I Have A Bunch Of Saint Apprentices

*As the a transmigrator who had the system in this cultivation world his system was strange. 
Even though he realized that he was not only a cripple without any cultivation talent.
And the system he brought along was a super teacher system. 
He could only be a teacher, not strengthen himself. He still step on the path that could allow him to become an immortal. 
That was to take in the disciples! 
But still he wasn't able to complete his goal before the lifespan was exhausted. 
Until eight hundred years later, When this cultivation world had became modern He had finally came back to life! 
"Ding Dong, the last disciple of the host has successfully attained sainthood. The Super Mentor System has been activated once again."  
"Congratulations to all of your disciples for achieving the Great Dao and breaking through to the Great Sage Stage. You have completed the Great Dao Oath and the heaven defying Life Changing Program is about to begin." 
Now in this modern cultivation world where all his disciples had become top-notch big shots, What is he going to do？ 
Could his disciples still listen to him? 
What kind of intrigues will he be involved in？ 
Disciples, quickly come and feel the care and concern of your master for being eight hundred years late!
