If he fails, it would naturally be considered a failure.
To be honest, for Jiang Chen, engraving an array on the Thunder Pool isn't very difficult; what is challenging is making this array accomplish his intended goal.
This was Jiang Chen's first time using an array to channel the power of dimensions, and he couldn't guarantee his success.
Therefore, Jiang Chen was gambling in his attempt to craft this treasure, betting on whether he could have an epiphany in the heat of the moment and understand all the necessary elements to do so.
If he could, this would mean the Magic Treasure has been successfully crafted. But if he lost this gamble, his attempt would become nothing more than a joke.
However, at this point, besides trusting his own luck, Jiang Chen had no other choice. Thankfully, he always had good fortune on his side.
Or perhaps it could be said that those who have a wealth of Merit, never disappoint when it comes to luck.
