"That is because when the eight countries signed the competition agreement, the age of the participants is not clearly stated in the agreement.
"The agreement only clearly stated that all contestants have to pass the branding substance reaction test.
"In the eyes of the various countries, the reaction of the branding substance meant that this person had taken the awakening potion to awaken.
"The awakening potion had only been around for half a year, and those who took the potion to awaken would generally not cultivate for more than half a year. The branding substance reaction test is enough to ensure that the participants' cultivation time was fair.
"Therefore, the countries did not agree on the age of the participants in writing.
"The reason why the world competition is held as a youth competition is that the awakening potion is used on youths above the age of 14 and below the age of 18. The probability of awakening is the highest.
