Gu Xijiu had been with him for quite some time. Hence, she knew that no one should disturb him whenever there was a purple glow surrounding his body. Besides that, he needed at least another six hours, and no one should move him or even touch him during his training.
She informed Long Siye about it, and she considered him as a nice person as he immediately called two of his disciples who already possessed a spiritual power of level seven to be Di Fuyi's guardians. Both of them would guard the door so that no one could disturb Di Fuyi.
Gu Xijiu could finally depart peacefully knowing that two guardians were protecting Di Fuyi.
Long Siye was right. If someone attacked the person inside the room, Gu Xijiu would have no chance of fighting with them if even Long Siye's disciples could not deal with them.
