That night, an old man called and said, Run up the mountain and reach the hut before the sun rises. He said the path is filled with traps; if we don't come before the sun rises, he will not accept us as disciples.
So we ran up to the mountain, and we were hit by many traps due to my brilliant eye sight and 10% brain usage. I dodged most of the traps, but some were so fast that I got hit by them. Tanjiro was hit by a lot of traps and was bleeding, but I didn't help him. I want him to live up to his potential. So he used his nose and started to adapt and continue our journey, and we reached the hut with a lot of bruises and bleeding before the sun rose, and the old man acknowledged us with a nod and told us he would train us tomorrow.
From there, our training arc started. At first, he trained both of us at the same time, but with time, I am adapting very quickly to the training regime, so he asked me, Do you want to complete the training fast? I said no and explained to him that I wanted to enter the selection at the same time as Tanjiro and asked him to increase the training for me. He acknowledged it and started to intensify my training regime. In one year, I completed the training regime and saw weak points in a body and cut them, then started doing stamina building and sword moves and tried to perfect them.
Tanjiro, who completed his first phase and got into second phase training, completed it in half a year and got ready to face the selection.
The day has come for us to depart for the selection. We positioned ourselves, said good-bye to Nezuko, and promised to return victoriously. We bowed to the old man for training us, and Tanjiro mentioned Makomo and Sabito, which caused the old man to get shocked. We depart from the hut, running.
We reached the location after two days of travel. This place is beautiful, but I know this forest is a hunting ground for newbies. I saw characters that are going to be fighting with us in the future and some cannon fodders who are going to die here, so I decided to save them.
Everybody was given different directions to enter the path and survive until the sun rose, which was their condition for passing the exam.
I let Tanjiro fight for himself and kill that big-hand monster. I decided to intervene only when Tanjiro was in a dire situation and started to run and help those who were in dire situations. How did I find them? Simple. I copied Tanjiro's noise talent and trained it very hard, and I can smell and register people's scents. Before we started, I had to register the people's scent. Before we started, I had registered all Cannon Fodder scents and started to follow and help them, give them directions to return, and tell them to cherish their lives. They bowed and started running in the direction I showed them.
After saving all the cannon fodder, I reached where Tanjiro started to fight the big, ugly monster and watched it from afar, not to disturb the battle.When the thing was going to kill Tanjiro, I took the axe and threw it towards the monster with total concentration, breathing. The axe cut the monster's hand clean, and the monster searched for the culprit, but it couldn't find me in that distracted moment. Tanjiro, who woke up and used total concentration to breathe, found the line to the monster's head, jumped on its hand, and ran towards its face with swift motion, used water breathing first form—water surface flash—and cut its head cleanly.
then I came from shadows and started to clap to Tanjiros way of swift execution, and he became embarrassed and thanked me for saving him. I got shocked and asked how he knew; he showed me his nose. "I already cleared some kids who were not fit to be demon slayers and told them to leave. We can stay and spend time until the sun rises." He nodded, and we spent our time talking about experiences. He fell asleep, and I put a blanket on him. I stood up to watch some demons try to reach where we were, but I took swift action and killed them without disturbing Tanjiro.
sun rose, I called Tanjiro to wake up. He was shocked to find he had slept very well in this dangerous forest without thinking, and he realized I had protected him all night. He smiled and said, "Thank you, big brother, for protecting me." I smiled at him and said, "It is a big brother's duty to protect their siblings. There is no need to be emotional. Let's go down the hill."
After reaching the place, only five people were standing: me, Tanjiro, Kanao, Zenistu, and Genya. Then the daughters of Kagaya Ubuyashiki started to talk. Genya, being Genya, started to interrupt demand katana. They explained to him about the selection of ores and provided us with Kasugai Crows. I don't have any crows. I feel depressed, and Genya is trying to put his hand on the children. I appeared on the right side of him like a ghost caught his hand. "How dare you try to hurt children in front of me? You have a death wish, boy."
Genya was shocked and feared because of my action. He fell down on his knees and became pale with fright because of my killing intent. He couldn't breathe. He thought he would die today. He then heard a voice, and everything went normal within a second. The man asked me to look at him, and I slowly raised my head and saw his black eyes, which were like black holes. "Listen, boy, you better act like a proper adult and stop hurting children. If it weren't for my little brother, I would definitely break every bone in your body and take care of the crow properly. If I hear you causing trouble to children and crows, I will find you, and I will break you." He nodded with fright.
Then ore selection proceeded as Cannon Tanjiro used his nose to find the ore. For me, there was no ore, and I felt something was off before I asked them. They let everybody go except me, so I told Tanjiro to go wait for me at the foot of the mountain. He nodded, and I followed them when we reached a tent. The oldest daughter saw me, stopped what she was doing, and asked me, "Sir, why did you save the participants and make them disqualify?" I looked at her and said, "Because they are doomed to die, so I saved them. I have had special eyes from birth. I can see people's destiny with color format, and they are weak."
The oldest daughter nodded and opened a box and showed me an ore, which has sky blue and white lines on it, and said, "It is a rare metal specially left for you by the request of water hashira." The ore is attracting me, and my eyes and nose are saying this is it. I nodded to the lady; she led me out of the tent and whistled, and an eagle came from the sky swiftly and landed on her hand.
A young lady caressed the eagle. "You will aid him in his journey from now on." This eagle nodded, came to me, and landed on my shoulder. "I am Garuda. I will be in your care, Master Rudra." The eagle spoke. Oh man, it's awesome and super cool. It sounds like Almight. "I will be in your care, Garuda." The eagle nodded, and I said my farewells to the daughter and got down the mountain.
At the foot of the mountain, Tanjiro is waiting for me. After seeing me, he waved his hand. When I got near him, seeing an eagle on my shoulder, he got shocked and excited and talked to the eagle, asking all types of questions. The eagle didn't get irritated but slowly answered his question like an adult teaching a child.
After two days, we reach the old man. Seeing us, he got emotional and asked us to celebrate. Behind him, we saw Nezuko wake up. We ran to her and hugged her, and Tanjiro started to cry. I just patted them on the back, trying to let them control their emotions.
