for fire art." Complimented Naina joyously.
"It is all thanks to you." smiled Zuko sweetly. "Guess what, I have a surprise for you when you were gone, I pondered over the map that you showed me and you see I comprehended the map completely and the new map looks like this." Zuko took out another piece of paper and handed over to Naina.
Naina when studied the map, was surprised that it indeed was the map of the entire garden and most importantly the map was complete. She looked at Zuko with amazement, "How did you do it." Naina was all smiles.
"I was just a bit lucky that's all." Both were smiling like fools.
In the depths of the Hanging garden, two figures were moving side by side in a very careful manner as they had already come by many traps but with Naina's strength, both Zuko and she were able to overcome all the difficulties. They were right now before a grand gate which was made of pure gold. when Naina pushed it open, a very terrifying aura assaulted them, bringing fear and terror."Do not fear, it is just the aura it will not hurt you just stay by my side and you will be safe." Comforted Naina.
Inside the gate, there was a temple in the center of which was an object the size of a baby's fist. It exuded that strong aura that the entire place gave off. Both Naina and Zuko approached the object with great caution, Naina signaled Zuko to take the object from that certain field. Zuko did as he asked to do but to Naina's surprise, that act did not trigger any defensive mechanism.
"Okey, pass it ove... are you ok, are you hurt somewhere?" Naina spoke concerned.
"You are not Naina, why did you bring me here?" Zuko stepped back from Naina, he turned around and dashed towards the gate.
"You think you can escape me." Naina too ran after Zuko. Within no time, before Zuko could reach the gate, Naina caught up to him and then kicked Zuko in the abdomen. With the force that Naina had, Zuko flew in the air and then crashed on one of the pillars of the temple, blood spurted from his mouth and nose and Zuko lied still on the ground, unable to move even a single muscle. "What do you want from me. What have I done to you." Zuko showed great pain on his face as he really felt being wronged.
"Oh, you have done me nothing wrong but what if you had joined our foes then, then you would become a great headache for us. But now, it does not matter because we have trapped that bastard and we do not need your help." With that, Naina kicked Zuko once more then she snatched the crystalline object from Zuko and started inspecting it. "This... this is just a normal crystal." Naina hurled the crystal breaking it into pieces, "You were here before, and you already have the treasure right. Where is it?" She kicked Zuko once more and with greater force than before but to her surprise, her kick passed through Zuko's body.
"You realized it too late." With a slash, Zuko cut off one of her arms and then pierced the sward in her chest, "I came to know that something was amiss when you said that the map was incomplete whereas it was complete, and your disguise art that brought even more discomfort. I suspected you not to be Naina the moment we met. You actually disguised yourself as a wrong girl and you must be thinking that why then I accompanied you. Well, that was because I could not resist you and agreed to everything. Now that I am, you should start speaking or die." with another slash, Zuko cut off the other arm as well.
"Even if I say everything you will not let me go, even if you do so they will not leave me. Go ahead and kill me."
With one more slash, Zuko then beheaded Naina, "As you wish. I can not forget that you just tried to kill me."
It turned out that when Zuko completed the map, he went inside the Gate that both Naina and he entered earlier, inside the same temple, he found an art book-THE ILLUSION. With the help of a special environment and the art that he learned all that time, Zuko then laid a deadly trap. Although Zuko was not that efficient in illusory art, the temple provided a lot of help that Zuko used in his best interest.
when Zuko killed Naina, he did not leave just like that, he stole all her belongings that included her jewelry. After that, he set off from that place. Zuko was still in the dark as Naina did not tell him anything and now, he is in a land that he had no idea of.
when Zuko exited the Hanging garden, he found himself in a very deserted place, there was simply no one around. It was like an ancient civilization abandoned long ago. The abandoned empire extended hundreds of miles in all four directions, it was day time and the daylight was of great help to Zuko. Since Zuko was at the most elevated part of the capital, in his mind Zuko sketched a map to exit.
