Just to show you how ideas are unoriginal, these are all the places that I intentionally copied from. Any others are just pure coincidence.

Chapter 002 – Death

Storage rings are common places in many Xianxia novels, but I got the idea from reading Tales of Demons and Gods and Zui Wu Dao.

Chapter 003 – Awakening

Akiza's pressure points and Dantian are opened by force, done by taking in an outside force, reference to Against the Gods (Chinese Xianxia). Also references baptisms in Hunter X Hunter, where someone uses their Nen/Aura to forcibly open another person's Nen/Aura.

Chapter 005 – Principles

Basic set of beliefs and tenets for a school are common in Wuxia novels. The idea was mostly from Return of the Condor Heroes, where Yang Guo, the main character is an outcast for breaking the norms.

Chapter 006 – Dantian

A big plot point in Condor Trilogy involves the Nine Yin White Bone Claw and and Nine Yang Manual.

Chapter 006 – Dantian

The nine types of energy references many different series. Ki is from Dragon Ball. Aura (Nen) is from Hunter X Hunter. Chakra from Naruto. Mana from Magic the Gathering. Nature is also from Naruto (Sage techniques). Elemental from Fairy Tail (the Dragon Slayers can eat elements to heal).

Chapter 007 – Tears

World Spiritualist Technique is a reference to the Pulse Searching Method in Martial God Asura. Exact same system, but different name.

Chapter 007 – Tears

The fact that you need physical strength to support your abilities comes from Boku No Hero Academia (My Hero Academia in English) where Deku, the main character, breaks himself in the early volumes whenever he uses his power because he cannot properly control it.

Chapter 009 – The Power of Food

The Book of Foodies is similar to the tome acquired from the family techniques by the main character of Zui Wu Dao. Early on he acquires a book that lets him eat food with potent energy that would normally kill him, but the technique allows him to absorb anything he eats.

Chapter 011 – The Power of the Elements

The Water Divination method is taken directly from Hunter X Hunter, though it does not use the leaf.

Chapter 012 – First Breakthrough

Hiding your power level is common for the Z Warriors in Dragon Ball Z.

Chapter 016 – Akira vs Akiza (1)

The constant death and starting over is a reference to All You Need is Kill or Edge of Tomorrow.
