So in the latest chapter we learn that the Spring Autumn Cicada and other high level Gus can only have a single copy of themselves in existence at a time. But that doesn't make sense because the only way for a vital Gu to die is for its owner to die or not feed it. But that doesn't apply to the Spring Autumn Cicada because it gets its food directly from the River of Time and if its owner dies it will just revive along with the owner. So the question is, how could the MC get the knowledge of how to craft the Spring Autumn Cicada? It would only make sense if someone crafted it before and left the recipe and knowledge of it somewhere and that's how the MC found out about it, but if that were the case then the MC wouldn't have been able to craft the Spring Autumn Cicada in the first place because a copy of it would have already existed and its clearly not possible for the original copy to die.

That's not how it works, the owner of the spring Autumn Cicada can decide to make himself explode and use all of his power to go back in time (depending on how much power he used), but he can also easily be killed before he activate it, the Cicada doesn't activate by itself it has to be activated by the user. Moreover the Autumn Cicada only has a 10% chance of success, and this 10% relies COMPLETELY ON LUCK (not on the user), if you activate it and fail you just die completely. Also, the Autumn Cicada has a long cooldown after using it.
The MC got the knowledge of the Cicada from a Ruin where the previous owner and creator of the Cicada (That was a rank 9 gu master). The creator of the Cicada also said clearly that there is no way of making that 10% chance higher. That means that if you are about to die, you can try to use the Cicada, but you will have only a 10% chance of going back in time, and a 90% chance of dying completely. Moreover the Cicada is not omnipotent, it's only a rank 6 gu as of now, and so it can only bring back rank 6 gu master or below, you have to upgrade it to level 7-8-9 otherwise it will only be able to bring back rank 6 gu masters and below, also, even if you upgrade it, the 10% chance doesn't chance and stay the same always.
Moreover, other gu master also have method to neutralized it, when they are fighting there are various moves that blocks the power of time; and that will make it impossible for the owner of the Cicada to use its power to go back in time. (When the owner of the Cicada dies without going back in time, the Cicada dies too)
Also, you can't go back to a time before you were born, since you will have not have a body to connect to because you don't technically exist yet. Also, if you go back to when someone else had the Cicada already, your Cicada (being the one that just came from the future) will die, since only 1 can exist at a time.
