I am going to be honest in this review. I enjoyed reading this fanfic, but that does not mean it is good. The MC, who is a demonic sword, does not act demonic in any meaningful way. You could argue that how he acted when he first met Tanjiro was demonic, but realistically any legendary sword would act that way to test its wielder. For the most part, he has been aiding Tanjiro in everything he does, to the point where it feels like Tanjiro is dependent on the sword. Tanjiro becoming dependent on the sword is another issue. Currently, Tanjiro is portrayed as if he cannot think for himself. The MC (the sword) tells Tanjiro what to do, how to do it, and so on. The MC is not really guiding him, but instead giving him direct answers to every problem that comes up. To me, this version of Tanjiro feels like he is nothing without the sword, which leads into the third issue. The MC (the sword) has the capability to permanently boost Tanjiro’s base strength by 30% every time they kill a demon. This has happened roughly 4–5 times from what I have read. However, I do not know if this is multiplicative or additive. Either way, he should be significantly stronger than before at the very least 150% even high if its multiplicative(271%), yet he is still portrayed as weaker than a Lower Moon who was able to pierce his heart almost instantly. Keep in mind, the MC (the sword) also has the ability to boost Tanjiro by filling his body with demonic energy, giving him a 50–100% increase in strength. This would mean he becomes 1.5–2× stronger during those moments, and yet he is still struggling. Even the original Tanjiro was able to face a Lower Moon who was a candidate for Upper Moon and almost defeat him. Yet this version of Tanjiro, who should theoretically be much stronger, is struggling against a Lower Moon who was basically cannon fodder in the original story that was only given screentime just to be killed. And what makes this feels even worst is that right now he is learning total concentrated breathing earlier than his OG counterpart so that another increase to his total strength compared to his OG who did not know TCB and fought a upper moon candidate This does not make sense. But still, I like it. Even though the power scaling and character portrayal feel inconsistent, the idea of an MC as a sword in a fanfic is new and interesting. Hopefully, as more authors try this concept, better versions of it will come out someday.

Didn't we agree that we wouldn't be bad singers?

In his previous life, the singer and songwriter Tao Yao, who ate the northwest wind when she was hungry and drank the toilet water when she was thirsty, had inexplicably transmigrated to a parallel world while she was washing the toilet. However, he found that there was no Jay Chou, Zhou Shen, Deng Ziqi, Faye Wong, and other well-known superstars in the world. There were only a bunch of singers that he had never heard of and their unbearable songs. When Tao Yao, who had countless classic songs from all over the world, met a boss who only wanted to ruin the company as soon as possible, what kind of sparks would there be between a genius and a madman? "What? Didn't you guys say that the lyrics of 'Skateboard Shoes' are at the elementary school level? Why is everyone singing?" " No, didn't we agree that everyone likes a more authentic European and American style? Why is this song,'Young For You', which doesn't even have a standard pronunciation, so popular?" "Hey, hey, that's too foul. How can a random song from the northeast that sings Two-people Rotation on the street become popular? What the hell is this 'Xianer'?"

I'm really a spirit contract master

The many races on Planet Kaga were in constant conflict, and evil gazes were watching the entire planet through the spirit world. Any intelligent creature had the hope of awakening their psionic powers through the omnipresent spirit world and becoming a powerful psionic. There were Psionics who grasped elemental powers, Psionics who tempered their bodies, and Psionics who sublimated their souls. Among them, there were even a few psionics who had the hope of obtaining special knowledge from the spirit world and transforming it into their own talents. He had transmigrated to this world through land and air. Due to the transmigration, his soul was different from the rest. At the age of fifteen, he had awakened his psionic powers and became a spirit contract master who used the power of the soul to contract spiritual beasts and other living beings. He could even see the various knowledge contained in the spirit world when he awakened and broke through, and choose the talent he needed! [Perfect Body (Immortal): There is no limit to the strength of the body. As long as you train, you can continuously increase the strength of the body.] [God of War's Heart (Main God): Born for battle. The more you fight, the stronger you become. What can't defeat you will only make you stronger.] [Lord of Storm (Main God): You are the Lord of the Sky, the Air, and the Storm.] [Psionic Affinity (Legendary): Innate affinity with psionic energy, absorbing psionic energy at a speed far exceeding that of ordinary people.] ………… Looking at each and every one of their incomparably powerful talents, Lu Kong felt that something was amiss. Speaking of which, I'm a spirit contract master, why don't I have the talent of a spirit contract master? Several years later, Lu Kong punched an evil god that had descended. He said indignantly,"I told you I'm a Spirit Contract Master. Why didn't you believe me?"
