When Mu Jinyu arrived, he listened to an instructor's explanation.
To enter the Tiangan Secret Realm, one not only needs to be of the Human Race, but also requires a special key to enter, which also requires the entrant's blood.
Afterwards, once the secret realm is fully opened, only those who contributed blood can enter, even if later comers are also from the Human Race, they cannot enter.
This is why the entry slots for the Tiangan Secret Realm are tightly held by the Dongyue Mansion and various royal clans.
"Whoosh!"
As the elder of the Yaao Family finished speaking.
Immediately, descendants of the various royal clans and a hundred students from Dongyue Mansion, who were ready to enter the secret realm, squeezed out a drop of blood, splattering towards the assembled ancient jade.
"Psst!"
Almost a thousand droplets of blood poured into the ancient jade, instantly turning the amber-colored jade to a pale red.
"Go!"
