The letter handed over by Elder Qingyang was protected by layers of exquisite, green lotus-shaped prohibitions. While not overly powerful, they were intricate enough to deter anyone from trying to open the letter.
Looking at it, one could see what appeared to be a giant green lotus made up of thousands of petals, which induced a dizzying sensation.
Any attempt to open the letter would trigger the green lotus prohibition's backlash, preventing it from being easily opened by just anyone.
On his way, Ye Rong couldn't help but feel curious, but after a brief attempt to open the letter, he gave up. The backlash of the green lotus prohibition could potentially end up destroying the entire letter when trying to open it.
If the time limit was exceeded and the task failed, there would be no reward. However if the letter was destroyed, there would certainly be additional punishments.
