I Can Upgrade Everything

Due to his poor talent, Zhao Yan failed the examination to become an entry-level disciple of the Baiyun Sect... Then, he activated the all things upgrade system. In addition to his own cultivation, he can upgrade anything, which sounds unreliable. So Zhao Yan upgraded his clothes with the attitude of giving it a try. The original ordinary robe was upgraded to a Tai Chi robe, which could rebound or reduce the force of the attack by 50%. This... Try upgrading your shoes. Ordinary shoes are upgraded to wind boots, which increases your movement speed by 100%. Alas, there is an ordinary flower here. After upgrading, it turned into a treasure of heaven and earth. It seems that it can be upgraded again. After upgrading, it transformed into a flower demon... There are also elixirs, spells, and weapons that can all be upgraded. So what if the talent is too poor? I only need to read the spell once and then upgrade it to learn it directly. What should I do if my cultivation level cannot be upgraded? If I directly upgrade the elixir to the highest level, won't it still allow me to break through?
