In my opinion, they're both great in their own ways. The story of Xenoblade Chronicles 1 was classic and engaging, while Xenoblade Chronicles 2 has its own unique charm and depth.
Alveoli irrigation might have some effect on the lungs. Lung washing could easily cause lung function disorder, lung failure, partial loss of lungs, lung edema, and other conditions. Lung-washing required an anesthetic injection, which had adverse effects on the human body. In addition, lung washing could lead to complications such as lung infection, spontaneous pneumothorax, and asthma. If the operation was not standardized, it might also cause hemorrhage of the trachea, edema of the throat, etc. However, the specific effects and side effects may vary depending on the individual. If there is no obvious chest tightness and short of breath, it is not recommended to perform lung cleansing. Generally speaking, lung washing was an invasive operation with certain risks and side effects.
In a 'naruto x pneuma fanfic', perhaps Pneuma has some knowledge that Naruto needs to save Konoha from a new and mysterious threat. Naruto, being the curious and brave ninja he is, travels to Pneuma's world to learn from her. Along the way, they develop a friendship and Naruto brings some of his ninja skills to Pneuma's world, while also learning new abilities from Pneuma.
One main theme could be the connection between breath and life. Since pneuma is related to breath, it emphasizes the importance of this life - giving function.
The term 'pneuma' has been used in various religious and philosophical traditions to denote a life - giving force. In the context of the 'pneuma breath of life story', it could be a narrative that delves into the origin of life from a spiritual perspective. For example, it might tell of how a divine entity bestowed pneuma, this breath of life, upon the first beings. This could be compared to the creation stories in different religions where God breathes life into man. It might also explore how this concept of pneuma affects our understanding of life, death, and the afterlife, as well as our relationship with the divine or the cosmos.
Maybe an evil sorcerer from a third, unknown dimension who sees the potential in both Naruto's chakra and Pneuma's power. He plans to steal their powers to become invincible. He starts by creating unrest in both their worlds, pitting their friends and allies against them. Naruto and Pneuma must figure out his true identity and stop him before he succeeds in his devious plan.
One common theme is friendship. Just like in the game, fanfics often explore the deep bonds between the characters. For example, the relationship between Rex and his Blades is further developed in many fanfics.
