Maybe it's a time - based element. Naruto could use this new element to manipulate time in a limited way. For example, he could slow down time for his opponents during a fight, giving him an edge. This would add a whole new dimension to his combat abilities.
Element New had many stores in Beijing, including Sanlitun, Zhongliang·Xiangyun Town North District, Kerry Center, etc. These stores provided the services of western restaurants. The decoration style was consistent, and the storefront was spacious and bright. Among them, Sanlitun Store and Qiaofu Fangcao Store had better product stability and service level, so I recommend eating at these two stores. These two stores were located in the mall, surrounded by cinemas, branded stores, etc., and parking was more convenient. It should be noted that Element New Restaurant only serves brunch on weekends. There are more people on weekends, so it is recommended to book in advance. As for the operation of other stores, it was still uncertain. Customers could consult specific stores or contact the head office for more information.
Beijing New Element Restaurant was a Western fast-food restaurant located on the first floor of Yidi Port Commercial Center, No. 18 Jiuxianqiao Road, Chaoyang District, Beijing. It was a brand under New Food Tide Catering Management (Beijing) Co., Ltd., belonging to an American chain restaurant group. New Element Restaurant's business hours were 11:00-22:00 from Monday to Friday, 10:00-22:00 on Saturday and Sunday, and 10:00-16:00 on weekends. It was suitable for couples to date, family gatherings, friends to eat together, rest and eat casually. The restaurant had several branches in Beijing, including Yidigang, Sanlitun, Blue Harbor, Shunyi Xiangyun Town, Qiaofu Fangcaodi, Kerry Center, Fenghuang Hui, Wanliu Huilian, and Chaoyang Joy City. However, according to the latest news, New Element Restaurant announced that it was going through bankruptcy and would close all its stores.
Perhaps it's through a special encounter. He could meet an ancient being or a powerful sage who reveals the existence of this new element to him. The being might see Naruto's potential and decide to guide him in unlocking this new power. This would also introduce new characters and lore to the fanfic.
The 'revelations' can add a lot of drama. For example, a revelation about Tony's past mistakes might make Peter see him in a new light. It could also be a revelation about Peter's hidden powers that changes how Tony approaches training him.
One possibility could be a 'Lightning - Fire' hybrid element. Naruto might discover it during an intense battle where he tries to combine his Rasengan (which has a spinning, chakra - based nature) with both his Lightning Style and Fire Style techniques. He realizes that by carefully mixing the raw power of Lightning and the intense heat of Fire, he can create a new element that has the ability to cut through almost anything like Lightning, but also has the burning power of Fire.
When a girl discovers a new beach, it can be exciting. The new beach might have unique shells that she has never seen before. The sand could be a different color or texture. She could also discover new sea creatures in the tide pools, and the sunsets there might be more beautiful than any she has witnessed before.
The 'Hydra' element makes the relationship between Steve and Tony much more complex. Normally, Steve is seen as a paragon of virtue, but with the Hydra influence, Tony becomes very distrustful. It's like a complete shift in their usual dynamic. Steve may act in ways that are contrary to his true self, which confounds Tony and makes him both angry and sad.
